1. Technical field
[0001] The present invention relates to a backpack, in particular to a backpack for biking.
2. Description of the prior art
[0002] In recent years, backpacks for sports applications have become more and more popular.
Backpacks are useful for many different sports, in particular for outdoor activities
such as hiking and biking. In order to comfortably carry the backpack on a wearer's
back, it is known to provide cushioning shoulder straps, e.g. straps comprising a
cushioning material which extend over the shoulders of the wearer of the backpack.
[0003] For example,
US 2011/0290843 A1 discloses a backpack having a convex back panel, wherein the convex back panel of
the backpack may curve outward from the center of a wearer's back to minimize contact
between the backpack and the wearer's back. The backpack may have a pair of shoulder
straps operably connected to the convex back panel to secure the backpack to the back
of the wearer.
[0004] Furthermore,
US 6,164,509 A discloses an ergonomic bookpack with a series of top straps, side straps, bottom
straps and optional support members serving to move the bookpack center of gravity
higher in the bookpack and closer to the wearer's body, significantly redistributing
the load of books borne by the wearer's shoulders along a longer portion of the body
and the back.
[0006] However, the backpacks known in the art do not allow an optimal and secure adjustment
of their position on the wearer's back. An optimal and secure adjustment, however,
is highly important for performance oriented applications such as downhill biking,
where the backpack is subject to significant forces caused by gravity and sudden impacts.
[0007] Therefore, the underlying problem of the present invention is to further optimize
backpacks and to at least partly overcome the above outline difficulties in a secure
positioning of the backpack on the wearer's back.
3. Summary of the invention
[0008] The above-mentioned problem is at least partly solved by a backpack according to
the independent claims. Advantageous embodiments are contained in the dependent claims.
It has to be noted that any backpack according to claim 1 and its dependent claims
may in addition also comprise features of the backpacks according to independent claim
8 and its dependent claims.
[0009] A first aspect of the present invention relates to a backpack comprising a main body,
at least one cushioning shoulder strap and at least two stability straps individually
connecting a distal part of the at least one cushioning shoulder strap to the main
body. In the context of the present invention, the at least one cushioning shoulder
strap has a proximal part closer to the main body and a distal part more away from
the main body. Therefore, the proximal part of the cushioning shoulder strap may also
be referred to as an upper part of the cushioning shoulder strap that is adjacent
to the wearer's shoulder and the distal part may be referred to as a lower part of
the cushioning shoulder strap.
[0010] Any undesired change of the position of the backpack during sports applications such
as downhill biking will impair the performance of the wearer. The inventors have realized
that the provision of two stability straps for a cushioning shoulder strap is sufficient
to firmly and comfortably maintain the backpack in its proper position on the wearer's
back. Therefore, an unintended movement of such a backpack on the wearer's back, for
example towards the wearer's head, can be reliably avoided.
[0011] The at least two stability straps may be connected to the main body at a first and
a second stability anchorage, wherein the first stability anchorage may be arranged
closer to a proximal part of the cushioning shoulder strap than the second stability
anchorage.
[0012] For example, when the backpack is used on a wearer's back, the first stability anchorage
may be arranged closer to the shoulder of the wearer than the second stability anchorage.
Such an arrangement of the stability anchorages of the stability straps can further
optimize the secure positioning of the backpack.
[0013] In some embodiments, when the backpack is used on a wearer's back, the first stability
anchorage may be arranged in a thorax area of the wearer. Moreover, the second stability
anchorage may be arranged in a waist area of the wearer. Thus, the first stability
anchorage may be located at a middle part of the backpack and the second stability
anchorage may be located at a lower part of the backpack. These embodiments further
help to avoid undesired movements of the backpack along the wearer's back as the distance
between the stability strap at the thorax area of a wearer and the wearer's armpit
is much smaller than for the straps of conventional backpacks. Therefore, even in
sports applications like downhill biking with high external forces, the described
backpack can essentially remain at an adjusted position on the wearer's back.
[0014] In some embodiments, the distance between the first stability anchorage and the second
stability anchorage may be smaller than the distance between the first stability anchorage
and a proximal part of the at least one cushioning shoulder strap. For example, when
the backpack is used on a wearer's back, the distance between the first stability
anchorage and the second stability anchorage may be smaller than the distance between
the first stability anchorage and an upper end of the main body which is adjacent
to the wearer's shoulder. The inventors have noted that such a geometry further improves
the secure adjustment of the desired position of the backpack.
[0015] In some embodiments, the at least two stability straps may be provided as a single
strap extending from the main body to the distal part of the at least one cushioning
shoulder strap and back to the main body. By providing the two stability straps as
a single strap, a simple and cost-efficient construction can be provided. In addition,
it allows to easily adjust the stability straps, for example to simultaneously tighten
the two stability straps simply by shortening the overall single strap.
[0016] Another aspect of the present invention relates to a backpack comprising a main body,
at least one cushioning shoulder strap and at least two coupling straps individually
connecting a proximal part of the at least one cushioning shoulder strap to the main
body. The at least two coupling straps are adapted to adjust the position of the proximal
part of the at least one cushioning shoulder strap. Moreover, the at least two coupling
straps may be adapted to adjust the position of the proximal part of the at least
one cushioning shoulder strap in a lateral direction which is orthogonal to the longitudinal
extension of the at least one cushioning shoulder strap.
[0017] Whereas in the prior art mentioned above the cushioning shoulder strap is attached
to the main body without the possibility for any adjustment, the embodiments of the
invention provide a fundamentally new approach for adjusting the position of the backpack
on a wearer's back and improving the wearer's comfort: Having two coupling straps
allows to adjust the position of the proximal part of the cushioning shoulder strap
not only so as to obtain a tighter fit but also in other directions, for example in
a lateral direction, to adapt to different shoulder widths.
[0018] In some embodiments, the at least two coupling straps may be connected to the main
body at a first and a second coupling anchorage. Preferably, at least one of the first
and second coupling anchorages is arranged on an inner surface of the main body.
[0019] In some embodiments, the at least two coupling straps may be provided as a single
strap extending from the main body to the proximal part of the at least one cushioning
shoulder strap and back to the main body. Similar to the stability straps, such a
construction reduces manufacturing costs and allows for an easier tightening.
[0020] In some embodiments, the backpack may comprise a first and a second pair of coupling
straps, wherein the first pair is connected to a proximal part of a first cushioning
shoulder strap and to the main body and the second pair is connected to a proximal
part of a second cushioning shoulder strap and to the main body. Moreover, a coupling
strap of the first pair may be connected to a coupling strap of the second pair. Similarly,
such an arrangement facilitates the manufacture and the adjustment of the fit, as
only a reduced number of couplings straps must be adjusted.
[0021] Moreover, the connection of the first pair and the second pair of coupling straps
may be arranged on an inner surface of the main body. Such arrangement can avoid an
unintentional disconnection of the secured connection between the first and second
pairs of coupling straps during sports applications such as downhill biking or backcountry
snowboarding, where a wearer of the backpack may be in dangerous situation as they
may have a touch with trees and bushes.
[0022] In some embodiments, the main body may comprise a back panel. Such a back panel may
provide support for the main body of the backpack and may minimize the contact between
the backpack and the wearer's back. As a result, a durable and breathable backpack
may be provided for sports applications.
[0023] In some embodiments, at least one of the lengths of the at least two stability straps
may be adjustable. Moreover, at least one of the lengths of the at least two coupling
straps may be adjustable. Such embodiments provide a higher degree for varied adjustments
of the backpack's position on the wearer's back so that the optimized wearer's comfort
can be achieved.
[0024] In some embodiments, the backpack may have two cushioning shoulder straps and at
least one supporting strap connecting the two cushioning shoulder straps. The supporting
strap cooperates with the stability straps and/or the coupling straps to maintain
the two cushioning shoulder straps at a comfortable and secured position on a wearer's
back.

of items such as a messenger bag, bookbag, shopping bag (e.g. used by high-end retailers),
kitbag, handbag, schoolbag or suitcase, satchels, sling bag, postbag, duffel bag,
etc.
[0027] Moreover, for brevity only a limited number of embodiments are described in the following.
However, the skilled person will recognize that the specific features described with
reference to these embodiments can be modified and combined differently and that certain
aspects of the specific embodiments may also be omitted. Moreover, it is noted that
the aspects described in the subsequent detailed description may be combined with
aspects described in the above summary section.
[0028] Fig. 1 presents a possible embodiment of a backpack 100 according to the present
invention worn by a wearer 102 in front view, rear view and side view. According to
the first aspect of the present invention, the backpack 100 comprises a main body
105, two cushioning shoulder straps 110 adapted for cushioning a load of the main
body 105 and two pairs of stability straps 120 individually connecting a distal part
of each cushioning shoulder strap 110 to the main body 105. In general, the cushioning
shoulder strap 110 has an elongated shape with a proximal part closer to the main
body 105 and a distal part more away from the main body 105. As shown in Fig. 1, the
distal part may be referred to as a lower part of the cushioning shoulder strap 110
that is distant from the wearer's shoulder. Preferably, when the backpack 100 is worn
by the wearer 102, each of the stability straps 120 is adapted to extend below an
armpit of the wearer 102 and between an arm 103 and the body side of the wearer 102.
As a result, the main body 105 is maintained in a desired position, especially during
sports applications such as downhill biking, which provides a secure positioning of
the backpack 100 on the wearer's back.
[0029] In the context of this application, the term "main body" is understood as the part
of the backpack which contains items packed in the backpack and which is usually worn
on the wearer's back. The main body may comprise at least one compartment and / or
pocket which may be closed for storing the items.
[0030] As can be seen from the side view of the preferred embodiment in Fig. 1, an upper
stability strap 120 is connected to the main body 105 at a first stability anchorage
121a (indicated by a dashed circle in Fig. 1) which is arranged in a thorax area of
the wearer 102. In addition, a lower stability strap 120 is connected to the main
body 105 at a second stability anchorage 121b (also depicted by a dashed circle) which
is arranged in a waist area of the wearer 102. The first stability anchorage 121a
is arranged closer to a shoulder of the wearer 102 than the second stability anchorage
121b. The distance between the first stability anchorage 121a and the second stability
anchorage 121b is smaller than the distance between the first stability anchorage
121a and an upper end of the main body 105. As shown in Fig. 1, when the backpack
100 is worn on the wearer's back, the upper end of the main body 105 may be the part
of the main body that is adjacent to the wearer's shoulder. The stability anchorages
will be described in more detail with reference to Figs. 2A - 2C. It is also conceivable
to provide any other suitable arrangement of the stability anchorages on the backpack
100 in order to provide an improved secure positioning of the backpack 100 on the
wearer's back for sports applications.
[0031] In the preferred embodiment of Fig. 1, the backpack 100 further comprises a supporting
strap 150 connecting the two cushioning shoulder straps 110. It is also conceivable
that a backpack according to the invention may comprise more than one supporting strap
150 as will be described below with reference to Fig. 3. The supporting strap 150
may cooperate with the four stability straps 120 to maintain the two cushioning shoulder
straps 110 at a comfortable and secured position on the wearer's back.
[0032] In one embodiment, the cushioning shoulder straps 110 may comprise tubular knitwear.
Tubular knitwear allows for easy padding or cushioning by placing a corresponding
insert in the void formed by the tubular knitwear.
[0033] Figs.
2A - 2C present further possible embodiments of a backpack 200 according to the present invention.
Fig. 2A presents the backpack 200 in rear view, front view and side view. Fig. 2B
presents a detailed front view of the backpack 200 for explaining the second aspect
of the present invention and Fig. 2C presents a particular embodiment of the backpack
200 in side view for explaining the first aspect of the present invention.
[0034] In the preferred embodiment of Fig. 2A, the backpack 200 comprises a main body 205,
two cushioning shoulder straps 210 adapted for cushioning a load of the main body
205 and two pairs of stability straps 220 individually connecting a distal part 211
of each cushioning shoulder strap 210 to the main body 205. The arrangement of the
stability straps 220 may form a "V" shape when each of the stability straps 220 is
stretched, where the distal part 211 of the cushioning shoulder strap 210 is at the
tip of the "V" shape.
[0035] In the preferred embodiment of Fig. 2A, the stability straps 220 individually connecting
the distal part 211 of each cushioning shoulder strap 210 to the main body 205 are
provided as a single stability strap 220 extending from the main body 205 to the distal
part 211 of the cushioning shoulder strap 210 and back to the main body 205. An upper
part of the stability strap 220 is connected to the main body 205 at a first stability
anchorage 221a and a lower part of the stability strap 220 is connected to the main
body 205 at a second stability anchorage 221b. The first stability anchorage 221a
and second stability anchorage 221b may be arranged similar to the above described
embodiment shown in Fig. 1, e.g. at the thorax and the waist area of a wearer wearing
the backpack 200.
[0036] As can be seen in Fig. 2A, the backpack 200 also comprises two pairs of coupling
straps 230 individually connecting a proximal part 212 of each cushioning shoulder
strap 210 with the main body 205. Similarly, the cushioning shoulder strap 210 has
an elongated shape with a proximal part 212 closer to the main body 205 and a distal
part 211 more away from the main body 205. As shown in Fig. 2A, the proximal part
212 of the cushioning shoulder strap 210 may be referred to as an upper part of the
cushioning shoulder strap 210 that is adjacent to the wearer's shoulder. The coupling
straps 230 are adapted to adjust the position of the proximal part 212 of each cushioning
shoulder strap 210. Moreover, the coupling straps 230 may be adapted to adjust the
position of the proximal part 212 of each shoulder strap in a lateral direction which
is orthogonal to the longitudinal extension of each cushioning shoulder strap 210.
[0037] Furthermore, each of the coupling straps 230 may be connected to the main body at
a first and a second coupling anchorage (not shown in Fig. 2A). Preferably, at least
one of the coupling anchorages is arranged on an inner surface of the main body 205.
The arrangement of the coupling straps 230 may also form a "V" shape when each of
the coupling straps 230 is stretched, where the proximal part 212 of the cushioning
shoulder strap 210 is at the tip of the "V" shape. The coupling straps 230 and their
anchorages will be further described in more detail in Fig. 2B.
[0038] The main body 205 and at least one of the different straps may be at least partially
manufactured by various techniques in order to achieve desired characteristics or
functions including bendability, stretchability (expressed as Young's modulus, for
example), permeability to air/breathability and water, thermoconductivity, thermal
capacity, moisture absorption, static friction, abrasion resistance, reinforcement,
hardness and thickness, etc. Permeability to air and breathability can for example
be achieved by knitting a more open mesh- or web-like structure. For example by using
knitting techniques (e.g. weft-knitted fabrics, single-thread warp-knitted fabrics,
warp-knitted fabrics, three-dimensional knitting, functional knitting, etc.), this
may include the selection of fibers and yarns, coating the fibers, yarns or knitwear
with polymer or other materials, the use of monofilaments, the combination of monofilaments
and polymer coating, the application of fusible/melted yarns, and multi-layer textile
material. In general, the yarns used for the manufacture of knitwear may be quipped,
i.e. coated accordingly. Additionally or alternatively, the finished knitwear may
be equipped accordingly. It is also conceivable to use any other suitable techniques
as known by the person skilled in the art.
[0039] The main body 205 may comprise at least one area which is coated. The coating may
for example provide water-repellency or abrasion-resistance. The area may be coated
with a thermoplastic polyurethane, TPU, coating. TPU is rather easy to handle and
to apply. Additionally or alternatively, the area may be coated with ultraviolet,
UV, glue. UV glue may be applied in liquid form and cures under UV light by a photochemical
process. In general, other coatings may be used as well.
[0040] Moreover, the main body 205 and at least one of the different straps may comprise
a flexible material, preferably from a waterproof material and particularly preferred
from a plastic fabric, e.g. Cordura®. Parts of the main body may also comprise a rigid
or a bendable hard material. Additionally or alternatively, the main body 205 may
comprise different regions having different materials, for example the regions 206,
which may comprise suitable fabrics for reinforcement of the main body 205.
[0041] The stability anchorages 221a, 221b and / or the coupling anchorages may comprise
at least one of the following: sewing, a buckle, a ring, or any type of connecting
or fastening element that is feasible to connect and attach the different straps to
the main body 205.
[0042] The backpack 200 further comprises a supporting strap 250 connecting the two cushioning
shoulder straps 210. The supporting strap 250 may function in the same way as supporting
strap 150 described above.
[0043] In one embodiment, the shoulder straps 210 may comprise a convex shape, which is
adapted to go around a wearer's breast, e.g. if the wearer is a woman. The shoulder
straps 210 with the convex shape can cooperate with the stability straps 220, the
coupling straps 230 and the supporting straps to provide an optimized position of
the shoulder straps around a wearer's body and thus a comfortable wearing experience
of the backpack 200.
[0044] In a still further embodiment, the distal or lower part of the at least one cushioning
shoulder strap 210 may be arranged on a front torso area of the wearer.
[0045] As can be seen in Fig. 2A, the backpack 200 may further comprise at least one handle,
e.g. one handle 255. This allows the backpack 200 to be easily carried with a single
hand. The handle 255 may be knitted in one piece with the main body 205 of the backpack
200. In this way, additional manufacturing steps of producing the handle 255 and attaching
it to the backpack 200 are omitted. The additional efforts and costs for providing
the handle 255 are reduced.
[0046] Furthermore, the backpack 200 may comprise a back panel 260. It is also conceivable
that the backpack may further comprise at least one additional panel such as a front
panel, one or more side panels which may form and / or reinforce the main body 205.
[0047] In one embodiment, at least one of the anchorages may be arranged on the back panel
260 of the backpack 200. Additionally or alternatively, the anchorages may be arranged
at the edge between the back panel 260 and one side panel of the backpack. Moreover,
the back panel 260 may comprise at least one protrusion or opening 270, which may
provide a better breathability of the wearer's back. Additionally or alternatively,
the back panel 260 may comprise at least some areas covered by a cushion material,
which provide more comfortability for a wearer of the backpack 200.
[0048] As can be seen in Fig. 2A, the backpack 200 comprises three zippers 280 for closing
parts or pockets of the main body 205. Instead of a zipper 280, other means of closing
the main body 205 may be used, such as a snap button, a hook-and-loop fastener or
a magnetic closure. The main body 205 could also comprise no closure mechanism.
[0049] Fig.
2B presents a detailed view of the coupling straps 230 of the backpack 200. Parts of
the main body 205 are removed so that the main body 205 shown in this figure only
comprises the back panel 260.
[0050] As can be seen in Fig. 2B, the backpack 200 comprises a first and a second pair of
coupling straps 230, wherein the first pair is connected to a proximal part of a first
cushioning shoulder strap 210 (e.g. the left one) and to the back panel 260 and the
second pair is connected to a proximal part of a second cushioning shoulder strap
210 (e.g. the right one) and to the back panel 260.
[0051] As mentioned above, the coupling straps 230 individually connect a proximal part
212 of each cushioning shoulder strap 210 with the back panel 260, wherein the coupling
straps 230 are adapted to adjust the position of the proximal part 212 of each cushioning
shoulder strap 210. In particular, the coupling straps 230 may be adapted to adjust
the position of the proximal part 212 of each shoulder strap in a lateral direction
(indicated by the two double arrows) which is essentially orthogonal to the longitudinal
extension (indicated by the dashed arrow) of each cushioning shoulder strap 210. The
coupling straps 230 can be adjusted, for example by adjusting at least one length
of one of the coupling straps 203.
[0052] Moreover, with respect to each cushion shoulder strap 210, the at least two coupling
straps 230 may be provided as a single strap extending from the main body 205 to the
proximal part 212 of each cushioning shoulder strap 210 and back to the main body
205. For example, the coupling straps 230 (e.g. the left ones) may be connected to
the main body at a first coupling anchorage (not shown in Fig. 2B) and a second coupling
anchorage 231. As shown in Fig. 2B, the main body 205 may further comprise at least
one aperture, such that the coupling straps 230 extends through the aperture and connects
to the main body at the second coupling anchorage 231, which is arranged on the back
panel 260 and on an inner surface of the main body 205. As mentioned above, such a
construction reduces manufacturing costs and allows for an easier adjustment of the
coupling straps, e.g. tightening.
[0053] Moreover, a coupling strap 230 of the first pair may be connected to a coupling strap
230 of the second pair, wherein the connection may be arranged on an inner surface
of the main body 205, e.g. on an inner side of the back panel 260. As mentioned above,
such an arrangement facilitates the manufacture and the adjustment of the fit, as
only a reduced number of couplings straps 230 must be adjusted.
[0054] In the preferred embodiment of Fig. 2B, the second coupling anchorage 231 is provided
as a buckle and by sewing, and the coupling strap 230 is connected to the proximal
part of the cushioning shoulder strap 210 via a ring, so that the length of the coupling
strap 230 is flexibly adjustable.
[0055] Fig. 2C presents a particular embodiment of the backpack 200 in side view according
to the first aspect of the present invention.
[0056] As mentioned above, the stability straps 220 individually connecting the distal part
211 of each cushioning shoulder strap 210 to the main body 205 are provided as a single
stability strap 220 extending from the main body 205 to the distal part 211 of the
cushioning shoulder strap 210 and back to the main body 205.
[0057] The stability strap 220 is connected to the main body 205 at a first stability anchorage
221a and at a second stability anchorage 221b. Here the stability anchorages 221a
and 221b comprise sewing of the stability strap 220 to the main body 205, and the
stability strap 220 is connected to the distal part of the cushioning shoulder strap
210 via a ring. A buckle is positioned at the second stability anchorage 221b. By
such an arrangement, the length of the stability strap 220 is adjustable through the
buckle and the ring. For example, the stability strap 220 may slide through the ring,
and the lower part of the stability strap 220 may be longer or shorter than the upper
part of the stability strap.
[0058] The first stability anchorage 221a and second stability anchorage 221b may be arranged
with respect to a longitudinal direction of the backpack 200. In the embodiment shown
in Fig. 2A, the stability anchorages 221a, 221b are at a lower portion of the backpack
200 and are vertically spaced from each other. The first stability anchorage 221a
is closer to an upper end of the backpack, which may be adjacent to a wearer's shoulder
during use. The second stability anchorage 221b is more distant from the upper end
of the backpack.
[0059] The first stability anchorage 221a and second stability anchorage 221b may again
be arranged in the thorax and the waist area of a wearer of the backpack 200, so that
they extend below an armpit of a wearer and between an arm and the body side of the
wearer of the backpack 200 to maintain the main body 205 in a desired position.
As can be seen in Fig. 2C, the backpack 200 may further comprise a waist belt 290
for securely positioning the backpack 200 on a wearer's back and waist. The waist
belt 290 may further comprise a means for closing similar to the supporting strap
250 as mentioned above.
[0060] Fig.
3 presents a further possible embodiment of a backpack 300 according to the present
invention in front and side view. The backpack 300 may comprise similar features as
the backpacks 100 and 200 as shown in Figs. 1 - 2C.
[0061] In the preferred embodiment of Fig. 3, the two cushioning shoulder straps 310 comprise
a cushioning mesh material. Such an embodiment provides a better breathability for
a wearer of the backpack 300 and is advantageous for sports applications, such as
for use in higher temperatures. Additionally or alternatively, the back panel of the
main body may also comprise a mesh.
[0062] Moreover, the backpack 300 comprises two supporting straps 350 to cooperate with
the stability straps 320 to maintain the two cushioning shoulder straps 310 at a comfortable
position on a wearer's back. For example, the distance between the cushioning shoulder
straps 310 may be increased when a wearer adjusts the length of at least one of the
stability straps 320, such that the cushioning shoulder straps 310 are no longer close
to each other. In this case, the supporting straps 350 may be adjusted to provide
a proper distance of the two cushioning shoulder straps 310 and thus to maintain an
optimized position of the backpack on a wearer's back.
[0063] In the following, further embodiments are described to facilitate the understanding
of the invention:
- 1. A backpack (100; 200; 300) comprising:
- a. a main body (105; 205);
- b. at least one cushioning shoulder strap (110; 210; 310); and
- c. at least two stability straps (120; 220; 320) individually connecting a distal
part (211) of the at least one cushioning shoulder strap (110; 210; 310) to the main
body (105; 205).
