FIELD
[0001] The present disclosure relates to the field of safety systems for vehicles. More
specifically, the present disclosure relates to a safety system configured to prevent
unintentional opening of a door of a vehicle when an impact is sustained by the door
of the vehicle.
BACKGROUND
[0002] A door of a vehicle typically includes an outside handle configured to allow a user
of the vehicle to open the door of the vehicle. Additionally, the door of the vehicle
typically includes a door lock which is configured to keep the door of the vehicle
closed until the user employs the outside handle to open the door of the vehicle.
Between the outside handle and the door lock is a connection which is configured to
transfer input from the outside handle and/or the user to the door lock, thereby allowing
the door to be opened. The connection between the outside handle and the door lock
is typically a physical connection or an electronic connection. For physical connections,
a door locking rod may extend between the outside handle and the door lock. Upon an
impact sustained by the door of the vehicle in a crash, an outer panel of the door
of the vehicle may be deformed, which may displace the door locking rod and trap the
door locking rod between the outer panel of the door and a surrounding part within
the door of the vehicle. Displacing and trapping the door locking rod may cause unintentional
opening of the door, thereby creating an unsafe condition.
[0003] Many vehicles may include a rotating counterweight attached to the door locking rod
which is configured to prevent the outside handle from self-opening the door when
an impact is sustained by the door of a vehicle. However, due to local panel deformations
of the door, as well as many possible deformation modes (such as those caused by different
heights of vehicles from the ground), predicting exact forces and acceleration that
will locally influence the outside handle when an impact is sustained by a door is
difficult. Therefore, the counterweight may not always function as expected. Additionally,
even with use of the counterweight, the door locking rod may still be trapped between
the outer panel of the door and a surrounding part, causing unintentional opening
of the door when an impact is sustained by the door.
[0004] Currently available safety systems, such as that disclosed by German Patent Application
No.
DE102008011754 may include installing a heavy, metal part which is attached to the outer panel of
the door of the vehicle and configured to only protect the outside handle when an
impact is sustained by a door of a vehicle. Protecting only the outside handle does
not effectively prevent the door locking rod from being trapped when an impact is
sustained by the door of the vehicle. Additionally, using separate, heavy parts increases
the weight and manufacturing costs associated with implementing the safety system.
[0005] It is desirable to provide a lightweight, cost-efficient safety system configured
to prevent a door locking rod of a door locking system from being trapped between
an outer panel of a door of a vehicle and a surrounding part within the door of the
vehicle, in order to prevent unintentional opening of the door of the vehicle when
an impact is sustained by the door of the vehicle.
SUMMARY
[0006] According to aspects of the disclosure, a spacer for a door locking system of a door
of a vehicle is presented, the door locking system includes a handle, a handle frame,
and a door locking rod, and the spacer comprises a body having a first end and a second
end, the body is configured to extend between the handle frame and a glass lower frame
arranged within the door of the vehicle, and wherein, the second end of the body is
capable of contacting the glass lower frame to maintain spacing between the handle

DETAILED DESCRIPTION
[0014] An embodiment of a safety (spacing) system and an outside handle spacer (referred
to herein as a "spacer") according to aspects of the disclosure will now be described
with reference to Figures 1-6. Like numerals represent like parts, and the safety
system and the spacer will generally be referred to by the reference numerals 10 and
20, respectively. Although the safety system 10 and the spacer 20 are described with
reference to specific examples, it should be understood that modifications and changes
may be made to these examples without going beyond the general scope as defined by
the claims. In particular, individual characteristics of the various embodiments shown
and/or mentioned herein may be combined in additional embodiments. Consequently, the
description and the drawings should be considered in a sense that is illustrative
rather than restrictive. The Figures, which are not necessarily to scale, depict illustrative
aspects and are not intended to limit the scope of the disclosure. The illustrative
aspects depicted are intended only as exemplary.
[0015] The term "exemplary" is used in the sense of "example," rather than "ideal." While
aspects of the disclosure are amenable to various modifications and alternative forms,
specifics thereof have been shown by way of example in the drawings and will be described
in detail. It should be understood, however, that the intention is not to limit aspects
of the disclosure to the particular embodiment(s) described. On the contrary, the
intention of this disclosure is to cover all modifications, equivalents, and alternatives
falling within the scope of the disclosure.
[0016] Various materials, methods of construction and methods of fastening will be discussed
in the context of the disclosed embodiment(s). Those skilled in the art will recognize
known substitutes for the materials, construction methods, and fastening methods,
all of which are contemplated as compatible with the disclosed embodiment(s) and are
intended to be encompassed by the appended claims.
[0017] As used in this disclosure and the appended claims, the singular forms "a," "an,"
and "the" include plural referents unless the content clearly dictates otherwise.
As used in this disclosure and the appended claims, the term "or" is generally employed
in its sense including "and/or" unless the content clearly dictates otherwise.
[0018] Throughout the description, including the claims, the terms "comprising a," "including
a," and "having a" should be understood as being synonymous with "comprising one or
more," "including one or more," and "having one or more" unless otherwise stated.
In addition, any range set forth in the description, including the claims should be
understood as including its end value(s) unless otherwise stated. Specific values
for described elements should be understood to be within accepted manufacturing or
industry tolerances known to one of skill in the art, and any use of the terms "substantially,"
"approximately," and "generally" should be understood to mean falling within such
accepted tolerances.
[0019] When an element or feature is referred to herein as being "on," "engaged to," "connected
to," or "coupled to" another element or feature, it may be directly on, engaged, connected,
or coupled to the other element or feature, or intervening elements or features may
be present. In contrast, when an element or feature is referred to as being "directly
on," "directly engaged to," "directly connected to," or "directly coupled to" another
element or feature, there may be no intervening elements or features present. Other
words used to describe the relationship between elements or features should be interpreted
in a like fashion (e.g., "between" versus "directly between," "adjacent" versus "directly
adjacent," etc.).
[0020] Spatially relative terms, such as "top," "bottom," "middle," "inner," "outer," "beneath,"
"below," "lower," "above," "upper," and the like, may be used herein for ease of description
to describe one element or feature's relationship to another element(s) or feature(s)
as illustrated in the drawings. Spatially relative terms may be intended to encompass
different orientations of a device in use or operation in addition to the orientation
depicted in the drawings. For example, if the device in the drawings is turned over,
elements described as "below" or "beneath" other elements or features would then be
oriented "above" the other elements or features. Thus, the example term "below" can
encompass both an orientation of above and below. The device may be otherwise oriented
(rotated 90 degrees or at other orientations) and the spatially relative descriptors
used herein interpreted accordingly.
[0021] Although the terms "first," "second," etc. may be used herein to describe various
elements, components, regions, layers, sections, and/or parameters, these elements,
components, regions, layers, sections, and/or parameters should not be limited by
these terms. These terms are only used to distinguish one element, component, region,
layer, or section from another region, layer, or section. Thus, a first element, component,
region, layer, or section discussed herein could be termed a second element, component,
region, layer, or section without departing from the teachings of the present disclosure.
[0022] As shown in Figures 1-6, the safety system 10 and the spacer 20 may be configured
to prevent unintentional opening of a door 100 of a vehicle (not shown) due to impact
sustained by the door 100 of the vehicle. Referring to Figure 3, the door 100 of a
vehicle includes an outer panel 102 and an inner panel 104. It is contemplated that
the terms "outer" and "inner" as used herein may be understood with reference to an
interior of a vehicle, such that the outer panel 102 is at and/or closer to an exterior
(outside) of the vehicle and the inner panel 104 is at and/or closer to the interior
(inside) of the vehicle. Additionally, the door 100 includes a window (not shown).
As such, glass is arranged between the outer panel 102 and the inner panel 104 of
the door 100. As shown in Figures 2-3, the glass is held and/or positioned within
the door 100 by a glass lower frame (also referred to herein as a "support") 115.
As such, the glass lower frame 115 is arranged between the outer panel 102 and the
inner panel 104 of the door 100. It is contemplated that the term "lower" as used
herein may be understood to mean a position at which the glass is supported, and/or
a position at which the glass lower frame 115 is positioned with respect to the glass.
As shown in Figures 2-3, the glass lower frame 115 extends substantially parallel
to the outer panel 102 and the inner panel 104 of the door 100. The glass lower frame
115 may be configured to translate in an upward direction and a downward direction
due to opening and closing of the window. It is contemplated the terms "upward" and
"downward" may be understood with reference to a vehicle, such that the upward direction
is toward a roof of the vehicle and the downward direction is toward a surface beneath
the vehicle.
[0023] The door 100 is configured to move between an open condition and a closed condition.
As shown in Figure 1, the door 100 includes a door locking system 110 configured to
maintain the door 100 in the closed condition, and to allow a user to move the door
100 to the open condition. Referring to Figures 1-3 of the disclosed embodiment, the
door locking system 110 includes an outside handle (referred to herein as a "handle")
120 configured to receive input from a user to move the door 100 to the open condition;
an outside handle frame (referred to herein as a "handle frame") 140 configured to
support the handle 120; a door lock 160 configured to transition from a locked state
(first position) to an unlocked state (second position), in order to enable movement
of the door 100 to the open condition, and from the unlocked state to the locked state,
in order to maintain the door 100 in the closed condition; and a door locking rod
180 configured to transmit the input from the handle 120 to the door lock 160 to move
the door 100 to the open condition. The door locking system 110 is configured to function
between the outer panel 102 and the inner panel 104 of the door 100. The spacer 20
is configured to function in combination with the door locking system 110 as part
of the safety system 10. Additionally or alternatively, it is contemplated that the
spacer 20 is configured to be incorporated by the door locking system 110 as part
of the safety system 10. Additionally or alternatively, it is contemplated that the
safety system 10 may correspond to a combination of the handle frame 140 and the spacer
20 (see Figure 4). In this manner, the safety system 10 and the spacer 20 are configured
to prevent the door 100 from opening unintentionally due to an impact sustained by
the door 100.
[0024] As shown in Figures 1-3, the handle 120 may be positioned at an outer wall of the
outer panel 102 of the door 100. In the disclosed embodiment, the handle 120 is connected
to and/or supported by the handle frame 140. The handle frame 140 may be attached
to and/or extend through the outer panel 102 of the door 100. Additionally or alternatively,
the handle frame 140 may be attached to an inner wall of the outer panel 102 (see
Figures 2-3). As shown in Figure 3, at least a portion of the handle frame 140 is
positioned between the outer panel 102 and the inner panel of the door 100. The handle
frame 140 may be constructed of a polymeric material. In the disclosed embodiment,
the handle frame 140 is constructed of a plastic material. However, it is contemplated
that a person having ordinary skill in the art that would appreciate that the handle
frame 140 may be constructed of any other alternative material which may be compatible
with the safety system 10 and/or the spacer 20. Additionally, it is contemplated that
an alternative material may be compatible with the safety system 10 and/or the spacer
20 if the alternative material is durable, lightweight, and/or is capable of being
formed integrally with the spacer 20. As shown in Figures 1-2, the handle 120 is connected
to the door locking rod 180. Additionally or alternatively, the handle 120 may be
connected to a counterweight, which is connected to the door locking rod 180, to prevent
self-opening by the handle 120. Additionally, the door locking rod 180 is connected
to the door lock 160. As such, the door locking rod 180 is configured to transmit
input from the user to the door lock 160. In this manner, the handle 120 and the door
locking rod 180 are configured to transition the door lock 160 to the unlocked state
to move the door 100 from the closed condition to the open condition.
[0025] The door lock 160 may be attached to the inner panel 104 of the door 100. Referring
to Figures 1-3, the glass lower frame 115 extends between the door lock 160 and the
door locking rod 180. As such, referring to Figure 3, the door locking rod 180 extends
between the glass lower frame 115 and the outer panel 102 of the door 100. Additionally,
the door locking rod 180 extends between the glass lower frame 115 and the handle
frame 140. The door locking rod 180 extends downwardly beneath the spacer 20.
[0026] As shown in Figures 3-4, the spacer 20 is configured to extend between the glass
lower frame 115 and the handle frame 140. As such, the spacer 20 extends between the
glass lower frame 115 and the outer panel 102 of the door 100. In the disclosed embodiment,
the spacer 20 is attached to the handle frame 140. As such, the spacer 20 is distanced
from the outer panel 102 of the door 100 by the handle frame 140. In the disclosed
embodiment, the spacer 20 is integrally formed with the handle frame 140, such that
the spacer 20 and the handle frame 140 may be manufactured as one part. The spacer
20 is constructed of a rigid material, such that the spacer 20 may withstand force
exerted on the spacer 20 when the outer panel 102 of the door 100 sustains an impact.
In the disclosed embodiment, the spacer 20 is constructed of the same material as
the handle frame 140. As such, the spacer 20 is constructed of a polymeric material.
Preferably, the spacer 20 is constructed of a plastic material. However, it is contemplated
that a person having ordinary skill in the art that would appreciate that the spacer
20 may be constructed of any other alternative material which may be compatible with
the safety system 10 and/or the handle frame 140. Additionally, it is contemplated
that an alternative material may be compatible with the safety system 10 and/or the
handle frame 140 if the alternative material is durable, lightweight, and/or is capable
of being formed integrally with the handle frame 140. Constructing the spacer 20 of
a polymeric material, preferably a plastic material, allows the spacer 20 to be lightweight.
Additionally, since the handle frame 140 is also constructed of a polymeric material,
preferably a plastic material, the spacer 20 only adds a small increase in weight
to the handle frame 140, thus making the safety system 10 lightweight. Additionally,
manufacturing the handle frame 140 and the spacer 20 as one integral part, rather
than separate components, allows for manufacture and/or addition of the spacer 20
to be cost-efficient. In this manner, manufacturing the handle frame 140 and the spacer
20 as one integral part, rather than separate components, allows for the safety system
10 to be lightweight and cost-efficient.
[0027] As shown in Figure 2-4, the spacer 20 includes a body 22 extending between a first
end 24 and a second end 26. In the disclosed embodiment, the first end 24 of the body
22 of the spacer 20 is attached to and/or integrally formed with the handle frame
140. Additionally, the second end 26 of the body 22 of the spacer 20 is positioned
adjacent the glass lower frame 115. As such, the spacer 20 extends from the handle
frame 140 toward the glass lower frame 115. In this manner, the spacer 20 is configured
and/or positioned to overlap and/or align with the glass lower frame 115 (see Figure
4), so that the spacer 20 may contact the glass lower frame 115 when an impact is
sustained by the door 100. Alternatively, it is contemplated that first end 24 of
the body 22 of the spacer 20 may be attached to and/or integrally formed with the
glass lower frame 115, such that the spacer 20 extends from the glass lower frame
115 toward the handle frame 140. The body 22 of the spacer 20 may have a length which
allows the spacer 20 to maintain sufficient distance between the outer panel 102 of
the door 100 and the glass lower frame 115 when the door 100 sustains an impact. In
the disclosed embodiment, the body 22 of the spacer 20 is formed in the shape of a
post. It is contemplated that forming the spacer 20 in the shape of a post allows
for the spacer 20 to maintain sufficient distance between the outer panel 102 of the
door 100 and the glass lower frame 115, while using less material to manufacture the
spacer 20 and occupying less space within the door 100. However, it is contemplated
that a person having ordinary skill in the art that would appreciate that the spacer
20 may formed in any shape which may be compatible with the safety system 10. Additionally,
it is contemplated that an alternative shape may be compatible with the safety system
10 if the alternative shape is capable of maintaining spacing and/or a distance between
the outer panel 102 of the door 100 and the glass lower frame 115 when the door 100
sustains an impact.
[0028] As illustrated by Figure 5, which does not include the safety system 10 and/or the
spacer 20, due to the positioning of the door locking rod 180 between the glass lower
frame 115 and the outer panel 102 of the door 100 and/or the handle frame 140, the
door locking rod 180 may get trapped (pinched) between the glass lower frame 115 and
the outer panel 102 of the door 100 and/or the handle frame 140 as a result of impact
sustained by the door 100. It is contemplated that the term "impact" as used herein
may be understood to mean force exerted and/or a load acting on the outer panel 102
of the door 100 which causes the outer panel 102 to be deformed. Additionally, it
is contemplated that the force exerted and/or load acting on the outer panel 102 of
the door is in a direction of the glass lower frame 115. Deformation of the outer
panel 102 may cause the outer panel 102 to move closer to the glass lower frame 115
and thus displace the door locking rod 180 and/or trap the door locking rod 180 against
the glass lower frame 115. Displacement of the door locking rod 180 and trapping the
door locking rod 180 against the glass lower frame 115 may cause the door lock 160
to transition to the unlocked state and be maintained in the unlocked state, unintentionally
moving the door 100 to the open condition. As shown in Figure 6, under "normal/desired
behavior" of the door locking rod 180 when an impact has been sustained by the door
100, the door lock 160 is not maintained in the unlocked state due to momentary displacement
of the door locking rod 180, and the door 100 is not able to move into the open condition.
However, under "actual behavior" of the door locking rod 180 when an impact has been
sustained by the door 100, the door locking rod 180 is displaced and trapped between
the glass lower frame 115 and the outer panel 102 of the door 100, the door lock 160
is maintained in the unlocked state, and the door 100 unintentionally moves into the
open condition.
[0029] In operation, the spacer 20, and thus the safety system 10, is configured to prevent
the door locking rod 180 from being trapped between the glass lower frame 115 and
the outer panel 102 of the door 100. To prevent the door locking rod 180 from being
trapped between the glass lower frame 115 and the outer panel 102 of the door 100,
the spacer 20 is configured to contact the glass lower frame 115 when the outer panel
102 of the door 100 is deformed, as the handle frame 140 and the spacer 20 and/or
the outer panel 102 of the door 100 move closer to the glass lower frame 115 when
an impact is sustained by the door 100. In the disclosed embodiment, contact between
the spacer 20 and the glass lower frame 115 maintains spacing and/or a distance between
the outer panel 102 of the door 100 and the glass lower frame 115 when an impact is
sustained by the door 100. Additionally or alternatively, the spacer 20 may be configured
to transfer the force exerted and/or the load acting on the outer panel 102 of the
door 100 to the glass lower frame 115 to deform the glass lower frame 115 when an
impact is sustained by the door 100. As such, it is contemplated that the spacer 20
contacts the glass lower frame 115 and may deform the glass lower frame 115 due to
and/or with the impact sustained by the door 100 (the force exerted and/or the load
acting on the outer panel 102 of the door 100 in the direction from the spacer 20
to the glass lower frame 115). It is contemplated that deforming the glass lower frame
115 also maintain spacing and/or a distance between the outer panel 102 and the glass
lower frame 115. Maintaining spacing and/or a distance between the outer panel 102
of the door 100 and the glass lower frame 115 ensures that the door locking rod 180
is not trapped between the outer panel 102 and the glass lower frame 115. As such,
the door locking rod 180 is free to move between the outer panel 102 and the glass
lower frame 115 when an impact is sustained by the door 100. In this manner, the door
lock 160 is prevented from being maintained in the unlocked state, as the door locking
rod 180 can no longer be trapped between the glass lower frame 115 and the outer panel
102 when an impact is sustained by the door 100, thereby preventing the door 100 from
unintentionally moving to the open condition.
