The present invention relates to an inflatable device for personal protection and to a garment comprising the same.
During the last years, after a constant search for safety during all sports activities, but more in general also all those dangerous activities as made under extreme conditions or at high speeds, a plurality of devices both for the person's active and passive safety has been devised.
The motorcycle field pays particularly attention to such problems and, therefore, during the last years, it has been searching for the development of an airbag system allowing to implement a motorcyclist's effective protection which has also to be practical.
The most practical solution has revealed to be the use of garments which can be inflated in case of impact, slide or fall in general.
Therefore, a plurality of garments has been developed, comprising one or more bags which can be inflated by means of cylinders of different types of cold gas which activate in case of impact.
However, the garments of known art do not reveal to be sufficiently effective and practical in protecting the driver, in particular during the use in the sports competitions.
The protection, in fact, is provided by inflatable members fastened to the garment and, when deflated, put inside specific pockets, which, apart from inflating in sufficiently short time, have also to protect, when inflated, the body parts which are potentially involved by the impacts. Furthermore, other important features relate to the overall dimensions which have to be kept limited as a whole, as it is advisable that the garment be practical during the normal use.
In fact, it must be understood that the bags and the related inflating means are worn by the user and such components have not negligible sizes and weights in case of use during the competitions.
In the motorcyclist races, in fact, the drivers use suits which must have high aerodynamic penetration features and consequently the use of inflatable members has not to jeopardize the driver's performances in any way, nor be cause of discomfort for the same.
Furthermore, one of the main causes for which the inflatable garments have never found application in the motorcyclist races is related to the fact that often the drivers, even after ruinous falls, succeed in rising again and continuing the race. However, it is clear that the garment, once inflated, does not allow the driver to continue the race any more, as it is excessively bulky and it makes the driver's motions pratically impossible.
Therefore, the technical problem underlying the present invention is to provide an inflatable protective garment allowing to obviate the drawbacks mentioned above by referring to the known art.
Such problem is solved by an inflatable device for personal protection according to claim 1 and by a garment according to claim 23.
The present invention provides some important advantages. The main advantage lies in the fact of providing an inflatable device which can be placed so as to allow an effective protection of the user without limiting the mobility and the aerodynamic properties of the garment. Furthermore, even in case of opening after falling or other event, the device according to the present invention can be removed so as to allow the driver to continue the race without particular discomforts.
Other advantages, features and application modes of the present invention will be made evident by the following detailed description of some embodiments thereof, shown by way of example and not for limitative purpose. The figures of the enclosed drawings will be referred to wherein:
By firstly referring to
In such configuration, the inflatable member 1 is filled-up with air or other gas so as to provide protection and defence to the body of a user in case of fall, slide or impact. According to a preferred embodiment, and as it will be illustrated hereinafter in detail, the inflatable member 1 comprises a rear portion 11, apt to protect the upper part of the user's back, portions 12 protecting the shoulders and partially the arms, portions 13 arranged between shoulders and neck for protecting the latter and portions 14 apt to protect an upper area of the chest, illustrated according to different views in
Such portions allow to protect the body parts which are more exposed to the risk of trauma during impacts and falls occurring in the motorcyclist practice, considering that the garments used by the drivers in the races have specific back-guards so as to require just the protection of the upper part of the back and neck by means of the inflatable member.
In order to implement the inflation of the inflatable member 1 in case of fall and/or slide and/or impact by an user or a vehicle whereon he/she proceeds, the device according to the present invention is apt to cooperate with specific activation and inflation means, not illustrated in figure.
Such means can comprise cylinders of compressed gas or gas generators of pyrotechnical or hybrid type or other typologies known to the state of art. Said inflation means is controlled by a control unit based upon the detection of the state of the vehicle/driver system; for example, said control unit can implement a system for predicting the fall allowing a timely identification of the fall event and a reliable prediction thereof by means of accelerometric sensors integral to the vehicle (or to the driver) and a processing unit of the signals produced by the sensors themselves. As an alternative, the device according to the present invention finds also application by using an activation wire connected to the vehicle, which controls the inflation of the inflatable member after moving away the user from the vehicle, for example after a fall or an impact.
Anyhow, the abovementioned activation and inflation means can be integrated in the device according to the present invention or placed outside the same.
It is also to be noted that, even if the activation modes are an aspect of particular importance for an effective operation of the device, they will not be described hereinafter in greater details as they are mainly already known methods, at least in the simplest embodiments, to the person skilled in the art.
Still according to a preferred embodiment, the inflatable member 1 has a bag-like shape and it is implemented by a single body whereon the previously-described portions 11, 12, 13 and 14 are defined, so as to make simpler and more effective the inflating operation. However, also in this case the inflation member can be implemented in several parts distinct therebetween or, in case, a higher number of inflation members can be provided to protect different areas of the user's body.
By then referring to
The containing means 2 substantially comprises a pocket having an edge 24 which can be opened and which, during the normal use of the device, is kept closed by means of specific closing means 25.
In other words, according to the present embodiment, the closing means 25 allows to keep the edge 24 in contact with the remaining part of the containing means 2, so as to define a pocket wherein the inflatable member 1 is housed.
Such closing means 25 is then implemented so as to give way after the inflation of the inflatable member 1 and after the consequent pushing action produced by the member 1 during the inflation step.
The closing means 25 will be then calibrated so as to release the edge 24 under such action and to allow, at the same, the outcoming of the inflatable member 1 from the containing means 2.
By way of example, the closing means 25 could be implemented by means of snap fasteners, as in the present embodiment, or by means of seams using threads having a calibrated breakdown tension, or, moreover, by means of closing devices including members made of Velcro®.
Still by referring to
Such configuration reveals to be particularly advantageous as it has to be understood that the suits usually utilized by the drivers have an appendix with aerodynamic functions in the same area wherein the portion 20 is placed at the upper part of the back.
Therefore, the device according to the present invention, once connected to a garment, allows the containing means on the one hand to play the same aerodynamic function of the usual motorcycling suits and on the other hand to house the inflatable member 1 in a position which is not uncomfortable to the user.
Consequently, the portion 20 defines an aerodynamic appendix 20 shaped like a "hump", in a way analogous to what usually existing in the suits utilized by the motorcycling drivers.
It is also to be noted that the aerodynamic appendix has dimensions which can be sufficient also to contain the activation and inflation means, with additional advantage in the device size.
In order to obtain a more effective protection of the user, still after the connection of the device to the garment, the containing means is arranged, as previously mentioned, also at shoulders and upper part of the chest, so as to allow the outcoming from such areas of the portions 13 and 14 of the inflation member 1, to cover neck and chest.
However, it is clear that, according to a preferred embodiment, the inflation member 1 is folded up so as to be arranged inside the containing means by occupying less room as possible, considering that the greatest part of the room usable to house the member 1 is present at the portion 20.
By now referring to
According to a preferred embodiment, the connection means 3 allows to remove the containing means 2 and, together therewith, also the inflatable member 1, as the latter is fastened thereto.
In fact, it can be preferred to fasten the inflatable member 1 to the containing means 2 in a steady way, both to avoid that in case of fall the inflatable member detaches, thus wholly losing the effectiveness, and as the reversible connection means 3 requires a greater implementation complexity; in this case, then, it can be preferred to avoid that said reversible connection means 3 be directly connected to the inflatable member 1.
In other words, the inflatable member 1 is fastened to the containing means 2, which in turn can be connected, in reversible way, to the garment 4, by means of the abovementioned connection means 3.
In this way, the inflatable member could be positioned in the previously described way and removed, together with the containing means in case of need.
By referring to
According to a preferred embodiment, the loops have the shape of small pipes, inside thereof a filiform member is inserted.
Furthermore, the loops 32 are positioned substantially along the device perimeter, whereas the loops 33 are placed onto the garment so that, by placing each pair of loops 32 and 33 alternated side by side and by inserting therein the elongated member 31, the device be arranged in the previously described way and the connection of the inflatable member 1 to the garment 4 be implemented. Furthermore, the elongated member 31 can be pulled out of said loops so that, when it is pulled by the user, it can be removed, by consequently removing the device too, or at least the inflatable member 1, from the garment 4.
In this way, it will be possible to remove the inflatable member with a simple and quick operation, so as to allow the driver to continue the race without any inconvenience in case he/she has not suffered any consequence after the fall. However, it is clear that the reversible connection means 3 could be replaced by any equivalent means which allows the positioning of the inflatable member and the subsequent removal thereof.
Similarly to what previously described, also in this case the inflatable member 101 in an inflated configuration has a rear portion 111, arranged onto the upper part of the user's back, portions 112 at part of the arms, portions 113 arranged between shoulder and neck and portions 114 apt to protect an upper area of the chest; this is illustrated according to different views in
Clearly, the inflatable member 101 can be implemented in several parts distinct therebetween or, in case, a higher number of inflatable members 101 can be provided, to protect different areas of the user body.
When usually worn by the user, the inflatable member 101 is placed into specific containing means 102, which are integral to a garment 104 and it comprises substantially a pocket 128 which extends from the region corresponding to the upper part of the user's back as far as the upper area of the chest, passing above the shoulders. In case that the inflatable members 101 are more than one, several pockets 128 can be provided to house the same.
Said pocket 128 has one or more edges 124 which can be opened and which, during the normal use of the garment 104, are kept closed by means of specific closing means 125, in particular implemented by means of seams 150 with threads having a calibrated breakdown tension. However, such closing means 125 could be implemented also by means of other systems, such as for example snap fasteners or by means of members made of Velcro®.
In the region of the upper part of the back, said pocket 128 defines, at least partially, an aerodynamic appendix 120 shaped like a "hump" usually existing in the suits used by the motorcycling drivers, thereat activation and inflation means (not shown) of said inflatable member and a structure supporting the same can be arranged.
The inflatable member 101 is connected to the containing means 102 by means of reversible connection means 103. In the present case said connection means 103 comprises members 160 made of Velcro® or properly arranged snap fasteners.
During the normal use, for example during a race, the driver is not disturbed in any way by the presence of the inflatable member 101 since it is wholly contained inside the garment 104. In fact, the outer appearance of the garment 104 appears to be substantially equivalent to that of a garment of known art; apart from the use practicality, this is advantageous also from the point of view of the greater visibility of the sponsor logos applied onto the garment.
In case of fall, the activation of the inflation means involves in sequence the increase in volume of the inflatable member 101 inside the pocket 128, the rupture of said seams 150 with calibrated breakdown tension, the opening of the edges 124 and the outcoming of the inflated member 101 from the pocket 128; the member 101, however remaining bound in a correct position to the garment 104 thanks to the connection means 103, fully plays the protection function thereof with respect to the driver.
If the fall has not produced particular consequences, the driver can remove the inflatable member 101 by acting onto the reversible connection means 103 and therefore continue the race without being prevented in the driving by the member 101 itself.
In case, said edges 124 can comprise additional closing means 180, for example made of Velcro®, allowing to close again the pocket 128 once the inflatable member 101 has been removed. This results to be advantageous for the comfort and for the driver's aerodynamic behaviour, apart from the visibility of possible sponsor logos.
