Definitions

  • the present invention relates to a deployable airbag pocket and its associated module, preferably intended for users of urban or “soft” mobility vehicles such as, for example, cycles, scooters, skateboards, roller skates, etc.
  • electrically assisted vehicles (bicycles or scooters) often travel at speeds above 20km/h.
  • Cycling helmets that could protect the user from these head injuries are perceived as restrictive and unaesthetic, and contrary to the ideal of simplicity, spontaneity and immediacy offered by urban mobility services such as bicycles or self-service scooters.
  • the patent EP 1 947 966 describes an airbag forming head protection, which deploys when an accident situation is detected. This airbag is integrated into a collar, collar or neck brace, which the user places and locks around their neck.
  • the airbag deploys from the neck brace and surrounds the user's head.
  • the airbag is made of material resistant to tearing and abrasion, and once inflated it absorbs shock and protects the user's head from any object that could damage it and cause potentially serious or even fatal injuries. .
  • this airbag is integrated into a collar which is worn in addition to the user's outfit. If said collar can be integrated into a garment, this garment will be necessarily closed on the upper body of the user. This garment will therefore be of the jacket, vest or sweater type.
  • the legs of the stiffening structures of this airbag pocket form a power take-off for deployment in position around the user's head. These legs are easily integrated into the straps of a backpack, or into a vest or garment that can be cut out and does not have to be closed around the neck.
  • the upper loops further stiffen the portion surrounding the user's head.
  • the airbag pocket according to the invention may also have one or more of the following characteristics.
  • the upper loops of the stiffening structures can be made in an annular form, with a thinner central portion, preferably planar.
  • the central portion can be inflated at least partially during deployment in the middle, the central portion preferably having a constriction and a baffle to limit the circulation of gas for the duration of an impact.
  • the legs of the stiffening structures located in the deployed state on the front of the user's torso are advantageously curved with a concave forward curvature.
  • the legs of the stiffening structures located in the deployed state on the front of the user's torso may include transverse flanges which, once inflated, form at least one protective pectoral plate.
  • This pectoral plate protects the user's chest and will absorb a shock, for example against the ground.
  • the legs of the stiffening structures located in the deployed state at the rear of the user may include transverse flanges which, once inflated, form at least one protective dorsal plate.
  • This back plate protects the user's back and will absorb a shock, for example against the ground.
  • transverse tubes can also be connected to the corresponding leg of the stiffening structure by a constriction making it possible to limit the circulation of gas towards the leg of the stiffening structure during the duration of an impact, and include two cords, the ends of which are attached to a high point and a low point of one of the front legs of the stiffening structures, and passing through a sliding connection located in the middle of the free end of the pectoral plate connected to the front leg, which folds, in the state inflated, the pectoral plate against the user's torso.
  • the vault may include baffles, stiffening the vault in the deployed state, forming preferential folding lines and limiting the circulation of gas in the event of impact on this vault.
  • the airbag pocket advantageously comprises two gas inlet pipes each opening into one of the legs of the stiffening structures located, in the deployed state, in the back of the user, at the level of the upper third of said leg of the stiffening structures.
  • the invention also relates to the backpack, characterized in that it comprises said airbag, in which the front legs of the stiffening structures are located, in the folded state, in housings arranged in the straps of the bag -back-to-back, the housings being closed by disengageable mechanical links, which open under the action of the inflation of the airbag pocket.
  • These disengageable mechanical links may in particular comprise at least one of: a disengageable zipper, a fusible seam, press studs, self-gripping strips with textile loops and hooks.
  • the backpack may comprise a bag body comprising a bag body close to the user's back incorporating the mentioned airbag, and a separate removable part forming a storage space.
  • FIG. 1 is a schematic representation of a user U falling from an urban mobility device 100, here a scooter.
  • urban mobility devices can be bicycles, skateboards, self-balancing scooters and their variants, particularly with electric assistance or motorization.
  • the user U is in the process of falling, for example following a collision of the urban mobility machine 100 with an obstacle, here a step or a sidewalk.
  • the user U is equipped with an airbag 1, the pocket 3 of which is deployed.
  • the pocket 3 of the airbag 1 surrounds in particular the head of the user U, shown in dotted lines.
  • the pocket 3 is notably contained, in the folded and deflated state, in a backpack 5.
  • the bust of user U is represented front to back figure 2 with the airbag 1 whose pocket 3 is folded, and in Figure 3 with a deployed pocket.
  • the pocket 3 comprises a closed body, made of flexible and resistant material, in particular to tears and high temperatures, of the type used for usual airbags, for example automobiles.
  • the material of the pocket 3 is for example a polyamide 6.6 or polyester textile, braided and coated with silicone or laminated with a waterproof film.
  • the airbag is advantageously made in one piece weave (“One Piece Woven” in English), that is to say woven as a whole in a single piece. This greatly increases its gas tightness.
  • the body of pocket 3 is composed of several distinct volumes, separated by constrictions or elbows.
  • the body of the pocket 3 comprises in particular two stiffening structures 31, located laterally on either side of the user's head U and in the shape of an R.
  • the shape of the stiffening structure 31 in R is apparent in figure 1 , where the deployed pocket 3 is observed from the side.
  • Their arrangement on each side of the head of the user U is apparent in Figure 3 , which is a front view.
  • stiffening structures 31 each comprise two tubes forming the legs of the R, arranged one in front, the other behind the shoulder of the user U.
  • a tube ring forms the top loop of the R, located on one side of the user U's head.
  • the stiffening structures 31 can have comparable shapes: in A, in X or in K, always with two lower legs and an upper part located on the side of the user's head U.
  • the body of the pocket 3 further comprises a vault 33 connecting the tops of the upper loops of the stiffening structures 31, and covering in the deployed state at least the nape of the neck and the top of the skull of the user U.
  • the vault 33 and the upper loops of the stiffening structures 31, in the inflated state form a protection surrounding the user's head U
  • the legs of the stiffening structures 31 form a power take-off against the bust and the back of the user U. Their power take-off against the bust and the back then ensures the correct deployment of the pocket 3, in particular without the arch 33 not hangs at the neck of the user U.
  • the legs of the stiffening structures 31 located in the deployed state on the front of the bust of the user U are advantageously curved with a concave curvature towards the front.
  • the upper loops of the stiffening structures 31 are made in annular form, with a central portion 35 which is preferably flat in the inflated state. This recessed central portion 35 allows power to be taken from the side of the user U's head.
  • the legs of the stiffening structures 31 which are located on the front of the user U's bust extend into plates 37, transverse in the deployed state, forming a protective pectoral.
  • FIG. 31 may have additional flaps to protect other parts of the body of the user U: in the back, starting from the rear legs of the stiffening structure 31 and forming a back, shoulder pads, hip protectors etc. Said flaps are connected to the stiffening structures 31, and extend from them during inflation.
  • FIG. 2 And 4 show in more detail the backpack 5 and how the airbag 3 is integrated into it.
  • FIG. 4 shows user U wearing backpack 5 in profile.
  • the backpack 5 further comprises a bag body 53, which the user U carries on his back.
  • the straps 51 are connected to the bag body 53 and hold it against the back of the user U when he is worn.
  • the bag body 53 contains in particular a part of the pocket 3, and the actuation mechanism of the airbag 1: a trigger 7 which detects an accident situation, and one or more cartridges 9, to which the trigger 7 is connected .
  • the trigger 7 When the trigger 7 detects an accident situation, it triggers the cartridge(s) 9, which inflates the pocket 3.
  • the trigger 7 is for example provided with inertial sensors, with a control unit configured to discriminate in real time, among the signals coming from the inertial sensors, acceleration markers specific to accident situations in which the pocket 3 must be deployed .
  • the backpack 5 includes a chest strap 55, closed by a buckle 56.
  • the chest strap 55 includes in particular a switch actuated by the closing of the buckle 56. Actuation of this switch activates the trigger 7, for example by closing a power supply circuit for the inertial sensors.
  • the cartridges 9 are for example pyrotechnic cartridges, in which an explosive reaction generates the gas which will inflate the bag 3.
  • the cartridges 9 can be bottles of compressed gas, with a punch controlled by the trigger 7.
  • FIG. 5 shows the components of the airbag 1 outside the backpack 5.
  • the pocket 3 of the airbag 1 is further represented by its flat pattern.
  • the lateral edges of the portion forming the arch 33 are sewn and/or glued and/or welded to the upper curved edge of the upper loops of the stiffening structures 31 (dotted arrows in Figure 5 ).
  • the pocket 3 of the airbag 1 comprises two gas inlet pipes 39 each opening into one of the legs of the stiffening structures 31 located, in the deployed state, at the level of the back of the user U, at the level of the upper third of said leg.
  • the plates 37 forming pectoral protection comprise transverse flanges 37a, 37b, 37c which are connected to the front leg of the stiffening structure 31 each by a constriction allowing both to limit the circulation of gas towards the front leg of the R for the duration of an impact on the pectoral part but also to facilitate the formation of the elbow of said transverse flanges 37a, 37b, 37c relative to the leg of the stiffening structure 31.
  • a cord 36 structures and holds in position each of the plates 37 forming pectoral protection.
  • the cords 36 have their ends attached to the front leg of the stiffening structures 31, at a high point and a low point of said leg for each of the ends of each cord 36.
  • the cords 36 pass through a sliding connection 38, located in the middle of the free end of the plate 37 associated with them.
  • the cords 36 can in particular slide in the sliding connection 38, which is for example produced by means of a sewn loop through which the cord 36 passes.
  • the cord 36 is of such length that, when the pocket 3 is inflated, it pulls on the free end of the plate 37 via the sliding connection 38. By pulling on the free end of the plate 37, the cord 36 folds said plate against the user U's torso.
  • the cords 36 can in particular be elastic, and stretched under the effect of inflation.
  • the vault 33 has baffles, formed by making transverse strips sewn, welded or glued, on the path of the gas entering the volume of the vault 33, alternated with constrictions.
  • baffles stiffen the vault in the deployed state, while forming privileged places for the emergence of folds curving the vault 33 to enable it to follow the curvature of the loops of the stiffening structures 31.
  • the baffles limit the circulation of gas towards the dorsal part of the airbag during an impact on the part above or behind the head. We can then associate good impact performance and a low inflated thickness for this part of the pocket 3.
  • a part of the pocket 3, in particular the legs of the stiffening structures 31 are located, in the folded state, in housings 57 arranged in the straps 51 of the backpack 5.
  • These housings 57 are closed by mechanical links 59 detachable, such as a detachable zipper, fusible seam, snap buttons, hook-and-loop straps with textile hooks and loops.
  • These mechanical links 59 are opened under the action of the inflation of the pocket 3 of the airbag 1.
  • the part of the pocket 3 forming, in the inflated state, the arch 33 and the upper loops of the stiffening structures 31 is contained in a dorsal housing 58 of the backpack 5, close to the neck and the head of the user U
  • This dorsal housing 58 is also closed by disengageable mechanical links (not shown).
  • the disengageable mechanical links 59 let go.
  • the housings 57 of the straps 51 as well as the back housing 58 of the bag body 53 open, which releases the pocket 3 which can then be deployed.
  • the stiffening structures 31 deploy and inflate the most quickly, because they are connected first to the cartridges 9, with a large and almost uniform section over their entire volume, without obstacle to air circulation.
  • the upper loops of the stiffening structures 31 are folded into the dorsal housing 58 of the backpack 5 with the arch 33, and will take a little longer to inflate completely, in particular with sufficient pressure to stiffen them.
  • the back housing 58, the trigger 7 and the cartridges 9 are contained in the bag body 53 close to the back of the user U.
  • the bag 5 further comprises a separate removable portion 54, for example by means of a zipper, which forms a storage space for the user's belongings, and which is fixed interchangeably against the rest of the backpack 5, comprising the bag body 53 containing the airbag 1 and the straps 51.
  • a separate removable portion 54 for example by means of a zipper, which forms a storage space for the user's belongings, and which is fixed interchangeably against the rest of the backpack 5, comprising the bag body 53 containing the airbag 1 and the straps 51.
  • stiffening structures 31 in particular of their front and rear legs, allows them to stiffen first, and then to form a base and a power take-off for the correct deployment of the rest of the pocket 3.
  • the upper loops of the stiffening structures 31 form a guide during the deployment of the arch 33, with which they are in power take-off, which ensures that the arch 33 does not come into contact with the neck or the back of the head of user U.
  • the central portion 35 in the middle of the loops of the stiffening structures 31 is flat, without inflation.
  • FIG. 6 shows an alternative embodiment of the pocket 3, represented by its planar pattern in a manner analogous to the Figure 5 .
  • Pocket 3 of the Figure 6 differs from that of the Figure 5 in that the central portions 35 of the loops of the stiffening structures 31 are here produced in the form of pockets which inflate during deployment of the airbag 1.
  • the central portions 35 here include a constriction followed by baffles, to limit the circulation of gas towards the outside of this central portion 35 during an impact.
  • the central portions 35 are of less thickness compared to the loop, to form a housing for the temple and the ear of the user U.
  • Lines A, B, C, D, E and F illustrate in Figure 7 folding the deflated pocket 3 to put it back in the backpack 5, for example following deployment.
  • the first line A is located at the end of the portion of the pocket 3 forming the vault 33, and runs along the extremal edge of this portion.
  • Line B is located at the end of the chicanes limiting the air entry into vault 33, and is parallel to line A.
  • Line C is located at the base of said portion of the pocket 3 forming the arch 33, at the level of the lower edge of the segment of the pocket 3 connecting the two rear legs of the stiffening structures 31.
  • the fourth line D is located at the free end of the pectoral plates 37.
  • the fifth line E is located at the level of the constrictions of the flanges 37a, 37b, 37c at the base of the pectoral plates 37, and is parallel to the fourth line D.
  • the sixth line F is at the level of the edge opposite the pectoral plates 37 of the front leg of the stiffening structure 31, parallel to the fourth and fifth lines D, E.
  • the folding of the pocket 3 is then advantageously carried out as follows.
  • the portion of pocket 3 between lines A and B is rolled up on itself.
  • the portion of pocket 3 between lines B and C is then folded in an accordion or zigzag, which is represented by dotted folding lines, parallel and regularly distributed between lines B and C.
  • This portion of the pocket corresponding to the arch 33 and the upper loops of the stiffening structures is then inserted into the dorsal housing 58 of the backpack 5.
  • FIG. 7 shows an alternative embodiment, in which the airbag 1 is integrated into a vest 11 instead of the backpack 5.
  • the housings 57 closed by the mechanical fuses 59 are here located at the level of the shoulders of the user U, not not in straps 51, but directly in the vest 11, with a similar arrangement compared to the embodiment comprising a backpack 5.
  • the trigger 7 and the cartridges 9 are for example arranged in a backbone (not shown), as well as the back housing 58 containing the portion of the pocket 3 corresponding to the loops and the arch 33.
  • the pocket 3 of airbag 1 according to the invention is therefore easily integrated into a backpack 5 of usual shape. It takes advantage of the presence of straps 51, in which the portion of the pocket 3 corresponding to the front legs and the pectoral plates 37 is inserted into the housings 57.
  • the pocket 3 according to the invention has continuous and improved deployment kinematics compared to the state of the art.
  • the stiffening structures 31 are the first to inflate with a sufficient section to become semi-rigid.
