Description

Technical Field

[0001] This utility model relates to the field of automotive airbag technology, and in particular to an improved remote airbag. Background Technology

[0002] A far-side airbag (FSAB) is a safety airbag installed on the inside of the driver's seat back or between the driver and front passenger seats. It is mainly used to protect occupants from injury caused by lateral movement or collisions with other objects inside the vehicle (such as passengers on the other side, doors, or the center console) during side collisions or vehicle rollovers.

[0003] Existing remote airbags are generally similar to SABs (front seat airbags), using PET wrapping fabric. This wrapping method is not ideal for shaping the folded remote airbag, leaving it loose for extended periods. Although there is space reserved within the seat for the installation of the remote airbag and foam, the large size of the remote airbag itself, its thickness when folded, and the special styling required by existing seats further complicate the space constraints. Furthermore, many vehicle models still use seat frames from previous models without remote airbags, which, when combined with a large remote airbag, also contributes to insufficient seat space.

[0004] Therefore, through beneficial exploration and research, the applicant has found a solution to the above problems, and the technical solution to be introduced below is the result of this research. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide an improved distal airbag that can be used to cover and shape airbags when seat space is tight, in order to overcome the shortcomings of the existing technology.

[0006] The technical problem to be solved by this utility model can be achieved by the following technical solution:

[0007] An improved distal airbag includes:

[0008] An airbag mounting box that is fixedly mounted on the seat frame and located on the inner side of the seat surface;

[0009] The distal airbag is installed in a folded manner inside the airbag mounting box.

[0010] A gas generator disposed within the airbag mounting housing for inflating the distal airbag inflator upon detonation; and

[0011] A rigid cover is disposed on the airbag mounting box and located on the inside of the seat surface, and the portion of the rigid cover facing the seat surface is provided with a tear line;

[0012] When the gas generator is ignited, it produces a large amount of gas that fills the distal airbag, causing the distal airbag to expand and expand outward after breaking through the tear line of the rigid cover.

[0013] In a preferred embodiment of the present invention, the rigid cover includes an upper cover and a lower cover. The lower cover is fixed inside the seat and surrounds the outer periphery of the airbag mounting box. Left and right side slots are formed on the bottom surface of the inner periphery of the lower cover. The upper cover is disposed on the airbag mounting box, and left and right side buckles that cooperate with the left and right side slots are formed at its lower periphery. The tear line is disposed inside the top of the upper cover.

[0014] In a preferred embodiment of this utility model, the left and right side buckles are triangular buckles.

[0015] In a preferred embodiment of the present invention, the thickness of the support surface of the lower cover on the side closer to the gas generator is greater than the thickness of the support surface on the side farther away from the gas generator.

[0016] In a preferred embodiment of this utility model, the distance between the top surface of the upper cover and the inner surface of the seat surface is 3.5mm to 4mm.

[0017] In a preferred embodiment of the present invention, the tear line is arranged along the periphery of the top of the upper cover.

[0018] In a preferred embodiment of this invention, the tear line adopts a V-groove design.

[0019] Due to the adoption of the above technical solution, the beneficial effects of this utility model are as follows:

[0020] 1. This utility model uses a rigid shell to cover the distal airbag and shape the folded distal airbag, so that the folded distal airbag maintains a certain thickness and avoids the folded distal airbag being in a loose state for a long time.

[0021] 2. This utility model eliminates the foaming structure between the remote airbag and the seat surface, increasing the Y-axis spatial distance by 13.5mm to 15mm, improving the installation space of the remote airbag, and reducing the ejection of foam during airbag deployment.

[0022] 3. This utility model adopts a structural design with separate upper and lower covers and snap-fit ​​connections, which significantly improves the assembly and strength of the cover. Attached Figure Description

[0029] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0030] See Figure 1 The figure shows a modified distal airbag, including an airbag mounting box 100, a distal airbag bag 200, a gas generator 300, and a rigid cover 400.

[0031] The airbag mounting housing 100 is fixedly mounted on the seat frame 10 and located inside the seat surface 20. In this embodiment, the airbag mounting housing 100 is made of rigid plastic. The distal airbag bladder 200 is folded and mounted inside the airbag mounting housing 100. A gas generator 300 is disposed inside the airbag mounting housing 100 and is used to inflate the distal airbag bladder 200 upon deployment. A rigid cover 400 is placed on the airbag mounting housing 100 and located inside the seat surface 20. The portion of the rigid cover 400 facing the seat surface 20 has a tear line 411. In this embodiment, the rigid cover 400 is made of rigid plastic.

[0032] When the gas generator 300 is detonated, it generates a large amount of gas that fills the distal airbag 200, causing the distal airbag 200 to expand and break through the tear line 411 of the rigid cover 400 before unfolding outward.

[0033] This invention employs a rigid shell, such as an airbag mounting box 100 and a rigid cover 400, to enclose the distal airbag 200, shaping the folded distal airbag 200 to maintain a certain thickness and prevent it from remaining loose for extended periods. Simultaneously, this invention eliminates the foam structure between the distal airbag and the seat surface 20, increasing the Y-axis spatial distance by 13.5mm–15mm, thus improving the installation space for the distal airbag and reducing the ejection of foam material during airbag deployment.

[0034] See Figures 2 to 4 The rigid cover 400 includes an upper cover 410 and a lower cover 420. The lower cover 420 is fixed inside the seat and surrounds the outer periphery of the airbag mounting box 100. Left and right side slots 421 and 422 are formed on the bottom surface of the inner periphery of the lower cover 420. The upper cover 410 is disposed on the airbag mounting box 100, and the distance between its top surface and the inner surface of the seat surface 20 is 3.5mm to 4mm. Left and right side buckles 412 and 413 are formed at its lower periphery to cooperate with the left and right side slots 421 and 422. In this embodiment, the left and right side buckles 412 and 413 are triangular buckles with a holding angle of 50° to 70°, a width of 20mm to 27.5mm, a thickness of 3mm to 5mm, a length of 3mm to 5mm, and a depth of 2mm to 2.7mm.

[0035] The thickness of the support surface of the lower cover 420 on the side closer to the gas generator 300 is greater than the thickness of the support surface on the side farther from the gas generator. In this embodiment, the thickness of the left support surface of the lower cover 420 is set to 3.5mm to 4.0mm, and the thickness of the right support surface is set to 1.5mm to 2mm. This is mainly because the matching relationship between the buckle and the slot is such that a higher degree of locking and a stronger snap-fit ​​makes installation more difficult. The left side of the lower cover 420 is the gas outlet side of the generator and is subject to greater impact force. Therefore, the left side of the lower cover 420 is locally reinforced, while the right side is subject to less impact force and is locally weakened, thus reducing the installation pressure.

[0036] A tear line 411 is disposed inside the top of the upper cover 410, and is arranged along the periphery of the top of the upper cover 410. In this embodiment, the tear line 411 adopts a V-groove design, such as... Figure 5 As shown, while maintaining a certain level of strength, it can also ensure that the airbags deploy smoothly.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
