Detailed Description

It is easily understood that according to the technical solution of the present invention, a person skilled in the art can propose various alternative structures and implementation ways without changing the spirit of the present invention. Therefore, the following detailed description and the accompanying drawings are merely illustrative of the technical aspects of the present invention, and should not be construed as all of the present invention or as limitations or limitations on the technical aspects of the present invention.

The terms of orientation of up, down, left, right, front, back, top, bottom, and the like referred to or may be referred to in this specification are defined relative to the configuration shown in the drawings, and are relative terms, and thus may be changed correspondingly according to the position and the use state of the device. Therefore, these and other directional terms should not be construed as limiting terms.

As shown in fig. 1 and 2, the vehicle, such as a general five-seater or seven-seater vehicle, includes: main and auxiliary seats 1,2, rear seats 3 and central armrests 4. An airbag assembly 5 according to an embodiment of the present invention is disposed at a rear end 41 of the center armrest 4. When the airbag body of the airbag assembly 5 is deployed, it includes a first portion 51 and an optional second portion 52, the first portion 51 of the airbag body forming an air cushion that is deployed laterally behind the main and passenger seats 1,2 (backrest). As shown in fig. 6, the first portion 51 of the airbag main body provides cushioning to the occupant 31 in the rear seat to prevent the occupant 31 from directly hitting the main and sub-seats in the event of a vehicle collision. On the other hand, even if the rear-seat passenger 31 is unbelted, the first portion 51 of the airbag main body prevents the passenger 31 from flying forward by inertia from between the main and sub-driver seats to hit the front windshield of the vehicle. On the other hand, the airbag main body may further include a second portion 52, the second portion 52 forming an air cushion longitudinally deployed between the main and sub-driver seats 2,1, the second portion 52 of the airbag main body providing side protection of the main and sub-driver passengers and preventing the main and sub-driver passengers from colliding with each other.

In some embodiments, the balloon body may be T-shaped in cross-section when deployed. In alternative embodiments, the balloon body may also have other suitable shapes in cross-section. In some embodiments, the first and

second portions

51 and 52 of the balloon body may each be of substantially equal thickness flat construction, wherein the thickness of the first portion of the balloon body may be in the range of 150mm to 250mm and the thickness of the second portion of the balloon body may be in the range of 250mm to 350 mm. In some embodiments, to maintain the shape of the airbag body when deployed, one or more internal drawstrings may be included in the first and/or second portions of the airbag body 50. In some embodiments, the inner drawstrings may extend in the thickness direction of the first and second portions of the airbag body, respectively. For example, as shown in FIG. 7, three inner drawstrings 511,512,513 may be provided in the first portion 51 of the airbag body, each extending in the thickness direction of the first portion 51 of the airbag body, and one inner drawstring provided in the second portion 52 of the airbag body, each extending in the thickness direction of the second portion 52 of the airbag body. In alternative embodiments, the number, configuration and location of the internal drawstrings may be modified according to actual requirements, and the internal drawstrings function to control the configuration of the airbag body and direct the air flow to rapidly fill the airbag body.

With continued reference to fig. 3 and 4, the specific structure of the airbag assembly 5 according to the present invention will be described. The airbag assembly may include: a housing 501; a baffle 502 and a gas generator 503 in the housing 501; and an airbag main body 50 connected to the gas generator 502. The gas generator 503 may inflate the airbag body, and the deflector 502 limits the direction of the gas exiting from the gas generator 503. As shown in fig. 3, the airbag main body 50 has a compact mechanism before being deployed so as to be able to be disposed at the rear end 41 of the center armrest.

In another aspect, the present invention also provides a center armrest configured with an airbag assembly according to an embodiment of the present invention. In some embodiments, the rear end 41 of the vehicle center armrest 4 includes a cover plate that covers the airbag body 50, and with continued reference to fig. 5 and 6, the structure of the center armrest 4 is shown with an airbag assembly according to an embodiment of the invention disposed therein, respectively. In this embodiment, the cover plates include a first cover plate 61 connected to the top cover 411 of the center armrest rear end 41 and a second cover plate 62 connected to the rear cover 412 of the center armrest rear end 41. In some embodiments, one side of the first cover plate 61 is pivotally connected (e.g., by a hinge) to the top cover 411 at the rear end of the center armrest, and one side of the second cover plate 62 is pivotally connected (e.g., by a hinge) to the rear cover 412 at the rear end of the center armrest, and the other sides of the first and

second cover plates

61 and 62 are connected to each other by a weakening structure, so that the first and

second cover plates

61 and 62 cover the airbag assembly to conceal it when the airbag is not activated. When the airbag is triggered, the weakened structure between the first cover plate 61 and the second cover plate 62 is broken, and the first cover plate 61 and the second cover plate 62 are pivoted open, respectively, thereby allowing the airbag main body 50 to be deployed in the shape as shown in fig. 5.

The airbag assembly according to the embodiment of the invention can effectively protect front and rear occupants in a vehicle upon a vehicle collision.

The foregoing description of the specific embodiments has been presented only to illustrate the principles of the invention more clearly, and in which various features are shown or described in detail to facilitate an understanding of the principles of the invention. Various modifications or changes to the invention will be readily apparent to those skilled in the art without departing from the scope of the invention. It is to be understood that such modifications and variations are intended to be included within the scope of the present invention.
