Embodiment Construction

[0030] Such as image 3 , Figure 4 As shown, the frame-shaped safety airbag airbag installed on the roof of the car, the airbag 1 is in a frame-shaped structure when inflated and expanded, and is protected by the interconnected airbag upper frame air inlet channel 1A and the airbag left frame. Area 1B, air bag right frame protection area 1C and air bag lower frame protection area 1D constitute.

[0031] The air bag upper frame air inlet 1A top surface is the installation surface with the car roof 6 and is provided with an air bag air inlet 1E. The middle part of the upper surface of the lower frame protection area 1D of the air bag is provided with an upward raised portion 1G, and the planes 1H on both sides of the upward raised portion 1G are respectively connected to the left frame protection area 1B of the air bag and the right frame protection area 1C of the air bag. connected. The cross-section of the upward raised portion 1G is dovetail-shaped and arranged along the ...

Abstract

The invention relates to a frame-structured supplementary restraint system air bag mounted on a roof of an automobile. The frame-structured supplementary restraint system air bag mounted on the roof of the automobile is characterized in that the air bag which is inflated and unfolded has a frame structure, the air bag consists of an air bag upper frame air inlet channel, an air bag left frame protecting region, an air bag right frame protecting region and an air bag lower frame protecting region which communicate with one another, wherein the top surface of the air bag upper frame air inlet channel is a mounting surface of the roof of the automobile; an air bag air inlet is formed in the top surface of the air bag upper frame air inlet channel; an upward projection is arranged in the middle of the upper surface of the air bag lower frame protecting region; planes of two sides of the upward projection are respectively connected with the air bag left frame protecting region and the air bag right frame protecting region; an exhaust hole is formed in the top surface of the upward projection; and inward pulling straps which are connected to inner walls of two sides are respectively arranged in the air bag left frame protecting region and the air bag right frame protecting region. The frame-structured supplementary restraint system air bag is simple in structural design and convenient to make; shortcomings in the prior art are overcome; meanwhile, requirements of a novel supplementary restraint system on front-side protection of front drivers and passengers or rear passengers are met; and the protection standard of the international laws to drivers and passengers of automobiles is met.

Description

technical field [0001] The invention relates to an automobile safety airbag airbag structure, in particular to a frame-shaped safety airbag airbag installed on the roof of an automobile. Background technique [0002] In order to reduce the injuries of the driver and passengers when the car is in a frontal collision, and reduce the replacement and maintenance cost of the car airbag, the design of the car airbag installed on the roof of the car has appeared. [0003] At present, the airbags of the roof airbags of automobiles include curtain-shaped airbags, L-shaped airbags and chair-shaped airbags. In the research and development process of the car roof airbag, according to the new airbag protection index requirements, the protective effects of the above airbags with different shapes on the dummy were tested, but none of them fully reached the neck injury index My value of the airbag on the dummy. protection requirements. Therefore, integrating the test data extracted during...
