Non-hinge type auxiliary airbag support

Abstract

The invention provides a non-hinge type auxiliary airbag support and relates to an automobile airbag support. The non-hinge type auxiliary airbag support comprises a support frame, a turnover plate Iand a turnover plate II, wherein the outer side of the support frame, the outer side of the turnover plate I and the outer side of the turnover plate II are connected with an IP body, and the tear line of the IP body is located between the turnover plate I and the turnover plate II; the support frame is connected with the turnover plate I and the turnover plate II through positioning grooves respectively, and in the positioning grooves, the distances between the support frame and the turnover plates are larger than or equal to the maximum travel distance of the turnover plates needing to moveupwards in the overturning process; hanging hook holes A are formed in the support frame, hanging hook holes B with the lengths larger than those of the hanging hook holes A are formed in the turnoverplates respectively, an auxiliary airbag is hooked into the hanging hook holes A and the hanging hook holes B through hanging hooks, and the distance between the lower edge of each hanging hook holeB and the corresponding hanging hook is larger than or equal to the maximum travel distance of the turnover plates needing to move upwards in the overturning process. By means of the non-hinge type auxiliary airbag support, the phenomenon that the distance between the auxiliary airbag and the IP body is too small, so that the auxiliary airbag is exploded to lose efficacy can be avoided, and the non-hinge type auxiliary airbag support has the advantages of being good in reliability, simple in structure and low in cost, and is easy to apply and popularize.

Description

technical field [0001] The invention relates to an automobile airbag bracket, in particular to a non-hinge auxiliary airbag bracket. Background technique [0002] At present, with the development of automobile technology and the improvement of consumers' attention to automobile driving safety, passenger airbags (that is, co-pilot airbags, referred to as PAB or auxiliary airbags) have become an indispensable configuration of automobiles. Generally, the PAB is hung on the plastic bracket 6 and welded together by vibration friction welding between the plastic bracket 6 and the IP body 3 (see Figure 4 ). There is a U-shaped hinge structure extending downwards on the plastic bracket 6 . When the auxiliary airbag 4 explodes, under the impact force, the flipped part of the plastic bracket 6 will flip during the stretching process of the U-shaped hinge 601 . The IP body 3 is linearly weakened around the flipped part of the plastic bracket 6, and the weakened area of ​​the IP body ...

AI Technical Summary

Problems solved by technology

In some cases, there is indeed a problem that the distance between the auxiliary airbag and the plastic bracket is too small, which will cause the explosion failure of the auxiliary airbag
