Embodiment Construction

[0029] Referring to the accompanying drawings, the steering wheel airbag device provided in the figure, the whole airbag device 100 is installed in the steering wheel 200, which includes a cover plate 110, an air bag bracket 120 and an air bag (not shown in the figure) configured in the air bag bracket 120 ) and an inflatable component (not shown) installed on the airbag bracket 120, the airbag bracket 120 is fixed on the steering wheel 200.

[0030] The cover plate 110 includes a cover plate panel 111 and a cover plate wall 112 , the lower end of the cover plate wall 112 is fixedly connected with the airbag bracket 120 by clamping or riveting.

[0031] After the cover plate 110 is installed on the airbag support 120, after the cover plate panel 111 is subjected to a downward pressing force and the horn is sounded, the bottom surface of the cover plate panel 111 contacts the top edge of the airbag support 120, and the cover plate panel 111 The pressing force received is transm...

Abstract

The invention discloses a cover plate of a safety airbag. The cover plate comprises a cover plate panel and a cover plate wall body which is connected to the side edge of the bottom surface of the cover plate panel, wherein a tear structure is arranged between the bottom surface of the cover plate panel and the cover plate wall body. The invention further discloses a steering wheel safety airbag device comprising the cover plate. According to the cover plate of the safety airbag, a tear line of the safety airbag cover plate is arranged on a joint part of the cover plate panel and the cover plate wall body. When a horn cover plate is pressed, pressing force is safely transmitted to the safety airbag bracket, the tear structure between the cover plate panel and the cover plate wall body does not bear pressure, does not have a fracture risk and can be designed to be relatively thin, so that a purpose of easily opening is achieved; moreover, the appearance quality is improved, and the manufacturing cost is reduced.

Description

technical field [0001] The invention relates to the technical field of vehicle safety airbags, in particular to a cover plate of an easy-to-open safety airbag and a steering wheel safety airbag device comprising the cover plate. Background technique [0002] Existing automotive airbag covers are mostly made of engineering plastics. On the cover facing passengers, the partial thickness is thinned to form a tear structure with lower strength than other positions. When the airbag is deployed, an opening is formed at the position of the tear line on the cover plate facing the passenger, so that the airbag rushes out from the formed opening. Although the tearing structure is designed to be relatively weak, since the airbag cover also functions as a horn press, when the airbag cover is pressed, the tearing structure will be subjected to stretching and shearing forces and is easy to tear. In order to keep pressing for a long time without cracking from the tear structure, the tear ...
