Problems solved by technology

Since the thickness of the material at the position of the tear line is thinner than that of the surrounding material, and the width of the tear line is relatively narrow, it is easy to produce injection sink marks on the surface of the decorative cover during the injection molding process, which affects the surface appearance quality of the decorative cover.
At the same time, after the tear line is torn, the sharp edges around it will contact and rub against the air bag rushing out at high speed, which will easily cut the bag body of the air bag and reduce the protective performance of the air bag.

Abstract

An SRS (Supplementary Restraint System) cover turning device mounted on a steering wheel comprises a decorative cover and an airbag housing, and is characterized in that the decorative cover and the airbag housing are buckled with each other, the decorative cover adopts a cover turning structure, the decorative cover and the airbag housing are connected with each other through a flexible connecting band, and the airbag is turned from the rear part of the decorative cover after initiation. The cover turnover structure changes the traditional mode of unfolding the airbag, no tear lines are designed on the decorative cover, the decorative cover adopts the cover turning structure, the decorative cover and the airbag housing are connected with each other through the flexible connecting band, buckling structures are arranged on the periphery of the decorative cover and the airbag housing, so that the airbag is easy to unfold, the surface quality of the A surface of the decorative cover is improved, and the protection performance is improved.

Description

technical field [0001] The invention relates to an overturning device for a decorative cover of an airbag installed on the steering wheel of an automobile. Background technique [0002] Existing airbag trim covers are provided with weakening lines or tear line structures. When the airbag is deployed, the trim cover is fixed, and an opening is torn at the position of the tear line on the trim cover, and the airbag passes through the torn opening. rushed out. Since the thickness of the material at the position of the tear line is thinner than that of the surrounding material, and the width of the tear line is relatively narrow, it is easy to produce injection sink marks on the surface of the decorative cover during the injection molding process, which affects the surface appearance quality of the decorative cover. Simultaneously, after the tearing line is torn, the sharp edges around it contact and rub against the airbag rushing out at high speed, which will easily cut the ba...
