Abstract

Disclosed is an airbag door structure for vehicular passenger seats having an airbag door and a crash pad integrally formed, preferably in a dual injection molding process using different materials to hide tear lines of the airbag door and crash pad for aesthetic appearance. The airbag door structure can have a reduced number of components to decrease weight and save cost and uses a material undergoing sever change in physical properties as temperature varies for the crash pad and a ductile material undergoing little change as temperature varies for the airbag door so that the airbag can expand stably at various external temperatures without being easily tom off by impact from outside the door.

Description

technical field [0001] The present invention relates to an airbag door structure for a passenger seat of an automobile, and more particularly relates to integrally forming an airbag door and a crash pad in a double injection molding process using different materials to reduce cost and weight , and provide an airbag door structure for an automobile passenger seat with very good expansion performance, strong external impact resistance and improved quality. Background technique [0002] Generally, airbags are placed in front of the driver and passenger seats to protect occupants in the event of an accident. [0003] Passenger airbags are typically placed on top of the car's glove box under the dashboard. [0004] A typical passenger airbag is usually a seamless airbag and it works like this: when the airbag starts to inflate, pressure is applied to the door panel and the tear line around the door cover is torn by laser scoring drop, allowing the airbag to inflate. [0005] T...
