Abstract

The object of the present invention is to provide an air bag device of the type in which a door frame movable body and a door frame fixed body are provided on the inner surface of an interior trim panel, and the door portion is opened while the door frame movable body moves upward, and the air bag device used The cover, which can be easily manufactured and has improved dimensional accuracy. When the inflator (14) performs the gas ejection operation, the door frame movable body (32) moves upward (rising operation). The module cover (20) is broken along the tear line (22b), and the door portion (24) is disconnected from the surrounding module cover (20). The door portion (24) continues to move upward together with the door frame movable body (32), and under the extrusion of the air bag (12), the tear line (22a) of the door portion (24) breaks, and the door portion (24) and Each liner portion (32a, 32a) is opened like a door in two in the vehicle front-rear direction, and the airbag (12) is inflated indoors.

Description

technical field [0001] The present invention relates to an airbag device installed in a passenger seat of an automobile, and more particularly, to an airbag device of a type in which a door is raised toward the interior of a room and opened when the airbag is inflated. Furthermore, the present invention also relates to a cover used for the airbag device. Background technique [0002] An airbag device for a passenger's seat installed in an automobile includes a folded airbag, a holder for mounting the airbag, an inflator (gas generator) for inflating the airbag, and a module cover arranged in front of the holder Or component door department, etc. [0003] When the inflator generates gas, the airbag starts to inflate, the module cover or the door of the module cover is cracked and opened along the tear line, and the airbag deploys toward the vehicle interior to protect the occupants. [0004] Japanese Unexamined Patent Publication No. 2003-137054 discloses an airbag device t...
