Abstract

An airbag-device cover is provided which has a door portion that is torn from an interior panel along a tear line in response to inflation of an airbag so as to be deployed outward towards the inside of a vehicle cabin, and which also has a reinforcement frame and a backing member respectively attached to a peripheral area and a back face of the door portion by vibration welding, such that the frame and the backing member extend to areas of the interior panel that are adjacent to the tear line, and moreover, to provide an airbag device equipped with such an airbag-device cover. An instrument panel body 7 is provided with a door portion 13 which is surrounded by a tear line 11. Of the welding ribs 31, trunk ribs 31A, 31B that are disposed closest to the tear line 11 respectively have branch ribs 32a, 32b protruding therefrom towards the tear line 11. The branch ribs 32a, 32b are narrower in width than the trunk ribs 31A, 31B.

Description

technical field [0001] The present invention relates to a cover for an airbag device having a door portion that is torn from an interior panel along a tear line when the airbag is inflated and opens toward the interior of a vehicle interior, and more particularly relates to a cover for an airbag device that is opened by Vibration welding is used to weld the frame and lining members for reinforcement around and inside the door. In addition, the present invention relates to an airbag device having the airbag device cover. Background technique [0002] Japanese Unexamined Patent Application Publication No. 2005-153545 discloses an example of a cover for an airbag device that has a door portion that is torn from the interior panel along a tear line when the airbag is inflated and opened toward the interior of the vehicle interior, and around the door portion , The frame and inner lining parts for reinforcement are welded by vibration welding on the inner side. [0003] Figure...
