Abstract

The disclosure discloses a passenger airbag apparatus comprising: an airbag configured to inflates and expands from an opening; a retainer configured to comprise a body having substantially rectangular frame-shaped side walls; arm members configured to extend respectively from the side walls along a left and right directions, and to be affixed to the panel; a substantially disk-shaped gas generator attached to the bottom surface of the body; and a support member arranged in a manner that the upper end portion thereof is attached to an outer periphery of the opening and to cover the sides of the airbag, wherein: the retainer further includes hook members provided on the side walls along a front and rear directions, and engage the body with the support member; the body and the hook members are integrally constructed with substantially the same thickness; and the hook members further includes a first rib portion.

Claims

1. A passenger airbag apparatus comprising:

an airbag configured to inflates and expands between a panel and a passenger from an opening provided in said panel, the panel constituting an inner wall of a vehicle;

a retainer configured to comprise a body having a substantially rectangular bottom surface and substantially rectangular frame-shaped side walls and to house said airbag in a folded state;

arm members configured to extend respectively from said side walls along a left and right directions of said vehicle in a state where said retainer is attached to said vehicle, and to be affixed to said panel;

a substantially disk-shaped gas generator attached to said bottom surface of said body and configured to supply gas to said airbag; and

a support member arranged in a manner that the upper end portion thereof is attached to an outer periphery of said opening of said panel and to cover the sides of said airbag in the folded state, wherein;

said retainer further includes hook members provided on said side walls along a front and rear directions of said vehicle in the state where said retainer is attached to said vehicle, and engage said body with said support member by passing through through-holes provided in said support member;

said body and said hook members are integrally constructed with substantially the same thickness by extrusion molding; and

said hook members further includes a first rib portion.

2. The passenger airbag apparatus according to claim 1, wherein:

said body further includes a flange having a shape that widens toward an edge side, on an upper end portion of an entire periphery of said substantially rectangular frame-shaped side walls.

3. The passenger airbag apparatus according to claim 1, wherein:

said first rib portion of said hook members extends along a direction of protrusion of the hook member; and

said body further includes second rib portions formed so as to be continuous respectively with said first rib portions of said hook members.

4. The passenger airbag apparatus according to claim 1, wherein:

said body has the same height dimension along the entire periphery of said substantially rectangular frame-shaped side walls.
