Abstract

An air bag door for a passenger seat of an automobile for improving a coupling construction of an air bag door and a housing. The air bag module for the passenger seat according to the present invention comprises inflators; a lower housing for receiving the inflators; an upper housing coupled to a top portion of the lower housing, for receiving an air cushion to be positioned upper the inflators; a pair of door retainers coupled with predetermined intervals to the inner sides of both longitude-directional lateral-walls of the upper housing; and an air bag door which covers an upper portion of the air cushion and is coupled with the upper housing, wherein in the both lateral-wall parts of the upper housing, a plurality of concavities are formed and arranged in a manner to be caved in by predetermined distances on each of the lateral-wall sides, and a plurality of coupling holes, which are coupled elastically with the concavities, are formed in both lateral-wall parts of the air bag door corresponding to the both lateral-wall parts of the upper housing. In accordance with the present invention, it is possible to significantly reduce weight and production cost of the air bag module, as well as easily couples an air bag door with a housing without separate external fixtures.

Claims

1. An air bag module for a passenger seat of an automobile, comprising:

a lower housing for receiving inflators;

an upper housing coupled to a top portion of the lower housing, for receiving an air cushion to be positioned an upper portion of the inflators; and

an air bag door for covering an upper portion of the air cushion and coupled with the upper housing,

wherein a plurality of concavities are arranged and formed in a manner to be caved in by predetermined distances on each of the lateral-wall sides in the both lateral-wall parts of the upper housing, and a plurality of coupling holes, which are coupled elastically with the concavities, are formed in both lateral-wall parts of the air bag door corresponding to the both lateral-wall parts of the upper housing.

2. The air bag module according to claim 1, wherein an external surfaces of the concavities have inclined sections inclined with a predetermined slope along an assembly direction of the air bag door.

3. The air bag module according to claim 1 or 2, further comprising a pair of door retainers coupled with predetermined intervals to inner sides of the both lateral-wall parts of the upper housing.

4. The air bag module according to claim 3, wherein the door retainers have bended sections curved outwardly at the lower portions thereof, and the bended sections are fixed to the inner sides of the both lateral-wall parts of the upper housing by a welding.
