Abstract

Disclosed is a vehicle seat with a side airbag, which includes an airbag module with an airbag cushion accommodated therein; a seat back frame with the airbag module mounted thereto; and a seat back pad provided with bolsters protruding forward at opposite sides thereof, with an accommodation space being formed in an outboard one of the bolsters by coupling the outboard bolster to the seat back frame, thereby allowing the airbag module to be accommodated therein, wherein the seat back pad includes a body part, and a guide part formed in an inboard portion of an inner surface of the outboard bolster to guide deployment of the airbag cushion, and the body part and the guide part are made of materials having different rigidity from each other.

First claim

What is claimed is:

1 . A vehicle seat with a side airbag, the vehicle seat comprising:
an airbag module with an airbag cushion accommodated therein; a seat back frame with the airbag module mounted thereto; and a seat back pad provided with bolsters protruding forward at opposite sides thereof, with an accommodation space being formed in an outboard one of the bolsters by coupling the outboard bolster to the seat back frame, thereby allowing the airbag module to be accommodated therein, wherein the seat back pad includes: a body part; and a guide part formed in an inboard portion of an inner surface of the outboard bolster to guide deployment of the airbag cushion, and the body part and the guide part are made of materials having different rigidity from each other.
