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;
a seat back frame; and
a seat back pad comprising a bolster;
the bolster comprising an inboard portion and an outboard portion;
an accommodation space located inside the bolster for accommodating the airbag module therein; and
a guide part disposed on an inner side of the inboard portion and made of a material that is more rigid than a material of the inboard portion of the bolster,
wherein the guide part comprises a contact portion that contacts the airbag module and a non-contact portion that does not contact the airbag module,
wherein the non-contact portion extends from the contact portion to form a gap between the airbag module and the non-contact portion of the guide part as part of the accommodation space such that the gap increases along at least part of an extension of the non-contact portion from the contact portion.

2. The vehicle seat of claim 1 , wherein the guide part is made of one selected from a group consisting of polyurethane, polystyrene, polyolefin, polyethylene, polypropylene, phenol resin, polyvinyl chloride, urea resin, silicone, polyimide, melamine resin and a combination thereof.

3. The vehicle seat of claim 1 , wherein the seat back pad and the guide part are integrally formed.

4. The vehicle seat of claim 1 , wherein the seat back pad is configured such that the accommodation space comprises a channel extending along a deployment direction of the airbag module.
