Airbag apparatus
First Claim
1. An airbag apparatus adapted to be mounted on a vehicle as housed in a housing, the apparatus comprising an airbag inflatable with inflation gas for catching an object of protection, the airbag comprising a sheet-shaped circumferential wall made from thermoplastic synthetic resin,wherein the circumferential wall is plastically deformable in such a manner as to be elongated due to increase of internal pressure caused by being pressed by the object of protection when arresting the object of protection after full inflation, andwherein the airbag is configured to complete inflation at or under a tensile stress at yield point of the thermoplastic synthetic resin that forms the circumferential wall of the airbag.

Abstract
An airbag apparatus is mounted on a vehicle as housed in a housing and includes an airbag inflatable with inflation gas for catching an object of protection. The airbag includes a sheet-shaped circumferential wall made from synthetic resin. The circumferential wall is plastically deformable in such a manner as to be elongated due to increase of internal pressure caused by being pressed by the object of protection when arresting the object of protection at full inflation.

9. An airbag apparatus adapted to be mounted on a vehicle as housed in a housing, the apparatus comprising an airbag inflatable with inflation gas for catching an object of protection, the airbag comprising a sheet-shaped circumferential wall made from thermoplastic synthetic resin, wherein
the circumferential wall is plastically deformable in such a manner as to be elongated due to increase of internal pressure caused by being pressed by the object of protection when arresting the object of projection after full inflation and, the airbag has no vent mechanisms for exhausting inflation gas.

10. An airbag apparatus mounted in a vehicle, the apparatus comprising an airbag inflatable with inflation gas for catching an object of protection, the airbag having a circumferential wall that is arranged adjacent the object of protection, the circumferential wall being an outside wall of the bag and being made from sheet-shaped material,
wherein during full inflation of the airbag, the circumferential wall is configured to plastically deform and permanently enlarge by increasing internal pressure within the airbag that is generated by inflation gas and by the object of protection pressing against the airbag, and wherein the airbag is configured to complete inflation at or under a tensile stress at yield point and below a tensile stress at rupture of a synthetic resin that forms the circumferential wall of the airbag.
