Gas bag
First Claim
1. A gas bag for a vehicle occupant restraint system, withseveral walls of layers of fabric, which delimit the interior of said gas bag, adjacent walls being connected in one piece with each other by interweaving, with an outer periphery along which said walls are connected to each other by interweaving, and with several chambers which are separated from each other by the provision of an elongated, interwoven region, wherein said interwoven region provided for separating chambers having opposite ends and terminates at least at one of said ends at a distance from said interwoven outer periphery, in order to delimit at least one overflow channel in the region of said outer periphery of said gas bag, and said interwoven region running out in at least one of a rounding and a drop shape at said end terminating at a distance from said outer periphery.

Abstract
A gas bag has several walls of layers of fabric, which delimit the interior of said gas bag, adjacent walls being connected in one piece with each other by interweaving, and an outer periphery along which said walls are connected to each other by interweaving, and several chambers which are separated from each other by the provision of an elongated, interwoven region. The interwoven region provided for separating chambers has opposite ends and terminates at least at one of said ends at a distance from said interwoven outer periphery, in order to delimit at least one overflow channel in the region of said outer periphery of said gas bag. The interwoven region runs out in at least one of a rounding and a drop shape at the end terminating at a distance from the outer periphery.
