Abstract

A side gas bag for a vehicle occupant restraint system includes an inflatable volume which is delimited by an exterior gas bag covering (16). There is provided an inflatable pouch (18) in the inflation region of the gas bag (14) inside the gas bag covering (16). There is further proposed a side gas bag module including such side gas bag.

Claims

1. A side gas bag for a vehicle occupant restraint system, said side gas bag having an inflatable volume which is delimited by an exterior gas bag covering (16), characterized in that there is provided an inflatable pouch (18) in an inflation region of said gas bag (14) inside said gas bag covering (16).

2. The side gas bag according to claim 1, characterized in that said pouch (18) has an elongated, tubular shape with a first end (20) constructed as an inflation opening, and a second end (22) constructed as an outflow opening.

3. The side gas bag according to claim 1, characterized in that said pouch (18) is provided with a tear seam (24), which tears open at a predetermined internal pressure of said pouch (18) and thereby frees an outflow opening.

4. The side gas bag according to claim 3 characterized in that said tear seam (24) has at least one exhaust opening.

5. A side gas bag module for a vehicle occupant restraint system, characterized in that said module (10) has at least one side gas bag (14) including an inflatable volume which is delimited by an exterior gas bag covering (16) and including an inflatable pouch (18) in an inflation region of said gas bag (14) inside said gas bag covering (16).

6. The side gas bag module according to claim 5, characterized in that said pouch (18) of said side gas bag (14) is directly connected with an inflation connection (12) of said module (10).
