Abstract: The invention relates to a device for fixing a gas bag in its folded position. The device comprises a one-piece hollow body, which has a U-shaped cross-sectional profile, a first and a second side wall, a connecting web and a flap section formed on the first side wall. A clip connection is provided by means of which the flap section can be connected with the second side wall having a bracket. Two longitudinal slits are incorporated in the flap section and an elastically flexible closure hook is provided which is separated from the flap section by the two longitudinal slits. The closure hook has a thickened free end which when the body is closed engages behind the bracket formed on the second side wall. Further, the invention relates to a side gas bag module.

Abstract: An inflatable protective cushion to cover side panes of a vehicle in the event of a side impact has a front end and a front anchor point in an area of an A-column and a rear anchor point in an area of a C-column of the vehicle.
