Abstract: A gas bag module for a vehicle occupant restraint system has a generally trough-shaped housing, a folded gas bag and an insert for insertion into the housing. The housing has a face wall with an opening. The gas bag module further comprises a tubular inflator. The tubular inflator is inserted into the housing through the opening in the face wall of the housing. The housing has an inner side with supporting faces for the insert. The insert has integral rim portions surrounded by an inflation opening in the gas bag. The insert is provided with an integral guide plate extending substantially parallel to inner surface areas of the housing and slightly spaced away therefrom. The insert comprises, opposite the opening in the face wall of the housing, a corresponding opening for passage of the inflator. The inflator protrudes outwardly from the opening in the face wall of the housing. The insert is clamped at the rim portions against the supporting faces of the housing.

Abstract: A belt tensioner, more particularly a buckle tensioner for a vehicle occupant restraint system comprises a housing, a gas generator, a working space (15) into which the pressurized gas released in a restraint situation flows, a piston part (9) which is displaceable in the working space (15) by the pressurized gas, a belt engagement apparatus, and a traction transfer, apparatus (7) which connects the belt engagement apparatus with the piston part (9). A housing-fixed deflection apparatus (21) provided in the working space guides the stream of pressurized gas away from the traction transfer apparatus (7) and prevents the pressurized gas which flows out of the gas generator from directly impinging on the traction transfer apparatus (7), with the result that the thermal stress on the traction transfer apparatus (7) is less than with conventional belt tensioners.

The belt pretensioner displaces the belt link element via the tension transmission element in the event of a collision upon actuation of the belt pretensioner, so that the tubular body penetrates into the a curved guide and is bent.

Abstract: A method of folding a side impact gas bag comprises the following steps: First, the gas bag is spread out on a base. Then, the rim of the inflation opening of the gas bag is fixed. Thereafter, a plate is arranged at a predetermined distance from the base and parallel thereto, so that the gas bag lies between the base and the plate. Then, the gas bag is inflated between the base and the plate. Finally, the wall of the gas bag is pushed together from the outside inwards, whereby a portion of the wall of the gas bag is turned into its interior.
