Abstract: A knee airbag for a vehicle occupant restraint device can adopt a deployed position of use between a fixed vehicle component and the legs of a vehicle occupant. The airbag includes an airbag sheath, at least one exhaust orifice formed therein and control features for selectively releasing the exhaust orifice. The control features are disposed inside the knee airbag and arranged so as to release or block the exhaust orifice depending on the expansion of the knee airbag in a particular direction of expansion.

Abstract: A vehicle occupant restraint device having a knee airbag deployable between an instrument panel and the legs of a vehicle occupant and including an airbag sheath and at least one exhaust orifice formed therein. The vehicle occupant restraint device further has features for qualifying the build of the vehicle occupant, an activating unit for selectively releasing the exhaust orifice and a control which actuates the activating unit depending on the qualification of the build of the vehicle occupant.

Abstract: A vehicle occupant restraint device comprises a knee airbag (10) deployable between an instrument panel (32) and the legs of a vehicle occupant and including an airbag sheath (14) and at least one exhaust orifice (18) formed therein. The vehicle occupant restraint device further comprises a means for qualifying the build of the vehicle occupant, an activating unit (24) for selectively releasing the exhaust orifice (18) and a control means which actuates the activating unit (24) depending on the qualification of the build of the vehicle occupant.

Abstract: A vehicle occupant restraint system comprises an inflatable knee airbag (10). The knee airbag (10) includes an airbag sheath (12) and at least one vent hole (18) formed therein. The vent hole (18) is arranged in the upper half of the knee airbag (10) and is provided on a side of the knee airbag (10) facing away from the vehicle occupant which in the operating position of the knee airbag (10) is directly opposed to a fixed component (28) in the vehicle interior.

Abstract: A knee airbag (10) for a vehicle occupant restraint device can adopt a deployed position of use between a fixed vehicle component (12) and the legs (14; 16) of a vehicle occupant. The knee airbag (10) comprises an airbag sheath (18), at least one exhaust orifice (20) formed therein and a control means for selectively releasing the exhaust orifice (20). The control means is disposed inside the knee airbag (10) and is arranged so as to release or block the exhaust orifice (20) depending on the expansion of the knee airbag (10) in a particular direction of expansion.

Abstract: The invention relates to an airbag (12) of a vehicle occupant restraint system (10) comprising plural juxtaposed compartments (16) delimited outwardly by opposing external walls (18) and against each other by partitions (20), wherein the airbag (12), in the inflated condition, has a form overall bent and elongate in cross-section. In the bending area the external wall (18) includes a cut-out (22) that is closed by an inserted insert (24) tensioned in the deployed condition which in the longitudinal direction has a length (LE) different in the bending area from the opposing external wall portion (28) of the chamber (16) so as to produce the bending. The invention furthermore relates to a method of manufacturing an airbag of this type.

Abstract: A vehicle occupant restraint system comprises an airbag module (16) disposed in an instrument panel (14) the airbag (18) of which extends when inflated from a receipt in the instrument panel (14) into the interior of the vehicle (10). A supporting structure (20) for the airbag (18) on a side of the airbag (18) facing a windscreen (12) is configured so that it supports the airbag (18) against the forces occurring when a vehicle occupant immerses in the airbag (18).

Abstract: A vehicle occupant restraint device has a gas bag module with a housing and a gas bag having a free exit end, the gas bag moving into its fully deployed position with the free exit end first. At least one control element is provided which engages the gas bag and forces the gas bag to extend generally in an arc shape from the housing up to the free exit end in the deployed state.

Abstract: A gas bag module for a vehicle occupant restraint system has a gas bag, a gas generator being in flow connection with the gas bag, and at least one cover part adapted to cover the gas bag against a passenger compartment when the gas bag module is mounted in a vehicle. The cover part has a hinge portion which allows the cover part to pivot from a closed condition into an opened condition in which the gas bag is able to exit from the gas bag module, and further having an edge opposite the hinge portion. At least one traction transfer device is provided which has a first and a second end and is adapted to exert a tensile force on the cover part after activation of the gas generator. The first end of the traction transfer device is attached to the edge of the cover part so that the cover part opens in a direction towards the gas bag due to the tensile force exerted by the traction transfer device.
