A support apparatus includes a gas-fillable support that is connectable to a gas generator. The gas-fillable support is securable to a body of a motor vehicle and has a first operating state which exists before the gas generator is activated and which has a first volume. The gas-fillable support has a second operating state which exists after the gas generator is activated and which has a second volume which is greater than the first volume. The gas-fillable support in the second operating state is contactable against a first portion which is operationally connected to the body and is contactable against a second portion which is operationally connected to the body and which is remote from the first end portion. A first mechanical strength of the gas-fillable support in the first operating state is less than a second mechanical strength of the gas-fillable support in the second operating state.

An airbag assembly includes an airbag having a knee chamber and an upper chamber. A wall fluidly isolates the knee chamber and the upper chamber. A sleeve extends from the knee chamber through the wall to the upper chamber and fluidly communicates the knee chamber and the upper chamber. A one-way vent is in the sleeve. The one-way vent allows for the knee chamber and the upper chamber to be maintained at different relative pressures.

The invention describes a vehicle occupant restraint system (2) comprising a control unit and at least two restraint elements (8, 10) for the protection of lower extremities (6, 6′, 7, 7′) in the area of a footwell (4) of a vehicle of a vehicle occupant seated in a particular vehicle seat of the vehicle, wherein a first restraint element (8) is configured as a knee airbag module (12), wherein a second restraint element (10) is provided for mounting into the footwell (4) of the vehicle, especially in an area of the footwell (4) of the vehicle arranged in the vehicle longitudinal direction (x) ahead of the knee airbag module (12), wherein, in a situation of restraint, the control unit can differentiate between different given situations, wherein the given situation can be determined via a vehicle seat position and parameters relating to vehicle occupants, wherein, in the situation of restraint, when a situation is given in which the vehicle seat (5) is in a position shifted backwards, especially in a position shifted backwards compared to the standard position, and the vehicle occupant is a short and/or light person, the control unit only activates the foot airbag module (16) of the second restraint element (10).

An airbag device includes an airbag, an inflator and an attachment base. The airbag includes a body portion, and an inflow port portion, into which the distal end side of the inflator is inserted. The attachment base includes a holding plate portion including a pressing portion and a support portion that are provided at positions displaced around an axial center of the inflator so as to surround a periphery of the inflow port portion into which the distal end side of the inflator is inserted. The pressing portion is plastically deformable so as to approach a side of the support portion by being crimped, and the distal end side of the inflator inserted between the pressing portion and the support portion and the inflow port portion are sandwiched between the crimped pressing portion and the support portion, and are held by the attachment base.

The invention describes an airbag module (10), specifically a knee airbag module, comprising at least a module housing (12), an airbag, specifically a knee airbag, and an inflator (16), as well as a holding element (14), the holding element (14) including a seat (18) for the inflator (16) and enclosing the inflator (16) at least partly, in particular in a cage-like manner, the holding element (14) including securing elements (20) at least for securing the holding element (14) and the airbag to the module housing (12), the holding element (14) and/or the module housing (12) comprising a fixing element (24) for fixing the inflator (16) in the holding element (14). The invention further describes a method for replacing an inflator (16) of an airbag module (10).
