A method for producing a valve device is provided. The airbag has at least one substantially air-permeable textile, fabric layer and with a film. The textile layer and the film are arranged in a deep-drawing tool with at least area-wise reciprocal overlapping. The film is deep-drawn in deep-drawing regions by the deep-drawing tool to form a plurality of depressions of the film. The textile layer is connected to the film in regions of the film differing from the deep-drawing regions by the deep-drawing tool.

Method and device for producing a valve unit for an airbag

An airbag for a motor vehicle includes a support structure with a plurality of support elements. The support structure is moveable from a storage position to a support position and by which a support volume of the airbag is covered at least partially in the support position. At least one of the support elements is curved at least in one section in the support position.

Airbag, in particular for a motor vehicle

An airbag for a motor vehicle, having a housing and at least one restraining element, which has at least one receptacle space for a gaseous medium, in particular air, and which can be moved, in the case of an accident-induced application of force to the motor vehicle, into a restraining position by the flowing of medium into the receptacle space from a storage position within the housing. At least one wall of the housing has at least one inflow opening for the medium.

Airbag for a motor vehicle

A restraint system for a motor vehicle unfolds from a storage position to a restraint position. The unfolding is carried out by at least one supporting structure that can be inflated by a gas pressure source; and in the restraining position, the occupant is provided with a carrier volume for restraining the occupant in the displacement position, whereby the carrier volume is enclosed by at least one carrier structure. The dimension of the restraint system is adapted to the respective load condition, and the flexible carrier structure is fixed for enclosing the carrier volume by inflating the supporting structure.

Restraint system

The restraining function of support structure airbags in particular and mechanical airbags should be able to be specifically guaranteed in a simple manner. To this end, an air cushion for an airbag of a motor vehicle is provided, having a sleeve with at least one opening and a closure element arranged on the at least one opening in order to at least partially prevent air from flowing from a first direction, Furthermore, the closure element is flexible and has a channel-shaped design at least upon the flow of air from a second direction opposite the first direction. The closure element thus has the effect of a check valve.

An airbag for a motor vehicle includes a support structure moveable from a storage position into a restraint position and a covering by means of which a restraint volume of the airbag formed by the support structure in its restraint position is surrounded. The covering is formed as an element separate from the support structure and having passage regions in which the covering is at least substantially permeable to air in at least one direction of flow, and connecting regions that are reinforced relative thereto, in which the covering is connected to the support structure.

An airbag for a motor vehicle includes a support structure moveable from a stowage position into a restraint position and a covering that surrounds a restraint volume of the airbag formed by the support structure in its restraint position. The covering is an element that is separate from the support structure and joined to the support structure.

A restraint system for a motor vehicle includes a support structure moveable from a stowage position into a restraint position, a covering by means of which a restraint volume formed by the support structure in its restraint position is enclosed, and at least one ventilation opening via which a medium, in particular air, can flow into the covering during the transfer into the restraint position. The at least one ventilation opening is provided within a housing that at least partially accommodates the support structure and the covering in the stowage position.

Restraining system, in particular for a motor vehicle

A valve device for a gaseous medium of an airbag is provided. The valve device includes a textile layer, in particular a woven fabric, which is permeable with respect to the medium at least in certain regions. The valve device also includes at least one film covering the textile layer in at least one region and which forms at least one passage region of the valve device, which is at least substantially closed in a closed position of the valve device and open at least in certain regions in an at least temporary passage position of the valve device.

Valve device for a medium and airbag for a motor vehicle

A restraint device for a motor vehicle includes a support structure with a plurality of structural elements in which the support structure can be moved from a stowage position into a restraint position. The restraint device also includes a covering by means of which a restraint volume formed by the support structure in its restraint position is surrounded. At least one support element is provided by means of which at least one of the structural elements of the support structure is held in a predetermined form and/or position at least in the restraint position.

Restraint device, in particular for a motor vehicle

An airbag with a valve device for a gaseous medium includes at least one textile layer and at least one foil that at least partially covers the textile layer such that due to the valve device at least one area of the airbag permeable by the medium can be at least partially opened when the valve device is in an open position and can be at least substantially sealed when the valve device is in a closed position.

Airbag and method for producing such an airbag

An airbag for a motor vehicle, comprises a support structure that can be displaced from a storage position to a restraint position, and a covering which surrounds a restraint volume of the airbag formed by the support structure in its restraint position. At least one connecting element, which extends inside the restraint volume, connects together the hollow bodies of the support structure and/or the surface areas of the covering.

A valve mechanism for a gaseous medium of an airbag is provided. The valve mechanism includes a first and second layer, which respectively include a passage opening that is substantially closed in a closed position of the valve mechanism by a corresponding cover region of the other respective layer. An adjusting element in the form of a tube with an adjustable volume provides a temporary passage position of the valve mechanism by lifting one of the cover regions of the corresponding layer from the corresponding passage opening.

Valve device and airbag comprising such a valve device, and method for operating such a valve device

A vehicle occupant restraint system has an airbag, which provides a predetermined support force distribution in the filled (unfolded) state, and at least one energy-absorbing element that is attached to the airbag in order to unfold it or to locally increase the support force thereof. The energy-absorbing element(s) are arranged such that at least one energy absorbing element may apply itself to an occupant, and may at least partially follow the movements of the same at least to a certain extent. The energy-absorbing element has an occupant-protective function, and/or the airbag has a funnel function relative to an occupant to be supported. The occupant is guided toward the center of the airbag during an impact by means of the funnel function, and is possibly also protected laterally by means of the side walls.

Vehicle occupant safety system with energy-absorbing elements, and method of operating same

A restraint system having support elements can be transferred from a storage position to a restraint position. Flexible casing elements are disposed between the support elements and have air flow openings, such that the support elements having the flexible casing elements enclose a restraint volume in the restraint position. A resistance element is disposed at each of the air flow openings in order to impede or prevent the escape of air from the restraint volume compared to the inflow at the respective air flow opening. Such resistance elements may be formed by a second layer, displaced fabric threads, flexible fabric web sections and other elements such that a check valve function is provided.
