Abstract:
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.
Abstract:
The invention relates to a restraint system for a motor vehicle that is formed by one or several supporting structures, wherein the longitudinal extension of a supporting structure in the active state substantially exceeds the dimensions of the transverse extension and the supporting structure unfolds mainly in the direction of its longitudinal extension. So as to improve the restraint system such that the variables of the restraint system are adapted to the respective load, it is suggested that, during unfolding, the supporting structure (7, 8, 9), when impacting upon an obstacle (5), does not have the same stability as when it is completely unfolded, and/or does not reach the final volume or the final extension.
Abstract:
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.
Abstract:
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.
Abstract:
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.
Abstract:
A support structure for a vehicle airbag that can be displaced from a storage position to a restraint position by a gas flow, comprises a plurality of hollow bodies that are connected to each other to form a channel system. A device is provided inside the channel system for the targeted influencing of the gas flow.
Abstract:
An air bag is provided with a air cushion formed of one woven fabric. At least one functional element, which provides the airbag with an additional function, is woven into the air cushion in one piece. The functional element can be a tube system of a support structure airbag and/or a valve for unfolding of a support structure airbag.
Abstract:
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.
Abstract:
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.
