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.
Claims11
A restraint system for a motor vehicle that unfolds from a storage position into a restraining position, wherein the restraint system comprises:
- first, second, and third supporting structures, each of which has a longitudinal extension in a deployed state that substantially exceeds a transverse extension, and each of which unfolds mainly in a direction of the longitudinal extension;
- and
- a flexible carrier structure connected between the first, second and third supporting structures and enclosing a carrier volume,
- wherein the first, second, and third supporting structures have substantially a same shape in the deployed state,
- wherein the first and second supporting structures each have an inlet coupled to receive gas from an external source, and the third supporting structure is configured to receive gas from the external source via connections with the first and second supporting structures,
- wherein in the deployed state the first and second supporting structures extend in a longitudinal direction of the motor vehicle and the third supporting structure extends in a transverse direction of the motor vehicle between the first and second supporting structures, and
- wherein the third supporting structure is configured along a length of the first and second supporting structures such that in the deployed state projecting portions with free terminal ends of the first and second supporting structures extend beyond the connections with the third supporting structure to form an open space receiving an occupant of the motor vehicle.
