Restraint System for a Motor Vehicle
First Claim
1. Restraint system for a motor vehicle which 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,characterized in thatthe 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
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.

12. Restraint system according to one or several of the previous claims,
characterized in that venting apertures are directed towards the occupant from the enclosed carrier volume, which are covered by the occupant displaced in a forward direction.
-
13. Restraint system according to one or several of the previous claims,
characterized in that the venting apertures are perforations or other passages, which are included in the material enclosing the carrier volume.
-
14. Restraint system according to one or several of the previous claims,
characterized in that one of the supporting structures (7, 8, 9) extends with an at least partial overlap of a hard structure of the motor vehicle, in particular a supporting column.
