1. A restraint system for a motor vehicle comprising:
- 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,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 the gas from the external source via the first and second supporting structures,wherein at least one of the following is true;
when at least the first and second supporting structures impact upon an obstacle prior to being completely unfolded, the first and second supporting structures do not have a same stability as when the first and second supporting structures are completely unfolded; and
when at least the first and second supporting structures impact upon an obstacle prior to being completely unfolded, the first and second supporting structures do not reach a final volume or a final extension,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,wherein the third supporting structure is configured along a length of the first and second supporting structures such that the first, second and third supporting structures form an A shape.

Abstract
A restraint system for a motor vehicle is formed by one or more inflatable supporting structures whose longitudinal extent in the deployed state substantially exceeds their transverse dimension, and which unfold mainly in the direction of their longitudinal extension. During unfolding, the supporting structure, when impacting upon an obstacle does not have the same stability as when it is completely unfolded, and/or does not reach the final volume or the final extension.

16. A vehicle restraint system comprising:
-
first, second, and third inflatable supporting structures, wherein said first, second, and third supporting structures have substantially a same shape a in the deployed state; said 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 the gas from the external source via the first and second supporting structures, said first, second, and third supporting structures each has a longitudinal dimension that substantially exceeds a transverse dimension; said first, second, and third supporting structures are each deployable from an uninflated storage position to an inflated operational position; in said uninflated storage position, said first, second, and third supporting structures are each rolled up or folded along the longitudinal dimension, so that during inflation, each of the first, second, and third supporting structures unrolls or unfolds longitudinally into a substantially tubular configuration; and when at least one of the first, second, and third supporting structures impacts an obstacle during inflation, further inflation and unrolling of said at least one of the first, second, and third supporting structures is precluded, 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, wherein the third supporting structure is configured along a length of the first and second supporting structures such that the first, second and third supporting structures form an A shape.
