Abstract
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.
