A plurality of curved nicks is provided in the wall of the gas bag. Each of the curved nicks determines an emission orifice for the pressurized gas.

Abstract: Belt webbing designed for a vehicle occupant restraining system, which is to replace conventional force limiting means leading to added structural complexity and additional costs and which may be possibly incorrectly fitted in place, is characterized in that the warp threads (7) possess lengths differing with each length unit of the belt webbing, that is to say in the form of short warp threads (10) to bear the tensile load acting in the belt webbing (1) up to a first stretch of the belt webbing (1) without loading the longer warp threads and in the form of longer warp threads, which after the first stretch of the belt webbing (1) take part in withstanding the tensile load acting in the belt webbing (1) in a manner dependent on the ratio of the length thereof to the length of the short warp threads (10).

Abstract: A vehicle seat with an integrated belt tensioner secured thereto comprises a seat part, a seat frame and a connection element to connect the piston of the belt tensioner to the safety belt. The tube of the belt tensioner is curved transversely to its longitudinal extent and is substantially adapted to the outer contour of the side wall in the region of the side wall of the seat part so that the belt tensioner only slightly projects from the side of the vehicle seat. In addition, due to the curved tube a relatively long tensioning path results.
