Abstract: An airbag module has an airbag and a gas generator. A supporting element is arranged between the gas generator and the airbag in the direction of deployment of the airbag such that, when folded, a portion of the airbag which is at the front in the direction of deployment rests essentially flat against a front surface of the supporting element.

Abstract: An apparatus for tensioning a seatbelt has a piston that is driven in a guide tube and is connected to the belt webbing of the seatbelt via a traction cable and with a cable guide for the traction cable. The traction cable acts on one end of the belt webbing of the seatbelt and is looped around the cable guide 180°. The portion of traction cable extending between the cable guide and the belt webbing is guided substantially parallel to the axial direction of the guide tube.

Abstract: A spool for a seat belt retractor has a cylindrical member with a cylindrical central portion and two end plates at opposite axial ends of the cylindrical portion. There is a channel formed in the cylindrical central portion with an outer and an inner wall and defining a path for guiding seat belt webbing. The path circumscribes the spool axis substantially over the length of the central portion of the spool in a generally smooth curve. The path has a spool entry and a spool exit portion and an acute angle subtended at the spool axis by the entry portion of the path and the exit portion of the path is approximately 90°. The spool may be hollow with a torsion bar forming the inner wall of the channel.
