Abstract:
A seat-belt system for motor vehicles, comprising:(a) a seat-belt band; (b) an automatic seat-belt winder which winds, and guides the seat-belt band, the automatic seat-belt winder guided in a height-adjustable manner in an essentially vertical sliding guide arranged on a frame of the vehicle; (c) a locking device coupled to the automatic seat-belt winder and the vertical sliding guide which locks the automatic seat-belt winder in a functional initial position in the vertical sliding guide and which releases the automatic seat-belt winder in the event of a collision; (d) a seat-belt tightening mechanism coupled to the automatic seat-belt winder which, when the automatic seat-belt winder is released, displaces the automatic seat-belt winder in the vertical sliding guide in an opposed direction to the direction of the seat-belt band and the tensile forces acting on it due to the collision to tighten the seat-belt band; (e) a seat-belt force limiting mechanism coupled to the seat-belt tightening mechanism which limits the tightening of the seat-belt band brought about by the seat-belt tightening mechanism; and (f) a resetting mechanism coupled to the automatic seat-belt winder which, after the end of the collision and the action caused thereby of tensile forces on the seat-belt band, guides the automatic seat-belt winder back into its functional initial position in the vertical sliding guide where it is locked again.
