Abstract
A vehicle seat belt tensioner comprises a traction element that transmits a tensioning force to a seat belt strap. The traction element may be formed for example of a flexible rope or a wire, or a thrust element which can transmit traction and thrust forces. A force limiting unit, which limits the retaining force exerted by the seat belt strap on a passenger has a functional element coupled to the traction or thrust element, which is displaceable by means of a displaceable piston element in the effective direction of the tensioning force. The vehicle belt tensioner according to the invention includes means for the parallel application of tensioning force to both the piston element and the traction or thrust element, concurrently.
