Abstract: A force-limiting device (4) for a seat belt device having at least two parts (5, 11, 15) controlled with a frequency-dependent, defined movement for energy absorption, wherein the parts (5, 11, 15) that move the parts (5, 11, 15) undergo an undulating movement (Q) directed perpendicular to the feed movement (V) in the course of which the gearings (8, 10, 18, 19) alternatingly engage and disengage. An open spring washer exerts force to move the parts (5, 11, 15) toward one another and can be automatically increased after a preset belt extraction length. The spring washer (6) applies a varying spring force to the parts (5, 11, 15) moving toward one another during the movement.

Abstract: A seat belt retractor including a belt shaft rotatably supported in a frame and two force-limiting devices acting in parallel. The first and the second part of the belt shaft axially overlap forming an annular space. The second force-limiting device is a band element abutting a radial outer wall of the annular space with a first section, and on the radial inner wall with a second section and is deflected in a deflection fitting between the first and the second sections (20, 21, 29, 30). During relative movement between the first and second parts, the band element can be unwound or wound up from the outer wall onto the inner wall or vice versa in an energy-dissipating manner.

The safety belt winder has an integrated force limiting device for the safety belt force occurring in the belt webbing on locking the safety belt winder.

Abstract: A securement arrangement for a seat belt closure of a three-point seat belt system in a vehicle comprises an anchor piece secured to the vehicle, a closure body, and a generally U-shaped closure body retaining assembly for mounting the closure body on the anchor piece. A spring disposed between a pair of U-forming legs of the closure body retaining assembly biases the closure body into its home position. A contact element emits a signal to be processed by an onboard signal processing unit when the closure body, due to the application thereto of a load imposed by the seat belt, is displaced so as to overcome the biasing force of the spring. The contact element correspondingly moves out of contact and emits a signal in response to its movement out of contact.
