摘要

Seat belt retaining device such as a self-locking belt roller or an end mounting tightener comprises a force-limiting device consisting of a wire-like deformation element (16) extending through a belt shaft (12) perpendicular to the longitudinal axis of the belt shaft. The ends (18) of the deformation element located on both sides of the passage through the belt shaft formed in an axial shaft attachment (15) are wound on take-off rollers (19) and on rotation of the belt shaft in the force-limiting direction they are unwound from the take-off rollers onto the shaft attachment in a counter-rotating manner. Preferred Features: The deformation element has a constant cross-section over its entire length.
