Abstract:
A coupling device for a seat belt retractor comprisinga) a driven member connected to a belt reel of the seat belt retractor;b) a rotatable driving member for transmitting torque to the driven member, wherein the torque results in the belt reel rotating in a winding direction;c) a coupling element having a substantially semicircular shape mounted on the driving member, the coupling element is held in a disengaged state by a spring force, the coupling element is mounted with its center of gravity outside the axis of rotation of the driving member;d) a guide means for guiding the coupling element to an engaged state with the driven member;e) two support points on the driving member that support the coupling element in the engaged position, said support points are diametrically opposed with respect to the axis of rotation; andwherein the first support point is formed between two stop faces, and the second support point formed by two support faces, one support face is provided on the driving member and the other support face is provided on the coupling element.
