Abstract

A tightener for safety belt reeling means has a cable 14 arranged to be actuated in the event of a crash to turn a cable reel 11 connectible in form-locking manner via a locking member 20 to coupling teeth 12 of a belt winding shaft of the belt reeling means. The locking member 20 is arranged on the cable reel 11 and is radially movable in order to engage in the coupling teeth 12 provided on the belt winding shaft. In order for the operation of the locking member 20 to take place independently of the rotational acceleration of the cable reel 11, a control element 15 is provided, which is movable relative to the cable reel 11 to act on bell-crank lever 25 and thereby cause the locking member 20 to deflect to the locking position. The control element 15 is moved by the straightening of a bent portion 18 of the reel cable 14 in the event of an accident. <IMAGE>
