<p>Locking device for safety belts of the reel-belt type preferably intended for vehicles and provided with a band, which against the bias of a spring can be unwound from a rotating bandreel. The device comprises a ratchet wheel which normally rotates with the reel and a pawl mechanism with a pawl for cooperation with the ratchet wheel. The pawl can be switched between a position, in which it releases the ratchet wheel, and a locking position, in which it engages the ratchet wheel in order to impede its rotation in one direction. The device further comprises an activating means, which is arranged on one hand to occupy an activated condition and on the other hand to occupy an inactive condition and depending upon its condition to actuate the pawl mechanism for shifting of the pawl between its releasing and its locking position. The activating means comprises a body of inertia, which is adapted under the influence of forces of inertia to be shifted from a rest position to an activated position, and a transmission element, which is designed to sense the position of the body of inertia and in dependence thereof to actuate the pawl. The transmission element and the body of inertia are supported by separate supports. The transmission element is in cooperation with the body of inertia shiftable between an activated position and a rest position under the influence of return forces.</p> |
