PCT No. PCT/SE80/00065 Sec. 371 Date Nov. 5, 1980 Sec. 102(e) Date Nov. 5, 1980 PCT Filed Mar. 5, 1980 PCT Pub. No. WO80/01877 PCT Pub. Date Sep. 18, 1980.A locking mechanism for safety belts of the reel belt type and provided with a strap webbing (3), which can be unwound from a strap reel and a pawl mechanism (8), which is changeable between a position releasing the strap reel and a locking position. The device also comprises an activating mechanism (7) for the change-over of the pawl mechanism to a locked position. The activating mechanism has a body (11) of inertia with a determined basal surface (14). The body of inertia can occupy a central rest position with a basal surface resting on a carrying surface (19), or a peripheral activated position, in which the body of inertia is tilted about a first pivoting center (45). The activating mechanism also has a transmission element (12) which is provided to sense the positions of the body of inertia and to change-over the pawl mechanism (8). The activating mechanism (7) has a second pivoting center (44), about which the transmission element is arranged to pivot in connection with the change-over of the body (11) of inertia between the rest position and the activated position. The transmission element is provided with a shank (33), which in the rest position occupies a centric position relative to the axis of symmetry of the body of inertia. The same is arranged to cooperate in a third pivoting center (46) for the activating mechanism (7) with its end with a guide surface (35) in the body of inertia in such a manner that the end of the shank is moved sideways by the body of inertia when the same is moved to its activated position. |
