PCT No. PCT/DE90/00187 Sec. 371 Date Oct. 25, 1991 Sec. 102(e) Date Oct. 25, 1991 PCT Filed Mar. 15, 1989 PCT Pub. No. WO90/10397 PCT Pub. Date Sep. 20, 1990.A buckle for a safety belt, especially for motor vehicles, for receiving and locking an insertion tongue. A locking latch is provided that is biased in an opening direction and is pivotably mounted in a buckle housing such that in a locking position the locking latch extends into a recess of the insertion tongue. A locking bar is movably mounted in the housing at an angle to an insertion path of the insertion tongue, with the locking bar securing the locking latch in the locking position thereof. A sliding key is guided transverse to a plane of movement of the locking latch for cancelling the locking position thereof via actuation of the locking bar. To protect the buckle from shock, a compensating mass is mounted in the housing such that it is movable relative to the locking bar. The compensating mass serves for fixing the locking bar in position. During acceleration in the same direction as a pushing-in direction of the sliding key, the compensating mass directly supports the locking bar and fixes the position thereof. A spring is supported on the buckle for spring-loading the compensating mass toward a position that fixes the locking bar. |
