<p>The surface (14 15) of the swivel bolt (13) and locking tonque (10) of the safety belt lock contact each other in the locking position. They have matching arcuate shapes. The radius (R) of the arcuate section is equal to the distance between the touching faces (14 15) and the swivel axis (K) of the bolt (13). The contour of the tonque and bolt is such that these two parts can slide away from each other during the unlocking movement without the tonque having to perform a negative stroke thus moving into the lock housing (12) when the bolt is swivelled inwards before it can move out of the housing of the lock.</p> |
