ABSTRACT:
A fastening mechanism for a safety belt comprising a locking tongue attached to one end of a safety belt and a locking case attached to the other end of the safety belt. The case pivotably supports a locking flap which selectively engages the locking tongue to lock the same in the case or to release the locking tongue. A spring acts on the locking flap to urge the same to a locking position in which the locking tongue is engaged by the locking flap. An expeller is mounted in the case for displacement to expel the tongue from the case when the tongue has been released from the locking flap. A push button including an integral cam has a cam surface on which the locking flap is engaged under the action of the spring and displacement of the push botton displaces the cam and moves the locking flap to a release position with respect to the tongue. The cam has a slot in which the locking flap is engaged in the locking position and when the push button is displaced the locking flap rises up on the cam surface to release the locking flap and concurrently projections on the expeller pass beneath the raised locking flap to support the locking flap while the tongue is being expelled by the expeller.
