PCT No. PCT/GB95/01065 Sec. 371 Date Apr. 14, 1997 Sec. 102(e) Date Apr. 14, 1997 PCT Filed May 10, 1995 PCT Pub. No. WO95/30347 PCT Pub. Date Nov. 16, 1995A buckle mechanism for use in vehicle safety restraint systems which is substantially shock proof against forces in many directions in a crash situation and also against forces generated by buckle pretensioners used to take up the slack in the belt webbing. The buckle mechanism has a movable button and a resiliently biased locking member guided by a rocking support member and movable transversely to the plane of movement of the button to engage or disengage a locking surface of a co-operating tongue. Mutually co-operating abutments are provided respectively on the button and on the locking member or on the rocking support member to lock the button against the buckle disengaging forces of a crash situation. Preferably an overlocking member is also provided to further resist spurious disengagement of the buckle. |
