ABSTRACT:
A safety belt fastening in which the male member includes an enlarged head for laterally pivoting a spring biased locking member operating in a recess of at least one of two plates joined to form the female member of the fastening. The locking member moves to a position aligned substantially with the insertion movement of the head until the head passes. A guide surface including a pin in the female member laterally displaces the male member at an incline to cause pivotal rotation of the locking member during insertion, thereby effecting a force economy compared with that effected by a straight in insertion. When the locking member rotates, it pivots about its rear face in conjunction with an oppositely aligned recess face in a bearing-like action, at least one of these faces being convex. Preferably, the rear face of the locking member is made of drawn steel. The locking member is manually rotatable for release. An injector spring separates the male and female members at the time of release.
