A vehicle seat belt buckle has a socket part with a socket and a latch member for latching a tongue part within the socket. The latch member is held in the latching position by a catch element movable manually to release the latch member by means of a push button to which the catch element is connected either directly or by a lost motion connection. The latch member then rotates to a release position for the tongue under a spring bias, a portion of the latch member positively ejecting the tongue. Instead, the latch member is rotated by the tongue to a release position in which the catch element applies a holding bias overcome by the tongue on reinsertion. In a third arrangement, the catch element is rolled against bias on a profiled surface of the latch member to tilt this to a release position in which it is held by an ejector until the tongue is reinserted. |
