Abstract
Abstract A buckle for safety belts including latch means for releasably connecting the buckle to a first webbing, adjustment means for adjustably securing the buckle to a second webbing thereby allowing the webbing to be cinched, and spring means which cooperates with both the latch and adjustment means. The spring means cooperates with the latch means to spring bias the latch means so as to releasably secure an end plate of the first webbing to the buckle. The spring means cooperates with the adjustment means so as to releasably secure it to the buckle. In a modified embodiment of the present invention, the spring means is replaced by a diverse functional member which, firstly, cooperates with the adjustment means so as to releasably secure it to the buckle, secondly, functions as an ejector device to positively eject the end plate of the first webbing from the buckle when the end plate is unlatched, thirdly, prevents inadvertent movement and rattle of the end plate of the first webbing when the latter is in its latched position, and fourthly, supports the latch lever.
