ABSTRACT:
A separable buckle (such as a seat belt buckle for occupants of vehicles) adapted to connect two separable belts. A first structural member in the form of a floating link is typically secured permanently to one end of a first belt. A second structural member is adapted to be permanently secured to the end of the other belt. Permanently attached to the second structural member is a lever which is pivotable about a control axis near the distal end of said second structural member. The control axis is preferably elevated above the plane defined by the remote ends of the two structural members. At an intermediate position along the lever is provided an open-face cusp, which is adapted to receive the distal end of the floating link. In latching the buckle, the lever is rotated to an extended position, and the distal end of the floating link is rested against the cusp. By rotating the lever through about 180.degree. to a folded condition alongside the second structural member, the floating link is drawn toward the second structural member. By causing the lever to rotate "over-center", the buckle becomes essentially self-latching. Means are also provided for securing auxilliary straps, such as shoulder straps or leg straps, to the buckle when it is latched.
