Abstract
A buckle adapted to receive and retain a tongue mounted on a safety belt includes an actuating member mounted for rotation about a first predetermined axis to and from a latch position, the actuating member having an engaging portion, and a latching member mounted for rotation about a second predetermined axis. The latching member is movable between a first, latching position in which the latching member or a latching component driven thereby engages a tongue to retain the tongue latched in the buckle and a second, release position in which the tongue may be released from or introduced into the buckle. The actuating member and the latching member are mechanically interconnected so that rotation of the actuating member causes rotation of the latching member, and the latching member has an abutment portion for engagement with the engaging portion of the actuating member for retaining the latching member in the first, latching position such that the actuating member must move from the latch position before the latching member can be moved to the release position. The angular moments of inertia of the actuating member and the latching member about their axes of rotation are such that, …
