Impact-protected safety belt buckle

A safety belt buckle comprises a housing with an insertion path, a spring loaded ejector positioned in the insertion path, and a recess communicating with the insertion path. An insertion tongue with a cutout is insertable into the insertion path. A latch inside the housing locks the insertion tongue by engaging the cutout of the insertion tongue and the recess of the housing. A spring-loaded slide key is slidably connected to the housing and slidable in the direction transverse to a plane of movement of the latch. A spring-loaded slide key serves to release the latch. A compensation mass member is displaceably arranged within the housing for compensating acceleration forces acting on the safety belt buckle. A securing element is displaceably arranged within the housing such that the securing element secures the latch in its locking position and is movable into a release position by the slide key. The compensation mass member and the securing element are connected by a connecting rod arrangement with a scissor-type movement. The connecting rod arrangement is comprised of two connecting rods and a journal point at the housing. Due to the connecting rod arrangement, the compensation mass member and the securing element move in opposite directions relative to one another.

Safety belt buckle with anti-shock device

With a safety belt fastener for the take-up and latching of an insertion tongue having a housing and an insertion path for the insertion tongue, the insertion path being arranged in the housing and containing an ejector under spring action, having a latch guided in the fastener and cooperating with the tongue recess in the case of latching, the latch holding the insertion tongue in an associated recess of the fastener, and a spring-loaded shift key, guided at right angles to the movement plane of the latch, for the lifting of the latching device, the movement of which is composed of an unlatching stroke and a preceding idle stroke, simple anti-shock means are realized by providing in addition to the shift-key spring a further additional spring supported between a fastener part and the shift key, aligned in its spring force to oppose the insertion direction of the shift key and only active during the idle stroke of the shift key.
