Grip for disassembling receiving sheath in sliding motion from assembly rod of automobile head-rest of vehicle seat, has cam elements cooperating with reciprocal elements to make passage of jaws from loosened to tightened configurations

摘要

The grip (1) has jaws (5) mounted in rotation on a plate so as to confer between a loosened configuration and a tightened configuration. A movable branch (7) is mounted in rotation relative to the plate so as to actuate between isolated position and closer position of a fixed branch. Cam elements are interdependent of the movable branch. The cam elements cooperate with reciprocal elements provided on the jaws to make passage of the jaws from the loosened configuration to the tightened configuration when the movable branch is actuated from its isolated position to its closer position.
