Control mechanism for lock pawl

A control mechanism for a lock, the control mechanism comprising an electric motor mounted in a housing that is connected with the seat backrest, the electric motor having an output shaft with a worm gear, the worm gear engaging with the spur gearing of a transmission gear, the transmission gear rotary-mounted on a transmission pivot and having on its frontal surface an eccentric selector pivot for controlling the pawl of the lock, the pawl mounted on a pawl pivot for swinging between a blocking position, in which the pawl blocks a rotary ratchet of the lock from releasing a catch eye connected with the car bodywork, and an unlocking position, in which the pawl releases the rotary ratchet to release the catch eye, the pawl having a radial selector arm, the radial selector arm in the blocking position of the pawl interfering with the circular trajectory of the selector pivot for engagement of the selector pivot with the selector arm, the pawl having a radial control arm, the control arm angled against the radial selector arm and interfering in the unlocking position of the pawl with the circular trajectory of the selector pivot to block the movement of the selector pivot, the pawl comprising a selector sleeve with a selector arm and a control sleeve with a control arm, both the selector sleeve and the control sleeve being rotary-mounted side by side on the pawl pivot and linked together with a link torsion spring.
