Direct current motors` electrical control circuit for motor vehicle seat, has electromechanical relay to connect motors in parallel/series when relay is at rest/active, and actuator whose terminals are connected with that of motors

摘要

The circuit has an electromechanical relay (30) with contacts to electrically connect direct current motors (M1, M2) in parallel and series when the relay is at rest and active, respectively. An inductive unit of the relay is in series with a capacitor between a control terminal connectable to a supply potential (P) and the ground (M). An actuator (50) has terminals (53, 56) connected to the respective terminals (41, 43) of the motors. An independent claim is also included for a seat comprising an electric seat movement control system including an electrical control circuit.
