ABSTRACT:
A drive arrangement for a security system has at least one actuating member which is supported so as to be movable out of an open position into a closing position, and vice versa, and serves to close and/or open locks, locking bolt mechanisms or catch mechanisms. Two reversible electric motors drive the actuating member by way of a geared connection which transforms rotational drive movements into translatory drive movements the geared connection is in the form of a differential gear unit having a driven member which is associated with the actuating member and having drive members which are associated with the electric motors. Each of the motors is in a geared connection with the drive members and forms an autonomously self-locking drive path which is supported by a bridge relative to forces emanating from the actuating member for moving the actuating member out of the open position into the closing position, and vice versa, individually or jointly or alternately.
