A control (18) for a seat belt positioning device (10) includes a motor (12) for positioning a seat belt component (16). A locking tongue sensor (20) generates a locking tongue signal (S) depending on whether a locking tongue is inserted in a belt buckle (16). A trigger circuit (22) connected to the locking tongue sensor (20) generates a trigger signal (TR, TR1, TR2, VT, TM) in response to the locking tongue signal (S) A timer (32) or a motor load circuit (33) connected to the trigger circuit (22) generates a motor signal (M) having a predetermined period or depending on a motor load in response to the trigger signal (TR, TR1, TR2, VT, TM). A motor control circuit (34) connected to the timer (32) and the trigger circuit (22) turns the motor on and off in response to the motor signal (M). The direction of motion of the motor (12) is selected depending on the trigger signal (TR, TR1, TR2, VT, TM).
