Abstract: In said devices the operation of the handle serves to open the door when the lock is in the unlocked position. The handle operation is achieved by means of an operating lever (30) and the rotation of the lock cylinder (60) is transferred to a carrier (45). According to the invention, the construction may be simplified and rendered flexible, whereby a control member (50) is used, which transmits the movement of the carrier (45) to the operating lever (30) of the handle. The operating lever (30) has an adjustable bearing position (31, 11 or 32, 12), which is determined in relation to the rotational position of the lock cylinder (60) by the control member (50). The transfer ratios (34.1 to 33.1 or 34.2 to 33.2) on the operating lever (30) are thus altered relative to a connector (40) leading to the lock. Although an identical operation of the handle occurs, differing working strokes (36) occur at the connector (40).

Abstract: An opening system for a movable passenger motor vehicle body part, such as a door, has lock which is arranged on an inner shell of the vehicle body part and can be operated by an outside handle arrangement, which is fixed on an outer shell of the vehicle body part. A deformation-resistant supporting arrangement is provided at the level of the outer handle arrangement on a side of the inner shell of the vehicle body part facing the outside handle arrangement, which supporting arrangement projects toward the outside handle arrangement.

Abstract: An interior securing device for a lock of a movable vehicle body part of a motor vehicle includes a Bowden cable provided as a transmitting device which is rigidly connected with a securing knob and is linked to an adjusting element. The Bowden cable is surrounded along its length by a flexible guiding sleeve. Near the securing knob, the guiding sleeve is held fixed to the vehicle body part. Near the adjusting element, the guiding sleeve is held fixed to the lock. The securing device is particularly suitable for use with rear side doors of passenger cars.
