  • Publication number: 20090309374
    Abstract: The invention relates to an outside door grip, in particular for vehicles. The outside door grip exhibits a manually actuated handle, which engages a lock disposed in the door upon actuation. In addition, a pivotable blocking member serving as a mass blockage is furnished, which blocking member is disposed generally in its ineffective disengagement position, wherein the handle remains actuatable, which blocking member moves into an effective blocking position based on the inertia of its mass in case of a crash and thereby blocks the handle. Furthermore means are furnished which take care that the blocking member remains at least so long in its blocking position in case of a crash, until oscillations caused by the crash and acting on the outside door grip and/or the handle, have decayed so far that an effective actuation of the handle by the oscillations is not any longer possible.

  • Publication number: 20090223264
    Abstract: A locking cylinder comprises a two-part housing, comprising an upper part and a lower part. A cylinder core (20) is received in said housing and can be actuated by turning a key. The housing of the locking cylinder is fastened to the body of a vehicle (34) by fastening means (30). The aim of the invention is to reduce the space required by and simplify handling of the locking cylinder. For this purpose, the fastening means (30) used to fasten (34) the housing of the locking cylinder on the body is also used as a connecting means for fastening the housing upper part on the housing lower part.

  • Patent number: 7302819
    Abstract: A device for actuating a lock on a vehicle door has a support mounted on a vehicle door. A lock cylinder mount, or a decoy, is mounted on the support. A screw secures the mount when mounted on the support. The mount has a shoulder engaging a counter shoulder of the support at least partially in the mounting position of the mount. The screw has an actuating end for moving the screw into a release position and a locking position. In the release position, the mount is removable from and mountable on the support. In the locking position, the mount is secured. The mount has a threaded receptacle for the screw so that the screw is part of the mount. The support has a screw support surface against which the actuating end of the screw rests in the locking position of the screw for securing the mount.

  • Publication number: 20040129040
    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).
