A door handle system for actuation of a moveable part of a vehicle with a carrier arrangeable at the inner side of the moveable part, a door handle arrangeable at the outer side of the moveable part by the carrier. The door handle comprises two ends over a longitudinal extension at which connecting means are provided for the arrangement at the carrier respectively, a fasteningelement which serves for the arrangement of the door handle by connecting means at the carrier. The fasteningelement comprises at least one release position and one fixing position and an adjustment element for the adjustment of the fastening element The fastening element retains the door handle at the carrier in a fixing position. The fastening element is configured from two parts, wherein the two parts of the fastening element are coupled to one another.

The invention relates to a motor vehicle door lock which is equipped with a locking mechanism (1, 2) consisting of essentially a rotary latch (1) and a pawl (2), in addition to an actuating lever chain (4) and a locking unit (5, 6). Said motor vehicle door lock also comprises a security device (8, 9, 10) which can optionally set the actuating lever chain (4) and/or the locking unit (5, 6) in a non-functioning state/functioning state. According to the invention, said security device (8, 9, 10) is designed as a retrofitted module (8, 9, 10) which can be connected, according to requirements, to a base module (1-6 and 11), said module surrounding the largest part of the locking mechanism (1, 2), the actuating lever chain (4) and the locking unit (5, 6).

The present invention relates to a door handle system (10) for actuation of a moveable part (101) of a vehicle (100), particularly a door, or hatchback or such like with a carrier (11) which is arrangeable at the inner side (101.1) of the moveable part (101), a door handle (12) which is arrangeable at the outer side (101.2) of the moveable part (101) by the carrier (11) and the door handle (12) comprises two ends (12.2) over its longitudinal extension (18) at which connecting means (12.3) are provided for the arrangement at the carrier (11) respectively, a connecting element (15) which serves for the arrangement of the door handle (12) by at least one connecting means (12.3) at the carrier (11), wherein the connecting element (15) comprises at least one release position (I) and one fixing position (II) and an adjustment element (16) which serves for the adjustment of the fastening element (15) between the release position (I) and the fixing position (II), wherein the fastening element (15) retains the door handle (12) at the carrier (11) in its fixing position (II) by both connecting means (12.3), characterized in that the fastening element (15) is configured from two parts, wherein the two parts (30, 40) of the fastening element (15) are coupled to one another.
