Claims

[1] Unlocking device (1) for mechanically unlocking a locking unit, comprising a movable gear member (10) and a traction means (20) for introducing a tensile force (21) into the gear member (10) for the purpose of moving it, wherein the gear member (10) and the traction means (20) are integral components of a combination element (30) comprising the gear member (10) and the traction means (20). [2] Unlocking device according to claim 1, characterized by that at least in a transition region (31) of the combination element (30) between the transmission member (10) and the traction means (20), the transmission member (10) and the traction means (20) are made of the same material. [3] Unlocking device according to one of the preceding claims, characterized by that the transmission member (10) is a rotary element (13), wherein the traction means (20) merges into the rotary element (13) on a circumference thereof. [4] Unlocking device according to claim 3, characterized by that the rotation element (13) is rotationally fixedly coupled to a drive gear (40). [5] Unlocking device according to claim 4, characterized by that the drive gear (40) engages in a locking rack (60) which forms a locking pin (61) or is mechanically firmly connected to a locking pin (61). [6] Unlocking device according to one of claims 1 and 2, characterized by that the gear member (10) is a rack (14) into which an output gear (50) engages. [7] Unlocking device according to claim 6, characterized by that the output gear (50) is operatively connected to a locking rack (60) which forms a locking pin (61) or is mechanically firmly connected to a locking pin (61). [8] Method for producing an unlocking device (1) for mechanically unlocking a locking unit according to one of claims 1 to 7, in which a movable gear member (10) and a traction means (20) for introducing a tensile force (21) into the gear member (10) for the purpose of moving it are produced as integral components of a combination element (30) comprising the gear member (10) and the traction means (20). [9] Method for producing an unlocking device (1) for mechanically unlocking a locking unit according to claim 8, characterized in that the combination element (30) is produced in a primary forming process. [10] Motor vehicle, comprising an unlocking device (1) according to one of claims 1 to 7 and / or an unlocking device (1) manufactured according to the method for manufacturing an unlocking device (1).
