According to the invention, the lock cylinder nut (3) has a connected eccentric element (6). Said eccentric element (6) engages in an eccentric mounting (7) of positioning element (8) in order to displace it. ## Claims ### Claim 1 A motor vehicle door lock having a lock housing, also with a lock cylinder nut supported in the lock housing, and having at least one locking element that can be acted upon by the lock cylinder nut via a positioning element, wherein the lock cylinder nut has a connected eccentric element that engages in an eccentric mounting of the positioning element in order to displace the positioning element, wherein the lock cylinder nut is rotatable about an axis of rotation, and the eccentric element has an eccentric shape whereby the eccentric element has eccentric rotational movement relative to the axis of rotation, wherein the eccentric element moves to a neutral position of during movement of the positioning element. ### Claim 2 (depends on 1) The motor vehicle door lock according to claim 1, wherein the eccentric element is conformed on the lock cylinder nut. ### Claim 3 (depends on 1) The motor vehicle door lock according to claim 1, wherein the eccentric element is a cam. ### Claim 4 (depends on 1) The motor vehicle door lock according to claim 1, wherein the positioning element is a linearly movable lock slider. ### Claim 5 (depends on 1) The motor vehicle door lock according to claim 1, wherein the positioning element has the eccentric mounting at one end thereof and an actuating pin at the other end. ### Claim 6 (depends on 5) The motor vehicle door lock according to claim 5, wherein the positioning element and the actuating pin thereof engages in a pin receiving hole of the locking element. ### Claim 7 (depends on 6) The motor vehicle door lock according to claim 6, wherein the pin receiving hole has a radial offset relative to an axis of rotation of the locking element in the locking element. ### Claim 8 (depends on 1) The motor vehicle door lock according to claim 1, wherein the positioning element clasps below the locking element. ### Claim 9 (depends on 1) The motor vehicle door lock according to claim 1, wherein the eccentric mounting has a U-shaped cross section. ### Claim 10 A motor vehicle door lock having a lock housing, also with a lock cylinder nut supported in the lock housing, and having at least one locking element that can be acted upon by the lock cylinder nut via a positioning element, wherein the lock cylinder nut has a connected eccentric element that engages in an eccentric mounting of the positioning element in order to displace the positioning element, wherein the lock cylinder nut is rotatable about an axis of rotation, and the eccentric element has an eccentric shape whereby the eccentric element has eccentric rotational movement relative to the axis of rotation, wherein the eccentric mounting has a U-shaped cross section. ### Claim 11 (depends on 10) The motor vehicle door lock according to claim 10, wherein the eccentric element is conformed on the lock cylinder nut. ### Claim 12 (depends on 10) The motor vehicle door lock according to claim 10, wherein the eccentric element is a cam. ### Claim 13 (depends on 10) The motor vehicle door lock according to claim 10, wherein the positioning element is a linearly movable lock slider. ### Claim 14 (depends on 10) The motor vehicle door lock according to claim 10, wherein the positioning element has the eccentric mounting at one end thereof and an actuating pin at the other end. ### Claim 15 A motor vehicle door lock having a lock housing, also with a lock cylinder nut supported in the lock housing, and having at least one locking element that can be acted upon by the lock cylinder nut via a positioning element, wherein the lock cylinder nut has a connected eccentric element that engages in an eccentric mounting of the positioning element in order to displace the positioning element, wherein the lock cylinder nut is rotatable about an axis of rotation, and the eccentric element has an eccentric shape whereby the eccentric element has eccentric rotational movement relative to the axis of rotation, wherein the positioning element has the eccentric mounting at one end thereof and an actuating pin at the other end. ### Claim 16 (depends on 15) The motor vehicle door lock according to claim 15, wherein the positioning element and the actuating pin thereof engages in a pin receiving hole of the locking element. ### Claim 17 (depends on 16) The motor vehicle door lock according to claim 16, wherein the pin receiving hole has a radial offset relative to an axis of rotation of the locking element in the locking element.
