The drive arrangement comprises a motor and a spindle drive connected to the motor, the spindle drive containing a spindle and a spindle nut mounted thereon. The spindle is coaxially driven by a driven shaft of the motor. The spindle nut acts on the actuating element in order to rotate it by at least one interposed coupling element. The spindle nut and the coupling element form a single unit. ## Claims ### Claim 1 A drive arrangement for motorized adjustment of an actuating element, rotatably mounted inside a motor vehicle door latch housing, the drive arrangement comprising: a motor, a spindle drive connected to the motor, said drive comprising a spindle and a spindle nut mounted thereon, with the spindle being coaxially driven by a driven shaft of the motor and in which the spindle nut acts on the actuating element, and at least one coupling element interposed between the actuating element and the spindle nut for rotating the actuating element, wherein the spindle nut and the coupling element are integrally formed as a single-piece part unit. ### Claim 2 (depends on 1) The drive arrangement according to claim 1, wherein the coupling element extends from an underside of the spindle nut in a direction that is perpendicular to an axial drive direction of the spindle drive. ### Claim 3 (depends on 2) The drive arrangement according to claim 2, wherein the coupling element contains a pin at an end thereof that engages in a seat of the actuating element in order to rotate the actuating element. ### Claim 4 (depends on 3) The drive arrangement according to claim 3, wherein a face of the coupling element is L-shaped. ### Claim 5 (depends on 4) The drive arrangement according to claim 4, wherein a first leg of the face of the coupling element is connected to the spindle nut. ### Claim 6 (depends on 5) The drive arrangement according to claim 5, wherein a second leg of the face supports the pin. ### Claim 7 (depends on 6) The drive arrangement according to claim 6, wherein the pin protrudes from a side of the second leg that opposes a side at which the first leg is connected to the second leg. ### Claim 8 (depends on 6) The drive arrangement according to claim 6, wherein the pin is arranged at an end of the second leg opposite an end at which the first leg is connected to the second leg. ### Claim 9 (depends on 6) The drive arrangement according to claim 6, wherein the spindle nut contains a connection area for the coupling element in a longitudinal extension thereof and a threaded section for engaging into the spindle. ### Claim 10 (depends on 9) The drive arrangement according to claim 9, wherein the spindle nut contains at least one guide. ### Claim 11 (depends on 10) The drive arrangement according to claim 10, wherein the guide interacts with at least one counter guide in the motor vehicle door latch housing. ### Claim 12 (depends on 1) The drive arrangement according to claim 1, wherein the coupling element contains a pin at an end thereof that engages in a seat of the actuating element in order to rotate the actuating element. ### Claim 13 (depends on 12) The drive arrangement according to claim 12, wherein a face of the coupling element is L-shaped. ### Claim 14 (depends on 13) The drive arrangement according to claim 13, wherein a leg of the face of the coupling element is connected to the spindle nut. ### Claim 15 (depends on 14) The drive arrangement according to claim 14, wherein a second leg of the face supports the pin. ### Claim 16 (depends on 1) The drive arrangement according to claim 1, wherein a face of the coupling element is L-shaped. ### Claim 17 (depends on 1) The drive arrangement according to claim 1, wherein the spindle nut contains a connection area for the coupling element in its-a longitudinal extension thereof and a threaded section for engaging into the spindle. ### Claim 18 (depends on 17) The drive arrangement according to claim 17, wherein the spindle nut contains at least one guide. ### Claim 19 (depends on 18) The drive arrangement according to claim 18, wherein the guide interacts with at least one counter guide in the motor vehicle door latch housing.
