The adjustment element comprises a bush, a dragging element, a contact disc, and a securing sleeve. The bush has a bore, an outer thread with a first direction, and a step. The dragging element comprises at least one spring arm protruding radially inwards, wherein a first axial end of the dragging element is arranged on the step in the threaded bush. The contact disc is arranged adjacently to the first axial end of the threaded bush and has a through-opening. The securing sleeve likewise has a through-opening and is arranged at least partly in the bore of the threaded bush with a press-fit connection in order to securely connect the contact disc, the threaded bush, and the dragging element together. ## Claims ### Claim 1 A multipart adjustment element for a tolerance compensation arrangement for the automatic compensation of tolerances in the spacing between a first and a second component, including: a. a threaded bush having a passage bore, an outer thread of a first thread direction as well as a step that is formed inside of the threaded bush so that a first inner diameter adjacent to the first axial end of the threaded bush is larger than a second inner diameter adjacent to the second axial end of the threaded bush, b. a dragging element with at least one radially inwardly protruding spring arm wherein the dragging element is arranged with a first axial end on the step which is formed in the threaded bush, as well as c. an abutment disc adjacent to the first axial end of the threaded bush which includes a passage opening, and d. a securing sleeve with passage opening which is arranged at least partially in a press-fit in the bore of the threaded bush in order to tightly connect the abutment disc, the threaded bush and the dragging element with each other. ### Claim 2 (depends on 1) The multipart adjustment element according to claim 1, in which the dragging element has a continuous slot extending along the longitudinal axis. ### Claim 3 (depends on 2) The multipart adjustment element according to claim 2, in which the at least one spring arm of the dragging element is attached on one side, only so that the at least one spring arm has a free end. ### Claim 4 (depends on 2) The multipart adjustment element according to claim 2, in which the dragging element has a plurality of projections extending in the longitudinal direction at its first and at its second axial end, the projections forming a first anti-rotation protection in connection with the step and a second anti-rotation protection in connection with the securing sleeve. ### Claim 5 (depends on 2) The multipart adjustment element according to claim 2, in which the dragging element comprises a plurality of axially compressible webs. ### Claim 6 (depends on 2) The multipart adjustment element according to claim 2, in which the passage opening of the abutment disc has a chamfer at the side which faces away from the threaded bush. ### Claim 7 (depends on 2) The multipart adjustment element according to claim 2, in which the securing sleeve has a flange at a first axial end and a knurling adjacent to a second axial end at a radial outside, so that the securing sleeve engages adjacent to the first axial end, in particular with the flange, with the abutment disc, at the second axial end with a second axial end of the dragging element and at the radial outside at least partly with the radial inside of the threaded bush. ### Claim 8 (depends on 7) The multipart adjustment element according to claim 7, in which the knurling has a conical form so that the knurling engages with the inside of the threaded bush and forms a fourth anti-rotation protection. ### Claim 9 (depends on 1) The multipart adjustment element according to claim 1, in which the at least one spring arm of the dragging element is attached on one side, only so that the at least one spring arm has a free end. ### Claim 10 (depends on 1) The multipart adjustment element according to claim 1, in which the dragging element has a plurality of projections extending in the longitudinal direction at its first and at its second axial end, the projections forming a first anti-rotation protection in connection with the step and a second anti-rotation protection in connection with the securing sleeve. ### Claim 11 (depends on 1) The multipart adjustment element according to claim 1, in which the dragging element comprises a plurality of axially compressible webs. ### Claim 12 (depends on 1) The multipart adjustment element according to claim 1, in which the passage opening of the abutment disc has a chamfer at the side which faces away from the threaded bush. ### Claim 13 (depends on 1) The multipart adjustment element according to claim 1, in which the securing sleeve has a flange at a first axial end and a knurling adjacent to a second axial end at a radial outside, so that the securing sleeve engages adjacent to the first axial end, in particular with the flange, with the abutment disc, at the second axial end with a second axial end of the dragging element and at the radial outside at least partly with the radial inside of the threaded bush. ### Claim 14 (depends on 13) The multipart adjustment element according to claim 13, in which the knurling has a conical form so that the knurling engages with the inside of the threaded bush and forms a fourth anti-rotation protection. ### Claim 15 (depends on 1) The multipart adjustment element according to claim 1, in which the securing sleeve includes an outer chamfer at a second axial end. ### Claim 16 (depends on 1) The multipart adjustment element according to claim 1, wherein the threaded bush, the dragging element, the abutment disc and the securing sleeve are made of steel or stainless steel. ### Claim 17 (depends on 1) A tolerance compensation arrangement with a multipart adjustment element according to claim 1 and a basic element, wherein the basic element is fastened at the first component and includes a first inner thread of a first thread direction, which is in engagement with the outer thread of the threaded bush of the multipart adjustment element, and the basic element includes a second inner thread with a second thread direction, which is opposite to the first thread direction, wherein in use, the second inner thread interacts with an outer thread of a fastening screw, so that the fastening screw, when being inserted into the multipart adjustment element and being rotated, co-rotates the multipart adjustment element via the dragging element through friction connection, thereby screwing it out of the basic element contrary to the insertion direction for the purpose of tolerance compensation and, when the adjustment element has abutted the second component, is screwable with the second inner thread of the second thread direction for the purpose of tensioning both components. ### Claim 18 (depends on 17) The tolerance compensation arrangement according to claim 17 in which the basic element is a blind rivet nut. ### Claim 19 (depends on 17) The tolerance compensation arrangement according to claim 17, furthermore including a fastening screw. ### Claim 20 (depends on 19) A connection between a first and a second component by means of the tolerance compensation arrangement according to claim 19.
