An adjusting element formed in one piece and made of metal for compensating a tolerance in the distance between a first and a second component is described. The adjusting element comprises: a hollow-cylindrical body having a radially outwardly extending flange adjacent to a first axial end and an outer thread of a first thread direction at a radial outer side, a drive feature so that the adjusting element is rotatable by a tool, a receiving portion at the radial inner side of the hollow-cylindrical body, in which a dragging element is to be received, wherein the receiving portion comprises at least one radially inwardly extending protrusion, in particular a plurality of radially inwardly extending protrusions, at a radial inner side of the hollow-cylindrical body adapted to a form-fit connection with the dragging element and at least one shoulder extending circumferentially at the radial inner side and providing an axial limitation.

Adjusting element, first component with adjusting element, connection structure comprising the first component, manufacturing method of the adjusting element and connection method

A tolerance compensation arrangement for fastening first and second components with compensation of tolerances between the components. The arrangement comprises a base element having a first element with a first inner thread, a second element with a second inner thread, a supporting element arranged in between, and an adjustment unit with a threaded sleeve with an outer thread and a dragging unit at least partially arranged in the sleeve. The outer thread forms a first thread pairing of a first thread direction with the first inner thread. A fastening screw, can be screwed into the second inner thread via a second thread pairing of a second thread direction opposite to the first thread direction. The fastening screw can be connected to the adjustment unit via the dragging unit so that, during the rotation of the fastening screw, the adjustment unit co-rotates and is moved into abutment with the first component.

Tolerance compensation assembly

To fasten a first component to a second component, a fastening clip has an integral, elongated structure with a first and a second fastening end. The first fastening end comprises an at least one-armed independent latching structure. The second fastening end is formed by a resilient clamp. The first and second latching structure act on an intermediate support structure. To connect the two components, the latching structure is latched in a component opening in a first component, and the second component is fastened between the support structure and a spring loop of the resilient clamp with the assistance of a cutout or a slot that is open on one side.

Fastening clip

An elastically deformable coupling part for a plug-in connection for connecting a first component and a second component, has an inner connection portion, in which a head of a pin-like element of the second component can be accommodated by a detent or snap-in connection. In addition, the coupling part has an outer fastening portion, which can be connected to a keyhole of the first component by a bayonet closure. The fastening portion comprises at least one radial contact surface. At least one first radial projection, which forms a bayonet gap for a rotational accommodation of the first component, is arranged at an axial distance from the radial contact surface. At least one second radial projection, which forms a locking gap for the first component between the second projection and the radial contact surface by a movability directed inward, is arranged at an axial distance from the radial contact surface.

Plug-in coupling having an elastically deformable coupling part and installation method therefor

A joining assembly for joining a pair of structural members, comprises a bolt having a thread and a nut-like blind rivet adapted to be inserted into mounting holes of the structural members and to be threadingly engaged to each other. One of the mounting holes is made of resiliently deformable material and comprises a base member including a bore for receiving the thread of the bolt and having an outside provided with a plurality of threads which are similar in number to the corners of the polygonal mounting hole, such that when the bolt is threadingly engaged into the bore of the blind rivet the base member is folded whereby the threads have parts of their flanks pressed against one of the structural members.
