A damping arrangement which is fastenable in an opening of a first component and by which a dampened connection of the first component with a second component is realizable, including, two identically constructed damping elements. Each damping element includes: a head portion with a first outer diameter, a shaft portion with a second outer diameter that is smaller than the first outer diameter and extends from a bottom side of the head portion, as well as a central first thru-opening, and only one sleeve with a central second thru-opening being arranged at least partly in the central first thru-opening of each damping element by means of a frictional and/or material connection. By means of the only one sleeve, the two identically constructed damping elements with bottom sides, facing each other, of the head portion with the first component arranged in between are fastenable to one another.

Damping arrangement, component with damping arrangement as well as corresponding component connection, a manufacturing method and a connecting method

An elastic connecting block with which, by receiving a connecting pin, at least two components can be connected together via a respective component opening. The connecting block, which is formed as a single piece, comprises a central bearing block with two mutually opposing bearing surfaces for the components to be connected. A locking flange, which can be engaged in a component opening, is provided on the first bearing surface. On the other bearing surface, a widening flange is provided, which can be expanded by a spherical head of the connecting pin such that the widening flange is held via an axial undercut in the second component opening of the second component.

Resilient connecting block, connecting pin therefor, and a connection between two components via the resilient connecting block

A female coupling clamp which is adapted to hold a coupling head of a male coupling element in an automatic or self-latching manner and to fasten itself in a component opening in an automatic latching manner. For this, the coupling clamp is equipped with at least three resiliently formed strip-type coupling arms which are connected to each other on one side. The respective provided fastening ends of the coupling arms comprise a radially outwardly open receiving groove for an edge of a component opening. A ball head is held in a receiving space with the aid of a neck portion which is similar in shape to an inverted truncated pyramid.

Coupling clamp

A thread element mode of plastic, a connection assembly consisting of a support part made of plastic into which the thread element made of plastic has been screwed by creating a counter-thread, a method for manufacturing the connection as well as a method for manufacturing the thread element. The thread element is characterized by an axial piece on which the circumferential windings of a thread turn are interrupted by at least two chip flutes. The resulting winding areas form a cutting web and an inhibition web, whereby the cutting web extends radially beyond the inhibition web.

Plastic thread element and connection assembly consisting of a plastic carrier part and a plastic thread part

A fastening arrangement with damping effect, consisting of two structurally identical fastening units each having a central first through opening. Each fastening unit comprises a mounting element and a damping element. The mounting element is disc-shaped with a central second through opening and an identical detent structure extends from a first side of each mounting element. The damping element is disc-shaped with a central third through opening and is arranged at last partially in the central second through opening of the mounting element. Due to this construction the two fastening units can be fastened to one another by means of the mutually facing first sides having the identical detent structure of the respective mounting elements with first component arranged between them.

Fastening arrangement with damping effect and component connection to the fastening arrangement

The present disclosure describes a spring connection element, by means of which at least two components can be connected to each other by means of a claw-fit in at least one component opening. The spring connection element is characterized by the following features: a spiral spring-like wire coil with a first and a second end, said coil comprising a plurality of axially spaced windings, a spiral collar which extends radially beyond a circumference of the wire coil and which is arranged at the first end of the wire coil, and a central traction element protruding radially into the wire coil, which is arranged at the second end of the wire coil, which does not extend axially beyond the wire coil, and by means of which the spring connection element can be pulled into a component opening substantially rotation-free.

The present disclosure is directed to a coupling element for the releasable connection of a first component to a second component. The coupling element has an annular basic element comprising a fastening structure at a radially outer side. Further, the basic element comprises a socket-like holding structure at a radially inner side. The socket-like holding structure comprises a centrally arranged supporting element as well as a plurality of holding webs. The holding webs comprise at least a first and a second web section. The first web section encloses with an axis of symmetry S of the coupling element an angle &#x221d; from a range of 45&#xb0;&#x2264;&#x221d;&#x2264;90&#xb0; and the first web section and the second web section are arranged in an obtuse angle with respect to each other.

Plug-in coupling from coupling element and ball stud

Coupling by means of which a first and a second component are connectable to each other, having the following features: a coupling bolt having a fastening end, a holding head and a supporting section arranged therebetween, in which the holding head and the supporting section are connected to each other by means of a web, which is tapered with respect to the holding head, and the fastening end is fastenable at the first component, a holder having a keyhole and an abutting portion, in which an edge of the keyhole encloses a non-planar surface, the coupling bolt is lockable in the keyhole in a form-fit manner by means of an inserting-pivoting-movement and the holder is fastenable at the second component by means of a fastening structure.

Coupling consisting of coupling bolt and holder as well as method for connecting a first and a second component by means of the coupling

The present invention provides an adjustment elementwith which a component can be fastened and can be positioned in space. The adjustment element has the following features: a banjo boltwith an external threadwith which the component holdercan be positioned in the axial direction of the banjo bolt, an inner elementwhich is arranged within the banjo boltand to which the banjo boltis rotatably fastened, and a washerwhich is held between the banjo boltand inner elementin a manner such that it can be laterally displaced in the axial direction of the inner elementsuch that the adjustment elementcan be laterally positioned and can be fixed with a fastening meansreaching through the washer
