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 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 invention relates to an assembly for securing a fastening element to a first component, wherein the first component has a passage opening for a shaft of the fastening element, said assembly comprising a securing element, which reaches around the shaft of the fastening element, wherein a head part of the fastening element and the securing element are arranged on opposite sides of the first component and the shaft of the fastening element engages in a receptacle of a second component for the frictional and/or interlocking connection of the two components. According to the invention, the securing element is pre-fastened to the second component before a first connection of the first component to the second component and is separated from the second component and reaches around the shaft of the fastening element after a first release of the connection between the first component and the second component.

Assembly and method for securing a fastening element

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

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
