Abstract

A fastening apparatus is provided for fastening a component to a bolt of a carrier component. The fastening apparatus includes a housing device having a receiving space for receiving a bolt in an axial direction and a fastening clip arranged in the receiving space of the housing device, wherein the fastening clip includes at least two, preferably spring-like latching arms, at whose free ends preferably linear latching edges are formed so as to hold a bolt, wherein the latching edges of the latching arms are inclined relative to the axial direction.

First claim

1 . A fastening apparatus for fastening a component to a bolt of a carrier component, comprising:
a housing device having a receiving space for receiving a bolt in an axial direction, and a fastening clip arranged in the receiving space of the housing device, wherein the fastening clip comprises at least two latching arms, at whose free ends latching edges are formed so as to hold a bolt, wherein the latching edges of the latching arms are inclined relative to the axial direction.

2 . The fastening apparatus according to claim 1 ,
wherein the latching edges of the latching arms are linearly formed and inclined orthogonally to the axial direction relative to an X/Y plane in two different directions, respectively, such that the latching edges of the latching arms have a predetermined slope that is radially circumferential or tangential, to a bolt to be received and thus to an axial axis of the receiving space.

3 . The fastening apparatus according to claim 1 ,
wherein due to the slope of the latching edges relative to the axial direction and/or the X/Y plane, the latching arms are configured such that the fastening apparatus can be assembled on a bolt by a movement in the axial direction and can be disassembled by a rotational movement about a longitudinal axis of a bolt extending in the axial direction.

4 . The fastening apparatus according to claim 1 ,
wherein the housing device comprises a base wall having a bolt passage opening for introducing a bolt into the receiving space, two diametrically opposed side wall portions, and a top wall, wherein the base wall is connected to the top wall via the two side wall portions, and wherein portions of the side wall portions facing the receiving space, which are referred to as stop portions, are configured in the region of the base wall so as to be conically tapering from the side walls in the direction of the base wall, wherein free ends of the fastening clip, onto which the latching arms are formed, comprise conically tapering pressure portions in the region of the stop portions.

5 . The fastening apparatus according to claim 4 ,
wherein in a final assembly position, in which the fastening apparatus is caught on a bolt, the pressure portions are arranged so as to be spaced apart from the respective stop portions, and wherein in a stressed final assembly position, in which the fastening apparatus is tension-stressed, the pressure portions abut the stop portions, so that the pressure portions of the fastening clip, due to the conically tapering design of the stop portions and the pressure portions, act on the latching edges of the latching arms with a pressure force acting in the radial direction inwards in the direction of the receiving space and thus in the direction of a bolt.

6 . The fastening apparatus according to claim 4 ,
wherein at the portions of the side wall portions facing the receiving space and arranged adjacent to the stop portions, anti-rotation portions are formed, having anti-rotation elements facing in the direction of the receiving space, wherein the fastening clip comprises anti-rotation recesses in this region, in which the anti-rotation portions are received, such that the fastening clip is received in the receiving space of the housing device in a rotation-proof manner.

7 . The fastening apparatus according to claim 1 ,
wherein insertion elements that conically taper in the direction of the receiving space are formed on the base wall in order to subject the fastening clip to a bias, so that it can be arranged in the receiving space in an assembly position.

8 . The fastening apparatus according to claim 1 ,
wherein a bolt receptacle extending in the axial direction and configured in portions so as to be tubular is arranged in the receiving space for guiding and positioning a bolt to be received, wherein the bolt receptacle connects the top wall and the base wall.

9 . A fastening system having a fastening apparatus according to claim 1 and a threaded bolt or a bolt having a planar sheath wall.

10 . A method for assembling a fastening apparatus, comprising the following steps:
moving a fastening clip orthogonally to an axial direction in the direction of a receiving space of a housing device, compressing free ends of the fastening clip by means of corresponding, conically tapering insertion elements and thereby subjecting the free legs of the fastening clip to a bias, further sliding of the fastening clip in a direction orthogonal to the axial direction, arranging anti-rotation portions of the housing device in corresponding anti-rotation recesses of the fastening clip and thereby arranging the fastening clip in the receiving space of the housing device in a rotation-proof manner.
