Fastening device having a compensating rail for tolerance compensation
View Patent ↗A fastening device for fixing lines in the engine compartment of a motor vehicle, in particular lines for the air conditioner. Fastening recesses are provided in the engine compartment, on which the fastening device can be anchored. The fastening device has a clip base for this purpose. A clip head is used for fastening the fastening device to the line. At least one of the fastening clips is situated so it is longitudinally movable on the compensating rail, so that the fastening device can be adapted to the installation situation.
1. A fastening device for lines in an engine compartment of a motor vehicle, the fastening device comprising:
at least two fastening clips, one of the at least two fastening clips having a clip base for attachment in the engine compartment and at least one of the at least two fastening clips having a clip head for attachment to a line; and
a compensating rail on which one or more fastening clips of the at least two fastening clips is situated and longitudinally movable, the one or more fastening clips comprising a fully rotatable fastening clip having a ball head that is enclosed by an area of the compensating rail.
2. The fastening device according to claim 1 ,
wherein the area enclosing the ball head is formed from a first surface angled to a second surface with which the ball head is in contact,
wherein the first surface and the second surface are configured to exert a force on the ball head so that friction surfaces are formed between the ball head and the first surface and the second surface of the area.
3. The fastening device according to claim 2 , wherein the area enclosing the ball head is extended in one direction so that a trough is formed in which the one or more fastening clips is situated for longitudinal movement.
4. The fastening device according to claim 1 ,
wherein the clip base has a spreading element to situate in a fastening point that is implemented as an undercut fastening recess,
wherein the spreading element engages in the undercut fastening recess under pressure action on the clip base in the engine compartment.
5. The fastening device according to claim 1 , wherein the clip head is formed from an essentially U-shaped clamp having an enclosure area pointing inward on ends of the essentially U-shaped clamp so that the line engages in the essentially U-shaped clamp upon pressure action.
6. The fastening device according to claim 1 , wherein the compensating rail is flexible and bendable into a desired shape in the engine compartment.
7. The fastening device according to claim 1 , wherein the at least two fastening clips are situated for rotation on the compensating rail.
8. The fastening device according to claim 1 , wherein both of the at least two fastening clips are situated and longitudinally movable on the compensating rail.
9. The fastening device according to claim 1 , further comprising a plurality of clip heads situated on the compensating rail.
10. The fastening device according to claim 1 , wherein the compensating rail is bent over.
11. The fastening device according to claim 1 , wherein the at least two fastening clips are configured for an air-conditioning system.
