Abstract

The invention concerns a device for fixing a piece of equipment for a motor vehicle, in particular a heat exchanger (

20), on a structural element of the vehicle (

10) such as a front surface module. The invention is characterised in that the device comprises at least two shoes (

30) arranged on either side of the piece of equipment (

20), while the structural element (

10) comprises at least two substantially parallel internal edges (

11

a

, 11

b) defining an open part (

15) wherein is mounted the piece of equipment (

20). Each shoe is supported on one of the edges (

11

a

, 11

b) and on an external top surface (

24) of the piece of equipment and made in a deformable material such that the piece of equipment (

20) is force-mounted between the shoes (

30).

Claims

1. A device for fixing motor-vehicle equipment into a structural element of the vehicle including an open part in which the equipment is mounted, comprising at least two shoes made from a deformable material and arranged on either side of the equipment, the structural element having at least two substantially parallel and horizontal inner rims delimiting the open part, further having at least two lateral abutments projecting from the rims, and wherein each shoe bears on one of the rims, and on an outer prominent surface of the equipment such that when the equipment is mounted by force between the shoes, the shoes are positioned completely flush against the rim and the outer prominent surface for immobilization of the equipment, wherein the shoes are further in contact with the lateral abutments and positioned completely flush with the lateral abutments in order to avoid the shoes sliding in a direction parallel to the rims, wherein the parallel inner rims and the lateral abutments are integral, wherein the shoes exhibit a substantially “U” shape having two legs that are in contact with the equipment so as to hold it substantially fixed in a plane passing through the two rims.

2. A device according to claim 1, wherein at least one of the rims carries a lateral projection for at least one of the shoes, projecting in a plane substantially perpendicular to the surface of the rim, in such a way that the equipment is mounted by pivoting substantially about a ridge formed by the intersection of the lateral projection and of the rim.

3. A device according to claim 2, wherein the structural element includes a housing for at least one of the shoes, comprising side walls projecting from a rim in order substantially to immobilize the shoe with respect to a direction substantially parallel to the rims.

4. A device according to claim 1, wherein the structural element includes a housing for at least one of the shoes, comprising side walls projecting from a rim in order substantially to immobilize the shoe with respect to a direction substantially parallel to the rims.

5. A device according to claim 1, comprising means for lateral clipping of the equipment onto at least one vertical lateral rim which the structural element includes, adjacent to the two horizontal inner rims, wherein the lateral clipping means includes a protuberance disposed on the equipment and a matching housing disposed on the vertical rim such that only one matching housing engages with the protuberance.

6. A device according to claim 5, wherein the protuberance further includes an inclined plane projecting from an outer side wall, and suitable for interacting with a substantially matching housing which the lateral rim of the structural element includes in order to form the clipping means.

7. A device according to claim 6, wherein the equipment includes a heat exchanger equipped with a bank of tubes joined together at each of their opposite ends by a manifold plate closed by a fluid chamber intended for thermal exchange.

8. A device according to claim 7, wherein the inclined plane is configured over a lateral part of at least one of the fluid chambers.

9. A device according to claim 8, wherein the shoes bearing on one of the inner rims are substantial identical.

10. A device according to claim 9, comprising four shoes, each mounted straddling one extremity of a manifold plate.

11. A device according to claim 1, wherein the shoes are produced from a material having a coefficient of friction substantially equal to that of rubber.

12. A device according to claim 1, wherein the structural element includes a front-face module-comprising two opposing frames having apertures for housing lamps of the vehicle.
