Description

DEVICE FOR ADJUSTING THE POSITION OF A SLIDING SUNROOF OF A MOTOR VEHICLE
The present invention relates to a device for adjusting the height of the position of a sliding sunroof relative to the fixed roof of a motor vehicle, disposed between the reinforcement of the sliding sunroof and the guide shoe of the sliding roof.

Such adjustment devices are known in the art such as, for example, that described and represented in the French patent application published under the number 2 527 995.

The known devices have the drawback of being complex, difficult to access after installing the sliding sunroof on the vehicle.

In order to remedy these drawbacks, the present invention provides an adjustment device characterized in that it comprises a fixed guide ferrule attached to the reinforcement, an adjustment ring threaded on the guide ferrule, mounted to rotate on the latter and whose external threaded wall is mounted screwed into a threaded bore of a connecting element connected to the guide shoe and immobilized in rotation relative to the reinforcement by a pin received in an opening of the reinforcement in which the pin is capable of moving vertically , and a screw for holding and immobilizing the adjustment ring in rotation, the head of which bears on the adjustment ring and the threaded rod of which is screwed into an internal coaxial bore of the guide ring.

The invention will now be described with reference to the accompanying drawing in which the single figure represents a partial section of a motor vehicle roof fitted with a sliding sunroof passing through a guide shoe of the sunroof.

A fixed vehicle roof 10 has been shown in an opening of which a sliding sunroof 12 is mounted.

The sunroof 12 is provided with a peripheral reinforcement element 14.

The sunroof 12 can, for example, be made of transparent acrylic glass and fixed by gluing to the reinforcement 14.

A seal 16 of the roof edge slot, attached to the sliding roof 12 seals by cooperating with a folded edge 18 of the fixed roof 10.

A guide frame 20 of the sliding roof 12 is fixed on the fixed roof 10 and comprises two guide slides 22 of the guide and / or sliding skids of the sunroof 12
The guide profile 22 constitutes a guide path for the guide shoes. The part 20 is extended at its lower part by a lower wing 24 which receives by plugging in a profile 26 for clamping and maintaining a covering of the fixed roof 10.

The lower wing 24 is folded in such a way that it provides, with the lower part of the guide frame 22, a sliding path 28 of the internal covering 30 of the sliding sunroof 10.

The reinforcing element 14 is finally provided with a covering strip 53 which covers inwards in the direction of the cut-out of the fixed roof the functional parts arranged on the guide frame 20.

According to the invention, a device 32 for height adjustment of the position of the sliding sunroof 10 relative to the fixed roof 10 is disposed between the sliding roof reinforcement 14 and the guide shoe 34 of the sliding roof 12 received in the frame. guide 22, elements 14, 34 of which it also provides the mechanical connection.

The device 32 includes a fixed cylindrical guide ring 36 attached to the reinforcement 14 and extending vertically downwards through an opening in the reinforcement 14.

The device 32 also includes an adjustment ring 38 threaded onto the guide ring 36.

The adjustment ring 38 is mounted to rotate freely on the guide ring 36 and is supported by its upper face on the reinforcement 14.

your ring 38 is held in abutment on the reinforcement 14 by means of a screw 40, the head 42 of which bears on the underside of the adjustment ring 38 and the threaded rod 44 of which is screwed into a threaded blind bore 46 of the guide ring 36, coaxial with the axis common to the ring 36 and the ring 38.

The external cylindrical wall of the adjustment ring 38 is provided with a thread 48. Thanks to this threaded wall 48, the adjustment ring constitutes a height adjustment screw which is mounted screwed in a threaded bore 48 of a connecting element 50.

The connecting element 50 is connected to the guide shoe 34 by a pin 52 passing through a vertical wing 54 of the connecting element.

In order to allow height adjustment by means of the adjustment ring 38, the connecting element 50 is capable of moving vertically relative to the reinforcement 14 but is immobilized in rotation relative to the latter around the axis of rotation common to the adjusting device 32.

The immobilization in rotation is obtained by means of a guide pin 56 received in an opening 58 of the reinforcement 14 in which the pin 56 is capable of sliding vertically.

The adjustment and connection system 32 naturally equips each guide and / or connection pad of the sliding sunroof 12.

te adjustment of the height of the sunroof 12 is carried out, after having carried out the positioning thereof on the vehicle, by acting on each of the adjustment devices 32 fitted to the guide pads. Each adjustment is carried out, the screw 40 immobilizing the adjustment being loosened, by rotation using
the hexagon head of a suitable tool from / the adjusting ring 38. , which has the effect of causing a vertical displacement of the connecting element 50 relative to the reinforcement 14. When the adjusted position is reached, it only remains to tighten the screw 40 which then immobilizes in rotation and in axial translation. adjustment ring 38 relative to the guide ring 36.

Adjustment and locking can be carried out by a single tool (not shown) which cooperates with the external profile of the adjustment ring 38 and which also incorporates a body of a screwdriver or coaxial key which makes it possible to tighten or loosen the screw 40 .
