Abstract

A continuously blockable adjustment device for fixing two structural elements moveable in relation to one another, in particular a body of the motor vehicle and a door or flap of the motor vehicle moveable in relation to the body of the motor vehicle, includes a piston/cylinder unit with a cylinder, a piston displaceable axially in the cylinder, and a piston rod led out of the cylinder. The piston/cylinder unit has a piston-rod-side attachment element for connection to a first of the structural elements and a cylinder-side attachment element for connection to the second of the structural elements. A bracket at least partially engaging over the piston/cylinder unit axially is provided. The bracket 12 is fastenable in a first bracket end region to one of the two structural elements and, in a second bracket end region facing away from the first bracket end region, is tied to the piston-rod-side attachment element or the cylinder-side attachment element of the piston/cylinder unit.

Claims

1. A continuously blockable adjustment device for fixing two structural elements moveable in relation to one another, the two structural elements comprising a body of the motor vehicle and a door or flap of a motor vehicle moveable in relation to the body of the motor vehicle, said adjustment device comprising:

a piston/cylinder unit having a cylinder, a piston displaceable axially in the cylinder and a piston rod led out of the cylinder, the piston/cylinder unit having a piston-rod-side attachment element for connection to a first of the two structural elements and a cylinder-side attachment element for connection to the second of the two structural elements; and

a bracket at least partially engaging over the piston/cylinder unit axially, the bracket having a first bracket end region arranged and dimensioned to be connectable to one of the two structural elements and a second bracket end region facing away from the first bracket end region, the second bracket end region tied to one of the piston-rod-side attachment element or the cylinder-side attachment element of the piston/cylinder unit.

2. The adjustment device of claim 1, wherein the bracket comprises a rigid hollow body at least partially surrounding the piston/cylinder unit.

3. The adjustment device of claim 2, the hollow body is designed as a pot having an open top and closed bottom, wherein the second bracket end region is arranged at the bottom of the pot.

4. The adjustment device of claim 2, the hollow body (16) has a conical widening from the second bracket end region towards the first bracket end region.

5. The adjustment device of claim 1, wherein the bracket is plastic.

6. The adjustment device of claim 1, further comprising a connection device for a screw fastening of the bracket arranged in the first bracket end region.

7. The adjustment device of claim 1, further comprising an attachment element of the piston/cylinder unit which ties the bracket to the one of the piston-rod-side attachment element or the cylinder-side attachment element, the attachment element having a spherical element.

8. The adjustment device of claim 7, wherein the second bracket end region defines a recess in the form of a spherical cap supporting the spherical element.

9. The adjustment device of claim 8, further comprising a cover arranged on the second bracket end region and covering the spherical element.

10. The adjustment device of claim 9, wherein the cover has a recess in the form of a spherical cap supporting the spherical element.

11. The adjustment device of claim 7, wherein the attachment element includes an axially oriented threaded bolt threadably engaged with the spherical element.

12. The adjustment device of claim 7, wherein the attachment element has a joint socket, the spherical element being arranged in the joint socket.

13. The adjustment device of claim 12, wherein the joint socket has a bearing bush for mounting the spherical element.

14. The adjustment device of claim 12, further comprising a clip component fastening the spherical element in the joint socket.

15. The adjustment device of claim 11, wherein the threaded bolt passes centrally through the second bracket end region.

16. The adjustment device of claim 12, wherein the joint socket passes centrally through the second bracket end region.

17. The adjustment device of claim 1, wherein the first bracket end region is arranged and dimensioned to be fastened to an end face of a door of a motor vehicle, the second bracket end region is tied to the cylinder-side attachment element of the piston/cylinder unit, and the piston-rod-side attachment element of the piston/cylinder unit is arranged and dimensioned to be connected to the body of the motor vehicle, the piston rod passing through the end face of the door.
