Abstract

A door handle arrangement may have a carrier element, a handle element, which is movably arranged on the carrier element between a non-use position and a use position, and an adjusting mechanism for adjusting the handle element relative to the carrier element. The adjusting mechanism may have at least one lever and a cam carrier having at least one main cam for the controlled movement of the handle element between the non-use position and the use position. The main cam may interact with a cam counter surface arranged on the lever and may have a variable curve shape.

First claim

The invention claimed is:

1. A door handle arrangement, comprising:
a carrier element,
a handle element which is movably arranged on the carrier element between a non-use position and a use position, and
an adjusting mechanism for adjusting the handle element relative to the carrier element,
wherein the adjusting mechanism comprises a lever mechanism having a first single-arm lever and a second single-arm lever and a cam carrier having at least one main cam in each arm for the controlled movement of the handle element between the non-use position and the use position, and
wherein each main cam interacts with a respective cam counter surface arranged on the first single-arm lever and the second single-arm lever and has a variable curve shape,
wherein each single-arm lever comprises a respective cam guide formed therein, and
wherein the adjusting mechanism comprises at least two axes;
where a first axis is a cam axis of the cam carrier which carries a first main cam for the first single-arm lever and a second main cam for the second single-arm lever, and
wherein a second axis is a pivoting axis of the first single-arm lever and the second single-arm lever,
wherein the cam carrier is formed as a drive shaft of a motor arranged between the first main cam and the second main cam and rotatably supported in the first single-arm lever and the second single-arm lever and driven by the motor which is arranged perpendicular to the first axis and the second axis.

2. The door handle arrangement according to claim 1 , wherein the main cam has at least first and second cam portions with different curve shapes.

3. The door handle arrangement according to claim 2 , wherein the first cam portion has a first curve shape that the main cam and the lever are arranged to be spaced apart from one another in the non-use position.

4. The door handle arrangement according to claim 2 , wherein the second cam portion has a second curve shape that the main cam and the lever can be moved relative to one another in order to move the handle element in an intermediate position or the use position.

5. The door handle arrangement according to claim 2 , wherein the first cam portion is designed such that a rotation of the main cam according to a first rotational movement in a first rotational angle range of 160° to 200° causes a first opening movement of the handle element in a range of 4 mm to 7 mm.

6. The door handle arrangement according to claim 2 , wherein the second cam portion is designed such that a rotation of the main cam according to a second rotational movement in a second rotational angle range of 160° to 200° causes a second opening movement of the handle element in a range of 25 mm to 30 mm.

7. The door handle arrangement according to claim 1 , wherein the at least one main cam is designed as a disc or roller.

8. The door handle arrangement according to claim 1 , wherein the adjusting mechanism and the handle element and the carrier element are in operative connection with one another in the use position of the handle element such that the handle element is fixed in the use position.

9. The door handle arrangement according to claim 1 , wherein the adjusting mechanism comprises at least one adjusting arrangement through which the handle element is fixed under tension at least in the use position.

10. The door handle arrangement according to claim 1 wherein the adjusting mechanism comprises a main axis about which the lever is mounted on the carrier element and the lever is movably mounted relative to the carrier.

11. The door handle arrangement according to claim 1 , wherein the cam carrier comprises at least one auxiliary cam arranged thereon for spring decoupling.

12. The door handle arrangement according to claim 1 , wherein the cam carrier is guided in each cam guide when the handle element is adjusted between the non-use position and the use position.

13. The door handle arrangement according to claim 1 , wherein the carrier element comprises at least one handle guide, in or on which the handle element is guided when it is adjusted between the non-use position and the use position.

14. A vehicle door having at least one door handle arrangement according to claim 1 .

15. The door handle arrangement according to claim 1 , wherein the arms have
an upper portion and a lower portion, wherein the profile extends between the upper portions and the pivot bearing extends between the lower portions.

16. The door handle arrangement according to claim 1 , wherein an upper portion of each arm is selectively biased by respective handle support elements each housed in a respective handle bar.

17. A door handle arrangement, comprising:
a carrier element,
a handle element which is movably arranged on the carrier element between a non-use position and a use position, and
an adjusting mechanism for adjusting the handle element relative to the carrier element,
wherein the adjusting mechanism comprises a lever mechanism having a first single-arm lever and a second single-arm lever and a cam carrier having at least one main cam in each arm for the controlled movement of the handle element between the non-use position and the use position, and
wherein each main cam interacts with a respective cam counter surface arranged on the first single-arm lever and the second single-arm lever and has a variable curve shape,
wherein each single-arm lever comprises a respective cam guide formed therein, and
wherein the adjusting mechanism comprises at least two axes;
where a first axis is a cam axis of the cam carrier which carries a first main cam for the first single-arm lever and a second main cam for the second single-arm lever, and
wherein a second axis is a pivoting axis of the first single-arm lever and the second single-arm lever,
wherein the cam carrier is formed as a drive shaft of a motor rotatably supported in the first single-arm lever and the second single-arm lever with respect to the carrier element around the cam axis and pivotably supported by the cam guide formed in the first single-arm lever and the second single-arm lever with respect to the first single-arm lever and the second single-arm lever around the pivoting axis.
