Abstract

A motor vehicle door handle assembly includes a carrier, a handle body, pivotable about an axis of rotation and movable from an idle position into an end position, and a force-increasing device, which, during movement of the handle body from the idle position into the intermediate position, produces a resistance force counteracting the movement of the handle body. The force-increasing device includes a force-increasing element, producing the resistance force and fastened to the handle body, a resistance element, interacting with the force-increasing element and mounted on the handle body, and a movement element, which, during movement of the handle body from the idle position into the intermediate position, moves the resistance element translationally toward the force-increasing element against the resistance force produced by the force-increasing element and, during movement of the handle body from the end position into the idle position, moves the resistance element rotationally.

First claim

1 . Door handle assembly of a motor vehicle, comprising a carrier which can be fastened on a door or trunk lid of the motor vehicle, a handle body, which is mounted on the carrier for pivoting about an axis of rotation and can be moved from an idle position into an end position, and a force-increasing device, which is designed, during movement of the handle body from the idle position into the intermediate position, to produce a resistance force counteracting the movement of the handle body,
wherein the force-increasing device comprises a force-increasing element, which produces the resistance force and is fastened to the handle body, a resistance element, which interacts with the force-increasing element and is mounted on the handle body, and a movement element, which is designed, during movement of the handle body from the idle position into the intermediate position, to move the resistance element translationally toward the force-increasing element against the resistance force produced by the force-increasing element relative to the axis of rotation and, during movement of the handle body from the end position into the idle position, to move the resistance element rotationally relative to a rotational axis of the handle body.

2 . Door handle assembly according to claim 1 , wherein the movement element is designed as a movement projection projecting from a base body mounted on the carrier.

3 . Door handle assembly according to claim 1 , wherein the movement element is pivotably mounted on the carrier via a pivot axis, wherein the handle body and the movement element are coupled together so as to transmit a movement and rotate in contrary directions about the axis of rotation and the pivot axis during movement of the handle body.

4 . Door handle assembly according to claim 3 , wherein the handle body has at least one pivot lever connected to the axis of rotation, on which a coupling recess is formed, wherein the movement element has at least one coupling arm, on which a coupling projection is formed, which is arranged in the coupling recess of the at least one pivot lever of the handle body.

5 . Door handle assembly according to claim 1 , wherein the resistance element has a functional body having a support surface, wherein the functional body is inserted at least in sections in a receiving frame formed on the handle body and the force-increasing element is arranged between the support surface of the functional body and a mounting surface formed on the handle body.

6 . Door handle assembly according to claim 5 , wherein the functional body of the resistance element has at least one support element projecting laterally from the functional body, wherein the at least one support element is arranged lying on the receiving frame in the idle position of the handle body and the force-increasing element presses the supporting element onto the receiving frame.

7 . Door handle assembly according to claim 6 , wherein the handle body has at least one first guide surface and at least one second guide surface which is parallel to the at least one first guide surface, wherein a ramp surface is formed on the functional body, which ramp surface is formed on the side of the functional body facing away from the support surface and which rises in a direction pointing towards the carrier.

8 . Door handle assembly according to claim 7 , wherein during movement of the handle body from the idle position into the intermediate position, the movement element rests on the ramp surface and is designed to move the functional body of the resistance element linearly and/or translationally against the resistance force of the force-increasing element in the direction of the force-increasing element with respect to the axis of rotation of the handle body along the at least one first guide surface and the at least one second guide surface.

9 . Door handle assembly according to claim 7 , wherein during movement of the handle body beyond the intermediate position up to the end position, the movement element is spaced apart from the ramp surface beyond the intermediate position up to the end position and the at least one support element is arranged lying on the receiving frame.

10 . Door handle assembly according to claim 5 , wherein two pivot pins are formed on two opposite sides of the functional body of the resistance element, which are rotatably mounted at least in the idle position of the handle body in corresponding bearing receptacles, which are formed in the receiving frame of the handle body, wherein the pivot pins form the rotational axis.

11 . Door handle assembly according to claim 10 , wherein during movement of the handle body from a position lying between the intermediate position and the end position into the idle position, the movement element comes into contact with the functional body and is designed to rotationally move the functional body having its two pivot pins arranged in the corresponding bearing receptacles against the direction of rotation of the handle body in the bearing receptacles with respect to the rotational axis.

12 . Door handle assembly according to claim 10 , wherein the functional body has two guide arms formed on opposite sides and angled and the handle body has two guide recesses which extend in an actuation direction of the handle body, wherein during movement of the handle body from a position lying between the intermediate position and the end position toward the idle position, the two guide arms are arranged lying and guided in the guide recesses of the handle body.
