Abstract

An air flap for an air flap assembly for a vehicle front is provided. The air flap has a front face and a lateral face having a slotted guide system. The air flap blocks an air inlet in the vehicle front through the front face in a closed position and opens the air inlet in an open position. The air flap is rotatable from the closed position into the open position by a rotary movement about an axis of rotation by way of a driver of an actuator, which driver can be guided in the slotted guide system. The slotted guide system located on the lateral face of the air flap has a tapered portion, so that the slotted guide system and the driver have substantially no play in relation to one another in the region of the tapered portion.

Claims (19)

1. A component of an air flap arrangement of a vehicle front, comprising: an air flap having a front surface and a side surface with a slotted guide, wherein the air flap blocks an air inlet of the vehicle front by way of the front surface in a closed position and releases the air inlet in an open position, the air flap is rotatable from the closed position into the open position by way of a rotational movement about a pivot pin via a driver of an actuator, which driver is guidable in the slotted guide, and the slotted guide, which is arranged on the side surface of the air flap, has a tapered middle portion, such that the slotted guide and the driver have substantially no play with respect to one another in a region of the tapered middle portion.

2. The component according to claim 1 , wherein

the side surface of the air flap has a resilient configuration in the region of the tapered portion.

3. The component according to claim 2 , wherein

the side surface of the air flap has a recess in the region of the tapered portion, to provide the side surface of the air flap with the resilient configuration in the region of the tapered portion.

4. The component according to claim 1 , wherein

the slotted guide has a first end stop for the driver in a first region which adjoins the tapered portion and in which the driver is arrangeable in the closed position and the open position.

5. The component according to claim 4 , wherein

the slotted guide has a second end stop for the driver in a second region which adjoins the tapered portion and in which the driver is arrangeable in a position in which the air flap is substantially half open.

6. The component according to claim 5 , wherein

the second end stop for the driver is arranged further away from the pivot pin than the first end stop, and

the tapered portion extends from the first to the second end stop.

7. The component according to claim 1 , wherein

the pivot pin runs substantially in a vehicle width direction.

8. The component according to claim 7 , wherein

the rotational movement, in order to move the air flap from the closed into the open position, comprises a rotation of the air flap upward in a vehicle vertical direction about the pivot pin which runs in the vehicle width direction.

9. An actuator for an air flap, comprising: a driver configured to be guided in a slotted guide, having a tapered middle portion, arranged on a side surface of an air flap that blocks an air inlet of a vehicle front, wherein the driver has a resilient configuration so as to elastically deform when passing through the tapered middle portion.

10. A system, comprising: an actuator; and an air flap having a front surface and a side surface with a slotted guide, wherein the air flap blocks an air inlet of a vehicle front by way of the front surface in a closed position and releases the air inlet in an open position, the air flap is rotatable from the closed position into the open position by way of a rotational movement about a pivot pin via a driver of the actuator, which driver is guided in the slotted guide, and the slotted guide, which is arranged on the side surface of the air flap, has a tapered middle portion, such that the slotted guide and the driver have substantially no play with respect to one another in a region of the tapered middle portion, wherein the actuator is configured to rotate the air flap from the closed position into the open position and into at least one intermediate position of the air flap situated between the closed and the open position by way of the rotational movement about the pivot pin of the air flap via the driver which is guided in the slotted guide, and the driver is situated in the at least one intermediate position of the air flap in that region of the tapered middle portion of the slotted guide, in which the driver and the slotted guide have substantially no play with respect to one another.

11. An actuator for an air flap arrangement of a vehicle front, comprising: an air flap having a front surface and a side surface, the side surface being driven with a driver, wherein the air flap blocks an air inlet of the vehicle front by way of the front surface in a closed position and releases the air inlet in an open position, wherein the actuator is to be connected to the air flap by way of a connecting element with a slotted guide, in which the driver is guidable, in such a way that the air flap is rotatable from the closed position into the open position by way of a rotational movement about a pivot pin, and wherein the slotted guide, which is arranged on the connecting element of the actuator, has a tapered middle portion such that the slotted guide and the driver have substantially no play with respect to one another in the region of the tapered middle portion.
