Ventilation flap for a vehicle

1 . A ventilation flap arrangement of a vehicle front, comprising:

a ventilation flap that blocks an air inlet of the vehicle front in a closed position and releases the air inlet in an open position, the ventilation flap being rotatable from the closed position into the open position by a circular rotational movement about a single rotational axis arranged rearwardly behind the ventilation flap in a longitudinal vehicle direction via an actuator, wherein

the ventilation flap is divided into two mutually adjacent regions in a vertical vehicle direction,

a first, upper, region of the two regions in the vertical vehicle direction extends substantially in the vertical vehicle direction, and

a second, lower, region of the two regions in the vertical vehicle direction extends from the first region in the longitudinal vehicle direction rearwardly and, in the vertical vehicle direction, downwardly.

2 . The ventilation flap arrangement according to claim 1 , wherein

the second region extends from the first region in a curved manner rearwardly in the longitudinal vehicle direction and downwardly in the vertical vehicle direction.

3 . The ventilation flap arrangement according to claim 1 , wherein

the rotational axis extends substantially in a vehicle width direction.

4 . The ventilation flap arrangement according to claim 1 , wherein

the rotational movement that moves the ventilation flap from the closed position into the open position involves a rotation of the ventilation flap about the rotational axis, which rotational axis extends in a vehicle width direction, upwardly in the vertical vehicle direction.

5 . A ventilation flap arrangement of a vehicle front, comprising:

a ventilation flap that blocks an air inlet of the vehicle front in a closed position and releases the air inlet in an open position, the ventilation flap being rotatable from the closed position into the open position by a circular rotational movement about a single rotational axis via an actuator, wherein

the ventilation flap is divided into two mutually adjacent regions in a vertical vehicle direction,

a first, upper, region of the two regions in the vertical vehicle direction extends substantially in the vertical vehicle direction,

a second, lower, region of the two regions in the vertical vehicle direction extends from the first region in a longitudinal vehicle direction rearwardly and, in the vertical vehicle direction, downwardly, and

a lowest location of the first region of the ventilation flap in the vertical vehicle direction is located at a same height in the vertical vehicle direction as the rotational axis so that the first region and a horizontal which extends through the rotational axis parallel with the longitudinal vehicle direction substantially define a right angle.

6 . The ventilation flap arrangement according to claim 5 , wherein

the second region extends from the first region in a curved manner rearwardly in the longitudinal vehicle direction and downwardly in the vertical vehicle direction.

7 . The ventilation flap arrangement according to claim 5 , wherein

the second region extends from the first region in a curved manner rearwardly in the longitudinal vehicle direction and downwardly in the vertical vehicle direction with a radius of curvature which corresponds to a spacing of the lowest location of the first region from the rotational axis.

8 . A ventilation flap arrangement of a vehicle front, comprising:

a ventilation flap that blocks an air inlet of the vehicle front in a closed position and releases the air inlet in an open position, the ventilation flap being rotatable from the closed position into the open position by a circular rotational movement about a single rotational axis via an actuator, wherein

the ventilation flap is divided into two mutually adjacent regions in a vertical vehicle direction,

a first, upper, region of the two regions in the vertical vehicle direction extends substantially in the vertical vehicle direction, and

a second, lower, region of the two regions in the vertical vehicle direction extends from the first region in a longitudinal vehicle direction rearwardly and, in the vertical vehicle direction, downwardly,

in the closed position, the second region of the ventilation flap is in contact with an air guiding face of the vehicle front, which air guiding face is arranged in the vertical vehicle direction below the ventilation flap,

the air inlet has a first height (H 1 ), the air guiding face has a second, non-zero, height (H 2 ), the second region of the ventilation flap has a third height (H 3 ), and the first region of the ventilation flap has a fourth height (H 4 ),

the first height of the air inlet is greater than a sum of the third and fourth heights of the ventilation flap, and

the first height of the air inlet corresponds to a sum of the second, third and fourth heights.

9 . A vehicle front, comprising:

a ventilation flap arrangement according to claim 8 ; and

the air guiding face with which the second region of the ventilation flap is in contact in the closed position and which is arranged in the vertical vehicle direction below the ventilation flap in order to block an air inlet of the vehicle front.

10 . The vehicle front according to claim 9 , further comprising:

the actuator, which actuator is connected to the rotational axis of the ventilation flap and is configured to rotate the ventilation flap about the rotational axis from the closed position into the open position.

11 . A vehicle comprising the vehicle front according to claim 9 .
