Abstract

A vehicle roof has a roof opening and a planar, transparent or translucent, roof element which seals the roof opening and is permanently connected to a roof frame of the vehicle roof. A ventilation device is integrated in the roof element and has a ventilation flap. The ventilation flap can be pivoted between a closed position in which the ventilation flap seals a ventilation opening and an open position in which the ventilation flap exposes the ventilation opening. A vehicle is equipped with a vehicle roof of this type.

Claims (51)

1 . A vehicle roof, comprising:

a roof opening;

a planar, transparent or translucent, roof element that closes the roof opening;

a roof frame of the vehicle roof, the roof element being connected to the roof frame in a fixed manner;

an interior roof liner;

a ventilation device having a ventilation flap, the ventilation device being integrated in the roof element, wherein the ventilation flap is pivotable between a closed position, in which the ventilation flap closes a ventilation opening, and an open position, in which the ventilation flap opens the ventilation opening; and

a rotatable roller blind extendible relative to the vehicle roof, wherein at least one portion of the roller blind is equipped with an air-permeable net fabric to provide for air exchange between an environment external to the vehicle and an interior of the vehicle when the roller blind is extended relative to the vehicle roof;

wherein the roller bind is arranged between the roof liner and the roof element;

wherein the ventilation device is offset longitudinally in a direction of vehicle travel from an opening in the roof liner, and wherein an air exchange gap formed between the roof liner and the vehicle roof traverses the longitudinal offset, via which air exchange occurs between the environment external to the vehicle and the interior of the vehicle; and

wherein a wall separates the roller blind in a retracted position from the air exchange gap.

2 . The vehicle roof according to claim 1 , wherein

the ventilation flap is pivotable into the open position such that an edge of the ventilation flap is lowered below a roof surface of the vehicle roof.

3 . The vehicle roof according to claim 1 , wherein

the ventilation flap is pivotable such that the ventilation opening faces the roof element or faces away from the roof element.

4 . The vehicle roof according to claim 1 , wherein

the ventilation device is integrated in a cut-out in the roof element and/or in a cut-out in a screen.

5 . The vehicle roof according to claim 1 , wherein

the ventilation device has a drive, which drive is connected to the ventilation flap in order to pivot the ventilation flap between the closed position and the open position.

6 . The vehicle roof according to claim 5 , wherein

the ventilation flap is coupled to the drive via a lever device.

7 . The vehicle roof according to claim 1 , wherein

the ventilation flap has cover plates.

8 . The vehicle roof according to claim 1 , wherein

the roof element comprises a glass panel.

9 . A vehicle comprising a vehicle roof according to claim 1 .

10 . A vehicle roof, comprising:

a roof opening;

a planar, transparent or translucent, roof element that closes the roof opening;

a roof frame of the vehicle roof, the roof element being connected to the roof frame in a fixed manner;

a ventilation device having a ventilation flap, the ventilation device being integrated in the roof element, wherein

the ventilation flap is pivotable between a closed position, in which the ventilation flap closes a ventilation opening, and an open position, in which the ventilation flap opens the ventilation opening;

the ventilation device has a housing, within which the ventilation flap is mounted so as to be pivotable about a pivot axis, and

a water channel integrated internally within the housing is configured to conduct and discharge water from the housing.

11 . The vehicle roof according to claim 10 , wherein

the ventilation flap is pivotable into the open position such that an edge of the ventilation flap is lowered below a roof surface of the vehicle roof.

12 . The vehicle roof according to claim 10 , wherein

the ventilation flap is pivotable such that the ventilation opening faces the roof element or faces away from the roof element.

13 . The vehicle roof according to claim 10 , wherein

the ventilation device is integrated in a cut-out in the roof element and/or in a cut-out in a screen.

14 . The vehicle roof according to claim 10 , wherein

the ventilation device has a drive, which drive is connected to the ventilation flap in order to pivot the ventilation flap between the closed position and the open position.

15 . The vehicle roof according to claim 10 , wherein

the ventilation flap is coupled to the drive via a lever device.

16 . The vehicle roof according to claim 10 , wherein

the ventilation flap has cover plates.

17 . The vehicle roof according to claim 10 , wherein

the roof element comprises a glass panel.

18 . A vehicle comprising a vehicle roof according to claim 10 .

19 . The vehicle roof according to claim 1 , wherein the ventilation flap is pivotable into the open position such that an edge of the ventilation flap is raised above a roof surface of the vehicle roof.

20 . The vehicle roof according to claim 10 , wherein

the ventilation flap is pivotable into the open position such that an edge of the ventilation flap is raised above a roof surface of the vehicle roof.
