A door device for a vehicle, in particular a rail vehicle, comprising - a door frame forming a door opening plane and connecting an interior space of the vehicle to an exterior, - a first door leaf and a second door leaf which are each provided movably relative to the door frame, - wherein, in a closed state of the door device, o the first door leaf forms a first door sealing surface extending at least partially parallel to the door opening plane, and the second door leaf forms a second door sealing surface extending at least partially parallel to the door opening plane and cooperating with the first door sealing surface, or o the first door leaf forms a first door sealing surface extending obliquely to the door opening plane, and the second door leaf forms a second door sealing surface extending obliquely to the door opening plane and cooperating with the first door sealing surface, and - wherein the first door leaf and the second door leaf are designed such that in the closed state of the door device the second door sealing surface at least partially overlaps the first door sealing surface from the exterior, and the second door sealing surface can be lifted off the first door sealing surface by means of a lifting movement (a1; a2) of the second door leaf at least partially perpendicularly to the door opening plane, and - sealing means, which are arranged effectively between the door sealing surfaces (21, 31) in the closed state of the door device. - a door frame forming a door opening plane and connecting an interior space of the vehicle to an exterior, - a first door leaf and a second door leaf which are each provided movably relative to the door frame, - wherein, in a closed state of the door device, o the first door leaf forms a first door sealing surface extending at least partially parallel to the door opening plane, and the second door leaf forms a second door sealing surface extending at least partially parallel to the door opening plane and cooperating with the first door sealing surface, or o the first door leaf forms a first door sealing surface extending obliquely to the door opening plane, and the second door leaf forms a second door sealing surface extending obliquely to the door opening plane and cooperating with the first door sealing surface, and - wherein the first door leaf and the second door leaf are designed such that in the closed state of the door device the second door sealing surface at least partially overlaps the first door sealing surface from the exterior, and the second door sealing surface can be lifted off the first door sealing surface by means of a lifting movement (a1; a2) of the second door leaf at least partially perpendicularly to the door opening plane, and o the first door leaf forms a first door sealing surface extending at least partially parallel to the door opening plane, and the second door leaf forms a second door sealing surface extending at least partially parallel to the door opening plane and cooperating with the first door sealing surface, or o the first door leaf forms a first door sealing surface extending obliquely to the door opening plane, and the second door leaf forms a second door sealing surface extending obliquely to the door opening plane and cooperating with the first door sealing surface, - wherein the first door leaf and the second door leaf are designed such that in the closed state of the door device the second door sealing surface at least partially overlaps the first door sealing surface from the exterior, and the second door sealing surface can be lifted off the first door sealing surface by means of a lifting movement (a1; a2) of the second door leaf at least partially perpendicularly to the door opening plane, and - sealing means, which are arranged effectively between the door sealing surfaces (21, 31) in the closed state of the door device.
