Abstract
The invention relates to an air flap for a ventilation, heating or air conditioning system of a motor vehicle. The flap has a shut-off surface extending between two outer edges, each having a curved or vaulted profile. End sections of the first edge adjoin the end sections of the second edge, and the end sections are joined to a pivot axis. In order, in particular, to obtain a compact construction for the air conditioning system, the air flap preferably has a shape in which a first area (A) enclosed by the first, outer edge and the pivot axis is larger than a second area (B) enclosed by the second, outer edge and the pivot axis. An air flap of this type is used, in particular, as a fresh-air/circulating-air flap.
Claims14
An air flap for a ventilation, heating or air conditioning system of a motor vehicle, the air flap comprising:
- a pivotable blocking surface for blocking air flow, defined by a frame having first and second edges connected to the surface, said first and second edges having a vaulted profile and each edge including a pair of endpieces, each endpiece adjoining one of the pair of endpieces of the other edge at a pivot axis for the surface to thereby form the frame;
- and
- wherein a first area defined by the first edge and the pivot axis is greater than a second area defined by the second edge and the pivot axis.
A system for guiding air in a ventilation, heating or air conditioning system of a motor vehicle, comprising:
- an air guiding housing;
- and
- an air flap comprising a pivotable blocking surface for blocking air flow, defined by a frame having first and second edges connected to the surface, said first and second edges having a vaulted profile and each edge including a pair of endpieces, each endpiece adjoining one of the pair of endpieces of the other edge at a pivot axis for the surface to thereby form the frame;
- wherein a first area defined by the first edge and the pivot axis is greater than a second area defined by the second edge and the pivot axis;
- and
- wherein the air flap is mounted rotatably in the air-guiding housing to form a mixing flap for selectively closing off air flow.
