Abstract

An air deflector bar extends parallel to an upper edge of a front windscreen of a motor vehicle. The air deflector bar includes an air deflection channel that extends along its length. The air deflection channel is concavely delimited in cross section by means of a first side that butts against the front windscreen and a second side that is connected to the first side and is at a distance from the first side. The inner surface of the second side of the air deflector bar is oriented toward an edge of a dashboard of the motor vehicle, which edge delimits the dashboard toward a passenger interior.

First claim

What is claimed:

1. An apparatus, comprising an air deflector bar that extends parallel to an upper edge of a front windscreen of a motor vehicle and incorporates an air deflection channel that is defined by a first side that butts against the front windscreen and a second side that is connected to the first side, wherein (a) an inner surface of the second side of the air deflector bar is oriented toward an edge of a dashboard of the motor vehicle, (b) said edge delimits the dashboard toward a passenger interior and said second side directs air toward said edge of said dashboard, (c) the inner surface of the second side of the air deflector bar is oriented toward the edge of the dashboard so that an air flow which flows upward along the front windscreen, impinges upon the air deflector bar and is deflected thereby toward the dashboard where said air flow is split up by the dashboard into two partial flows of approximately equal size, of which a first partial air flow is directed to air outlets of a windscreen heater in the dashboard and a second partial air flow is directed into the passenger interior, (d) an inner surface of the first side and the inner surface of the second side of the air deflector bar are approximately straight in cross section and are interconnected via a rounded surface of the air deflector bar so that the air deflection channel is a V-shape with a rounded bottom, (e) the first side and the second side of the air deflector bar are arranged at an angle α with a value of between 30° and 60° to each other, and (f) the air deflector bar is arranged to overlap a boundary between the front windscreen and a roof lining of the motor vehicle.

2. The apparatus as set forth in claim 1 , wherein the air deflector bar has a third side that overlaps the boundary between the front windscreen and the roof lining of the motor vehicle.

3. The motor vehicle incorporating the apparatus of claim 1 .

4. The motor vehicle incorporating the apparatus of claim 2 .
