Abstract

An air vent for a ventilation system in a vehicle is disclosed that has an air circulation chamber (1) defined by a housing (9) that has a generally bulged shape. An inflow duct (2) is connected to this housing and opens into the circulation chamber (1), the housing having a perforated wall area (3). An air stream, in use, enters the circulation chamber (1) through inflow duct (2), circulates through the air circulation chamber and exits through the perforated wall area. The air vent further comprises a movable air deflection member disposed to deflect the air stream transversely to an axial direction of the inflow duct.

Claims

1. An air vent for a ventilation system in a vehicle, comprising an air circulation chamber (1) defined by a housing that has a generally bulged shape, an inflow duct (2) connected to said housing and opening into the circulation chamber (1), the housing having a perforated wall area (3), an air stream, in use, entering the circulation chamber (1) through said inflow duct (2), circulating through the air circulation chamber and exiting through the perforated wall area (3), and further comprising a movable air deflection member (4;

6) disposed to deflect the air stream transversely to an axial direction of said inflow duct (2), wherein the air deflection member (4) has a generally ball-shaped body which is rotatably accommodated in an annular bearing seat in the end of the inflow duct (2), and which defines a channel section of cylindrical shape that extends diametrically through the ball-shaped body.

2. The air vent according to claim 1, wherein an air guide (5) is arranged in the air circulation chamber (1) adjacent to the perforated wall area (3).

3. The air vent according to claim 2, wherein the air guide (5) comprises a continuous wall that is spaced from and extends parallel to said perforated wall area.

4. The air vent according to claim 2, wherein the air guide includes a set of curved baffle members (11) at fixed positions in the air circulation chamber upstream of said perforated wall area (3).

5. The air vent according to claim 2, wherein the air guide includes a set of straight baffle members (12) pivotally mounted in the air circulation chamber upstream of said perforated wall area (3).
