ABSTRACT:
An air vent for use in a motor vehicle passenger compartment, and in particular to an air vent with an air grill that can be rotated to a closed position. A housing has a first pivot bearing to which is connected a carrier with a second pivot bearing. An air grill with vanes has generally spherical peripheral surfaces and is connected to the second pivot bearing. The air grill may then be rotated about two orthogonal axes within the housing to vary the direction of the air flow entering the passenger compartment. The central vane has a circular periphery, and the air grill may also be rotated to a position in which this vane makes a seal with a compliant sealing section within the housing to close off the flow of air through the air vent.
