More Information
Summary:An air vent includes a louver blade rotatable to adjusted positions by a motor. A control mechanism which connects the motor with the louver blade includes a control member connected to the motor, and a rotation transmitting member connecting the control member to the louver blade. The control member and rotation transmitting member are rotatable about a common axis. The rotation transmitting member and control member are capable of limited relative rotation in the event that an unwanted external force is applied to the louver blade, in order to isolate the motor from that external force. Spring-biased return blocks engage an elliptically shaped portion of the rotation transmitting member to return the louver blade to a prescribed angular relationship to the control member when the external force is relieved.
