A kinematics system driven by an actuator comprises a cam configured to rotate about an axis of rotation thereof. A cam track formed in the cam extends circumferentially through more than 360 degrees of angular displacement relative to the axis of rotation of the cam. The kinematics system also comprises a follower having a pin slidably disposed in the cam track of the cam. The cam track extending circumferentially through more than 360 degrees of angular displacement relative to the axis of rotation of the cam establishes a minimized pressure angle formed between the pin of the follower and a surface of the cam track engaging the pin.

An air-handling system for a heating, ventilation, and air conditioning system of a vehicle includes a main housing comprising a conditioning section, a mixing section, and a delivery section having a flow of air passing therethrough. The delivery section includes a conduit branching into a windshield defrost pathway and a demist pathway, the windshield defrost pathway leading to windshield defrost vents of a passenger compartment of the vehicle and the demist pathway leading to side window defrost vents of the passenger compartment. A control door rotatably disposed in the conduit is adjustable through a range of rotational positions wherein a flow area through the windshield defrost pathway is variably restricted while the demist pathway remains unobstructed. The control door is further adjustable to a position wherein the windshield defrost pathway and the demist pathway are closed.

Method of distributing air ventilation in a vehicle

An air-handling system for a heating, ventilation, and air conditioning system comprising includes a main housing, a temperature door, a mode door, and a control mechanism. The temperature door is disposed in a mixing and conditioning section of the main housing to control a temperature of a flow of air to a delivery section of the main housing. The mode door is disposed in the delivery section of the main housing to control a flow of air through an upper conduit and a lower conduit. The control mechanism cooperates with each of the temperature door and the mode door. The control mechanism includes a single actuator configured to independently control each of the temperature door and the mode door to provide independent temperature control for each of a high mode, a low mode, and a mixed mode of operation.

HVAC kinematics to provide temperature and mode control with one actuator

A climate control system for a vehicle comprises a housing and a diverter. The housing has a first conduit formed therein. The first conduit includes a first subconduit formed in an intermediate portion of the first conduit and a second subconduit disposed adjacent an end of the first subconduit. The diverter is rotatably disposed within the first conduit, and includes a first member having an outer edge and an offset edge. The outer edge is disposed on a first planar portion of the first member and configured to sealingly contact a wall of the first subconduit when the diverter is in a first position. The offset edge is disposed on a second planar portion of the first member and configured to sealingly contact a portion of the second subconduit when the diverter is in the first position.

Multi-planar air diverter

A temperature door for an air handling system of a heating, ventilating, and air conditioning system for a vehicle includes a first sealing surface and a second sealing surface spaced apart from the first sealing surface. A third surface extends between the first sealing surface and the second sealing surface. A plurality of cells is formed on the third surface.

Temperature door for HVAC to facilitate blending

A control module for a heating, ventilating, and air conditioning system for a vehicle is disclosed, wherein a cost and a space requirement for the system are minimized and a control of temperature, mode, and volume of an air flow in a passenger compartment of the vehicle is optimized.
