Document Type and Number:
WIPO Patent Application WO/2024/034814
Kind Code:
A1
Abstract:
A flap system for a heating, ventilation and air-conditioning unit for circulating-air/fresh-air control in a motor vehicle, the HVAC unit having flow ducts for circulating air and for fresh air and a mixing chamber in which circulating air and fresh air are mixed with one another for ventilating a vehicle interior, the flap system having two rotary flaps, each adjustable about an axis of rotation, and an actuator, by which one of the two rotary flaps is driven directly for adjustment, a drive shaft of the directly driven rotary flap having a cam disc with a guide track in which a pendulum lever mechanically coupled to a drive lever of the further rotary flap is guided in such a way that a rotation of the cam disc effects an indirect drive for adjusting the further rotary flap, in which case the rotary flap can be moved in each case between a first closed position and a second closed position into an open position wherein the rotary flap is a fresh air rotary flap associated with the flow channel for fresh air for influencing a fresh air flow and wherein the other rotary flap is a circulating air rotary flap associated with the flow channel for circulating air for influencing a circulating air flow.
