An HVAC case for a vehicle including an airflow outlet defining a first outlet area having a first width and a first depth, and a second outlet area having a second width and a second depth. The first outlet area is larger than the second outlet area. A ramped surface is adjacent to the second outlet area. An airflow control door is movable to an open position, a partially closed position in which the airflow control door obstructs airflow through the first outlet area and permits airflow through the second outlet area, and a fully closed position in which the airflow control door obstructs airflow through both the first outlet area and the second outlet area.

A flap stopper for a rotatable flap for controlling an air flow may include a round bearing support disc, a round stopper support disc, stop elements, and connecting ribs. The stopper support disc may be spaced apart from the bearing support disc in an axial direction. The stop elements may be arranged on the stopper support disc. The connecting ribs may be arranged between the bearing support disc and the stopper support disc. The bearing support disc, the stopper support disc, the stop elements, and the connecting ribs may be formed as an integral plastic injection-molded part.

A blower unit includes a casing defining a first passage and a second passage, a first internal-external air switching member, a second internal-external air switching member, and a partition defining an opening. During a two-layer internal/external air mode, the first internal-external air switching member opens an external air inlet and closes an internal air inlet and the second internal-external air switching member closes the external air inlet and opens the internal inlet, so that the external air is directly introduced into the first passage through the external air inlet and the external air in the second passage is introduced into the first passage through the opening of the partition and the internal air is directly introduced into the second passage through the internal air inlet and the internal air in the first passage is introduced into the second passage through the opening of the partition.

An air handling system of a vehicle comprises a housing defining an inlet section. The inlet section includes a first inlet portion and a second inlet portion. The first inlet portion includes a first recirculation inlet configured to receive recirculated air originating from a passenger compartment of the vehicle and a first ambient air inlet configured to receive ambient air originating from an ambient environment. The second inlet portion includes a second recirculation inlet configured to receive recirculated air originating from the passenger compartment of the vehicle and a second ambient air inlet configured to receive the ambient air originating from the ambient environment. A first air distribution door and a first baffle door are disposed in the inlet section to selectively control a distribution of the recirculated air and the ambient air entering the first inlet portion. A second air distribution door and a second baffle door are disposed in the inlet section to selectively control a distribution of the recirculated air and the ambient air entering the second inlet portion.

The present invention relates to the technical field of automobile fittings, and discloses a foldable and flexible vent for an air conditioner, comprising a base, a hose and an air guide cylinder, wherein one end of the base communicates with the vent for the air conditioner, and the other end communicates with the hose; the air guide cylinder is arranged at one end of the hose away from the base; the vent further comprises an air damper and a rotating mechanism. The plurality of air dampers are distributed in a circular array in the air guide cylinder with the axis thereof as the center, and then adjusted by the synchronous angle of the rotating mechanism, so that the wind direction of the hose flowing into the air guide cylinder is uniformly discharged in a spiral manner, achieving the effect of simple, convenient and efficient uniform venting.

Described herein is air distributing device for an air conditioning unit of a motor vehicle, the device including: a housing defining an air intake chamber, on the housing there being formed an air inlet, a central air outlet, and two side air outlets. The device also includes a drum flap mounted rotatably about an axis (z) orthogonal to a direction that goes from the air inlet to the central air outlet. The flap is movable between a first position, wherein the air inlet is closed by the flap; a second position, wherein the two side air outlets are closed by the flap and an air flow between the air inlet and the central air outlet is allowed; and a third position, wherein the central air outlet is closed by the flap and an air flow between the air inlet and the side air outlets is allowed.

An air handling system of a vehicle comprises a housing defining an inlet section. The inlet section includes a recirculation inlet in fluid communication with a passenger compartment of the vehicle and a fresh air inlet in fluid communication with an ambient environment. An air distribution door is disposed in the inlet section for controlling a distribution of air entering the inlet section through the recirculation inlet and the fresh air inlet. A baffle door is disposed in the inlet section for selectively reducing a flow area through the fresh air inlet to accommodate a ram air pressure induced by motion of the vehicle relative to fresh air of the ambient environment.

A seat conditioning module for a seat conditioning assembly including an air mover, an intake port, outtake port, wherein at least one of the intake port, the outtake port, or both are in fluid communication with a seat surface. A valve assembly with at least two apertures movably disposed between the air mover and the at least one intake and at least one outtake ports. An actuation device for moving the valve assembly to control the passage of the fluid through the at least two apertures. An optional conditioning device in fluid communication with the air mover and the seat surface. A control device for at least controlling the position of the at least two apertures of the valve assembly, the activation of the optional conditioning device, the operation of the air mover, or any combination thereof.

An air handling system for a heating, ventilation, and air conditioning system of a motor vehicle includes a conduit configured to convey air from the air handling system to a vent of the air handling system. A control door is rotatably disposed in the conduit. The control door selectively rotates between a first position and a second position. The first position blocks passage of the air flowing through the conduit. The second position blocks passage of the air flowing through a first portion of the conduit and allows the air to flow through a second portion of the conduit. A control feature is disposed in the second portion of the conduit to control at least one of a volumetric flow rate and a pressure of the air flowing through the second portion.
