A modular door for a vehicle HVAC system includes a door plate, a first shaft, and a second shaft. The door plate has a front surface extending between an upper edge surface and a lower edge surface. The upper edge surface defines a first array of keyed orifices. The lower edge surface defines a second array of keyed orifices. The first shaft has a first keyed protrusion that is disposed within a first keyed orifice of the first array of keyed orifices. The second shaft has a second keyed protrusion that is disposed within a first keyed orifice of the second array of keyed orifices. The first keyed orifice of the first array of keyed orifices and the first keyed orifice of the second array of keyed orifices form a pair of axially aligned keyed orifices.

Proposed is a headliner air vent device for a vehicle. A housing includes a first outlet through which air is discharged and a second outlet comparted by an inner cover and having a configuration by which air is discharged through outside the first outlet. An air guide supporter is rotatable inside the housing. An air guide is positioned to face an outer cover by which the second outlet is defined. The air guide is configured to move upwards or downwards in response to rotation of the air guide supporter to selectively open or close the second outlet.

A modular door kit for a vehicle HVAC system includes first, second, and third subcomponents. The first subcomponent defines a receptacle and is configured to be standardized for first and second door configurations. The second subcomponent has a first protrusion and is configured to be standardized for the first door configuration but not the second door configuration. The first protrusion is configured to engage the receptacle to rigidly affix the position of the second subcomponent relative to the first subcomponent to form the first door configuration. The third subcomponent has a second protrusion and is configured to be standardized for the second door configuration but not the first door configuration. The second protrusion is configured to engage the receptacle to rigidly affix the position of the third subcomponent relative to the first subcomponent to form the second door configuration.

A modular door for a vehicle HVAC system includes a first subcomponent, a second subcomponent, and a customized subcomponent. The first subcomponent forms a first portion of the modular door and is configured to be standardized for first and second vehicle HVAC systems. The second subcomponent forms a second portion of the modular door and is configured to be standardized for the first and second vehicle HVAC systems. The customized subcomponent is configured to separate the first subcomponent from the second subcomponent. The customized subcomponent is also configured to connect the first subcomponent to the second subcomponent such that the modular door is configured for the first vehicle HVAC system.

An air vent for introducing air into a motor vehicle interior includes an inlet opening, through which an incoming air flow enters the air vent, an outlet opening, through which an air flow exits the air vent, and an adjuster, which is fluidically and operatively connected to the inlet opening and the outlet opening. The adjuster has at least one entry, which is fluidically and operatively connected to the inlet opening. The adjuster has at least two exits, which are spaced apart from each other and from each of which an open air stream exits into the outlet opening. The adjuster is designed to align the open air streams to a focal point and the adjuster is designed to be located outside of a field of view of the motor vehicle interior.

An air-treatment system for a confined environment, in particular the cabin of a vehicle, includes: a supply unit including an inlet port, a delivery port, and a purge port, the supply unit being configured for delivering air to said confined environment through the delivery port; and a first filtering device having a first filtration level, and a second filtering device having a second filtration level, each of the first and second filtering devices being arranged in fluid communication with the inlet port of said supply unit at a circuit node. A single flow-control valve determines inlet flow through one or other of the filtering devices.

Disclosed is an air conditioner for a vehicle. The present invention provides an air conditioner for a vehicle capable of introducing indoor air and outdoor air simultaneously or selectively by forming a double-layer flow in an air conditioner case and capable of separately controlling the temperatures of a front seat and a rear seat.

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.

An air vent for a vehicle may include: a duct having a passage through which air is moved; a first adjuster rotatably installed in the duct, and configured to guide a discharge direction of air while rotating in a side-to-side direction; a second adjuster rotatably installed in the duct with the first adjuster, and configured to guide a discharge direction of air while rotating in an up and down direction or block an air flow passing through the duct; and a driving unit connected to the second adjuster and configured to supply power to rotate the second adjuster.
