A vehicle HVAC system delivers airflow to a vehicle occupant cabin having a front row and a rear row. The vehicle HVAC system includes a casing, a front duct, a shifter base assembly and a distribution duct. The front duct defines an airflow passageway that is fluidly coupled to the casing. The shifter base assembly is disposed in the vehicle occupant cabin and includes a base housing defining an airflow passageway that is fluidly coupled to the front duct. The distribution duct defines an airflow passageway that is fluidly coupled to the shifter base assembly and the rear row of the vehicle occupant cabin. The airflow passageways of the casing, the front duct, the base housing and the distribution duct form a continuous passageway through which air flows into the rear row of the vehicle occupant cabin.

A device for controlling the temperature of the neck region of a user of a vehicle seat. The device includes an air conveying device that is configured to convey air to a temperature control region, a temperature control device that is configured to control the temperature of the air to be conveyed to the temperature control region, and a control device that is configured to automatically control the air conveying device and the temperature control device.

A component system for ventilating a trunk compartment area and a motor vehicle for the purpose of cooling at least one unit located in the trunk compartment area and a motor vehicle, in particular a passenger motor vehicle. The component system has a loading floor for storing objects, the trunk compartment area can be arranged below the loading floor, and a first component which delimits the trunk compartment area in sections, in particular a bodyshell component. Between the loading floor and the first component, at least one passage is arranged for guiding an air flow into the trunk compartment area.

A device for controlling the air flow from an air outlet of a heating and/or ventilation and/or air-conditioning system of a motor vehicle. The air outlet has an air discharge opening which is for discharging air into an inner vehicle space and over which there extends at least one elongate slat which can be pivoted about a longitudinal axis in order to influence an air flow flowing through the air discharge opening and whose pivot position can be adjusted by at least one adjustment mechanism which is coupled to the slat. At least one actuation mechanism, which is fitted to a vehicle seat when the vehicle seat is mounted in the inner vehicle space, moves into mechanical operational engagement with the adjustment mechanism and brings about an adjustment of the at least one slat in accordance with a position of the vehicle seat with respect to the inner vehicle space.

A method for operating an air conditioning system, which may include a heating device, to condition air in a vehicle interior of a motor vehicle. At least one first air path and at least one second air path may each fluidically communicate with the air conditioning system and each open out into the vehicle interior. The method may include guiding the air from the vehicle interior via one of (i) the at least one first air path and (ii) the at least one second air path to the air conditioning system as a function of an operating state set in the air conditioning system. The method may also include guiding the air from the air conditioning system via the other of the one of (i) the at least one first air path and (ii) the at least one second air path into the vehicle interior.

An air distribution plenum for controlling air flow in a vehicle HVAC system includes an air inlet and first and second air outlets. A movable member substantially blocks the first and second air outlets when in a first position, blocks only the first air outlet in a second position, blocks only the second air outlet in a third position, and permits air to flow through both the first and second air outlets when in a fourth position.

A utility vehicle is described having front and rear passenger area, and an HVAC system provides treated air to both front and rear areas. The front area includes a tunnel extending longitudinally rearwardly, and a low profile duct extends within the tunnel to communicate treated air to the rear passenger area. The frame has been modified to mount a drive shaft carrier bearing to maximize the arear under the tunnel for hose routing. The frame has been modified to maximize the ingress area for the foot of the rear passenger. The frame has been modified to better seal the vehicle when doors are utilized.

The present invention relates to an air conditioning system for a vehicle in which an air-conditioning module having an air-conditioning case and a blower unit is disposed at a side of an engine room relative to a dash panel, and a distribution duct having a defrost vent, a face vent, and a floor vent is disposed in the interior of a vehicle relative to the dash panel so as to distribute cold air and hot air discharged from the air-conditioning case into the interior of the vehicle, wherein the floor vent is placed on one side of an area, in which a relatively large amount of hot air flows, in a mixing chamber of the distribution duct where cold air and hot air are mixed, i.e. a side adjacent to the dash panel.

In an instrument panel provided in a vehicle cabin front section, a face that projects into a vehicle cabin is formed with a T-shape in vehicle rear view. An air-conditioning unit of a vehicle air-conditioning device is provided at an inside of the instrument panel. In the vehicle air-conditioning device, a foot blower outlet provided on the instrument panel blows an air-conditioned airflow toward the feet of a front seat occupant, and an interior air intake provided on the instrument panel takes in air from inside the vehicle cabin to generate the air-conditioned airflow. The foot blower outlet is formed in a lower portion of a side wall at a vehicle width direction central portion of the instrument panel.

A system for vehicle component cooling includes a main body defining a passenger compartment to support passengers of the vehicle. The system also includes a heating, ventilation, and air conditioning (HVAC) unit to output conditioned air into the passenger compartment. The system also includes a vehicle component to generate heat and having a component temperature. The system also includes a cooling channel having an inlet located in the passenger compartment and an outlet to output the conditioned air from the passenger compartment towards the vehicle component. The system also includes at least one sensor to detect data corresponding to the component temperature of the vehicle component. The system also includes an electronic control unit (ECU) to control the HVAC unit to increase or decrease a cabin temperature to adjust the component temperature based on the detected data.
