A vehicle ventilation system includes a seating assembly including a seat blower. The seat blower pulls air away from a seating surface. A cabin blower is configured to circulate air in a cabin. A controller is configured to monitor a flow rate of the cabin blower. The controller is also configured to control a seat blower flow rate as a function of a cabin blower flow rate.

A vehicle air conditioning apparatus is provided which includes: a plurality of seat air conditioning units configured to selectively perform cooling or heating per corresponding seat among a plurality of seats installed in a cabin, respectively; and a plurality of exhaust ducts for discharging, outside the cabin, part of air used in the plurality of seat air conditioning units. An exhaust duct of a given one of the plurality of seat air conditioning units is connected to an air inlet of another seat air conditioning unit.

An armrest assembly includes a body portion having a cushioned component, wherein the cushioned component includes first and second portions spaced-apart from one another. The cushioned component includes a porous lattice matrix. A duct assembly includes a main inlet and first and second outlets that are operably coupled to the first and second portions of the cushioned component, respectively. The duct assembly further includes first and second channels fluidically coupled to the first and second outlets, respectively. An air diverter member is pivotally supported between first and second positions and includes a channel disposed therethrough. The channel of the air diverter member opens into the first channel when the air diverter member is in the first position, and opens into the second channel when the air diverter member is in the second position for directing airflow to the first and second outlets, respectively.

A stroller having a frame, a seat on the frame for receiving a child and a heating/cooling system operably coupled to the seat. The heating/cooling system includes a single heating and cooling element proximate the seat. A reversible compressor is operably coupled to the single heating and cooling element. A first coil operably coupled to the compressor. A reversible expansion valve is operably coupled to the first coil. The reversible expansion valve is operably coupled to the single heating and cooling element. A refrigerant circulates through the single heating and cooling element, reversible compressor, first coil and reversible expansion valve. The heating/cooling system provides a first operating configuration for cooling the seat by having the refrigerant within the single heating and cooling element absorb heat, and a second operating configuration for heating the seat by having the refrigerant within the single heating and cooling element dissipate heat.

Various embodiments include illustrative vehicle seats, systems, vehicles, and methods for circulating airflow through a vehicle seat. An illustrative vehicle seat includes a cushion. The cushion is adapted to provide airflow therethrough. The cushion defines a primary airflow path directed to a primary outlet formed in a supporting portion of the cushion. The supporting portion of the cushion is adapted to receive direct body contact with a vehicle occupant while the vehicle occupant is seated within the vehicle seat. The cushion also defines a secondary airflow path directed to a secondary outlet formed in a non-supporting portion of the cushion.

A wire harness connected to a sensor is positioned on a back surface of a pad of a vehicle seat supported by a panel. The vehicle seat (1) includes a panel (4); a pad (11, 51) supported by the panel; a skin material (12, 52) covering a front surface of the pad; and a sensor (32) provided between the front surface of the pad and the skin material for acquiring information on a seat occupant, wherein the pad is provided with a through hole (35, 58) passed from the front surface of the pad to a back surface of the pad, and a recess (45, 61) formed in the back surface of the pad and connected to the through hole, the wire harness connected to the sensor extending in the through hole and the recess.

A temperature control layer, for example for an interior trim of a vehicle or a vehicle part is disclosed. The temperature control layer includes an areal thermoelectrical temperature control arrangement with at least one thermoelectrical element and an air extraction arrangement with at least one air extraction duct. The at least one air extraction duct leads from an outside of the temperature control layer through the temperature control arrangement to an inside of the temperature control layer.

A seat air conditioner includes an air passage that is disposed in a seat of the vehicle, a blower that blows air into the air passage, an outlet through which the air flowing through the air passage is blown as a blown air toward a rear side of a vehicle interior along an upper surface of the seat, and a guide member that is disposed behind the outlet to be moveable between a first position and a second position. The guide member allows the blown air from the outlet to flow toward the rear side of the vehicle interior together with a surrounding air entangled by the blown air when the guide member is at the first position and guides the blown air from the outlet toward a ceiling side or a floor side of the vehicle interior when the guide member is at the second position. The guide member is retracted into a housing space defined in the seat when the guide member is at the first position. At least a portion of the guide member protrudes upward from the upper surface of the seat when the guide member is at the second position.

A vehicle air-conditioning apparatus includes: a duct disposed in a seat of a vehicle, air flowing through the duct from an air conditioning unit; a rear seat outlet formed on a back face of a backrest portion of the seat to blow out the air from the duct toward a rear seat of the vehicle; and an air flow deflection member that partitions the rear seat outlet into a first region and a second region to define a first passage through which the air flows from the duct through the first region in a first direction in a vehicle cabin and a second passage through which the air flows from the duct through the second region in a second direction more downward than the first direction in the vehicle cabin.

A vehicle occupant air curtain system includes a seat that has a seat cushion and a seat back. The seat back has a region that is configured to be arranged above an occupant shoulder. An air vent is supported on the seat back and is arranged in the region. The air vent is configured to be directed adjacent to a seated occupant's head and neck.
