The present disclosure describes vehicle seats having integral components for use with ventilation, air conditioning, and/or heating systems. Air ducting can be incorporated into the seat base and the seat back. Further, air can be directed through a rear-facing outlet vent in the seat back, providing improved ventilation, air conditioning, and/or heating for rear passengers of a vehicle.

A system for heating and cooling a passenger seat utilizing a single unit for producing hot and cold conditioned air. The system includes a source of pressurized air, a vortex tube coupled to the source of pressurized air for producing hot and cold air streams, a duct network coupled to the vortex tube through a valve assembly, and a controller controlling passage of the flow of hot and cold air streams through the manifold assembly based on passenger selection. Conditioned air flow can be dispersed into a cushion assembly such as an interior of a spacer mesh component of the cushion assembly.

A ventilation device for the inside of a motor vehicle, having at least one air outflow element and at least one associated directional element. The at least one air outflow element is provided in a functional arrangement with an air channel element. The air channel element represents the connection to a supply device as part of an air conditioning system. At least one light element is also provided. The arrangement of the at least one directional element and the at least one air outflow element work together so that the ventilation device can be continuously adjusted at least between two inside ventilation conditions. The at least two ventilation conditions respectively differ at least by means of a direction of outflowing air directed directly into the inside and directed indirectly along a roof liner designed for this reason in relation to a seat region of the motor vehicle.

The invention relates to a sensor module (1), comprising: at least a first sensor (10) that is designed to measure relative humidity and/or temperature, wherein the sensor module (1) is configured to be mounted in an automotive seat (2), which automotive seat (2) comprises a seat cover region (200) forming an outer surface (200a) of the seat that faces a passenger (P) sitting on the automotive seat (2), wherein the sensor module (1) is configured to be mounted such in said automotive seat (2) that it is spaced apart from said seat cover region (200). Further, the invention relates to an automotive seat (2) comprising such a sensor module (1).

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.

The present invention provides a method and system for cooling a seat 14 surface, comprising at least one cushion, plurality of flexible metallic heat exchangers and optionally a cushioning layer. The metal heat exchangers are thin flexible metal sheets 18a, 18b with high thermal conductivity and a preferable thickness in the range of 0.05 mm and 10 mm. These are incorporated in the cushion, wherein the conduit is bonded, soldered or brazed to thin flexible metal sheet 18a, 18b acting as continued or intermittent conduit, with fluid, for cooling the metallic heat exchangers. The present system allows lowering of the total temperature difference improving the coefficient of performance of the refrigeration system that supplies the cooled fluid, leading to a smaller, lighter cold water supply system that also consumes less power and performs direct cooling of an occupant's body.

The present disclosure relates to an air conditioning device for a vehicle seat; can include a seat duct formed on a seat of a vehicle, a seat air conditioning unit formed on a lower frame on which the seat is mounted, and a separation space interposed between the seat and the lower frame; and can be formed so that the air is discharged from the air conditioning unit into the separation space, and the air of the separation space is supplied to the seat duct. As a result, it is possible to enhance the mobility of the seat, and to prevent noise and vibration due to driving parts from being delivered to a passenger.

Systems and methods for managing auto start of a vehicle during an auto-stop condition may include determining an operational status of a vehicle climate control system; receiving a target air outlet temperature from the vehicle climate control system; receiving data indicating a state of a heated seat of the vehicle; and inhibiting a start-vehicle command to restart the vehicle because of a cabin heating requirement when the data indicates that the heated seat of the vehicle is activated.

A seat having a heating, ventilation, and air conditioning (HVAC) unit attached thereto includes a base, an aperture, and an activation point. The base has at least one channel therein. The at least one channel receives airflow from the HVAC unit. The aperture is disposed in a surface of the base and in fluid communication with the at least one channel. The activation point provides selective communication through the aperture.

A vehicle seating assembly includes a cushion and a trim layer. A permeable heater is disposed between the cushion and the trim layer. An air mover is in fluid communication with the permeable heater. The permeable heater and the air mover are operable to respectively heat or cool a seating surface.
