A vehicle seat including: a seat cushion on which a passenger is able to be seated; a seat back that is attached to a rear end of the seat cushion; and an electric component that is provided to at least one of the seat cushion and the seat back, wherein a fastening member is provided to the rear end of the seat cushion or a lower end of the seat back, an electric wire for supplying an electric power to the electric component is fastened to the rear end of the seat cushion or the lower end of the seat back by the fastening member, and one of the seat cushion and the seat back to which the fastening member is provided includes a contact regulation portion that is located behind the fastening member.

A seat air conditioner includes a housing disposed in a space formed below a seating portion of a seat and above a cabin floor surface inside a cabin. The housing houses: a compressor that compresses and discharges a refrigerant; a condenser that dissipates heat from the refrigerant discharged from the compressor; a decompressor that decompresses the refrigerant flowing out of the condenser; an evaporator that evaporates the refrigerant decompressed by the decompressor; and an air blower that blows air to be heat-exchanged with the refrigerant. The air blower is capable of drawing the air through a ventilation opening formed on an upper face of the housing.

A seat element having a cover and padding configured to serve as support for a user, and having a ventilation and thermal control system that includes a thermoelectric module, a blower, and a conduit delimiting a passage for air connecting the blower and the thermoelectric module. The ventilation and thermal control system is configured for passing a flow of air coming from the cover towards the blower, and the thermoelectric module is configured for cooling and/or heating the airflow.

An occupant support includes a seat and a seat cover. The seat is adapted to support an occupant resting thereon. The seat cover is coupled to the seat and arranged to lie between the occupant and the seat.

A heater control system includes a heater driver, a current sensor, a slope calculator, and a mode selector. The heater driver is configured to control current to a heater. The current sensor is configured to sense current supplied to the heater. The slope calculator is configured to calculate a slope of the current supplied to the heater. The mode selector is configured to adjust current supplied to the heater by the heated driver based on the slope of the current.

A humidity-responsive seat control device for a vehicle employs a self-transforming film including a kind of biomaterial configured to operate to be opened through gradual shrinkage thereof when humidity of a seat cover or humidity inside of the seat cover increases while operating to be closed through gradual expansion thereof when the humidity of the seat cover or the humidity inside of the seat cover decreases, thereby being capable of not only achieving smooth air ventilation in an area where a body portion of a seat occupant contacts the seat cover, but also automatically adjusting an amount of air discharged outwards through the self-transforming film in accordance with humidity.

A system and method for entrainment of a user based on bio rhythm of the user. The system includes an analyzing unit and an entraining rhythm generation unit. The analyzing unit receives bio rhythm information of a user, analyzes the bio rhythm information, and sets an entraining target based on an analysis of the bio rhythm information. The entraining rhythm generation unit generates an entraining rhythm based on the entraining target for providing an entrainment experience to the user, and control one or more human sensory inputs to the user based on the entraining rhythm. The bio-rhythm information may be information related to a breathing rate, a heart rate, brain waves, circadian rhythm, body rhythm, emotion, etc. The entrainment experience may be provided either inside or outside a vehicle.

A portable heating pad assembly for on-demand heating of a seat of a vehicle or a stroller includes a housing, which defines an interior space. A battery, which is rechargeable, is positioned in the interior space. A power cord, which is operationally engaged to the battery, is attached to and extends from the housing. A plug of the power cord is engageable to a receptacle of a source of electrical current to charge the battery. A power cable, which is operationally engaged to the battery, is attached to and extends from the housing. A heating pad is operationally engaged to the power cable and can be selectively positioned on a seat of a vehicle and a seating surface of a stroller. The heating pad thus can warm a child seated in the seat of the vehicle or in the stroller.

A heating and cooling device is disclosed comprising at least one integral low voltage heating and cooling source and an efficient flexible heat distribution means having a thermal conductivity of from 375 to 4000 W/mK for distributing the heat and cool across a surface. Further aspects include thermal interface compounds to provide full thermal contact as well as the use of a phase change material to provide a long lasting heating and/or cooling effect without the use of external electrical input. Preferred applications include automotive and furniture seating heating and cooling, along with outdoor garments having distributed heating and cooling effects.

A method of autonomously providing thermal comfort to an occupant in contact with a component includes the step of determining a heat flux between the component and the occupant. A heat flux inversion is determined using the heat flux. The heat flux inversion corresponds to a change in occupant thermal comfort. A thermal conditioning device is controlled based upon the heat flux inversion to maintain a desired heat flux.
