A portable collapsible chair may include a frame that may be collapsed to enable a user to carry or store the chair and that may be expanded to form a chair on which the user may sit. The chair may further include a backrest coupled to the frame, a seat coupled to the frame, and one or more heat exchangers. The chair may also include a control circuit coupled to the one or more heat exchangers. The control circuit may provide a first signal to at least some of the one or more heat exchangers to warm the chair in a warming mode or may provide a second signal to at least some of the one or more heat exchangers to cool the chair in a cooling mode.

This disclosure is directed to improved chair assemblies that can be integrated with various technologies, including heating, massaging technologies, cooling, and other technologies. Various portions of the chair assemblies include attachment structures that permit electronic assemblies to be attached and removed from the chair assemblies. The electronic assemblies can include electronics that facilitate heat therapy, massage therapy, and/or cooling therapy functions.

Radiant furniture made of a concrete mix includes one or more heating elements or hot water supplied hydronic tubing that provide comfortable radiant heat. Radiant furniture for sitting includes a radiant seating panel with a bottom cushion overlying the radiant seating panel that provides a heated seating surface for the radiant furniture. A back cushion or a portion of a back cushion can be moved from a first position for sitting to a second position overlying the bottom cushion. A controller senses the temperature of the radiant seating panel and the ambient temperature, then applies power to one or more heating elements in the furniture according to programmed temperature thresholds to provide comfortable radiant heat from the furniture.

A seating unit includes a seat back having a front side and a back side, and a seat bottom having a top side and an underside. A first heating element of the seating unit, attached to the back side of the seat back, can be configured to deliver first heating through the seat back to a user while seated in the seating unit when electrically powered. A second heating element of the seating unit, attached to the underside of the seat bottom, can be configured to deliver second heating through the seat bottom to the user while seated in the seating unit when electrically powered. The seating unit can further include circuitry configured to facilitate delivery of power to the first heating element and the second heating element.

A posture correcting chair having a back rest assembly providing mounting attachments for a head or neck rest, a lumbar support, at least one arm rest, and a posture retainer and supported by a seat assembly. The headrest, lumbar, seat and back support all adjust to allow a user to distribute their weight about a greater number of surfaces for adaptive comfort. A posture retainer affixed to the back rest assembly dynamically adjusts to the contour of a user's body based on force and pressure created while seated to provide active posture correction for a user to prevent slumping or slouching. A knee rest assembly is attached to rail system on a lower end of chair the base platform to provide additional support surfaces. The seat and knee rest assembly include heating, cooling or vibrating or massaging.

A temperature modulation system for a bed, blanket, or other furniture includes a fluid for moderating temperature change, a number of conduit circuits for directing the fluid through respective zones, a control unit including a thermoelectric device for modulating temperature of the fluid, and a pump. Each of the conduit circuits selectively and independently directs fluid through its respective zone in order to produce a temperature within the zone that is independent of the temperature outside the zone. The system also includes an arrangement of one or more zones in an arrangement in which the control unit is programmed to vary the zone temperature over time according to a schedule.

A method of controlling a heat wire of a seat includes: a classification operation of determining whether or not a passenger rides on a vehicle; a calculation operation of calculating a difference with a target temperature by measuring a current temperature of the seat; and a heating operation of heating the heat wire of the seat by differently setting a heating rate so that the temperature of the seat reaches the target temperature up to a heating target time set differently depending on whether or not the passenger rides on the vehicle.

A seating assembly for athletes includes seats having a back and seat portion, a base, an adjustable element, a user interface device, and a controller. The back portion includes a back heating member that provides heat to a user's torso. The seat portion includes a lower limb heating member that provides heat to the user's lower limbs. The base supports each seat. The adjustable element is coupled to the base and one of the seats and adjusts height of the seat. The user interface device receives an input regarding a desired temperature of the back heating member and the lower limb heating member. The controller receives the input and adjusts an operation of the back heating member and the lower limb heating member to achieve the desired temperature. The user interface device receives a second input to adjust the a height of the seat relative to the floor surface.

The present disclosure discloses a ventilation management system for outdoor products, a sleeping bag, and a chair. The ventilation management system for outdoor products comprises a ventilation chamber, a temperature adjustment device, and a mobile power supply. The ventilation chamber is flexible and integrally arranged on the outdoor products, and a side of the ventilation chamber configured to face a human body comprises a plurality of air outlets. The temperature adjustment device comprises a fan and a control module, and the temperature adjustment device is electrically connected to the mobile power supply. The temperature adjustment device is configured to supply cool or warm air to the ventilation chamber, and the cool or warm air is configured to be blown onto the human body via the plurality of air outlets after entering the ventilation chamber. Each of the sleeping bag and the chair comprises the ventilation management system.

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.
