A headrest ventilation assembly is configured to secure to a headrest of a seat assembly, and includes an air conduit including one or more air inlets and one or more air outlets, and an air filter disposed within the air conduit between the one or more air inlets and the one or more air outlets. The air filter is configured to remove contaminants from the air that is drawn into the air conduit before being delivered out of the one or more air outlets. The assembly can also include a fan disposed on or within the air conduit. The fan is configured to draw the air into the one or more air inlets and provide airflow to deliver the air out of the one or more air outlets. The assembly can also include one or more ultraviolet (UV) light emitters disposed on or within the air conduit. The UV light emitter(s) are configured to emit UV light into the air to sanitize the air before the air is delivered out of the one or more air outlets.

A vehicle seat is provided with a temperature-control system which is connectable or connected to a temperature-control circuit that conveys a temperature-control medium. Thermal energy from the temperature-control medium conveyed in or to at least one temperature-control heat exchanger of the temperature-control system is deliverable to and/or absorbable from the surroundings. The vehicle seat has at least one flow generation system, in particular a fan system, which generates a gas flow. The at least one flow generation system is controllable by a controller, with the temperature of the gas flow being controllable via at least one temperature-control heat exchanger and/or via an electrically operated temperature-control element.

A vehicle seat includes a temperature-control system which is connectable or connected to a temperature-control circuit that conveys a temperature-control medium. The vehicle seat includes at least one temperature-control heat exchanger by which thermal energy can be delivered to and/or absorbed from the environment using the temperature-control medium. The vehicle seat includes at least one electrically operable or electrically operated temperature-control element which is a heating and/or cooling element.

A seat cushion S1 of a vehicle seat S includes: a pad member 10 including a base pad 11 and an intermediate pad 12 overlapped on the base pad 11; a fan 31 provided so that air passes through the pad member 10; air passage holes 11h and 12h respectively formed in the base pad 11 and the intermediate pad 12; and a pull-in hole provided at a position different from the air passage hole 12h in the intermediate pad 12 and a position of the intermediate pad 12 with respect to the base pad 11 is held in such a manner that a skin pull-in trim cord enters the pull-in hole while the intermediate pad 12 is overlapped on the base pad 11 so that the air passage holes 11h and 12h communicate with each other.

A ventilated molded seat trim cover for a vehicle seat and a ventilated vehicle seat having a ventilated molded seat trim cover, comprising a stacked assembly of an upper textile layer, a first adhesive layer, an air permeable polyurethane cellular foam interlayer thermo-moldable at temperatures between about 104° C. and about 127° C., a second adhesive layer, a thermoplastic polyurethane (TPU) film, a third adhesive layer, and a scrim backing layer. The stacked assembly is compression molded in a 3-dimensional mold while at least a portion of the foam interlayer is heated to a temperature between about 104° C. and about 127° C. to form the ventilated molded seat trim cover. The TPU film prevents airflow passing through a bottom surface of the seat trim cover. Airflow in the foam interlayer can pass through the upper textile layer.

A seat for a passenger compartment, for example a vehicle passenger compartment. The seat has a backrest that includes a heating device for heating the space behind the backrest. The heating device includes, from front to back of the backrest, an insulating layer which is a foam, a heating layer, and an outer layer which forms the back of the backrest. The assembly of the insulating layer and the heating layer is achieved by compression on at least their peripheries.

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 vehicle seat may include a seat body having a seat base and a backrest arranged to extend upward from the base. The seat body may include an exterior covering. The vehicle seat may further include a comfort system disposed within the seat body and including a heating track configured to emit heat.

Provided is vehicle seat with a seat cushion and a seat back, the vehicle seat comprising: a duct disposed astride the seat cushion and the seat back, and configured to connect an air passage and a blower, the air passage being formed in the seat cushion and the seat back; and a side frame cover configured to cover part of the duct. The duct includes a first duct member and a second duct member connected to the first duct member. The side frame cover is configured to cover at least part of a first connected section that is a section at which the first duct member and the second duct member are connected.

A vehicle seat includes: a chamber in which at least a seat-front-surface side is covered with a pad and which circulates the air blown from a front surface of a seat through the pad; a fan configured to send air into the chamber; and a support body which supports the chamber so as to be able to sink in an acting direction of a load applied to the surface of the seat. The chamber includes a first region and a second region, and the first region and the second region are configured to allow subduction of the chamber independently of each other.
