A distribution system for a vehicle seat. The distribution system includes one or more plenums that each have a cap layer, a support layer, and an open space formed between the cap layer and the support layer. The support layer is a generally rigid material and the cap layer is a generally flexible material that is connected to the support layer. The open space includes one or more baffles that assist in directing fluid between a blower connected to the one or more plenums and one or more ventilation holes.

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 seat with a ventilation system that maintains seated person's coolness by blowing air to minimum segments of a seatback and a seat cushion so that seated person's comfort is maintained is provided. Air-blowing means is controlled in air-blowing quantity and air-blowing time periodically by air-blowing control means, and air blowing in each period is set to include a first term T1 in which a predetermined quantity of air is blown and a second term T2 in which the predetermined quantity of air to be blown is gradually reduced.

An air conditioning device for a vehicle seat, the air conditioning device includes: at least one flow generator to generate an air flow; at least one air inlet opening fluidically connected to a flow inlet of the flow generator to draw in air to be temperature-controlled; at least one air outlet opening fluidically connected to a flow outlet of the flow generator to eject the temperature-controlled air; and a temperature-control device configured to control a temperature of the air drawn in through the at least one air inlet opening prior to the air being ejected from the at least one air outlet opening; the at least one air inlet opening and the at least one air outlet opening are arranged next to one another.

A seat comprises a seat cushion pad (20) including an air flow passage (21), and a blower connected to the air flow passage (21). The seat cushion pad (20) comprises a pad body (100), and a cover member (200) disposed on an upper surface of the pad body (100) to form the air flow passage (21) between the pad body (100) and the cover member (200). The cover member (200) comprises a first cover member (210) disposed on the upper surface of the pad body (100), and a second cover member (220) disposed on an upper surface of the first cover member (210). The first cover member (210) is fixed to the pad body (100), and the second cover member (220) is fixed to the first cover member (210) and to the pad body (100).

An infection preventing device includes air barrier forming units that include an air inlet for taking in air from a rear in a front-rear direction, an air purification mechanism for creating clean air by purifying the air taken in from the air inlet, and an air outlet for blowing the clean air toward the front in the front-rear direction, and are capable of blowing out the clean air from the air outlet in the form of layer perpendicular to the left-right direction. The air barrier forming units provided on the seats adjacent in the front-rear direction face in the front-rear direction, and it is configured that air including clean air blown out of the air outlet of the rear air barrier forming unit can be taken in by the air inlet of the front air barrier forming unit.

A thermally conditioned seat includes a seat portion constructed from a first material which includes a seat support structure that has a central support region and adjacent side bolsters laterally spaced apart from one another a width. A recess is provided in the central support region and includes an aperture. A porous material is arranged in the recess against the first material. A second material is arranged against the first material and the porous material. A cover includes an air permeable layer and an aesthetic layer that provides an exterior seating surface. The air permeable layer is arranged against the second material and the aesthetic layer has perforations. A blower is associated with the seat portion and is in fluid communication with the aperture. The blower is configured to supply a fluid through the aperture to the porous material through the recess. The fluid is configured to pass from the porous material to the air permeable layer and out the perforations.

A vehicle seat includes: a seat back having an upper frame; a fan provided in the seat back; a lumbar plate that is provided in the seat back and elastically supports a waist of a seated occupant from a rear side; and a support member that elastically supports the fan in an area at a height between the lumbar plate and the upper frame.

A vehicle seat includes a pad configured to support a body of a seated occupant. The pad has a transverse air passage extending in a direction along a back surface of the pad and a plurality of longitudinal air passages each having one end connecting with the transverse air passage and the other end open to a front surface of the pad. The transverse air passage has a first transverse air passage connecting an air introduction hole from a fan or an air discharge hole to the fan and the longitudinal air passage directly with each other, and a second transverse air passage connecting the air introduction hole or the air discharge hole and the longitudinal air passage with each other via a resistant body having a resistance against an air flow.

A headrest which supports a head portion of a passenger in a vehicle rear collision is attached to an upper portion of a frame of a seatback. A blower to perform ventilation for a passenger's back is arranged at the upper portion of the frame at a position below the headrest. The blower is held at the frame via attaching members, for example. When receiving a large rearward-load from the passenger in the vehicle rear collision, the blower moves rearward relatively to the frame and the headrest according to a rearward move (a rearward swing around an upper frame, particularly) of the attaching member and the like.
