The present invention relates to a duct module and a vehicle seat including a duct module. According to an exemplary embodiment of the present invention, the duct module includes a duct, an air intake module and a sterilization module. The duct may have a duct air passage formed therein and include a first rigid portion, a second rigid portion, and a flexible portion disposed between the first rigid portion and the second rigid portion. The air intake module may be connected to the first rigid portion of the duct and guide external air into the duct air passage. Further, the sterilization module may be disposed in the duct to emit sterilization light into the duct air passage. The duct air passage may be formed as an internal space of the first rigid portion, the second rigid portion and the flexible portion.

A seat air-conditioner is applied for a seat on which an occupant is seated. The seat air-conditioner includes a blower configured to suck air through a supporting surface of the seat that supports the occupant, and an introducing passage through which the air is introduced from the supporting surface to the blower. The seat includes a seat cushion supporting a lower body of the occupant and a seat back supporting an upper body of the occupant. The blower is disposed in the seat back such that airflow generated by the blower flows more through the seat back than through the seat cushion.

There is provided a vehicle seat (car seat) comprising a seat cushion pad (seat body) having an air passage connected to an outlet port (114), and a blower having an inlet port (113) and configured to feed air taken in through the inlet port (113) to the air passage. The blower (100) is located on the lower side of the seat cushion pad (seat body) that is opposite to an occupant's side on which an occupant is to be seated, and the inlet port (113) is directed upward that is a direction toward the seat cushion pad (seat body).

A seat support is provided with a plurality of layers of a non-foam material to mount to a seat frame and to support an occupant upon the seat frame. The plurality of layers is stacked upon each other, and each of the plurality of stacked layers has a generally uniform thickness.

A seat includes comprising: a seat bottom and a seat back operatively engaging the seat bottom. At, least one of the seat back and the seat bottom has an air impermeable outer trim layer covering at least a portion of an outer surface. The air impermeable outer trim layer includes perforations extending therethrough. The, size, spacing, or both of the perforations varies based at least in part on a body pressure map, and the perforations are configured to allow airflow therethrough directed toward an occupant of the seat.

Provided is a conveyance seat in which a duct connected to a fan can be compactly disposed, and the fan is provided in a pan-frame-type seat cushion. The vehicle seat includes a seat cushion (S2) and a blower (48) provided in the seat cushion (S2). The seat cushion (S2) is provided with a plate-shaped pan frame (42). The blower (48) is provided below the pan frame (42), a duct (49) is connected to the blower (48), and an opening (42a) through which the duct (49) extends is formed in the pan frame (42).

Heating and cooling device for a vehicle seat with separating material (2) that forms at least a portion of an air-distribution chamber (1), with an upper-side layer (4) covering the separating material (2) on its upper side, with a lower-side layer (5) of separating material (2) on the underside opposite from the upper-side layer (4) that is essentially airtight whereby the upper-side layer (4) and the lower-side layer (5) are connected together about the outer circumference of the separating materials (2). An air-inlet aperture (6) is provided to the air-distribution chamber (1) and air-outlet apertures (10) are provided in the upper-side layer (4) to remove air from the air-distribution chamber (1). The upper-side layer (4) and the lower-side layer (5) are connected at least about their outer circumference by a box-shaped insert (3).

The main cushion (3) of an automobile seat (e.g. the seat pan cushion, or a backrest cushion) is provided with a shield (2). The shield surrounds at least part of the lateral sides of the main cushion and is formed of a less compressible (i.e. harder) foam than the main cushion, such that when the seat is upholstered, creases in the upholstery are reduced/prevented and gapping is avoided.

A vehicle seat assembly comprises a seat bottom having a bottom cushion, a seat back coupled to the seat bottom with the seat back having a back cushion, and at least one of the bottom cushion and the back cushion having a passage. The assembly further includes a flow control layer coupled to the cushion having the passage with the flow control layer defining a first support area having a first plurality of slits and a second support area, adjacent to the first support area, having a second plurality of slits. Each slit defines a width that is moveable between a restricted position and a free-flowing position. The width of the first slits can move to the free-flowing position while the width of the second slits remains in the restricted position when the first support area receives a first load for flowing air through the first slits and the passage.

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.
