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).

A manifold is coupled to a foam core with a primary manifold opening with a blind coupling fixedly positioned adjacent the B-side of the foam core. Front and rear hook members extend from a coupling frame of the blind coupling. Front and rear lips are positioned on opposite sides of a blower opening with a domed framework. The front hook members are positioned relative to the coupling frame to hook the front lip to provide fore and aft positioning of the blind coupling relative to the blower opening. The front hook members are designed to slide laterally along the front lip and to cause the coupling frame to engage the domed framework to provide lateral positioning of the blind coupling relative to the blower opening.

A vehicle seat capable of efficiently utilizing air delivered from an air conditioning device and thereby adjusting the temperature of heat generated by a seat heater is described. A vehicle seat comprises a seat heater between a cushion pad and a surface skin. A heater wire affixed to a seat base material of the seat heater is disposed at a position to partially overlap air passages formed on the cushion pad. Moreover, the heater wire is formed on the seat base material, is disposed at a position to partially overlap a plurality of through-holes having a greater width than the heater wire, and extends while avoiding center portions of the through-holes.

A vehicle seat comprises a seat bottom having a bottom cushion and a seat back coupled to the seat bottom with the seat back having a back cushion. At least one of the bottom cushion and the back cushion defines a passage. The vehicle seat further comprises a blower assembly coupled to one of the seat bottom and the seat back. The blower assembly comprises a housing and a stator, which is coupled to the housing and comprises a plurality of driving coils. The blower assembly further comprises a rotor rotatably coupled to the housing about a rotational axis, with the rotor comprising a plurality of permanent magnets arranged to generate a flux concentrated on the driving coils. The blower assembly further comprises an impeller coupled to the rotor to rotate about the rotational axis to generate a flow of air through the passage.

An air-conditioning system includes a vehicle air-conditioner which uses a target blowing-out temperature as the basis to control an air outlet temperature in a cabin and a seat air-conditioning unit which sucks recirculated air into a seat. The air-conditioning system controls at least the seat air-conditioning air flow per unit time so as to perform seat air-conditioning. The air-conditioning system increases the seat air-conditioning air flow when detecting that the vehicle speed is stopped or idling, calculates a correction amount for the target blowing-out temperature considered neutral in warmness sense level for the increased seat air-conditioning air flow, and uses the correction amount as the basis to correct the target blowing-out temperature.

A vehicle seat according to the present invention includes: a seat back frame constituting a framework of a seat back; a blower disposed in the seat back; a bracket to which the blower is fixed; and a cover member provided on the rear side of the seat back frame. Herein, the bracket is fixed to the cover member with the seat back frame being held between the bracket and the cover member.

A vehicle seat including a seat pad including a flow channel portion, a seat cover covering the seat pad and having breathability, a functional member disposed between the seat pad and the seat cover and having breathability, and a blowing member configured to blow the gas into or out of the seat through the flow channel portion of the seat pad and the seat cover along a flow path, wherein the functional member is integrated with any one of the seat pad and the seat cover with an adhesive portion, which has poorer breathability than the seat cover and the functional member, interposed therebetween, and wherein the adhesive portion includes a passage portion through which the gas is configured to pass, and the passage portion is disposed in the flow path of the gas.

A seat air conditioning system includes: a seat pad that constitute a seat on which a user is seated and that is resiliently deformed to support the user on a surface-side of the seat pad, the seat pad including ventilation passages that open respectively on the surface-side; a surface cover that has air permeability and is disposed to cover the surface-side of the seat pad; an air outlet at which airs blown out respectively from the ventilation passages meet; and a blower that includes a suction port located on a rear surface-side of the seat pad to be connected to the air outlet and that suctions air from the surface cover-side through the ventilation passages, the air outlet, and the suction port. The air blown out from the air outlet is straightened to flow into the suction port.

A vehicle seat assembly in which an impervious insert (41, 141) including a heating element and having a plurality of channels (42, 142) extending from an aperture (44, 144) positioned on a first side of at least one of a seat cushion (22) and a seat back (124) and in which a ventilation system (60) is coupled to a second side of the at least one of the seat cushion and the seat back for drawing air along the plurality of channels through the aperture and through a hole (30, 130) in the seat cushion or seat back for controlling the temperature of the seat assembly.

Provide are a device for adjusting softness of a vehicle seat, a device for adjusting comfort of a seat, and a vehicle seat. The device for adjusting softness of a vehicle seat has at least one soft inflatable bag that can be integrated in the seat. The soft inflatable bag is connected with at least one air path. The soft inflatable bag is filled with a flexible filler. Gas is charged into or discharged from the soft inflatable bag through the air path to adjust the softness of the surface of the seat. The soft inflatable bag is provided therein with a height limiting structure configured to limit the partial expansion height of the soft inflatable bag when inflated.
