A vehicle seat and seating system is disclosed that includes a seat portion (e.g., seat bottom, seat back) defining a cavity with an inlet in fluid communication with a vehicle cabin and an outlet in fluid communication with an ambient environment. The cavity with the inlet and outlet provide an exhaust to allow air in the cabin to escape to the ambient environment when the air is pressurized due to, for example, a vehicle door closing. An acoustic seal is provided adjacent the cavity and is configured to seal at least a portion of the passageway to reduce or dampen sound from entering the cabin.

A vehicle seating assembly includes a seating frame. A plurality of cellular supports include multiple base cells and multiple support cells. The multiple support cells are disposed directly above and include a different air pressure than the base cells. A diaphragm is proximate the base cells and the support cells. An air passage is defined through the diaphragm between adjacent cellular supports. An open air distribution layer extends over the cellular supports. A breathable coverstock extends over the distribution layer.

Providing a seat pad that can provide good sitting comfortability with bonding between a ventilation member and an expanded resin foam included in the seat pad ensured. A seat pad 10 including a ventilation member 20 having a function that lets air through to/from an outside, the seat pad 10 being formed by integral expansion molding of an expandable resin material M with the ventilation member 20 introduced therein, includes a covering member 30 that covers at least a part of the ventilation member 20 at an interface between the ventilation member 20 and the expandable resin material M, and the covering member 30 includes an impregnation inhibiting material having a function that inhibits infiltration of the expandable resin material M, the function being at least higher than that of the ventilation member 20.

In a motor-vehicle seat a padding body of a cushion and/or backrest has a passage for air coming from an air conditioning system of the motor-vehicle. This passage includes a closed cavity defined between a lowered surface formed in an outer surface of the padding body and the seat cover. At least part of the closed cavity is separated from the cover through a layer of a material substantially impervious to air, configured to exchange heat by thermal conduction, through the cover with a body of an occupant.

A foam part (5, 105, 205, 305), in particular for a vehicle seat, includes several comfort tubes (50, 150, 250, 350) facing a user. Several of the comfort tubes (50, 150, 250, 350) respectively comprise a hole (55, 155, 255, 355, 60, 160, 260, 360) or several holes (55, 155, 255, 355, 60, 160, 260, 360). At least one of the holes (55, 155, 255, 355, 60, 160, 260, 360) is embodied as a blind hole (60, 160, 260, 360).

A seat including an exterior seat surface. The exterior seat surface is movable inward and outward relative to an interior of the seat. A flexible material overlays the exterior seat surface. The flexible material is lockable to restrict movement of the flexible material towards the exterior seat surface. Movement of the exterior seat surface into the seat defines a gap between the exterior seat surface and the flexible material to permit air to circulate between the exterior seat surface and the flexible material to cool an occupant of the seat.

An armrest includes an upper support section having one or more ventilation and drainage apertures that couple an upper surface of the upper support section to a lower portion of the armrest to facilitate airflow and drainage between the upper surface of the upper support section and the lower portion of the armrest. The armrest also includes one or more control implements and an arm pad removably coupled to the upper support section. The arm pad includes one or more pad apertures formed therein that communicate with the ventilation and drainage apertures to allow ventilation and drainage between an upper surface of the arm pad and the lower portion of the armrest.

A tubular lower mold partitioning wall is erected on a lower mold, and a three-dimensional mesh-like body is disposed with a part of a side face exposed with respect to the lower mold partitioning wall. When a pad main body is molded by foaming a liquid raw material, the mesh-like body is penetrated through the pad main body in a thickness direction. Since the mesh-like body is disposed with a part of the side face exposed with respect to the lower mold partitioning wall, the liquid raw material is hardened between the fibers on the side face of the mesh-like body, and the side face is attached to the pad main body. Therefore, it is possible that the mesh-like body is not easily displaced with respect to the pad main body while suppressing a sweaty feeling.

A cushion cover for a ventilation seat includes: a first adhesive layer including an upper surface coupled to a lower surface of a cushion part of the ventilation seat, the lower surface of the cushion provided with an air flow channel; a non-permeable layer made of a non-permeable material and including an upper surface coupled to a lower surface of the first adhesive layer to block the air flow channel of the lower surface of the cushion part from outside; and a protective layer coupled to a lower surface of the non-permeable layer to direct friction between the non-permeable layer and a seat structure.

A three-dimensional mesh-like body is disposed on a molding face of a lower mold onto which a liquid raw material of flexible foam is poured. An upper mold is laid over the lower mold to form a cavity, a projection projected on the upper mold toward the cavity is contacted with the three-dimensional mesh-like body, and the three-dimensional mesh-like body is fixed. The three-dimensional mesh-like body is attached and fixed to a front surface of a pad main body, so that the three-dimensional mesh-like body can be prevented from being displaced with respect to the pad main body. Moreover, the position of the three-dimensional mesh-like body can be prevented from being displaced in the process of foaming the liquid raw material because of the projection, and a vent hole can be formed on the pad main body. As a result, a sweaty feeling can be suppressed.
