Abstract: In a preferred embodiment there is disclosed a vehicular seat element comprising a foam substrate, the foam substrate comprising an A-surface for contact by an occupant and a B-surface opposed to the A-surface, a central portion of the A-surface have a first surface area and comprising a plurality of channels, the central portion of the A-surface comprising an occupant contact portion having a second surface area, wherein the first surface area is greater than the second surface area, a plurality of apertures disposed in the plurality of channels, each aperture interconnecting the A-surface and the B-surface of the foam substrate. The plurality of channels acts a distribution manifold for air to be moved laterally with respect to the A-surface of the foam pad and also through the holes in the seat pad to allow for circulation of air. In other words, the through holes in the foam provide a pass for air to flow from the B-surface of the foam pad to the A-surface of the foam pad, and vice versa. This air flow is further promoted by compressing and decompressing of the foam by the mass of the occupant while the vehicle is in motion. This compression and decompression of the foam creates a so-called bellows effect to push or pull air through the vehicular seat. Ideally, the series of channels molded in the A-surface of the foam pad form a manifold that enhances air distribution by providing multiple paths for the air flow around (not just beneath) the occupant and through the seat.

Abstract translation: 在一个优选实施例中，公开了一种车辆座椅元件，其包括泡沫衬底，所述泡沫衬底包括用于与乘员接触的A表面和与所述A表面相对的B表面，所述A表面的中心部分具有 第一表面区域并且包括多个通道，所述A表面的中心部分包​​括具有第二表面区域的乘员接触部分，其中所述第一表面区域大于所述第二表面区域，设置在所述第二表面区域中的多个孔 多个通道，每个孔互连泡沫基材的A表面和B表面。 多个通道作用于空气相对于泡沫垫的A表面横向移动并且还通过座垫的孔以允许空气循环的分配歧管。 换句话说，泡沫中的通孔提供空气从泡沫垫的B表面流动到泡沫垫的A表面的通过，反之亦然。 通过在车辆运动时由乘员的质量压缩和减压泡沫，进一步促进了这种气流。 泡沫的这种压缩和减压产生了所谓的波纹管效应，以推动或拉动空气通过车辆座椅。 理想地，模制在泡沫垫的A表面中的一系列通道形成歧管，其通过为乘员和座椅周围的空气流（不仅在下方）提供多条路径来增强空气分布。
