    • The present invention provides a pneumatic foam cushion for use within a vehicle seat comprising a foam member with a contoured outer surface surrounded by an impermeable layer coextensive therewith. The impermeable layer, which may be a thermoplastic material, permits selective pressurization and depressurization of the foam member, and comprises a first impermeable member having a first contoured shape, and a second impermeable member having either the same shape as the first contoured shape, or a second contoured shape. The first and second impermeable members are matable around the foam member to form the impermeable layer. Preferably, the first and second impermeable members are heat sealed following placement around the foam member. A method of manufacturing a pneumatic foam cushion is also provided.
    • 本发明提供了一种用于车辆座椅内的气动泡沫垫,其包括泡沫构件,所述泡沫构件具有由与其共同延伸的不可渗透层围绕的轮廓外表面。 可以是热塑性材料的不渗透层允许泡沫构件的选择性加压和减压,并且包括具有第一轮廓形状的第一不可渗透构件和具有与第一轮廓形状相同形状的第二不可渗透构件,或 第二个轮廓形状。 第一和第二不可渗透构件可围绕泡沫构件配合以形成不渗透层。 优选地,第一和第二不可渗透构件在放置在泡沫构件周围之前被热密封。 还提供了一种制造气动泡沫垫的方法。
