Abstract
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.
