Abstract
A ventilated vehicle seat includes an imperforate foam air plenum member located in a foam cushion top. The air plenum member is assembled from a molded box-like foam member and an integrally molded cover. The air plenum has an air port for application of positive or negative pressure. The cover has apertures for air to pass into or out of the air plenum member. One preferred embodiment of the air plenum member includes an integrally molded portion that is assembled into an air conduit for said air port. The cover can have various sizes that are larger than the box-like member and can have inner and outer surface conformations to suit various purposes.
Claims24
A ventilated seat that comprises:
- a resilient cushion member made of a foam and having a cushion surface;
- a recess in said cushion surface;
- and air plenum member in said recess and being and air-imperforate foam;
- said air plenum member having an open-topped bottom portion and a cover forming a substantially closed air chamber that cooperates with said resilient cushion member to form a substantially continuous resilient seat surface;
- an air port to said air chamber;
- means for coupling said air chamber with a source of air pressure;
- apertures in said cover and communicating with said air chamber;
- a trim layer covering said resilient seat surface and said cover;
- a positive pressure source or a negative pressure source for passing air through said apertures in said cover.
A ventilated seat that comprises:
- a resilient cushion member made of a foam having a first surface;
- a recess in the first surface of the resilient cushion member;
- a resilient air plenum member made of an air-imperforate foam and comprising an open-topped bottom portion and a cover having a plurality of apertures, the resilient air plenum member disposed in the recess and having at least one air chamber that communicates with the plurality of apertures and a second surface that cooperates with the resilient cushion member to form a substantially continuous resilient seat surface;
- an air port for coupling the air chamber with a source of air pressure adapted to provide at least one of a positive pressure and a negative pressure;
- and
- a trim layer covering the resilient seat surface.
