Abstract

A seating construction with a plurality of plenums into which is received temperature conditioned air. The air passes through the seat via a plurality of channels formed in the foam of the seat cushion. The air then migrates through a reticulated foam layer that is itself covered with an air permeable layer of material. The reticulated foam and stitching of the seat fabric facilitate diffusion of the air from the foam channel conduits. The air then convectively circulates against and near the occupant of the seat to facilitate climate control around the occupant.

Description

[0001] Related Applications: The present application is a continuation of prior application Ser. No. 09 / 239,054, filed Jan. 27, 1999.BACKGROUND OF THE INVENTION

[0002] 1. Field of the Invention

[0003] The invention provides a method and apparatus for climate control of an individualized occupant seat In the practice of this invention, there is a method and apparatus for providing conditioned air to a vehicle seat's occupant. Conditioned air is obtained from a central source in the vehicle and is channeled through the seat. The air is then separated into a plurality of smaller subchannels via a manifold. The air is then further divided up, i.e., diffused, through a layer of reticulated foam. This reticulated foam takes the place of the upholstery backing foam that is normally used in a vehicle seat. The air passes through the foam, both perpendicular to, as well as parallel with, the seat cushion surface. The air, in exiting the reticulated foam, is directed through the seat covering. The...
