Patent ID: RE41765

Claim:
Apparatus for selectively varying the environmental temperature of a vehicle seat comprising: a support member in the seat formed from a resilient material, wherein the support member includes: an integral air flow channel that extends through the support member from a bottom surface to a top surface of the support member, the air flow channel having an inlet at the bottom surface of the support member for receiving temperature conditioned air therein, and further having an outlet at the top surface of the support member for dispensing temperature conditioned air therefrom; and at least one air subchannel integral with and extending along a top surface of the support member, wherein the air subchannel is connected with the outlet of the air flow channel; and a porous member which substantially covers the top surface area of the support member, the porous member having an interface with the air subchannel; and a seat cover that substantially encapsulates the porous member to the support member.
