Abstract

A climate controlled seat assembly includes a seat cushion that has an outer surface with a first side for supporting an occupant in a seated position and a second side, which generally faces in an opposite direction than the first side. An air passage extends from the first side to the second side of the seat cushion. A support member has a first side that is configured to provide support to the seat cushion and a second side. the first side and the second side of the support member generally face in opposite directions. A distribution passage is in communication with the air passage and is formed at least in part by a recess formed at least in part in one of the first side of the support member and the second side of the seat cushion.

wherein the at least one fluid distribution system does not extend to the rear surface of the structural support member;

wherein the front surface of the structural support member directly contacts the second side of the cushion member in areas of the second side adjacent the at least one recess and along a majority of an interface between structural support member and the cushion member;

wherein the at least one recess of the at least one fluid distribution system forms at least one fluid channel when the structural support member is secured to the cushion, said at least one fluid channel being in fluid communication with at least one of the fluid passages of the cushion;

a fluid module in fluid communication with the at least one fluid channel;

wherein the at least one fluid channel extends at least partially laterally along the second side of the cushion; and

wherein the structural support member comprises a metallic material.

9. The seating assembly of claim 1 8, wherein the seating assembly comprises a seat.

10. The seating assembly of claim 1 8, wherein the seating assembly comprises a bed.

11. The seating assembly of claim 1, wherein the at least one fluid channel does not extend along an entire portion or substantially an entire portion of the second side of the cushion.

12. The seating assembly of claim 1 8, wherein the at least one fluid channel comprises a U-shape, V-shape or semi-circular shape.

13. A climate-controlled seating assembly, comprising:
