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.

First claim

What is claimed is:

1. A climate-controlled seating assembly, comprising:
a cushion having an outer surface, said outer surface comprising a first side for receiving and supporting an occupant and a second side, said second side facing in a generally opposite direction than said first side; a plurality of fluid passages extending through an interior of the cushion, from the first side to the second side of said cushion, wherein said fluid passages are configured to facilitate a transfer of air from the second side to the first side of the cushion; a support member positioned adjacent the second side of the cushion, said support member comprising a front surface configured to contact at least a portion of the second side of the cushion; wherein the support member further comprises a rear surface, said rear surface being generally opposite of the first surface; at least one fluid distribution system positioned along the front surface of the support member, wherein said at least one fluid distribution system comprises at least one recess within the front surface of the support member; wherein the at least one fluid distribution system does not extend to the rear surface of the support member; wherein the front surface of the support member directly contacts the second side of the cushion member in areas adjacent the at least one recess and along a majority of an interface between the 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 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; and a fluid module in fluid communication with the at least one fluid channel; wherein, when in use, the fluid module is configured to deliver air into said at least one fluid channel and to at least some of the fluid passages, toward the first side of the cushion; and wherein, when in use, air directed into the at least one fluid channel is configured to be distributed at least partially laterally within said at least one fluid channel.

2. The seating assembly of claim 1 8, wherein the fluid module comprises a fluid transfer device and at least one thermal conditioning device, said at least one thermal conditioning device being configured to selectively heat or cool air.

3. The seating assembly of claim 2 , wherein the at least one thermal conditioning device comprises at least one of a thermoelectric device and a convective heater.

4. The seating assembly of claim 1 8, wherein the fluid module is positioned adjacent the rear surface of the structural support member.

5. The seating assembly of claim 1 8, wherein the fluid module is positioned at least partially within the at least one fluid channel.

6. The seating assembly of claim 1 8, wherein the fluid module is positioned completely within the at least one fluid channel.

7. The seating assembly of claim 1 , wherein the support member comprises a plastic material.

8. The seating assembly of claim 1 , A climate-controlled seating assembly, comprising:
a cushion having an outer surface, said outer surface comprising a first side for receiving and supporting an occupant and a second side, said second side facing in a generally opposite direction than said first side;
a plurality of fluid passages extending through an interior of the cushion, from the first side to the second side of said cushion, wherein said fluid passages are configured to facilitate a transfer of air from the second side to the first side of the cushion;
a structural support member positioned adjacent the second side of the cushion, said structural support member comprising a front surface facing the second side of the cushion and configured to contact at least a portion of the second side of the cushion;
wherein the structural support member further comprises a rear surface, said rear surface being generally opposite of the front surface;
at least one fluid distribution system positioned along the front surface of the structural support member, wherein said at least one fluid distribution system comprises at least one recess within the front surface of structural support member;
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:
a cushion having an outer surface, said outer surface comprising a first side for supporting an occupant and a second side, said second side facing in a generally opposite direction than said first side; wherein at least a portion of the cushion is generally air permeable so as to permit air to pass from the second side to the first side of said cushion; a support member positioned adjacent the second side of the cushion, said support member comprising a front surface configured to contact at least a portion of the second side of the cushion; wherein the support member further comprises a rear surface, said rear surface being generally opposite of the first surface; at least one fluid distribution system formed along the front surface of the support member, wherein said at least one fluid distribution system comprises at least one recess within said front surface; wherein the support member comprises a first uniform thickness along the at least one recess and a second uniform thickness along a remaining area of the support member, wherein the second uniform thickness is greater than the first uniform thickness; wherein the at least one recess of the at least one fluid distribution system and the adjacent second side of the cushion together form at least one fluid channel when the support member is secured to said cushion wherein, when in use, air from a fluid module in fluid communication with the at least one fluid channel is configured to be delivered into said at least one fluid channel and at least partially through an air permeable portion of the cushion, toward the first side of the cushion; and wherein, when in use, air directed into the at least one fluid channel is configured to be distributed at least partially laterally within said at least one fluid channel.

14. The seating assembly of claim 13 , wherein the seating assembly additionally compri
