Ventilation system for seat

A climate controlled wheelchair assembly comprising:

• a chamber, wherein the chamber is enclosed to define an interior space, the chamber formed by a fluid impermeable layer, the chamber having a top side, a bottom side, and a peripheral edge between the top side and the bottom side, the top side of the chamber comprising a plurality of openings;
• a support structure positioned within the chamber, said support structure being configured to substantially maintain the shape of the chamber and to help permit the passage of fluid within the chamber;
• a fluid module configured to selectively provide fluid to the chamber, said fluid module comprising a fluid transfer device;
• a fluid inlet in fluid communication with both the chamber and the fluid module;
• a fluid distribution layer positioned adjacent to the first side of the fluid impermeable layer;
• a seat covering positioned along the fluid distribution layer, said seat covering comprising an air permeable material;
• wherein the fluid distribution layer is configured to generally distribute fluid exiting from the openings of the fluid impermeable layer toward the seat covering;
• a conduit in fluid communication with the fluid module and the fluid inlet, such that fluid is selectively delivered from the fluid module to the chamber;
• a battery configured to supply electrical power to the fluid module, wherein said battery is rechargeable;
• a support pad positioned adjacent to the second side of the fluid impermeable layer, said support pad comprising a support material;
• wherein the support pad is configured to provide support and comfort to an occupant of the wheelchair assembly;
• wherein the fluid impermeable layer and the fluid distribution layer are configured to selectively direct fluid flow to targeted regions of the wheelchair assembly;
• and
• wherein the fluid from the fluid module exits the chamber through the plurality of openings in the top side of the chamber.
