First Claim
Patent Images
1. A ventilated seat, comprising:
- an insert located between a cushion and an air permeable seat cover, the insert comprising;
a valve sheet including at least a valve layer, wherein the valve layer includes one or more discontinuities extending through the thickness of the valve sheet to form one or more valves wherein upon application of suitable force the one or more discontinuities are configured to change shape to form an opening extending through the valve layer for allowing fluid flow therethrough and upon removal of said force the one or more discontinuities return to an original shape to close the opening, and wherein the discontinuities formed by the valve sheet comprises crosses formed on a surface of the valve sheet which extend through the thickness of the cross section of the valve sheet;
a heater layer; and
one or more spacers to provide an open space within the insert.

Abstract
In one aspect, the present invention provides a ventilated seat with a valve sheet having one or more valve assemblies. The valve sheet maybe on a frame of the seat. The valve assemblies open in response to a force such as a force applied by an individual occupying the seat. In another aspect, the present invention provides a method of thermally regulating a seat by occupying a seat with a valve sheet. By occupying the seat one or more valves assemblies open air moving though the open valve assemblies thermally regulates the seat.
