The present invention is directed towards a method of forming a ventilated seat. More specifically, in one aspect, the present invention is directed towards providing an insert in fluid communications with an air mover and a seating surface, wherein the system optionally includes a thermoelectric device for providing heating or cooling of air flowing through the insert.

Method for ventilating a seat

The present invention relates to a ventilated seat having an insert with a seat portion, and having a flow control layer with first and second ports, a spacer having an inlay and a main portion, and a first fluid barrier where the inlay is substantially isolated from the main portion by a fluid-tight boundary. The present invention also relates to a ventilated seat having an insert with a seat portion and having a first flow control layer with at least one port, a first and a second spacer, and a fluid barrier comprising at least one port. The present invention also relates to a ventilated seat with an insert having a seat portion and having a flow control layer with a port and a plurality of flow holes in the seat portion, a spacer, a fluid barrier and at least one conduit with a plurality of flow holes located adjacent to the seat portion of the flow control layer. The seat also may include a fan in fluid communication with the spacer and a fluid conditioning device. The present invention also relates to methods of ventilating a seat. The method includes providing a thermoelectric device (TED) and conditioning air with the TED to provide heating or cooling and communicating that conditioned air through an insert with either pushing or pulling the condition air through the insert.

Ventilated seat

A surface-heating element for a curved surface and method of producing a heating element is provided. The heating element includes a continuous, planar conductor arranged along a longitudinal axis including a plurality of turns connected by regions being generally transverse to the longitudinal axis. The conductor including end portions each having a terminal for receiving electrical current. The heating element also includes a film applied to one side of the conductor and configured to substantially follow an outer contour of the conductor. The film and the conductor form a continuous web generally centered about the longitudinal axis, and at least one turn connecting two generally transverse regions extends beyond the continuous web. The heating element may also include an adhesive layer on the other side of the heating element sealingly engaging the film.
