Embodiment Construction

[0018] The vehicle seat of the present invention includes an air diffuser on the surface of the seat cushion. In a particular embodiment, the diffuser is disposed below the trim cover and above the seat cushion. The diffuser is fluidly connected to the temperature regulator by means of at least two conduits, namely at least a first conduit and a second conduit. As part of the thermostat, the blower cooperates with the thermostat to blow air that has been tempered (eg, heated, cooled, dehumidified, etc.) relative to the air diffuser. In certain embodiments, the blower also draws air from the air diffuser.

[0019] Although discussed primarily with respect to the area of ​​the vehicle seat in contact with the occupant's buttocks and thighs (ie, the seat portion), it is also contemplated that the systems and methods are applicable to the backrest portion of the vehicle seat.

[0020] The terms underside and ride side are used for convenience and it should be clear that these te...

Abstract

The present invention includes a seat ventilator with an air diffuser, preferably one with sections. The air diffuser has a spacer material and ventilation holes on its occupant side. A temperature conditioner with a temperature conditioning device (such as a TED) and a blower provide temperature conditioned air. One conduit connects the diffuser to an inlet of the blower, while another duct connects the diffuser and an outlet of the TED. The blower moves air for its inlet to the TED and then from the outlet of the TED to the diffuser. The present invention also includes methods controlling the temperature of a vehicle seat by drawing air from a diffuser in a vehicle seat through at least one conduit and blowing air to the diffuser through at least another conduit, where the blown air has been temperature conditioned. The present invention also includes methods of assembling ventilated vehicle seat that include inserting a nozzle of diffuser into a plug received in the socket of a cushion or threading a tether through a manifold of the temperature conditioner to fluidly connect one or more conduits to the temperature conditioner.
