Benefits of technology

[0014] In one embodiment, the liquid is a glycol mixture with antifungal and antibacterial properties. The liquid has a freeze point less than the expected ambient temperature expected for its service. In one embodiment, the liquid has a freeze point less than zero degrees Fahrenheit. In one embodiment, the system includes a temperature controller that prevents overheating of the liquid, thereby ensuring that the seat occupant is never exposed to a harmful temperature.

Problems solved by technology

Motorcyclists and drivers of vehicles that do not have an enclosed cabin, such as tractors, forklifts, and boats, do not have access to a cabin with an air conditioning system.

Embodiment Construction

[0036] A seat heating and cooling system is disclosed. The system provides temperature conditioning of the seat, that is, the temperature of the seat is selectively raised or lowered. The system is suitable for use on vehicles in which the operator is exposed to the environment or in which the operator is not in an air conditioned environment.

[0037]FIG. 1 pictorially illustrates one embodiment of the seat heating and cooling system 10 adapted for use on a motorcycle. A motorcycle seat 102 has a coil 104 through which a heat transfer liquid is circulated by a pump 106. The liquid is pumped into a heat exchanger 108, which is part of a heat exchanger assembly 110. The heat exchanger assembly 110 includes the heat exchanger 108, a pair of thermoelectric devices 112a and 112b attached to opposite sides of the heat exchanger 108, a pair of heat sinks 114a and 114b, and a pair of fans 116a and 116b. The inboard surface of the thermoelectric devices 112a and 112b are thermally coupled to ...

Abstract

An apparatus for selectively heating and cooling (temperature conditioning) a seat on a vehicle, where the seat is exposed to the environment. A thermoelectric device selectively heats and cools a heat exchanger filled with a liquid. The liquid is forced through a coil in the seat by a pump. The coil transfers heat by conduction through the seat to the seat's occupant. A controller permits selection of the amount of heating or cooling of the liquid. A switch determines the polarity of the voltage applied to the thermoelectric device, which determines whether the liquid is heated or cooled.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] Not Applicable STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT [0002] Not Applicable BACKGROUND OF THE INVENTION [0003] 1. Field of Invention [0004] This invention pertains to a system that selectively heats and cools a seat. More particularly, this invention pertains to a seat heating and cooling system in which the heat transfer fluid is a liquid and the seat is an exposed seat, such as found on a motorcycle, a tractor, or industrial equipment. [0005] 2. Description of the Related Art [0006] Drivers and passengers of automobiles and trucks have access to air conditioning systems within the vehicle and, in many cases, have the luxury of heated and / or cooled seats. Temperature controlled seats provide increased comfort. [0007] The prior art discloses several different design approaches to the problem of providing an inexpensive, effective and long lasting heated and / or cooled seat. One approach, disclosed in U.S. Pat. No...
