Abstract

There is disclosed a temperature conditioned assembly for use in a component (e.g., a seat or steering wheel) of a transportation vehicle (e.g., an automotive vehicle, a plane, a train or the like). The assembly typically includes one or more conditions such as a heater and/or a ventilation or cooling system. A controller and a temperature sensor are also included in the assembly. Preferably, the controller is programmed to effect an energy output sequence that is based upon the ambient temperature sensed by the temperature sensor.

Claims

1. An assembly for a transportation vehicle, comprising:

a component located within a passenger compartment of the transportation vehicle;

a conditioner configured for providing at least one of heating, cooling or ventilation to the component of the transportation vehicle;

a controller in communication with the conditioner and an energy source, the controller including a temperature sensor integrated therewith, wherein;

i) the controller is located within the compartment of the transportation vehicle non-adjacent to conditioner such that the temperature sensor can measure a temperature of ambient air within the compartment of the transportation vehicle; and

ii) the controller includes programming for, upon activation of the conditioner, effecting a particular energy output sequence from the energy source to the conditioner based upon the temperature of the ambient air at the time of activation.

2. An assembly as in claim 1 wherein the component is selected from a steering wheel or a seat.

3. An assembly as in claim 1 wherein the temperature sensor is located within 2.0 cm of a periphery of the controller.

4. An assembly as in claim 3 wherein the periphery of the controller is defined at least partially by a housing.

5. An assembly as in claim 4 wherein the housing includes an opening to provide fluid communication between the ambient air and the air surrounding the temperature sensor.

6. An assembly as in claim 5 wherein the energy output sequence includes providing a predetermined amount of energy to the conditioner for an initial predetermined amount of time that is based upon the temperature of the ambient air.

7. An assembly as in claim 6 wherein the energy output sequence includes, after the initial amount of time, providing energy to the conditioner at various levels depending upon the temperature of the ambient air sensed at intervals of time.

9. An assembly as in claim 1 wherein the temperature sensor is located within 2.0 cm of a periphery of the controller.

10. An assembly as in claim 9 wherein the periphery of the controller is defined at least partially by a housing.

11. An assembly as in claim 10 wherein the housing includes an opening to provide fluid communication between the ambient air and the air surrounding the temperature sensor.

8. An assembly for an automotive vehicle, comprising:

a component located within a passenger compartment of the automotive vehicle wherein the component is selected from a seat or a steering wheel;

a heater configured for providing heating to the component;

a controller in communication with the heater and an energy source, the controller including a temperature sensor integrated therewith, wherein;

i) the controller is also located within the compartment of the automotive vehicle such that the temperature sensor is non-adjacent to heater such that the temperature sensor can measure a temperature of ambient air within the compartment of the automotive vehicle;

ii) the controller includes programming for, upon activation of the heater, effecting a particular energy output sequence from the energy source to the conditioner based upon the temperature of the ambient air at the time of activation; and

iii) the temperature sensor is integrated with a circuit board of the controller.

12. An assembly as in claim 8 wherein the energy output sequence includes providing a predetermined amount of energy to the conditioner for an initial predetermined amount of time that is based upon the temperature of the ambient air.

13. An assembly as in claim 12 wherein the energy output sequence includes, after the initial amount of time, providing energy to the conditioner at various levels depending upon the temperature of the ambient air sensed at intervals of time.

14. A seat assembly for an automotive vehicle, comprising:

a seat cushion component having a seating surface, the seat cushion component selected from a backrest cushion component or a base cushion component;

a heater with at least one heating element configured for providing heat to or adjacent the seating surface of the seat cushion component;

a controller in communication with the heater and an energy source, the controller including a temperature sensor wherein;

i) the controller is located within a cabin of the automotive vehicle such that the temperature sensor is non-adjacent to the heater such that the temperature sensor can measure a temperature of ambient air within the cabin of the automotive vehicle; and

ii) the controller includes programming for, upon activation of the heater, effecting a particular energy output sequence from the energy source to the heater based upon the temperature of the ambient air at the time of activation.

15. An assembly as in claim 14 wherein the heater overlays a cushion of the seat cushion component, the heater including a substrate and at least one heating element.

16. An assembly as in claim 14 wherein the temperature sensor is located within 2.0 cm of a periphery of the controller.

17. An assembly as in claim 16 wherein the periphery of the controller is defined at least partially by a housing.

18. An assembly as in claim 17 wherein the housing includes an opening to provide fluid communication between the ambient air and the air surrounding the temperature sensor.

19. An assembly as in claim 14 wherein the energy output sequence includes providing a predetermined amount of energy to the conditioner for an initial predetermined amount of time that is based upon the temperature of the ambient air.

20. An assembly as in claim 19 wherein the energy output sequence includes, after the initial amount of time, providing energy to the conditioner at various levels depending upon the temperature of the ambient air sensed at intervals of time.
