Abstract

A heating system for a vehicle wing element, wherein the wing element is moveably arranged between an open position and a closed position relative to a vehicle main structure. The heating system includes a heating element at a contact surface between the wing element and the main structure and a control unit for activating the heating element. The system further includes a wing element handle sensor and a wing element latch switch. The switch is operatively connected to the control unit for sending a signal indicative of its state to the control unit. The control unit is arranged to send an activation signal to the heating element when the control unit receives a signal from the wing element handle sensor that the handle is being pulled and a signal from the wing element latch switch that the wing element is closed.

First claim

What is claimed is:

1. A heating system for a vehicle wing element, the wing element being moveably arranged between an open position and a closed position in relation to a vehicle main structure, wherein the heating system comprises:
a heating element arranged at a contact surface between the wing element and the main structure;
a control unit operatively connected to activate the heating element;
a wing element handle sensor operatively connected to the control unit and that sends a signal indicative that a handle of the wing element has been pulled to the control unit; and
a wing element latch switch operatively connected to the control unit and that sends a signal indicative of an open or closed state of the wing element to the control unit,
wherein the control unit activates the heating element upon the control unit receiving both the signal indicative that the handle of the wing element has been pulled and the signal indicative of the open or closed state of the wing element from the wing element latch switch specifying that the wing element is closed.

2. The heating system according to claim 1 , wherein the heating element is a heating coil.

3. The heating system according to claim 1 , wherein the heating system comprises a sealing element arranged at a contact surface between the wing element and the vehicle main structure, and wherein the heating element heats the sealing element.

4. The heating system according to claim 3 , wherein the sealing element comprises resilient rubber.

5. The heating system according to claim 1 , wherein the heating element is an electrical heating element.

6. The heating system according to claim 1 , wherein a temperature sensor is connected to the control unit.

7. The heating system according to claim 1 , wherein the control unit is arranged in the wing element.

8. The heating system according to claim 1 , further comprising a power supply.

9. The heating system according to claim 8 , wherein the power supply is arranged in the wing element.

10. A vehicle comprising the vehicle main structure, the wing element, and the heating system according to claim 1 .

11. The vehicle according to claim 10 , wherein the heating element is arranged around a circumference of the vehicle wing element.
