Abstract

A tire carrier assembly for storing a spare tire on a vehicle which includes a carrier adapted for supporting the spare tire and a winch operatively connected to the carrier to raise and lower the carrier between a stowed position wherein the carrier is inaccessible and a deployed position wherein the carrier is accessible. The winch has a flexible member secured to the carrier and one of an electric motor and a manual device which selectively raises and lowers the carrier between the stowed and deployed positions. A sensor is activated when the carrier is in the stowed position. A warning indicator is operably connected to the sensor so that the warning indicator is activated and provides the operator with a warning when the carrier is out of the stowed position and the sensor is not activated.

Claims

1. A tire carrier assembly for storing a spare tire on a vehicle, said tire carrier assembly comprising, in combination:

a carrier adapted for supporting the spare tire;

a winch operatively connected to the carrier to raise and lower the carrier between a stowed position wherein the carrier is inaccessible and a deployed position wherein the carrier is accessible;

a sensor located to be activated when the carrier is in the stowed position;

a warning indicator operably connected to the sensor so that the warning indicator is activated when the carrier is out of the stowed position and the sensor is not activated;

wherein the winch includes a flexible member connected to the carrier to raise and lower the carrier;

a monitoring device adjacent the flexible member to measure tension in the flexible member; and

a control module operably connected to the monitoring device to monitor a tension force level in the flexible member.

2. The tire carrier assembly according to claim 1, wherein the winch includes a rotatable shaft, a reel rotatable with the shaft, and wherein the elongate flexible member extends between the reel and the carrier so that the flexible member is wound and unwound upon the reel respectively when the shaft rotates in opposite directions.

3. The tire carrier assembly according to claim 2, wherein the actuation member is an electric motor operably connected to the shaft for operating the winch to raise and lower the carrier.

4. The tire carrier assembly according to claim 2, wherein the shaft of the winch does not have an electric motor connected thereto so that the shaft must be manually rotated to operate the winch and raise and lower the carrier, and the actuation member is a manual device operably connected to the shaft for manually operating the winch to raise and lower the carrier.

5. The tire carrier assembly according to claim 1, wherein the monitoring device engages and deflects the flexible member and determine the tension force level in the flexible member.

6. The tire carrier assembly according to claim 1, wherein the monitoring device includes a switch portion and a biased probe engaging the flexible member the flexible member.

7. The tire carrier assembly according to claim 1, wherein the sensor is a limit switch.

8. The tire carrier assembly according to claim 1, wherein the sensor is a proximity switch.

9. The tire carrier assembly according to claim 1, wherein the sensor is a force switch.

10. The tire carrier assembly according to claim 1, wherein the sensor is a pressure sensor.

11. The tire carrier assembly according to claim 1, wherein the sensor engages a portion of the spare tire to indicate when the carrier is in the stowed position.

12. The tire carrier assembly according to claim 1, wherein the sensor engages a portion of the carrier to indicate when the carrier is in the stowed position.

13. The tire carrier assembly according to claim 1, wherein the warning indicator is a warning lamp.
