Spare tire hoist system with composite wheel plate having spring recess
Abstract:
A spare tire hoist may be provided. A retention cable may be used to retain a spare tire against a surface of a motor vehicle. A tensioning spring may be used to tension the retention cable when the spare tire is in a storage position. A wheel plate engages the spare tire and cooperates with the retention cable and the tensioning spring to maintain the spare tire in the storage position. The wheel plate may include an insert portion that engages a center aperture of a wheel rim of the spare tire. A flange portion that substantially surrounds the insert portion and engages a peripheral surface of the wheel rim may also be provided. A reinforcement ring may be included in the wheel plate, substantially coextensive with the insert portion and extending within a substantially hollow region of the flange portion. The reinforcement ring may provide mechanical reinforcement to the wheel plate.
