  • Patent number: 10246920
    Abstract: In at least one implementation, a torsion rod preload device, includes a body, a driver and a retainer. The body may have a base adapted to be connected to a vehicle and at least one stop. The driver is carried by the body for movement relative to the body, and is adapted to engage a torsion rod so that movement of the driver relative to the body increases a torsion force within the torsion rod. The retainer is carried by one or both of the body and the driver, and is movable by the driver as the driver moves relative to the body. The retainer is engageable with the stop to inhibit or prevent movement of the driver when the retainer is engaged with the stop to maintain a desired torsion force in the torsion rod.

  • Patent number: 9902440
    Abstract: A carrier for a spare tire of a vehicle includes a base, a mount, and a locking member. The base is configured to be coupled to the vehicle. The mount is coupled to the base and pivotable relative to the base about a pivot axis. The mount is configured to support the spare tire for common rotation with the mount about the pivot axis. The pivot axis is offset from a central axis of the spare tire when the spare tire is supported by the mount. The locking member is movable between a locked position wherein the locking member engages the mount and the base to prevent relative movement therebetween, and an unlocked position wherein the mount is pivotable relative to the base.

  • Patent number: 9115524
    Abstract: A closure dampening bumper includes a base, a pair of guide walls extending from the base, and a plurality of beams extending from outer surfaces of the guide walls. The base is operable to define a stop-bumper for a moving structure, such as a gooseneck. The guide walls extend from the base and have respective inner and outer surfaces. The inner surfaces taper outward from one another. The distance between the inner surfaces increases from the base to respective distal ends of the guide walls. The guide walls are operable to receive the moving structure between the inner surfaces. The guide walls guide the moving structure to the base. The beams extend from the outer surfaces of the pair of guide walls. The beams elastically deform to dampen the energy associated with the moving structure during passage between the inner surfaces.

  • Patent number: 8708394
    Abstract: A vehicle may include a body, a closure member, a hinge assembly and a sleeve. The body may define a cavity having an opening. The closure member may be movable relative to the cavity to provide access to the cavity. The hinge assembly may be attached to the body and the closure member and may include first and second torsion rods extending between first and second sides of the opening of the cavity. The first and second torsion rods may urge the closure member toward an open position. The sleeve may be attached to the first torsion rod and may include an outer surface having a profile defining a plurality of peaks and valleys. The outer surface may contact the second torsion bar to prevent direct contact between the first and second torsion rods.
