Stability restraint for vehicle spare wheel
View Patent ↗Restraining a spare wheel in a vehicular floor recession during a vehicle rear impact event is accomplished by securing a connection member from a first anchoring location outside of the recession to a second location within the floor recession. The spare wheel lies in the recession and a threaded bolt attached to the floor under the spare wheel passes through the center hole of the spare wheel. The threaded bolt also passes through a spare wheel holding plate that resides on the spare wheel hub to distribute a holding force from the plate to the circumference of the hub created by screwing a threaded wing nut onto the bolt passing through the holding plate. Since the belt passes from the wheel center to a location outside of the wheel's perimeter, the wheel and tire are securely restrained during the transmission of forces during a vehicular rear impact event.
1. An apparatus for restraining a spare wheel of a vehicle comprising: a tie-down bolt extending through the spare wheel and adapted to be fixedly attached to the vehicle; an anchor member positioned radially outwardly from an outer perimeter of the spare wheel and adapted to be fixedly attached to the vehicle; and a strap adapted to be fixedly coupled to the anchor member and the tie-down bolt.
2. The apparatus of claim 1 , wherein the anchor member is positioned on a floor of the vehicle.
3. The apparatus of claim 1 , wherein the anchor member is positioned on a structural cross-body member of the vehicle.
4. The apparatus of claim 1 , wherein the anchor member further comprises: an anchor bolt passing through a hole defined in the anchor member, the bolt coupled to a floor of the vehicle.
5. The apparatus of claim 1 , wherein the apparatus further comprises: a spare wheel fastener coupled to the tie-down bolt.
6. The apparatus of claim 1 , further comprising: a threaded wing nut installed on threads of the tie-down bolt to secure the strap.
7. The apparatus of claim 1 , wherein the strap is flexible.
8. The apparatus of claim 1 , wherein the strap is rigid.
9. The apparatus of claim 1 , wherein the strap is parallel to a longitudinal axis of the vehicle.
10. An apparatus to restrain a spare wheel of a vehicle, comprising: an anchor bolt adapted to be attached to a structural vehicle cross-body member; a first anchor member connected to the anchor bolt; a tie-down bolt adapted to be attached to a floor of the vehicle under the spare wheel; a second anchor member connected to the tie-down bolt; and a strap connected to the first anchor member and the second anchor member, wherein the strap extends from the first anchor member to the second anchor member over the spare wheel.
11. The apparatus of claim 10 , wherein the apparatus further comprises: a spare wheel fastener located on top of the spare wheel, the tie-down bolt passing through the spare wheel and the spare wheel fastener.
12. The apparatus of claim 10 , further comprising: a wing nut that secures onto the tie-down bolt to secure the second anchor member on the tie-down bolt.
13. A vehicle, comprising: a floor pan defining a recession to hold a spare wheel; a first anchor bolt attached to the floor pan outside of the recession; a second anchor bolt attached to the floor pan within the recession; a spare wheel fastener, through which the second anchor bolt passes, the spare wheel fastener resident upon the spare wheel and securable with a nut upon the second anchor bolt; and a connection member coupled to the first anchor bolt and extending to the second anchor bolt, the connection member placed upon the spare wheel fastener and over the second anchor bolt and secured thereto with the nut.
14. The vehicle of claim 13 , wherein the connection member is flexible.
15. The vehicle of claim 13 , wherein the connection member is rigid.
