  • Patent number: 8100617
    Abstract: A fastener system having a threaded shaft and a threaded body assembly. The threaded body assembly includes first and second bodies each having a threaded bore. A frangible member couples the two bodies together in an initial configuration. The two bodies are threaded onto the shaft in their initial configuration and, after one of the bodies has reached its final position on the shaft, the other body can be rotated relative to the one body and the threaded shaft thereby severing the frangible member and bringing engagement surfaces on the two bodies into bearing contact to inhibit loosening. The two bodies include recesses in their respective engagement surfaces. At least one of these recesses provides a space in which a stub of the frangible member is received when the two bodies are engaged together. The fastener system can be employed with the locking mechanism of an adjustable steering column assembly.

  • Patent number: 7896395
    Abstract: The invention provides for a collapsible steering column assembly and method for applying a varying resultant force to resist the collapse of the steering column assembly during an emergency condition. The steering column assembly includes a column jacket adapted to be releasably coupled to the frame for movement along the longitudinal axis L in the emergency condition. The column jacket includes an anvil and is supported by a support bracket. An absorbing strap secured to the supporting bracket is routed around the anvil. The absorbing strap is plastically deformed as the column jacket moves along axis L and an actuator supported by the support bracket applies a force against the absorbing strap. The actuator selectively varies the applied for as the absorbing strap is drawn over the anvil in the emergency condition to optimize the resultant force for the emergency condition.
