Publication number: 20090188342Abstract: An adjustable steering column assembly having a repositionable steering column and a break-away lever arm. The lever arm has a first mounting interface and an adjustment assembly member operably coupled with the steering column has a second mounting interface. Engagement of the first and second mounting interfaces mounts the lever arm on the adjustment assembly member. Movement of the lever arm rotates the adjustment assembly member to facilitate the repositioning of the steering column. Applying a breakaway force exceeding a threshold value to the lever arm disengages the mounted lever arm from the adjustment assembly member by relative translational movement between the first and second mounting interfaces. Some embodiments employ a threaded fastener installed to a predetermined torque to bias the first and second mounting interfaces into engagement. The threaded fastener can be installed such that it may be non-frangibly disengaged by displacement through the open end of a slot.Type: ApplicationFiled: January 30, 2008Publication date: July 30, 2009Inventors: William D.

Publication number: 20090185879Abstract: 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.Type: ApplicationFiled: January 22, 2008Publication date: July 23, 2009Inventor: William D.
