Abstract: A polymeric steering column housing assembly is provided formed from a plurality of components interconnected together using conventional fastening methods for housing a tilting and/or telescoping steering column shaft assembly. In one form of the invention, the steering column housing assembly includes a lower housing member formed from at least two mating parts. Pivotally coupled to the lower housing assembly is an upper steering column assembly likewise formed from at least two mating parts interconnected together. The upper and lower housing members are in turn interconnected by a positioning locking system to control the tilt position of the upper housing member relative to the lower housing member.

Abstract: An alarm assembly is provided alerting the operator through one of a visual, audible, or tactile signal, the occurrence of a specified event. The alarm assembly includes a locking mechanism coupled to a substrate which has a natural frequency. The locking mechanism is maintained in a condition which inhibits the natural frequency of the substrate unless commanded to do so by an electronic circuit which includes sensors for monitoring one or more specific criterion. The locking mechanism is preferably a non-Newtonian flow fluid locking mechanism which uses a magneto-rheological fluid to dynamically adjust the locking strength of the locking mechanism as well as the natural frequency of the substrate based upon user inputs and dynamic events. The alarm assembly can be dynamically “tuned” in and out of the natural frequency of the substrate so the substrate vibrates, produces an audible noise, or generates a current upon the occurrence of a predetermined event.

Abstract: A steering column assembly comprising an outer isolator tube closed at one end and open at an opposite end; at least one tubular resilient member concentrically disposed within and adhered to an inner wall of the outer isolator tube; and an inner isolator tube concentrically disposed within and adhered to an inner wall of the resilient member, the inner isolator tube member having one end extending from the open end of the outer isolator tube. A telescoping shaft insert assembly is provided having a first end concentrically received within an inner wall of the inner isolator tube and with an opposite end of the telescoping shaft assembly from the open end of the outer isolator tube. The tubular resilient member disposed between the outer and inner isolator tubes is preferably made from a polymeric material and absorbs or dampens transient noise and vibration produced by the road and sensed at the steering wheel. This results in reduced fatigue for the operator.

Abstract: A tilt-adjustable steering column assembly, comprising in combination an upper housing pivotally attached to a lower housing along a generally horizontal axis transverse to the upper and lower housings, the pivotal attachment accomplished by a pair of pins, each having a threaded intermediate shaft received in a threaded opening extending through opposite sides of the lower housing, and further having generally hemispherical pins, each received in a complementary-shaped recess formed on opposite sides of the upper housing to form a hemispherical bearing surface and preloading the upper housing in compression.
