Composite steering column housing
First Claim
1. A steering column assembly, comprising in combination:
- a lower steering column housing formed from at least a first and a second mating member interconnected together transversely relative to a longitudinal passage extending between an upper and a lower end of said lower steering column housing, said longitudinal passage having at least one bearing seat formed therein;
an upper steering column housing formed from at least a first and a second mating member interconnected together transversely relative to form a longitudinal passage extending between an upper and a lower end of said upper steering column housing, said lower end of said longitudinal passage within said upper steering column housing having an inside diameter greater than an inside diameter of said upper end with said longitudinal passage having at least one bearing seat formed therein, said lower end of said upper steering column housing pivotally coupled to said upper end of said lower steering column housing such that said upper steering column housing pivots between a first and a second position relative to said lower steering column housing; and
a positioning device interconnecting said upper steering column housing with said lower steering column housing to adjustably hold a pivot position of the upper steering column housing relative to the lower steering column housing.

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.

7. A tiltable steering-column housing for a motor vehicle, comprising in combination:
-
a lower member formed from at least two injection-molded halves coupled together along a longitudinal axis substantially parallel to a longitudinal passage interconnecting an upper end to a lower end of said lower member, said longitudinal passage of said lower member having at least one bearing seat farmed therein; an upper member formed from at least two injection-molded halves coupled together along a longitudinal axis substantially parallel to a longitudinal passage interconnecting an upper end to a lower end of said upper member, said longitudinal passage of said upper member having at least one bearing seat formed therein, said lower end of said upper member pivotally interconnected to said upper end of said lower member such that said upper member pivots between a first and a second position relative to said lower member; a journal bearing configured to be disposed within each of said at least one bearing seat formed in each of said lower and upper member; a lower and an upper steering column shaft configured to be disposed within a respective one of said longitudinal passages defined in each of said lower and upper members, and journaled within each longitudinal passage by said journal bearing; and a universal coupler for interconnecting said lower and upper steering column shafts.
