Abstract

A tilt assembly (30) for a steering column assembly (10) includes a pair of downwardly disposed plates each having a slot (36); an elongated member adapted to be rotated, wherein the elongated member penetrates the slot (36) of each downwardly disposed plate and extends therebetween; a rotational member (50) located within each slot (36) and having an opening through which the elongated member is received; a biasing member (60) with a first end (62) and a second end (68), where at least one end engages with the rotational member (50). The biasing member (60) is adapted to drive rotation of the rotational member (50). When the tilt assembly (30) is in an unlocked position, the rotational member (50) is adapted to travel with respect to the slot (36), and when the tilt assembly (30) is in a locked position, the rotational member (50) is adapted to rotate and engage with a wail that is fixed with respect to the slot (36). The elongated member, rotational member (50), and biasing member (60) may be configured to eliminate lash. A steering column assembly (10) incorporating the tilt assembly (30) is also contemplated.

Description

[0001] priority claim [0002] This application claims the benefit of priority from US Provisional Patent Application No. 62 / 855,232, filed May 31, 2019, the contents of which are incorporated herein by reference in their entirety. technical field [0003] In general, the present teachings relate to improved adjustable steering column assemblies and methods associated therewith. More specifically, the present teachings relate to tilt adjustable steering column systems. Background technique [0004] For many applications, the steering column assembly incorporates one or both of a tilt or telescoping function. For these applications, levers are often employed to manually perform these functions by the vehicle user. For example, in a so-called "manual tilt and reach" steering column assembly, the assembly would have tilt ("tilt") and telescoping ("reach") functionality, with a lever provided for manual release by the vehicle user to provide options for Positioned tilt and re...
