Abstract

A travel control system for a cam assembly includes a cam having a plurality of lobes on a first face of the cam. Also included is a cam follower engageable with the first face of the cam to follow the lobe profile defined by the plurality of lobes. Further included is a pair of cam prongs extending outwardly from an outer perimeter of the cam. Yet further included is a lock indicator cam follower tab in contact with a first cam prong of the pair of cam prongs in a locked position of the cam assembly and in contact with a second cam prong of the pair of cam prongs in an unlocked position of the cam assembly.

First claim

Having thus described the invention, it is claimed:

1. A travel control system for a cam assembly, the travel control system comprising:
a cam having a plurality of lobes on a first face of the cam defining a lobe profile;
a cam follower engageable with the first face of the cam to follow the lobe profile, the cam assembly provided in a steering column assembly, the cam assembly comprising a rake lever of the steering column assembly, the rake lever being one of the cam and cam follower;
a pair of cam prongs extending outwardly from an outer perimeter of the cam; and
a lock indicator cam follower tab in contact with a first cam prong of the pair of cam prongs when the cam assembly is in a locked position and wherein the lock indicator cam follower tab is in contact with a second cam prong of the pair of cam prongs when the cam assembly is in an unlocked position, the rake lever defines an arcuate slot, the pair of cam prongs and the lock indicator cam follower tab disposed in the arcuate slot for movement therein.
