Steering column with dual direction lock

A dual direction lock to inhibit pivot movement of a first member relative to a second member, comprising:

• a mount bracket having a first sidewall and an opposite second sidewall, said first sidewall having at least one first lock feature and said second sidewall having at least one second lock feature;
• a lock bolt extending along a lock bolt axis;
• and
• a first lock cam and a second lock cam operably supported by said lock bolt for rotation about said lock bolt axis between a locked state, in response to selective rotation of said lock bolt about said lock bolt axis to a locked position, and an unlocked state, in response to selective rotation of said lock bolt about said lock bolt axis to an unlocked position, said first lock cam having at least one first lock cam lock feature, said second lock cam having at least one second lock cam lock feature, said at least one first lock cam lock feature being configured for engagement with said first lock features of said first sidewall when said first lock cam is in the locked state, and said at least one second lock cam lock feature being configured for engagement with said second lock features of said second sidewall when said second lock cam is in the locked state, wherein said first lock cam releasably locks the first member and the second member against pivotal movement relative to one another in an upward first direction when said first lock cam is in the locked state, and said second lock cam releasably locks the first member and the second member against pivotal movement relative to one another in a second downward direction when said second cam is in the locked state.

A method of preventing inadvertent tilting of a tiltable steering jacket of steering column in opposite tilt directions, comprising:

• supporting the tiltable steering jacket with a mount bracket having a first sidewall and a second sidewall spaced from the first sidewall, with the first sidewall having first positive lock features and the second sidewall having second positive lock features;
• providing a first lock cam on a first side of the tiltable steering jacket, with the first lock cam being moveable from an unlocked state, whereat the first lock cam is moved out of blocking engagement with the first positive lock features of the first sidewall to permit tilting movement of the tiltable steering jacket in opposite first and second directions, to a locked state, whereat the first lock cam is moved into blocking engagement with the first positive lock features of the first sidewall to prevent tilting movement in the first direction;
• and
• providing a second lock cam on a second side, opposite the first side, of the tiltable steering jacket, with the second lock cam being moveable from an unlocked state, whereat the second lock cam is moved out of blocking engagement with the second positive lock features of the second sidewall to permit tilting movement of the tiltable steering jacket in the opposite first and second directions, to a locked state, whereat the second lock cam is moved into blocking engagement with the second positive lock features of the second sidewall to prevent tilting movement in the second direction.
