Steering column lock cylinder module

1. A lock cylinder module, comprising:

a keyed cylinder sleeve having an elongate body that extends between a first end and a second end along an axis, the keyed cylinder sleeve being arranged to receive a keyed cylinder that extends between a first keyed cylinder end and a second keyed cylinder end, the second keyed cylinder end having a pin being disposed proximate the second end,

the elongate body having,

a first face, second face, and a rim surface extending between the first face and the second face, disposed proximate the first end of the keyed cylinder sleeve;

a first arm extending from the second face towards the second end, the first arm defining a chamfered region disposed proximate a distal end of the first arm and at least one notch; and

an anti-rotation feature disposed adjacent to the first arm and disposed proximate the second end, the pin engaging the anti-rotation feature while the keyed cylinder is in a first position to inhibit rotation of the keyed cylinder towards a second position.

2. The lock cylinder module of claim 1 , wherein the anti-rotation feature includes an anti-rotation feature body extending between a first anti-rotation feature end and a second anti-rotation feature end along the axis.

3. The lock cylinder module of claim 2 , wherein the anti-rotation feature body has a first ramp surface, an end surface, a first planar surface extending between the first ramp surface and the end surface, a second planar surface disposed opposite the first planar surface, a second ramp surface that extends between the second planar surface and the first ramp surface, and an end feature surface that extends between the first ramp surface, the first planar surface, the end surface, the second planar surface, and the second ramp surface at the second anti-rotation feature end.

4. The lock cylinder module of claim 3 , wherein while the keyed cylinder is in the first position, the pin engages the end surface of the anti-rotation feature to inhibit rotation of the keyed cylinder towards the second position.

5. The lock cylinder module of claim 4 , wherein in response to translation of the keyed cylinder towards the second end of the keyed cylinder sleeve the pin extends beyond the anti-rotation feature.

6. The lock cylinder module of claim 5 , wherein in response to rotation of the keyed cylinder towards the second position about the axis while the pin is extended beyond the anti-rotation, the pin is disposed proximate the ramp surface of the anti-rotation feature to enable the keyed cylinder to further move towards the second position.

7. The lock cylinder of claim 3 , wherein the first ramp surface intersects the second ramp surface at an intersection point.

8. The lock cylinder module of claim 2 , wherein the first anti-rotation feature end is disposed proximate the at least one notch.

9. A keyed cylinder sleeve, comprising:

a body extending between a first end and a second end along an axis, the body having a first face and a second face disposed about the first end, an inner bore configured to receive a keyed cylinder, and a holding block extending from the second face towards the second end; and

an anti-rotation feature connected to the body and disposed adjacent the holding block, the anti-rotation feature has a first ramp surface, an end surface, a first planar surface extending between the first ramp surface and the end surface, a second planar surface disposed opposite the first planar surface, a second ramp surface that extends between the second planar surface and the first ramp surface, and an end feature surface that extends between the first ramp surface, the first planar surface, the end surface, the second planar surface, and the second ramp surface at an end of anti-rotation feature.

10. The keyed cylinder sleeve of claim 9 , wherein the body further defines a block radially spaced apart from the holding block and extending from the second face towards the second end.

11. The keyed cylinder sleeve of claim 9 , wherein the holding block includes a first arm and a second arm disposed substantially parallel to the first arm.

12. The keyed cylinder sleeve of claim 11 , wherein the second arm defines a chamfered region disposed proximate a distal end of the first arm.

13. The keyed cylinder sleeve of claim 9 , wherein the holding block and the anti-rotation feature are spaced apart from the keyed cylinder received within the inner bore.

14. The keyed cylinder sleeve of claim 13 , wherein keyed cylinder is rotatable between a first position and a second position and longitudinally displaceable along the axis.

15. The keyed cylinder sleeve of claim 14 , wherein while the first position a pin extending from the keyed cylinder engages the end surface of the anti-rotation feature and the anti-rotation feature inhibits rotation of the keyed cylinder from the first position towards the second position.

16. The keyed cylinder sleeve of claim 15 , wherein in response to longitudinally displacing keyed cylinder along the axis, the pin extends beyond the end feature surface, and the keyed cylinder is enabled to rotate towards the second position.

17. The keyed cylinder sleeve of claim 16 , wherein while the keyed cylinder is in the second position, the pin is disposed proximate the ramp surface and the chamfered region.

18. The keyed cylinder sleeve of claim 17 , wherein the first position is a run position of a vehicle ignition system.

19. The keyed cylinder sleeve of claim 17 , wherein the second position is a non-run position of the vehicle ignition system.
