Abstract

An ignition lock assembly includes a lock housing and an ignition lock actuator assembly. The lock housing has a first portion and a second portion that extends from the first portion along an axis. The ignition lock actuator assembly is received within the second portion. The ignition lock actuator assembly includes an actuator gear and a lock cylinder drive disk. The lock cylinder drive disk is at least partially received within the actuator gear. The lock cylinder drive disk has a drive disk body that extends between a first disk end and a second disk end. The first disk end has an inhibit feature.

First claim

Having thus described the invention, it is claimed:

1 . An ignition lock assembly, comprising:
an ignition lock actuator assembly received within a lock housing, the ignition lock actuator assembly, comprising:
an actuator gear having a base and an annular wall extending from the base, the base and the annular wall defining a cavity;
a lock cylinder drive disk at least partially received within the cavity, the lock cylinder drive disk having a drive disk body extending between a first disk end and a second disk end along an axis, the first disk end having an inhibit feature configured to selectively engage a stop feature extending from a keyed cylinder sleeve that is at least partially received within the lock housing having a keyed cylinder movable between a first position and a second position; and
a biasing member disposed between the actuator gear and the lock cylinder drive disk, the biasing member configured to bias the first disk end towards the keyed cylinder sleeve.

2 . The ignition lock assembly of claim 1 , wherein the inhibit feature includes a first inhibit surface extending from the first disk end, a second inhibit surface extending from an end of the first inhibit surface, and a third inhibit surface extending between the second inhibit surface and the first disk end.

3 . The ignition lock assembly of claim 2 , wherein the stop feature includes a first stop surface extending from a keyed cylinder sleeve end surface, a second stop surface extending from an end of the first stop surface, and a third stop surface extending between the second stop surface and the keyed cylinder sleeve end surface.

4 . The ignition lock assembly of claim 3 , wherein the first inhibit surface engages the first stop surface while the keyed cylinder received within the keyed cylinder sleeve is in the first position, to inhibit movement of the keyed cylinder between the first position and the second position.

5 . The ignition lock assembly of claim 4 , wherein the drive disk body defines a first opening extending from the first disk end towards the second disk end.

6 . The ignition lock assembly of claim 5 , wherein the drive disk body defines a second opening extending from the second disk end towards the first disk end, the second opening is disposed coaxially with the first opening.

7 . The ignition lock assembly of claim 6 , wherein the drive disk body includes a shelf disposed between the first opening and the second opening.

8 . The ignition lock assembly of claim 7 , wherein the keyed cylinder includes an extension member extending through the first opening and the second opening of the drive disk body.

9 . The ignition lock assembly of claim 8 , wherein in response to a longitudinal displacement of the keyed cylinder along the axis, the extension member moves the second disk end towards the base of the actuator gear to release the first inhibit surface from engagement with the first stop surface and enables the keyed cylinder to be rotated towards the second position.

10 . The ignition lock assembly of claim 9 , wherein the third inhibit surface engages the third stop surface while the keyed cylinder is in the second position.

11 . An ignition lock assembly, comprising:
a lock housing having a first portion, a second portion extending from the first portion along an axis, and a shoulder inwardly extending from at least one of the first portion and the second portion towards the axis, the shoulder defining a ramped region disposed adjacent to a notch defined between a first edge and a second edge of the shoulder, the first portion being configured to receive a keyed cylinder having a guide feature extending radially from the keyed cylinder, the keyed cylinder moveable between a first position and a second position, the guide feature being configured to engage the first edge to inhibit movement of the keyed cylinder from the first position towards the second position.

12 . The ignition lock assembly of claim 11 , wherein the guide feature is spaced apart from the ramped region and the first edge while the keyed cylinder is in the second position.

13 . An ignition lock assembly, comprising:
a lock housing having a first portion and a second portion extending from the first portion along an axis; and an ignition lock actuator assembly received within the second portion, the ignition lock actuator assembly, comprising:
an actuator gear; and
a lock cylinder drive disk at least partially received within the actuator gear, the lock cylinder drive disk having a drive disk body extending between a first disk end and a second disk end, the first disk end having an inhibit feature.

14 . The ignition lock assembly of claim 13 , further comprising a biasing member disposed between the actuator gear and the lock cylinder drive disk.

15 . The ignition lock assembly of claim 14 , wherein the drive disk body defines a first opening extending from the first disk end towards the second disk end.

16 . The ignition lock assembly of claim 15 , wherein the first disk end faces towards a keyed cylinder rotatably disposed within a keyed cylinder sleeve that is at least partially received within the first portion.

17 . The ignition lock assembly of claim 16 , wherein the keyed cylinder sleeve includes a stop feature extending from a keyed cylinder sleeve end surface and an extension member spaced apart from stop feature and extending from a keyed cylinder end.

18 . The ignition lock assembly of claim 17 , wherein the keyed cylinder is rotatable within the keyed cylinder sleeve about the axis between a first position and a second position and is longitudinally displaceable along the axis.

19 . The ignition lock assembly of claim 18 , wherein a first inhibit surface of the inhibit feature engages a first stop surface of the stop feature while the keyed cylinder is in the first portion, to inhibit rotation of the keyed cylinder towards the second position.

20 . The ignition lock assembly of claim 18 , wherein in response to a longitudinal displacement of the keyed cylinder along the axis, the extension member of the keyed cylinder moves the lock cylinder drive disk to compress the biasing member and releases the first inhibit surface of the inhibit feature from engagement with the first stop surface of the stop feature, to enable rotation of the keyed cylinder towards the second position.

21 . A lock cylinder drive disk, comprising:
a drive disk body extending between a first disk end and a second disk end along an axis, the drive disk body defining a first opening that extends from the first disk end towards the second disk end and an inhibit feature on the first disk end that is spaced apart from the first opening, the inhibit feature being configured to selectively engage a stop feature extending from a keyed cylinder sleeve to selectively inhibit movement of the keyed cylinder sleeve between a first position and a second position.
