Abstract

Abstract The ignition lock includes a lock cylinder mechanism (16), mounted on the steering column, which operates an ignition pin (18) sliding in a guide housing (20). A lock recess (24) in the ignition pin accommodates part of a latching ball (26) disposed in an opening (28) in the housing, except when the pin is moved to a lock position (L) by the lock mechanism. A floor-mounted gearchange lever (36) is coupled by a cable (34) to a transmission shift pin (32) sliding in the guide housing. The ball (26) can not be accepted in the recess (24) until the ignition pin is moved from the locked position. However if the transmission shift pin (32) is in a position other than the park (P) the park recess (38) does not accommodate the latching ball. As a result the ignition pin, and therefore the ignition lock, can not be set to the locked position.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 271 words
A position control mechanism for use in a steering column-mounted lock cylinder mechanism (16) having a plurality of positions including a "Lock" position ("L"), and a floor-mounted transmission shift control mechanism (36) having a plurality of positions including a "Park" position ("P"), including interlock means (20,24,26,38) controlling the "Lock" and "Park" positions in dependence upon the relative positions of a pair of spaced members (18 and 32), characterised in that the position control mechanism comprises a guide member (20) secured to the steering column (10), an ignition pin member (18) slidably disposed in the guide member and including an axially extending "Lock" recess (24) and movable to a plurality of positions including "Lock" by the ignition lock mechanism (16), a transmission shift pin member (32) slidably disposed in the guide member and including an axially extending "Park" recess (38) facing the "Lock" recess in the ignition pin member and movable to a plurality of positions including "Park" by the transmission shift control mechanism (36), and interlock means (26) disposed in the guide member for engagement in the "Lock" recess in the ignition pin member, for preventing the ignition pin member from moving to the "Lock" position unless the "Park" recess is engaged, for engagement in the "Park" recess in the shift pin member when the shift pin member is in the "Park" position, for preventing movement of the shift pin member from the "Park" position when the ignition pin member is in the "Lock" position, and movable between the recesses when the ignition pin member is out of the "Lock" position and the shift pin member is in the "Park" position.
Claim 2
Dependent Claim 271 words
A position control mechanism for use in a steering column-mounted lock cylinder mechanism (16) having a plurality of positions including a "Lock" position ("L"), and a floor-mounted transmission shift control mechanism (36) having a plurality of positions including a "Park" position ("P"), including interlock means (20,24,26,38) controlling the "Lock" and "Park" positions in dependence upon the relative positions of a pair of spaced members (18 and 32), characterised in that the position control mechanism comprises a guide member (20) secured to the steering column (10), an ignition pin member (18) slidably disposed in the guide member and including an axially extending "Lock" recess (24) and movable to a plurality of positions including "Lock" by the ignition lock mechanism (16), a transmission shift pin member (32) slidably disposed in the guide member and including an axially extending "Park" recess (38) facing the "Lock" recess in the ignition pin member and movable to a plurality of positions including "Park" by the transmission shift control mechanism (36), and interlock means (26) disposed in the guide member for engagement in the "Lock" recess in the ignition pin member, for preventing the ignition pin member from moving to the "Lock" position unless the "Park" recess is engaged, for engagement in the "Park" recess in the shift pin member when the shift pin member is in the "Park" position, for preventing movement of the shift pin member from the "Park" position when the ignition pin member is in the "Lock" position, and movable between the recesses when the ignition pin member is out of the "Lock" position and the shift pin member is in the "Park" position.
Claim 3
Dependent Claim 68 words
A position control mechanism according to claim 1, characterised in that the interlock means comprises a ball (26) disposed in an opening (28) in the guide member (20), such that a portion of the ball is selectively engageable in the "Lock" recess (24) in the ignition pin member (18), and a portion of the ball is selectively engageable in the "Park" recess in the shift pin member (32).
