Automotive door lock device
First Claim
1. An automotive door lock device comprising:
- an open lever pivotal between a door latch position and a door unlatch position, said open lever having an engaging lug;
a lock/unlock lever pivotal between lock and unlock positions;
a release lever pivotal between first and second positions;
a first sub-lever having one end pivotally connected to said release lever and the other end pivotally connected to said lock/unlock lever;
a second sub-lever having one end pivotally connected to said first sub-lever and the other end formed with an actuating arm, said actuating arm being engageable with said engaging lug of said open lever; and
biasing means for biasing said second sub-lever toward said first sub-lever,wherein when said lock/unlock lever assumes said unlock position, the pivoting of said release lever from said first position to said second position induces an abutment of said actuating arm with said engaging lug of said open lever thereby to pivot a stopper pawl toward said door unlatch position, and when said lock/unlock lever assumes said lock position, the pivoting of said release lever from said first position to said second position fails to induce such abutment, andwherein when, with said actuating arm being abnormally engaged with said engaging lug, said lock/unlock lever is pivoted from said lock position to said unlock position, only said first sub-lever is permitted to move toward its unlock position against the force of said basing means keeping the abnormal engagement of said actuating arm with said engaging lug.

Abstract
An automotive door lock device comprises an open lever pivotal between a door latch position and a door unlatch position. The open lever has an engaging lug. A lock/unlock lever is pivotal between lock and unlock positions. A release lever is pivotal between first and second positions. A first sub-lever has one end pivotally connected to the release lever and the other end pivotally connected to the lock/unlock lever. A second sub-lever has one end pivotally connected to the first sub-lever and the other end formed with an actuating arm. The actuating arm is engageable with the engaging lug of the open lever. A spring is used for biasing the second sub-lever toward the first sub-lever. When the lock/unlock lever assumes the unlock position, the pivoting of the release lever from the first position to the second position induces an abutment of the actuating arm with the engaging lug of the open lever thereby to pivot the stopper pawl toward the door unlatch position, and when the lock/unlock lever assumes the lock position, the pivoting of the release lever from the first position to the second position fails to induce such engagement. Furthermore, when, with the actuating arm being abnormally engaged with the engaging lug, the lock/unlock lever is pivoted from the lock position to the unlock position, only the first sub-lever is permitted to move toward its unlock position against the force of the basing means keeping the abnormal engagement of the actuating arm with the engaging lug.
