ANTITHEFT TYPE DOOR LOCK SYSTEM

摘要

When a so-called antitheft operation is carried out by using a key plate or the like from outside a motor vehicle, a reversible electric motor 1 is energized to rotate a worm wheel 3 with a projection 3b which is thus brought into sliding engagement with an arm 12 of an antitheft lever 9, thereby to pivot the lever 9 from a cancelling position (fig 5) to an antitheft position (fig 2) in which an operation lever 6 synchronously movable with a locking-unlocking lever 102 of a door latch device 104 is locked in its locking position by the engagement of projection 66 of lever 6 in recess 9d of the lever 9.
