Abstract:
An automotive door lock assembly for use with an automotive door having outside and inside handles and a key cylinder mounted thereon, comprising:a door lock including a first lock/unlock mechanism which switches between an unlock condition wherein manipulation of said outside handle is made operative and a lock condition wherein manipulation of said outside handle is made inoperative and a second lock/unlock mechanism which switches between an unlock condition wherein manipulation of said inside handle is made operative and a lock condition wherein manipulation of said inside handle is made inoperative; and an electric actuator mounted to said door lock for actuating the same, said electric actuator including: a housing secured to a base member of said door lock; first and second electric motors installed in said housing; a first operation lever straightly movably held by said housing, said first operation lever being actuated by said first electric motor to switch between an unlock position to cause said first lock/unlock mechanism to assume said unlock condition and a lock position to cause said first lock/unlock mechanism to assume said lock condition; and a second operation lever pivotally held by said housing, said second operation lever being actuated by said second electric motor to switch between an unlock position to cause said second lock/unlock mechanism to assume said unlock condition and a lock position to cause said second lock/unlock mechanism to assume said lock condition, in which said electric actuator further includes: a first structure which moves said first operation lever to either one of the lock and unlock positions in response to manipulation of said key cylinder mounted on the door; and a second structure which is connected between the first operation lever and the second operation lever and moves said second operation lever to the unlock position when said first operation lever is moved from the lock position to the unlock position.
