Closure latch

Abstract

Abstract A VEHICLE BODY DOOR LOCK INCLUDES A BOLT PIVOTALLY MOUNTED ON A FRAME FOR MOVEMENT BETWEEN LATCHED AND UNLATCHED POSITIONS AND A DETENT CARRIER PIVOTED ON THE FRAME AND CARRYING A PIVOTED LOCKING MEMBER WHICH IS NORMALLY SPRING BIASED INTO ENGAGEMENT WITH A FRAME TAB TO LOCK THE CARRIER AGAINST MOVEMENT. A DETENT IS PIVOTED TO THE CARRIER FOR UNITARY MOVEMENT THEREWITH AND MOVEMENT INDEPENDENTLY THEREOF. WHEN THE CARRIER IS IN LOCKED POSITION, A DETENT SHOULDER IS NORMALLY LOCATED IN THE PATH OF MOVEMENT OF A BOLT SHOULDER TO HOLD THE BOLT IN LATCHED POSITION. A SOLENOID IS OPERABLE TO EXTEND THE ARMATURE THEREOF AND ENGAGE THE LOCKING MEMBER TO SEQUENTIALLY FIRST RELEASE THE LOCKING MEMBER FROM ENGAGEMENT WITH THE FRAME TAB AND THEN ENGAGE THE LOCKING MEMBER WITH THE CARRIER TO SWING THE CARRIER RELATIVE TO THE FRAME. THE CARRIER MOVES THE DETENT TO A POSITION WHEREIN THE SHOULDER THEREOF IS OUT OF THE PATH OF MOVEMENT OF THE BOLT SHOULDER TO PERMIT THE BOLT TO MOVE TO UNLATCHED POSITION. WHEN THE SOLENOID IS DEENERGIZED, A TENSION SPRING BETWEEN THE CARRIER AND FRAME RETURNS THE CARRIER TO ITS INITIAL POSITION AND THE LOCKING MEMBER AGAIN ENGAGES THE LATCH FRAME. THE BOLT SHOULDER RATCHETS PAST AND INTO ENGAGEMENT WITH THE DETENT SHOULDER WHEN THE BOLT MOVES FROM UNLATCHED TO LATCHED POSITION. THE DETENT MOVES INDEPENDENTLY OF THE CARRIER DURING SUCH MOVEMENT OF THE BOLT, AND THE CARRIER REMAINS LOCKED TO THE FRAME.
