Rotary latch lock, especially for motor vehicles

A rotary latch lock for a vehicle, arranged between two vehicle parts, one of the vehicle parts being movable and the other vehicle part being stationary, the rotary latch lock comprising:

• a rotary latch (20) and a closing member (10) connected opposed to one another on one of the two vehicle parts, respectively, the closing member (10) cooperating with the rotary latch (20), wherein the rotary latch (20) is configured to be rotatable between a closing position in which the rotary latch receives the closing member (10) and an open position in which the rotary latch releases the closing member (10′), wherein the rotary latch is configured to be spring-loaded toward the open position;
• a pivotable pawl (30) configured to be spring-loaded (33) toward a locking position, wherein in the locking position the pivotable pawl secures the rotary latch (20) in the closing position, wherein the pivotable pawl has a release position in which release position the pivotable pawl releases the rotary latch;
• handles (24, 25, 26) configured to transfer the pivotable pawl (30) by a one or more drive devices into the release position releasing the rotary latch (20), wherein the handles comprise an interior handle (24) arranged in the interior of the vehicle, an exterior handle (25) positioned externally to the vehicle, a safety handle (26) actuatable from the interior of the vehicle, and locking means (70) actuatable from the exterior of the vehicle;
• a common control lever (28) configured to switch the lock between first, second, and third states by pivoting between first, second, and third pivot positions, and wherein the safety handle (26) and the locking means (70), when actuated, are configured to act on the common control lever;
• wherein the first state is the closing state of the lock and the common control lever is in the first pivot position (28), wherein in the first state access to the vehicle is authorized via the interior handle (24) and via the external handle (25),
• wherein the second state is the locking state of the lock and the common control lever is in the second pivot position (28′), wherein in the second state access via the exterior handle (25) is denied;
• wherein the third state is the secured state of the lock and the common control lever is in the third pivot position (28″), wherein in the third state access via the external handle (27) and the internal handle (24) is denied;
• a release lever connected to the common control lever (28), wherein the release lever, when actuated by one of the handles (24 through 26) authorized to provide access to the vehicle, transfers (55) the pivotable pawl (30) into the release position.
