Closing device comprising two pawls and a motor-driven actuating mechanism
First Claim
1. A locking device comprisinga locking mechanism including a catch movable between an open position and a closed position, a pivotal first pawl movable between a latching position for holding the catch in the closed position and a release position for releasing the catch so that it can move toward its open position, and a second pawl movable between a blocking position preventing movement of the first pawl out of its latching position and an unblocking position allowing the first pawl to move out of its latching position for releasing the catch, anda motor-driven actuator, and said motor-driven actuator actuates an operating lever such that said operating lever cooperates during its movement with the second and first pawls in succession;
- wherein the second pawl is in contact with the first pawl in the blocking position, and the second pawl is not in contact with the first pawl in the unblocking position; and
wherein said second pawl comprises three legs including a blocking leg for said first pawl, a stop leg for a pivoting limiter, and a driver leg for said operating lever, wherein the three legs extend outward from a central portion of the second pawl.
