Abstract
A latch mechanism includes a power actuator that does not require back driving of the drive train. The latch mechanism includes a latch bolt movable between a primary latched position and an open position. A first pawl secures and releases the latch bolt by moving between a latched position and released position. A release device moves between an engaged position, which allows the first pawl to reach an engaged position, and a released position, which retains the first pawl in its released position. A second pawl moves between an engaged position, which retains the release device in its released position, and a released position, which releases the release device.
