ABSTRACT:
A latching mechanism for a movable member mounted for movement between first and second positions. The latching mechanism includes a primary latching mechanism mounted for movement between a latched position where the primary latching mechanism engages the movable member to allow the movable member to move between the first and second positions, and an unlatched position where the movable member is disengaged for movement to the second position. A secondary latching element engages the first latching mechanism to hold the primary latching mechanism in the latched position, the secondary latching element being movable to move the primary latching mechanism to the unlatched position while remaining in engagement with the primary latching mechanism.
