Abstract
Abstract A pawl includes a detent which hooks against one leg of a lower forked latching rotor to hold the rotor in a secondary latched position and hooks against the other leg of the rotor to hold the rotor in a fully latched position. A second detent on the pawl blocks against an upper latching rotor to hold the latter in its fully and secondary latched positions.
