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.

Claim 1
Independent Claim
45 words
A latch as defined in claim 1 in which said rotors are offset axially from one another and lie in first and second side-by-side planes, said first and second detents also being offset from one another and lying in said first and second planes, respectively.
Claim 2
Dependent Claim
79 words
A latch as defined in claim 2 in which said first detent comprises a hook on the inner end portion of said pawl and positioned to engage the inner edge of the inner leg of said lower rotor when the latter is in its fully latched position, said second detent comprising a lug positioned outwardly of said first detent and positioned to block against a shoulder on said upper rotor when the latter is in its fully latched position.
Claim 3
Dependent Claim
39 words
A latch as defined in claim 3 in which said hook is formed integrally with said pawl, said lug being formed separately of said pawl but being anchored rigidly to the pawl to turn in unison with the latter.
Claim 4
Dependent Claim
74 words
A latch as defined in claim 3 in which said rotors turn through secondary latched positions in turning from said unlatched positions to said fully latched positions, said hook being engageable with the inner edge of the outer leg of said lower rotor to hold the latter in its secondary latched position, and said lug being engageable with a second shoulder on said upper rotor to hold the latter in its secondary latched position.
Claim 5
Dependent Claim
45 words
A latch as defined in claim 1 further including a single spring for biasing said pawl into engagement with said rotors, said spring acting through said pawl to bias said rotors toward said unlatched positions as the rotors are moved from their fully latched positions.
