Claim 0:
1. A generator drive disconnect device of a generator arranged to be driven by an aircraft engine, the disconnect device comprising:
a drive transfer means for transferring drive from an input shaft of the generator to a rotor of the generator, the drive transfer means having a connected configuration and a disconnected configuration;
a disconnect mechanism configured to move the drive transfer means from the connected configuration to the disconnected configuration; and
a latch mechanism configured to hold the drive transfer means in the disconnected configuration, the latch mechanism comprising:
a support structure;
a latch member, moveable between an extended position in which the latch mechanism restricts movement of the drive transfer means from the disconnected configuration to the connected configuration, and a retracted position in which the latch mechanism does not restrict movement of the drive transfer means from the disconnected configuration to the connected configuration; and
a biasing mechanism configured to generate a biasing force to bias the latch member towards the extended position and to apply a reaction force to the latch member to resist movement of the latch member towards the retracted position, the reaction force having a magnitude which increases as the distance of the latch member from the retracted position increases.
