to said housing in at least one direction.
a lever arm rotatable about said axis and coupled to an actuator output;
a second pawl coupled to said lever arm and releasably engagable with said disc to resist rotation of said lever arm relative
to said disc in at least one direction;
an energy storage feature coupled to said disc, said energy storage feature rotating said disc in a first direction when said
stored energy is released; and
a gear rotatable about said axis, said gear comprising a first release capable of disengaging said first pawl from said disc,
and a second release feature capable of disengaging said second pawl from said disc;
said gear configured to load said energy storage feature, and release said first pawl permitting rotation of said disc and
