Claim:
1. An actuator for preventing rotation of a rotary component including a plurality of teeth, comprising: a first pawl pivotable about a first pivot axis and engageable with said rotary component for preventing rotation of the rotary component in a first rotary direction, said first pawl being spring biased toward an engaged position with said rotary component; a second pawl pivotable about a second pivot axis and engageable with said rotary component for preventing rotation of the rotary component in a second rotary direction opposite the first rotary direction, said second pawl being spring biased toward an engaged position with said rotary component; a first solenoid including a first electrically activated solenoid and a first armature movable from a first position for holding said first pawl out of engagement with the rotary component to a second position for allowing said first pawl to be engaged with the rotary component; and a second solenoid including a second electrically activated solenoid and a second armature movable from a first position for holding said second pawl out of engagement with the rotary component to a second position for allowing said second pawl to be engaged with the rotary component; wherein said first and second pawls each include a first end engageable with the rotary component and a second end engageable directly by said first and second armatures of said first and second solenoids; wherein said first and second armatures are biased toward said first position by a return spring; wherein said first and second armatures are biased toward said first position by a return spring.
