A retractable safety edge mechanism includes a safety edge for projecting ahead of a leading edge of a door, a link attached to the safety edge for pivotal fixation to the door, a lever mechanism for pivotal fixation to the door; and switch means disposed on one or both of the link and the lever mechanism operable by relative movement therebetween. Rotation of the lever mechanism in a retraction direction causes rotation of the link to retract the extended safety edge and the lever mechanism projects ahead of the safety edge. The safety edge mechanism may be incorporated into a powered door system.
