Abstract
An energy absorbing security door bar system is disclosed. The system includes a generally straight elongate member having oppositely facing free ends and the ability to resiliently flex from a straight resting position to a bowed position in which straight lines drawn through the free ends of the elongate member form an included angle of less than about 170 degrees. In addition, the system includes anchoring means for releaseably anchoring the free ends of the elongate member to opposite sides of a door's frame to prevent the door from being opened. A method for preventing forced entry through a door secured with the above security door bar system is also disclosed.
