Retractable anchor device includes a mounting part which is securable to a surface and a generally U-shaped member to which a tension member can be secured. The U-shaped member is slidably mounted to the mounting part and including a first end and a second end. A retracting system is included that causes the U-shaped member to move to a retracted position when the U-shaped member experiences a predetermined external force sufficient to disengage the locking system. The retracting system has at least one of (a) first and second biasing mechanisms wherein the first biasing mechanism biases the first end towards the retracted position and the second biasing mechanism biases the second end towards the retracted position, or (b) an actuator, wherein the actuator moves the U-shaped member towards at least one of the extended position and the retracted position. The U-shaped member is movable between the extended position whereby at least a portion of the U-shaped member is positioned above an upper surface of the mounting part, and the retracted position whereby the U-shaped member is positioned approximately flush with or below the upper surface of the mounting part.
