International Classification:

A62B 35/00
E04G 21/32
F16H 21/54
F16H 35/18

Abstract:

The present system for fall restraint includes a mounting frame connected to a trigger mechanism and firing blocks, with a trigger cable extending through apertures in the mounting frame and trigger mechanism. Sudden movement by a user, such as a fall, actuates the trigger mechanism to trigger the firing blocks. The firing blocks are loaded with anchors and firing cartridges. Triggering the firing blocks causes the cartridges to fire, propelling the anchors into an anchoring surface, such as a roof. Because the user is connected to the trigger cable, once the anchors deploy the user is anchored to the roof and their fall arrested.
