US Patent 10583770 Mechanically actuated cargo restraint system

A mechanically actuated cargo restraint system for a vehicle includes a rotatable reel in a frame, a first flexible tether, a base and a pawl. The frame includes a cog having a single tooth. The first flexible tether has a first end coupled to the rotatable reel and a second end capable of being coupled to one of a vehicle and a cargo item. The first flexible tether is windable around the rotatable reel. The base rotate with the reel. The pawl is pivotally connected to the base, and is biased in a first position that allows rotation of the pawl with respect to the cog. The pawl moves to a second position responsive to centrifugal force associated with a velocity of rotation of the rotatable reel exceeding a threshold. The pawl engages the cog in the second position to inhibit relative movement of the pawl with respect to the cog.
