Patent attributes
The disclosed strap adjustment devices may include a pinion gear, with a first rack secured to a first strap and a second rack secured to a second strap each engaged with the pinion gear. A rotatable cam element may include an angled radially outer surface that is at an angle to a circumference of the rotatable cam element. A bearing element may be positioned adjacent to the angled radially outer surface such that the bearing element jams between the angled radially outer surface and a braking surface when the rotatable cam element is rotated in a jamming direction. A spiral spring may be coupled to the pinion gear and the rotatable cam element to allow for an increase in length of the first and second straps upon application of a tension force to the first and second straps. Various other methods, systems, and devices are also disclosed.
