Abstract: An articulated rod adjustable in flexion-extension includes a pair of arms , a pair of outer and inner cover plates, and two rotation pins engaged in through holes of the pair of arms and the cover plates , forming a polycentric joint articulating the pair of arms in mutual rotation having flexion rotation and extension rotation directions, and two adjusting pins integral with the arms, the articulated rod having a pair of discs , on a perimeter portion with a plurality of interlocking teeth and a position indicating cursor , and having a locking element (50) adapted to engage with the plurality of interlocking teeth and with the outer cover plate , the discs axially hinged with the rotation pins and partially overlapping on parallel rotation planes, each disc bearing a slot shaped as an arc of a circle, which limits the movement of the adjusting pin(s) .

Abstract: A toothed strap for fastening devices, in particular for sports footwear is described and includes a toothed surface having a plurality of teeth arranged along a longitudinal major axis. The strap comprises a first portion and a second portion which are moulded over one another, the second portion being partially incorporated in the first portion and being made of a material having a color different from the color with which the first portion is made so as to be at least partially visible through the toothed surface.

Abstract: A toothed-belt fastening, in particular for chin-straps of helmets, protective headgear and the like, comprises a base on which the toothed belt can be slidably engaged, a first and a second pawl which are mounted in an oscillating manner on the base and can in turn be engaged with a toothing of the belt. The first pawl forms a member for unidirectionally locking the toothed belt with respect to the base and is disengageable from the toothing so as to slacken the fastening, while the second pawl is engageable with the toothing so as to tension the fastening and is hinged on the base coaxially with the first pawl.
