JuniorPivot 4-Bar Knee

Children fall, and a pediatric knee's geometry is its first line of defense. The JuniorPivot's four-bar linkage places its instant center well posterior at heel strike, buying stance security without a lock, while the shortened swing-phase shank adds the toe clearance small hip flexors appreciate on stairs and curbs.

Links are machined aluminum on sealed bearings sized for pediatric loads, with friction swing control and a soft extension stop tuned quiet for classrooms. Build height is 102 mm, mass 310 g, flexion 145 degrees for floor play, and the rating is 45 kg.
