BreezeFlex 4P

Patients who garden, pray, or sit on the floor need deep flexion most knees cannot reach; the BreezeFlex 4P folds to 165 degrees while keeping pneumatic swing control for daily walking. Its four-bar geometry shortens the shank through swing, adding clearance that K2 users with weaker hip flexors notice immediately.

Links are machined from aerospace aluminum plate with hard-anodized pins, and the offset-mounted air cylinder stays protected within the frame envelope at full fold. Build height is 138 mm, mass 745 g, and the knee is rated to 125 kg with standard pyramid connections at both ends.
