Abstract: An improved shoulder brace having a pair of shock absorbing saddle assemblies and cups for protecting the acromioclavicular and glenohumeral joints is disclosed herein. Each saddle assembly includes a resilient, ring-shaped member for seating over and conforming to its respective acromioclavicular joint. The cups overlie each saddle assembly, and form a shock absorbing air space over each saddle assembly. Additionally, each cup includes anterior and posterior portions for protecting the front of the glenohumeral joint, and the back of the scapula respectively. Finally, each saddle assembly includes an upper arm pad which is attached to its respective saddle by means of an omni-directional hinge joint. The improved shoulder brace provides lightweight and effective protection for the shoulder joints without impairing the agility of the athlete.
