Abstract
A spring arch system for a shoulder pad, such as a football shoulder pad. The spring arch system comprises inner and outer arches of generally inverted U-shape as viewed from the side. The outer arch extends substantially over the inner arch from a forward portion of the inner arch to a rearward portion of the inner arch. The spacing between the arches is such that the arches form a generally wedge-shaped configuration at least in the area of the top of the inverted U-shape. Impact on the outer arch causes deformation thereof relative to the inner arch, and thus some of the energy of the impact is absorbed through such relative deformation.
