Abstract
A stirrup bushing is provided with a star-shaped cross-sectional configuration that allows structural distortion when compressed by the forces exerted by a rider. The bushing consists of an inner sleeve adapted to fit tightly around the rod of the stirrup and of outer fins extending radially along the length of the inner sleeve. In an alternative, preferred embodiment, the bushing also includes an outer sleeve enveloping the longitudinal fins, so as to provide an additional structure and an expanded surface to distribute and attenuate the forces exerted by the supporting strap over the rod of the stirrup. The invention lies in the idea of providing voids in the structure of the bushing, such that compressive forces are relieved through deformation, rather than contained in a fixed geometry that produces deterioration of the material.
