Abstract: A stirrup swivel attachment which includes a stop for stopping the pivotation of the stirrup so that the stirrup pivots freely only within a limited range. The stirrup swivel attachment includes a first horizontal web portion having a midpoint and a longitudinal axis; a horizontal u-shaped member having a second horizontal web portion with a midpoint, a longitudinal axis and two ends, and having flange portions that extend vertically upward from the ends of the second horizontal web portion; a pin for pivotally connecting the first and second horizontal web portions at the midpoints thereof; and a stop disposed on the first horizontal web portion at a point removed from the midpoint thereof for stopping the second horizontal web portion when the first horizontal web portion is pivoted about the pin so that the longitudinal axes of the first and second horizontal web portions cannot become vertically aligned.
