  • Swiveled-eye hinged-foot safety stirrup
    Patent number: 6089004
    Abstract: A stirrup has a pair of arms, an eye on the arms for receiving a strap, and a foot on the arms for supporting the foot of a rider. The eye and the foot of the stirrup are rotatable relative to the arms. The arms define a plane and the upper surface of the foot of the stirrup is perpendicular to this plane in one terminal position of the foot of the stirrup. The foot of the stirrup can only rotate backwards from this position. The eye has an opening for a strap, and the eye is freely rotatable relative to the arms through an angle of 90 degrees to and from a position in which the opening is coplanar with the arms.
