Safety stirrup for horse riding

A safety stirrup for horse riding, the safety stirrup comprising:

• a frame structure which comprises a hooking portion for a stirrup leather, a support element for a user's foot, and a first side arm adapted to rigidly connect a first edge portion of the support element to the hooking portion;
• a second side arm extending between a second edge portion of the support element and the hooking portion so as to define a stirrup opening adapted to be engaged, in use, by the user's foot,
• wherein the second side arm is hinged with a joint end to the frame structure and rotatably movable between a closed position where the second side arm laterally delineates the stirrup opening, and an open position where a free end of the second side arm, opposed to the joint end, is spaced from the frame structure so as to allow lateral disengagement of the user's foot from the stirrup opening;
• and
• a safety arm rigidly connected to the second side arm in correspondence of the joint end and movable integrally therewith in the stirrup opening between the closed position and the open position to drive a release of the user's foot and prevent the user's foot from accidentally entering back into the stirrup opening,
• wherein the second side arm is hinged with the joint end in correspondence of the hooking portion, and the safety arm comprising at least a portion which extends parallel and in proximity to the first side arm when the second side arm is in the closed position.
