Abstract

A footrest of a one-legged seating device includes a fixation device and a ring frame. The fixation device is integrally molded of plastic and includes a hub having a central hole and a plurality of spokes around the hub. The ring frame is a metal tube shaped into a ring. Using injection molding, the ring frame is wrapped by and fixed to circumferential ends of the spokes. A sleeve and a pressed sheet are provided between the central hole of the hub and a supporting post. A locking bolt is screwed into the fixation device. The locking bolt presses to the pressed sheet, the pressed sheet to the sleeve, and the sleeve to the supporting post. Therefore the footrest is fixed to the supporting post at a desired height.
