Seat Frame For A Folding Chair

Abstract

A seat frame for a folding chair includes a support rail of an increased size that extends from a bottom edge of the seat frame toward a central area of the seat frame. The support rail is used for placing a seat cushion of the folding chair thereon. A plurality of through-holes is formed on the support rail, and a plurality of threaded holes is formed through a bottom of the seat cushion corresponding to the through-holes. When the seat cushion is placed on the support rail, the threaded holes are in alignment with the through-holes, and a plurality of fasteners are engaged via the through-holes with the threaded holes so as to directly fix the seat cushion on the support rail of the seat frame. The strength of the seat cushion for sustaining a load can be thereby enhanced.
