Abstract
A folding chair includes front and rear leg members, armrest members, a backrest support member, and a seat that are pivotally connected to one another to enable collapsing or extending of the folding chair. The folding chair is characterized in that the armrest members are provided with two long slots forward extended from joints of the armrest members and upper ends of the rear leg member, that an auxiliary brace is provided between each armrest member and the backrest support member, and that a pair of knuckle plates for pivotally connecting the backrest support member, the seat, and the rear leg member to one another have length-increased lower extension portions to enable downward pulling of the backrest support member and the seat to a lowered position when the folding chair is collapsed, so as to effectively reduce the collapse height and volume of the chair.
