ABSTRACT:
A folding chair includes two pairs of front and rear legs which are arranged at opposite sides of a seat and support the same in a substantially horizontal orientation in a position of use of the folding chair. A backrest is pivotally connected to the rear portion of the seat for movement between a plurality of inclined positions. Two armrests are hingedly connected to the backrest and extend frontwardly therefrom. The front and rear legs of each pair assume a configuration of an inverted V, and are connected to one another at their upper ends by a hinge which includes two insertable members articulated to one another, each having an insertion portion fittingly received in a hollow end portion of the respective leg. Each insertion portion has two resilient tongues at opposite sides thereof, which carry respective protuberances that are received in corresponding openings of the legs. One of the insertable members is provided with an upwardly extending arresting nose which engages, in each inclined position of the backrest, a different one of a plurality of spaced holding projections provided on the underside of the respective armrest. Each armrest is provided at its rear end with a bearing pin which extends into a blind hole of the backrest upon assembly. The bearing pin has a connecting projection and the backrest has a recess through which the projection passes into the blind hole during assembly.
