ABSTRACT:
A folding chair includes front and rear leg frames which are pivotally connected to a seat frame, a backrest frame having a lower end portion pivoted to the rear leg frame, a pair of armrest members which have front ends pivoted to the front leg frame and rear ends pivoted to the backrest frame, and a pair of connecting rods which have front ends pivoted to the front portion of the seat frame and rear ends pivoted the backrest frame. A pair of locking plates are fixedly attached to the backrest frame and have lower portions which are movable towards two side tubes of the seat frame when the chair is unfolded. The side tubes of the seat frame are provided with resilient protrusions which are automatically engageable with engaging slots of the locking plates, respectively, when the chair is unfolded, thereby eliminating the need to operate the locking plates during folding and unfolding operations.
