ABSTRACT:
A folding chair includes two front legs (10, 12) which are rigidly connected at their lower ends with rearwardly oriented supporting arms (14, 16). Arm rests (24, 26) are pivotally connected with the upper ends of the legs (10, 12), and a seat plate (18) is pivotally attached at a lower point of the legs. The rear ends of the seat plate (18) and of the arm rests (24, 26) are connected by means of struts (38, 40) which are articulated on both sides. The upper ends of the legs (10, 12), the arm rests (24, 26), the rear struts (38, 40) and the seat plate (18) form a parallelogram assembly on either side of the chair so as to make it possible to fold the folding chair together into an essentially vertical position by raising the back rest. Stops (22) limit the pivoting movement of the four-bar mechanism in the seating position of the chair.
