Abstract

The invention relates to a folding chair (10) comprising a frame (12) on which a seat part (14) can be pivoted about a folding axis (16), between a folded-up idle position and a folded-down seat position. The seat part (14) applied to the chair frame (12) comprises a metal frame (28) interrupted on the front side and comprising two lateral frame parts (30) facing each other and curved in the form of a walking stick, and a connection frame part (32) connecting the two frame parts (30) on the rear side. Axle journals (24) and abutment journals extend laterally outwards from the two frame parts (30) curved in the form of a walking stick. The axle journals (24) define the folding axis (16). The abutment journals (26), together with curved longitudinal slits (22) formed in mounting surface elements (18) of the chair frame (12), define the idle position and the seat position of the seat part (14).

Claims (10)

1. A folding chair with a frame (12), on which a seat (14) is mounted between the original working position and the front working position pushed forward and pivoting around the folding axis (16), and two flat brackets (18) are fixed on the frame (12) from the sides ), each of which has an axial hole (20) and an arcuate groove (22) concentric to the axial hole (20), and axial pins (24), which are aligned with each other and installed in axial holes (20) of the brackets (18), and thrust pins (26), which are coaxial between them enter congruent arcuate grooves (22), characterized in that the seat (14) mounted on the frame (12) contains a metal frame interrupted on the front side (28) with two side parts curved in the form of a cane (30) ), from which axial pins (24) and thrust pins (26) are spaced apart in the rear sections (34) to the sides and outward, and to the connecting part (32) connecting both parts (30) from the rear side. 2. The chair according to claim 1, characterized in that both side parts (30) of the frame are made of tubular material, while the connecting part (32) of the frame is made of solid material. 3. The chair according to claim 1, characterized in that both side parts (30) of the frame at their ends distant from each other (36) are closed with plugs (40). 4. The chair according to claim 1, characterized in that the axial pin (24) and the corresponding stop pin (26) spaced from the corresponding side part (30) of the frame form, by means of the connecting section (42), an integral U-shaped element (44), which its connecting section (42) is fixed on the lower side (46) of the corresponding side part (30) of the frame. 5. The chair according to claim 1, characterized in that the connecting part (32) of the frame with its two ends (36) spaced apart from each other is fixed between the rear end portions (38) of both side parts (30) of the frame. 6. The chair according to claim 1, characterized in that the connecting part (32) of the frame is curved arcuate back and up. 7. The chair according to claim 6, characterized in that the curvature of the bend of the connecting part (32) of the frame back is greater than the curvature of the bend up. 8. The chair according to claim 1, characterized in that the frame (12) comprises a collar-like tubular frame (48) with two side posts (50) and an upper connecting element (52), while both side posts (50) are interconnected on their lower end sections (54) by means of a wall mounting bracket (56) made with mounting holes (62). 9. The chair according to claim 8, characterized in that the wall mounting bracket (56) has a flat middle part (58) made with mounting holes (62), and two end parts (60) facing each other, which form with the middle part (58), respectively, an obtuse angle, and their end edges (64) are fixed on the uprights (50). 10. The chair according to claim 8, characterized in that the mounting holes (62) are made in the form of grooves.
