Armchair made of expanded plastic material with backrest and armrests with flat springs

The present innovation relates to an armchair made of expanded or foamed, elastic and flexible plastic material, which contains a frame for molding in this plastic material, which forms the base and the backrests of the seat. Furthermore, the armchair essentially contains a number of sinusoidal steel wire flat springs, these springs being extend through the base frame and the backrests, arcuate are curved upwards to form the entire side and back parts to support the seated person without any between contact is possible between this and the rigid frame.

This rigid frame is formed from a continuous tubular element supported by a horizontal rear piece starts at seat height and laterally forms the supports on the floor, then rises with a vertical piece and then forms a horizontal piece behind the backrest.

The armchair is firmly connected to this frame, which in turn is connected to the rear horizontal bar is. On the rigid frame are sinusoidal steel wire

Flat springs with semicircular, opposing arcs attached, uie iioriaorilal between the opposing ones front and rear sides of the backrests are arranged to form the suspension thereof; between the side part, which is based on the floor and the right and left side parts of the seat backs, are in an upwardly open The armrests arch is formed and between the rear side of the seat back and the rear side of the frame is made open arch passed up to form the backrest. The whole structure of a rigid frame and arranged accordingly Feather is incorporated into a foamed mass or expanded material in the mold during the manufacture of the upholstery.

According to FIGS. 1, 2 and 3, the armchair consists of a tubular metal frame formed from a horizontal bar 1 at the bottom of the seat, from support bars 2, 3 on the floor, from vertical struts 4, 5 and the rear horizontal bar 6. On the horizontal Rod 1 is attached to the backrest for the seat, formed from the right and left sides 7, 8 and from the rear Page 9. Reinforcements are used to stiffen the frame. Springs complete the metallic part and are in molded into the plastic mass; they are made of steel wire, which is deformed into a spring in the plane, with arcs of a circle, similar to a sine line, as in FIG. 2 can be seen. These springs are arranged in such a way that they form the seat, the anchoring and the backrest, in such a way that that they do not, as usual, by. Zi'r * ep «önuT! G work, but by bending, since they are curved> onvex and in the direction of the pressure exerted by the person sitting down. This creates an effect of the springs, which maintain the original shape and therefore with directly opposite effect against the evoked forces works, giving the user the impression of direct support at all points of the body conveyed and thus clearly promotes the relaxation of the seated person.

According to the innovation, the seat of such springs 12 is formed between the front rod 1 and the rear backrest 9 of the seat and are arranged bent upwards. The armrests of the seat are made from a number of Springs 13, 14 between the support rods 2, 3, respectively and the sides 7, 8 of the seat backs attached, namely

- see Pig. 1 - in a wide arc upwards. Finally, the backrest is made up of a large number of Feaem formed, which are mounted between the rear rod 6 and the rear side 9 of the seat back, the springs being strong are bent upwards (see Pig. 1). The whole finished pedestal frame is made in the shape of the upholstery from expanded or embedded in foamed material 16, 17, 18; the padding is shaped to work with the springs in each part for the purpose of improving the elastic effect Working together point by point in the same direction of action. The lower part of the armchair is covered with a cover 19, 20, 21 "covered or with other suitable coating material,

Ε sioh understands. that the arrangement and shape of the frame and that of the sinusoidal flat fires can be changed if desired to give the armchair different proportions; within the scope of the present innovation, however, remains the arrangement of the curved springs, which are suitable to a Counteract bending with compression.

Claims (3)

Protection requirements 1. Armchair made of expanded or foamed plastic material, characterized in that the chair consists of a rigid frame "supported by a series of Steel wire flat springs (12, 14, 15) on a sinusoidal arrangement Semicircles, these springs being arranged between parts of the frame and the backrests of the seat are that they are bent upwards to bear the weight of the seated person through bending and compression to react that frame and springs (12, 14, 15) in the foamed and expanded mass of plastic material are embedded, which forms the seat, the backrest (17) and the armrests (18) of the armchair. 2. Armchair according to claim 1, characterized in that the Springs arranged between the sides of the seat backrests are aligned in an arched manner with the curvature pointing upwards and are embedded in the plastic hat that forms the upholstery of the seat in such a way that that they are compressed under the weight of the user. 3. Armchair according to claim 1 or 2, characterized in that that the arrangement of the upward arching of the flat springs makes contact with the rigid parts of the frame with the user avoids by having each spring in the same direction by the action of the seated occupant with a clear improvement in the feeling of calm and mare reacted. - ο - 713519723.1271 Armchair according to one of claims 1 to 3, characterized in that the floor is entirely from one Cover is made of plastic material produced directly on this floor. 713519723.1171
