Abstract

The invention relates to a device which relieves lumbar pain caused by the concavity of certain chairs. It consists of a single article made by moulding flexible and strong rubber. It has the rear part 6, 7, 8 and 9, the longest of the device, convex and chamfered in thickness H along the direction of the length F, with the ends 6 and 5 in the shape of a wing. The rear thickness H, convex downwards in length F, thins towards the ends 6; according to certain variants, the rear thickness H varies between 2 and 8 centimetres depending on the type used. Furthermore, the rear thickness H decreases in the direction of the width G towards the front of the part 10. It is provided with a flat top 1, with the front 2 and 4 straight, and the corners 3 rounded; the bottom 11 is flat and thin. The device according to the invention is in particular intended to eliminate lumbago due to the concavity of certain chairs.

Description

La présente invention concerne un dispositif qui supprime nettement les atteintes à la colonne vertébrale des personnes assises. The present invention relates to a device which clearly removes damage to the spine of seated people.

Le dispositif selon l'invention, remédie à ces maux. The device according to the invention remedies these ailments.

Il est constitué d'un coussin qui épouse et comble la forme concave du dessus d'un siège, redonnant une position assise sans dangers pour la colonne vertébrale. It consists of a cushion that hugs and fills the concave shape of the top of a seat, giving a seated position without danger to the spine.

Il présente une partie supérieure (1) sensiblement plate ; une partie arrière (6) (7) (8) et (9) plus longue que sa partie avant ; convexe dessous (9) en vue de profil arrière, et s'amincissant aux extrémités (6) pour épouser la concavité du dessus du siège où elle s'adapte g décrotssant vers l'avant, où elle est prolongée par une partie amincie (11).It has a substantially flat upper part (1); a rear part (6) (7) (8) and (9) longer than its front part; convex below (9) in rear profile view, and tapering at the ends (6) to match the concavity of the top of the seat where it adapts to the front, where it is extended by a tapering part (11 ).

Selon une forme de réalisation appropriée, le dispositif est fabriqué en caoutchouc souple et résistant obtenu d'une seule pièce par moulage ; il s'utilise sans fixation et peut entre habillé d'une housse. According to an appropriate embodiment, the device is made of flexible and resistant rubber obtained in one piece by molding; it can be used without fixing and can be dressed with a cover.

L'épaisseur arrière à l'endroit de Sa convexité maximale, est comprise entre 2 et 8 centimètres Les dessins annexés illustrent l'invention. The rear thickness at the point of its maximum convexity is between 2 and 8 centimeters. The attached drawings illustrate the invention.

La figure 1 représente en vue de dessus le dispositif selon l'invention. Figure 1 shows a top view of the device according to the invention.

L'arrière (6) (7) (8) et (9) est indiqué en largeur (b) et en longueur (F), dont les extrémités en forme d'aile définies par les parties (6) et (5) participent au centrage de l'ensemble et aident à répartir la pression appliquée sur celui-ci.The rear (6) (7) (8) and (9) is indicated in width (b) and in length (F), the wing-shaped ends defined by the parts (6) and (5) participate in centering the assembly and help to distribute the pressure applied on it.

L'avant (2) et (4) est noté en largeur (B) et en longueur (E) ; il est moins long et plus large que l'arrière, ses d tés sont droits et minces, les angles (3) arrondis.The front (2) and (4) is noted in width (B) and in length (E); it is shorter and wider than the rear, its tees are straight and thin, the angles (3) rounded.

La figure 2 représente en vu. de profil le dispositif selon l'invention. Figure 2 shows in view. in profile, the device according to the invention.

L'épaisseur arrière (E) est biseautée avec inclinaison vers l'arrière du dessus (7) vers le dessous (9), (D) montre11 notre épaisseur du biseautage ; elle décroît en dégradé (représenté en grisé sur les figures 3 et 4) vers l'avant de la partie (10) en se rétrécissant vers l'axe médian, où elle est prolongée par une partie amincie (11) présentant un dessous plat.The rear thickness (E) is bevelled with tilting backwards from the top (7) to the bottom (9), (D) shows our thickness of the bevel; it decreases in gradation (shown in gray in FIGS. 3 and 4) towards the front of the part (10) while narrowing towards the median axis, where it is extended by a thinned part (11) having a flat underside.

La figure 3 représente en vue de dessous le dispositif selon l'invention. Figure 3 shows a bottom view of the device according to the invention.
