Title (EN) COMBINED CYLINDRICAL AND CONICAL SPRINGS
(FR) RESSORTS ASYMÉTRIQUES ASSOCIANT RESSORTS CYLINDRIQUES ET CONIQUES
Abstract: front page image
(EN)A mattress comprising asymmetrical coil springs with nonlinear spring rates provides comfort to users with different weights. The lower portion of the spring is cylindrical and the upper portion is conical or frustoconical. This arrangement causes the spring to undergo linear compression before undergoing nonlinear compression. The result is a mattress that is sufficiently soft for lighter users and sufficiently firm for heavier users.
(FR)L'invention concerne un matelas comprenant des ressorts hélicoïdaux asymétriques à flexibilité non linéaire assurant le confort d'utilisateurs de poids différents. La partie inférieure du ressort est cylindrique et la partie supérieure est conique ou tronconique. Ce dispositif permet au ressort de subir une compression linéaire avant de subir une compression non linéaire. Il en résulte un matelas qui est suffisamment confortable pour les utilisateurs de faible poids et suffisamment ferme pour les utilisateurs de poids plus élevé.
