Title (EN) COIL SPRINGS WITH NON-LINEAR LOADING RESPONSES AND MATTRESSES INCLUDING THE SAME
(FR) RESSORTS HÉLICOÏDAUX À RÉPONSES À CHARGE NON LINÉAIRE, ET MATELAS COMPRENANT CEUX-CI
Abstract: front page image
(EN) A spring is provided that exhibits a variable and non-linear loading response upon compression. The spring comprises a continuous wire having a lower end convolution, an upper end convolution, and a plurality of helical intermediate convolutions. The upper end convolution, the lower end convolution, and the helical intermediate convolutions each have a respective diameter, with the continuous wire further defining a pitch between the various convolutions. In the spring, one or more of the diameters of the convolutions or one or more of the pitches varies along the length of the continuous wire such that the spring exhibits a non-linear loading response upon compression. A mattress is further provided and includes a plurality of the springs arranged in a matrix.
(FR) Ressort qui présente une réponse à charge variable et non linéaire lors de la compression. Le ressort comprend un fil continu ayant une convolution d'extrémité inférieure, une convolution d'extrémité supérieure et une pluralité de convolutions intermédiaires hélicoïdales. La convolution d'extrémité supérieure, la convolution d'extrémité inférieure et les convolutions intermédiaires hélicoïdales ont chacune un diamètre respectif, le fil continu délimitant en outre un pas entre les différentes convolutions. Dans le ressort, un ou plusieurs des diamètres des convolutions ou un ou plusieurs des pas varient sur la longueur du fil continu de telle sorte que le ressort présente une réponse à charge non linéaire lors de la compression. L'invention concerne en outre un matelas qui comprend une pluralité des ressorts agencés dans une matrice.
