Title
(EN) ASSEMBLY COMPRISING AN ELASTIC STRUCTURE AND A SUPPORTING STRUCTURE
(FR) ASSEMBLAGE COMPRENANT UNE STRUCTURE ÉLASTIQUE ET UNE STRUCTURE PORTEUSE
Abstract
(EN)
The invention relates to an assembly (24) comprising: a first structure (10) extending in a first general direction (G1); a second structure (12); and a supporting structure (30) comprising supporting thread elements (32) including at least one supporting thread portion (74) extending between the first structure (10) and the second structure (12), the first structure (10) being arranged such that, for a rest length L of the first structure (10) in the first general direction (G1), elongation at maximum force Art of the first structure (10) in the first general direction (G1) satisfies the following: Art > (2π x H) / L, wherein H0 x K ≤ H with H0 being the average straight-line distance between an inner face (42) of the first structure (10) and an inner face (46) of the second structure (12) when each supporting thread portion (74) is at rest and K=0.50.
(FR)
L'assemblage (24) comprend: -une première structure (10) s'étendant selon une première direction générale (G1), -un deuxième structure (12), -une structure porteuse (30) comprenant des éléments filaires porteurs (32) comprenant au moins une portion filaire porteuse (74) s'étendant entre la première structure (10) et la deuxième structure(12), la première structure(10) étant agencée de sorte que, pour une longueur au repos L de la première structure (10) selon la première direction générale (G1), l'allongement à force maximale Art de la première structure (10) selon la première direction générale (G1) vérifie: Art > (2π x H) / L dans lequel H0 x K ≤ H avec H0 la distance droite moyenne entre une face interne (42) de la première structure (10) et une face interne (46) de la deuxième structure (12) lorsque chaque portion filaire porteuse (74) est au repos et K=0,50.
