  • body pressure is concentrated on the buttocks and the back if the repulsive force of the mat is uniformly high, so that the buttocks and the back are likely to become congested. As a result, there is a lot of tossing and turning in order to relieve congestion, so sleep tends to be light.

Therefore, in this configuration, the stepped portion of the serratus posterior superior muscle is formed in a range located between the spine and the scapula of each of the pair of serratus posterior superior muscles, thereby pulling up the rib group in the serratus posterior superior muscle.

Abstract

L'invention concerne un matelas (1) qui peut faciliter la respiration en décubitus dorsal. Le matelas (1) comprend une section de support dorsal (3). La section de support dorsal (3) est disposée sous une région correspondant à au moins une partie de chaque paire de muscles dentelés postérieurs et supérieurs gauche et droit d'une personne en décubitus dorsal, et comprend : une paire de parties étagées de muscles dentelés postérieurs et supérieurs (19) qui est encastrée sous une surface de référence (100) de la section de support dorsal (3) ; et une paire de supports d'omoplate (20) qui soutiennent une région correspondant à la paire d'omoplates gauche et droite d'une personne en décubitus dorsal. La paire de supports d'omoplate (20) comporte des supports inférieurs (21) qui soutiennent une région correspondant à la partie de l'omoplate inférieure aux muscles dentelés postérieurs et supérieurs, la région étant soutenue à une position située à la hauteur de la surface de référence (100) ou au-dessus de celle-ci. Les supports inférieurs (21) sont configurés pour être surélevés par rapport aux parties des supports de l'omoplate (20) qui sont supérieures aux parties des supports inférieurs (21).
