Abstract
(EN)
This invention relates to a bed mat. A mat main body comprises a core material (3) made of a rigid foamed material having a sufficient thickness, protective sheet members (4), (5) placed on the front and reverse surfaces of the core material while sandwiching the core material (3) between them and surface layer materials (6), (7) made of a cushion material and put on the protective sheet material (4), (5). At least one of the surface layer materials (6), (7) is formed by superposing a second cushion layer (11) made of a semi-rigid cushion material having a corrugated surface (13) on its surface on a first cushion layer (10) made of a soft cushion material. A conventional bed mat has a structure incorporating a plurality of coil springs fixed to a metal frame, and is not free from problems that the total weight is heavy and the mat is difficult to handle. In accordance with the present invention, the rigid foamed material is used as the core material (3) without using the metal member. Therefore, the mat of the present invention is light in weight and is free from problems such as rust and breakage. Moreover, since the corrugated surface (13) of the second cushion layer (11) in the surface layer material supports the body in a point contact state, air permeability is high and finger-pressure action is provided to promote health.

L'invention se rapporte à un matelas, dont le corps principal est constitué par un matériau intérieur (3) en mousse rigide d'une épaisseur suffisante, par des couches protectrices (4, 5) placées sur la surface du dessus et sur la surface du dessous du matériau intérieur (3) qu'elles prennent en sandwich, ainsi que par des couches superficielles (6, 7) composées d'un matériau élastique du type coussin et placées sur la couche protectrice (4, 5). Au moins l'une des couches superficielles (6, 7) est formée par superposition d'une seconde couche du type coussin (11) en matériau du type coussin semi-rigide, dont la surface présente un profil ondulé (13), sur une première couche du type coussin (10) en matériau du type coussin mou. Les matelas classiques ont une structure dans laquelle sont incorporés plusieurs ressorts spiralés fixés à une structure métallique et présentent des problèmes tels que poids total élevé et difficulté de manipulation. Selon la présente invention, le matériau en mousse rigide sert de matériau intérieur (3) sans utilisation de l'élément métallique. Le matelas de la présente invention est par conséquent d'un poids léger et ne présente pas les inconvénients notamment de sa facilité à rouiller et à se casser. En outre, étant donné que la surface ondulée (13) de la seconde couche du type coussin (11) de la couche superficielle soutient le corps par des contacts ponctuels, la perméabilité à l'air est élevée et la pression par points que cette couche exerce a une action bénéfique pour la santé.
