CA 2382179

A body support apparatus, for example a bed, comprises a support surface defined by support members (5, 24, 25, 28). Each support member is mounted for movement in a direction substantially normal to the support surface. Support members are so arranged that movement of any one of the support members in a direction substantially normal to the support surface and beyond a threshold distance relative to an adjacent support member causes movement in substantially the same direction of said adjacent support member. No movement of a support member is caused by the movement of an adjacent support member when the distance of relative movement is below the threshold distance. The support members are resiliently urged towards an unloaded position, by means of tension springs (7).

L'invention concerne un appareil de support du corps, par exemple un lit, qui comprend une surface de support définie par des éléments de support (5, 24, 25, 28). Chaque élément de support est monté de façon à se déplacer dans une direction sensiblement normale par rapport à la surface de support. Les éléments de support sont disposés de sorte qu'un mouvement de n'importe lequel d'entre eux dans une direction sensiblement normale par rapport à la surface de support, dépassant une distance seuil par rapport à un élément adjacent de support entraîne un mouvement dudit élément de support sensiblement dans la même direction. Aucun mouvement d'un élément de support n'est occasionné par le mouvement d'un élément de support adjacent lorsque la distance du mouvement relatif est inférieure à la distance seuil. Les éléments de support sont poussés de façon élastique vers une position non chargée, au moyen d'un ressort de tension (7).
