A bed plane with improved structure, comprising a plurality of slats, arranged transversally to the frame (10) of the bed and connected to it through slat- holders, includes a series of stems or pistons (11), each connected with one or more of the aforementioned slats and associated with a respective spring (12) for vertical sliding; each piston carries a pulley or sliding guide (15) for the transmission of motion, which occurs thanks to flexible members (16), such as cords, belts, chains and cables, fixed to the frame (10) of the bed plane. The pistons (11), connected to the slats, react to the pressures exerted by the body lying down on the bed plane, compensating for the sinking created by the heaviest parts of the body, i.e. those parts between the shoulders and the pelvis, with an upward thrust, supporting the lighter parts, in other words the back and kidneys.

L'invention concerne un plan de lit avec une structure améliorée, comprenant une pluralité de lattes disposées de manière transversale par rapport au cadre (10) du lit et connectées à celui-ci au moyen de supports de lattes. Ledit plan comprend une série de tiges ou de pistons (11) connectés chacun à une ou plusieurs desdites lattes et associés à un ressort correspondant (12) de manière à glisser verticalement. Chaque piston comporte une poulie ou guide coulissant (15) pour la transmission d'un mouvement se produisant grâce à des éléments flexibles (16), par exemple des cordes, des courroies, des chaînes et des câbles, fixés au cadre (10) du lit. Les pistons (11), connectés aux lattes, réagissent aux pressions exercées par un corps étendu sur le lit, compensant l'enfoncement créé par les parties les plus lourdes du corps, c'est-à-dire les parties situées entre les épaules et le bassin, par une orientation vers le haut supportant les parties les plus légères, c'est-à-dire le dos et les reins.
