<p>The adjustable electrobed includes:… a) A head supported by the spring-mattress, comprising two independent elements which can adopt different height <<V>>-positions by means of a electromotor. Each element comprises two superposed plates, the upper one being capable of displacement.… b) A spring-mattress comprising two rigid bodies, being hinged at the paracentral area, supported by three pair of legs with damping means. The hinging is achieved by braces being crossed by small-spindles operated by electric motors. The hinging comprises a plurality of accordioned hinges, the turn being carried out by a pre-selected one, as the rest of them rigidly set at the corresponding spring-mattress body. The lower body includes a roller for the bedclothes to be used.… c) A platform for supporting the legs.… d) A pneumatic mattress, the elasticity of which can be adjusted, related to a pneumatic damper for adaptation to the user's weight. …<??>The mattress has a transversal slot which connects with the one provided in the spring-mattress.</p> |
