DETAILED DESCRIPTION

[0016] With reference to the figures, the bed according to the invention is generally designated with the reference numeral 10.

[0017] The bed is of the type that can be articulated and comprises a plurality of sections 11 which correspond to the regions of the back, buttocks, thighs and legs of the in-patient.

[0018] In particular, one of the sections 11, the one that corresponds to the buttocks region, has at least a portion 12 thereof which is movable and articulated to the section 11 of the backrest 13.

[0019] FIG. 1 and FIG. 2 show the bed 10 in a flat configuration, in which both the portion 12 and the backrest 13 are arranged according to the lying surface.

[0020] Below the lying surface, at the portion 12, there is a curved element 14 which extends from the lying surface downwardly. When the backrest 13 is lifted, as in the configurations shown in FIGS. 3 to 6, the portion 12 is translated, exposing the curved element 14 and, by inclining thereon, contributes with it to form a cradle 15 for the buttocks region.

[0021] FIG. 3 and FIG. 4 show the bed 10 with the backrest 13 inclined by approximately 40°, while in the subsequent FIGS. 5 and 6 the backrest 13 is inclined by approximately 70°. By comparing these two configurations, it can be seen that the cradle 15 is deeper for greater inclinations of the backrest 13.

[0022] In the lateral sections shown in FIGS. 2, 4 and 6 the bed 10 is covered by a mattress 16 of adapted shape and characteristics and thereon the shape 17 of a human being is shown, in order to show the positioning of the body on the sections of the bed 10, and in particular at the cradle 15.

[0023] As can be seen from the figures, the backrest 13 can rotate during lifting and lowering and is translatable toward the headboard, and the portion 12 is pivoted thereto, about a corresponding pivoting axis 18 which is transverse to the main direction of extension of the bed 10, and on the opposite side with respect to the pivoting side it is free and rests against the curved element 14.

[0024] As the portion 12 is pivoted to the backrest 13, it is entrained by it in retraction toward the headboard, revealing the curved element 14.

[0025] In the exemplary bed 10 shown, the backrest 13 comprises a lumbosacral portion 19 which is narrower than the resting surface of the bed 10, and to which the portion 12, which is also narrower, is pivoted. In this manner the cradle 15 is substantially delimited not only in length but also in width.

[0026] As shown in the figures in cross-section, the backrest 13 is conveniently movable by way of a kinematic mechanism 20, conventional, which is associated with actuation means 21, which, as illustrated, can consist of actuators, preferably electric.

[0027] The bed 10 is also provided with means of translation of the backrest 13 upwardly, which are adapted to act during the rotation thereof

[0028] Use of the bed, according to the invention, is the following.

[0029] The bed 10 can be used in the flat configuration for the in-patient to rest in the supine position, or it can be brought to a configuration whereby the backrest 13 is inclined, passively shifting the in-patient to a sitting position.

[0030] In this case, one acts in a known manner, for example by way of a keypad, on the actuation means 21, which activate the kinematic mechanism 20 capable of lifting the backrest 13.

[0031] While the backrest 13 rotates, being lifted at the end where the head is rested, at the same time it is made translate toward the headboard, entraining with it the portion 12 which is pivoted thereto, which is therefore capable of assuming a different inclination from that of the backrest 13.

[0032] In moving back toward the headboard, the portion 12, which rests against the curved element 14 on the opposite side with respect to the pivoting side, inclines progressively, on the curved element 14, forming together with the latter the cradle 15 for the buttocks region, as illustrated with the shape 17.

[0033] It should be noted that in this manner the distance indicated with X in FIGS. 2, 4 and 6, which is the distance between the foot of the in-patient and the end of the mattress 16 at the footboard end, remains constant during the movement of the backrest 13.

[0034] The cradle 15 has in fact a resting surface with a curvature extending below the lying surface, on which the legs rest, thus preventing the body of the in-patient from sliding toward the footboard.

[0035] The initial thrust toward the footboard, owing to the movement of the backrest 13, is immediately limited by the simultaneous retraction toward the headboard, while, according to the above explanation, the slipping of the in-patient who is now in the sitting position is prevented by the presence of the cradle 15.

[0036] In this manner the patient does not have to be continuously repositioned and posture is improved.

[0037] In practice it has been found that the invention fully achieves the intended aim, by providing a bed for hospital stays which is capable of preventing the slipping of the in-patient toward the footboard when the backrest is inclined, and is therefore also more comfortable for the time the patient remains in the sitting position.

[0038] The invention, thus conceived, is susceptible of numerous modifications and variations, all of which are within the scope of the appended claims. Moreover, all the details may be substituted by other, technically equivalent elements.

[0039] In practice the materials employed, provided they are compatible with the specific use, and the contingent dimensions and shapes, may be any according to requirements and to the state of the art.
