A lateral tilting device for a patient lying on a mattress is capable of being inserted between the mattress and a level bed base or bed frame on which the mattress rests. The lateral tilting device comprises at least two independent first and second inflatable cells, pneumatically independent and positioned at least partly symmetrically from one another in relation to a median axis of the tilting device. The lateral tilting device includes two ‘U’ shaped inflatable compartments that are fitted into one another. A method for the lateral tilting of the mattress includes inflating a said first or second cell and concomitant deflation of the other second or respectively first cell of the tilting device laid out under the mattress.

1. A lateral tilting device for tilting a patient, the lateral tilting device comprising first and second inflatable cells, pneumatically independent, and positioned at least partly symmetrically to one another in relation to a median axis of said tilting device, wherein each of the first and second inflatable cells are U-shaped and fitted into one another such that a portion of each of the first and second inflatable cells is nested within the U-shape of the other of the first and second cells without the first and second inflatable cells overlapping, wherein a first lateral incline of the mattress is created when the first cell is inflated more than the second cell and a second lateral incline with a slope in an opposite direction to that of the first lateral incline when said second cell is inflated more than said first cell, and wherein the median axis intersects each of the first and second inflatable cells. 2. The lateral tilting device of claim 1, wherein each cell of the first and second inflatable cells comprises two compartments with longitudinal shape, the two compartments of each said cell of the first and second inflatable cells being shaped such that each compartment of said first and second cells closest to the median axis of said tilting device have a lower height than that of the other compartment of the same cell of the first and second inflatable cells in the inflated state. 3. The lateral tilting device of claim 2, wherein said first and second inflatable cells extend over a length of at least 1.5 meters. 4. The lateral tilting device of claim 2, wherein the compartments of greater height and the compartments of lesser height of each of said first and second inflatable cells are located on either side of said longitudinal median axis of the lateral tilting device. 5. The lateral tilting device of claim 2, wherein the two compartments of each of the first and second inflatable cells communicate between each other pneumatically. 6. The lateral tilting device of claim 2, wherein the respective height of each said first and second inflatable cells in the maximum and respectively minimum inflation state permits said first and second lateral inclines of about 20° to about 25°. 7. The lateral tilting device according to claim 1, wherein the first and second inflatable cells are joined to one another. 8. The lateral tilting device of claim 7, further comprising means of inflation-deflation including at least one pump, inflation-deflation orifices of said first and second inflatable cells and means of independent pneumatic communication between said pumps and said orifices, and said means of inflation-deflation comprising an automatic electronic regulating device for alternate inflation-deflation of the first and second inflatable cells capable of controlling the inflation of one cell and concomitant deflation of the other cell and successive inflation, then deflation of each said first and second inflatable cell according to cycles of different durations, with time durations for maintaining the inflated state of each cell and maintaining the deflated state from about 30 seconds to about 4 hours. 9. The lateral tilting device according to claim 7, wherein the first and second inflatable cells are joined mechanically to one another by heat-sealing lines of two sheets comprising plastic material, one against the other, or a sheet comprising plastic material folded onto itself, said heat-sealing lines forming the at least two compartments of the first and second inflatable cells. 10. The lateral tilting device according to claim 1, wherein said first and second inflatable cells comprise a plastic material including at least one of PVC or PU (polyurethane). 11. The support device of claim 1, wherein the each of the first cell and the second cell is formed to include a first branch, a second branch spaced apart from and extending parallel to the first branch, and a transversal junction area extending between and interconnecting the first branch and the second branch, and the transversal junction area of the first cell is spaced apart from the transversal junction area of the second cell. 12. A support device comprising a mattress capable of supporting a patient in a lying position, anda lateral tilting device for tilting a patient, the lateral tilting device comprising first and second inflatable cells, pneumatically independent, and positioned at least partly symmetrically to one another in relation to a median axis of said tilting device, wherein each of the first and second inflatable cells are U-shaped and fitted into one another such that a portion of each of the first and second inflatable cells is nested within the U-shape of the other of the first and second cells, wherein a first lateral incline of the mattress is created when the first cell is inflated more than the second cell and a second lateral incline with a slope in an opposite direction to that of the first lateral incline when said second cell is inflated more than said first cell, wherein the median axis intersects each of the first and second inflatable cells, the tilting device being situated under the mattress, said first and second inflatable cells each including a pair of compartments extending in a longitudinal direction of the mattress,wherein the first and second inflatable cells are located entirely within the footprint of the mattress when viewed from above. 13. The support device of claim 12, wherein each of the first and second cells are nested within the U-shape of the other of the first and second cells without overlapping the other of the first and second cells. 14. A method of lateral tilting of a support device according to claim 12, wherein the tilting of said mattress is produced by inflation of one of said first and second inflatable cells and concomitant deflation of the other of said first and second inflatable cells of said tilting device laid out under said mattress. 15. The method of claim 14, wherein an inflation-deflation cycle of each said first and second inflatable cell is realized successively to produce the lateral tilts of said mattress alternately of each side, by laterally inclining the mattress by about 4° to about 8° tilt, with said first and second inflatable cells being inflated to a regulated pressure. 16. The support device according to claim 12, wherein said mattress comprises a plurality of pneumatically independent inflatable transversal cells extending in a direction perpendicular to the longitudinal direction of the mattress and side by side in the longitudinal direction of the mattress, the pressure within said transversal cells being capable of being regulated by means of inflation-deflation and electronically according to the air pressure values measured in the cells and the position and/or penetration of a patient into said mattress as determined by a sensor inserted between said mattress and said tilting device. 17. The support device of claim 16, wherein said mattress of said transversal cells rests on a lower mattress comprising air filled cells, said tilting device being situated beneath said lower mattress.
