Support device of the mattress type comprising a heterogeneous inflatable structure
First Claim
1. A mattress device comprising, inside at least one outer casing:
- at least one inflatable top layer made up of a plurality of adjacent elements that are secured together and that are individually inflatable with a fluid via a pneumatic inflation and pressure regulation device;
at least one bottom layer supporting said top layer and provided with a recess; and
a penetration and/or pressure sensor received in the recess and connected to said pneumatic inflation and pressure regulation device, said sensor making it possible to determine the penetration and/or the pressure applied locally by the body of an individual bearing against the inflatable top layer and to regulate the inflation pressures of said elements of said top layer correspondingly;
wherein, in a substantially central support zone designed to support the sacrum zone of the individual'"'"'s body, said top layer is made up of a plurality of inflatable elements that are individualized in unitary manner, and that are each of a width smaller than their height for better preservation of the skin tissue, the width of said individualized inflatable elements of said central support zone being smaller than a width of each of the inflatable elements of opposite end zones situated adjacent to opposite ends of said central support zone;
wherein said sensor, said recess, and said central support zone are of substantially equivalent length along a long dimension of the mattress device.

Abstract
A mattress has at least one inflatable top layer made up of a plurality of adjacent elements that are individually inflatable by a pneumatic inflation and pressure regulation device and at least one bottom layer supporting the top layer. The bottom layer has a recess for receiving a sensor connected to the pneumatic inflation and pressure regulation device, and making it possible to determine the pressure applied by the body of an individual bearing against the inflatable top layer and to regulate the inflation pressures of the elements of the top layer. In at least one support zone designed to support the sacrum of an individual, the top layer is made up of a plurality of inflatable elements that are of a width smaller than their height.
