Personal protection device

A personal protection device for protection of a portion of the body of a user, said device comprising an inflatable member intended to protect at least partially a zone of the body of the user, including at least a first portion and a second portion, wherein:

• the first portion and the second portion are superimposed in a corresponding overlapping area or superimposition area, and a height or thickness of at least one, or each, of the first portion and the second portion is, in the overlapping area or superimposition area, smaller than a height or thickness of a remaining part of the inflatable member, the remaining part being a non-overlapping zone located adjacent to the overlapping area;
• the inflatable member includes two adjacent textile structures connected to each other, a first textile structure is included in one, or each, of the first portion and the second portion and a second textile structure is included in the remaining part of the inflatable member, and a height of the first textile structure is smaller than a height of the second textile structure;
• and
• each textile structure includes pairs of opposite meshes and a plurality of tie members positioned between the meshes, the tie members having ends stably associated with surface portions of said meshes, said tie members have dimensions so that, when said inflatable member is in a deflated rest condition, said tie members are in a non-tensioned condition collapsed inside the inflatable member, and when said inflatable member is in an inflated condition, said tie members are subjected to tensile stress, and the height of the respective textile structure depends on the length of said tie members.
