A method for manufacturing a protection device to be worn by a user, the method comprising:
- knitting an inflatable three-dimensional unitary knitted body having an inner chamber that is configured to assume an inflated condition for protection of the user, and a deflated condition at rest, the inflatable three-dimensional unitary knitted body being knitted by a rectilinear knitting machine, wherein:
- in the inflated condition, the inner chamber is defined by at least a partially tubular shape;
- in the deflated condition, the inner chamber is defined by overlapping opposite regions of said inflatable three-dimensional unitary knitted body;
- and
- the knitting comprises forming a plurality of union threads in said inflatable three-dimensional unitary knitted body by said rectilinear knitting machine, the plurality of union threads occupying the inner chamber and connecting the overlapping opposite regions.
