PROTECTION DEVICE

A protection device (1, 100) for the personal protection of a user is described. The protection device comprises an inflatable element (2, 102). The inflatable element (2, 102) defines an internal chamber (3, 104) apt to receive an inflation fluid and it is apt to assume an active inflated condition and a rest deflated condition in case of fall of a user, in case of danger or impact of a user against an obstacle. A first portion (18, 103a) of the inflatable element (2, 102) has the ability to assume, in inflated condition, a certain surface extension, or an ability to occupy, in inflated condition, a determined area, or a different expansion capacity compared to a corresponding capacity of an opposite portion (19, 103b) of the inflatable element (2, 102).
