A life jacket 1 that includes a collar 2 that is intended to be positioned behind the head of the wearer during use, and a main body 3 attached to two lateral extremities 4 of the collar 2. The life jacket includes positioning resources 5 designed to pass the collar 2 from a down position (Figure 2), in which it is intended to rest upon the top of the back of a wearer, to an up position (Figure 3), in which it is intended to rest behind the head of the wearer. The positioning resources include elastic tensioning resources 7 and a hinge 12 to provide a pivoting connection between the collar and the main body. |
