Inflatable lifejacket comprises neck portion and branches extending around torso with welded connection zones which control deformation during inflation to define hollow portions

摘要

An inflatable bladder (2) arranged in a protection casing comprises a neck portion (3) which passes around the user's neck and branches (5) which extend along the user's torso. In the branches are welded portions (7) for controlling deformation during bladder inflation so as to define, once inflated, hollow portions (8) enabling the branches to fit the profile of the use's torso.
