Inflatable lifejacket comprises neck portion and branches extending around torso with welded connection zones which cause their deformation during inflation to define articulation zones

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. Between the connection zones of the neck portion and branches are welded portions (11) for deforming these during bladder inflation so as to define, once inflated, articulation zones between the branches and the neck portion.
