Inflatable safety helmet, specially for motorcycling

A safety helmet, comprising an envelope (1) adapted to conform to the shape of a human head,

• an inner air chamber (3) surrounding and connected to said envelope,
• an outer air chamber (2) surrounding and connected to said inner air chamber,
• an inner partition (4) separating said inner and outer air chambers,
• a one-way valve (9), said outer air chamber communicating to said inner air chamber through said one-way valve such that air from said outer air chamber can flow into said inner chamber,
• an inflating device (5) directly communicating with said outer chamber, said inflating device including means adapted to inflate said outer air chamber and said inner air chamber, said inner air chamber being adapted to stay inflated in the event that said the outer air chamber accidently deflates,
• first and second complementary members (7, 8), said first complementary member (7) being joined to said inflating device via first coupling means, said second complementary member (8) being attached to an outer wall of said outer air chamber via second coupling means, said envelope being adapted to fit within said complementary members when said inner and outer chambers are in a deflated condition, such that said two complementary members can form a box (6) for storage,
• one of said complementary members (7) being joined to said inflating device, and said other member (8) being connected on an opposite side of said helmet to said outer air chamber, both of said complementary members being provided with coupling means so that they can be joined together, leaving an inner space in which to keep said envelope.
