An inflatable air-belt comprises an air tube and a sheath surrounding the air tube. While the sheath has a flat strip shape when the air-belt is used as an usual flat belt, the air tube is inflated when a predetermined impact is applied to a sensor for the air-belt. The air tube may be folded toward its center along its both sides. The sheath may be formed with cut perforated lines along its both sides. The sheath may comprise two flat strips which are attached to each other by means of hook-loop fastener attached to longitudinal edges of the flat strips. The air-belt is provided at its middle portion with a locking buckle assembly for securing the middle portion of the air-belt to the vehicle body. The locking buckle assembly has a locking buckle fixed to the vehicle body and a buckle tongue connected to the air-belt. The buckle tongue is formed with a breakable portion defined by a perforated line extended from both ends of hole thereof such that the perforated line extended from both ends of hole thereof such that the breakable portion is removed to form an enlarged hole by inflation of the air-belt at the time of collision.
An inflatable air-belt for a vehicle safety system comprising an air tube made of common material and communicated with an air tank and adapted to be positioned about an occupant and to be inflated by a pressurized gas in the air tank to protect the occupant against shock at the time of collision, which is fixed to connecting pieces at one end and connected fixed to a reel device at the other end thereof, and passed through an elongated hole of a buckle tongue coupled to a locking buckle for securing a portion between both said ends of said air belt,
