In an occupant protection device, an airbag disposed in a region of a lap belt of a seat belt includes a bag body and a conduit connected to an inflator disposed near a lower end of a seat portion of a seat. The airbag is held by the lap belt in a folded state. The conduit is disposed substantially along the lap belt while being held by a conduit holder. The conduit holder is formed of a material having flexibility and higher rigidity than the conduit, is disposed substantially along the conduit, and has both end sides fixed to a seat side and a bag body side, respectively, by a seat-side fixing portion or a bag body-side fixing portion.

An airbag comprises: first and second fabric panels; a seam at a seam area of the first and second fabric panels, the seam joining the first and second fabric panels to each other; and a sacrificial elastomer line at a location inward of the seam area, the sacrificial elastomer line joining the first and second fabric panels to each other at the location.

A restraint system of a vehicle having a roof and a cabin with a seat for an occupant includes an inflator mounted to the roof of the vehicle and an airbag communicatively coupled to the inflator and inflatable to a deployed position from a stored position. The airbag comprising a main body comprising a first side that faces an upper half of an occupant, a second side that faces a lower half of the occupant, a first end coupled to the first and second sides, and a second end coupled to the first and second sides. The airbag further comprising a first tube communicatively coupled to the inflator and the main body between the first end and the second end and a second tube communicatively coupled to the inflator and the main body between the first end and the second end.

Provided are an addition-curable liquid silicone rubber composition having exceptional adhesiveness and adhesive durability in a silicone rubber coating layer with respect to an airbag fabric, and an airbag. An addition-curable liquid silicone rubber composition for airbags having, as essential components: (A) an organopolysiloxane having a weight-average degree of polymerization of 100-2,000 and containing two or more silicon-atom-bonded alkenyl groups per molecule; (B) an organohydrogenpolysiloxane containing at least two silicon-atom-bonded hydrogen atoms per molecule; (C) a silica fine powder having a BET specific surface area of 50 m.sup.2/g or higher; (D) a catalyst for a hydrosilylation reaction; (E) an organic compound including at least one functional group selected from alkenyl groups, alkoxysilyl groups, and hydrosilyl groups, and at least one isocyanate group, per molecule; and (F) a condensation catalyst selected from organic titanium compounds, organic zirconium compounds, and organic aluminum compounds.
