The vehicle seat includes a seat back frame made of a light alloy and formed into a substantially quadrilateral shape, the seat back frame comprising an upper section, left and right side sections, and a lower section, an airbag module provided at one of the left and right side sections, the airbag module being adapted to be enclosed by stay cloths which are sewn at one terminals thereof together with terminals of front and side portions of a trim cover, first and second retainer members secured to the side section for retaining the other terminals of the stay cloths, the first and second retainer members including applying plate portions, the applying portion of the first retainer member being applied onto one surface of the side section, the applying portion of the second retainer member being applied onto the other surface of the side section, bolts penetrating the applying portion of the first retainer member, the side section, and the applying portion of the second retainer member, and nuts mounted on the bolts, so that the first and second retainer members are fastened together to the side section so as to be interpose the side section therebetween.

Claims

1. A vehicle seat comprising:

a seat back frame made of a light alloy and formed into a substantially quadrilateral shape;

said seat back frame comprising an upper section, left and right side sections, and a lower section;

a cushion supported on said seat back frame;

an airbag module provided at one of said left and right side sections;

a trim cover for covering said cushion;

first and second stay cloths for enclosing said airbag module;

said first and second stay cloths being sewn at one terminals thereof to said trim cover;

first and second retainer members secured to said one of said side sections of said seat back frame for retaining the other terminals of said first and second stay cloths;

said first retainer member comprising a first main body having a substantially C-shape and first applying plate portions projecting laterally from both edges of said first main body;

said first applying plate portions of said first retainer member being applied onto one surface of said one of said side sections of said seat back frame;

said second retainer member comprising a second main body and a second applying plate portion;

said second main body being formed into a substantially C-shape by bending a metal wire such that said second main body has a corrugated shape and said second main body being attached to said second applying plate portion;

said second applying plate portion being applied onto the other surface of said one of said side sections of said seat back frame;

bolts penetrating said first applying plate portions of said first retainer member, said side section of said seat back frame, and said second applying plate portion of said second retainer member; and

nuts mounted on said bolts, so that said first and second retainer members are fastened together to said side section of said seat back frame so as to interpose said side section of said seat back frame therebetween;

said first stay cloth being fixed at the other terminal thereof to said first main body of said first retainer member, and said second stay cloth being fixed at the other terminal thereof to said second main body of said second retainer member, to thereby enclose said airbag module.

2. A vehicle seat according to claim 1, wherein said second applying plate portion has a plurality of parallel elongated-projections.

3. A vehicle seat according to claim 2, wherein said elongated-projections are formed by causing regions of said second applying plate portion to be embossed.
