<P>PROBLEM TO BE SOLVED: To provide a seat back board and a vehicle seat using the same, that can restrain stress concentration by an input load to a resin spring part. <P>SOLUTION: In this seat back board 16, a lower side board side part 50 integrally connected to a back board part 36 is fixed to a side frame 26 by a clip 65. In a lower side back spring body part 48, though a spring general part 48A is arranged on the seat back rear side more than the clip 65, a front extending part 48B is connected to the lower side board side part 50 in a connecting part 53 on the seat back front side more than the spring general part 48A. Thus, since a distance up to the clip 65 from the connecting part 53 can be shortened more than when the connecting part 53 is juxtaposed in the seat back width direction to the spring general part 48A, stress concentration on the periphery of the connecting part 53 by the input load P to the lower side back spring body part 48, can be restrained. <P>COPYRIGHT: (C)2013,JPO&INPIT |
