  "textContent": "The present invention relates to a vehicle seat back which comprises a seat back pad. An opening portion is disposed at a front portion of the seat back pad where a backrest surface is formed for a seated person. A plurality of independent rod-like or plate-like supports, which are formed of a synthetic resin foam having a bending deflection measured according to a method described in JIS K7221-2:2006 of at least 20 mm and having a load at a 20 mm deflection of between 2 N and 100 N, are fixed to a seat frame or a circumferential edge portion of the opening portion, or integrally molded with the circumferential edge portion of the opening portion, in a bridging direction between opposing edge portions forming the opening portion and in the form of a single-point support or multi-point support. The seat pad is a structure which has a shape in which the plurality of supports are arrayed at predetermined intervals. The vehicle seat back of the present invention comprises a void portion which enables bending deformation of the support toward a rear portion of the support, and therefore weight can be reduced, and cushioning properties, fit, and recyclability can be improved.",
