PROBLEM TO BE SOLVED: To contribute to improving efficiently occupant holding performance of a side support part of a seat back when predicting a side collision or an oblique collision.SOLUTION: A vehicular seat 10 comprises: left and right bladders 45 which are provided in left and right side-support parts 12B of a seat back 12 and inflate and deflate in the left and right side-support parts 12B by supply and exhaust of air; left and right support panels 56 which are provided in a shell frame 14 (a seat back frame) and support the left and right bladders 45 from outside in a seat width direction; left and right movable panels 48 which are provided inside in the seat width direction of the left and right bladders 45 in the left and right side support parts 12B and are displaced in the seat width direction by inflation and deflation of the left and right bladders 45; and an inflation enhancer 78 which when predicting a side collision or an oblique collision, enhances inflation in one site (a bladder 74 for collision) of the left and right bladders 45 more than in the other site (a bladder 46 for adjustment).SELECTED DRAWING: Figure 2 |
