PROBLEM TO BE SOLVED: To stabilize deploying direction in a side airbag capable of restraining at least from a belly part to a shoulder part of an occupant.SOLUTION: In a vehicular seat 10, a side airbag 36 of a side airbag device 30 passes through a vertical slit portion 64A of a seat back pad 18 during expansion/deploying, thereby breaking a burst line portion 34 of a seat back skin 20. The vertical slit portion 64A positions an upper end 64A1 on a seat back rear side with respect to a lower end 64A2. Therefore, in the side airbag 36, a part passing through the upper end 64A1 side is expanded/deployed from the seat back rear side compared with a part passing through the lower end 64A2 side. Consequently, in the side airbag 36, difference in deploying directions in a plane view, in the part passing through the upper end 64A1 side and expanding/deploying to a side part of a shoulder portion, and in the part passing through the lower end 64A2 side and expanding/deploying to side parts of a chest portion and a belly portion, can be decreased. Therefore, adjustment in the deploying direction of the side airbag 36 is facilitated.SELECTED DRAWING: Figure 4

    【課題】乗員の少なくとも腹部から肩部までを拘束可能なサイドエアバッグにおける展開方向の安定化に寄与する。【解決手段】車両用シート10では、サイドエアバッグ装置30のサイドエアバッグ36が、膨張展開時にシートバックパッド18の上下スリット部64Aを通り、シートバック表皮20のバーストライン部34を破断させる。上下スリット部64Aは、上端64A1が下端64A2よりもシートバック後方側に位置している。このため、サイドエアバッグ36において、上端64A1側を通る部位が、下端64A2側を通る部位よりもシートバック後方側から膨張展開する。その結果、サイドエアバッグ36において、上端64A1側を通って肩部の側方に膨張展開する部位と、下端64A2側を通って胸部及び腹部の側方に膨張展開する部位とにおける、平面視での展開方向の相違を小さくできる。これにより、サイドエアバッグ36の展開方向の調整が容易になる。【選択図】図4
