To provide a side airbag device and a side airbag manufacturing method which inhibit a rib of an occupant from deflecting upon inflation and deployment of a side airbag, and which can improve performance for protecting the occupant.SOLUTION: A side airbag device 100 has a side airbag 108 that receives the supply of gas, thereby inflating and deploying between a vehicle seat 102 and a side door 106. The side airbag includes a first fold line 112 provided so as to descend from the back of an occupant 118 toward the front, along a longitudinal direction of an upper arm 120 of the occupant properly sitting on the vehicle seat, when viewed in a lateral direction of a vehicle. The first fold line overlaps the upper arm upon inflation and deployment. The side airbag is divided into: a first area 114 which is located above the first fold line upon inflation and deployment; and a second area 116 which is located below the first fold line, and in which an inflator 110 is stored. The first area receives the supply of gas later than the second area, and inflates and deploys later than the second area.SELECTED DRAWING: Figure 3

    【課題】サイドエアバッグの膨張展開時に乗員の肋骨の撓みを抑え、乗員保護性能を向上できるサイドエアバッグ装置およびサイドエアバッグ製造方法を提供することを目的としている。【解決手段】サイドエアバッグ装置100は、ガスの供給を受けて車両用シート102とサイドドア106との間で膨張展開するサイドエアバッグ108を有し、サイドエアバッグは、車両側方から見て、車両用シートに正規に着座した乗員118の上腕120の長手方向に沿って乗員の後方側から前方方向に向けて下降するように設けられ、上腕に膨張展開時に重なる第1折り畳みライン112を含み、サイドエアバッグは、膨張展開時に第1折り畳みラインよりも上側に位置する第1領域114と、第1折り畳みラインよりも下側に位置しインフレータ110が収容された第2領域116とに区分され、第1領域は、第2領域よりも遅れてガスが供給され、第2領域に遅れて膨張展開する。【選択図】図3
