To provide a folding-completion body of a head protection airbag capable of arranging a compactly storable compression part by restraining impartment of influence to an expansion state.SOLUTION: A folding-completion body of a head protection airbag comprises a compression part 74 compressed so as to reduce a cross-sectional shape after folding up a head protection airbag 20 inflatable so as to cover the car inside of windows W1 and W2 of a vehicle V by making inflation gas flow in so that the lower edge 21b side is approached to the upper edge 21a side from a flatly expanded state so as to be storable on the upper edge side of the window and an uncompressed non-compression part 71. The airbag comprises a shield inflation part 24 for covering the car inside of the window when completing inflation. The shield inflation part comprises a primary expansion area 26 for expanding-inflating at the beginning of inflow of the inflation gas and a secondary expansion area 27 arranged on one end 21c side in the longitudinal direction of the airbag so as to be expandable-inflatable by following up the primary expansion area. The secondary expansion area 27 is arranged in the compression part 74, and the primary expansion area 26 is arranged in the non-compression part 71.SELECTED DRAWING: Figure 10
【課題】展開状態に影響を与えることを抑えて、コンパクトに収納できる圧縮部を配設させることが可能な頭部保護エアバッグの折り完了体を提供すること。【解決手段】膨張用ガスを流入させて車両Vの窓W1,W2の車内側を覆うように膨張可能な頭部保護エアバッグ20を、窓の上縁側に収納可能に、平らに展開した状態から下縁21b側を上縁21a側に接近させるように、折り畳んだ後、断面形状を小さくするように圧縮される圧縮部74と、圧縮されない非圧縮部71と、を備える。エアバッグは、膨張完了時に窓の車内側を覆う遮蔽膨張部24を備える。遮蔽膨張部は、膨張用ガスの流入当初に展開膨張する一次展開エリア26と、一次展開エリアに追従して展開膨張可能としてエアバッグの前後方向の一端21c側に配設される二次展開エリア27と、を備える。二次展開エリアは27は、圧縮部74に配設され、一次展開エリア26は、非圧縮部71に配設される。【選択図】図10
