PROBLEM TO BE SOLVED: To suppress a deformation amount of a back pad compressed by a band body to be deformed so as to retain an appearance of a seat back.SOLUTION: There is provided an attaching structure for attaching a webbing 34 cleaved at a sewing part 80 at an end part of a first belt shape member 70 and an end part of a second belt shape member 72 upon a back pad 32 breaks along with development of a side air back 20 to a back frame 30 via brackets 82, 100. An end part of the belt shape member is connected to one end part of the bracket. The bracket is fastened to the back frame with bolts on long holes 88, 104 formed on the other end part of the bracket. At that time, the bracket is inclined relatively to an attachment surface of the back frame and shaft parts of the bolts are inserted into the long holes, so that a travel length of the end parts connected to the belt shape member of the bracket is reduced and a travel length of the belt shape member is also reduced. Thereby, a compression volume of the back pad due to belt shape member is not changed broadly and thus an appearance of the seat back is retained.SELECTED DRAWING: Figure 2
【課題】帯状体によって圧縮されて変形するバックパッドの変形量を抑制し、シートバックの見栄えを担保する。【解決手段】バックパッド32がサイドエアバック20の展開に伴って破断する際に、第1帯状部材70の端部と第2帯状部材72の端部との縫製部80において分裂する力布34を、ブラケット82,100を介して、バックフレーム30に取り付けるための取付構造において、ブラケットの一端部に、帯状部材の端部が連結され、ブラケットの他端部に形成された長孔88,104において、ブラケットがバックフレームにボルト締結される。この際、ブラケットをバックフレームの取付面に対して傾斜させて、長孔にボルトの軸部を挿通することで、ブラケットの帯状部材に連結される端部の移動量は減少し、帯状部材の移動量も減少する。これにより、帯状部材によるバックパッドの圧縮量は大きく変化せず、シートバックの見栄えが担保される。【選択図】図2
