PROBLEM TO BE SOLVED: To overcome a conventional problem that, if a lid body of an airbag case supports an inflated and deployed seated passenger protection apparatus (airbag) from behind during a lateral collision, large bending moment acts on the lid body and the airbag is unable to sufficiently exhibit the protection function.SOLUTION: An airbag case 20 comprises therein an airbag 22, and has a lid body 20b having a seated-passenger-side sidewall which is rotatable upward about an upper end thereof serving as a rotation center. A support member (rib) 30 is provided on a seated-passenger-side surface 20b1 of the lid body 20b. When the expanded airbag 22 is inflated and deployed from an opening formed in a seated-passenger-side lateral section of an armrest 16, the lid body 20b is pressed by the airbag and rotates upward. The support member 30 on the seated-passenger-side surface of the lid body rises, is located on the airbag case, and supports the lid from behind. The lid body can resist bending moment acting thereon during a lateral collision and the airbag 22 can sufficiently exhibit a protection function thereof.SELECTED DRAWING: Figure 3
【課題】側突時に、エアバッグケースの蓋体が膨出、展開された着座者保護装置(エアバッグ)を背後から支えると、大きな曲げモーメントが蓋体に作用し、エアバッグがその保護機能を十分発揮できない。【解決手段】エアバッグケース20は、その内部にエアバッグ22を備えるとともに、着座者側の側壁がその上端を回動中心として上方に回動可能な蓋体20bを有している。蓋体20bの着座者側の面20b1には支持部材(リブ)30が設けられている。膨張したエアバッグ22がアームレスト16の着座者側の側方に形成された開口から膨出、展開すると、エアバッグに押されて蓋体20bが上方に回動する。蓋体の着座者側の面の支持部材30が起立し、エアバッグケース上に位置して蓋体を背後から支える。蓋体20bが側突時に作用する曲げモーメントに抗し、エアバッグ22はその保護機能を十分に発揮できる。【選択図】図3
