【0014】 本発明によれば、土手部の裏側の面に凹部が形成されているので、土手部のうち凹部が形成されている部位が後退して撓むスペースが確保されている。他車両が自車両の後方から自車両の後部に衝突した時には、乗員の上体の側部が土手部に受け止められても、土手部のうち凹部が形成されている部位が後退して撓む。よって、乗員の上体が後方に沈み込むことが土手部によって低減されることを抑制することができる。 また、乗員がバックレストに凭れかかった時には、土手部のうち凹部が形成された部位が受圧部材の延出部によって受け止められる。土手部の裏面に凹部が形成されることによって、土手部自体のホールド性が低下しても、延出部によってホールド性を補うことができる。
