Description
また、請求項1記載の車両用シートによれば、可動支持部が固定支持部にシート前後方向に傾動可能に支持されている。これにより、車両の衝突時におけるシートバックのシート上方側の部分の変位量をシートバックのシート下方側の部分及びシートクッションの変位量よりも大きくすることできる。これにより、車両用シートに着座した乗員の胸部や頭部への衝撃を効果的に低減することができる。
請求項4記載の車両用シートは、請求項3記載の車両用シートにおいて、前記エネルギ吸収部材のシート前後方向への厚み寸法が、シート左右方向の厚み寸法よりも厚い寸法に設定されている。
次に、本実施形態の作用並びに効果について説明する。
一例として、図4に示されたシート支持装置36では、可動支持部26の軸部26Bの右側の端から通過孔32Aの縁までの左右方向への厚み寸法T3(b)が、可動支持部26の軸部26Bの左側の端から通過孔32Aの縁までの左右方向への厚み寸法T3(d)よりも薄い寸法に設定されている。また、可動支持部26の軸部26Bの前側の端から通過孔32Aの縁までの前後方向への厚み寸法T3(c)が、可動支持部26の軸部26Bの後側の端から通過孔32Aの縁までの前後方向への厚み寸法T3(a)よりも厚い寸法に設定されている。このように、エネルギ吸収部材28の各部の厚みを互いに異なる寸法に設定することで、車両用シート10が向けられた方向及び車両の衝突方向に応じて、シートクッション12及びシートバック14を所望の変位量だけ変位させることができる。
