    • A seat according to this invention comprises a seat part and a backrest attached to a rear side of the seat part. The seat part comprises a cushion attached to a pair of side supporting frame members connected with each other. The backrest comprises a cushion attached to an inverse U shaped back frame. Each end of the inverse U shaped back frame is connected to each rear end of the side supporting frame members of the seat part. The inverse U shaped back frame comprises side supporting parts that are positioned in parallel and a top supporting part that connects top ends of the side supporting parts. Lower ends of side supporting parts are connected to rear ends of the side supporting frame members of the seat part via lower attaching parts, respectively. Each lower attaching part has an ear part that projects frontward. Supporting members connect between the side supporting parts and the ear parts of the lower attaching parts, respectively. According to this invention, a rearward tilting of its backrest can be restrained and absorb impact energy when a rear impact acts on the seat.
    • 根据本发明的座椅包括座椅部件和靠在座椅部件后侧的靠背。 座椅部件包括一个靠在一对彼此连接的侧面支撑框架构件上的缓冲垫。 靠背包括附接到逆U形后框架的垫子。 逆U形后框架的每个端部连接到座椅部件的侧支撑框架构件的每个后端。 逆U形后框架包括平行定位的侧支撑部分和连接侧支撑部分的顶端的顶部支撑部分。 侧支撑部分的下端分别经由下安装部分连接到座部件的侧支撑框架构件的后端。 每个下连接部分具有向前突出的耳部。 支撑构件分别连接在侧支撑部分和下附接部分的耳部之间。 根据本发明,可以抑制其靠背的向后倾斜,并且当后部冲击作用在座椅上时吸收冲击能量。
