A light seat structure of a motor train unit comprises a bottom frame framework, a rotating frame framework rotationally installed on the bottom frame framework and a backrest framework with the bottom end hinged to the rotating frame framework. The bottom frame framework, the rotating frame framework and the backrest framework are all hollow carbon fiber components; the thickness of the backrest framework is gradually increased from top to bottom, so that the front side surface of the backrest framework is an arc-shaped surface. According to the embodiment of the invention, the framework of each part is made of light carbon fibers, the interior is hollow, the overall weight of the seat is reduced, the seat has high structural strength, the front side surface of the backrest is conveniently processed into a curved plate structure which fits a comfortable curved surface of a human body, the comfort of the seat is improved, and the service life of the seat is prolonged. The problems that an existing motor train unit seat structure is large in weight and poor in comfort are solved.
一种动车组轻质座椅结构,包括底架骨架、旋转安装在底架骨架上的转架骨架以及底端铰接在转架骨架上的靠背骨架;底架骨架、转架骨架和靠背骨架均为中空的碳纤维构件;靠背骨架的厚度自上而下逐渐增加,用以使靠背骨架的前侧面呈弧形面。本发明实施例中各部分骨架均由轻质的碳纤维制成,并且内部中空,降低了座椅整体的重量,并且具有较强的结构强度,靠背的前侧面便于加工成贴合人体舒适性曲面的曲面板结构,提升了座椅的舒适度,解决了当前动车组座椅结构重量较大、舒适性不佳的问题。
