According to the seat framework capable of being folded to sink, the seat framework capable of being folded to sink is adopted, a lead screw motor drives the seat cushion to sink and rise, the seat cushion is matched with a sliding groove to sink to a lower position, meanwhile, a sitting and leaning separated structure is adopted, and the seat framework capable of being folded to sink has a lower height and a flatter surface after being folded; the rear space can be expanded in cooperation with forward movement of a longer sliding rail, and meanwhile the purpose of providing pedals for passengers in the rear row is achieved; the whole stroke of the cushion sinking mechanism is downward, and the problem that the service life of a surface cover is shortened due to excessive extrusion caused by small-section lifting before sinking of an old toothed plate structure is solved; and the cushion sinking mechanism adopts a sitting and leaning separated structure, so that the forward folding angle of the backrest is larger, meanwhile, excessive influence on the shape of the cushion is avoided, and the shape is more attractive.

    本发明提供了一种可以折叠下沉的座椅骨架,采用的可以折叠下沉的座椅骨架,坐垫下沉采用的是丝杠电机驱动坐垫下沉与上升,配合滑槽下沉到更低的位置,同时采用坐、靠分离的结构,折叠后拥有更低的高度,更平的表面,配合更长的滑轨向前运动,后部空间也可得到拓展,同时达到为后排乘员提供脚踏的目的;坐垫下沉机构全行程向下,区别老式齿板结构下沉前会有一小段抬升,过度挤压导致面套寿命降低;坐垫下沉机构采用坐、靠分离结构,靠背向前翻折角度更大,同时不会对坐垫造型产生过多影响,造型更为美观。
