The invention discloses a waist support structure, a seat and an automobile, and the waist support structure comprises a frame which can be connected with the seat of the automobile, and a first support plate of which one end is hinged to one end of the frame; one end of the second supporting plate is connected with the other end of the first supporting plate through a bidirectional hinge, the other end of the second supporting plate is slidably connected to the other end of the frame through a cross rod, the two ends of the adjusting structure are connected with one end of the first supporting plate and the other end of the second supporting plate respectively, and the linear distance between the two ends of the adjusting structure is adjustable. When the bidirectional hinge of the waist support structure is subjected to backward acting force of a passenger backrest, the first supporting plate and the second supporting plate can move backwards, the supporting strength of the seat backrest to the passenger backrest is reduced, the back moves backwards along with the head of the cervical vertebra, then the difference value between the acceleration of the backrest and the acceleration of the head is reduced, and the cervical vertebra of a passenger is protected.

    本发明公开了一种腰托结构、座椅和汽车,包括:框架,框架能够与汽车的座椅连接,第一托板,第一托板的一端铰接在框架的一端;第二托板,第二托板的一端通过双向铰链与第一托板的另一端连接,第二托板的另一端通过横杆滑动连接在框架的另一端,调节结构,调节结构的两端分别与第一托板的一端和第二托板的另一端连接,调节结构的两端之间的直线距离可调,该腰托结构的双向铰链在受到乘员靠背向后作用力时,可以使第一托板和第二托板向后运动,减小座椅靠背对乘员靠背的支撑强度,使后背随颈椎头部一同向后运动,进而缩小靠背加速度和头部加速度的差值,保护乘员的颈椎。
