The invention discloses an anti-collision seat backrest small table board, and relates to the technical field of seat backrest table boards, the anti-collision seat backrest small table board comprises a mounting rack, an upper table board, a lower table board, two upper movable support rods, two lower movable support rods, two connecting pieces, a second connecting rod and reset springs, the two ends of the second connecting rod are connected with safety hooks through the reset springs; according to the table board with the design, when a passenger on a rear seat collides with the table board which is just opened due to inertia, transverse collision force is generated on the table board, the transverse force can drive the collision block to collide with the safety hook, and therefore the safety hook is not prone to falling off, and the safety hook is not prone to falling off. When the panel is collided, the convex hook of the lower movable supporting rod is separated from the concave hook of the safety hook, two fixing points of the connecting piece and the lower movable supporting rod are changed into one fixing point, the connecting piece can rotate relative to the lower movable supporting rod, the panel is automatically stored in the direction of the mounting frame, and therefore the body safety of a collided person is guaranteed.
本发明公开了一种防碰撞座椅靠背小桌板,涉及座椅靠背桌板技术领域,包括安装架、上桌板、下桌板、两个上活动支撑杆、两个下活动支撑杆、两个连接件、第二连接杆和复位弹簧,第二连接杆的两端通过复位弹簧连接保险钩,下桌板的下表面两侧对称开设有滑槽,上桌板的一端底部安装有与滑槽滑动连接的滑板和撞击块,本设计的桌板在后座乘客由于惯性撞向正打开着的桌板时,对桌板产生横向碰撞力,横向力会带动撞击块撞击到保险钩上,使下活动支撑杆的凸钩脱离保险钩的凹钩,使连接件与下活动支撑杆由两个固定点变成一个固定点,而连接件则会与下活动支撑杆发生旋转,面板自动向安装架方向收纳,从而保证被碰撞人的身体安全。
