The invention provides a head and neck protection device for vehicle rear-end collision. The head and neck protection device comprises a headrest seat, a first buffer assembly and a limiting mechanism. When a vehicle is subjected to rear-end collision, the collided vehicle accelerates forwards to enable the head of a person in the vehicle to collide with a first soft cushion, the first soft cushion drives a guide seat to move after being collided, the guide seat moves to extrude multiple sets of buffers, at the moment, the first soft cushion and the multiple sets of buffers are matched to buffer collision of the head, and the buffering effect of the device is improved; meanwhile, the guide seat moves to drive the fixing assembly to relieve fixing of the limiting rod, the driving piece drives the limiting rod to rotate to a second state at the moment, so that the arc-shaped part of the limiting rod is opposite to the first soft cushion, and when the head moves forwards due to impact reaction force, the limiting rod can abut against the head, so that the head is limited to move forwards by a large margin; the neck strain is avoided, and the protection effect of the device is improved.
本发明提供一种车辆追尾碰撞头颈防护装置,包括头枕座、第一缓冲组件和限位机构。当车辆发生追尾碰撞后,被撞车辆向前加速运动使车内人员头部撞击在第一软垫上,第一软垫受到撞击后驱动导向座移动,导向座移动挤压多组缓冲器,此时,第一软垫和多组缓冲器配合对头部的撞击进行缓冲,提高装置的缓冲效果,降低头部的撞击伤,同时导向座移动驱动固定组件解除限位杆的固定,此时驱动件驱动限位杆转动至第二状态,从而使限位杆弧形部与第一软垫相对,当头部因撞击反作用力向前运动时,限位杆可与头部抵触,从而限制头部大幅度向前移动,避免颈部拉伤,提高装置的防护效果。
