The invention provides an ISOFIX (International Standards Organization FIX) mechanism and a safety seat, and relates to the technical field of safety seats, when a rear-end collision accident occurs, an inertia moving part in the ISOFIX mechanism acts due to inertia and drives a locking part to lock an arm shell relative to a sleeve body, and the ISOFIX mechanism swings obliquely upwards relative to an ISOFIX anchor point of a vehicle under the inertia effect, so that the safety seat is prevented from being damaged. According to the safety seat, the gravity of a passenger and the counter-acting force of a vehicle seat on the safety seat jointly consume impact kinetic energy of rear-end collision, the impact kinetic energy which causes swing of the head and the trunk of the passenger in the driving direction is transferred, and injuries caused by rear-end collision between the spine and the head of the passenger can be better prevented. Particularly, the injury caused by acceleration energy impact generated by rapid swing of the neck and the head of the child passenger can be relieved.
本发明提供了一种ISOFIX机构及安全座椅,涉及安全座椅技术领域,在遭受追尾事故时,ISOFIX机构中的惯性活动件由于惯性产生动作,并驱动锁止件将臂壳相对于套体锁止,在惯性作用下ISOFIX机构相对于车辆ISOFIX锚点产生向斜上方的摆动,安全座椅、乘员的重力以及车辆座椅对安全座椅的反作用力共同消耗追尾碰撞的冲击动能,转移了行车方向上导致乘员头部及躯干摆动的冲击动能,可以更好地防止乘员脊椎至头部因追尾事故造成损伤,尤其能够减轻儿童乘员颈部与头部因急速摆动而产生加速度能量冲击所造成的损伤。
