  • Patent number: 7219958
    Abstract: This child car seat includes a child car seat body, a back portion rotatably held in inclination by the child car seat body, a seat portion rotatably connected to a lower part of the back portion and a shock absorbing mechanism arranged between the child car seat body and either one or both of the back portion and the seat portion. The seat portion and the back portion hold a newborn. When an impact force directing from a front face side of the back portion toward its back face side is applied on the newborn, the back portion rotates in its rising direction and the shock absorbing mechanism operates to reduce the impact force applied on the newborn. Consequently, the newborn can be held on the child car seat in a state close to a condition where the newborn lies on its back. Since the back portion stands up at the time of impact, the newborn is capable of receiving the impact through the whole area of a newborn's back.
