  • Patent number: 7246813
    Abstract: A casing (32) included in a baby carriage folding mechanism is mounted on a substantially middle part of the handle of a folding baby carriage. Hinged joints (33) each having a stationary member (34) and a movable member (35) are connected to the opposite ends of the casing (32), and pipes (18) forming the handle are connected to the hinged joints (33), respectively. The pipes (18) are connected to the movable members (35) of the joints (33). Actuating members (38a and 38b) capable of being operated by an operating mechanism included in the casing (32) are connected to the movable members (35) of the hinged joints (33). The actuating members (38a and 38b) turn the movable members (35) relative to the corresponding stationary members (34) for folding and developing the folding baby carriage.

  • 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.
