Abstract: A child car seat comprises a child car seat body, a back portion, and a seat portion connected to the child car seat body. The back portion is rotatably connected to the child car seat body, and the bottom end of the back portion is pulled toward the seat portion side by a spring member at a normal time. At a time of impact, an impact force larger than a force of the spring member rotates the back portion so that the back portion moves away from the seat portion.

Abstract: A child seat comprises a main body, a seat portion which is supported by the main body so as to be movable in a longitudinal direction, a back portion which is connected to the main body so as to be pivotable around an axis in a lateral direction and be movable within a predetermined range in a direction orthogonal to the axis, and which is pivotally connected to a rear end part of the seat portion on a lower end side thereof, and a restraint belt which is drawn out to a rear side of the back portion from a restraint position on an upper surface side of the seat portion through the back portion, and which is extended to a restraint position on a front end part of the seat portion via a lower surface side of the seat portion.

Abstract: An improved child safety set is disclosed, which in a thin and simple structure using an unconventional material is highly capable of shock absorption by dispersing a body pressure omnidirectionally to protect the head and the stomach of an infant seated in the safety seat in a traveling vehicle. At least in a head corresponding portion (1e) of a child safety-seat main body (1) there is disposed a mass of a cushioning material that is capable of absorbing an impact by dispersing a pressure thereof. Such a mass of cushioning material is preferably a mass of gel material (8) or a liquid sealed flexible bag (30).
