Abstract: A manufacturing method for a child carrying device includes the following steps: providing a mold and disposing a main body of the child carrying device into the mold, and injecting a foam material into a cavity of the mold and foaming the foam material so as to form a flexible layer integrated with the main body. The manufacturing method disposes the main body into the mold and directly forms a flexible layer on the main body, so that the flexible layer ensures safety and comfort of the child carrying device while saves the necessity to dispose a seat pad or a cushion and fixing structures on the main body, and thereby reduces the cost and the work-hour of assembly, and the overall weight of the child carrying device can be reduced by omitting the fixing structures.

Abstract: A manufacturing method for a car safety seat includes the following steps: providing a mold and disposing a main body of the car safety seat into the mold, and injecting a foam material into a cavity of the mold and foaming the foam material so as to form a flexible layer integrated with the main body. A pressure in the cavity is between 1.5 bar and 5.0 bar. The manufacturing method disposes the main body into the mold and directly forms a flexible layer on the main body, so that the flexible layer ensures safety and comfort of the car safety seat while saves the necessity to dispose a seat pad or a cushion and fixing structures on the main body, and thereby reduces the cost and the work-hour of assembly, and the overall weight of the car safety seat can be reduced by omitting the fixing structures.

Abstract: A car safety seat is disclosed in the invention, including a main body and a flexible layer. Multiple air vents are formed on the main body and penetrate through the main body along a front-to-rear direction. The flexible layer is formed on a surface of the main body and in the air vents. The multiple air vents enable vapor to pass through the main body without being blocked by the main body during a foaming process, which thereby allows foaming particles to fully contact with the vapor to ensure an enhanced foaming effect. Also, the flexible layer is not only formed on the surface of the main body but also formed in the air vents to fill the air vents, and thereby the flexible layer is more tightly combined with the main body to reduce a risk of detachment from the main body.
