2. Description of the Prior Art
Child safety seats are installed on vehicle seats to provide ride and enhanced protection for children, which can effectively improve children's riding safety. A safety belt system of the child safety seat usually includes a shoulder belt and a crotch belt located between a user's legs. The conventional crotch belt is connected to a buckle at one end and connected to a metal bracket at the other end so as to connect to a seat body of the child safety seat. The conventional crotch belt has many defects. For example, when the crotch belt is not in use, the crotch belt connected to the buckle often falls naturally in a center of a seat cushion due to the weight of the buckle. As a result, when a child is to be placed in the child safety seat, the crotch belt and buckle will hinder the child from riding, so the crotch belt must be removed first. When a caregiver holds a baby with both hands, the action of removing the crotch belt in advance often causes trouble for the caregiver. In addition, the crotch belt is connected to the seat body via the metal bracket, and the connecting structure is complicated and difficult to be disassembled, which is inconvenient for cleaning and replacement of the crotch belt. Therefore, there is a need for developing a buckle fastening device with simple structure and easy disassembly, which is convenient to use by caregivers.

That is, the protecting pad 210 can be positioned at the working position by overcoming a recovering force of the positioning structure 220. A buckling device 300 is disposed on the belt body 200. After releasing the buckling device 300, the positioning structure 200 can drive the protecting pad 210 connected with the buckling device 300 away from the working position in an unstressed condition, so as to enhance riding comfort.
It should be noted that the belt body 200 can be, but is not limited to, a crotch belt or a shoulder belt. The cushion body 110 can be a cushion pad installed on the seat portion 101, but it is not limited thereto. Specifically, taking the crotch belt as an example but not limited to it, as the belt body 200 is a crotch belt, the buckling device 300 connected to the belt body 200 is used to connect with the shoulder belt on the child safety seat 100 to form a safety belt system of the child safety seat 100 so as to provide safe protection for children. The buckling device 300 can be, but is not limited to, a buckle or strap connection form. Furthermore, the positioning structure 220 can be resilient, that is, the positioning structure 220 can be made of resilient material. For example, the positioning structure 220 can be an elastic sheet, a spring, etc. Specifically, the positioning structure 220 can be, but is not limited to, a PE plate. Furthermore, the one end of the positioning structure 220 can be fixedly connected or detachably connected to the cushion body 110, and the another end of the positioning structure 220 is fixedly connected with or detachably connected with the protecting pad 210. For example, the one end of the positioning structure 220 can be fixedly connected to the cushion body 110 in one of sewing connection, adhesive connection and buckling connection, and the another end of the positioning structure 220 can be fixedly connected with the protecting pad 210 in one of sewing connection, adhesive connection and buckling connection.
Please refer to FIG. 2 to FIG. 4. FIG. 3 is a diagram of the partial belt body 200 installed on an upper surface of the cushion body 110 according to the first embodiment of the present application. FIG. 4 is a diagram of the partial belt body 200 installed on a lower surface of the cushion body 110 according to the first embodiment of the present application. In this embodiment, the one end of the positioning structure 220 is fixedly connected to the cushion body 110, and the another end of the positioning structure 220 is detachably connected with the protecting pad 210. The fixed connection can be, but is not limited to, one of sewing connection, adhesive connection and buckling connection. In this embodiment, the one end of the positioning structure 220 and the cushion body 110 can be fixedly connected by sewing, so that the positioning structure 220 and the cushion body 110 are connected stably, thereby not being easy to fall off.
