In this embodiment, the first detecting member 111 is preferably a mechanical switch, which includes but is not limited to a button switch and a spring switch, when the button switch shown in fig. 4-5 is selected, the first detecting member 111 has a button 1111, the first detecting member 111 is mounted to the backrest of the base 210 or the seat body 220 and protrudes the button 1111 to the moving path of the top strap 230, when the spring switch shown in fig. 7-8 is selected, the first detecting member 111 has a spring 1112, the first detecting member 111 is mounted to the backrest of the base 210 or the seat body 220 and protrudes the spring 1112 to the moving path of the top strap 230. Therefore, when the top strap 230 is pulled in the direction of arrow F1 in fig. 4-5 and 7-8, the top strap 230 applies a force to the button 1111 or the resilient tab 1113 of the first detecting member 111 to close the button 1111 or the resilient tab 1113, so that the detecting circuit of the first detecting device 110 is turned on to generate the first detecting signal, and when the top strap 230 is loosened, the first detecting member 111 (mechanical switch) loses the force and is automatically turned off, and the first detecting device 110 cannot generate the first detecting signal.
