With reference to shown in Fig. 6~8, artificially start push rod, mounting bracket is released optional position, such as Fig. 6 to Fig. 7 work by push rod
Shown in cardon, triggering pulling force sensor 110 sends the first monitoring signal；Safety seat control unit (ECU) receive this first
Monitoring signal, automatic start recliner motor, driving recliner 23 is rotated, and the backrest 22 of child safety seat is adjusted backward,
When the backrest 22 of child safety seat is close to motor vehicle seat back 20, be arranged on pressure sensor 120 on backrest 22 by
The effect of motor vehicle seat back 20, sends the second monitoring signal；The pressure sensor 120 that ECU is set by detecting on backrest 22
The second monitoring signal sent, it can be determined that correct position is arrived in the regulation of child safety seat chair back, and backward recliner motor is again
An operational order for stopping start being sent, stops the rotation of recliner, as shown in figure 8, completing isofix devices to backrest 22
Linkage regulation.
In conjunction with shown in Fig. 9~11, artificial regulation starts recliner motor, such as making shown in cardon for Fig. 9 to Figure 10, triggering
Pressure sensor 120 sends the second monitoring signal；Safety seat control unit (ECU) receives second monitoring signal, automatically
Start isofix motors, the push rod of driving isofix devices is released, with the extension elongation for the push rod for adjusting isofix devices；At the very moment
When the backrest 22 of virgin safety seat is close to motor vehicle seat back 20, the drawing between the detection push rod of pulling force sensor 110 and mounting bracket
Power, and send out the first monitoring signal；What ECU received first monitoring signal and measured by judging pulling force sensor 110
Pulling force understands whether push rod reaches correct extension elongation, and the operation that a stopping start occurring again for backward isofix motors refers to
Order, stops push rod start, as shown in figure 11, completes linkage of the backrest 22 to isofix devices and adjusts.
In the present embodiment, it can also be utilized using isofix motors are electrically connected into safety seat control unit (ECU)
The current signal sent during isofix electric motor startings directly triggers ECU, ECU automatic start recliner motors, subsequently to be adjusted
Angle device regulation.Similarly, recliner motor can be utilized using recliner motor is electrically connected into safety seat control unit (ECU)
The current signal sent during startup directly triggers ECU, and ECU automatic start isofix motors are adjusted with carrying out follow-up isofix devices
Section.Pressure sensor in the present embodiment may also be arranged on automotive seat, as long as pressure sensor is arranged on into children's safety
The contact surface of seat and automotive seat.
Embodiment 3：
