[0029] This invention provides a tool for detecting the unlocking and restoring force of a car seat backrest.

[0030] Please see Figure 1 The seat includes a seat body 1, which includes a seat cushion 11 and a backrest 12. A seat adjuster 13 is installed between the seat cushion 11 and the backrest 12. The seat adjuster 13 is prior art, and its specific working method will not be described in detail here. The seat adjuster 13 can adjust the angle of the seat back according to the needs of different passengers to achieve the best support and comfort, making the seat suitable for different passengers and improving the practicality of the seat.

[0031] Please see Figure 1 , Figure 2 and Figure 3The seat body 1 is provided with a connecting rod 2 on its exterior. Both ends of the connecting rod 2 are fixedly connected with a locking block 7. The top surface of the detection shell 301 is provided with a locking groove 8. The locking block 7 is adapted to the locking groove 8. Through the setting of the connecting rod 2, the two detection shells 301 can be connected, which improves the stability of the detection mechanism 3 in detecting the unlocking and restoring force of the seat back. Through the setting of the locking block 7 and the locking groove 8, the locking block 7 can be inserted into the locking groove 8, which makes it convenient for the staff to install the connecting rod 2 into the two detection shells 301 or remove the connecting rod 2 from the detection shell 301, so as to save the space occupied by the device when it is not in use and facilitate the storage and transportation of the device.

[0032] Please see Figure 1 and Figure 2 The connecting rod 2 is provided with a first restraint strap 4 and a second restraint strap 5. The first restraint strap 4 is fitted on the outside of the seat cushion 11, and the second restraint strap 5 is fitted on the outside of the backrest cushion 12. The first restraint strap 4 and the second restraint strap 5 have good toughness and elasticity, and can be restrained on various car seats of different models. This makes it convenient for testing personnel to test the unlocking and restoring force of the seat backrest, and improves the applicability of the device to the backrest unlocking and restoring force testing of car seats of different sizes.

[0033] Please see Figure 1 , Figure 2 , Figure 3 and Figure 5 Both the first restraint strap 4 and the second restraint strap 5 are equipped with a set of mounting mechanisms 6. The mounting mechanism 6 includes a fixing plate 601, which is fixedly connected to the corresponding telescopic rod 305 or fixing rod 306. The mounting mechanism 6 serves to fix and support the detection mechanism 3, so that the fixing rod 306 can be fixed to the first restraint strap 4 and the telescopic rod 305 can be fixed to the second restraint strap 5. This allows the detection mechanism 3 to maintain a fixed connection with the seat cushion 11 and the backrest cushion 12, which facilitates the subsequent detection of the unlocking and restoring force of the car seat backrest by the detection mechanism 3. The fixing plate 601 is fixedly connected to different telescopic rods 305 and fixing rods 306 according to the change of position.

[0034] Please see Figure 5The outer surface of the fixed plate 601 is fixedly connected to the mounting post 602, and the outer surface of the mounting post 602 is rotatably connected to the fixed sleeve 603. The outer surfaces of the first binding strap 4 and the second binding strap 5 are both fixedly connected to the fixing studs 604. The fixed sleeve 603 and the fixing studs 604 are threaded together. When installing this device, the operator can rotate the fixed sleeve 603 to make the mounting post 602 contact the fixing stud 604. The coefficient of friction between the fixed sleeve 603 and the fixing stud 604 is relatively large. During installation, the fixed sleeve 603 and the fixing stud 604 need to be tightened. When the fixed sleeve 603 is tightened, the fixing stud 604 will abut against the mounting post 602. At this time, the fixed sleeve 603 will be difficult to rotate outside the mounting post 602, so as to avoid the fixed sleeve 603 rotating on its own and affecting the detection accuracy of the device.

[0035] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 Both ends of the connecting rod 2 are equipped with detection mechanisms 3. The detection mechanism 3 includes a detection shell 301. By setting up two detection mechanisms 3, the unlocking and restoring forces on both sides of the car seat back can be detected synchronously to ensure that the backrest can remain synchronized after restoration, preventing the backrest from tilting due to different restoring forces on both sides, and avoiding the backrest tilting from affecting the passenger's experience.

[0036] A support rod 302 is fixedly connected inside the detection housing 301. A rotating disk 303 and a detection disk 304 are rotatably connected to the outer surface of the support rod 302. The rotating disk 303 and the detection disk 304 are rotatably connected. When the car seat back moves, it can drive the telescopic rod 305 to move. At this time, the telescopic rod 305 can extend and retract with the tilt of the backrest, and drive the rotating disk 303 to rotate on the support rod 302. When the backrest returns to its original position, the telescopic rod 305 and the rotating disk 303 will also return to their original positions. The tester can measure whether the unlocking and restoring force of the seat back is qualified by measuring the change in the angle between the rotating disk 303 and the detection disk 304 compared with the angle before the test.

[0037] A telescopic rod 305 is fixedly connected to the outer surface of the rotating disk 303, and a fixed rod 306 is fixedly connected to the outer surface of the detection disk 304. The telescopic rod 305 can extend and retract with the angle change of the backrest and drive the rotating disk 303 to rotate, providing conditions for the device to detect the seat unlocking and restoring force. The fixed rod 306 serves to support the detection mechanism 3. Since the friction between the fixed sleeve 603 and the fixed stud 604 is large, and the resistance of the telescopic rod 305 to extend and retract is small, it can be ensured that the fixed rod 306 is not pulled when the seat backrest moves, thereby ensuring that the position of the detection disk 304 does not change.

[0038] The outer surface of the detection disc 304 is provided with scale lines 307, and the interior of the detection disc 304 is provided with an arc-shaped groove 308. A detection rod 309 is fixedly connected to the outer surface of the rotating disc 303. The detection rod 309 passes through the arc-shaped groove 308 and is slidably connected to the arc-shaped groove 308. One end of the detection rod 309 is equipped with a pointer. When the telescopic rod 305 moves with the backrest, the rotation of the rotating disc 303 can drive the detection rod 309 to rotate inside the arc-shaped groove 308, thereby changing the position of the scale line 307 indicated by the pointer. After the backrest is reset, the telescopic rod 305 and the rotating disc 303 are reset. At this time, the position of the pointer is observed again. If the angle deviation is within an acceptable range, it indicates that the unlocking and restoring force of the car seat backrest is qualified. If it exceeds the range, it proves that the unlocking and restoring force of the car seat backrest is unqualified.

[0039] Working principle: When the operator uses this device to test the unlocking and restoring force of a car seat backrest, firstly, the first restraint strap 4 and the second restraint strap 5 are respectively placed on the seat cushion 11 and the backrest cushion 12. Then, the ends of the telescopic rod 305 and the fixed rod 306 are fixed to the surfaces of the first restraint strap 4 and the second restraint strap 5 respectively through the installation mechanism 6. Then, the locking blocks 7 at both ends of the connecting rod 2 are respectively inserted into the locking slots 8 opened on the top surface of the two detection shells 301. At this time, the installation of the device is completed. The operator then records the position indicated by the pointer at the end of the detection rod 309. Then, the angle of the backrest cushion 12 is adjusted by the seat angle adjuster 13. The movement of the backrest cushion 12 can drive the rotating disk 303 to rotate through the telescopic rod 305. When the backrest cushion 12 returns to its original position, the position of the scale line 307 indicated by the pointer at the end of the detection rod 309 is recorded and compared with the first record. The deviation between the data is observed. If the deviation value is within the acceptable range, it means that the unlocking and restoring force of the car seat backrest is qualified. If it exceeds the range, it proves that the unlocking and restoring force of the car seat backrest is unqualified.
