AI Technical Summary
Under vibration, the seat belts of existing crash test dummies are prone to loosening, causing displacement of the dummy on the attitude adjustment equipment and affecting the accuracy of the test.
The anti-detachment mechanism uses bolts and rubber rods to lock the block securely through threaded connections and the snap-fit of the rubber rod. Combined with a limit rod and anti-slip pad, it enhances the stability of the dummy on the seat, and uses a servo motor for posture adjustment.
This effectively prevents the locking blocks from loosening within the locking frame, ensuring the restraint straps are stably secured to the dummy, thus improving the accuracy of crash tests and the stability of the dummy in the seat.
