Description

Technical Field

[0002] Before the car seats are shipped out of the factory for installation, a batch of seats will be selected and a series of strength tests will be carried out. Only after the test parameters are qualified can they be put on the market. In the car seat strength test, the car seat is placed in the designated position, and the corresponding strength test is carried out on the car seat through the corresponding "strength tester". Because in the existing seat strength test, the car seat is placed on the test bench, and the car seat itself is kept stable during the strength test through its own structure. In this way, if the car seat itself is stable, during the strength test, if the external force applied exceeds the "balance force" of the car seat itself, the car seat is likely to move or overturn, affecting the strength test. In this regard, in order to facilitate the stability of the car seat during the strength test, a device for "stabilizing" the car seat during the strength test of the car seat is designed and improved.
