[0002] The automobile seat frame is used to support the weight of the entire seat and the human body. To ensure the seat strength and the appearance of the seat, it is required to have sufficient ability to resist deformation. According to the actual use situation, the seat frame will be subjected to certain acting forces, which will cause deformation of the seat frame. If the rigidity of the seat frame does not meet the requirements, under the action of the force, the deformation will be large, which will have a negative impact on the in-vehicle noise, the comfort of the seat, the vibration performance, and the safety. Under the action of the load, even if the seat frame has sufficient strength, if the deformation is too large or damage occurs, it still cannot work properly. The rigidity requirement means that the component should have sufficient ability to resist deformation. Therefore, it is extremely important to test the rigidity of the seat frame.
