[0002] A car seat is a seat that you sit on when you are in a car. It is usually composed of a seat frame and a filling layer wrapped around the outside of the seat frame. Most of the existing seat frames are one-piece stamping parts, but stamping parts also have some disadvantages. For example, the stamping part structure often has insufficient structural strength due to the thin thickness of the frame body. In order to increase the structural strength of the seat frame, it is usually necessary to weld some reinforcing ribs at the bottom of the seat frame. At this time, a welding fixture is needed.
