The invention relates to an automobile seat beam with an unequal thickness and a manufacturing method thereof. The automobile seat beam has a thin-wall structure and comprises an outside section of the beam, an outside transition section, a middle section of the beam, an inside transition section and an inside section of the beam in turn, wherein mounting holes for connecting a seat are formed in the outside section of the beam and the inside section of the beam; the outside section of the beam has an equal-thickness structure; the thickness of the outside section of the beam is continuously changed into the thickness of the middle section of the beam through the outside transition section; the inside section of the beam has the equal-thickness structure; the thickness of the inside section of the beam is continuously changed into the thickness of the middle section of the beam through the inside transition section; the thicknesses of the outside transition section and the inside transition section are gradually reduced from the thick areas at the two ends to thin areas towards the middle section of beam; the thickness of the middle section of beam is the minimum thickness of the whole seat beam. According to the invention, through the design for the parts in different thicknesses, the demands on impact safety and mounting strength of the automobile seat beam are met, and meanwhile, light weight of the parts is realized.
