In a manufacturing method (HV) for producing finished leather (FL) for covering components with leather, wherein the following process steps for treating a leather hide (LH) are performed on a raw hide (RH) as an initial product for producing the finished leather (FL) as an end product of the method: mechanical process steps in which the leather hide (LH) is treated using mechanical tools, and chemical process steps in which the leather hide is treated with chemicals, wherein both mechanical and chemical modes of action are combined in individual process steps, it is envisaged that, in a process step of retanning, synthetic and/or vegetable tanning materials, fattening agents, microencapsulated auxiliary agents based on ammonium, phosphate, phosphorus and the ester compounds thereof and natural additives based on rubber and milk products are used, and in a process step of reducing the thickness of the leather hide, the leather thickness of the leather hide (LH) is reduced by splitting and/or scraping without reducing the physical authenticity, and in a process step of flame retardant application, an application material (AM) consisting of acrylic, polyurethane, vinyl acetate dispersions and having a flame retardant based on cyclic di- and triphosphates and organic ammonium with sulphur and phosphorus compounds is applied on the flesh side (FS) of the leather hide (LH).
