Claim Text:
1. A method for manufacturing support structures in motor vehicles, in particular parts of a motor vehicle seat, the method comprising: thermoplastically shaping at least one base element of a fabric-reinforced thermoplastic material in a mold to obtain a support structure base, wherein in at least one additional process at least one additional structure comprising reinforcing elements is integrally molded to the support structure base to obtain a seat pan, wherein the seat pan is formed such that tensile stresses occurring in a region of the seat pan during usage are absorbed by the fabric-reinforced thermoplastic material, whereas compressive forces exerted on the seat pan during usage are absorbed by the reinforcing elements, wherein a spring mat with a flat or wave-like cross-section is connected by only a single first edge to the seat pan by being integrally molded to the seat pan or, after thermoplastically forming the seat pan, connected to the seat pan by molding, wherein the spring mat comprises a second edge opposite the first edge at which a connecting structure for connecting the spring mat to a tube of a vehicle seat is formed, wherein the spring mat, after the spring mat has been integrally molded to the seat pan or has been connected to the seat pan by molding, adjoins the seat pan with the first edge and spatially extends from the seat pan such that the spring mat with the second edge opposite the first edge is connectable to the tube of the vehicle seat.
