Abstract
According to a method for producing support structures in motor vehicles, especially parts of a motor vehicle seat, at least one base element (BE) consisting of a thermoplastic material with a fabric back stay, especially a glass fiber reinforced thermoplastic (GMT) is inserted into tool (8) to form a support structure base (TB), is thermoplastically deformed and is subjected, at the same time or subsequently, to at least one additional process for reinforcing the support structure base (TB), integrally forming at least one additional structure (ZS), and integration of functional parts or integration of interfaces for additional components into the support structure (TB).

25. A method for manufacturing support structures in motor vehicles, in particular parts of a motor vehicle seat,
wherein at least one base element of a fabric-reinforced thermoplastic material, in particular a glass fiber mat thermoplastic, is inserted into a mold for forming a support structure base and is thermoplastically formed in the mold, and in at least one additional process the support structure base is reinforced and/or at least one additional structure is integrally molded and/or functional parts and/or interfaces for additional components are integrated into the support structure base, wherein the support structure consists of a seat pan of a motor vehicle whose structural strength in the region of tensile stresses occurring in the seat pan during usage is absorbed by the fabric-reinforced thermoplastic material of the base element, whereas in the region of compressive forces exerted on the seat pan during usage stiffening or reinforcing elements, in particular stiffening ribs, of reinforced plastic material are injection-molded to increase the rigidity, wherein a spring mat with flat or wave-like cross-section is integrally molded to the seat pan or, after thermoplastically forming the seat pan, an additional structure formed as spring mat with flat or wave-like cross-section is molded to the seat pan.
