1. A method of manufacturing at least one of a vehicle seat structure, a vehicle seat and a vehicle seat bench, comprising:
forming at least one back shell extending in a direction transverse to a direction of travel and having a front side relative to the direction of travel and a back side relative to the direction of travel, a frame structure shell, reinforcement ribs arranged on the front side of the back shell, absorption ribs arranged on the back side of the back shell, and structural insertion components arranged on the back shell and/or the frame structure, wherein said forming includes connecting at least the back shell and the frame structure to each other in a plastic to plastic manner by melting surfaces of the back shell and the frame structure and subsequently joining the back shell and the frame structure at those melted surfaces to form a one-piece integrated structural component, wherein the back shell comprises an inner portion and an outer portion, wherein the back shell and the frame structure are molded such that the frame structure surrounds and encloses the inner portion of the back shell in the direction transverse to the direction of travel and separates the inner portion of the back shell from the outer portion of the back shell, wherein the back shell and/or the frame structure include thermoplastic, and said forming includes encasing at least areas of the structural insertion components in the thermoplastic of the back shell and/or the frame structure, and wherein the reinforcement ribs and the absorption ribs each include a plurality of horizontal ribs and vertical ribs, wherein the reinforcement ribs and the absorption ribs surround the structural insertion components on the front side and back side, respectively, of the back shell in the direction transverse to the direction of travel, wherein the reinforcement ribs are arranged on the inner portion and the outer portion of the front side of the back shell, wherein the absorption ribs are arranged on the inner portion and the outer portion of the back side of the back shell.
