1. A vehicle seat, comprising: a seat part, a backrest and a bearing device for supporting a backrest extension part relative to a lower backrest part of the backrest of the vehicle seat,whereinthe bearing device comprises a plurality of plain bearing bush units for supporting elongated transverse elements of the backrest extension part along sliding axes arranged perpendicular to the backrest, and wherein the plain bearing bush units are assembled from identically designed asymmetrical bearing bush parts and the respective asymmetrical bearing bush part has a plain bearing structure that is partly open radially relative to the sliding axis. 2. The vehicle seat according to claim 1, whereinthe respective asymmetrical bearing bush part comprises a radial assembly opening for radially mounting the asymmetrical bearing bush part onto one of the elongated transverse elements. 3. The vehicle seat according to claim 1, whereinthe respective asymmetrical bearing bush part forms a portion of a plain bearing structure of the plain bearing bush unit, which is partly open radially relative to the sliding axis. 4. The vehicle seat according to claim 1, whereinthe respective asymmetrical bearing bush part forms a portion of a plain bearing structure of the plain bearing bush unit, wherein the plain bearing structure on its circumference on the one hand has a plain bearing structure gap and on the other hand a gap filling element for closing a plain bearing structure gap of a further asymmetrical bearing bush part of a common plain bearing bush unit corresponding to the asymmetrical bearing bush part. 5. The vehicle seat according to claim 4, whereinthe plain bearing structure gap and the gap lining element are spaced apart from one another by the diameter of a plain bearing opening. 6. The vehicle seat according to claim 4, wherein the assembly web element and the gap filling element are arranged on the same bearing bush part side. 7. The vehicle seat according to claim 1, whereina plain bearing structure formed in the asymmetrical plain bearing bush passes obliquely through the plain bearing bush unit. 8. The vehicle seat according to claim 1, whereinthe sliding axis passes obliquely through the plain bearing bush unit. 9. The vehicle seat according to claim 1, whereinthe sliding axis of the plain bearing bush unit runs obliquely to the total depth extension of the plain bearing bush unit. 10. The vehicle seat according to claim 1, whereinthe plain bearing structure comprises an inner plain bearing toothing. 11. The vehicle seat according to claim 1, whereinthe plain bearing bush unit is assembled from two identically designed asymmetrical bearing bush parts, wherein the bearing bush parts are aligned with one another on their identically configured side. 12. The vehicle seat according to claim 1, whereinthe asymmetrical bearing bush part comprises a plate-like base body element having a longitudinal extension and a width extension of which are perpendicular to the sliding axis of the plain bearing bush unit. 13. The vehicle seat according to claim 1, whereinthe asymmetrical bearing bush part comprises a plate-like base element having a depth extension is aligned with the sliding axis of the plain bearing bush unit. 14. The vehicle seat according to claim 1, whereinat least one of the plain bearing bush units is arranged radially displaceably relative to the sliding axis in a support seat of the bearing device. 15. The vehicle seat according to claim 1, whereina third plain bearing bush unit arranged radially next to a common sliding axis formed by the two plain bearing bush units is arranged rotated by 90° in an additional support seat of the bearing device. 16. The vehicle seat according to claim 1, whereintwo plain bearing bush units forming a common sliding axis are arranged in a mirror inverted manner in support seats of the bearing device. 17. The vehicle seat according to claim 1, whereina third plain bearing bush unit arranged radially next to the common axial sliding axis formed by the two plain bearing bush units is arranged between the two plain bearing bush units and forms a further axial sliding axis. 18. The vehicle seat according to claim 1, whereinthe asymmetrical bearing bush part on an assembly side corresponding with a further asymmetrical bearing bush part comprises at least one assembly web element, which can be inserted into an assembly bore of the other asymmetrical bearing bush part to form the plain bearing bush unit. 19. A utility vehicle comprising at least one vehicle seat, wherein the at least one vehicle seat is configured according to claim 1.
