• the seat adapter 18a is connected to the detent portion 22a of the detent fitting mechanism 22. Since the detent fitting mechanism 22 is substantially known, further detailed description thereof will be omitted.
• Fig. 1 1 shows schematically in another perspective view of the detail of FIG. 10. It can be clearly seen how the seat portion 18 and the seat adapter 18a are arranged on the outside of the backrest longitudinal strut 12.

• FIG. 13 shows schematically in a perspective view a comparison of an embodiment according to the invention with the prior art in a rear view.
• D the gained lateral distance is plotted against the prior art. Due to the fact that the backrest adapter 16 is arranged on an inner side, the outer part of the adjusting device no longer builds so large.

• SdT the position of the seat adapter according to the prior art. It can be clearly seen that the inventive arrangement of the seat adapter saves a significant distance D in the axial direction. In addition to the axial distance D, a more favorable force curve is also realized. With KV (SdT) a force curve according to the prior art is shown.
• the force curve according to the invention runs substantially closer along the backrest longitudinal strut 12, that is, more centrally between the seat adapter 18a and the backrest adapter 16a. In the prior art, the force curve is significantly further out of the center, since both seat adapter 18a and backrest adapter 16 laterally outside the
