  • Such a structure of the mechanism makes it possible to vary the correlated movement of the seat and backrest to each other with particularly simple structural means.
  • the synchronous course of the seat and backrest can be modified, for example, by a simple change of the course of the second guide element.
  • only the attitude angle of a guide slot in the seat carrier must be changed in order to obtain a different motion characteristic.
  • the base carrier is preferably connected by the front pair of guide elements with a front region of the seat carrier and by the rear pair of guide elements, preferably with a rear region of the seat carrier. This can also allow a separate movement curve of the front portion of the seat support and the rear portion of the seat support.

Without the coupling element would be the desired Relative movement of seat support and backrest support not possible because both components, due to their respective predetermined trajectories relative to the base support, would lock against each other. On the other hand, can be accomplished by the coupling element, a special, advantageously synchronous movement of backrest support and seat support, which, as explained in more detail below, a desired variable transmission ratio result.
