Definitions

  • a strut extends from the rear wall to the front part of the seat surface on the respective side of the seat surface and connects the rear wall to the seat surface. It was initially feared that such struts would be aesthetic and ergonomic Disadvantages, but it has become clear during the course of the development work that this does not have to be the case.
  • the struts absorb a large part of the forces acting on the seat shell from the backrest, whereby they are subjected to tension. Thanks to the two struts, the connection between the rear wall and seat is relieved and can therefore be dimensioned with a correspondingly low material thickness. This leads to considerable material and weight savings. If the chair does not have an armrest, the struts are also valued as a stand-up aid.
