  • the two end plates 32, 34 are via a hinge 36 interconnected, and the space between the two end plates 32, 34 is through a layer of material 38 filled in, the plate-shaped geometry and out rubber-elastic material, which is typically can have a Shore hardness of about 70 °.
  • the fat in practice the material layer 38 is 10 to 20 mm.
  • the hinge 26 includes a first end plate 40 which over a countersunk screw 42 with the back part 28 firmly connected is.
  • a second end plate 44 of the joint 26 is via a second countersunk screw 46 with a upper joint receiving portion 48 of the backrest support 24 connected.
  • the joint 18 is a uniaxial joint, the axis of which is through the hinge 36 is predetermined. This axis runs in the given horizontal direction would be right Edge contour of the seat part 20 parallel to the front edge of the seat and parallel with the flat geometry of the backrest part 28 to the backrest surface.
