Dabei greift das U-förmige Ende des Führungshebels 12 nun über den Teilrahmen 1e, so dass der Sitzträger 14 in dem Teilrahmen 1e ausgerichtet ist. Fig. 3 shows the folding device in the sitting position.
The head-side sub-frame 1e is folded over and the support leg 10 is thus in a horizontal position. The backrest support 13 now points upwards. On him the backrest cushion 41 is attached.
The seat support 14 is aligned over the guide lever 12, which engages with its U-side end on the sub-frame 1e in this and parallel to this. The seat cushion 40 now provides a horizontal seat that extends to the backrest cushion 41.
The sub-frames 1c and 1e are horizontal one above the other and are connected to each other by means of the sub-frame 1 d via the joints 32 and 33.
The handlebar 7 has transmitted the folding movement of the subframe via the joints 30 31 and 27 on the angle lever 8. This has the support leg 10, which is fixed to the mounting plate 9 and the joint 22 on the sub-frame 1e, pivoted to the horizontal position. This movement was transmitted by means of the eccentric 26 and the guide lever 12 via the joints 23 and 24 on the parallel guide of the seat support 14. In this case, the U-shaped end of the guide lever 12 now engages over the subframe 1e, so that the seat carrier 14 is aligned in the subframe 1e.

  1. Seat-bed folding frame consisting of a support rack (2) with a lifting device(A) supported at its sides, which carries a bed frame consisting of several articulated partial frameworks (1a-1e), with one supporting leg (10) hinged at each side, at which a seat support (14) and a backrest support (13) with a folding device (B) are mounted, whereby three of the partial frameworks (1a-1e) are connected on both sides by means of coupling elements (12, 8, 7, 6, 5a, 5b, 4), forming three four-bar linkages and, as a whole, a kinematic chain, in such a manner that these partial frameworks (1a-1e) can be folded continuously from a couch position into a seat position, at approximate 90° angles to each other,
    and whereby in the seat position the supporting leg (10) is folded in an approximately horizontal position and the backrest support (13) is approximately vertical, characterised in that the seat support (14) is connected with the partial framework at the head of the bed (1e) via retaining rods (11) and with the support leg (10) via a guide lever (12) in such a way that, controlled by an eccentric (26), in the couch position it is placed underneath the partial framework at the head of the bed (1e), shifted towards the rear, and in the seat position it is aligned on the partial framework at the head of the bed (1e).
  2. Folding frame according to claim 1, characterised in that the eccentric (26) is fixed at the support leg (10).
  3. Folding frame according to claim 2, characterised in that the support leg (10) with the eccentric (26) is supported on the partial framework at the head of the bed (1e) by means of a mounting plate (9) in an eccentric hinge.
  4. Folding frame according to claim 3, characterised in that the folding movement of the partial frameworks (1d, 1e) from the couch position to the seat position is transmitted directly onto the support leg (10) by means of links (7, 8) and the eccentric (26).
  5. Folding frame according to claim 1, characterised in that the seat support (14) is pivoted on both sides of the partial framework at the head of the bed (1e) by means of respectively two retaining rods (11), which results in a parallel guide.
  6. Folding frame according to claim 1, characterised in that in each case the parallel guide is created by means of a guide lever (12) between a support rod (11) and the eccentric (26).
  7. Folding frame according to claim 5, characterised in that the guide lever (12) is connected to the centre of the support rod (11) with an u-shaped end, and with the other end is articulated at the eccentric (26).
  8. Folding frame according to claim 1, characterised in that the backrest support (13) is fixed at the support leg (10).
