Back support links are provided which are rotatable around a rotary axis in the frame, parallel with the support beams, and arm supports are directed across the support beams. A number of seat cushion sections are provided, combinable to form individual seats and a number of pack support sections (5-16, 21-28) are reciprocally combinable by use of connecting components (17) to form individual back supports, so that at least one group is produced, having seats with selected identical seat width. |
