A transmission device (8) connects the base structure to a backrest structure (6). The transmission device enables achieving forward traction of the base structure when lifting the backrest structure rearwardly from a retracted position to a use position. Each flange has front and rear slots (13) allowing forward movement and raising of the base structure when lifting the backrest structure, where the slots are equipped with a plastic material plate. The front and rear slots respectively receive front and rear transverse metal fingers (4a, 4b) of the stretchers in a sliding manner.</p> |
