A folding and positioning device for tier-seats comprising several linked seats 1 in the same row with their pedestals 3. At least one rotational leg 2 is fixed in the middle on the rotational shaft 7 on the upper front side inside the pedestal, its upper end fixed on the seat 1 and the lower end having a step. In the lower rear inside the pedestal is another rotational shaft 5, on which is fixed a bracketing arm 6 in the position corresponding to the rotational leg 2. When the seats are being erected to their upright position, the free end of the bracketing arm 6 abuts against the step at the lower part of the rotational leg 2. Compared with conventional technologies, the present invention calls for very little force in order to erect or lay down the seats. Furthermore, the seats in the entire row are linked joint motion, thus greatly enhancing the efficiency.
A folding and positioning device for tier-seats comprising several seats (1) with their pedestals (3) mounted in the same row, characterizing in that the respective seat (1) are linked up as a whole and there is at least one rotational leg (2), which is fixed in the middle on a rotating shaft (7) located at the front upper part of the interior of the pedestal, the upper end of the rotational leg is fixed on the seat (1) and a step is provided on its lower end, another rotating shaft (5) is provided at the lower rear part in the pedestal, on which a bracketing arm (6) is fixed in the position corresponding to the rotational leg (2), when the seats are in an unfolded and positioned state, the free end of the bracketing arm (6) abuts against the step at the lower end of the rotational leg (2).
