摘要 | PURPOSE: An automatic folding apparatus for a seat of an electric rail car is provided to make the best use of space and to improve transport efficiency and convenience by folding the passenger seat with operating a hydraulic or pneumatic cylinder through remote control. CONSTITUTION: A backrest(20) of a seat is placed perpendicularly to a lower plate(21) of the seat in a connecting portion, and combined with the lower plate by a rotating plate to fold or unfold the lower plate. A driven gear(30) is fastened at the side of the rotating shaft, and a rack(41) is combined with the end of a hydraulic or pneumatic cylinder(40). The hydraulic or pneumatic cylinder is reciprocated linearly by using compressed air of hydraulic pressure from an electric rail car. The lower plate is folded or unfolded against the backrest by turning the driven gear engaged with the rack. | ||||||
