Description of the Invention: [Technical Field of the Invention] The present invention relates to a locomotive seat cushion opening mechanism. [Prior Art] A conventional locomotive seat cushion opening mechanism, as shown in FIG. 1G and FIG. n, the seat cushion 902 is pivotally connected to a hinge at the upper edge of the front end of the storage compartment, and the seat cushion 902 is hinged. The other end of the 92〇 is connected with a fastening member 930. The fastening member 930 can be engaged with a lock (not shown) disposed at a position opposite to the storage box 903 to lock the seat as a rider. To open the seat cushion 9〇2 for baggage handling, first unlock the lock hook, then hold the appropriate part such as the rear part of the seat cushion 902 and apply upward force to open the seat cushion. The seat cushion 902 is normally opened to the fully open position to free up both hands for baggage retrieval. In order to maintain the seat cushion 902 in the fully open position, it will not fall in the closing direction due to its own weight. When the full opening, the center of gravity of the seat cushion 902 must exceed the lead line passing through the pivot center of the hinge 920 and the opposite side when in the closed state. . At this time, the fully open state of the seat cushion 2 is maintained by the front end portion 940 of the seat cushion 902 abutting against the front side J of the storage box 9〇3. As shown in FIG. 11, the hinge 920 is screwed to the storage box 903 by bolts 913. Generally, the storage box 9〇3 is made of a plastic material, and the point of application is given when the seat cushion 902 is in the fully open position. The distance to the chain is much larger than the distance from the abutment point to the hinge 920. If the seat cushion 9 〇 2 is applied, the force is excessively applied, and the lever 920 will be multiplied by the hinge 920 (ie, the distance from the point of application to the hinge 920 / The force of the above-mentioned urging force from the point of contact to the hinge 92 容易 is prone to cause fatigue of the hinge 920 itself or the hinge 920, and the seat cushion is loosened. On the other hand, when the seat cushion 902 is in the fully open position, even if the center of gravity of the seat cushion 902 exceeds the lead straight line passing through the center of the hinge 92, it does not fall in the closing direction due to its own weight, but it may still be because The front handle 9〇5 rotates into the seat cushion 9〇2 and the like, so that the center of gravity of the seat cushion 9〇2 returns to the same side when the closed state is caused, and the seat cushion 9〇2 is undesirably closed, causing the rider to Inconvenience in operation. Although there are components such as gas-moving rods to prevent: the seat cushions fall, but these components must be installed separately and these components are more expensive. Furthermore, in order to lock the seat cushion 9〇2 in conjunction with the fastening member 93 of the seat cushion 902, a lock hook must be separately provided at a position opposite to the fastening member 93〇 of the storage box, resulting in an increase in the number of parts. The installation # industry is complicated, and the 2 lock hooks are separately installed on the plastic material storage box 9〇3, and the overall strength of the lock mechanism will be poor. =, as described above, in order to maintain the seat cushion 9〇2 in the fully open position, the center of gravity of the seat cushion 9G2 must be beyond the opposite side of the closed state through the straight line in the pivot of the hinge 920, and by The seat cushion 9〇2刖 end 940 abuts against the front side of the compartment to maintain the fully open state of the seat cushion 2. However, in this way, the abutment point of the seat cushion 902 is rotated from the position of the closed state of the seat cushion 902 to the position of the fully open position of the seat cushion 9〇2 with the pivot of the hinge 92〇 as the center. On the line, there must be no obstacles (4) body structure. This condition imposes restrictions on the design of the car body. Especially for large-sized models, in order to overcome the problem that the integrated seat cushion is too long and too heavy to cause the ride to be “easy to open, the seat can be divided into front and rear independent 131499.doc 201000351. When the rear seat cushion is opened to the rear of the locomotive, the trajectory line of the abutment point is more likely to interfere with the rear seat grip, which causes a limitation on the design of the vehicle body.
