Description of the Invention: [Technical Field of the Invention] The present invention is a folding chair that is housed in a passenger compartment of a vehicle. Furthermore, the present invention also includes an automobile, particularly a rail vehicle. [Prior Art] German Patent DE 1 0 2 5 3 1 86 proposes a folding chair whose both sides of the seat surface are limited by a frame structure. Below the seat surface of the folding chair is a drive unit that moves the seat surface to an open or folded condition. In addition, the folding chair has a stop member that functions to secure the seat surface within the frame structure after the seat surface has been positioned (whether in an open or folded condition). German Patent DE 4 324 882 also proposes a folding seat of this type, in particular a folding seat for mass vehicles, having a hinge that can be fixed to the wall, a return spring, and a stop for its function. It is to transmit the torque of the seat surface folded down to the wall. The hinge is a fixed bracket that is placed on the wall, a bearing bracket that is fixed to the seat surface, and a horizontal shaft that passes through the fixed bracket and the bearing bracket and is parallel to the wall. Such folding chairs, which are often used as spare seats or temporary seats, are often placed near the doors and/or walkways of mass transit vehicles (e.g., trains, trams, subway trains). The role of the return spring is to fold the unloaded seat surface into a vertical position against the wall. The stop is usually a member below the seat surface that can be caught on a protruding portion of the wall. The function of the stop is to transfer the torque of a seat that is folded down and loaded to the wall -5 - 200808584. In general, when the normal seat is full, the passenger will start to sit on the folding chair. However, once the folding chair is opened, it will reduce the standing space for the passengers to stand like a normal seat, so there is no way to increase the passenger capacity by increasing the standing area. SUMMARY OF THE INVENTION It is an object of the present invention to provide a folding chair that can be used to optimize the passenger load without causing too much impact on passenger comfort. In order to achieve the above object, the folding chair provided in the passenger compartment of the vehicle provided by the present invention has a transmission capable of folding and folding the main seat upward, and the folding chair has a leading edge of the main seat surface. A projection that protrudes from the main seat facing outward and serves as an auxiliary support when the main seat surface is in an upwardly folded state. In accordance with the present invention, an electric, mechanical, or pneumatic transmission can be used to centrally control (fold up or fold down) the seat surface of the folding chair or seating area. Different from the general folding chair, the present invention can change the seat from the "normal seat" to the "backrest high chair" (the upwardly folded seat surface) in a centrally controlled manner, while only losing a little comfort. In the case of sex, the purpose of increasing the passenger capacity is achieved. The transport unit can perform the above-mentioned change work according to the operation of the vehicle (for example, the commuting time of passengers) when the terminal, the stop, or when there is no passenger in the trunk. According to an advantageous embodiment of the invention, the primary seat surface can be held in the final position of the upwardly folded or folded down state by means of a locking device. The passenger does not change the final position of the seat by himself. Instead, the operating unit of the rail vehicle determines the final position of the seat. Further, the structure of the main seat surface and the convex portion can be designed to have an L-shaped cross section. This has the advantage that when the main seat is folded upwards, the projection automatically reaches a position that can serve as an auxiliary support for the passenger. In order to attain the object of the present invention, the present invention also provides a vehicle having a folding chair provided in any one of claims 1 to 3, and which can be controlled by a central control method. The transmission and locking device of the folding chair. [Embodiment] The contents and other advantages of the present invention will be further described below in conjunction with the drawings and the embodiments. The following examples are for illustrative purposes only and are not intended to limit the scope of the invention. As shown in Fig. 1, the folding chair (KLA) of the present invention has a controllable transmission (ANT) that folds the main seat surface (HAU) up 4 and down. The transmission (ANT) is located below the main seat surface (HAU) and is preferably an electric or motor-type transmission of the known art. A particularly simple and less costly embodiment of the invention is the use of an electric motor type transmission (ANT). In order to protect the transmission (ant) from being damaged by the upward folding and downward folding of the main seat surface, a locking device is provided which can hold the main seat surface in an upwardly folded or folded down position ( VER). For example, a motor type locking device (VER) can be used. The motor-type locking device (VER) consists of a screw that is placed in the coil. The 200808584 screw can be fitted with a fixed position according to the magnetic field generated by the coil at the final position of the folding chair (KLA) (eg A hole) is engaged or disengaged from the fitting. In principle, however, any form of releasable latching device can be used as a latching device for securing the inventive folding chair in its final position. A leading edge of the main seat surface (H A U) has a projection (FOR) that projects outwardly from the main seat surface (H AU). As shown in Figs. 2 and 3, the main seat surface (HAU) and the convex portion (FOR) have an L-shaped cross section φ. The projection (FOR) acts as an auxiliary support for the passenger when the main seat surface (HAU) is in the upwardly folded state. The present invention provides a vehicle, particularly a rail vehicle, in which the passenger compartment of the vehicle has a plurality of folding chairs (KLA) of the present invention as described above. The vehicle can control the transmission (ANT) and the locking device (VER) of the folding chair (KLA) in a centrally controlled manner, for example by means of an electric or motor-controlled transmission from a central control unit mounted on the bridge (ANT) ) and the locking device (VER). In this way, the transport unit can adjust the passenger capacity of the vehicle according to the number of passengers without changing the size of the trunk. For example, as long as the ratio of the station to the seat is increased, the passenger capacity can be increased. That is to say: as long as the state of the folding chair is changed from the seat state when folded down to the standing position with the auxiliary support. The state is sufficient, and the auxiliary support can also contribute a certain degree of comfort to the passenger's comfort.
