Controllable folding seats

The invention relates to a folding seat for a passenger compartment of a vehicle.

Furthermore, the invention relates to a vehicle, in particular a rail vehicle.

DE 10 253 186 A1 describes a folding seat with a seat surface which is bounded on both sides by a frame construction. Below the seat, a drive element is arranged, which brings the seat in the one or unfolded state. Furthermore, retaining elements are provided which hold the seat at one end both in the folded state and in the unfolded state in the frame construction. The drive element is arranged stationary and the seat corresponds in the folded state of the height of the frame construction or surmounted the frame construction.

A folding seat of the aforementioned type has become known for example from DE 4 324 882 A1. This document shows a folding seat, in particular for public transport, with a hinge to be fastened to a wall, a return spring and a stop, which transmits the torque of a folded down seat on the wall, wherein the hinge is a wall-mounted mounting bracket, one on the Seat fixed bearing block and has a mounting and bearing block penetrating, horizontally and parallel to the wall extending shaft. Such folding seats commonly used as a reserve or emergency seats are often mounted in the entry and / or transit areas of public transport, such as passenger train, tram and subway cars. The return spring pivots an unloaded seat surface into a vertical position against the wall, while the stopper is typically a portion of the seat bottom surface resting on a wall projection and transmits the torque of a folded down, loaded seat to the wall.

Conventional folding seats are usually only used as soon as all normal seats are occupied. However, once a folding seat is used, it limits the available standing area like a normal seat. A passenger capacity increase by more standing space is therefore no longer possible.

It is therefore an object of the invention to provide a folding seat, with which it is possible to optimally exploit the passenger capacity of the vehicle and without significant restriction of comfort for the passengers.

This object is achieved with a folding seat for a passenger compartment of a vehicle according to the invention in that it has a controllable drive for high and low folding a main seat, said folding seat at a front edge of the main seat a projecting from the main seat, in a folded state of the main seat as Anliehnhilfe provided extension has.

According to the invention, the seats of folding seats or groups of seats can be specifically centrally controlled (folded up or down) by an electric, mechanical or pneumatic drive. In contrast to a conventional folding seat is a targeted central control or a change in function from "normal seat" to "Lehnhocker" (with folded seat) and the associated increase in passenger capacity with only slight loss of comfort possible. A change of seats may, at the discretion of the operator, e.g. with increased passenger traffic (rush hour) in a final stop, depot or any passagesslosen state of the vehicle done.

According to an advantageous variant of the invention, end positions of the main seat surface in a raised or lowered state can be fixed by means of a lock. The respective seat position in the end position can not be changed by a passenger and is at the discretion of the operator of the rail vehicle.

Furthermore, the main seat surface and the extension may be formed as a structure having an L-shaped cross section. This has the advantage that, when the main seat surface is raised, the extension is automatically brought into a position in which it can serve as a leaning support for a person.

The above object can also be achieved with a vehicle of the type mentioned, in which according to the invention folding seats, which are designed according to one of claims 1 to 3, are arranged, wherein the drives and locks the folding seats are centrally actuated.

The invention together with further advantages will be explained below with reference to some non-limiting embodiments, which are illustrated in the drawing. In this show:

Figure 1 is a front view of a folding seat according to the invention;

2 shows a first view of a section along the line A-A in FIG. 1 and FIG. 3 shows a second view of a section along the line A-A in FIG. 1.

According to FIG. 1, a folding seat KLA according to the invention has a controllable drive ANT for raising and lowering a main seat HAU. The drive ANT is arranged below the main seat HAU and may preferably be designed as a per se known electric drive or electromechanical actuator. By using an electromechanical drive ANT, a particularly simple and cost-effective embodiment can be achieved.

In order to protect the drive ANT against damage by unauthorized high or low flaps of the main seat, a locking VER is provided, with which the position of the main seat can be fixed in a high or low folded state.

The locking VER can be designed, for example, as an electromechanical lock. Thus, the lock VER may be formed by means of a coil arranged in a bolt, which are dependent on a magnetic field generated by the coil in the respective end position of the folding seat KLA with a corresponding stationary counterpart, such as a bore, engaged or released from this again can. In principle, however, any type of releasable locking can be selected in order to fix the folding seat in its end positions.

At a front edge of the main seat HAU a projecting from the main seat HAU extension FOR is provided. As shown in Figs. 2 and 3, the main seat surface HAU and the projection FOR are formed as a structure having an L-shaped cross section. The extension FOR serves in a folded-up state of the folding seat KLA as a leaning for a passenger.

An inventive vehicle, in particular a rail vehicle, has a passenger compartment with a plurality of folding seats KLA of the type described above. The drives ANT and locks VER of the folding seats KLA are according to the invention centrally, for example by means of a corresponding arranged in a driver's control unit, electrically or electronically operated or controlled. The capacity of the vehicle with its unalterable dimensions can be specifically controlled by the operator, depending on the number of passengers. By increasing the ratio standing room to seat capacity is controlled. This is done through the controlled " conversion " from the folding seat in a standing room with lean-on help, the lean-to help to improve comfort for the passengers contributes.
