In this way, the seat adapter can be mounted in a simple manner with the motor vehicle floor via the track units. 
         [0007]    Preferably, the seat adapter has a suitable mount for at least one individual seat. Preferably, several mounts are provided for the collective fastening of several individual seats on the seat frame. For example, the motor vehicle seat can be arranged movably via the seat adapter, in particular displaceably longitudinally on the motor vehicle floor. 
         [0008]    Here, the direction indication: “longitudinally” corresponds to a direction of travel of a vehicle. The corresponding track units are pre-mounted on the seat adapter. The track guide is preferably connected with the motor vehicle floor. The respective track slide is arranged movably in the corresponding track guide. Through the solution described above, several individual seats are mounted on a displaceable equipment carrier. The individual seats are, furthermore, foldable individually to a loading floor or respectively to a sitting part. The floor fastening takes place via the seat adapter, so that not every individual seat must be fastened to the motor vehicle floor. Hereby, a saving can be made with regard to connecting means such as screws. The individual seats are, in addition, longitudinally displaceable collectively, so that an additional storage space is able to be used underneath the individual seats, for example for a spare wheel. In addition, an assembly optimization is ensured. Through the pre-mounted seats on the equipment carrier, no individual seats have to be supplied on the line. The seat frame is fixedly connected with the track slide.

The seat frame is preferably constructed as a framework construction or respectively as a seat framework, for example with several lattice-like beams. Preferably, the seat framework spans a plane on which a seat structure of a motor vehicle seat rests or several seat structures of several motor vehicle seats rest. The framework construction is particularly well suited for pre-stages of manufacture before the mounting with the motor vehicle floor. In particular, the framework is able to be handled easily, for example during the fastening of the individual seats on the framework or respectively on the framework construction. 
         [0010]    Another embodiment includes that the seat framework has at least one longitudinal beam per track unit. Preferably, the seat framework has two parallel longitudinal beams spaced apart from one another. The longitudinal beams are constructed as a lateral boundary. The longitudinal beams extend here in the direction of travel of a motor vehicle. The longitudinal beams are preferably connected fixedly with the associated track slide. 
         [0011]    Another further embodiment includes that the respective longitudinal beam is connected with the respective track slide. The track unit and the corresponding longitudinal beam are preferably aligned in the same direction, in particular in the direction of travel. The connection is preferably constructed in a stationary and/or rotatably fixed manner. 
         [0012]    Accordingly, another embodiment includes the seat frame has two track units spaced apart from one another laterally. In an embodiment, the seat frame has at least one track unit. For example, the track unit is provided constructed centrally in the direction of travel. The track unit comprises the track guide and the track slide. The track slide moves guided along the track guide. The track guide is or becomes connected with the motor vehicle floor. The track slide is connected with corresponding parts of the seat frame, for example with the corresponding longitudinal beam. 
         [0013]    A further embodiment includes the seat framework has several longitudinal beams that are connected with one another via at least one transverse beam. Preferably, the seat framework has two parallel longitudinal beams spaced apart from one another laterally. In another embodiment, further longitudinal beams are arranged between the longitudinal beams that function as a lateral boundary, for example to support the seat structure that is received on the seat framework. At least one transverse strut or respectively one transverse beam is provided for the construction of the framework. 
         [0014]    Preferably, two transverse struts are provided, which connect the ends of the longitudinal beams with at least one other longitudinal beam, preferably its ends.
