1. A vehicle seat with an upper seat part (2, 3) comprising a seat part (2) and a backrest (3) and a lower seat part (11), wherein a height-adjustable seat frame (4) with at least two scissor arms (5, 6) connected to each other in a rotatable manner is arranged between the upper seat part (2, 3) and the lower seat part (11), characterized in that at least one first end (5a, 6a) of at least one of the scissor arms (5, 6) is connected to at least one slide element (12) for the displacement of the first end (5a, 6a) along at least one guide rail (7), wherein the slide element (12) is at least one substantially cuboidal element (12), which slides with at least two mutually opposed first surfaces (18) along sliding faces (13a, 13b) of the guide rail (7) characterized in that each first surface (18) has a flat first face (14a, 14b) situated in a central region of the first surface (18) and at least one flat or curved second face (16a, 16b) situated proximal to the first end (5a, 6a) of the scissor arm (5, 6) and at least one flat or curved third face (15a, 15b) situated distal to the first end (5a, 6a) of the scissor arm (5, 6), wherein the first, second and third faces are arranged linearly, wherein one of the faces (37a, 37b, 38a, 38b) is arranged in such a way that in an angular setting of the slide element (12) a sliding on said face (37a, 37b, 38a, 38b) will take place, and wherein second surfaces (19) which are arranged in the front and the rear of the slide element (12) and substantially perpendicular to a longitudinal axis of the guide rail (7) have a similar shape to the first surfaces (18). 2. The vehicle seat according to claim 1, characterized in that the second face (16a, 16b) extends sloping from the first face (14a, 14b) towards a first end (18a) of the first surface (18). 3. The vehicle seat according to claim 2, characterized in that the third face (15a, 15b) extends sloping from the first face (14a, 14b) towards a second end (18b) of the first surface (18). 4. The vehicle seat according to any one of claim 2, characterized in that at least one of the first, second and third faces (14a, 14b; 15a, 15b; 16a, 16b) has a sloping face (31a, b; 32a, b; 33a, b) starting from the central region of the face (14a, b; 15a, b; 16a, b) towards edge regions of the first surface (18) of the slide element (12). 5. The vehicle seat according to any one of claim 2, characterized in that the second and third faces are arranged in the form of flat faces (15a, b; 16a, b) with an angle (34) in a range of from 0.05° to 5.0° with respect to a plane of the sliding face (13b) of the guide rail (7). 6. The vehicle seat according to claim 1, characterized in that each first surface (18) has two flat faces (37a, 37b; 38a, 38b) which extend sloping from a central region of the first surface (18) towards a first and second end (18a, 18b) of the first surface (18). 7. The vehicle seat according to claim 6, characterized in that the flat faces (37a, 37b; 38a, 38b) are arranged at an angle (39) in the range of from 0.1° to 15.0° with respect to a plane of the sliding face (13b) of the guide rail (7). 8. The vehicle seat according to claim 1, characterized in that the slide element (12) is connected in a rotatable manner to the first end (5a, 5b) of the scissor arm (5, 6) by means of a shaft which extends perpendicularly to the guide rail (7) and which is arranged in a recess (17) in the slide element (12). 9. The vehicle seat according to claim 1, characterized in that the guide rail (7) has a U-shaped cross-sectional profile within a plane (B-B) perpendicular to a longitudinal direction of the guide rail (7).
