Abstract:
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 ( 5 a , 6 a ) 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 ( 5 a , 6 a ) 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 ( 13 a , 13 b ) of the guide rail ( 7 ) characterized in that each first surface ( 18 ) has a flat first face ( 14 a , 14 b ) situated in a central region of the first surface ( 18 ) and at least one flat or curved second face ( 16 a , 16 b ) situated proximal to the first end ( 5 a , 6 a ) of the scissor arm ( 5 , 6 ) and at least one flat or curved third face ( 15 a , 15 b ) situated distal to the first end ( 5 a , 6 a ) of the scissor arm ( 5 , 6 ), wherein the first, second and third faces are arranged linearly, wherein one of the faces ( 37 a , 37 b , 38 a , 38 b ) is arranged in such a way that in an angular setting of the slide element ( 12 ) a sliding on said face ( 37 a , 37 b , 38 a , 38 b ) 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 ).
