Abstract
A vehicle seat is provided, in particular a commercial vehicle seat, having a scissor-type stand (3) that can vibrate and comprises a bottom frame (5), a top frame (7), two first rocker arms (8a) and two second rocker arms (8b) that intersect in pairs at a scissor axis (10) extending in a transverse seat direction (y). At least one first rocker arm (8a) is supported at one end by at least one bearing mechanism (20) on the top frame (7) or on the bottom frame (5) so as to be able to rotate and vibrate in the longitudinal seat direction (x). The at least one bearing mechanism (20) has at least one damping spring (26), which elastically absorbs and dampens vibrations in the longitudinal seat direction (x).

16. A vehicle seat comprising:
-
a bottom frame; a top frame; two first rocker arms; two second rocker arms, one of the first rocker arms intersecting with one of the second rocker arms to form an intersecting pair with a scissor axis extending in a transverse seat direction and another of the first rocker arms intersecting with another of the second rocker arms to form another intersecting pair with a scissor axis extending in a transverse seat direction, the bottom frame, the top frame, the two first rocker arms and two second rocker arms forming a scissors-type stand that can vibrate; and a bearing mechanism supporting at least one of the two first rocker arms on the top frame or on the bottom frame so as to be able to rotate and vibrate in a longitudinal seat direction, the bearing mechanism having at least one damping spring elastically absorbing and dampening vibrations in the longitudinal seat direction. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24)

34. A commercial vehicle seat comprising:
-
a bottom frame; a top frame; a first side first rocker arm; a second side first rocker arm; a first side second rocker arm; a second side second rocker arm, the first side first rocker arm intersecting with the first side second rocker arm to form a first side intersecting pair with a scissor axis extending in a transverse seat direction and the second side first rocker arm intersecting with the second side second rocker arm to form a second side intersecting pair with a scissor axis extending in a transverse seat direction, the bottom frame, the top frame, the first said second side intersecting pair and the second side intersecting pair forming a scissors-type stand that can vibrate; a transverse tube connecting an end of the first side first rocker arm to the second side first rocker arm; and a bearing mechanism supporting said transverse at least one of the first side first rocker arm and second side first rocker arm on the top frame or on the bottom frame for rotation and vibration in a longitudinal seat direction, the bearing mechanism having at least one damping spring elastically absorbing and dampening vibrations of the one of the first side first rocker arm and second side first rocker arm in the longitudinal seat direction.
