ABSTRACT:
A vehicle seat which is adjustable both with regard to its height and angle of inclination has front and rear height mechanisms which can be operated independently of one another. Each of the height adjustment mechanisms has at least one lever, which levers are pivotable about an axis running in the lateral direction of the seat. The upholstery support of the seat is supported on support points of these levers, which lie at a distance from their pivot axes. The front and rear height adjustment mechanisms are connected with a coupling drive, which, when the front height adjustment mechanism is activated limits the height adjustment of this front height adjustment mechanism, and when the rear height adjustment mechanism is activated, the height adjustment of the support point thereof is transferred to the support point of the front height adjustment mechanism.
