Patent ID: 8360524

Claim:
A vehicle seat including parts for carrying out a vibratory movement, which parts comprise the following: a base part, a top part, spring mounted relative to the base part, a height adjustable connection frame arranged between the base part and the top part comprising at least one first frame arm, at least one second frame arm and at least one spring element attached at one end to one of the frame arms and at the other end to the base part or the top part, at least one position-variable first point of attachment for connecting at least one of the frame arms to the base part and/or the top part in order to cause a variable motion sequence, characterized in that the first point of attachment constitutes an excenter element connected to an end of the frame arm and attached to the base part or the top part, its various excenter positions cause a lever change of the frame arm disposed between the base part and the top part, and a motion sequence of the parts, which can be carried out in a vibration condition by applying a constant force onto the base part and/or the top part, can be varied in a further vibration condition by applying a variable force onto the base part and/or the top part.
