Bilaterally effective drive mechanism

A vehicle seat assembly comprising:

• a vehicle seat having a shaft;
• and
• a two-way drive for producing a rotation movement comprising:
• a drive lever having a first drive direction away from a zero position and a second drive direction opposite the first drive direction away from the zero position;
• a return spring for returning the drive lever to its zero position;
• a fixed casing catch coupled to the return spring;
• and
• a return catch coupled to the drive lever,
• at least two friction locked components positioned on the shaft and coupled to one another, wherein the friction locked components are connected to the drive lever in at least one of a friction locked way and a shape locked way;
• wherein upon movement of the drive lever away from a zero position, in association with the return spring which acts as an elastic switching component, the friction locked components engage with the shaft and on a drive side transfer a torque to the shaft,
• wherein the return catch is directly secured to one of the friction locked components;
• and
• wherein the shaft that is to be driven is only rotated when the drive lever moves away from the zero position, whereas when the drive lever moves in the direction of the zero position the shaft is not moved.
