A vehicle seat fitting system includes a fitting (10) with a first and second fitting part (11, (12) to lock and rotate about an axis (A), a transfer rod which unlocks the fitting and a hand lever (5), which rotates the transfer rod to unlock the fitting. A stop module (50) is supported on the fitting to rotate about the axis and stop the hand lever and one of the fitting parts in relation to each other in a one rotational direction. The stop module has a stop (50b) and the one fitting part has a counter stop (51) that define a rotational angular range. A restoring spring (54) with spring ends (54b, 54c) preloads the stop (50b) in the direction of the counter stop. One of the spring ends is fastened to a spring mount (3b) arranged outside of the stop module in a radial direction.
