1. A vehicle seat for preventing submarining of a passenger on the vehicle seat in the case of an accident-induced deceleration, comprising:

  • a seat section having two seat side sections extending in the longitudinal direction of the vehicle, wherein the two seat side sections support a padding which defines a seat surface;

    a padding support disposed between the two seat side sections which is provided beneath the padding; and

    a restraint device that can be set in a retracted inactive position and in an extended active position, wherein the restraint device is positioned between an upper surface of the padding support and a lower surface of the padding and at a distance from the seat side sections, such that the restraint device is fastened exclusively to the padding support by at least one of pushing, sliding, clipping, or adhesively adhering the restraint device thereto, such that the restraint device is an add-on element which can be selectively integrated into the vehicle seat;

    said restraint device equipped with a reversibly operating actuator, said actuator arranged between the padding support and the padding, or is supported between the padding support and the padding, and operation of the actuator is provided before the existence of an accident-induced deceleration of the vehicle seat;

    said restraint device further equipped with a plate form positioning element which is movable by the actuator;

    said positioning element adjustable by the actuator from a retracted position which corresponds to the inactive position of the restraint device into an extended position which corresponds to the active position of the restraint device;

    said positioning element providing for a rotation around an essentially horizontally extending axis between the retracted position and the extended position of the positioning element;

    said positioning element rotation around the essentially horizontally extending axis is provided as a rotation in the direction of travel of the vehicle seat wherein a rotation of at least one part of the positioning element around an essentially vertically extending axis is provided between the retracted position and the extended position of the positioning element, and said positioning element is a telescopically extendable positioning element.
