Device for guiding two sub-assemblies of a motor vehicle which are displaceable in relation to one another, in particular of a motor vehicle seat, in a guide direction

A seat frame comprising a device for guiding two seat sub assemblies of any one of a motor vehicle and a motor vehicle seat, the subassemblies being displaceable relative to each other along a guide direction, the device comprising:

• two guide elements spaced apart from one another in a transverse direction perpendicular to the guide direction and;
• two guide devices in each of which one of the guide elements is mounted movable along the guide direction;
• wherein one of:
• (a) the guide elements are coupled to one another, (b) the guide devices are coupled to one another, and (c) the guide elements and the guide devices are coupled to one another, and stops are associated with the guide elements on the guide devices to restrict movement of the guide elements relative to the respective guide devices along the transverse direction perpendicular to the guide direction;
• wherein a first of the two guide elements is mounted in the associated guide device with a small displacement margin perpendicular to the guide direction, wherein the displacement margin is configured such that a relative movement of the guide element and the associated guide device is possible in the guide direction and a substantial relative movement is prevented along the transverse direction;
• and
• wherein the second guide element is mounted with greater displacement margin than the displacement margin of the first of the two guide elements along the transverse direction in the associated guide device.
