    • The invention relates to a device for adjusting the height of a motor vehicle seat, said device comprising a base element which is fixed to the seat frame, and a supporting element which is mounted on the base element in a longitudinally mobile manner and is used to support the passenger. When the supporting element is used in accordance with requirements, the weight exerts a force on the supporting element in a supporting direction. The inventive device also comprises guiding means used to guide the supporting element on the base element in a mobile manner in a direction of displacement. According to the invention, the guiding means (3, 4) comprise a first guiding device (3) on which the supporting element is supported on the base element (1), and on which the supporting element (2) and the base element (1) co-operate with play in a direction (y) perpendicularly to the direction of displacement (x) and the supporting direction (z). The guiding means (3, 4) also comprise a second guiding device (4) which is used to guide the supporting element (2) on the base element (1), essentially without play, perpendicularly to the direction of displacement (x) and the supporting direction (z).
