    However, to adjust these seats in height, in particular when lifting in a loaded state, it is necessary to apply a large torque. The magnitude of the torque decreases as the seat rises, but this adversely affects when manually changing the seat position, since the angle of rotation of the drive Even is limited, and the control elements are small.
    The purpose of the invention is to improve the usability of the seat by ensuring the constancy of the drive and torque when regulating it.
    This goal is achieved by the fact that the seat is equipped with additional curved levers rotatable in a vertical plane, each of which is fixed at one end to the base of the seat by a hinge that is offset from the hinge of the base lever, and the other end is pivotally connected to the frame arm, while the gear sector is connected with the last lever, mounted on its end, opposite the hinge of fastening the curved lever.
    The distance between the mounting points of each additional bent lever on the base and frame levers is equal to the distance between the mounting points of the corresponding levers to the frame and base.
    • The distance between the points of attachment of each lever to the frame and the base is equal to the distance between the point of attachment of the frame lever and the point of attachment of the additional curved lever on it. fifteen
    With this embodiment of the seat for its height adjustment requires minimal effort.

    The invention relates to a transport engineering, in particular, to height-adjustable seats, and can be used in vehicles and, in particular, in automobiles. Vehicle seats are known, adjustable in height and containing a pivotal support in the vertical plane, connected by one shoulder to the base by means of sub axles and the other by means of the seat cushion frame arms 1. The disadvantage of this seat is that The seat cushions with the base do not provide a constant rotational moment when the seat changes its height, and therefore the force required to lift the seat also changes. Closest to the present invention is a height-adjustable car seat containing a seat cushion with backrest fixed to the frame, a base connected to the frame by means of the frame arms and the base provided with drive links, and kinematically connected to the frame levers and the base corresponding gear sectors interlinked in pairs with C2. However, to adjust these seats in height, in particular when lifting in the laden condition, it is necessary to apply a large torque. The torque value decreases as the seat rises, but this adversely affects when the seat position is manually changed, since the angle of rotation of the drive link is limited, and the adjustment elements are small. The purpose of the invention is to increase the ease of use of the seat by ensuring the constancy of the drive and torque moments when it is adjusted. This goal is achieved by the fact that the seat C is filled with additional curved levers, each of which is one, pivoting in the vertical plane. the end is fixed on the base of the seat by means of a hinge displaced relative to the hinge of fastening the base arm, and the other end is hinged to the frame arm, while the toothed sector associated with the last lever is mounted on its end, opposite the hinge of fastening the twisted arm.
