A pedal-control device with adjustable position particularly for motor vehicles

The device comprises: a stationary support structure (2), a pedal (4) pivotable about an axis (O-O) relative to the structure, an operating lever (6) to which a control member (11) is connected and which is mounted for pivoting relative to the structure (2) and can be pivoted by the pedal (4) when the latter is pressed, and adjustment devices (3g, 3, 5) for acting on the pedal (4) in order selectively to modify its operative position relative to the axis (O-O). A rack (5) is fixed to the pedal (4) and meshes with a pinion (3g) coaxial with the axis (O-O), and restraining elements (7, 9, 10) are associated with the lever (6) and tend to hold the pedal (4) in a predetermined position relative to the axis (O-O). The arrangement is such that the pinion (3g) is normally fixed and can act as a support for the pivoting of the rack (5) and the pedal (4), and the pinion (3g) can be rotated so as to bring about a translational movement of the rack (5) and of the pedal (4) in order to adjust the operative position of the pedal.
