Accelerator pedal, particularly for a motor-vehicle

The accelerator pedal (1) comprises a support housing (2; 3, 4) in which there is mounted a control lever (5) rotatable about a first axis (A), from a first position to a second position, against the action of resilient opposition means (9, 10) arranged between said lever (5) and a reaction arm (12b) of a structure (12) connected to the housing (2; 3, 4) in a pivotable manner about a second axis (B) parallel to the first axis (A). The structure (12) also has a friction arm (12c) adapted to apply a friction force against the lever (5). The arrangement is such that the friction force is variable depending on the variation in the angular position of the lever (5), which is supported rotationally in the housing (2; 3, 4) about a fixed axis (A), in a stationary seat (7, 8) defined in the housing (2; 3, 4).
