Pedal support with coupled functions

A pedal box for a motor vehicle, comprising a clutch pedal (1), a brake pedal (2) and an accelerator pedal (3) that are mounted to respectively rotate about first, second and third pivots (X1, X2, X3) that are parallel to one another, said clutch pedal (1), brake pedal (2) and accelerator pedal (3) at each moment adopting either a rest position, or a position of maximum actuation, or an intermediate position somewhere between the rest position and the position of maximum actuation, and means for applying an elastic torque in a first direction of rotation (S1) to urge said clutch pedal (1) toward a first rest position, said brake pedal (2) toward a second rest position and accelerator pedal (3) toward a third rest position, characterized in that said means for applying said elastic torque comprises, a first link (4) located between said accelerator pedal (3) and the brake pedal (2) that places the brake pedal (2) in an intermediate position or said second rest position depending on whether or not the accelerator pedal (3) is in said third rest position, said brake pedal (2) having a lower lever arm (21) that extends between said second pivot (X2) and a brake pad (20), said accelerator pedal (3) having an lower lever arm (31) and an upper lever arm (32) that extend one on each side of said third pivot (X3), said lower lever arm (31) bearing an accelerator pad (30), and said first link (4) having a first finger (41) borne by said upper lever arm (32) of the accelerator pedal (3) that is parallel to the third pivot (X3) that transmits to said lower lever arm (31) of the brake pedal (2) a torque tat is directed in the opposite direction to the first direction (S1) when the accelerator pedal (3) is in said third rest position.
