Abrégé

One embodiment of a bidirectional pedal assembly includes a base structure connectable to a vehicle structure and a pedal support member pivotally mounted on the base structure to be pivotable around an axis of rotation from a rest position in a first direction and in a second direction opposite to the first direction. First and second spring elements to urge the pedal support member to its rest position. First and second frictional mechanisms are disposed between the pedal support member and the first and second springs, such that the first and second frictional mechanisms, respectively, moves with the pedal support member and transmits force from the pedal support member to one of the first and second spring elements. Each frictional mechanism is arranged to increase a frictional resistance to retard pivotal movements of the pedal support member upon force being transmitted through the respective frictional mechanism.

Abrégé

The present invention provides a bidirectional pedal assembly comprising: a base structure (2) connectable to a vehicle structure; a pedal support member pivotally mounted on the base structure to be pivotable around an axis of rotation from a rest position in a first direction and in a second direction opposite to the first direction; first and second spring elements (20, 40) which are tensioned when the pedal support member is pivoted in the first and second direction, respectively, and which urge the pedal support member to its rest position; characterized in that a first (24, 26, 28) and a second frictional mechanism (44, 46, 48) is disposed between the pedal support member and the first and second springs, respectively, such that, when the pedal support member is pivoted in the first and second directions, one of the first and second frictional mechanisms, respectively, moves with the pedal support member and acts on one of the first and second springs, respectively, by transmitting force from the pedal support member through one of the first and second frictional mechanisms, respectively, to one of the first and second spring elements, and in that each frictional mechanism (24, 26, 28, 44, 46, 48) is arranged to increase a frictional resistance to retard pivotal movements of the pedal support member upon force being transmitted through the respective frictional mechanism.
