The present invention relates to a vehicle brake or clutch pedal with an automatic disengagement mechanism in the event of a frontal impact of sufficient force.

BACKGROUND OF THE INVENTION Vehicle pedals with various safety mechanisms operating singly in the event of a frontal collision are known. The function of the mechanism is to protect the lower limb of the vehicle operator and in the event of a frontal collision it is necessary to prevent the pedal from moving on a sharp or dangerous scale towards the driver.

In a frontal impact where the pedal can potentially cause injury, the pedal-attached wall is deformed and the pedal support structure and the pedal itself are pushed towards the driver. In this situation, the safety mechanism must be operated to prevent the pedal from colliding against the driver's lower limb.

By separating the pedal from the servo brake or clutch push rod, it is possible to automatically move the pedal to the minimum injury position against the driver's lower limb, or to act in a mechanism to lock the pedal in the normal operating state of the pedal, A variety of alternative safety mechanisms are known.

The pedal includes a release lever for separating the connection between the pusher and the first and second members in the event of a frontal impact of sufficient force such that the second member and the pusher The above-mentioned joint coupling of the above-mentioned joints is disabled. The release lever includes a groove that has a narrow neck that is articulated with one of the members and extends into the extended area and includes a portion of the vehicle designed for minimal deformation in the case of a frontal impact of sufficient size The release lever is designed to contact and rotate the release lever to the release position.

EP 1323602 A1 discloses a brake or clutch comprising a first member comprising a shoe at its free end for the driver ' s foot and a second member articulated in such a manner that the second member is articulated to the pedal support structure, The pedal is started. The first member includes an extension on the opposite end of the pedal, the extension having a slot connected to the cross pin, the pin moving through an open hole in the second member of the pedal. A lever is mounted on the second member, one of the free ends of the lever is forked, and the lever is also connected to the cross pin. In normal operation of the pedal, the pin is received in the opening and in the slot at the same time, firmly connecting the first and second members, while the fork on the pivoting lever prevents the pin from moving. In the event of a frontal impact with sufficient force to cause deformation or displacement of the support structure of the pedal, the lever pivots and the lever moves to displace the pin to all the paths along the openings of the second member, Moves away from the slot of the first member, the first member pivots toward the support structure and moves away from the driver.
