An arrangement for permitting retraction of a vehicle foot pedal, operable o n a conventional push rod (14) of a brake booster or a clutch, in a frontal cras h of sufficient magnitude, comprises a rotary member (1) attached to, and mounted on a blade (13) of the foot pedal for free rotation about the picot, and adapted to be coupl ed to the push rod (12). The rotary member (1) has a decoupling feature (3-8) that is not activated during normal operation of the foot pedal, and displacement means (10, 11) i s provided to cause partial rotation of the rotary member (1) upon a frontal impact of sufficient magnitude, to stress the decoupling feature (3-8) until a threshold value is reached whereupon the decoupling feature (3-8) is activated, thereby disconnecting t he push rod (14) from rotary member (1) and hence from the blade (13) of a foot pedal, t o permit free pedal movement. |
