Abstract

Apparatus and methods are provided for the activation of a safety device associated with a vehicle pedal in a vehicle including an engine compartment, a pedal arm, a push rod connected to the pedal arm, and an acting rod for acting upon the push rod, the apparatus comprising an actuator for releasing the push rod from the pedal arm upon actuation thereof, and a sensor for actuation of the actuator in response to detection of a condition of the vehicle corresponding to a collison, the sensor being disposed in a zone within the vehicle defined by first and second distances displaced from the front edge of the vehicle, these distances being selected whereby the zone defines a location in which deformation occurs upon a collision at a predetermined speed and corresponding to minimum and maximum time delays for activation of the sensor after deformation of the vehicle.
