A detector is provided for a safety arrangement in a motor vehicle, adapted to detect an impact between the bumper 4 of the vehicle and an object 7 such as a pedestrian. The detector arrangement includes sensors 8,9 such as two accelerometers, which sense the acceleration of the bumper. Calculating means 10-14 analyses the sensed acceleration to determine if the sensed acceleration is below a predetermined value, and a signal generator 15 generates a signal to trigger the safety device if the acceleration is below the predetermined value. |
