Abstract

Device for absorbing impact energy for a door of a motor vehicle, the door being in the form of a hollow box in which is arranged a glass panel (12) capable of sliding between a lowered position and a raised position, the absorbing device (30) being arranged in a lower region of the box and comprising two shock-absorbing blocks (32, 33) defining a passageway for the glass panel (12) therebetween. The device comprises movable members (39) for mechanical connection which are arranged between the shock-absorbing blocks (32, 33), the members (39) each assuming an active position, in the absence of the glass panel, in which they ensure mechanical continuity between the blocks (32, 33) and constitute a supplementary component for absorbing impact energy, and moving out of the way to assume an inactive position when the glass panel passes through.
