    a second support;

    a first arm moveable about the first support to rotate about a substantially horizontal pivot axis;

    a second arm moveable about the second support to rotate about a substantially horizontal pivot axis;

    a coupling mounted to the first arm and arranged to slide relative to and along the first arm and the second arm, wherein;

    the first and second supports are spaced across an opening, and the impact barrier is arranged between an open position and a closed position, such that in the closed position, the first and second arms are arranged in combination to traverse the opening; and

    when in the closed position, the coupling is arranged to slide along and relative to the first and second arms, by a distance of at least 25% of a length of one of the first arm and the second arm, from a first position in which the coupling is mounted on only the first arm to a second position in which the coupling is mounted on both the first and second arms; and

    a projection provided on the second arm, the projection arranged to abut the coupling to impede movement of the coupling along the second arm beyond the second position when the impact barrier is arranged in the closed position.
