Vehicle security method and device

Abstract

A method of providing security for an interior region of a vehicle (12) having an opening bounded by frame through which opening access can be had to the interior region from outside the vehicle, the frame being provided with a closure mechanism such as a door, the closure mechanism being displaceable relative to the frame between a closed position, when the opening is closed by way of the closure member (13) and an open position wherein the closure member allows access through the opening to the interior region; the closure member containing a window (19) characterized by the steps of locating from within the interior region over the window in the closure member a blocking device; the blocking device being adapted, in a working position, for demountable coupling of the blocking device to the closure member; providing on the blocking device a displaceable extension (25′, 26′) such that, with the closure mechanism in the closed position and the blocking mechanism in its working position, the extension (25′, 26′, B, B′) can be moved between a locking position wherein the extension interacts with the frame or an extension thereof so as to resist movement of the closure member from the closed position towards the open position; and a release position wherein the extension no longer interacts with the frame or an extension thereof so as to enable the closure member to move from the closed position towards the open position.
