A caravan door (1) is connected by restraint means to prevent it slamming in high winds. The restraint means offers only a small resistance to movement on low speeds of door movement and a high resistance on higher speeds. The restraint means comprises a pair of inertia belt reels (4, 5) attached to the wall of the caravan and whose belts (4b, 5b) are attached at their ends (6) to the door. <IMAGE> |
