发明名称 Barrier system
摘要 A barrier system of the type comprising posts or pillars from which webbing extends, commonly used to demark one area from another. The barrier system comprises a pillar that tapers from a larger area base to a smaller area top. A reel assembly is located at or proximate the base section and provides a deployable and retractable length of webbing that exits from the housing near the top. The plane of the webbing as it extends upwardly has its longitudinal direction extending generally upwardly and a guide, such as a conically tapered pulley, directs the webbing from a substantially vertically extending longitudinal configuration to a substantially horizontally extending configuration in which the webbing exits the housing.
