In one aspect of the invention, a vacuum anchor assembly (100, 100', 160) for anchoring a fall protection system (180, 181, 183, 184, 185) to a surface of an anchorage structure (178) comprises an anchor member (101, 108) having an air input connector (152, 153), a venturi (122), and a seal member (103, 110) incorporated into the anchor member (101, 108). The air input connector (152, 153) is configured and arranged to receive air from a pressurized air source (A). The venturi (122) is in fluid communication with the air input connector (152, 153) and is configured and arranged to receive air and create a vacuum therefrom. The seal member (103, 110) is in fluid communication with the venturi (122) and is configured and arranged to receive the vacuum and resulting suction and create a seal between the anchor member (101, 108) and the surface of the anchorage structure (178) sufficient to operatively connect the anchor member (101, 108) to the surface of the anchorage structure (178) with the vacuum and resulting suction created within the anchor member (101, 108).
Selon un aspect de l~invention, un ensemble d~ancrage par dépression (100, 100', 160) permettant d~ancrer un système anti-chute (180, 181, 183, 184, 185) sur une surface d~une structure d~ancrage (178) comprenant un élément d~ancrage (101, 108) comportant un raccord d~entrée d~air (152, 153), un venturi (122) et un élément d~étanchéité (103, 110) incorporé dans l~élément d~ancrage (101, 108). Le raccord d~entrée d~air (152, 153) est configuré et conçu pour recevoir de l~air provenant d~une source d~air sous pression (A). Le venturi (122) est en communication fluidique avec le raccord d~entrée d~air (152, 153) et est configuré et conçu pour recevoir l~air et créer une dépression. L~élément d~étanchéité (103, 110) est en communication fluidique avec le venturi (122) et est configuré et conçu pour recevoir la dépression et l~aspiration ainsi créée et réaliser un joint étanche suffisant entre l~élément d~ancrage (101, 108) et la surface de la structure d~ancrage (178) pour fixer l~élément d~ancrage (101, 108) sur la surface de la structure d~ancrage (178) grâce à la dépression et à l~aspiration ainsi créée au sein de l~élément d~ancrage (101, 108).
