<p>The shock absorber device for telescopic protection devices is formed of a plurality of tubular covering elements (2) which slide inside one another in a direction (F), each tubular element (2) having a scraper (5) and a stop (2d) on the scraper (5), the shock absorber device including at least one shock absorber part (6), positioned and operating between the scraper (5) and the stop (2d) of two adjacent tubular elements (2), and a second shock absorber part (13), positioned and operating between the stops (2d) of two adjacent tubular elements (2), each shock absorber part (6, 13) consisting of a portion (7) which connects it to a slotted zone or seat (4a, 2e) on the bar (4) or stop (2d) and at least one flexible arm (8) which extends from the connecting portion (7) in a plane parallel with the direction of extension (F), the flexible arm (8) being separated from the bar (4) or stop (2d) by a given distance (d) and including a first section (8a) substantially parallel with the bar (4) or stop (2d) and a second section (8c) connected to the first and extending away from the said first section (8a) at an oblique angle to the bar (4) or stop (2d). <IMAGE></p> |
