Abstract
The shock absorber device for telescopic protection devices is formed of a plurality of tubular covering elements which slide inside one another in a defined direction, each tubular element having a scraper and a stop on the scraper, the shock absorber device including at least one shock absorber part, positioned and operating between the scraper and the stop of two adjacent tubular elements, and a second shock absorber part, positioned and operating between the stops of two adjacent tubular elements, each shock absorber part consisting of a portion which connects it to a slotted zone or seat on the bar or stop and at least one flexible arm which extends from the connecting portion in a plane parallel with the direction of extension, the flexible arm being separated from the bar or stop by a given distance and including a first section substantially parallel with the bar or stop and a second section connected to the first and extending away from the said first section at an oblique angle to the bar or stop.
