Fall protection device

A fall protection device for coupling a user who performs works on horizontal surfaces in construction sites to a fixed element of the construction, wherein the fall protection device is able to adopt two end positions, the first being an operating protection position and the second being a non-operating storage position, the fall protection device comprising:

• a mast intended to be arranged vertically in the operating protection position, having an upper portion and a lower portion, wherein the lower portion of the mast is releasably couplable to a fixed element of the construction with the possibility of pivoting on its own vertical axis;
• an arm intended to be arranged horizontally in the operating protection position forming an inverted L with the mast, being provided at a first end with an articulated joint that is articulated with the end of the upper portion of the mast, the second end thereof being a free end and the arm being configured to receive in an area of the second end the coupling of fastening and attachment means for the user;
• a shock-absorbing strut to cushion the pivotal movement of the arm towards the mast caused by a downward traction force occasionally applied at an area of the end of the arm by the fastening and attachment means for the user, the strut being provided with a first end joined articulately to the arm and a second end intended to be fastened, in the operating protection position, on a point of the upper portion of the mast under the end of the upper portion where the mast is articulated with the arm,
• characterised in that the articulation of the first end of the strut with the arm is a sliding articulation that can slide along the arm.
