An unrollable safety system has a box (15) accommodating a net (11) which contains a device with a rotatable shaft on which the net (11) can be rolled up and out. One or more supports (12, 25) can be positioned specific distances away from the box (15). Moreover, at least one longitudinal element (16), preferably a rope, that can be pulled out of the box (15) and can be held by the positioned supports (12, 25) is provided on which the net (11) is rolled out and held like a curtain by means of brackets (21). The net (11), as meshwork, is flexible, and so designed to be able to roll up, it being produced from a plurality of wires, ropes and/or cords bent in coil shapes. The wires (13), ropes and/or cords bend in coil shapes are preferably aligned perpendicularly to the direction of pulling out the net (11) so that the net can be rolled up on the shaft. A mobile or stationary barrier over shorter or longer distances, with a high degree of stability and with simple and rapid assembly and dismantling has thus been produced. |
