Abstract

L'invention concerne un système de sécurité déroulable présentant une boîte (15) qui loge un filet (11) et contient un dispositif doté d'un arbre rotatif sur lequel le filet (11) peut enroulé ou duquel le filet peut être déroulé. Un ou plusieurs supports (12, 25) peuvent être posés à intervalles déterminés à une certaine distance de la boîte (15). En outre, au moins un élément longitudinal (16), de préférence un câble, qui peut être tiré de la boîte (15) et retenu lorsque les supports (12, 25) sont installés, est utilisé pour dérouler et retenir à la manière d'un rideau le filet (11) par le biais de brides (21). Le filet (11) est réalisé sous forme de treillis articulé et donc pouvant être enroulé sur lui-même, et il est fabriqué à partir d'une pluralité de fils, câbles et/ou torons spiralés. Les fils (13), câbles et/ou torons spiralés sont de préférence orientés perpendiculairement à la direction de traction du filet (11), afin que le filet puisse être enroulé sur l'arbre. Ainsi, on obtient une barrière mobile ou stationnaire de grande stabilité sur des distances relativement courtes ou longues et facile et rapide à monter et démonter.
