The safety slide comprises a lower fixed profile and an upper mobile profile. The lower fixed profile is of a U-shaped section and is formed with vertical wings horizontally bent for forming a lower rolling path and an upper guiding path in order to cooperate with balls. Rollers are placed between the vertical wings of the lower fixed profile and bent wings formed on the upper mobile profile with stiffening longitudinal corrugations, and are guided by vertical wings of the mobile upper profile. |
