Anti-extraction safety device for e.g. public transport vehicle, has rollers with fairing pieces whose base includes extensions extended under sides corresponding to rail so as to be opposed to any extraction force of guiding assembly

摘要

The device has guiding rollers (13, 14) including rotatably fixed fairing pieces (32, 33) whose base includes extensions (46, 47). The extensions are extended, under projecting sides (21, 22) corresponding to a guiding rail (19) so as to be opposed to any extraction force of a guiding assembly. The fairing pieces are mechanically twinned to form a monoblock fairing assembly and have a covering shape covering an outer face of the rollers and a part of its peripheral edge.
