Abstract
A safety device is provided for transport systems such as walkways and stairs that include moving elements () with longitudinal movements and in which one of the moving elements () may undergo tilting movements in relation to an operating direction. A safety counter-guide () is arranged on the moving elements () and prevents the upward tilting of the moving elements (). The safety counter-guide also includes a lower sensor () in the form of a band that generates a stop signal for the system upon coming into contact with moving elements (). Since the moving elements () cannot tilt in an upwards direction, possible risks both for the user and for the mechanical system are prevented.
