Safety equipment for passenger conveying plants, in particular for escalators and moving walkways with at least one comb plate which actuates a safety switch by way of trigger means in the case of a force action exceeding a settable amount in horizontal or in vertical direction. The comb plate is movable horizontally and vertically against the static force of a force F or against its components Fh and Fv. The static triggering force F is set by means of a biasable spring (5) and divided into the static triggering force components Fh and Fv by an adjustable angular position of the line of action of the spring (5). The ratio Fh:Fv is selectable by appropriate angular position of the line of action of the spring (5). The setting of the angular position is possible by simple manual resetting within a certain angular range without constructional action on the safety equipment. Detent notches (12) and detent pins (13) assure a constant maintenance of the set angle.
