- 8 - SUMMARY: With this equipment for the ventilation of the passenger space of rapidly moving lift cages (1), an air current generated during the travel due to the ram pressure of the lift cage (1) gets at low inflow speed into the passenger space of the lift cage (1). Several ventilation slots (14) of a ventilating equipment (13), which lie one above the other and open into the passenger space of the lift cage (1), are arranged in a ventilation channel (15) extending over the entire height of the lift cage (1). The total cross-section of the ventilation slots (14) is approximately twice as great as the cross-section of the ventilation channel (15). The ventilation slots (14) are formed by portions (18) punched out of a sheet metal carrier (16), on which additionally strips (21), which are cut to size, of a laminated material plate can be glued on at the passenger space side and on which a perforated metal re-inforcing plate (19) is spot-welded onto the rear side. The metal re-inforcing plate (19) displays perforations (20), which can be spaced from the sheet metal carrier (16) by bent-over edge portions (24) arranged in the longitudinal direction of the ventilation slots (4). The cross-section of the perforation (20) is at least equally great as the cross-section of the associated ventilation slot (14). (Figure 6)
