— for a vehicle, with designated priority seats, with multiple external doors the priority seats shall be within the first 15% of fixed seats, in each possible direction from each external door (only where there are more than eight seats fitted);
— in addition to the requirements above, where there Is an area with another class of seating within a vehicle (for example 1st class) the proportionate number of priority seats for that class shall be within the first 30 % of the fixed seats arrived at when entering that area (if entry to the area is possible from multiple directions then 15 % from each direction);
— in double deck vehicles, units or trainsets, priority seats can be present on any deck.
NOTE 2 Passage to priority seats should involve as little height change as possible, preferably on the same level as the entrance.
4) The level of equipment fitted to the priority seat shall, as a minimum, be the same as that fitted to the general seats of the same type.
— “Types in this context is understood as, for example, first class or second class seat, in a row or face to face.
— When, for example, second class seats in a row are fitted with a tray and a magazine holder, then second class priority seats in a row shall also be fitted with a tray and a magazine holder.
5) When seats are fitted with armrests, priority seats of the same type:
— shall be fitted with movable armrests:
— “Type’ in this context is understood as, for example, first class or second class seat. in a row or face to face
— This excludes armrests placed along the vehicle bodyside or along a partition wall in the case of compartments.
— The required force to move an armrest out of the way should be less than 60 N but it is recommended that it should be approximately 25 N.
— The movable armrest shall move into a position in line with the seat back cushion to enable unrestricted access to the seat or to any adjacent priority seats.
— Cross sectional views (longitudinal for transverse seating and transverse for longitudinal seating) shall be taken through the centre line of the seal
— When reclining seats are fitted, the dimensions shall be measured when the seat is in its fully upright position.
NOTE 3 Consideration should be given to provide adequate space under or adjacent to, at least one of the priority seats for a guide dog in each vehicle where priority seats are provided.
8) The whole usable sitting surface of the priority seat shall be a minimLim of 450 mm wide (see Annex A).
— In the case of a seat fitted with armrests the assessed width shall be between the armrests of the seat and shall be a minimum of 450 mm.
— It a reclining control is located in the armrest, the protrusion of such control shall not be taken into account for seat width measurement.
— Where a seat is not fitted with an armrest the assessed width shall be measured between lateral edges of the seat cushion with the cushion in its uncompressed state.
— If a single cushion provides more than one seat, then each seat is considered to have an
equal proportion of the space between the lateral edges of the total cushion (e.g. on a
850 mm wide cushion for two persons, it is not permissible to state that one seat has a
nominal 450 mm width so that it can be designated as a priority seat).
9) The top of each priority seat cushion shall be between 430 mm and 500 mm above floor level at the front edge of the seat.
— Shall be measured from the Iloor covering level to the top surface of the cushion.
— Measurement shall be taken through the centre line of the seat (longitudinal), with the cushion in its uncompressed state.
10) The clear headroom above each seat shall be at least 1 680 mm from floor level (see Annex A).
— On double-decker trains where luggage racks are provided above the seats a reduced headroom of 1 520 mm is permitted for priority seats underneath the luggage racks. provided that at least 50 % of priority seats maintain a headroom of 1 680 mm.BS/EN 16585-2-2017 pdf download.
