10、r bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmenta
11、l and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.International Standards are drafted in accordance with the rules given in the ISO/IEC Directiv
12、es, Part 2.The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies c
13、asting a vote.Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights.ISO 16121-1 was prepared by Technical Committee ISO/TC 22, Road vehicles, Subcommittee S
14、C 13, Ergonomics applicable to road vehicles.This second edition cancels and replaces the first edition (ISO 16121-1:2005), which has been technically revised.ISO 16121 consists of the following parts under the general title Road vehicles Ergonomic requirements for the drivers workplace in line-serv

16、uled urban and interurban services increase the already high physical and mental strains on the drivers.It is the aim of this part of ISO 16121 to supply the designer of line-service buses with information about how to develop an overall ergonomic concept for the drivers workplace. The recommended r
17、equirements on the drivers workplace for line-service buses made in this part of ISO 16121 are based on the scientific conclusions of the research project “Drivers workplace in the line-service bus”. This was conducted in Germany and summarized in the VDV 234 3recommendation. Further comprehensive e
18、rgonomic studies related to the design of an enhanced driver workplace conducted in the United States, Canada, the Netherlands, Sweden and the United Kingdom 4, 5, 6, 7, 8have been considered and found to provide recommendations covering similar areas.This part of ISO 16121 sets out to consider the
19、practical implications for all ranges of drivers, but particularly those with statures from 1,55 m (small female) to 2,0 m (large male). These statures include shoes (30 mm).It is also essential that the designer refers to the specifications and requirements of all parts of ISO 16121 (Parts 1 to 4)
20、before completing the design of a drivers workplace.It should be noted that where there is also national legislation covering any of the subjects contained herein, then both should be complied with. However, if a contradiction between the two should arise in any specific area, then the legislation s
21、hould prevail for that specific point only. Other technical solutions, at least equal with regard to ergonomics, should not be excluded.

22、neral description, basic requirements1 ScopeThis part of ISO 16121 applies to the drivers workplace in low-floor line-service buses designed for the carriage of passengers, comprising more than eight seats in addition to the drivers seat, and having a maximum weight exceeding five metric tonnes and
23、an overall width exceeding 2,30 m.This part of ISO 16121 contains basic requirements for an ergonomic and comfortable seating position, which is essential to keep drivers in a good state of health. The dimensions and mounting positions of a drivers seat, pedals and steering should be carefully chose
24、n to enable drivers to sit in an ergonomic seating position, i.e. sitting at angles which comply with the given ranges of comfort and to allow some variation when seated.2 Normative referencesThe following referenced documents are indispensable for the application of this document.

32、he reference system is formed by the zero-X-plane, zero-Y-plane and zero-Z-plane, which are perpendicular to each other.The intersection point (coordinate origin) of all three planes corresponds to the AHP projected onto the zero-Y-plane. The intersection line of the zero-X-plane with the zero-Z-pla
33、ne is referred to as the AHP Line.The X, Y and Z axes are oriented so that the negative coordinate range lies in front of the zero-X-plane, on the left of the zero-Y-plane and below the zero-Z-plane, when one is looking in the direction of driving forward.2 ISO 2012 All rights reservedBS ISO 16121-1

This tolerance, however, is not applicable when dimensions are specified as a
35、 range of values (e.g. x = 10 mm to 30 mm).4.1.3 AHPThe AHP is defined for three basic types of throttle pedal design as follows: For treadle (organ) type pedals (see Figure 2a), the AHP is the intersection of the depressed floor or other heel support with a line projected from the upper surface of
36、the throttle pedal. For hanging (pendulum) type pedals (see Figure 2b), the AHP is the point which intersects with the depressed floor or other heel support when an arc 200 mm in length is taken from the centre of the pedal surface. For treadle (organ) type pedals with a fixed heel stop (see Figure
37、2c), the AHP shall be taken as the intersection between the heel stop and the pedal surface.In all cases, the AHP shall lie on the vertical centreline of the pedal.

39、side dimension) shall be such that the driver can attain the full range of adjustment (see Table 1), including swivel (where such a mechanism is fitted) without restriction. The depth of the footwell shall be at least 350 mm (see Figure 3) forward of AHP.4.2.1.2 Drivers workplace widthThe width of t
40、he drivers workplace shall be chosen in such a way that sufficient distance to all interior surfaces to either side of the driver (laterally from head to foot) and sufficient leg freedom are available, including space for seat swivel. For the protection of the fingers a clearance distance of 25 mm f
41、rom the outer extremities of the seat shall be kept.The minimum lateral elbow room (ymin) in the shoulder range shall be 800 mm for all seat positions during driving.4.2.2 Access to the drivers workplaceIn low-floor buses, the drivers workplace should be arranged on a platform. It is recommended tha
42、t this platform be at a height of 300 50 mm above the floor and be reached by a single step. If the platform height is greater than 350 mm, steps with equal height shall be provided with a maximum height of 250 mm and a minimum height of 125 mm.Clear and unrestricted access to the drivers workplace
43、shall be ensured, with a passage width of at least 500 mm.These requirements are for normal entrance to the drivers workplace and do not necessarily apply to additional emergency exit doors.4.2.3 Stowage spaceIn the drivers workplace, a space for the drivers bag should be provided, e.g. in the cabin
44、 door. The stowage dimensions (length height width) for the drivers bag should be at least 480 mm 330 mm 170 mm (240 mm preferred, where possible).It should be possible to open the bag for the withdrawal of objects in the compartment. For personal objects needed during the drive (e.g. sunglasses) ad
45、ditional, easy-to-reach, non-slip stowage space should be available.A coat hook should be provided inside the drivers cabin. A coat hung on the coat hook shall not interfere with the operation of controls nor obstruct the drivers view. Optionally, a hanger may be provided.A lockable compartment for
46、valuables shall be available.4.2.4 WallA wall should be provided behind the driver.
