21、IntroductionProviding safe transportation for wheelchair-seated passengers of motor vehicles usually requires installation of aftermarket equipment to secure the wheelchair and provide passenger restraint during emergency vehicle manoeuvres and crash conditions that are appropriate to the size and t

22、ravel conditions of the vehicle. ISO 10542-1 establishes design and performance requirements and associated test methods for wheelchair tiedown and occupant restraint systems (WTORS) intended for use by wheelchair-seated passengers in all types of motor vehicles that have been modified for use by pe

23、ople seated in wheelchairs. The provisions of ISO 10542-1 were based on the belief that WTORS manufacturers are not able to control the types of vehicles and travel modes in which most of their products are installed and used. ISO 10542-1 therefore requires frontal sled-impact testing of WTORS to no

24、minally worst-case crash conditions of smaller vehicles, such as full-size vans and minivans, using a simulated crash acceleration/deceleration pulse that results in a change in sled speed (delta V) of 48 km/h.While this one-size-fits-all approach to WTORS, crashworthiness testing is appropriate for

25、 equipment intended for general use in all types of motor vehicles, it generally leads to products that are over designed for larger and heavier vehicles used primarily in low-speed intra-city transportation. This is particularly the case for accessible transit vehicles in which passengers are allow

26、ed to travel standing as well as sitting, hereafter referred to as accessible transit vehicles for standing and sitting passengers (ATV-SS).Recognizing these different and significantly lower transportation safety requirements for ATV-SSs in a new standard can be expected to result in alternative so

27、lutions for safely transporting wheelchair-seated passengers in these vehicle environments that are more compatible with the operational needs (e.g. fixed-route schedules) of these transportation services, and that offer wheelchair users a greater level of usability and independence than is achieved

28、 with WTORS designed to comply with 48 km/h crash conditions. More specifically, accident/injury data for ATV-SSs indicate that the frequencies of occupant fatalities and serious injuries per million passenger kilometres travelled are significantly lower than for smaller vehicles that travel at much

29、 higher speeds.1In fact, analysis of data from police reports of accidents involving fixed-route intra-city buses indicates that the likelihood of a collision event for these vehicles is sufficiently rare to justify basing performance requirements for safety equipment installed in these vehicles on

30、accelerations and decelerations that occur during non-crash conditions, such as emergency vehicle manoeuvres, including sudden stopping, sudden acceleration, and turning. Three studies have clearly demonstrated that ATV-SS accelerations that may result from such emergency manoeuvres are all below 1

31、g.234In-vehicle wheelchair user studies and user surveys have shown that commonly installed 4-point tiedown systems cannot be used independently by wheelchair-seated passengers, and vehicle operators are therefore responsible to secure wheelchairs using a 4-point, strap-type tiedown.567Due to the in

32、creasingly independent nature of public vehicles in combination with the length of time it takes to properly apply 4-point tiedown systems to wheelchairs, bus operators and wheelchair users often forfeit the use of strap-type tiedowns or bus operators fail to properly use all four tiedown straps. Un

33、secured wheelchairs in ATV-SSs have been demonstrated to slide or tip forward during vehicle stops, and wheelchairs rotated into the aisle and scooters tipped sideways during vehicle turns.4Additionally, there is anecdotal evidence of wheelchair passengers coming out of their wheelchairs and sustain

34、ing serious-to-fatal injuries during normal or sudden vehicle stops and turns due to non-use or improper use of belt restraint systems.ISO 10542-1 provides design and performance criteria for docking-type tiedown systems which can be independently used by wheelchair users and reduce securement non-u

35、se. During in-vehicle observations, wheelchair users have expressed a preference for using a forward-facing automated docking securement system due to its independent and comfortable use, forward-facing travel direction and eliminated need for vehicle operator assistance.8However, wide-spread adopti

36、on of docking systems for use in ATV-SS cannot occur without the implementation of standardized universal docking interface geometry (described in ISO 10542-1 and ISO 7176-19 as a normative annex) for wheelchair securement on all wheelchairs, which is a long-term goal.Over the past decade, rear-faci

37、ng wheelchair passenger spaces (RF-WPS) have emerged in ATV-SSs because they allow independence and ease of use by wheelchair-seated passengers. ISO 10865-1 ISO 2015 All rights reserved vBS ISO 10865-2:2015ISO 10865-2:2015(E)includes design requirements and performance criteria for RF-WPS. However,

38、in-vehicle studies have shown that rear-facing travel is, for some people, less comfortable than forward-facing travel due to vertigo8and unexpected upper-body and head movements during vehicle stopping and starting.3Rear-facing travel also doesnt allow passengers to see stops down the road.Thus, al

39、though RF-WPS may be a safer and more independent solution for wheelchair-seated travellers, forward facing can be the preferred orientation for passengers in ATV-SSs. Also, in the US, the Americans with Disabilities Act (ADA) currently allows rear-facing wheelchair transport but mandates at least o

40、ne forward-facing WPS in ATV-SSs. Therefore, rear-facing systems only serve part of the wheelchair-seated passenger population who seek safer transportation when using ATV-SSs.The purpose of this part of ISO 10865 is to establish minimum design requirements and performance criteria for forward-facin

41、g wheelchair passenger spaces (FF-WPSs) in ATV-SSs. This part of ISO 10865 also establishes test methods for the performance criteria, so that the passenger sitting in wheelchairs using a FF-WPS are provided a reasonable level of safety during transportation while maintaining a high level of usabili

42、ty and independence during travel in ATV-SSs. Since wheelchair and passenger act as independent systems under different types of vehicle accelerations (braking, accelerating and turning), a dynamic (non-static) test is required and described in Annex A. Furthermore, since manufacturers may design a

43、close-fitting means of occupant retention to retain a wheelchair passenger, the dynamic test method of Annex A requires the use of a test dummy that represents the anthropometrics of an average passenger seated in a wheelchair. A fundamental principle behind the concept of a FF-WPS in ATV-SSs is tha

44、t successful “containment” of an occupied wheelchair during normal travel and emergency vehicle manoeuvres is sufficient to provide a reasonable level of safety, that is, a level of safety comparable to that provided to other vehicle occupants, including standing passengers, who hold onto bars and s

45、traps to limit movement during non-crash vehicle accelerations and decelerations.The primary feature of a FF-WPS required by this part of ISO 10865 is a means to prevent forward movement of wheelchairs and their occupants during vehicle decelerations that occur in normal or emergency braking. Latera

46、l movement, rotation, and tipping of occupied wheelchairs in a FF-WPS are typically limited in one direction by the vehicle sidewall. Lateral movement, rotation, or tipping of the wheelchair into the centre aisle can be limited by a physical barrier, such as a vertical bar, horizontal bar or padded

47、stanchion. During motor vehicle acceleration, wheelchair movement toward the rear of the motor vehicle can occur. This movement is limited, in part, by friction of the vehicle floor within the FF-WPS that will generate resistance forces on the tyres of wheels that have been locked by applying the wh

48、eelchair brakes or by the drive train of powered wheelchairs for which the power has been turned off during travel. Due to insufficient resistance to rearward movement from manual brakes, FF-WPS must also provide other means for limiting rearward wheelchair movement. For example, rearward wheelchair

49、 movement can be limited by vehicle-anchored wheelchair containment devices, such as a bar or raised padded area behind the wheelchair), a wheel “capturing” device, or a hook-type device that is within easy reach and that can be secured to the wheelchair by most wheelchair passengers.Belt type occupant restraints have been provided in ATV-SSs to reduce the risk of injury among wheelchair passengers during travel. However, studies indicate that these belt-type occupant restraints are rarely used or are used improperly in ATV-SSs.579
