24、 parts of ISO 7176. -,-,- ISO 7176-19:2008(E) vi ISO 2008 All rights reserved Introduction Transportation safety research has shown that the vehicle seat is an important part of the occupant-restraint system and therefore plays a key role in reducing the risk of serious injuries to vehicle occupants
25、 in many types of vehicle crashes. In particular, the seat needs to allow and facilitate the proper positioning of belt restraints on the skeletal regions of the occupant, not add to occupant loads during impact loading, and provide effective support for the occupant so that the belt restraint will
26、remain in place over skeletal regions throughout a crash. People with physical disabilities must often remain in their wheelchairs whilst travelling in motor vehicles as drivers or passengers. Since many wheelchairs were not designed for this purpose, wheelchair-seated occupants are often at higher
27、risk of injury in crashes than are people seated in seats provided by the vehicle manufacturer. ISO 10542-1 provides design, performance, labelling, and the manufacturers literature requirements, and specifies associated test methods, for wheelchair tiedown and occupant-restraint systems (WTORS). Th
28、is part of ISO 7176 addresses the seating part of wheelchair-user occupant-protection systems by establishing design, performance, labelling, and the manufacturers literature requirements, as well as associated test methods, for wheelchairs that may be used as seats in motor vehicles. Whilst wheelch
29、airs may be secured by various types of tiedown and securement systems that were available throughout the world at the time this part of ISO 7176 was developed, effective wheelchair securement in the real world requires compatibility of the wheelchair tiedown system available in the vehicle and the
30、method of securement provided on the wheelchair. At the time that this part of ISO 7176 was developed, the four-point strap-type tiedown was considered to be the most effective, common, and universally adaptable system for securing a wide range of wheelchair types and sizes. For these reasons, this
31、part of ISO 7176 requires that wheelchairs intended for use as seats in motor vehicles provide for securement using a four-point strap-type tiedown system by providing at least four designated securement points, with two in front and two in the back. However, this part of ISO 7176 also provides for
32、evaluating wheelchairs that are also designed for securement by other methods, such as docking-type securement systems. To evaluate the crashworthiness performance of a wheelchair, Annex A specifies procedures for dynamically testing a wheelchair loaded with an appropriate-size crash-test dummy usin
33、g a 48 km/h crash pulse with the wheelchair secured facing forward on the impact sled. This test is based on well-documented motor vehicle crash and injury statistics, which show that more than 50 % of all serious injuries to occupants of motor vehicles occur in frontal crashes, and that more than 9
34、5 % of frontal crashes result in a longitudinal change in vehicle speed of less than 48 km/h. Dynamic performance for forward-facing wheelchairs in rear and side impacts might be addressed in future International Standards. This part of ISO 7176 has also been developed with the recognition that the
35、use of a pelvic-belt restraint alone does not provide the wheelchair occupant with the same level of crash protection in a frontal impact as the use of both pelvic-belt and shoulder-belt restraints. Therefore, the provisions and test methods of this part of ISO 7176 are based on the use of both pelv
36、ic- and shoulder-belt-type restraints. Although the four-point strap-type tiedown system was considered to be the most common and universal method for effectively securing a wide range of wheelchairs at the time this part of ISO 7176 was developed, it is a method of wheelchair securement that requir
37、es the involvement of a second person and cannot be implemented by the wheelchair occupant. Accordingly, it is desirable to progress toward a securement method that can be implemented independently by the wheelchair-seated passenger who may travel in different public transportation and private vehic
38、les. As a step toward this goal, this part of ISO 7176 includes a normative annex (Annex F) that establishes universal docking interface geometry (UDIG) for securement points on wheelchairs when it is intended for the wheelchair to be secured by docking-type securement devices in public transportati
39、on and/or multiple private vehicles. Finally, this part of ISO 7176 can be viewed in the totality of daily wheelchair use and the range of standards to which all wheelchairs are expected to comply. Wheelchairs are designed primarily to serve as effective mobility devices and, in that respect, they m
40、ust first conform to the applicable requirements set forth in other ISO 7176-19:2008(E) ISO 2008 All rights reserved vii parts of the ISO 7176 series. Transportation is only one of many daily activities that introduce unique circumstances and requirements that wheelchairs and wheelchair occupants ma
41、y experience. Wheelchair products that comply with this part of ISO 7176 will have additional features that provide increased levels of occupant security and safety whilst their occupants are riding in motor vehicles. However, a wheelchairs failure to comply with this part of ISO 7176 cannot be used
42、 to limit access to, and availability of, motor vehicle transportation for wheelchair users. -,-,- INTERNATIONAL STANDARD ISO 7176-19:2008(E) ISO 2008 All rights reserved 1 Wheelchairs Part 19: Wheeled mobility devices for use as seats in motor vehicles 1 Scope This part of ISO 7176 applies to all m

It applies to complete wheelchairs, including a base frame and seating system, as well as to wheelchairs equipped wi
