2.5.6 Rear wheels<br />
The rear wheel should be in a position that allows the user to have the best push stroke as possible<br />
and keeps the user safely balanced according to his or her skill level and ability. The position of the<br />
rear wheel should allow the user to have a good push stroke and provide the necessary stability.<br />
2.5.7 Evaluating seating and postural support elements<br />
It is recommended that wheelchairs and cushions be evaluated based on the seating and postural<br />
support performance measures, and the results be available to the users and purchasers. The areas<br />
in which a wheelchair and cushion should be evaluated or reported on are:<br />
• seating dimensions and adjustability<br />
• cushion type and characteristics.<br />
Seating dimensions and cushion characteristics tests and reporting techniques are covered in ISO<br />
standards 7176-7 and 16840-2 (5).<br />
2.6 Strength, durability and safety<br />
The goal of this section is to help define what makes a safe and reliable wheelchair, and how to<br />
evaluate and report these attributes to stakeholders (see Box 2.8). When a wheelchair fails, the user<br />
is not only at risk of injury but may not be able to go anywhere or do anything until the wheelchair<br />
is repaired or replaced.<br />
Apart from ensuring that the wheelchair is safe and effective, evaluating strength and durability is<br />
a way of gathering important information that can be useful for all stakeholders – users, designers,<br />
providers, manufacturers and funding agencies. Keeping accurate records of the results of strength<br />
and durability tests will help wheelchair designs evolve so that their quality and effectiveness<br />
continually improve.<br />
Box 2.8. Strength, durability and safety guidelines<br />
n All wheelchairs should meet the strength, durability and safety requirements of user(s) in their own environment(s).<br />
n It is recommended that each country develop its own wheelchair standards to ensure a reasonable quality, for<br />
instance by using the ISO 7176 series of standards as a basis. When developing national standards, it is important<br />
to consider the weights and sizes of the users, typical use, available testing equipment and available wheelchair<br />
technology. The standards should be available to manufacturers, purchasers and users, and be reviewed from time to<br />
time.<br />
n All wheelchairs should be evaluated based on the strength, durability and safety requirements set by the country, and<br />
the results should be available to users and purchasers.
