Introduction

This part of GB/T 18029 ensures that the seat and wheel size information is provided by specifying a consistent, repeatable measurement method Comparable, while providing the relevant information required by the prescribing person.

The chair and wheels of the wheelchair tend to be deformable, with a certain profile or a soft structure, with almost no consistent reference point to make reliable measurements. In the past, because manufacturers use different measurement methods, making them unable to compare the results of the measurement.

In addition, sometimes the choice of measurement items is due to ease of measurement rather than depending on clinical use. For example, the seat depth of the sling seat passes through Often measured along the sling material, regardless of the gap between the back of the seat and the backrest. This gap is sometimes as wide as 5cm and a large degree of shadow the actual depth of the seat. In addition, adjustable parts can cause some problems. these adjustable parts affect each other, may produce a large number of potential Measurement data.

This part of GB/T 18029 first places a standard load block on the wheelchair seat. The two load blocks specify the adult and the corresponding size of the child. The structure of this load block can be flexibly changed flexibly and provides a reference point for ease of measurement. Due to measurement the position is described relative to the position of the load block, so the precise positioning of the load block is the basis for the repeatability of the measurement results. This part is right this is also specified in detail. Finally, in order to facilitate comparison of the data from different manufacturers' products, this section also contains a uniform format for the measurement results.

It is worth noting that wheelchair production is usually a series of models, including a basic model and a series of derivatives Product. The key is to choose which model series to commission.

1 Scope

This part of GB/T 18029 specifies the measurement method for wheelchair seats and wheel dimensions.

This section applies to wheelchairs with indoor and outdoor movement and no more than 120km/h for disabled persons with a mass of not more than 120kg Vehicles and delivery vehicles, including the following wheelchairs and vehicles classified by GB/T 16432.

Manual steering of the electric wheelchair 122124 Power steering electric wheelchair 122127 A power wheelchair 122121 operated by a caregiver Manual wheelchair 122103 manipulated by caregiver Hands rear wheel drive wheelchair 122106 Hands front wheel drive wheelchair 122109 Hands swing lever wheel drive car 122112 Unilateral drive powered wheelchair (single or single) 122115 Foot drive wheelchair 122118 this part does not apply to wheelchairs with a seat width of less than 212mm.

This part of GB/T 18029 does not specify the nominal size of wheelchair seats and wheels.

Note. For this part of the wheelchair outside the scope of this part of GB/T 18029 may be given the provisions of the location should be measured. Designed for quality much more than the reference load (See Appendix A) and wheelchair trucks (elastic wheels and elastic seats) with compressible components, due to the compressible parts can not be completely compressed, the measurement may not be able to get the correct seat size.
