Terminology and conventions. The text of the international standard has been approved as suitable for publication as a British Standard without deviation. Some terminology and certain conventions are not identical with those used in British Standards; attention is drawn especially to the following. Wherever the words “International Standard” appear, referring to this standard, they should be read as “British Standard”. The Technical Committee has reviewed the provisions of ISO 7176/7 and ISO 7193, to which reference has been made in clause 2 and 3.5, and has decided that they are acceptable for use in conjunction with this standard. A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations.

This combination comprises a propulsion system, a steering system and a braking system (push handles and tipping levers are also included). 3.2.1 propulsion system Combination of the parts of the wheelchair that are needed for propulsion. This combination comprises a control gear, a transmission and driving wheels. 3.2.1.1 propulsion control gear2) the part of the propulsion system that is directly actuated by the driver in order to provide the transmission with the power needed for propulsion.

The wheelbrake can be: a friction brake, where the force is developed by friction between parts of the wheelchair that are movable in relation to each other; the friction force may be generated by mechanical, hydraulic or electrical means, or by any combination of these; an electric brake, where the force is created by electromagnetic action on parts of the wheelchair that are movable in relation to each other but not in contact with each other. 3.2.3.3.1 service brake the braking system that the driver normally uses to reduce the speed of the wheelchair or stop it completely 3.2.3.3.2 parking brake the braking system that is intended for keeping the wheelchair stationary on sloping ground whether or not the wheelchair is occupied 3.3 Wheels 3.3.1 driving wheel a wheel that is connected to the driving system and when in contact with the underlay develops the propelling force 3.3.2 steering wheel a wheel that is connected to the steering system and when in contact with the underlay governs the driving direction 3.3.3 castor wheel a wheel that can pivot but is not intended to govern the driving direction 3.3.4 supporting wheel a wheel that cannot pivot and which is not intended to develop propelling forces or govern the driving direction 3.4 frame the frame unites and supports the other parts of the wheelchair. Seat-frame-backrest etc. could form, or be combined into, one unit or consist of separate parts 3.5 dimensions Dimensions commonly used to define a wheelchair include seat width, seat height, seat depth, backrest height, armrest height, width between armrests, overall width, overall height, overall length, overall width folded, overall height folded. These dimensions are illustrated as follows: 3.5.1 seat width3) (at seat level) 3.5.2 seat height3) (from floor) 3) For the determination of seating dimensions, see ISO 7176/7.
