CSA Z605 – Mobility Aid Securement and Occupant Restraint Systems
CSA Z605 addresses mobility aid securement and occupant restraint systems for motor vehicles in the Canadian standards context. The terminology often uses MASOR – mobility aid securement and occupant restraint – rather than WTORS.
What does CSA Z605 address?
The standard covers the securement of the mobility aid and the restraint of the occupant as related but separate safety functions, together with system design, performance, testing and product information requirements.
How does MASOR relate to WTORS?
The terminology differs, but the underlying safety problem is similar: the mobility aid or wheelchair must be secured to the vehicle, and the occupant must be appropriately restrained.
Is CSA Z605 the only requirement for a Canadian vehicle?
No single standards summary should be treated as the complete regulatory answer. Vehicle requirements, equipment requirements, provincial rules, manufacturer instructions and other referenced standards may also apply.
How does Estraints support Canadian applications?
Estraints includes a Canadian standards pathway for restraint geometry calculations and documentation. Users remain responsible for selecting the correct current standard and satisfying all vehicle and regulatory requirements.
