Full title and description

Technical systems and aids for disabled or handicapped persons — Wheelchair tiedown and occupant-restraint systems — Part 2: Four-point strap-type tiedown systems. This International Standard specifies design and performance requirements for four-point strap-type wheelchair tiedown systems used to secure wheelchairs and restrain occupants in road vehicles and other transport applications.

Abstract

ISO 10542-2:2001 defines the functional and configuration requirements for four-point, strap-type tiedown assemblies, including geometry, adjustment, securement-point engagement and translatable design guidance that complements the general requirements and test methods given in ISO 10542-1. The document was published in 2001 and is concerned with vehicle- and wheelchair-interface securement performance rather than vehicle structural design.

Scope

ISO 10542-2:2001 applies to four-point, strap-type tiedown systems intended to secure wheelchairs and restrain occupants in transport. It supplements the general requirements and test methods in ISO 10542-1 by specifying design constraints (angles, attachment geometry, adjustability and engagement with wheelchair securement points) so the tiedown assemblies are effective across a wide range of wheelchair types and sizes. The standard is focused on tiedown assembly design and user-attachment interfaces rather than vehicle structural anchorage design.

Key topics and requirements

• Design for effective attachment and tensioning across a wide range of wheelchair types and sizes, including strap length adjustment and anchor-point positioning.
• Specified securement-point engagement compatible with the surrogate wheelchair definitions referenced in ISO 10542-1.
• Required angles and geometry for four-point strap configurations to ensure occupant restraint performance.
• Complementary relationship to ISO 10542-1 (requirements and test methods) — this part adds specific provisions for strap-type tiedowns.
• Guidance on adjustability, end fittings and securement-point zones on wheelchairs to promote consistent performance.

Typical use and users

Used by vehicle designers, mobility-equipment manufacturers, system integrators and test laboratories concerned with wheelchair securement in road vehicles, buses, ambulances and other transport platforms. Regulatory bodies, procurement teams and accessibility specialists also reference the standard when specifying or assessing tiedown installations.

FAQ

Q: What is this standard?

A: ISO 10542-2:2001 is an International Standard that specified design requirements for four-point, strap-type wheelchair tiedown and occupant-restraint systems.

Q: What does it cover?

A: It covers the design, geometry, adjustability and securement-point engagement requirements for four-point strap tiedown assemblies and how they should interface with wheelchairs as referenced to the requirements/test methods in ISO 10542-1.

Q: Who typically uses it?

A: Mobility-equipment manufacturers, vehicle integrators, test laboratories, accessibility specialists and procurement or regulatory authorities involved with wheelchair securement in transport.

Q: Is it current or superseded?
