DIN 75078-2 2023-01 PDF

Full title and description

DIN 75078-2:2023-01 — Motor vehicle for the transport of persons with reduced mobility — Terms, requirements, testing — Part 2: Restraint systems (Rückhaltesysteme). This part specifies requirements, test methods and marking for occupant and wheelchair restraint systems used in motor vehicles designed to carry persons with reduced mobility; the published document includes additional digital content (CD-ROM).

Abstract

Part 2 of the DIN 75078 series addresses restraint systems (occupant and wheelchair restraint systems) for motor vehicles constructed or adapted to transport people with reduced mobility (KMP). It defines terms, performance and installation requirements, test procedures and graphical marking to reduce misuse of wheelchair securement and occupant‑restraint solutions. The work was prepared within the DIN committee for rescue service and hospitals (NARK) and replaces the earlier 2021 version.

Scope

This part applies to restraint systems used in motor vehicles for the transport of persons with reduced mobility (KMP). It covers requirements for vehicle anchorages and fittings, occupant and wheelchair restraint systems (including WTORS-type systems), testing procedures to verify performance, compatibility criteria between wheelchairs and restraint systems, and labelling/graphical markings intended to prevent incorrect use. The document is aimed at manufacturers, vehicle converters, testing bodies and operators of KMP.

Key topics and requirements

• Definitions and terminology specific to KMP and restraint systems.
• Performance requirements for occupant restraint systems and wheelchair tiedown systems (design loads, attachment integrity, adjustment ranges and belt angles).
• Requirements for vehicle anchorages, securement points and installation interfaces (compatibility with wheelchair securement arrangements).
• Test methods and procedures for frontal impact and fastening strength to validate restraint performance.
• Labelling, user instructions and graphical markings to reduce misuse and to indicate compatible wheelchair/securement combinations.
• Documentation and information required from manufacturers and installers (instructions for use, maintenance and inspection intervals).

Typical use and users

Used by vehicle converters and coachbuilders adapting vehicles for passengers with reduced mobility, manufacturers of restraint systems and wheelchairs, test laboratories performing compliance verification, procurement bodies and operators of transport services for persons with reduced mobility, and regulatory or certification bodies involved in vehicle safety and accessibility.

Related standards

Relevant documents and series typically referenced alongside DIN 75078-2 include DIN 75078-1 (Part 1: vehicle characteristics and equipment), ISO 10542 (wheelchair tiedown and occupant‑restraint systems), and the ISO 7176 series (wheelchair requirements, notably ISO 7176-19 for wheelchairs intended for use as seats in motor vehicles). These international standards address complementary requirements for wheelchair design, securement point design and test methods used in vehicle transport.

FAQ

Q: What is this standard?

A: DIN 75078-2:2023-01 is the DIN national standard that specifies terms, requirements and tests for restraint systems used in motor vehicles that transport persons with reduced mobility (part of the DIN 75078 series).

Q: What does it cover?

A: It covers requirements for occupant and wheelchair restraint systems, vehicle anchorages, test procedures, compatibility criteria and labelling/graphical marking to reduce incorrect use during transport of wheelchair users.

Q: Who typically uses it?

A: Vehicle converters, restraint‑system and wheelchair manufacturers, test laboratories, transport operators for persons with reduced mobility, procurement authorities and certification bodies.

Q: Is it current or superseded?

A: Current (published January 2023). It replaces the previous 2021-03 edition of DIN 75078-2. Users should verify they hold the 2023 edition for up-to-date requirements.

Q: Is it part of a series?

A: Yes — it is Part 2 of the DIN 75078 series addressing motor vehicles for the transport of persons with reduced mobility; Part 1 covers vehicle characteristics and equipment (DIN 75078-1). It is also related to international standards in the ISO 7176 and ISO 10542 series.
