UN ECE R25 — Head Restraints · 04 / S2

Meet at least the 04-series requirements for a new R25 application. Use 04 series · Supplement 2 for the current application.

• Head restraints for folding, side-facing or rearward-facing seats are excluded.
• Head restraints complying with R17 do not also need to meet R25. R80-approved M3 seats and R80-approved seats of M2 vehicles exceeding 3,500 kg maximum mass are also exempt.

Identify the approval route for your head restraint and seat. If using R25, apply to the current level.

The latest level is 04 series · Supplement 2, effective from 12 June 2025. It does not impose a new expiry date on every approval.

• Supplement 2 updates the country-code reference and the reference for determining the seating position.
• It does not reset the height, strength or impact-test requirements for head restraints.

Use the current measurement-procedure reference in a new application.

Supplement 2 alone does not require you to redesign an existing head restraint. Validity of an existing approval depends on compliance with the 04-series requirements.

• The transition rules retain an exception for vehicle types complying with the 04 series; an old series number alone does not establish this.
• Notify the approving authority of changes to the head-restraint type; it may require a further test report.

Check the certificate and evidence of 04-series compliance. Notify product changes to the approval authority.
