The United States will not support the proposed amendment in its current form. The amendment would increase headrest heights for front outboard seating positions from 800 mm to at least 830 mm while allowing a decrease in minimum heights to 720 mm from 750mm. In addition, the amendment would allow decreased rear heights. The US believes the amendment lacks adequate evidence-based justifications for the proposed changes.

The expert group on the 2nd phase development of GTR No. 7 has proposed a new method for measuring head-restraint height and, using this method, proposed to specify heights between 720-830 mm. OICA accepts the new measurement method, but argues for keeping the current 800 mm specification on the grounds that 800 mm under the new method would be 830 mm under the old.
