The problem of head restraints (HRs) interfering with CR installation seems to be growing because HR design improvements for non-CR passengers can actually be at odds with CR installation ease. Injury reduction is more effective when the HR is closer to the back of the head, so the trend is for HR designs to protrude further into the seating area – sometimes preventing the back of a forward-facing CR from being aligned with the seatback. Unfortunately, this mismatch coincides with an increased use of high-weight harness (HWH) seats and higher-backed boosters, which are taller and much more likely to reach the height of the HR.
