Proposed Regulatory Change: Side-Impact Testing SafetyBeltSafe U.S.A. 49 CFR Part 571; Docket No. NHTSA RIN 2127-AK95 25 Comments submitted by April 28 on NPRM, backed by Congressional action in 2002 requiring action. NHTSA has reopened comment period till 10/2/14 due to JPMA letter, noting Q3 dummy unavailable for companies to pre-test. Covers research basis for proposal; dummy to be used; and proposed test architecture. Addresses proposed test approach submitted by Dorel Juvenile Group & Kettering University.
Proposed Regulatory Change: Side-Impact Testing SafetyBeltSafe U.S.A. Crash exposure for under age 12: : a.Frontal: 32%; side impact: 31%; rollovers: 25%; rear end: 11% b.More than half side impacts were “near-side”; all move toward point of impact. c.75% side-impact fatalities: under age 4 d.Substantial injury for safety seated: 43% frontal; 33% side (2/3rds of those from near side); 15% rollovers; 9% rear enders
Proposed Regulatory Change: Side-Impact Testing SafetyBeltSafe U.S.A. NHTSA data (1996) on safety seat effectiveness: Infants – 71% in cars, 59% in trucks; 1–4 year olds – 54% in cars, 59% in trucks Fatality data for frontal & side crashes for children from birth to age 3 (NHTSA, ) : 52% effectiveness in frontal crashes 42% effectiveness in side impacts (excluding crashes with rollovers)
Proposed Regulatory Change: Side-Impact Testing SafetyBeltSafe U.S.A. Assn. for Advancement of Automotive Medicine Report (Sherwood et al., 2003): Half of crashes unsurvivable. Of rest: 12% gross child seat misuse 16% side impacts 12% in frontals that might have been survivable. 40% of fatalities were in side impacts – the highest number. All included vehicle intrusion into the child’s seating position.
Characteristics of Crash Fatalities 0-12 years: % unrestrained. Of those with known restraint use, 38% in safety seats. Safety seat use varied: Under age 1: 76% 1 – 3 year olds: 65% 4 – 7 year olds: 28% 8 – 12 year olds: 2% Three-quarters of fatalities were children under age 4. Thus, NHTSA contends most effect from improved safety seats would reduce deaths of under 4 year olds
Vehicle Improvement FMVSS 214 Stronger vehicle requirements for side impact protection, including side air curtains. BUT youngest children ride too low for air curtain protection. NHTSA is building the regulation on the current vehicle structure & findings; quite diverse range for seat back angles, armrest protrusion into cabin.
Side-Impact Crash Test Proposal: The Takata Test Sled-test: forward-moving sled travelling at 15 mph, ‘T-boned’ at 30 mph. Child restraint placed on near-side of impact. Based on characteristics of testing for FMVSS 214 (tests of car side-impact protection). Modeled on typical side-impact crash (vehicle starting into intersection slowly hit by vehicle “running” into intersection); vehicle seat moves sideways so top of safety seat strikes intruding door.
Side-Impacts: Safety Seat Motion As collision occurs, lower part of safety seat moves toward far side, sending top of seat and child’s head toward intrusion.
Test Dummies NHTSA chose: a.CRABI (12 month old): measures containment rear facing b.Q3s (32-lb. 3 year old), used in Europe, to measure head injury and chest deflection. Measure head & thoracic forces to replicate real world. JPMA successfully petitioned for longer to submit comments (120 days more) due to paucity of Q3s dummies with which to test.
Findings on Current Safety Seats NHTSA proposal contains specific preliminary test data on current rear-facing-only, convertible, & combination seats. Test will allow head contact with door as analysis shows peak stress on head occurs prior to door strike from hitting seat “wings”. Rear-facing seats: must contain baby’s head. Forward-facing seats: chest deflection, head injury criteria will be assessed.
NHTSA ‘Predictions’ With 3 years of lead time to meet standard, manufacturers will be able to lengthen head wings or add more force-handling padding on current seats with little disruption. Boosters without backs will not pass; can be labeled for children 40 lbs.+ Boosters with backs may strengthen head area OR mandate use by those 40 lbs.+
Findings of ‘Fleet’ Rear-facing-only seats: of 12 seats, only Combi Shuttle allowed head contact with door. Forward-facing seats: at least 75% of head must be enclosed by wings if want to prevent injury. ‘Good design’: Britax Advocate & Dorel Air Protect ‘Average’: majority of seats ‘Poor design’: Evenflo Chase & Diono Radian 65.
How Big is the U.S. Safety Seat Market? 7.42 million child restraints sold annually. Cost for tests: less than $1 per seat.
How Will Seats Be Installed? Rear-facing seats: lower anchors only. Forward-facing seats: LATCH (lower anchors & tether).
What is Missing? Incorrect use, esp. without tether attached given that observational data suggest widespread lack of tethering: NHTSA: at least 30% non-use. IIHS: 57% non-use overall, 83% non-use in pickup trucks (sample size: 1500). Shoulder-lap belt/lap belt installation: NHTSA data indicate method of attachment (belt vs lower anchorages) shows no meaningful differences. Lap belts are no longer legal in back seat. Shoulder-lap belts tend to mimic tether use.
What is Missing? No testing with dummy over 40 lbs. No testing of belt-positioning boosters rated above 40 lbs. (Will likely affect marketing of boosters.)

Research: Booster Seat Effectiveness SafetyBeltSafe U.S.A. ‘Effectiveness of Booster Seats Compared With No Restraint or Seat Belt Alone for Crash Injury Prevention’, Ma et al. Academic Emergency Medicine (2013) Analysis of 514 children in crashes from National Automotive Sampling System. Findings: No overall decrease in injury through use of boosters over safety belts alone. Significant increase in risk of neck injury among booster users.
Research: Booster Seat Effectiveness SafetyBeltSafe U.S.A. Cautions: Many other studies have found increased effectiveness of boosters over belts alone. Research sample included: Children age 0 – 10. Children using lap-only belt with booster. Increase in injuries found in least severe category (minor abrasions, sprains etc.).
Research: Booster Seat Usage Rates SafetyBeltSafe U.S.A. Pickrell, T. M., & Choi, E-H. (2014, June). The 2013 national survey of the use of booster seats. (Report No. DOT HS ). Washington, DC: National Highway Traffic Safety Administration National probability sample in which adult with child is interviewed as well as child’s seat use observed Goal: to observe restraint use of children ages 4 to 7 in 2013 compared with Key finding: overall restraint use for under age 13 at 91% is similar to 2011; but significant changes found in details summarized below.
Research: Booster Seat Usage Rates SafetyBeltSafe U.S.A. Details of Findings: Clues for Outreach Focus Use of any kind of restraint declines with age: Birth to 12 months: 95%. By age 12: 89%. Significant changes: 1-3 year olds: rear facing 10% (7% 2011) 7% in boosters, a decrease of 5%; Restraint usage for white children (non-Latino) rose to 95% from 91% for ages For all ages 1 to 12 years, white and Asian children had much higher restraint usage than black and Latino children riding with adults ages But for Asian children 8-12, usage fell to 86% from 95% in Usage for black children, age 8-12, was only 69%.
Research: Booster Seat Usage Rates SafetyBeltSafe U.S.A. Details of Findings: Clues for Outreach Focus 2% increase in use of forward-facing seats with harnesses for 4- to-7 year olds to 20% 1% decrease in belt use instead of safety seat use for 4-to-7 year olds to 24%. Occupants in vehicles with children: for year olds, Latino at 93% usage was higher than white teens, 92%, & much higher than black teens, 75%. For main age group, 25-69, black adults at 81% usage were much lower than Latino, 88%, and other groups at 94%.
