  2. Extending 5-point Harnessing:Forward Facing Seat Options for Heavier Children • Caroline Langrall, CCLS, CPST • Mt. Washington Pediatric Hospital

  3. Outline • Challenges • Crash Dynamics • Seat Options • Special Needs

  4. Challenges • Lack of research • Historically, majority of affordable seats offered FFing harnessing to 40lbs. • Rise in Obesity • 3+y/o male,90th percentile for weight= 40lbs. (CDC, 2000) • Maturity for booster use.

  5. Challenges • Child must be mature enough to sit in a booster • 40lb, 4 year old • Dislodged belt from belt guide.

  6. Challenges • 4 year old. 42 lbs • Low back booster

  7. Challenges • 3 years, 9 months. 48lbs • Not overweight • (No booster)

  8. Crash Dynamics • A five-point harness system makes contact with the strongest parts of the body – the hips and shoulders, and transfer crash forces over those strong parts of the body...and into 5 points on the seat. (Britax USA) • The Iliac Crest (hip bones) isn’t fully developed until age 6-10. This crest keeps the lap belt in position. • Poor belt fit increases the risk of abdominal injuries.

  9. Crash Dynamics Booster vs. 5-point harness

  10. Crash Dynamics • A forward facing, top- tethered seat reduces head excursion: Not Tethered Tethered Weber, Kathleen; Crash Protection For Child Passengers: A Review of Best Practice. UMTRI Research Review, July-September 2000

  11. Seat Options • Many new seats offer rear-facing 35-40lbs and forward facing harness limits of 50+lbs • Tall children: look for high top harness slots. • Conventional seats for Special Needs

  12. Graco MyRide 65 • RF to 40lbs, FF to 65lbs • head pillow to 40lbs • infant insert: 1st harness slot • top harness height=16” • natural recline FFing

  15. Britax Roundabout 50 • RF: 35lbs, FF: 50lbs • Same harness dimensions as Marathon (16.5”) • No belt lock-offs, no HUGS. • Can tether RF • Can recline FFing to 33lbs

  16. True Fit Premier • RF:35lbs, FF: 65lbs • Rebound Energy Management System • Must use “upper seatback” headpiece after 22lbs. (not shown in picture below) • Has built-in belt lockoffs

  17. Britax Frontier • Minimums: 2 years, 25 lbs. • Max harness: 80lbs. • 18.25” top harness slot. • Booster can be used beyond 100lbs • assuming: appropriate belt fit, ears below top of seat, and expiration (9 yrs booster).

  18. Graco Nautilus • 20-65lbs 5-point harness • 30-100 HBB • 40-100 LBB • 100% of the base must be on vehicle seat • Debate about buckle being under child.

  19. Additional Seats Apex 65 20-65lbs harness booster to 100lbs *vehicle headrest Evenflo Triumph Advance 5-50lbs Britax Regent 20-80lbs Discontinued?

  20. Special Needs • A child may need 5-point harness beyond conventional seat offerings: • behavioral issues • muscle tone • medical condition • search safekids.org for a local CPST trained in special needs.

  21. Other Seats • Available for download on saferidenews.com • Missing some new seats

  22. Caregiver Education • Top tethering • Reminder about vehicle LATCH limits • Child may reach height limits before weight. • Harness at or ABOVE shoulders for Forward Facing. • Child’s torso proportion is key.
