Tuesday's Tech Tip: Why do some vehicle manuals warn that nothing should press against the back of the front passenger seat or be placed under that seat?

Here's the Short Answer
The warning applies to pressure against or objects under the FRONT PASSENGER seat (not the driver seat).  Advanced Air Bags (AAB), which are now standard equipment in all vehicles, use sensors to decide when to deploy.  Pressure against the seatback of the front passenger seat - such as from a rear-facing car seat or the feet of a forward-facing child - may cause a false reading by the sensors.  In a crash, the sensors might inappropriately react to this pressure and either inflate the airbag when it should have stayed deflated, or vice versa.  Even pressure under the seat - such as from objects placed under the front passenger seat - may affect the sensors.

Tips to Take Away - What Should You Do:
  • As a rule, it is best to make sure that the rear-facing car seat does not press against the front passenger seat (one vehicle manufacturer explained that you should be able to slip a sheet of paper in between the rear-facing car seat and the front seatback)
  • If a forward-facing child sits on the passenger side in the back seat, try to make sure they do not push their feet against the seatback of the front passenger seat
  • Do not put anything underneath the front seat (including medical equipment)
Now that I piqued your interest, please read the long answer in this fantastic article from our friends at Safe Ride News.

American Academy of Pediatrics Says Rear-facing Until Age 2 (at least)

REAR-FACING & YOUR TODDLER
    Evidence-Based Recommendations from 
Dr. Alisa Baer - Pediatrician & The Car Seat Lady

Accidents happen - but you can prevent injuries. Car crashes are the #1 cause of preventable death & injury to children in the US. Give your child the BEST protection possible - so in case of a crash you'll have no regrets.


I want to share with you new information and research published in the last several years that strongly recommends keeping kids rear-facing as long as possible. The American Academy of Pediatrics (AAP) has for many years now recommended keeping kids rear-facing until they are too big for their convertible seat, and new research published both in American and international medical journals fully supports this. Convertible seats are ones that start rear-facing and then convert to forward-facing for older kids; kids typically start using a convertible seat after out-growing the infant seat. 


A 2007 article in the journal Injury Prevention showed that 2 year-olds were FIVE TIMES SAFER riding rear-facing than 2 year-olds riding forward facing.1 A 2008 article in the journal of the AAP urged pediatricians to "implement what we know to be best practice: children should ride in a rear-facing seat to the highest weight or height allowed for use rear-facing by the manufacturer of the seat."2 The AAP further reinforced this message, publishing "New advice: Rear-facing car seats safer for children until they are 2" and a handout for pediatricians to give to their patients entitled "Keep your toddler in a rear-facing car seat until at least age 2 (not 1)".3 In June 2009 the British Medical Journal (a highly regarded peer-reviewed journal) published an article entitled "Advise use of rear facing child car seats for children under 4 years old."4 The push to keep pre-schoolers rear-facing is now a worldwide movement. The Swedes, who for more than 35 years have kept kids rear-facing until 4 years of age with extremely low death and injury rates as a result, are probably wondering what took the rest of the world so long to catch on.

As kids get older, their feet will touch the back of the vehicle seat; this is safe & comfortable. Ever watched a 4-year-old sleep with his chin on his chest? They never wake up complaining of a stiff neck! Kids' joints aren't fully formed, which lets them sit comfortably in positions that would be painful for even a limber adult. For this reason, a 3 year old can sit comfortably rear-facing with her legs crossed or in the "frog leg" position. Other parents worry about leg injuries; studies5 show that forward-facing children suffer far more leg injuries than rear-facing kids.

Rear-facing does not have to be boring! Older kids can ride quite upright so they can see out the side and rear windows. If there is a head rest blocking your child's view out the back window, you can usually remove it. By 9-12 months your baby knows you're there when you talk to them from the front - even though they can't see you. Therefore, you can calm and entertain your child with songs, stories - and for older children games of "I spy" - all while they are rear-facing. Concerned about car sickness? Volvo looked at several thousand pre-schoolers and found the same rates of motion sickness in those riding rear-facing as those riding forward-facing. Regardless of the direction your child rides, placing
them in the center seat with an unobstructed view out the front/back window will help keep the nausea away.

In the face of growing evidence that rear-facing is by far the safest way to travel, it is my recommendation as a pediatrician and nationally certified child passenger safety instructor that children ride rear-facing until at least 2 years of age - and ideally longer, until reaching the maximum height or weight for rear-facing in their convertible car seat, which for most kids is around 2-4 years of age. The weight limit for rear-facing is 35-40 pounds for most convertible seats, with a few seats going as high as 45 pounds. The height limit for rear-facing is that the child's head must be 1 inch below the top of the car seat.
