When children are younger, they use a child car seat that contains a harness to restrain them. This seat is fitted into the car, where it normally stays strapped in, so even when your little one is not in the car, their seat remains restrained.
When it comes to your child moving up to a booster seat, both the seat and the child are restrained with the adult seat belt.
This means that unless you buy an ISOFIX booster seat, you need to remember to strap the booster in when not in use.
An unrestrained booster will multiply its weight by the force of a collision, so if you have a crash when your child is not in the car, but their booster is sat on the back seat - you have a very heavy projectile waiting to hit someone!
Spot the error! Take the above child seat, the Britax Adventure. This seat is known for being lightweight and portable, so it is easy to move between vehicle's. This child seat weighs just 3.9kg. In a 30mph collision, the seats weight will be multiplied, and when the seat flies forward, it will hit whatever it impacts with a weight of 117kg - or 18.4 stone! If you have a little one sat next to the seat that is flying around, or a passenger in the front, or even if the seat is behind you as a driver - 18 stone hitting the back of the seat, or a person is not good news! So for the safety of all, remember to strap in your non ISOFIX booster seat!
ISOFIX boosters don't need to be strapped in when your little one is not in the car, because the ISOFIX provides a rigid attachment to the vehicle. Just one of the great benefits of ISOFIX! Both ISOFIX and non-ISOFIX booster seats offer great protection for a child, but remember to strap in the non-ISOFIX booster when your child isn't out and about with you!
