Today our expert Kat took part in a live Q&A session over at Road Safety GB for Global Road Safety Week!
The session was very busy, with lots of questions answered - the hottest topics were iSize and booster cushions.
Do you have a burning question that isn't asked? You can ask our experts at any time!
Child car seats which are tested under R44, are broken down into ‘group’ stages. The main stages are:
Group 0+ (infant seat)
Group 1 (toddler seat)
Group 2,3 (booster seat)
It is possible to have combinations of these seats, such as group 0+1, or group 123. Your question asks about group 2,3 car seats which are for children weighing 15kg, however, extended rear facing car seats are another option to group 1 toddler seats.
Rear facing children, after the infant seat stage, has been found to be safer. It is safer because a young child’s neck and spine are still developing, and their head is very heavy in proportion to this. In a frontal collision, which is the most dangerous and most common type of collision, a child’s neck is put under great amounts of strain. This is because the forward facing car seat secures their torso, but their head continues with the forward momentum. When rear facing, a child’s head, neck and spine remain fully aligned in a collision, which hugely reduces the force they are subjected to.
Countries which have their children rear facing until the age of 4 years have very low numbers of serious injuries and fatalities, and evidence does show that up to age 4, children are safest rear facing. Forward facing car seats have hugely reduced the numbers of children being killed or seriously injured, and we do not know how the misuse level affects the number of children getting hurt.
The risk of misuse is something to consider as well, as extended rear facing car seats can often be more difficult to fit – they are improving however and becoming easier to fit.
So in a nutshell, yes, rear facing is undoubtedly safer for children up to the age of 4, but it is important to ensure you fit and use the seat correctly.
Booster cushions are approved from 15kg, and may be used once a child reaches this weight, provided the adult seat belt fits across them safely (lap belt low on hips, and the shoulder belt running from their hip and across their shoulder). However, children are safest using a high back booster, over a booster cushion – although you won’t be prosecuted if you do use a cushion. Both high back boosters and booster cushions may be used from 15kg, up to 36kg/12 years old/135cm – whichever comes first.
Impact shield car seats spread the force of a collision over a wider surface area, which reduces the forces a child’s neck is subject to – these forces are lower than when a child is using a 5 point harness. The test dummies do not currently measure abdominal forces and there is currently no evidence available to show if impact shields are less safe due to abdominal loading.
There is little safety difference in performance between ISOFIX and non ISOFIX high back boosters – both will protect a child well in a collision. ISOFIX is beneficial however, as it keeps the booster locked into place when the child is not in the car. A loose booster is a very dangerous projectile if you were to be involved in a collision, and the ISOFIX removes this risk as the seat is attached to the car.
The research to show the safe amount of time a baby can be in a car seat has shown that the car seat can cause a baby’s oxygen saturation levels to drop. When tests have been carried out, the oxygen saturation levels have been shown to drop within 30 minutes. The ‘2 hour rule’ is generally thought to be the maximum amount of time a baby should be in their seat at any one time, although some organisations cite 90 minutes. There are other risks associated with infants spending too much time in their car seat, such as the development of ‘flat head syndrome’. Your baby must always use their car seat when in the car, but parents and carers should ensure they plan time for regular breaks of at least 20 minutes. If a car seat is going to be used on a pram chassis, it should only be used for quick trips, and the baby is safest being transferred to the lie flat pram if you will be out for any length of time.
Booster cushions are tested under R44.04 which tests for a frontal impact, rear impact and roll over - there is currently no side impact test required under R44. A booster cushion is designed to lift a child up enough so that the adult seat belt fits safely across their hips and upper body, it does not offer any protection for the torso, head or neck. A child is safer using a high back booster over a booster cushion whenever possible.
The 5x safer rule comes from a report which was undertaken in Sweden, which found that children were 5 times safer rear facing, than if they were forward facing in a booster seat. In Sweden, children are either rear facing up to age 4, or they are put into a booster seat – forward facing harnessed car seats are not available there, and so there is no evidence relating directly to them. What we have seen, however, is that Sweden has a very low casualty rate, whereas the UK rate is still too high. There is no doubt that forward facing car seats do a very good job and protect children in our cars, however, rear facing car seats do offer the best protection, particularly for younger children.
WHICH? take into account many things, as well as crash performance. One of the things which can bring a score down is ‘ease of fitting and use’ – extended rear facing car seats are considered to be difficult to fit and use, which is why they score more poorly. Impact shield seats score highly because they slightly reduce the force to a child’s neck and are considered easier to fit and use, and are quick to transfer between vehicles. However, based solely on crash performance, rear facing car seats are safer.
i-Size does require children to rear face to 15 months old, and they are allowed to turn forward once they are 15 months, as there is no lower weight limit. However, i-Size child seats do have a lower height limit, so a child will not be allowed to use a seat they are not tall enough for, even if they are 15 months. A child may use the infant seat past 15 months, if they are within the height limit of the seat –the height on i-Size infant seats is 83cm.
A non ISOFIX child car seat will perform just as well in a collision as an ISOFIX seat if they are both correctly fitted, however ISOFIX is considered safer as it is easier to fit.
With any child restraint that you buy, it is vitally important to visit a retailer who can give you advice and ensure the seat is compatible with your child and vehicle, as well as show you how to fit and use the child seat.
There are a number of swivel seats coming to market, many of which also do forward facing and are ISOFIX.
i-Size is both – it is a new regulation, but it is also part of an ‘overall’ regulation – which can become a little confusing!
The new regulation is R129, which i-Size is part of. i-Size covers phase 1 of the new regulation 129, and phase 2 which is looking at the safety of booster seats, is currently underway with completion aimed for 2016. Finally, phase 3 will be looked at, which includes all belt fitted only seats, the aim for completion on this is 2018.
So i-Size is a new regulation, but it is part of a larger regulation – R129.
The older regulation R44 is still valid and will be for some time yet, you do not have to replace your current car seat if it is not i-Size.
Good Egg Safety runs a national child car seat awareness campaign and we conduct child car seat checking events across the UK. We are just about to launch a Child Seat Checking Roadshow throughout Scotland. You can find a list of checking events on the website: www.goodeggcarsafety.com
We have checked over 21,000 child car seats nationally since 2001 and data from our most recent 5 year average (12500 checks) indicates that 57% of child car seats are incorrectly fitted or used – last year alone 71% of seats in England and Wales were incorrect and 64% in Scotland.
It has prompted the development of a powerful new advert which will be screened here on Road Safety GB’s GRSW site on Monday 11th May so stay tuned and keep checking goodeggcarsafety.com for all the new child seat checking events clinics being booked throughout this year.
Hi! I really appreciate what you are doing and got some good advice from you regarding our car seat so I hate to complain, but I'm wondering why the picture above has an infant that looks very young facing forward? I thought the law was rear-facing until 9 months and he doesn't look that old to me. Thank you so much for your help. (I truly don't mean to be negative or annoying.)
Thanks for your comment!
This image was taken when our expert was in the process of checking the child's car seat.
Although the law allows forward facing once a baby weighs 9kg (20lb), we always ensure that parents are made aware that extended rear facing car seats are available. We highlight the extra safety offered from rear facing to parents with babies in group 0+ car seats, or if young toddlers are in forward facing restraints. We want to ensure parents everywhere have all the correct information to hand to ensure they can make a fully informed choice for their child’s safety and we respect any decision that they make
