What are the safety issues of having a childseat on the front seat?

Question

Assuming the following, are there any safety reason to not put a child in the front seat? I am looking for a technical answer and not opinions e.g. the car chassi is stronger on the rear

Assumptions * child up to 5 yo * airbag is securely turned off * childseat mounted properly * car model is of high safety standards e.g. Volvo * medium/large size car * model is post 2010 * front seat moved all the way back

Ps. This is a theoretical question on car/child safety and not intended to be used by anyone to decide on child safety.

Answer 1

SAFETY RISKS

• There are more violent front and front/first half collisions than from rear
• The engines are usually front mounted, on violent collision it may shift towards inside the car
• The windshield, even with modern technology, can get pieces into the car. They are designed to not to shatter, but they break and they can displace towards inside.
• In a case of incoming collision, it is known that drivers instinctively and almost unconsciously will turn in such way they shield them with the passenger side, i.e. if left hand drive, they will turn left sharply to try protect themselves with the right side of the car
• Children can try to play with car's commanding elements, like electronics and shifter, therefore demanding attention from the driver, who should actually paying attention to traffic
• In some cars, the air bag can actually suffocate the child since their low profile when in the front seat

SOME SAFETY BENEFITS SEATING CHILD IN REAR SEATS

• The child should be placed behind a seat, but not too close to the doors, that way she/he gets protection by the seat cushion and profile: on front or first half collision there are many items that can fly towards the rear of the car, like mirrors, items placed over the dashboards, etc
• The rear seats are probably the most safe place inside the car, since they are surrounded by the front seats, and the rear seats back. To some extent, they act like shields
• Children can play with whatever they want, without adding a physical distraction to the driver

The Joie Stages car seat is certified for use in front passenger and both rear outside seats of the Volvo S60, S80, V40 and V70. Information from the manufacturer is given here.

This seat is just one of many examples of a seat certified for use in such a way across the UK and EU. They give the specific guidance that the rear seats ought to be given preference and that it should only be fitted rearward facing in the front if the passenger air-bag is disabled.

This guidance is not unique but you should always check with the manufacturer of your specific seat for certified fitting positions.

I personally favour the front passenger set when fitting a baby seat in my Mk1 Golf Cabriolet because this seat is equipped with a 3-point harness and the rears have just lap belts.

EDIT: I would add that the certified fitting position for this seat in both Alfa Romeo MiTo and Guilietta is front passenger only and not the rear seats even though these cars both have rear bench seats.

Once you take out the obvious things like turning off the air bag it is all just simple statistics. You are more likely to survive or not be injured in the back seat this study shows that you are 29% more likely to survive a crash in the back seat and being in the middle of the back seat gives you another 25% boost over that.

This kind of makes sense if you think of the front seat as a crumple zone for the back seat. Sure, you can come up with a case where is might be better to be up front. But the actuaries still say the back is better, and if there is anyone who knows about life and death it is actuaries.
