Ok, Ive seen this ad wayyy too many times now and its really starting to annoy me.. mainly because I dont understand how it can be correct..

Whats with the ad on tv at the moment where someone is driving without a seatbelt and they say that since he's travelling at 30mph if he crashes his internal organs will smash against his ribcage and his aorta will be ripped from his heart and essentially he will die..

Now what about if he is wearing a seatbelt driving at 30mph ...or even 80mph... or other speeds that people commonly crash at... are we meant to believe that a seatbelt would stop his internal organs crashing about inside him?


Is it just me or does this seem a bit far fetched?

I think you should be asking why he manages to hit a car dead on looking straight ahead at it.

Needed the insurance money to pay child support and buy his 6 kids christmas presents in the current ecomonical climate

edit:1.15 arghhh its on again!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! "and thats how richard was killed"
 
I don't understand it either, my understanding is the longer it takes to reach a stop the less the forces inflicted, meaning the organ slamming situation would be worse with a seatbelt on?

The seatbelt locks at an earlier time meaning less force to be impacted on internally. If you just keep going more force would be generated. Crash test dummies might prove this. Don't know how.

If you never set off you have no forces inflicted.

The seatbelt is designed to stop you flying around the car hitting random objects. In addition it stops you hitting solid objects and the mushy bits inside you trying to get out.

It's not that difficult once you think about it.
 
Think about it, what would be more damaged?

Example: 1. a loose melon in a crate or 2. a melon securely strapped in a crate

That's the way I see it although it might be way off the mark.
 
the seatbelt stops the body thrashing about which in turn will limit the organs crashing about a bit too

i dont think many people hit something while still travelling 80 either. certainly not common!

most people have slowed down a lot before impact. i reckon i was down to 20 or so when i had a crash and i had a seatbelt shaped black bruise to show for it ! its a big impact

Yeah fair enough.. I understand that if you go flying around the car you will hurt yourself. What I am having trouble comprehending is the ad saying that the guys main artery to the heart will be torn from the heart by the impact.
Nice analogy ;)

You just don't feel the actual G-force when you're in the car then when an immovable object smacks! *out the windscreen*

because instead of him being attatched to the energy absorbing car when he stops he is stopping milliseconds afterwards when the car has already crumpled . so he gets the full force of stopping

im crap at explaining this

Scenario 1: Person driving wearing a seatbelt. Hits a random solid object in the road. Pre-tensioners go off, webbing is clamped. Seatbelt doesn't allow freedom of movement whilst vehicle falls to bits, holding the person in place. Person comes away with bruising.

Scenario 2: Person driving without wearing seatbelt. Hits a random solid object in the road. Body is thrown forwards whilst vehicle falls to bits. Body impacts on solid objects in front of it. Tough skeleton may fracture and break but would essentially stop moving. Mushy bits inside keep moving forwards and impact against skeleton/aforementioned solid objects. Mushy bits fail, person dies.

Vastly simplified, obviously.
 
The car can't slow down as much in a crash in the time it takes you to reach the seatbelt, as it can in the time it takes you to reach the dashboard.
