The long length of the VW skinny inertia belts
must allow a frightening amount of stretch.
A friend of mine plowed a single seater airplane.
He had five point wide belts, and he still implanted his
teeth into the instruments- the belts were not
fastened very tight, but still stretched more than
you would think.
Has anyone installed four point belts with wide webbing?
My brother in law has a Humvee and strapped in a small
pro racing seat (the aluminum with super high sides) and
four point belts for his six year old. You can get a decent
seat for ~$200 and that should last until teen years.
Kids just love to get into these seats and belting up!
and there's no stigma of being in a 'kiddie' booster seat.
I'm considering doing the same for my son.
Any thoughts about is this a good idea or not???
And has anyone improved the stock belts?
couple of sites- look at the cheap $200 seats:
