Another question - Air Jackets?

Won't work, before I made my microswitch contraption I made a flap cover
which covered the ignition key slot, It was supposed to nudge my
subconscious (to remove disklock) by having to lift it to put key in.
I just lifted flap put key in, started, and then fell off bike again,
(did not remove disklock)

I have an old ubolt lock that has a flat key not a round key.

When I used it regularly I used to have a bit of tubing that fitted
over the ubolt key. To unlock the ubolt to use it I removed the
tubing and put that on the ignition key.

Can't turn the ignition on with the tubing on the key.. so it's a good
reminder to unlock the ubolt and put the tubing back on the ubolt key.

Yes you probably have it wrong. You were probably misled by other
people who were wrong. The website states that 30kg of force is
required to activate the 'ripcord'. That's an awful lot of effort
before you actually do any harm.

So they do allow for idiots like me, Still think they should not exist
there are to many brainless lawmakers that will want to make them
compulsory.

 

Actually 30kg isn't that much. If I lent backwards a bit as I was
stepping off a taller bike there could easily be that much force on a
cord if I overbalance a bit given that I'm a bat fastard [1]

[1] skinny people would obviously be less subject to this problem.

 

Speaking as a 'forget - er' of disk locks I can see myself forgetting
the airbag jacket tab on an occasional basis as well.

I REALLY don't like the idea of them being required by law but I have no
problem with them being available for those who want to use them.

I tried that, it took me until next week to find my keys because the
weather warmed up and I was using my summer gloves and my keys were in
my winter gloves.

Now that's a useful tip, but neither my summer or winter gloves have
them (my previous pair of winter gloves did though).

It will have to be redesigned then, seeing that you have got out of there at
least once

 

Then Nev, if you had one and stepped off the bike, it would go off very
easily with your 130 Kg frame

 

Almost the same as with a car, with you getting a possible fine for not
having your seat belt done up before you put the key in the ignition.
So, you get in the car, do up your seat belt to be legal, then remember that
your keys are still in your jeans pocket, then go through the whole
rigmarole again

 

Actually I would think 30kg is a huge amount of force. The cord is not
attached to your entire frame... it's attached to a single tether on
your jacket. Tie a piece of cord to a corner of your jacket and tie the
other end to a 20kg bag of cement. Give it enough slack to let you take
about 1 step before the cord pulls tight. Now step away from the cement
bag with the same effort that you would if you had just taken a step
back from your bike and see how much effort is required before you start
to drag the bag along the ground. I'm guessing the jacket will try to
tear itself off your body before the cement bag goes anywhere, and
you'll have to exert at least a small amount of effort before you start
moving the cement bag. Now add another 10kg of dead weight to the bag
of cement and do it again. The website actually warns that if you have
a light bike, the bike might actually fall over before the 30kg force
required to activate the air jacket is reached.

If you're such a bat fastard who's prone to overbalancing when you get
off your bike you should probably be first in the queue to buy an airbag
jacket, but to protect yourself when you're off the bike, rather than on
it.

--

30kg dropped vertically 600mm on wire rope attached to a fixed anchor will
result in about 1Kn of force on the anchor.

How much force is required?

I imagine a 12 month replacement on certain parts as well.

 

I've never studied any physics. I have no idea how you came up with
that or what it means, but it sounds like enough force to activate the
airjacket - which sounds ideal for an unplanned stop situation where
rider and bike part company.

I snipped the bit about warranty because I couldn't actually work out
what you were alluding to.

Nev..

 

30 kg doesn't sound like much force when there's inertia involved.

Most people need the key in their hand to get into the car George.

Very likely in Queensland at the moment.*

*particularly if you are crazy enough to be riding a bike in this weather.

I could see it happening on my CBR1000RR street fighter. No fairing made
speeds above 160km/h a hang on proposition. Over 200 it felt like a gorrila
was trying to drag you off the back of the bike.

As long as the japs or germans built it that sounds absolutely brilliant. The
italians and english should never under any circumstances be allowed to build
anything that involves electricity, or as they call it, magic smoke.

What inertia? Don't you stop your bike before you dismount?
