I removed the front bolts and put 16 quarters (4 piles of 4 each) under the bolt-spots and then bolted them back down.[/b]

Let's see: 16 quarters = $4.

I couldn't find that many around. (My wife steals them for parking meters!) So I used dimes and nickles to attain the proper value.

When I sat down in my modified car, the seat fell over backwards and I cracked my head. Where did I go wrong?

I'm getting increasingly annoyed with my Prius seats (like most people with leather).

Today I decided to do something about it. I removed the front bolts and put 16 quarters (4 piles of 4 each) under the bolt-spots and then bolted them back down.

I'm using quarters as shims until I get the proper angle. Next I'll pick up a bunch of washers I think and make it more permanent.

Bad idea. You're creating a wedge shaped failure plane for the bolts. You don't want your seat to come loose from the floor in an accident.

Perhaps you did not read my entire post.

This is temp to determine the most comfortable angle. Then it's off to the hardware store to use washers instead.

It is unreasonable for a 1/8 washer to cause the bolt to fail. I request that nobody posts any more "you're going to die" replies and instead who has done this before to get their seat comfortable? [/b]

You can request that, but that's not the way things work 'round these parts. You're publicly posting about a significant modification to a critical part of the safety system of the car. Whether your modification (using washers, quarters, or silly putty) is safe or not is part of that discussion.

Someone could easily assume that such a mod is inherently safe. But the reality might be that it dramatically reduces the strenth of the seat.

I don't know if it's safe or not and part of this discussion is and should be how we can assure that anyone else who considers doing so is safe. I, for one, welcome informed discussion of the safety portion of the issue.

Dude, I read your post. Did you sleep through physics class? Putting washers around the bolts is no different.

If you want to make the seat angle more comfortable, remove the seat from the car, remove the upholstery, cut the base, weld it back at a different angle, re-install, done.

edit: if you don't want to make it that drastic, just remove the bottom upholstery from the frame, insert a foam wedge underneath, and re-install.

make sure you get the right torque for the seat bolts, that's critical and is mandated by federal satefy standards down here in the states.

this will very likely warp the seat track, because the bolts go in at an angle and the straight downward pressure of someone sitting on the seat will warp the angle. seat tracks cost around $1500, but more importantly this places you in peril because the seat could easily be ripped from the seat track during an accident.

that said, now you know what you're getting into.

Yep, that too.
