REFLECTOR: Safer seats

Tue Sep 27 19:13:28 CDT 2005

I'm with Ronnie and Chuck on this too...no need for big time lateral
cocoons like a race car driver who has significant lateral g to deal
with.  Plus side bolsters add width.   I have the benefit of 5 Velo's in
the shop here to make comparisons with.  

BTW if you are building a standard be careful assuming what fits in
somebody's XL in after market seats mightl not fit in yours.  The Velo
seat pans are narrower in the standard by an inch or two.  I drive
around in the Nissan Maxima.  The seat width is 22".  John T's Porshe
seat that is here measures around 20wide. I'm home now and can't
measure, but the Velo seat pan is around 17".  John's Porshe seat fits,
but that's about all.  ...and looks real nice too.  It doesn't leave
much room to stick papers/maps etc between the keel and the seat.  I am
giving some thought to making a nest for myself in cruise.  Also the D
tube in the door will eat up some lateral space to the outboard of both
front chairs.  Don't just look at the cabin walls fore/aft of the door
opening and figure that's your outboard line.  It ain't.  

If like, me you don't have rudder pedals in yet, and are guessing about
fore/aft placement...once installed the rudder pedal aft face is about
8" from the forward cabin wall.  I used a block of foam for a spacer in
the early going.  Now I also have a plywood frame to hold the assembled
Velo seat so i can sit in it and make adjustment fore/aft and well and
left/right.  I am favoring slightly to the outboard so I can have
stowage between seat and keel.

            Keith,

            I kind of buy into Ronnie's idea that side support seats
look comfy and provide a snug fit, but would be pretty uncomfortable on
long flights, as we all like to scooch around.  Side support in an air
crash is probably low priority as most of the 'action' is
linear/straightline whereas a an auto or race car is assumed to rock and
roll as well as suffer side impact, so the side support becomes much
more important.  Yes, it's understood that there is always the potential
for some side to side movement in an aircrash, but save for the
occasional cartwheel, most air incidents are straight ahead, hence the
seat/shoulder belts are in good position to do their job even without
positioning by the seat.

On the other hand, since this all came up in the context of
crashworthiness, those side bolsters would help keep you in position
under the seat belts better than flat seats during the gyrations of a
crash.  Something ELSE to consider!

Great looking seats - however something to consider:

Since most of our turns are coordinated - meaning there is minimal
horizontal G loads - the thigh and shoulder bolsters are not really
needed.  In fact they pretty much lock you into position and can make
the long rides uncomfortable in that you can't move around much.

So Jerry, which are you leaning toward. That bottom one you suggested
looks good. I think I missed any specific reference to memory- or
viscoelastic- foam though. Just said high density, I thought. 
    Looking forward to Toilet Bowl and detailed crawling around your XL
!

I have been looking at seats for a couple years.  John you picked out my
favorites when cost is no object.  However, there are many in the
$300-$500 range that are very acceptable.  What you may not have notices
is that these seat also use viscoelastic foam (aka memory foam).  Of
course with more structure you get more weight.  These seat are going to
be in the 25-30 lb range.

A particularly interesting seat in base size.

There are seats for race cars available that are very light and designed
for high speed car crashes.

Yeah; I wonder how many bars of gold it would take to get one (@$470/oz)
