I need some information on leg room and knee angles on various buses.
I have a bum right knee. It only bends 31 degrees. The main reason I sold my MC7 was it hurt to drive it more than a few hours. So what I want to know is, are there any coaches with different driver seating geometry or are all of them about the same?
I know a 4104 and an MC7 won't work because I have had both of them. The Bluebird Wanderlodge I have now works but just barely, mostly because it has a tilt steering column. I can't set in my wife's Chrysler Town & Country either.
Here is the setup:
When I sat in either of my old buses, my right heel was not on the floor on the accelerator. It would hit the pedal about 2 inches up. If I run the seat back and down so that my heel was on the floor and the knee angle comfortable, I was too low and too far away from the steering wheel. I thought about modifying my MCI when I had it but don't want to get into the legal hassles. It would probably never be an issue but I'm not going to chance it.
Buses and 18 wheelers generally set like a kitchen chair; back straight up and knees at almost 90 degrees. Luxury autos and sticks and staples RVs tend to set like a recliner; back laid back some and legs extended.
I only have experience with old MCIs, GMs, and Wanderlodges. This group of folks collectively have probably driven everything available.
What say you guys? Is there an older coach around than sets like a recliner? Or has a long reach tilt wheel? Or both?

I have the same problem - my right knee has tendon damage and can't stay bent for a long time. I am going to look at moving my seat back several inches and tilting the steering column. I haven't looked to see how to do it yet.

From looking at my 102a3 manual, it was available with a tilt wheel. Mine has the straight shaft so I do not know how much the wheel tilted. Good luck to you in finding a bus to fit your needs.
This is the tilt steering in my 102A3. Forgive the mess :)

I am having tilt steering envy... Do you find you use the tilt?
I have a back issue that causes pain down my right leg when travelling for any distance in my Ford 3/4 pick up. It has tilt steering as does my MC12. The difference is that in the pick up the tilt mechanism is right at the wheel changing only my arm angle whereas in the bus it is more of a column tilt changing the angle at my hips. I have not put on any significant miles on my bus yet but I can see it being a godsend to change the angle of my leg to torso.
I am not sure if the tilt in the bus is to aid in seating or to aid in a comfortable driving position. I would assume it would not be hard to shim the column rearward (can't see any real legal issues on that one) but it would make getting in and out of the seat a little more difficult as you would probably have to deflate the air bag before getting out to make it easier to get back in. There was one seat maker (nope, can't remember which semi truck they were used in) that their design would deflate the seat automatically without any weight on it making access a lot easier.
Another note from my wife .... don't chinz out on the seats since we will be seated for extended periods of time. Very strange my wife saying to spend more money than originally allotted, it's not like they are shoes or anything ???
My 5A had a block of wood attached to the bottom of the go pedal for your heel to rest on. The PO put it on and i used it until just a month or so ago. Took it off and like the stock angle much better. If anything i think for me an angled piece on the top of the pedal might even be a little better.
Thanks all for the info so far. I can see I need to hunt up some newer MCIs & bribe somebody into letting me check the seat out.
Any more opinions? How about you Eagle and Provost guys?

me my 38-40 inch waistline and my steering wheel are intimate, there is no recline,no tilt and no variety.
i do have a fancy motorhome style electric seat... hardly ever touch the switches..
anyone with a high driver eagle would probably have the versatility you wish for...
I have a Bolstrom (sp) seat that is fully adjustable. Up down (change angle in leg) air control on side does all this plus tilt steering column, Inflatable lumbar. Tilt on seat cushion and adjustable angle on back. Bob
Hi, I'm not speaking from experience but the first thing that comes to my mind is to possibly move the pedals to a better location. Raise them, move them, forward or back, whatever it takes.
HTH,
Yes, I use the tilt. I also recently installed an air throttle - best investment ever for my bus! I found the stiff push was hurting my back on long drives. Just completed a thousand miles with almost no pain.
I just looked at the pictures again, and the tilt mechanism looks a lot like what I've seen on some school buses. May be a source???
HTH, Don

I have a TRW tilting & telescoping steering column, can't remember the exact model number now, which with the fully-adjustable air seat gives a lot of positions. Definitely go see what your local wrecking yard has from a Blue Bird or Thomas pusher: school buses with underfloor storage bays are often better equipped overall because they are used for longer trips than the usual daily school runs, so they often have better creature comforts. Another thing - is your seat angled slightly to the right of the steering column to avoid hip or knee pain? If not, that may be also worth considering.

My Gillig H2000LF has both tilting column and a Recaro seat which adjusts in about any imaginable way. I find myself making minor tweaks often while driving. Last week I was in a scrap yard in Atlanta which had several transits awaiting the crusher. All had setups similar to mine. You might look into adapting both items from a late model transit.

Tom, I went through several brands of bus and truck seats with air rides,I finally had Villia build me a non air ride seat with all the goodies and installed a telescoping and tilt wheel and adjusted the angle on the throttle and brake pedal to fit me that worked for me.
I don't care much for a air ride seat in a bus for me they were hard to get in and out of with the drivers section dropped on a Eagle JMO
Tom -
The least invasive seating position is basically a combination of right angles. By doing so, you decrease the impact on your lower back, which then reduces the risk of lower back injury/pain - which none of us want to put up with.
Ideally you should sit in such a way that a straight vertical line exists between your ear, shoulder and hip. Hip to knee should be at a right angle to that, parallel with the coach floor when your foot is resting on it. Your lower leg should be at another vertical right angle, but realistically, most bus seat/steering wheel combinations preclude that. However, studies have shown that if you can keep your lower leg to about a 15o or less forward angle from vertical, using your knee as the pivot point, that's still within the acceptable range for maximum comfort and minimum long-term problems.
I am not fond of air ride seats in a coach, since the ride's so comfortable anyway. The constantly changing angles between hip, knee and foot is aggravating and invasive. It's no wonder transit drivers go out on workman's comp claims for lower back injuries from putting eight hours a day in these things. Even worse if you have a manual gearbox!
IBME that the best ergonomic OEM seating was in GMC highway models, MCIs, Crown & Gillig skoolies. The worst were Eagles, Prevosts and Gillig Phantom transits. Flxibles & GMC transits were somewhere in-between.
FWIW & HTH. . .

My 91 Prevost has a lever you push and pull down for tilt. not much help but a little. Have electric seats and that helps also.
I have not done many miles in my bus yet (91mci102a3) but it is a ok fit for now . Has tilt and tel.column .I also have bad knees and have raised the stock seat as high as it will go . I'm also on the small side (5 9 165) so cramped doesn't usually become a issue for me . I am a upholsterer by trade so tweaking a seat is done to most of my vehicles.
We still have the same seats I bought from Camping World 18 years ago.
They are upholstered and recline, slide fore and aft and swivel.
They never get hot or cold and are absolutely comfortable.
I have spent some looong days in those seats.
I bought new leather seats but took them out after one short trip.
Momma wanted hers back, they sit side by side and match. She went back and sat on the sofa.
I didn't like them either.
I installed tilt telescoping steering wheel a couple of years ago. Scuttlebutt had it that it would be more difficult to steer with the smaller wheel. Balderdash! It drives the same and I fit better behind it.
Most of us are the only one that ever sits in the driver seat. Get one you like! The next owner, if any, can replace it if it doesn't suit them.
I too, think an air seat is unnecessary in a coach. I like them in trucks but they do nothing to make the ride better in a coach and like Clifford said, It would be harder to get in them as they stow at the max heighth.
