    Few Questions about buying a Tilite TR

    Do tilite have adjustable angle backrests on their chairs as an option? I seem to remember they had this option a few years ago or maybe just a false memory...

    And by the explaination on their order forms you have to calculate the dump of the seat to determine the backrest angle... That being said, If my new chair has 5" dump... the order form looks like I should have a backrest angle of 80 degrees.

    I'm pretty sure I'm reading too much into this coz my innitial thought was that the amount of dump was irrelevant all you needed to know was how far you wanted to lean forward or backward... What's your thoughts?

    If i want to get the ride designs (or another 3rd party backrest in the future) is there anything I need to be wary of... I've looked briefly into it, so I'm not too sure which backrest I will get in the future...

    That's it for now, I'm sure more questions will present themselves as I delved deeper into this order form...

    Thanks in advance.

    As I understand it, tilite has adjustable angle backs that are adjustable with tools. The kind that you would set and leave. I'd imagine that as long as the angle you put on the order form is in the ballpark, you're going to have the exact angle set once you're in the chair and then might change it up slightly as you use the chair.

    Quickie has a different kind of adjustable back angle, with a piston locking type design to select different options on the go/in the chair. The back angle was my biggest concern with my chair, the only types I found were those and then adjustability offered with the hardware of specific hard backs.

    You are right -- you can adjust the back angle on TRs -- there's a multi drilled and tapped plate that allows the back frame to pivot to the main. 5" of dump is alot -- are you sure you need that much? -- I have the TR, great underrated chair; you won't be disappointed.

    If you order an adjustable back, the angle you select on the form is just where they will set it for you at the factory, you can readjust it to the other settings you see on the form yourself. Don't think you are stuck with the setting you select.

    Dump and back angle are two separate things when ordering, you do not have to consider one when figuring the other.

    You cannot adjust the dump on a TR, what you order is what it will be. Other chairs, like the ZR's, Aero Z, etc., you can adjust your rear seat height (RSH).

    Minor clarification that I know Brianm is well aware of. The dump can be adjusted on a ZRA, but not the ZR. The latter has a fixed rear STF height.

    Also keep in mind that even with an adjustable version of any of these models, changing the STF heights will also change the effective front frame angle of the chair (See attachment for an example). Therefore, you want to have a good idea how much dump you want before you pull the trigger and order the chair. CAD drawings are always a good idea.

    Sorry or the late reply...

    5" inch was just an example to make the point easier to understand... Although I have a chair with 2" of dump and it feels like nothing... I don't trust going down inclines
    without lifting the front wheels off the ground... Not that its a regular occurance but I have been carried down a flight of stairs and had to hang on for dear life for fear
    of falling out...

    If I were to have a lot of dump in my chair I would most likely have to shorten the seat depth... Correct?

    SCI_OTR I saw the tight Top End wheelchair you spec'ed, that just looked like it was all wheel and no frame... That's what I am looking to achieve although I'm not sure what are the ramifications... I know a poorly setup wheelchair can cause all sorts of problems... The chair I have now for some reason causes serious shoulder ache... not sure what design of the chair causes this. I'm pretty sure it's the chair doing this as the ache disappears as soon as i transfer to the bed for instance... What's your thoughts?

    I had another thought about CoG... I have no clue as to how much I need and I've seen some TR's with a bar that's parallel to the ground. I wouldn't mind this as an option so I could tweak the CoG to get it right... How would I go about specifying that as a requirement? I'm meeting up with a OT to help spec out this chair but I dont hold much hope on their ability.

    I believe all TR's are built with the lower bar parallel to the ground (ignore non-TR pics). If they weren't, adjusting the CoG would change the rear STF height.

    Whether or not the frame is square (i.e., larger CoG adjustment range) depends on several factors (from page 8 of the TR YR order form):

    The COG is adjustable on the TR. You are aware that the TR is a box style frame and all have this ability, yes? See mine at the link below with CAD drawings, Post #4.
