    I just don't see how a tubular frame would work in the confines of a M72 cockpit. Using the ideas I already talked about, I would take a piece of scrap 1/4" plywood about 6" wide and whatever length needed to go from the floor of the cockpit to the top of the helmet and slide that vertically in behind the seatback. His weight against the seatback will keep it in place along with the shoulder harness. Then I'd make a helmet-sized U-shaped bracket out of PVC pipe (3 straight sections connected by two elbows) and through-bolt that to the plywood. Use some pipe insulation (or a $1.00 "swimmie" from the Dollar Store) on the PVC so it'll grip the helmet without vibrating and still let him move his head around a bit. Does that make sense?

    Try a plastic chair like this, but preferably one with the legs screwed to the underside of the base.

    http://cgi.ebay.com.au/ws/eBayISAPI.dll?VISuperSize&item=310443295035

    Sorry, but for some reason I can't post a picture so I've put in a link.

    Go to a wrecker and get a headrest and a few seatbelts. When you tell them what it's for they should give them to you.

    Fit the seat in your sidecar (without the legs) and work out the angle to the front. Match the front leg to that angle and mount a plywood section. The seat supports the body, the plywood the legs and the headrest the head and neck.

    Mount the seatbelts where needed with scrap sheet steel and screws. Place sheepskins or foam over everything to stop sores developing.

    If that doesn't make sense, I can draw up a sketch if the damn computer will let me.

    Howdy DRONE,

    I see now what your talking about, looking at the seat in my M72 it didn't look like anything could be placed behind the seat. I have NOT taken the seat out so I have no idea whats behind it, thanks for the suggestion.

    Howdy oppozit,

    I understand what your saying, I just don't want to be drilling a bunch of holes in the fiberglass tub. Thanks for your post.

    race sixpoint systems have an expire date. you might contact a local race shop and find somebody that has put a new harness in thier car and would donate the old one for such a worthy project.

    If you remove the seat back you will find a strong bulk head. The way I would look at doing this is to attach a support to the rear rack of the bike. If you wanted to some day go some where with your friend he will need his chair when you get there. I would go with a Harbor freight cheap trailer. We once built a rig for some one with MS. We mounted a folding "cherry" picker type hoist between the bike and the sidecar. It required a support on the sidecar side to the ground as there is a lot of weight hanging out quite a ways.
    Let me know if we can be of help.

    Howdy Jay,

    Thanks for your suggestions but what everyone seems to be forgetting is I will only be doing this ONCE, and we really won't know until we try if Rick can actually ride as it may be very difficult for him to breath. I am looking for a very simple way to secure him into the sidecar, something that can be easily built, perhaps just a board replacing the rear up-right part of the seat so Rick can be strapped to it. If this were to be something used on a regular basis what you are suggestion would be great but its not needed for this particular situation.

    Jay, as you built the rig, perhaps you can advise me on this, I have NOT taken any parts of the seat out of the sidecar since I brought it home; could the rear up-right of the seat be easily taken out and temporarily replaced with a taller board that a four point harness could be anchored through?

    Cob,

    What your doing is a really great idea.

    Based on what you posted earlier I am assuming your have a working width of 17".

    Based on that assumption I did some research and here is an option that does several things.


    • Provides support to the head
    • immobilize the upper body and lower body around the hips
    • Is one piece which can be installed in place of the existing seat, attached to how ever the existing seat is attached
    • Has provisions for 4pt or 5pt seat harness
    http://www.summitracing.com/parts/kir-36500/overview/


    This might be the best answer to what your looking for based on the requirements outlined in prior posts.


    You also need to make sure there is enough leg room for him or as other has suggested have at had several pieces of high density foam that can be used to arrange his body position.
    padding etc for the seat would be taken from his existing chair etc.


    What you really need are the following measurements.


    His current seat pad width (which I assume is anatomically correct for his hips).
    His current seat back height for head support.


    Those two numbers will help to identify what seat frame off the shelf might be applicable if any.


    Hope this helps.

    I think with it originally being a one time use thing and the distance thing I would when on site pull the tub, bolt a couple planks on the frame and strap the wheeler chair down with a couple ratchet motorcycle tie downs. Won't win any points for pretty but it'll get the job done. Plus side the chair already fits Rick so securing the chair will be comfortable, safe and easier than properly fitting Rick into the tub. Getting set up for a putt around town seems the easier part. Hauling whatever you build from WA to TX would be tricky or expensive. If a flatbed platform works ok, it'll be easy to store at Ricks if you guys decide to do it again, plus you'll have a shake down test run under your belt and aware of any mods/tweaks needed.
    Materials for either flatbed or tub mods can be had in TX and prolly other folks around that could help with any tools needed. I vote whatever you do, build it on location.
    Good luck...cool project.

    Hi Cob, The seat bottom lifts out, The seat back depending on when we did the change over is either held in with two screws from the in side of the trunk or with two wing nuts.

    Howdy Jay,

    Thanks for the information, I have been having to much riding this rig to even thing about taking it apart, I'll pop the seat sections and have a look at what I have to work with.

    Or, fly him over here and i'm sure my customer would give him a ride in this:

    Howdy All,

    I guess I should have up-dated this thread, I took advantage of Gary's offer to help build what I had in mind, this is what we came up with, it met ALL of my parameters, EASY, CHEAP, FUNCTIONAL. Thank you Gary for helping with the construction, thank you Tom for the loan of the five-point harness. Please excuse the ugly guy used as a model As Rick and I are about the same size I used myself to gage measurements and fitting. Padding will be added to the support bar as needed when fitting it to Rick.

    Gary working on part of the support structure.

    A trial fit to see if the bends are in the right place.

    Gary welds in the cross piece.

    Everything bolted in place, its adjustable and strong, it will work well.

    Thank you Gary for your help in building this head support, I appreciate your generosity and hospitality whilst at your home over the weekend, I do look forward to doing some hack riding with you this coming summer. :clap:clap:clap

    Well done. Maybe help/inspire others to try as well.


    Cleatus?
