Which is real junk imo. http://pediaa.com/difference-between...ron-and-steel/

    I may be wrong at work we called red cast iron as just cast steel junk. We had so many problems with that red chit. Its just a cheap cast iron I guess. The part that broke on his chair and the ones I have on permobil should have been made from steel. There are many different kinds of steel.
    Without separating the piece and inspecting that break, I would hazard a guess that it is quality Chinese cast steel or cast aluminium, commonly known as 'shit metal'.
    They build bridges and buildings with the stuff down this way.
    IMO there should have been more gusset designed into the part.
    It is not as if people in chairs are able to take evasive action when these items fail; we have to go in what direction we are taken and hope for the best.
    We put a large amount of trust in these manufacturers with an expectation that we will be safe when using the equipment.
    Ironside, are these chairs subject to a annual, biannual or 5 yearly inspection?

    Wheelchairs in the United States are not subject to any inspections after purchase. In the United State, wheelchairs are regularly eligible for replacement every 5 years.

    So it could be assumed that a 5 year life is designed into the chair?
    I am not sure if that 5 year eligibility applies down here; I will look into that, thanks.

    I never knew that. Thanks for that bit of metallurgy!

    The bracket that failed is attached to the backrest so is always going to be under a certain amount of pressure when you are sitting in the wheelchair. I don't tend to use the recline much because it puts you more at risk from Shearing on your backside. So when I tilt right back I am using the seat tilt function. Obviously as soon as you start leaving back gravity well take over and you will put more pressure on this bracket. However, I think the bracket should be strong enough to support the people who are using the wheelchair.


    The engineer for Permobil here in the UK has told me that he is ordered the spare parts from Sweden. If they can't get them here within the week then something is wrong with the company. Also, they must have them in stock because they are still manufacturing the wheelchair so parts will be sitting ready for assembly.

    I got my mate to have a look at my chair today. There are two brackets either side of the seat at the back. One of them holds the bar that connects to the motor that operates the reclining. If the other bracket had broken than the back would not have collapsed. However, there is absolutely no safety built in to stop the back collapsing if the brackets on the power side breaks.


    Does anyone know if they Permobil chairs have been crash tested? I was looking at various other power chairs including The Storm. Several of the chairs I looked up have been crash tested. To be honest, I've never been particularly happy with the backrest on the Permobil, it always seemed slightly flimsy. I wear a chest restraint when I'm driving my van. In fact, it's one that is advertised by Permobil. I was in a serious accident I would be very surprised if the back of the chair didn't collapse forward.


    I'm going to take the bracket off the chair before it's fixed and try and find someone who can test it for me. I want to find out exactly how strong these brackets are and if they are actually made of a quality material. If you think about it, these brackets are one of the most important parts of the wheelchair, without them the whole back collapses. They should have used the strongest material they could obtain.

    Permobil Power Wheelchair Crash Test Results: https://permobilus.com/wp-content/uploads/2017/08/Permobil-Power-Wheelchair-Crash-Test-Results-Condensed.pdf

    If you do an internet search "Permobil Wheelchairs Crash Testing," you'll find information on the individual chairs. It should be noted that not only the chair, but your tie down system has crash test data that is important to the over all performance of the chair and tie down in a crash.

    When you purchase a wheelchair privately in the UK you are responsible for its upkeep. In some parts of the UK you can obtain wheelchairs and what they called the "vouchers scheme". Again, if you use the voucher to purchase privately you're responsible for. However, you can go to a recognised mobility specialist and choose a wheelchair which will be maintained for you and serviced annually I would think.


    My Permobil Corpus 500 was purchased privately in 2011 so that makes it just over six years old. As far as I'm concerned a chair costing ?15,000 should be manufactured of good quality products which means it will last a lot longer than five years.


    It would be interesting to know to what extent they crash test these wheelchairs. It scares me slightly when I see people that seem to be one lying on chest restraints whilst driving. I always wear a seatbelt, both around my waist and diagonally across my chest. My seatbelt has been modified slightly. I can hold down a toggle switch and the seatbelt will tighten. Supposed to give me not only a seatbelt, but also a strap that gives me a bit of support. However, I still prefer to wear a chest strap for stability

    US wheelchair testing is RESNA WC19, try this as a start point https://mobilitymgmt.com/Articles/2017/06/20/understanding-wc18-special.aspx European CEN/ISO as usual more complex this testing lab has some downloads https://www.tuv.com/netherlands/en/w...hoCIIQQAvD_BwE

    The ISO standard is available off the ISO website https://www.iso.org/standard/40993.html at a price! I have to buy the ISO cycle safety standards and get them from an Estonian site at a lot cheaper price.

    For what it's worth, I've always had excellent results with Permobil support. They've seemed very well-organized and I've always been able to find someone who cared about whatever issue I was having (I've been using Permobil for 13 years). I do think it's best to get a chair checked at least every 6 months, not every year like some suggest. And carefully. (I'm lucky in that my DME technician is excellent, which is rare I think). But I do not know how something like this could be caught in a maintenance checkup, that is, I don't know how the technician could know if the part was due to fail.
