  2. Hello.

    My van was the same as yours but I did some changes which made fitting the seat belt bracket much easier.

    Firstly I got rid the icebox down the side and rebuild my seat to be full width, and secondly I rebuilt the side wardrobe so that is was slightly shallower (in line with the ceiling cabinet). This meant that the seat belt mounting point was then outside the wardrobe, and I could then also open the wardrobe door most of the way even though my wider seat was in front of it.

    I'll see if I can find a better photo. I've sold my van so can't take any new ones for you!!

    Nick...

  3. Sorry, have had a look and I think those are the best photos I have showing the belt brackets.

     
  4. I am hoping to get away with not removing the icebox and rebuilding the bench full width. I might get my dad, he's a retired cabinet maker :), to make me a new rear cabinet that is shorter, like yours, in order to leave the seat belt bracket exposed. I have removed the factory wardrobe cabinet, had rivnuts installed for the lower mounting point (both sides), and I have been mocking up the set-up using my front passenger seat belt (before I order new 3-point belts for the back) just to study the angles and the path of the belt.

    I am posting these pictures of the mock-up for feedback. The issue, as I see it, from my non-engineering, non-scientific experience, is that the top mounting point of the shoulder belt loop is too far to the side of the shoulder. If I am seated in that position, then the belt wants to slip off my shoulder. Using the child booster seat with the shoulder belt loop (as shown in the pictures), the seat belt will be properly guided across my child's torso. However, as that shoulder belt leaves the booster seat towards the top loop it's angle is clearly not what it should be. It is too far to the side.

    When I pulled on the belt straight forward it seemed to restrain without pulling the seat sideways. Obviously, that's not an accurate real world test.

    So the life and death question is: Will this be safe in a hard stop? or in a collision?

    Maybe some of you with a more engineering or science background can weigh in. Thanks in advance.

    Hi.
    I"ve had to look into these brackets because of having an early bus with a fuel filler pipe that affects how you can fit them ... and have a special interest as an Osteopath having treated the effects of perfectly fitted seatbelts, never mind fettled ones.
    What you're proposing, for an adult, will be just a glorified lap belt, with the top section coming in across the top of their arm.
    The problem with lap belts is that the top half of your body can still jack-knife forwards, with the potential for serious pelvic injuries of various kinds.
    So it could do with being higher if possible.
    Even if you can get the belt to track over the front of the shoulder, if the belt comes across to an adult's shoulder at too flat an angle (or worse still, on the rise) in a "hard stop" the shoulder is in effect pulled downwards as opposed to just being blocked from moving forward.
    This can cause severe spinal compression injury.
    The slight inward slope of the glass limits just how high you can go, but worth the faddle IMHO .
    The fact that you're lengthening the distance between the swivel bracket and the shoulder is flattening that angle, which is negating the height advantages of the bracket ......

    Im no engineer but I can’t see that ending well. In a crash I’d imagine the seat will fly forward and try and swing towards the window, probably resulting in a face meets corner of sink unit scenario.

    It’s a no from me as well... but on a less technical and more “it doesn’t” look right basis.

    Are you able to fabricate and weld? Taking on board what the osteopath said, it might be an option to fabricate a bracket from the factory mount points, across the window and add a mount to the roof rail... a bit like some estate cars and SUVs do.

    Alternatively, for a less obtrusive method, some have welded in Isofix... but with both ideas you do not have the benefit of £££££s of R+D and testing to fall back on in an accident!

    With our nipper we tried a simple Joie Elevate seat on the seat adjacent to the window with a Davidoft bracket and a Volkswares bed... we just could not get the angles at the bottom to stop the seat sliding out. I eventually conceded that it would be better to use the front seat with the better belt geometry for the nipper + car seat and put the mrs in the back.

    The added benefit was a sleeping child in the passenger seat and full control of the radio!

    ... just put the radio boss behind you rather than the little one if you can?
     
  9. Hi there

    I have these if there any good to anyone

    I ordered them six years ago and went with a different set of belts if these are any good to someone let me know. I’m happy if you just pay the postage from Australia where I live.

    check the number and make sure they are going to work for you. I haven’t even opened the boxes.

    @jenannew this is what you need to fit 3 point belts in the rear

  12. @davidoft I don't know if you're still on the thread; haven't seen you post in a year. Still making these? Still doing the covers, or ever expect the covers to become available again?

    Cheers,

Really not sure of anyway to avoid this ? but not too worried as they could easily be tucked out of the way when not in use.

  15. So, as far as I can tell, this uses the seat belt mount below the window, and then the bolt hole for the backrest catch lower down, right? My bolt lower down won't tighten up, it's like it needs a longer thread to reach the hole - what do you guys have for the backrest catch bolt? Mine is like this -maybe it was a Z-Bed change back in the day?

    I think I need a much longer seat belt mounting bolt, too

  17. Thanks,
    I have fixed, non inertia belts fitted currently and wonder if I would have to change them if I used the extenders. If so: do you know what seat belts are recommended for the rear?
    They are only used periodically and were fine when the kids were smaller but are pretty uncomfortable and probably not that technically good now...

    1624883247992816843151.jpg Not too familiar with the Devon interior but securon belts are an inexpensive good quality brand .Fit the belts and brackets and just change /modify the bed as you go along .I had the large rear cushion cut and stitched so not to foul the belts .
