  • 3 point seat belt

    I installed the fixed belts to 1/4 '" angle iron in the usual way, but I through bolted the angle iron to the frame. In the trunk/rumble seat area I installed two horizontal flat bars to the rear vertical deck pillars A-47461 & A47453. 0n both sides. The first picture shows a belt extension that is bolted to the top horizontal bar. I was to lazy to remove the cardboard panel for this picture, but will if more clarification is needed. That top bar is angled down in the rear for a straight line pull. The second picture shows the retractor mounted on the back shelf. I elevated the retractor to lesson the angle over the shoulder. This is not required but might help prevent a broken collar bone. The retractor is through bolted to the tray with 2x6 backing. The seat belt is very comfortable. The important thing to remember is try to keep a straight angle from the top of the shoulder to the upper horizontal bar rear bolt. Clear as mud I know. Bob This will work on any coup.

    WOW Bob, I think that is the cleanest way of installing a 3 point that I have yet to see, very well done on thinking out of the box!!
    You wana look waaay far up da road and plan yer route because the brakes are far more of a suggestion than a command!

      I have a coupe that is ready to assemble, that sure looks like what I need to work on. What type of belt retractor is used?

        Update: I could not find my receipt but I bought them online from WESCO PERFORMANCE Don't forget the seat belt extender under hardware. Call them they are very helpful. good luck Bob

      I bought them on line and will have to look it up and get back to you. Some retractors do not like to work in a horizontal position so if you go to local parts stores check them out first. Also remember you have to get the extender strap to go from the retractor to the Rumble/trunk reinforcement area.

        The same general setup can be used on a roadster. A few years ago, I attached a steel plate to the two body supports in my wife's '31. The retractors are fastened to this plate in the rumble seat area. The roadster package shelf is two piece such that I was able to put spacers between the two sections to provide a slot to thread the sliding belt through. Unlike the coupe, there is no need for a belt extender or having to mount the retractors inside the car on the package shelf. Works well and is just as easy as a modern car to put on and take off.

          I did not think of that,I am sure it would work on coups as well and would be neater. Would have to cut a slot in the shelf and line it for chafe. I wonder if the downward pull on the collar bone would be grater though.

            I don't think either your or my arrangement would cause collar bone injuries in a crash. I did research before my installation and found that so long as you didn't exceed 45* of the belt behind the seat, you would be ok. I have seen many photos of DIY belt installations where the belt is attached at the floor directly behind the seat. That is an invitation for serious crushing collar bone or spine injuries in a crash. For those wanting to install three points in tudors or sedans, using double racing belts over the shoulder joined to a single detachable tether anchored behind the rear seat works well. My '31 Chrysler sedan and '36 Auburn are set up this way. It allows the single tether to be detached to allow passengers to enter the rear seat and then reattached as soon as they are comfortably seated.

            Strange, I added three photos to my first post above and they appeared when I reviewed it after posting but they are not here today. Still getting used to this site and must be doing something wrong pasting photos.

              Seat Belts in 30 Coupe
              by dmaxweb
              First off, sorry for another seat belt thread. I've searched and searched for a clear illustration on the inboard belts.
              The inboard belts are bolted to the reinforced cross sill behind the tool pan - so far so good. How are the belts routed through/around the wood seat frame and/or the curved sheet metal at the back of the seat?

              Seat belts in rumble seat
              by Tom Rode
              I am searching for information on installing lap belts in the rumble seat of my A. I see many threads and articles about belts for the front seat which I am planning for my next project, but see no info on lap belts for rumble seat, where everyone want to ride. Anyone done this. Also looking for method for padding the area behind the front seat for those rear passengers.

              by Bill G
              Someone point me in the right direction if I am seemingly dumb.

              I have searched this forum and several other places looking for one specific reasonable answer. Specifically a decent anchor point for the center seat belt straps for the rear seat of a Tudor. Other than the very thin/flimsy metal floor pan of the Tudor, there is only a fairly narrow frame channel along the back edge....

              Pickup Seat Belts
              by KenB
              I’d like to install lap belts in my ‘30 pickup. I’m not understanding how to do so to option a 70 degree angle. I’m also thinking additional steel may be needed. Any direction on successful seat belt installation will be appreciated! Would retractable be indicated?...

              Rumble Trunk
              by Bikerider58
              30 Deluxe with trunk converted to rumble seat. Riders are few and far between, but I think the seat is cool to have.

              Any suggestions on a locking arm or rail to keep back from falling forward?

              After removing the seats for general use, I understand an area should be blocked off at the back. How much area?

              Pictures Showing Upholstering Tudor Rear Seat
              by Tom Wesenberg
              In 2014 our Model A club had a demonstration put on by Elizabeth of Classtique Upholstery, showing how to reupholster a Tudor rear seat.
              Elizabeth sure does nice work, and makes it look easy. Too bad I didn't have a video camera for this job. Notice the nice frame Elizabeth made to compress the seat springs while doing the upholstery work. The last picture shows the bead on the rear of the seat,...
