SFI 38.1 and reclined seating position
« on: November 13, 2011, 05:29:01 PM »
Hi

What are people using for SFI 38.1 compliance with reclined seating?

The Hans site references up to 40°, my seat is 60°, any heklp would be good thanks.


Thanks

Hi, Jon.

You're new - welcome aboard. 

There's a search function on these boards, upper right hand corner, and believe me, we've discussed this issue to the point of fatigue.  :-D

Just enter SFI 38.1 into the search box, and you'll see more opinions, questions and advice than you would think imaginable.

60 degree layback - What are you building?

Again, welcome aboard.

I've taken the liberty of adding locations to the avatar space for a few of the new folks -- as well as sending them invitations to fill out the location blank in their Forum profile.  I doubt that Jon is really from the town of Maine, Arkansas -- but maybe it'll get a rise out of him and he'll correct me.  It's worth a try.  There's no easy way that I've discovered to require new folks to fill out the location part of the profile -- so I've gotta try something new, I figured.

Jon, not SSS Jon, we use the DJ Safety device.  We are reclined about 75 degrees or so, laying down with just the head and a little bit of shoulders up.  Here is a pic from a few years back, when we were not using the DJ.  We just added the DJ HNR harness, it doesn't take up much room.

Please post a picture of what you are trying to fit

Hi

Thanksfor the welcome, sorry I didn't introduce myself, I've been lurking & searching for a while but haven't posted before.

I'm in Brisbane Aus, just up the road from Maine Arkansas.

I'm putting together a streamliner bike slowly, i don't have a build topic, starting on seat dimensions & want to get a 38.1 device before I start metal work to make sure it all fits.

Have found a lot of discussion on 38.1 but couldn't find anything on what people are using for fairly low seats sorry.

Stainless, the DJ units don't specify an angle like the HANS units do?

Thanks
Jon

Jon, no it does not, we use it in both cars.  The streamliner sits up, the lakester as you see is a lay down.  The issue, the DJ is not yet SFI approved, it is still in testing and refinement to get approval.  The scta has accepted it as of now, I know Joe is working on certification and plans to put tags on all devices he has sold when it is finally certified. 
Max also runs the DJ in his streamlined bike.  The nice thing about it is the device is all straps, so it does not take up any room in a tight vehicle.  There are no hard collars or components to hang up on when exiting. 

Note to Tony... every run in the little car is a record run....  :-o  and requires your undivided attention.  BTW, 245 was a hoot...  :-D too bad it only ran 8 miles instead of 10  :-(

It looks like DJ Safety is discontinuing the DefNder line.

From the SFI site;
Please note that there are products from other manufacturers such as DefNder and Leatt Brace that were previously certified and labeled as meeting SFI 38.1. They are not currently listed on the SFI website because they are no longer in new production. However, any devices still in the field or at retail outlets that have SFI 38.1 stickers on them were properly tested and certified at the time. The certifications for those devices remain valid.

Specification 38.1 - Head and Neck Restraint Systems
HANS Performance Products - HANS Device (All Series)
Safety Solutions R3 Device
Safety Solutions R3 Rage Device
Safety Solutions Hutchens Hybrid Pro Device
Safety Solutions Hutchens Hybrid Pro Rage Device
Safety Solutions Hutchens Hybrid/Hybrid Rage Device
Safety Solutions Hybrid X Device

Is anyone using any of these with a seat angle of around 60 degrees or steeper?

Thanks
Jon

Jon--I know that one of the Safety Solutions devices is being used in Charles Markley`s` laydown Lakester and , according to him, works well. He almost qualified on the Green Bros 275 record last year. Do a search for Ravenna Garage Lakester....It is about the same laydown as Stainless` Bockscar...

  Kiwi, not to discredit what you are saying, but Charley Markley drives using a periscope which would in my opinion not require the same "angle of attack" for the wearer.........  just my perspective.
  As far as the SCTA requiring the use of a SFI 38.1 while allowing one manufacturers products to be used without that certification could certainly raise a few eyebrows.
  One has to wonder if the new model fails the SFI testing will refunds be given?          Bob

In Aus it needs to be SFI, so choosing from the SFI list is the only option.

Have been in contact with DJ for a while re buying a unit when it was SFI approved, doesn't sound like its happening.

Dont think the HANS units would work, the bit sticking up the back would be a bear & they dont make a unit anywhere near 60 degrees.


I sent an inquiry to Simpson & got this reply:
      "Your best option would be the Hybrid Pro. 
       This device does not require your seat to be at any certain angle. 
       It will strap to your body and use the belts to protect you."


Cheers

I do have my 2012 rule book but it isn't with me right now but unless something has changed, the SCTA does not require the use of a certified 38.1 device.  I believe it says it must be SFI 38.1-type thus why the DJ system is accepted.
