Cage fondation

Ok so we bent up the fondation of my cage a couple of weeks ago.

Rear Hoop.

Center hoop or B-Hoop.

Front leggs, with dash bar.

Ok so first question is what program is useful to draw lines to similate cross bars? Second, this is a 2 door, I want some sort of triangulation on the B-hoop but I want to keep the back seat accessable for my twinns. Third, should I put a C hoop behind the back seat or just go with the ones I have? The goal is not to build a jungle gym but to add to the rigidity of the unibody and add saftey to us in the event of a roll off road.

Being that I just acquired a 2 door, I'm asking the same questions. Unfortunately... there are not a lot of options. I couldn't come up with any cross bracing at the B hoop that would not make it a MAJOR PITA to get in and out of (the back seat that is). You could do whatever you want at the C hoop (the one you skipped - behind the back seat)... but that's so far back, does it even count?

Unless somebody comes up with something I hadn't considered... I'm going to be skipping it altogether (until I chop the top - someday).

I agree. That would work for me, if I chopped the top, but not before. Nice try though Opie.

I have two ideas and would like to draw them up on the picture but I don't know how that is done. The only program I know how to use is paint and it sucks. What are you guys using to put info on your images?
 
To bad you don't live closer. We could put the old "mechanical engineering" mind to work, bend a few tubes and figure this thing out.

So you want to have access to the entire back seat, or if the center was somewhat unuseable that would be okay as long as a kid could sit on each side?

Also, any problem with tubes running behind their heads between backseat and back storage?

This is true. I may really consider that.
Maybe go diagonally one way behind the front seats and the other way behind the rear seat? :dunno:
I know the cross brace makes a big difference right there, but is it really necessary? You don't see too many wrangler's with them. Is that because the whole cage structure is shorter (horizontally)? Is the cross brace needed to protect the passengers or just the Jeep?

That is one of the ideas. Except add a perpendicular bar behind the driver. The other is corner braces that run from the top bar to a side bar.

I'm probably giong to run a hoop behind the back seat and it will have X's in it!
 
Why not put an x on just the drivers half of the b pillar, like this



or somthing like this



it got to help out a bit. kids can still get in the back, just through the passenger side, but you didnt really want to get out yourself to let people in the back did you?
 
Yea my seat was going to be irrelavent in tearms of gaining access to the back seat. That is also somethinng that was considered.

Hmmm... I would be very interested in hearing opinions on the effectiveness of this design.

These both look like they would do the job. Its better then nothing..

Just have the kids go in the back and climb over the seat lol.
That is what my da made me do.:roflmao:
 
What about something like this? I know it's a compromise, but....

Kyung's idea is closer to ideal. But if you are running 5 point harnesses you will run into a problem with the shoulder mount center point.
You should never have this point lower than a few inches from your actual shoulders, and it should be on a center line to your neck. Any off-set could result in neck injuries and even spinal injuries in a frontal impact situation.
I spent some time looking at my son's two door and decided if we were to cage it we would need to dump the back seats. I wish I was versed in some CAD program so I could show you what I'm thinking about....but I'm not too computer savey....:dunno:
Look at it like this. Your seat belt (5 point harness) shoulder mount(s) should be located right between your shoulder blades (behind the seat.)
Does that make any sence?

Do they make seats that, when properly mounted themselves, allow you to mount the shoulder harness to the back of the seat?
