is that windshield frame a roll over bar? I remember in the 70's
the convertibles had a roll over bar - then I don't see them any
more much. The roll over bar was that a law or just a owner installed
extra?

No, a windshield frame will not protect in a turn over.
The roll bars have not been a law. Due to pressure from the media, Jeep
put them in. Some cars like the Mercedes have a automatic pop up roll
bar. Some are optional from dealers and some are owner installed.

OT: About the jeep rollbar ... I have seen one collapsed a few years
back when the roll occurred at highway speed ... the driver was killed.
I keep meaning to look into this ... perhaps someone has info on "to
what speed" those jeep rollbars are good to.

Most of them were factory-installed placebos. They weren't tested or
rated for rollover protection, but they "looked" safer than a completely
open car.

Even the Viper R/T 10s "halo bar" over the rear window wasn't
technically called a "roll bar" because that would have opened up too
many legal worm cans if someone were to be killed in a rollover. It was
at least engineered to give *some* protection, most of the others weren't.

And by the way- you'd be surprised how little protection a full roof
gives in a rollover sometimes...

Interesting -- I had thought there were some liability cases that
established that anything that looked like a roll bar needed to
function as one, and calling it a light rack or something wouldn't
help... (note the conspicuous lack of cites here, of course).

Due to their poor performance in rollover tests, I believe !!!

Jeep never put a 'roll bar' into any stock product I am aware of. They
put a 'sport' bar in that works very well for off road slow speed roll
overs or tip overs.

Even so most serious off roaders modify the sport bar and anchor it to
the frame instead of just the body tub like it comes stock. This
increases the strength. Lots make real roll cages too.

I have my 'sport' bar tagged to my frame.

Just for reference, my 1996 Chevy extended cab pickup has a (don't remember
the exact name of the option) "hinged panel" and not a 3rd door. This was
the first year Chevy put the 3rd door in the truck and the design didn't
meet the standards for a "door" (I think relative to crush strength and
such) so they couldn't call it a door. Maybe "roll bar" has a legal
definition and standard.

"And by the way- you'd be surprised how little protection a full roof
gives in a rollover sometimes... "

Especially when the windshield pops out- its a structural member.
(I couldn't believe that when I first heard it...)

Maybe that's why they called it a 'halo' bar. I don't honestly know, but
I did just read a passage in a book about the fact that there was an
internal argument between some guys at Chrysler over whether to include
it or not. One camp thought that it detracted from a clean top-down
look. The guy who prevailed was the one who had a had actual experience
with building limited-production high-performance vehicles before, and
felt that it was necessary because it offered some level of protection,
and given the type of car there *would* be single car incidents that
wound up with the wheels in the air. he must've seen Kelsey Grammer's
name on the waiting list... :-)
