OK, I've been struggling to figure out the best way to allow my 1.5 and 4 year old to drive with me and my wife in my 1987 928S4. I have ordered some replacement 3-point belts and they are on the way. Once they arrive, then I can just use a booster seat with the 4 year old and the shoulder belt.

I also got a Cosco Scenera and a Radian 65SL. The Scenara for the 1.5 year old and the Radian for the 4 year old just in case it takes me a while to get around to following the instructions and doing that install on the 3-point belt.

I tried doing the install on both of these just using the lap belt and using the rear strap to secure the top. The problem I have is the bottom just seems really lose and has lots of play. I think this is just because of how high the seat belt retractor is at and the connection. I want to say I can pull up the bottom of both seats a good 4-5 inches, which I'm sure isn't good. I've even played with the locking clip and I think I have it about as secure as possible.

Has anyone else had any luck with these and is that just the best that can be done?

But my big question is about something else I've been considering. If the 928 just had the latch attachments in the back seat, then all this wouldn't be an issue. That would secure the base of both car seats and I'd be golden (other than the minimal leg room back that, but that's a whole other issue).

Since I'm going to be pulling out the rear seats anyway for when I need to get at the rear seat belt retractor to get to the 3-point belt installed, I was thinking of contacting a local welding business that I've had do work on other "projects" for me in the past and see if they could weld on some of the latch clips down in the crack of the rear seats. Then I wouldn't have to worry about the rear seat belt at all. I'll still add the 3-point for when they get older and need a booster or nothing at all.

I haven't talked to the welder yet, but don't think it would be too expensive. I hope it could be done. What does anyone think? Am I being stupid for some reason I can't think of? Or any other ideas? My 928 isn't exactly mint and for something that would be hidden by the seats anyway, I don't mind altering it if it makes things safer and can put my mind at ease to take the kids along.

Thanks in advance for any feedback!

I also have the Cosco Serena. I picked up a couple of the tether kits from my local auto parts store. I bolted the tethers to the shock mount bolts and wrapped the Latch restraints around the seat and fastened them to the anchors. I also put the seat belt through just to make sure I had my bases covered. It is held in pretty solid.

Someone posted in the past month a perfect fit seat. Search for it.

Yeah, I saw that list already and that is the one I have. But it is really loose at the base. It fits, but doesn't seem to be able to be tied in tightly. I even ordered those mounting brackets from that Australian website, but that seemed to address the rear strap, not the mounting for the lower one.

Cosmo, that is a pretty good idea, I'll have to check that out. Did you mount it to the shock bolts or just to the bolt that was mentioned in that other tread (the one where there is a hole there, but just needed a mounting bolt added)?

And do you remember where you found the tethering kit at? Which store? I'd like to see a pic too if you ever have a chance.

Thanks for the input though. That might be exactly what I'm looking for.

I fabbed some 'hooks' that went around the seatback pivot points and had LATCH connectability.
There are ways of making seat mounting work well in a 928. Keeping the mounting low is desirable although there are very handy mounts up high. I also used a high strap going back to the rear cargo lug.
I could probably dig out some pics or jog my memory if you take on a project.

Rear cargo loop is not a secure point to withstand impact.

Mike Simard

You can say anything is "not a secure point" or 'you're not supposed to do that" but it's meaningless if you otherwise do nothing and just use the lap belt.

I know the friggin cargo thing is not deemed a safety device but I have a resposibility to keep my child as safe as possible and not worry about unhelpful legalese comments like that. A moving car is not a secure thing to withstand impact!

The latch system down low is ideal. The problem is our cars don't come with that. The only reason I also tied into the top was because the seat I used seemed likely to rotate around the latch so I felt something up high was helpful. Using the stock lap belt alone is especially bad with a child because of the forward mounting of the belt. There's some room for increased safety. I can be pm'ed if anyone wants to know about what I've done for this.

Jadz928

It does have a place to mount a proper rear tether, which is more ideal that the rear cargo loops.

What I recommend is to use the intended chassis location right behind the rear seat, as outlined in this thread.



No need to get all pissy with me.

+10 for the passengers using the seats.

Jim, I remember reading that thread, but I don't remember it all. Save me some time. Did you ever resolve the hook positioning? I mean to say how it is horizontal in the picture. Wasn't it discussed that vertical would be much stronger?

Cosmo Kramer

I attached one to the factory one and two to the forward shock nuts. The left and right LATCH go onto the factory tether point and the far right shock bolt. The top tether goes on the left shock bolt. The anchors fit perfectly over the shock bolts.

The only thing that I could say is improper is that LATCH anchors are pretty much horizontal instead of facing down on an angle like factory LATCH anchor points (see pic 2). However the seat is in there very solid and I can't see it going anywhere in a crash.

I purchased the tether kits at a place up here called Canadian Tire, but you should be able to get them in the USA somewhere I am sure.

Bob,
I'm using the one from Australia. Hilton helped me get mine, but others are finding it possible to purchase.





Ted,
Nice work on the lower latch stuff! I'm passing the lab belt thru the front mount on the Radian65. This would rely on the lap belt to lock, during front impact. However, it does not inhibit twisting or rocking of the seat in motion.

robot808

Thanks Jim! Alright "others", where are you finding these?

captcashew

There is a link to the store in another thread. I ordered it a few days ago. The order was confirmed but I haven't heard anything since. I assume it is on the way. Go to this site:

http://www.kidsafewa.com.au/

And search for "BTX-0038"

My big issue wasn't the top attachment to the luggage hook or the new safety hook, but more from where I can secure the bottom of the car seat.

Cosmo and Mike, thanks, I'll look at the car and see if I can rig something up. I'll let you know if I have more questions (I'm sure I will). And thanks everyone for the feedback!
