CageyH Posted February 18, 2019 Posted February 18, 2019 I currently have the horrid looking Caterham Branded CE approved 4 point harnesses in my car, which has carbon Tillets. Having just secured a Volvo booster seat for my three and a half year old passenger, I am seriously thinking about fitting inertia seat belts.Do they fit with Tillets, and is there any way I can also fit a proper quick release 4 point harness at the same time. I believe it will be difficult, as there is not much room in the side of the tillet for a harness and the seat belt receptacle.I think that the inertia belts will be safer for use with the booster seat, and as I am not going to track the car, then surely they will be good enough for road use by me as well?
Area Representative Golf Juliet Tango Posted February 19, 2019 Area Representative Posted February 19, 2019 Hi KevI can try it out for you. I have a Tillet in the Seven and some new inertia reel belts waiting to be installed in the 21. I need to visit the 21 within a couple of days so can collect one of them then.
Tazio Posted February 19, 2019 Posted February 19, 2019 On standard leather seats with inertias and driving with no doors, I went round a left hander that tightened up, car hung on, I ended up with most of my upper body hanging out the car.... harness all day long for me..
elie boone Posted February 20, 2019 Posted February 20, 2019 Only if the booster seat sits higher than the Tillet will it work with inertia seat belts, if you are able to find an inertia seat belt with a webbed fixed side it would be better but most have a stiff steel cable. With a soft fixed side you can feed this trough the Tillet and also feed the other lap belt trough the Tlllet that would work but then if you would like to use the harness the metal clip of the inertia belt would be in the way as it would stay inside of the Tlllet.
Area Representative Golf Juliet Tango Posted February 20, 2019 Area Representative Posted February 20, 2019 Elie is right. The stiff steel arm holding the socket part of the buckle won't fit next to a Tillet.On the set I have the arm is about 200mm long overall. On my Seven when a Tillet is shoved right back, the socket would poke through the seat-belt aperture but the seat is so tight to the transmission tunnel that the steel won't go through.
anthony1956 Posted February 20, 2019 Posted February 20, 2019 3 point kind of chills me; years ago I recall stopping suddenly at low speed (car park or some such), without straps done up and I was amazed (edit: horrified) how my body went forward. There isn't much space in there and it has always chilled me the thought of how with a three point I would be twisted forwards, which in a normal size tintop means nothing as there is a lot of space (and airbags) ; not so in a Seven - S3, I suppose SV may be different.
CageyH Posted February 21, 2019 Author Posted February 21, 2019 Thanks chaps.It was from a safety point of view that a booster seat designed for a three point belt would be better than an ill fitting 4 point harness. Now I know that they won’t fit, I will just have to adjust the harness properly.
anthony1956 Posted February 21, 2019 Posted February 21, 2019 I thought that was an interesting question because it caused me to explore child seats and they all seem to be 4 and five point harnesses. I seem to recall our 4/5/6 point harnesses technically, are not legal. Strikes me there's a bit of an irony at work - perhaps explains the "blind eye" approach.
CageyH Posted February 21, 2019 Author Posted February 21, 2019 My harnesses are CE marked, so they should be legal with a CE marked car seat.
anthony1956 Posted February 21, 2019 Posted February 21, 2019 never thought about that. I imagine they all are.
CageyH Posted February 21, 2019 Author Posted February 21, 2019 Is France leaving the EU? Most of the harnesses I would like to use are FIA approved. EU regulations require you to be able to do them up with one hand, hence the nasty looking CE approved harnesses.
CageyH Posted February 22, 2019 Author Posted February 22, 2019 I have seen that there are inertia belts with a longer stalk. If the stalk positions the belt receptacle above the side of the Tillet, then it could work?
elie boone Posted February 22, 2019 Posted February 22, 2019 It looks like Securon might help you. http://www.securon.co.uk/seat_belt_harness_tech_specs.htm but there are 4 point harnesses that are E marked with a push button instead of a turn buckle.
CageyH Posted February 22, 2019 Author Posted February 22, 2019 That is the style of harness that I have fitted. The question was more about if that would work with well a child seat.
elie boone Posted February 22, 2019 Posted February 22, 2019 Yes but your harness has the lap and shoulder belt are 1 piece ? it would work for the lap belt if the booster seat is high enough and if you could make something that would bring the shoulder straps closer together
CageyH Posted June 5, 2019 Author Posted June 5, 2019 Anybody know a manufacturer that makes add on sternum straps for harnesses?I have a strap I am using right now, but I am not sure how well it would work in an accident.
