Seat belt guide for TVR Griffith and Chimaera
Discussion
That looks like a good idea. The g/f gets immensely pissed off (oh, bless) with the belt cutting into her neck. Just wondering what difference this might make in a crash? Can't really see a much downside. It would probably be better at holding you down in your seat as there will be less play in the belt above your shoulder. I assume its mounting point is strong enough to take the forces generated in a crash, but if it failed it's only going to introduce a small amount of slack into the belt. Whether that would be a major problem I don't know?
I find a plain cheapy seatbelt pads (blank, non logo, bought in Tesco of all places) seem to do the trick for stopping the belt irritating the neck.
I agree that these look nice, but I would want to know what they would do the the event of a shunt.

On closer inspection, they look like guiders only, just to stop you (and passengers inparticular) messing about trying to get their seat belt on. Edited by JonRB on Friday 31st August 11:46
I don't think they would have any effect (either in a positive or negative way) in a smash.

Not totally convinced as they change the angle of the seat belt. In a shunt, I would predict that the belt will tension and try to form a straight line between the rear and tunnel mounts. That would put a sideways force on the guide which was never designed to take a seat belt load. This could result in guide being pulled out, resulting in a bit of loose metal tethered to the belt near to the shoulders and head... The way I see it ( which may be wrong) is in the event of an an accident you're flung forward which tends to straighten the belt against its mounting points.
If this gizmo is not in line with your shoulder (or wherever it runs over your body) and the hard point of the top mount, then you introduce a sideways force against the gizmo as it restrains the belt.
Now if it can stand the force generated then this is fine.
However if it was to suddenly break or bend then this introduces extra length and therefore slackness into the belt which means you can continue to accelerate into the steering wheel dash etc.
Just something to think about

Fair comment, but the amount of slack that would be produced would be minimal and the belt(for the holder to fail) would already be locked.If this gizmo is not in line with your shoulder (or wherever it runs over your body) and the hard point of the top mount, then you introduce a sideways force against the gizmo as it restrains the belt.
