retro fitting safety stuff

[omega]

been thinking of getting some new seat belts of the chap here who makes them and started thinking of seat belt tensioners.now theres some on a omega in the scrap yard that look like they just bolt on to the side of the chair,so are they this easy to fit or am i missing something?

Wouldn't seat belt pretensioners have to be connected to an ecu so that they fire at the right time in an accident?

I think the stuff from 90's vauxhalls was purely mechanical - no ECU to trigger them, it was sudden shocks that set off the mechanism.

Whilst I would be happy to add normal seatbelts to an older car (and have done so in the past) I wouldn't even vaguely consider messing around with tensioners. There is a lot of science goes into seat belt angles and tension, and being slightly misinformed about their operation or not getting mountings quite right could have very bad consequences.

I wouldn't do it. A cars suplementary restraint system takes huge amounts of money and time to develop. If you were to get your angles or positioning wrong you could cause injury rather than prevent it. Also the frame of your car is not designed for them and may not be strong enough.

Just stick a big spike in the centre of your steering wheel that in my opinion would save more lives than any modern safety system if everyone had that they would drive more carefully.

I would consider using a mechanical pre-tensioner system provided I was using it together with the original seat and belt with the same layout as the original design. I definitely wouldn't mix and match pre-tensioners, belts and seats.
