If you hit a pole in the center of the front of the vehicle it would have a lot more give as you weren't hitting the chassis rails head on where the overrider's where fitted, you would be bending a lot of other stuff like the crossmembers etc.
The triggers for airbags are very sensitive and need to be set off at exactly the right time to be effective.

Hi again and thanks .

I take from what your saying that unless in an impact you hit on the over riders and in turn the chassis rail the air bags will not fire at the correct time ?

If the case what point the airbags ?

Did the experts tell you how or why the bags fire ?

My undestanding is it is not the impact but the sudden slowing that sets this type of SRS off .

Not just the rail sensors but also the Airbag control unit must at the same time register .

A RR classic with srs that hits a Roo won`t have the AirBags deploy .

A Discovery 3 that hit a roo will .

I`m more interested in correct Information than who`s right or wrong or anything else and the written ( or typed ) word holds the emotion of the readed which may not mirror the writers .

I pressume from 90`s RR club and Experts that i`m rubbing the wrong way and the mirrors not reflecting well .

As said if you know of any documentation regarding RR classic SRS in particular , i`d like to read it or Discovery 1 or P38a as they are all very similar and even share many parts .

Cheers

Thats not what I said, the overrider's are to give a bit of softness if you hit the chassis rail head on, a very solid piece of the car which would otherwise cause the srs to deploy to soon or in a very small impact where it would be unnecessary, if you did not hit the chassis member head on, the rest of the car would deform, causing deceleration and then the airbags would deploy according to how the manufacturer set them.

If the case what point the airbags ?

See above

SRS sensors within the car. To stop you getting injured as much.

My understanding is it is not the impact but the sudden slowing that sets this type of SRS off .

Depends how the manufacturers set them. In the US, the setting compared to Europe for example are different due the the fact seatbelt wearing is not law in much of the US.

Not just the rail sensors but also the Airbag control unit must at the same time register .

Everything happens in milliseconds, so yes.

A RR classic with srs that hits a Roo won`t have the Airbags deploy .

Who says. How big is your Roo.

A Discovery 3 that hit a Roo will .

Again, how big is your Roo.

I`m more interested in correct Information than who`s right or wrong or anything else and the written ( or typed ) word holds the emotion of the readed which may not mirror the writers .

What are you trying to get at?

I presume from 90`s RR club and Experts that i`m rubbing the wrong way and the mirrors not reflecting well .

Call Rover Australia, they may be able to shed some more light on it.

Remember, me and many others on this site are just owners and enthusiasts who are giving their time to answer other people questions, some are more expert than others, I am just recalling conversations with people from the mid '90's on question similar to yours, SRS was fairly new back then so we were all interested.
While I understand the fundamentals of SRS, I am no expert on individual vehicles, all I know that the RRC was one of the first vehicles to come out with SRS on a full chassis vehicle (correct me anyone) and so the system had to be re-engineered, as a full chassis has very little give in certain areas compared to a monocoque car construction, hence, to give a little bit of give, my understanding is that, the overrider's (I also remembered on occasions being referred to as "crush cans") were fitted to compensate for the stiffness or solidness of the end of the chassis rail.

Just as an addition, any bull bar that was fitted to the RRC with SRS, had to comply with the system. The mounting points replaced the overrider's with collapsable mounts so the SRS system deployed correctly (someone like ARB may be able to confirm this)

G`day ,

i thought that you may have had some specific information on the RRC SRS that i could verify so as to be of more value but thanks anyway .

I have spent a fair bit of my time explaining this and you don't seem happy, what exactly do you want to know and why?

We have a RRC with srs the story goes because of the vehicle has srs a bar other than the factory bar cannot be used , because of the limited number there was never any testing ETC by ARB or any other here to comply any other bar than factory .

I have see expert type dealers selling SRS equiped RRC with ARB type bars which don`t have factory over rides so , i expect it is a grey area even though you say not .

What your telling me i don`t doubt you were told but it is little value to me because i can`t verify it .

What i have said comes from LR manuals and can be seen .

Obviously there is a fault with the way i explain myself .

Don`t use any more of your time on this please .
