It is if you don't want the to flip round and stab you should you have a rear ender. A lot of modern cars have tubes or similar welded into the frame for that reason.
The thought had crossed my mind.... I was just wondering how much hassle it would be...Foolishly, I forgot to have a look at the seat frames when I stripped the covers off...the passenger one would be straightforward as it's the open back type...not sure what goes on with the driver's though....will try to find some refurb pics, as this would be quite a good modification...
I believe all later seats have the built in tubes for the headrest, but I could be wrong. If not it's a bit of a job and the innards of the seat are a little flimsy.
I haven't but know somebody who did. It was a big job. Basically what he ended up doing was taking a 1983 BMW 3 series seats and using the back rest frame to build it up. Reason being that the type 2 seats were just too weak.
At some some past owner of my bus fitted the tubes to the bulkhead which would be great but i have lost the actual headrests
Thanks for the response Ladies....I was working on the premise that anything is better than nothing, but in this case, the hassle may not justify the rewards. It would definitely be a good 'standard' modification, offered by re-trimmers....suitable box section side to side and some tubing to brace the top rail to this cross-brace.... all sounds easy on paper
