Rear Hand Hold Suggestions?
 

On occasion I ferry my mum about town. When wife is in car as well mum insists on sitting in the back. Her only dislike is there is nothing to hang on to if I corner faster than she is used to. (This doesn't have to be very fast.) Are there any suggestions for fitting some sort of hand hold?
Thanks.

I say just lock the seatbelt.

Thanks but
1/ We're not going racing.
2/ Mum is 80+ and probably wouldn't be able to breathe.
3/ It would probably be beyond her.

Well i didn't mean it in a racing manner. But locking the seatbelt. At least in my mind would hold her in place. Does well for my siblings car seats.
