Hi Melvin
No relation to wheelchair or car but I wonder if the addition of the seat belt with the AutoChair hoist is a newish thing as I have that on my 80Kg hoist and the installer told me it was a new thing?
Just a warning about having the “hoist bar pressing down on the chair” as I was doing that to help cut down on rattles but unbeknown to me at the time and until it was too late the hoist bar pushed down on the back of the captains chair and the captains chair in turn pushed down onto the battery gauge of my scooter pushing the gauge into the scooters tiller housing. Might not effect you but something to watch out for.
