It was split into two pieces. The lap belt was a conventional seatbelt you had to put on yourself, but the belt that went across your chest was connected to a motorized attachment that went around the window frame. I had them on my old Escort, and even if they didn't make much sense, they were kinda cool, in a gimmicky kinda way.

Oh, I voted for the Geo Metro. I'm certain they had a mildly sporty version which was fairly well regarded (I'm certain the Suzuki Swift had one so that's close enough).
