Well, replaced seat this morning. Noticed beneath upholstery
some sensors (??), and 3 connectors under seat (only 1 wire
from seat itself; all 3 lead to front of auto). All it took
was to disconnect wires, removed seat track, then seat itself.
I could then have just replaced the upholstery (which is just
hooked on, not sewn), but opted to replace entire cushion.
And, hey, airbag didn't pop. Cost me 1/2hr of my time, rather
than the $175 Hyundai wanted

Thanks again to those who responded to original post
