It rips out through the side of the seat around the shoulder area.
Remember, air bag deployment is only supposed to happen in
life-threatening events, so damage to the seats, dash, steering wheel,
etc. is a secondary consideration.

Yes, I checked my seat backs - there's a tag that says SRS Airbag along the
outside edge and the seam is sewn, so if the bag deployed it would certainly
rip and maybe destroy the upholstery. Anyway, seems like we're not certain
about the safety of seat covers at this point (?)

Agreed, and I suspected this is what happens.
I was wondering if here was perhaps some sort of mechanism in the air bag
assembly to aid in 'busting through' this apparently solidly stitched seat
cover, or if it simply relied on sheer explosive power to rip through.
Maybe there is a cutting edge that helps start the ripping apart. That
would certainly reduce the magnitude of the explosive power required to
deploy the air bag.
What I am getting at is - if it were just relying on explosive power only
then adding a regular seat cover would add an extra 'membrane' layer the
bag would have to bust through.

That seems highly unlikely, as anything sharp would be a potential
hazard, even with a side airbag.

That's exactly the issue. The stitching and material strength in the
side of the seat is most certainly carefully calibrated to the power of
the airbag. That wouldn't be true of a seat cover. The only safe course
of action is to not cover the area from which the airbag deploys.

Your seat covers are made to come apart in the event of a deployment.
They’ve got a failure point designed into the cover. It’s not
dissimilar to steering wheel or dash air bags. The trim is
constructed to split open in a certain way.

Thanks - this is the explanation I was looking for - designed-in failure
point / line.
