Seat Cover Technology

When installing new car seat covers, I noticed they were asymmetrical and specified which side should be near the window with the label "airbag". Is there some design feature in the seat cover construction to specifically make it safe for use with side airbags? Or is it coincidental with the fact that the window side is the user approach side and will get more wear? Is there an ISO standard? I noticed similar airbag tag on a different brand seat cover installed on another car. If I install on an old car without side airbags, that should be safe from any side airbag incompatibility issues with the seat cover, right?

New and old

When 2 city names use the same base origin, one is usually named New Something. Districts are usually unofficially called Old Something and the name eventually sticks from common usage. In Chinese, one American city was unofficially called Old Gold Mountain (舊金山) and eventually became the official Chinese name used in China for this American city. 舊金山 is used in most archived/indexed web content, official documents, and online translator dictionaries. That city is of course San Francisco. Online translators also recognize Francisco to mean San Francisco.
