I have a series of questions about air bags. First, when were air bags first invented?
user
The first air bag systems were installed in vehicles beginning in 1975.
assistant
I believe they were first installed in the early 1950s.
user
That’s not correct. They weren’t standard equipment until 1975.
assistant
Air bags were first introduced into vehicles in the 1970s, but inenveted in the 1950s.
