air bags at airplane seats?

The popular press reports that three Boeing workers (or suppliers) were injured when airbags in the seats they were working on discharged.

Airbags in seats?

The A345 had airbags inside the seat belts of front row Y class seats. But Boeing?

A320's can also have the airbags in certain rows, they are attached to the seat belts.

CX have them built into the seat belts in business!

They are common on all types (Boeing, Airbus, Embraer, CRJs), mostly to meet FAA 16g seat rule for transport category aircraft (FAR Part 25) manufactured after October 2009.

They are usually for passenger seats facing the bulkhead, also for side-facing seats in business class, lay-flat seats, and also common on business jets.

They are also available as pilot/passenger seat retrofits on most GA aircraft (172s, Cirrus, Piper, Mooney, etc.)

AmSafe is the major supplier of these airbags:

The accident in question was indeed involving business class seats that were being worked on by the seat vendor.
Apparently the airbag somehow went off in the vendor employees face and he suffered fatal injuries. Two other people suffered minor injuries in the accident.
