Investigators continue to piece together the cause of the accident involving Asiana Airlines Flight 214, which crashed just short of a bay-adjacent runway at San Francisco International Airport on July 6th. In addition to two fatalities, there were over 150 passenger and crewmember injuries linked to the crash, and a pattern seems to be emerging when it comes to the cause of some of those injuries.
According to the Wall Street Journal, “[w]hen passengers began streaming into emergency rooms, hospital staffers said they saw many injuries associated with using seat belts that fasten around the lap,” the kinds of in-seat restraints that are used by the vast majority of airlines in all seating areas of their passenger aircraft.
WSJ notes that the design of these restraints — notably the absence of any chest or shoulder harness — is a practical one: “Seats where lap belts are used are now designed so that in a crash, passengers are cushioned by the seats in front of them. The seat back is designed to fall forward, absorbing the blow. [Installation of chest harnesses] would add to seats’ weight and require a heavier mounting system and floor frame, experts said.”
Over at CNBC, they’re opining that the absence of a safer seat belt system on planes comes down to questions of cost and comfort.
