Does anyone have any information related to lie-flat seats (e.g., first class sleeper seats) arranged in a herringbone fashion, which were developed or in use prior to 2002? I’m conducting research related to the development of these seats and am looking for any information I might be able to get a hold of.
If possible, I’m looking for information related to a herringbone seat(s) that has extra room or a space around the headrest, which is usable to the passenger when the seat is in the reclined (i.e., lie-flat) position. Currently, I know of several herringbone seats developed or in use during the 90’s or early 2000’s (e.g., the British Airways first class seat shown here - http://www.google.com/patents?id=flw...4vYMajl0gG4zPGpAw&ved=0CDgQ6wEwAA; and Virgin Atlantic’s upper class seat shown here - http://www.google.com/patents?id=MLC...ymH6nB0QHwvYjrAw&ved=0CDYQ6wEwAA).
Any information about other seats of this type would be much appreciated.
