But this one also has a unique "space-sharing" feature which effectively creates an "arm well" of overlap between adjacent seats. It is an interesting concept which ultimately can see the seats pitched at 28" in the cabin while still providing a 75-78" bed.
It is an interesting tweak to increase cabin density.
Link goes to my story about the patent with additional details included.
A tweak to increase business class cabin density in particular because the airline wants more business class seats per flight to sell to the higher proportion of leisure/hybrid travelers (to business travelers) in the long-haul international business class cabins?
