Mechanically Adjustable Lumbar Support In Y Seats

I was wondering, is there any reason why mechanically adjustable lumbar support in Y seats never really caught on? It was somewhat of a trend in the late 1990s and early 2000s on some long-haul aircraft, however, this feature apparently has seemed to die out, especially with the trend towards slimline seats where such feature is impossible to fit inside the seat.

For example, the Weber 5150 seats in DL's 772ERs have mechanically adjustable lumbar support in Y, while the Weber 5751 slimline seats on the 772LRs do not. Also, US Airways' A333s have adjustable lumbar support in Y, while the newer A332s do not (they don't even have winged headrests).

Maybe it is just an added maintenance issue or weight...?

Not sure about that though... would be interesting if someone can confirm/deny

It's a useless gimmick that adds complexity and increases maintenance costs. Passengers aren't willing to pay more for such things.

The same could be argued for winged headrests. I don't think this is much of a deciding factor for most people. Still, DL's long term goal is to have winged headrests in Y on all international aircraft. The Weber 5751 slimline seats that DL's 763ERs will be getting will probably have winged headrests.

In the early 70s, TWA advertised inflatable lumbar supports throughout their fleet - even the 727s and Convair 880s had them, along with the then top-of-the-line 747s and L1011s. There was a button on the armrest. When depressed, it opened a valve. If the passenger leaned forward, the support would inflate. If he leaned back, it would deflate until the button was released.

According to f/a's, they were fun for awhile, but ended up being a maintenance issue, which may be why they didn't last past the late 70s. I think AA and EA featured them in widebodies as well.

On my very first 747 trip on TW in July of 1970, all the seats had those inflatable lumbar supports.
They worked pretty good. I have the same type of system in my Mazda Tribute.

While that may be true, they sure can make a different in neck support. Especially with airlines removing pillows now.

Winged head rests are great. They make it easy to sleep sitting in the seat with no need for a pillow.
