Elements of discomfort - and the solution to the problem
Hopefully not too many seats look like this today - but IFE boxes do restrict leg room. Also the heavy aft beams are visible here, which can be lethal in a crash
The Problem – particularly on medium to long haul:
When we are tired we need to lie down, but we can't do this in Economy seats
Reclining the seat into the space of the passenger behind is anti-social
Pushing the hips forward to create a better angle of recline results in the spine being unsupported
The weight of the upper torso is suspended between the shoulder blades and the coccyx
The front of the seat pan presses into the back of the thigh, inhibiting blood supply
Contortion results in stress to the limbs
In some cases this can contribute to the onset of DVT
The Solution:
Elimination of conventional twin beams
Redesign of seat architecture within a fixed back shell
An articulating seat pan
An internal recline which fully supports the spine and lumbar region
Reduction of limb stress and the elements that can contribute to the onset of DVT
Greater knee room and access to under-seat space
Aft beam raised above knee level rather than at shin level
Exploiting the lumbar curve creates more knee room
Clever construction + inclined slide gives access to under seat space
Internal recline using patented inclined slide - 5" forward, 2.5" downward
Up to 45° recline fully supporting the back and aiding comfortable restorative sleep
5" extra leg room without physically increasing the seat pitch
