A “winning argument for airline economics and passenger comfort”? – the airline stand up seat

29/08/2010 (Air Transport News)

For airline companies that would want to go for a "Stand-Up Cabin", Aviointeriors
of Latina, Italy is introducing a new class of seating, well below the present
classic high density seating and proposes a 23-inch pitch or less!

New materials, modern design and innovative use of technologies allow this manufacturer
to create seats with an increasingly smaller profile and unrivaled weight.

The "SkyRider", representing a completely new concept will premiere at the Long
Beach Aircraft Interiors Expo Americas 2010 from September 14th to 16th.

"It is a winning argument for airline economics and passenger comfort"; says
Dominique Menoud, Aviointeriors’ Director General who also confirms; there is
a strong interest for this new concept by airlines from around the world, including
from the USA."

Gaetano Perugini, Research and Development Director of Aviointeriors of Latina,
Italy, who developed and patented this new cabin concept adds; "The SkyRider’s
seat is the result of an in-depth ergonomic study where the passenger’s body assumes
a dynamic upright position, which is not only comfortable but also very healthy."

For airlines, this added cabin class offers the possibility of reduced ticket
prices in the low fare "SkyRider" section, maintaining sound profitability in
the regular economy, premium and/or business class, and allows to fill the aircraft
to the maximum certified passenger capacity.

The "SkyRider" occupant’s posture permits a comfortable overall longitudinal
space of 23 inches, or less with a partial overlapping between rows, compared
to conventional, high-density seating with 28" to 30" pitch.

The seat structure design itself also provides space for personal baggage. A
foldable shelf provides support for baggage without removing space for the passenger’s
feet. Hooks for coats and bags are provided in the aft top area of the backrest.

The seat structure, designed and engineered as a vertical truss to carry the
load at the height of the center of gravity to withstand horizontal overhang loads
applied and to transmit these to the floor attachments to satisfy the severe constraints,
is made of a TIG welded chrome-molybdenum steel tubes.

The lower structure, similar to a triangle having its top vertex very close to
the seat belt attachment with the corresponding legs straight to the base is stiffly
connected to the floor tracks. The two legs are loaded by a prevalently axial
stress, the front in compression, the rear in tension, exploiting material characteristics.
Since the free deflection lengths are conspicuous, to avoid configuration instability
under compression loads, chrome-molybdenum steel has been used.

The seat structure’s geometrical and material consideration, notwithstanding
a 23" or less pitch installation allows guaranteeing minimum exit passageway in
post-crash configuration.

For the dynamic 14g down test; the saddle-like seat bottom linked to two horizontal,
smaller diameter tubes contributes to absorb the vertical inertia load. For head
impact, a function of the head’s velocity at the impact time; the distance from
the TTOL position to the backrest surface is less than in a standard seat, resulting
in a lower HIC value. The backrest structure, made of a honeycomb core sandwich
panel with excellent absorption properties, held by a thin peripheral tube, further
contributes reducing the impact injuries.

Suitable certification plans for all commercial airplanes shall be agreed with
the airframe manufacturer and/or the STC applicant, addressing all the aspects
this novel design may require, is tested in Aviointeriors own certified dynamic
testing facilities.

The SkyRider’s limited bill of material; just a few parts, just simple and very
easy to be replaced parts, will make it very economical to operate.
