Vario seat, sellette de pilotage.
"vario seat" is an harness of paraglider provided with a wood or
policarbonate plate of seat (like the
majority) but with the difference that the bands
are anchored under this plate. A
vario seat don't have main musketoons, and
the bands fix directly to under the
concept was applied to the first paraglides and had quite a lot of
success towards 1990, especially in the paraglides of the manufacturer "ITV International
Technique Voilerie" where all their
models (except the basic ones) brought.
is simple and intuitive: inclining the
weight towards ahead transfers the weight on the leading bands
and the wing speeds (the same as to apply the pedal of the classical
accelerator), applying the weight behind the wing takes incidence month
and him ralentitza, inducing
the weight in a side or the other one the wing tour towards that side.
The combination of this four movements in a well regulated chair to the
pilot and to the wing produces a very effective control about
the wing and a sensation of very soft and pleasant
If the chair is badly regulated, the wing not him much stable

strong, then the paraglide can be difficult to control, and have
problems like together to have the too much perforated wing or losses
to soak too much slow in the stopped position. This difficulty and the
fact that the paraglides with chair of pilotage had less gone out

It has rained quite a lot from 1992 in that the
champion Robbie Whitall won the worlds of
paraglide, precisely using a "Firebird Ninja"
provided with a vario seat.
From the Laboratory we believe that it is possible and interesting to
adapt vario seats again on some current up-to-date paraglides of class Standard, 1, ó 1-2,
and we are carrying research in this sense.
the position neuter, it is very easy to
transform the movement of the chair into the equivalent for the
accelerator. The rank among the position neuter and the maximum angle
of incidence the one that is necessary is to study with detail and to
put ribbons of limitation in mode
that does not leave the paraglide in stall. It is easy to adapt chairs of pilotage on paraglides of three bands and that of four, like the majority
of current paragliders.
