1. A support assembly for a helicopter control stick, the assembly comprising a supporting structure and an instrument panel fixed to each other;
- and connecting means for connecting said stick to said supporting structure;
said connecting means comprising;
an arm elongated in a longitudinal direction and having one end for supporting said stick;
guide means for connecting said arm in longitudinally sliding manner to said supporting structure, to move said end to/from said supporting structure; and
rotation means for connecting said arm to said supporting structure in rotary manner about a horizontal axis, to adjust the height of said end;
said assembly further comprising;
first releasable retaining means operated manually to lock rotation of said arm with respect to said supporting structure in a desired angular position; and
second releasable retaining means operated manually to lock at least longitudinal translation of said arm with respect to said supporting structure in a desired longitudinal position;
said first and second releasable retaining means being independent of each other so that, when said second releasable retaining means are released to permit longitudinal translation of said arm, the angle of the arm about said horizontal axis is still locked by said first releasable retaining means and remains unchanged;
said horizontal axis extending transversely between the longitudinal ends of said arm.

Abstract
A support assembly for helicopter control sticks has a supporting structure; an instrument panel fixed to the supporting structure; and a connecting device for connecting the sticks to the supporting structure. The connecting device has a longitudinally elongated arm fitted on one end with the sticks; and the arm slides to move the sticks to/from the supporting structure, and rotates about a horizontal axis to adjust the height of the sticks.

8. A support assembly for a helicopter control stick, the support assembly comprising:
-
a supporting structure; an instrument panel fixed to said supporting structure; and a connecting assembly, wherein said connecting assembly connects said stick to said supporting structure;
said connecting assembly comprising;an arm elongated in a longitudinal direction and having one end for supporting said stick; a guide, wherein said guide connects said arm in longitudinally sliding manner to said supporting structure, to move said end to and from said supporting structure; and a rotary assembly for connecting said arm to said supporting structure in rotary manner about a horizontal axis, to adjust a height of said end; a first releasable retainer operates to lock rotation of said arm with respect to said supporting structure in a desired angular position; a second releasable retainer operates to lock at least longitudinal translation of said arm with respect to said supporting structure in a desired longitudinal position; wherein said first and second releasable retainers are independent of each other so that, when said second releasable retainer is released to permit longitudinal translation of said arm, the angle of the arm about said horizontal axis is still locked by said first releasable retainer and remains unchanged; wherein said horizontal axis extends transversely between the longitudinal ends of said arm.
