Abstract: There is provided a control stick module (10) comprising: a first shaft (100); a second shaft (110); a joint (140) connecting the first and second shafts; and a gimbal mechanism (120); wherein the joint is nested within the gimbal mechanism. The gimbal mechanism provides axes of rotation (201, 202) for the first shaft (100) and the joint provides axes of rotation (203, 204, 205) for the first shaft (100); and the axes of rotation (201, 202) provided by the gimbal mechanism intersect at a point corresponding to a point of intersection of the axes (203, 204, 205) provided by the joint.

Abstract: A control stick pivot (200) comprises a primary pivot bearing (210), a redundant pivot bearing (220), and a detection component for detecting malfunction of the primary pivot bearing. The redundant pivot bearing is provided on one side of the primary pivot bearing. The redundant pivot bearing becomes operative as a bearing in the event that the primary pivot bearing malfunctions. The detection component may comprise one or more features (230) provided on the redundant pivot bearing for applying a torque to the redundant pivot bearing during maintenance or testing and/or a sensor (300; 310; 320) configured to detect relative motion at an interface between the primary pivot bearing and the redundant pivot bearing.

Abstract: A damping assembly comprises a connecting rod for connection to a moving part to be damped, a damper comprising a piston, a mechanical fuse coupling the connecting rod to the damper, the mechanical fuse configured such that when a force between the connecting rod and damper reaches a threshold value the connecting rod becomes uncoupled from the piston. The damping assembly further comprises a biasing member that biases the piston towards a central position such that the connecting rod may be re-coupled to the piston.

Abstract: A bearing for guiding a first guided piece includes a first bearing surface with respect to a second bearing surface fixedly attached to a second guided piece. At least one first intermediate piece is interposed between the first bearing surface and the first guided piece and at least one first automatic release assembly for i) in a first assembly state, fixedly attaching the at least one first intermediate piece and the first guided piece for guidance forces which are lower than a triggering value, and ii) in a release state, permitting a relative displacement of the first guided piece with respect to the at least one first intermediate piece, at least in one displacement orientation, for guidance forces which are greater than the triggering value of the first assembly.

Abstract: A gear arrangement comprising a gear train having a first gear on a first axle and a second gear on a second axle, the first and second gears arranged to intermesh, characterised in that the gear arrangement is provided with a friction drive comprising a first rotary element mounted on the first axle arranged to frictionally drive a second rotary element mounted on the second axle.

Abstract: A bearing for guiding a first guided piece (11; 12) includes a first bearing surface with respect to a second bearing surface fixedly attached to a second guided piece (30; 16). At least one first intermediate piece (28; 18) is interposed between the first bearing surface and the first guided piece and at least one first automatic release assembly (34, 35, 36; 44, 45, 46; 24, 25, 26) is adapted for: in a first assembly state, fixedly attaching the first intermediate piece and the first guided piece for guidance forces which are lower than a triggering value; in a release state, permitting a relative displacement of the first guided piece with respect to the first intermediate piece, at least in one displacement orientation, for guidance forces which are greater than the triggering value of the first assembly. Application to a shock absorber or to a cylinder in particular.
