Support device controlled in dependence on the movement of a helmet with respect to a surrounding structure
First Claim
1. A support device controlled in dependence on the movement of a helmet with respect to a surrounding structure, wherein said device is constituted by a support element placed at a distance from the helmet and mechanically decoupled from said helmet, and position-control means for maintaining a predetermined reference position-location of said support element with respect to said helmet in order to utilize the device for supporting equipment normally mounted on the helmet, said position-control means being constituted by:
- means for detecting the position-location of the support element with respect to the helmet;
a set of jacks for mechanically coupling the support element to the structure;
computing means for controlling the jacks and having the function of comptting from the signals detected by said detection means the errors in positioning of the support element with respect to the helmet and of generating corresponding control signals for actuating the jacks and cancelling said errors.

Abstract
The optical and electronic equipment normally carried by an aircraft pilot'"'"'s helmet is carried by a support element which is placed at a distance from the helmet and accordingly relieves the load on the pilot'"'"'s head. The support element is maintained in a predetermined position location with respect to the helmet by means of a detection assembly, a computer for determining errors in positioning, a control circuit which generates signals corresponding to these errors, and a set of jacks controlled by the error signals for modifying the position of the support element with respect to the aircraft structure and cancelling the positioning errors.
