Abstract
Helmet positioning measurement system enabling the determination of the position in space of a helmet by measuring at least three distances (D1, D2, D3. . ) between at least three points located on the helmet (C1, C2, C3. . . ) and three corresponding points (S1, S2, S3. . .) located on the seat or the cabin, these said points being placed in such a way that it is possible to compute at least two position parameters .theta. and .alpha. with a great precision using the following univocal relations: EQU .theta.=f.sub..alpha. (D1, D2, D3, . . .) and .alpha.=f.sub..alpha. (D1, D2, D3, . . .) This system can be used in the aeronautical field, in the car racing field, during tests, where it is important to know the displacement of a human or mannequin head movement.
