Abstract

The invention relates to a helmet comprising at least one movable visor and a shell to protect the head of the wearer, characterized in that the visor is attached to a support connected to the outer surface of the shell by a rotary mechanism making it possible to move the visor around the shell, the rotary mechanism consisting of a single mechanical connection positioned substantially at the top of the shell.

The invention is designed particularly for the military aviation field and also applies to helmets comprising several visors.

Claims

1. Helmet comprising at least one movable visor and a shell to protect the head of the wearer, wherein the visor is attached to a support connected to the outer surface of the shell by a rotary mechanism making it possible to move the visor around the shell, the rotary mechanism consisting of a single mechanical connection positioned substantially at the top of the shell.

2. Helmet according to claim 1, wherein the rotary mechanism is designed so that its axis of rotation passes through a point substantially positioned in the centre of the shell and the said axis is also offset at an angle relative to the vertical axis passing through the same point.

3. Helmet according to claim 2, wherein the rotary mechanism makes it possible to move the support of the visor between two positions, a first position of use of the visor for which the visor is positioned at the front face of the helmet and a second position for stowing the visor for which the visor is positioned at the rear of the helmet

4. Helmet according to claim 3, wherein in order to move the visor between the position of use and the position of stowage, the visor moves along the lateral portions of the helmet.

5. Helmet according to claim 4, wherein the visor is moved in a rotary movement through approximately 180°

.

6. Helmet according to claim 5, comprising a mechanical means for protecting the visor when the said visor is in the stowage position.

7. Helmet according to claim 2, wherein the said angle of offset is approximately 30°

.

8. Helmet according to claim 1, the support of the visor is also a means for gripping the visor and for moving the said visor.

9. Helmet according to claim 8, comprising at least one mechanical branch connecting the visor to the rotary mechanism.

10. Helmet according to claim 9, wherein the support of the visor consists of a central mechanical branch connected to the centre of the top longitudinal portion of the visor and of two lateral mechanical branches connected to the lateral portions of the top longitudinal portion of the visor.

11. Helmet according to claim 5 comprising a mean for holding the support of the visor in the first and in the second position.
