Abstract: An adjustment device of the position of a first part with respect to a second part, comprising an adjustment button mounted movable in translation inside a groove provided in the second part, and a blocking part having a locked position in which the blocking part prevents the first part from translating along the groove, and a locked position in which the blocking part enables the first part to translate along the groove, the adjustment button translating along the groove to move the blocking part to the unlocked position and to translate the first part along the groove.

Abstract: A clamping device has a body, at least one clamping member and an operating cover. The clamping member blocks at least one of the wire elements. The body has a cavity for passage a wire element and to house a clamping member, so that the clamping member is movable in the cavity along a first axis to a blocking position of the wire element. The operating cover is movable along the first axis relative to the body, and allows movement of the clamping member relative to the body along the first axis. The clamping device also has a drive device of the clamping member. The drive device enables free movement of the clamping member along the first axis with respect to the operating cover and with respect to the body, and enables movement of the clamping member away from the blocking position by actuation of the operating cover.

Abstract: A protection helmet includes a crown provided with a frontal part and an occipital part including an inner occipital part, a neckband having an inner surface designed to be in contact with a user's head, and articulation system configured to allow passage of the neckband from a use position to a storage position of the protection helmet. In the storage position, the neckband is folded into the occipital part of the crown so that the inner surface is facing the inner occipital part of the crown.

Abstract: A magnetic fastening buckle includes a first plug-in element provided with a first permanent magnet, and a second receiving element that includes a flat support plate surmounted by a support cap for a second permanent magnet. A pair of guiding pins protrudes on both sides of a first opening in which is inserted the first permanent magnet. The guiding pins are parallel to the longitudinal axis of the buckle, so as to ensure a self-entering effect of the first plug-in element in said longitudinal direction.

Abstract: A magnetic fastening buckle includes a first plug-in element (11) provided with a first permanent magnet (17), and a second receiving element (12) comprising a flat support plate (19) surmounted by a support cap (20) for a second permanent magnet (23). The body (13) of the first plug-in element (11) moreover comprises one pair of guiding pins (30) protruding on both sides of the first housing opening (18) of the first permanent magnet (17), both guiding pins (30) being parallel to the longitudinal axis XY of the buckle. The whole ensures a self-centering effect of the first plug-in element (11) in said longitudinal direction XY.
