Abstract: The invention relates to a light diffuser casing comprising an enclosure defining a cavity and provided with a closable opening configured to enable a headlamp to be inserted inside the casing. A light diffuser is arranged in the casing to receive a light beam coming from the headlamp and to make said beam diffuse on the enclosure. The light diffuser is made from a translucent or transparent material so that said beam passes through it, and the enclosure is made from a translucent material. The invention also relates to a method for using the casing.

Abstract: A safety helmet has a protective shell, an inner liner with several attachment branches, and at least a first securing clip to fit an accessory on the outer surface of the shell. Each attachment branch of the liner comprises a fixing part inserted and blocked in a slide of the shell by said first securing clip which acts both as latch to attach the liner to the shell and as female loop for clipping of a second securing clip connected to a chinstrap.

Abstract: A safety helmet comprising an outer shell, an internal headband composed of a neckband at the rear and a securing strap at the front, and an adjustment mechanism of the headband. The adjustment mechanism comprises a double cog-wheel having a first sprocket associated with a first drive rack of the neckband, and a second sprocket associated with a second drive rack of the strap. The two sprockets have different diameters to perform differential driving of the strap and of the neckband.

Abstract: The securing device, to be mounted on a ski-board, includes a main body with a support base for a sole, two lateral flanges, and an assembly for the attachment of the shoe to the main body, including: a protective element and first and second means for attaching the latter onto the first and the second flanges. The first means include two serrated straps, namely front and rear. The proximal end of at least one strap is mounted so that it pivots on the first flange. The distal ends mate with front and rear locking systems fixed onto the protective element, for adjusting the length of said straps. The second flange is fitted with front and rear attachment systems. The second means of attachment include a fixing handle, pierced with two holes, in which the attachment systems engage, and a closure system by which the handle is connected to the protective element.

Abstract: A protective helmet is composed of an external crown made from plastic material, and a semi-rigid neckband adjustable by adjustment means. At least one end of the neckband is joined to the crown by a sliding mechanical link comprising position indexing means controlled from a slide able to be moved from the outside in a slit of the crown. The indexing means are formed by a rack molded directly along with the crown.

Abstract: A carabiner includes a fixed C-shaped body equipped with a securing part, and a gate movable around a pivoting axis between a closed position and an open position. The gate includes a latching part and a locking ring fitted coaxially around the gate. An end head of the gate partially surrounds the securing part in the closed position, and includes a shoulder acting as end-of-travel stop for the ring in the locked position.

Abstract: A protective helmet is composed of an external crown made from plastic material, and a semi-rigid neckband adjustable by adjustment means. To ensure that the helmet is efficiently secured on the user's head regardless of his or her hair-style, the neckband is in the shape of an Omega composed of lateral securing zones and a curved central part for free passage of the user's hair worn in a pony tail. The ends of the lateral securing zones of the neckband are joined to the adjustment means.
