Description

REMOVABLE MODULAR LINING FOR SAFETY HELMETS}

The present invention relates to a modular lining for a helmet for use in helmets, such as motorcycles, bicycles, skis, other sports and the like. In particular, it relates to a removable modular lining.

As is known, one of the important elements of a helmet whose structure has an important effect in manufacturing and using the helmet is lining.

As a rule, the lining is attached directly onto the inner surface or core of a well-formed helmet made mostly of foam material such as high-density polystyrene or made of a material with high energy absorption capability which gives some discomfort when in contact with the user's head. .

Thus, the lining provides a first function of protecting the helmet from other functions, ie scratches, breaks, and accidental wear, and a slight sweating action, which is difficult to obtain in other ways, while providing a comfortable feeling in contact with the user's head. has a second function of ductility and sponge properties to allow perspiration.

Nevertheless, linings include defects, that is, difficulties in mounting and finishing due to difficulties in placing the linings on the helmet, and wear and hygiene problems that require replacement due to physical properties. There is no flaw.

In fact, the helmet core is in the shape of a spherical cap. In order to selectively place and secure the lining on the helmet, it is ideal to manufacture a lining along a substantially hemispherical surface, which is clearly not easy and economical. Thus, the lining is generally divided into two elements: an annular band circumferentially located along the equator of the hemispherical cap and a disk-shaped surface attached on the pole of the cap. Thus, each of these two elements, which do not need to line the entire hemispherical surface, can be properly obtained with a flat material even though the adjustment on the spherical surface may include some irregularities or cause some folding. In general, the annular band is widely attached, partially overlapping the disk element which is simply placed on the pole of the cap after covering several points with the adhesive.

In any case, the arrangement of the elements is always slightly uncertain and does not provide a fine finishing effect.

In inexpensive helmets, the disc elements often do not adhere and thus tend to separate from the partially overlapping annular bands and fall off the helmet.

It should be appreciated that the material forming the lining has a significant impact on sweating ability, helmet comfort, and longevity. Materials that are superior in comfort may not be optimal in wear, and therefore may have to be discarded when their lifetime is not long enough, and therefore an appropriate compromise must be found.

Finally, the hygiene aspects of the lining should also be emphasized. It is evident that the lining tends to be irreversibly damaged by use, especially in dusty environments or in hot seasons. At present, there is no useful way to face this problem. Motorcycle riders often wear knit caps under helmets that address hygiene issues in addition to other functions because they can be easily cleaned, but not all riders prefer to wear caps under helmets. .

The object of the present invention is to solve the above-mentioned drawbacks. In particular, the present invention can be effectively partitioned into elements so that they can be perfectly attached to the hemispherical surface of the helmet core and are easy to allow for cleaning or replacement whenever required without having to find any compromises in selecting the quality of the material. To provide a removable and reapplicable helmet lining.

This object is achieved with a removable modular lining for the helmet described in the claims below.

Other features and advantages of the helmet according to the present invention will become apparent from the following detailed description through examples shown on the accompanying drawings.

As shown in Fig. 1, the helmet 1 is impacted with the outer shell 1a, which is generally made of a plastic material such as polyester, polycarbonate or a synthetic material such as glass fiber, kevlar fiber or carbon base material. In the manner known as the inner surface or core 1b, which dissipates energy and can be, for example, a core of a high density foam material.

On the periphery of the core 1b, a narrow strip extending into the spherical cap of the helmet substantially parallel to the first layer of the fixing lining covering the outer edge 2a of the core, ie the part not in contact with the user's head, or The band 2b is attached.

The first stationary lining may be made on a different predetermined thickness of fibers attached to the helmet core 1b by any conventional manner (eg, gluing, etc.) and mixed with the auxiliary material.

According to the present invention, a first coupling means 3a is provided on the peripheral band 2b of the fixed lining for attaching a removable lining, and on the surface of the helmet core 1b a second coupling means 3b is provided. Is provided. Advantageously, the coupling means 3a, 3b may be Velcro in the form of small squares or in the form of discs, which are attached to the stationary lining and the helmet core, respectively.

As shown in Figs. 2a and b, the modular lining according to the present invention comprises three separate modules or elements, namely a first central element 4 (Fig. 2a) and a helmet (as shown symmetrically in Fig. 3). It consists of two symmetrical side elements 5 attached to 1) (FIG. 2B shows only one of the elements 5).

2a shows in detail a central T-shaped center element 4 comprising a center band 4a and two end bands 4b. Once attached on the helmet 1b, the center band 4a extends along the axis of symmetry between the two helmet lobes, and the two end bands 4b are semicircular close to the edge 2a of the core 1b. And are joined together at two radially opposite points. The center band 4a is fixed to the second coupling means 3b and the two end bands 4b are fixed to the first coupling means 3a so that the central element 4 is fixed.

Preferably, the middle part of the band 4a comprises a wide shaped disk 4c for more firmly attaching the central element 4 on the helmet core 1b. The disc 4c may act as a support for any label or may have a finishing function.

2b shows in detail one of the side elements 5. Each of the elements has a substantially elliptical shape and includes four V-shaped notches 5a formed along the side facing the pole of the helmet when in use, the apex of the V-shaped notch 5b being the side element 5. Goes into the elliptical shape. The notch 5a forms five tongues 5b of different widths, and this configuration is optimal, with no folds, because it is particularly suitable for obtaining the correct placement of the lining onto the inner curved surface of the helmet core 1b. Can provide a finish. In fact, as shown in FIG. 3, two side elements 5 are located correspondingly to the two side lobes of the helmet and are removably fixed to the second engagement means 3b.

Alternatively, the side elements 5 can be attached by means of adhesion, in which case only the central element 4, ie the lining portions that are more susceptible to fouling, is removable.

Preferably, the central element 4 is substantially attached to the two side elements 5 such that the end band 4b and the center band 4a can partially overlap with the edges of the two side elements 5. Pressure can be applied and accidental separation can be prevented.

Removable linings are made from fibers of different thicknesses mixed with auxiliary materials, and preferably the inward facing surfaces of the removable linings are designed to provide optimal placement for small square or disc shaped Velcros 3a and 3b. Is prepared from.

By providing the user with lining elements 4, 5 of different thickness, the helmet can be used more flexibly, especially for young and fast-growing users.

The modular lining according to the present invention can achieve its intended purpose perfectly. In fact, the specific shape of the three elements allows for easy and accurate placement in the helmet without causing folding or other bumps in positioning the elements despite having to adhere to the substantially hemispherical surface. Thereafter, the same element is firmly fixed to the helmet core, so that it is not required and troublesome separation does not occur. Finally, for the benefits of quality and hygiene of the material, which can now be selected independently of the requirements of durability, the removal, which can be achieved by simply pulling the lining element, in particular facilitates cleaning or replacement.

Advantageously, it can be foreseen that the attachment of the lining is so easy that by not attaching the lining during the manufacture of the helmet, the manufacturing speed and cost can be easily reduced and it is subject to the individuality of the buyer. Moreover, it is possible to provide the user with a predetermined helmet color that represents different kinds of linings and personalities.

It will be appreciated that the scope of protection of the present invention should not be limited to the particular embodiments illustrated, but should also extend to other structural variations that meet the same requirements.

For example, the notches 5a may differ in shape and number from those shown in the figures.

Moreover, although the fixed lining is shown to be attached only to the periphery of the helmet core, the lining can cover the entire core as a whole without departing from the protection scope of the present invention.

Finally, the elements forming the removable modular lining can be lined differently according to other requirements or for technical and / or sanitary purposes.

According to the present invention, it is possible to provide a helmet lining that can be effectively divided into elements so that it can be perfectly attached to the hemispherical surface of the helmet core, and can be easily removed and reattached to allow cleaning or replacement whenever required. .
