DESCRIPTION

Pad pad for cycling shorts.

The present invention relates to a pad for cycling bib. In US2005 / 210570, a seat pad for a cycling garment is disclosed. Currently, shorts provided with an anatomically contoured pad pad to improve the comfort of sitting in a saddle are, to date, an essential part of cycling equipment, as a sports activity.

Said protection is used to avoid excoriations and abrasions on the body parts that are in contact with the bicycle saddle.

In fact, it is known that after many kilometers traveled on a bicycle, the continuous pressure of the body and bones ischia on the saddle can cause an uncomfortable pain, which can jeopardize the proper exercise of the athlete.

Currently, these padding pads are manufactured, for example, by coupling and heat sealing several layers of layered polyurethane, with thermoforming adhesive and subsequent bonding procedures or high frequency thermal bonding of the fabrics with the polyurethanes.

Pad pads of a known type provided by polyurethane foams suffer from significant technical limitations, mainly due to poor breathability and the presence of rigid bonding points of the layers, which affect the comfort and reliability of the product at over time

The object of the present invention is to provide a pad for cycling bib able to obviate the mentioned limitations of pad for cycling bib known.

Within this objective, an object of the invention is to provide a pad of pad that is more comfortable and at the same time no less breathable than pad pad of the known type.

Another object of the invention is to provide a pad that is anatomically compatible with the needs of the athlete.

Another object of the invention is to provide a pad of pad that can be applied to shorts of a type known by methods known per se.

A further object of the invention is to provide a pad that can be made with technologies known per se.

This objective and these and other objects, which will be more clearly shown below, are achieved by means of a pad according to claim 1.

Other features and advantages of the invention will become more apparent from the description of a preferred, but not exclusive, embodiment of a pad according to the invention, which is illustrated by way of non-limiting example in the accompanying drawings, in which:

Figure 1 is a perspective view of a pad according to the invention.

Figure 2 is a schematic view of a part of a cross section of the pad according to the invention.

Figure 3 is a view of a rough piece of the pad according to the invention.

Referring to the figures, a pad for cycling bib according to the invention is generally indicated by reference numeral 10.

Pad pad 10 comprises

- a first layer 11 of fabric, directed towards a user in the use configuration,

- a second intermediate layer 12 made of soft polyurethane foam,

- a third intermediate layer 13 made of high density polyurethane foam,

- a fourth layer 14 directed outwards in the use configuration, made of a breathable filter foam, for the protection of the anatomical parts.

The second layer 12, made of soft polyurethane foam, has a density between 50 kg / m3 and 80 kg / irP, and preferably 65 kg / m3; the second layer 12 has the particularity that it can be worked by sewing and, therefore, can be altered, together with the first layer of fabric 11, by sewing seams to fix them to a pair of cycling shorts.

The third layer 13, made of high density polyurethane foam, has a density between 100 kg / irP and 140 kg / irP, and preferably 120 kg / irP; the third high density layer 13 acts substantially as a support for the subsequent fourth layer 14.

The fourth layer 14, which is breathable and for the protection of the anatomical parts, is constituted by an expanded polyurethane based on polyether, which is crosslinked and has a density between 60 kg / m3 and 100 kg / irP, and preferably of 80 kg / irP; the fourth layer 14 is called "filter" because it has the peculiarity of allowing the passage of air and absorbs sweat and liquids in general, however, without retaining them, but rather allowing them to evaporate and, therefore, remains substantially dry; Since it is breathable, in addition to protecting the anatomical parts, it also ensures a certain temperature control in the same areas.

The second layer 12, of soft polyurethane foam, has a thickness between 3 mm and 5 mm, and preferably 4 mm.

The third layer 13, of high density polyurethane foam, has a thickness between 3 mm and 5 mm, and preferably 4 mm.

The fourth layer 14, which is breathable and for the protection of the anatomical parts, has a thickness between 6 mm and 10 mm, and preferably 8 mm.

The layers 11, 12, 13, 14 are joined together by a cold crosslinking adhesive, so that they define a multilayer block 20, as shown in Figure 3.

The pad 10 presents, as clearly shown in Figure 1,

- parts in relief with a thickness that increases progressively from the edge towards the interior, such as the first part 15, which is thicker than the first layer 11 of fabric; and the second part 16, which is thicker than the first part 15;

- and anatomically contoured raised parts, for example raised parts 17, 18, to support, for example, the ends of a user's ischia.

The raised parts 15 and 16 and the anatomically contoured raised parts 17 and 18 are not compressed, that is, they are presented for use without having undergone pre-compression processes that could have reduced their thickness and smoothness, and therefore , with the benefits of breathability and cushioning of the impact of the original materials.

The raised parts 15, 16, with a thickness that progressively increases from the edge inwards, and the anatomically contoured raised parts 17, 18 are provided by means of processes by which material is removed from the multilayer block 20.

In particular, the raised portions 15 and 16 and the anatomically contoured raised parts 17 and 18 are provided by trimming processes.

In practice, it has been considered that the invention achieves the objective and the intended objects.

In particular, the invention provides a pad of pad that is more comfortable and at the same time no less breathable than pad pad of the known type.

In addition, the invention has provided a pad pad that is anatomically compatible with the user's needs.

In addition, the invention has provided a pad of pad that can be applied to shorts of a type known by methods known per se.

In addition, the invention provides a pad of pad that has no stitches or rigid parts that are compressed by thermoforming, for the benefit of softness and general comfort.

In addition, the invention provides a pad of pad that is provided without a post-formation adhesive bond and whose layers are firmly bonded before modeling processes by removing material.

The invention thus conceived is susceptible of numerous modifications and variations, all of them within the scope of the appended claims.

5 In practice, the materials used, provided they are compatible with the specific use, as well as the contingent shapes and dimensions, can be any according to the requirements and current technique.
