Description

IMPROVED SUIT FOR MOTORCYCLISTS"

DESCRIPTION

The present invention relates to an improved suit, in particular for otorcyclists, and a process for elasticizing a region of a motorcyclist's suit.

A suit for motorcyclists is known from the patent EP960350 B1 in the name of Applicant. The known suit is shown in Figure 1. In particular, as can be seen in Figure 1, the known elastic suit is made of leather and has an essentially U-shaped elasticized band denoted overall by 2. The band extends with two wings 4 which depart from the lateral portion of the chest, run along the flanks and are joined together at the rear by a transverse section 6 running along the lower back, also called the lumbar section.

In order to form these elasticized sections, with reference to Figure 1, and in particular the elasticized "U" band 2, three pieces of elastic fabric (not visible in Figure 1) corresponding to the wings on the flanks 4 and to the lumbar section 6 of the "U" band 2 are cut, so that the direction of greatest elastic yielding is orthogonal to the longitudinal extension of said U-shaped elasticized band 2. The three pieces of elastic fabric cut in this way are subjected to a tangential tensile force on a special frame. A leather layer (which forms the outer layer of the suit) is fixed to each of them by means of stitching operations carried out on the whole assembly.

At the end of these operations the leather thus fixed to the elastic fabric is removed from the frame so that it assumes again its original configuration, resulting in the leather being made elastic.

Then the other pieces of elastic fabric are cut and applied using the same procedure described above in other zones of the suit to be elasticized.

From the above it is clear that the known suit offers significant advantages and in particular:

- it allows a wide range of movements to be performed, both from the riding position and from the erect position and generally from any position;

- it enables, as a result, a greater level of active safety of the motorcyclist to be achieved owing to this greater possibility of movement;

- it improves substantially the adherence of the suit to the motorcyclist's body and its consequent aerodynamic properties in the riding position.

One technical problem forming the basis of the present disclosure, which has been recognized by the author of the present disclosure and forms part of the same invention described here, consists in the fact that the known suit, although advantageous from many points of view, is not configured to allow adaptation to a large number of movements, but is limited to a precise number of predetermined movements.

This technical problem is solved by a suit for motorcyclists and a process according to the respective independent claims. Secondary characteristics and particular embodiments forming the subject of the present disclosure are defined in the respective dependent claims.

In particular, the technical problem is solved by providing a suit provided with an elastic or elasticized U-shaped band, wherein at least one of or both wings of the elastic or elasticized "U" portion and/or the lumbar section has/have a yielding direction or orientation which is different along the respective longitudinal extension of the wing or the lumbar section respectively of the elastic or elasticized "U" band, namely at least one of or both of the two wings and/or the lumbar section of the elastic or elasticized "U" band has/have a yielding orientation which is variable along its extension. In other words, at least one of the two wings and/or the lumbar section of the elastic or elasticized "U" band has or each have at least two yielding directions or orientations which are different from each other. The yielding direction is a direction orthogonal to the longitude or length of the respective wing or of the lumbar section, respectively, of the elastic or elasticized band.

The yielding direction is the direction of elasticity. In other words, the single wing of the "U" and/or the lumbar section of the "U" exhibits a defined elastic behaviour. The direction of elasticity, i.e. the direction of the elastic behaviour varies along the extension of the single wing of the "U", and/or of the lumbar section of the "U".

In the continuation of the present disclosure, elastic or elasticized "U" band is understood as meaning a suit portion which is situated mainly in the region of the back of a user and which extends from the chest, passing across the flanks, and extends transversely in the lumbar region.

Preferably, the band is elasticized, namely is made elastic by the presence of a plurality of pieces of elastic material. Each piece is fixed in an elastically deformed condition, on an internal side facing during use a user, to an overlying layer of the suit which, when the suit is worn, is the outer layer. More particularly, each piece is fixed to the outer layer of the suit in a respective zone of the elasticized "U" band. In particular, each piece is subjected to a tangential tensile force on a special frame and a layer intended to be a layer of the suit, preferably an outer layer, is fixed onto each piece. Stitching operations are carried out on the whole double-layer assembly formed by the elastic piece in the tensioned or elastically deformed condition, so as to create a series of stitches parallel to each other. At the end of these operations the layer thus fixed to the elastic piece is removed from the frame so that it assumes again its original configuration, thus making the layer associated with it elastic. The elastic piece includes, by definition, elastomeric fibres, such as Lycra.

The layer assumes a corrugated or curled configuration. Each piece is therefore associated with the layer in the same way. In order to provide a predefined yielding orientation, or direction of elastic behaviour, the piece of elastic material is tensioned in the final yielding direction or orientation to be obtained. The stitches are arranged parallel to each other and orthogonal to the yielding direction. Yielding direction is understood as meaning the greatest yielding direction, which forms an angle preferably of 90 degrees with the direction of extension or length of a respective section of the elastic or elasticized band, i.e. of one or each wing and/or of the bottom section. In the embodiment in which the elasticity is obtained by means of parallel stitches, the yielding orientation or direction is substantially orthogonal to the stitches.

In this way, when the suit is worn, a given region of the suit which is placed under tension by the user gives way in a preferred direction and therefore a preferred yielding capacity, or direction of elastic behaviour, or direction of elasticity, is obtained. For example, when the suit is worn, a yielding capacity in a direction from the bottom upwards and vice versa, or towards a right-hand side or left-hand side or a given spatial orientation is obtained.

The layer is a layer which, as mentioned, is intended to be an outer layer of the suit and is made of a so-called abrasion-resistant material in compliance with the standards for motorcycling suits.

The elastic or elasticized U-shaped band is referred to below in the continuation of the present description for the sake of brevity as "U" band and comprises a lumbar section or bottom section and two side wings.

The bottom section occupies a lumbar area of the suit and side wings extend continuously from the bottom section along the flanks as far as the chest in the region of the armpits.

As mentioned above, according to the present invention, one or each of the wings of the "U" band and/or the bottom side of the "U" band do not have a constant yielding orientation, or a single yielding orientation, along the respective wing of the "U" or along the respective bottom section of the "U", but have smaller length sub-sections each characterized by a respective, precise and predefined, yielding direction or orientation.

In particular, for example one wing of the "U" band has a first sub-section along a flank having one yielding direction and a second sub-section on the chest having a respective second yielding direction. Each first yielding direction and second yielding direction is different also from the yielding direction of the bottom section of the "U" band. If the suit is positioned on a plane in its conventional position with the U having its cavity directed towards north, the first sub-section of the first wing of the "U" band on the right flank is oriented in a south west - north east direction, and the second sub-section on the chest is oriented in a south east - north west direction. The first sub section of the second wing of the "U" band on the left flank is oriented in a south east - north west direction, and the second sub-section on the chest is oriented in a south west - north east direction. The orientation of the bottom band is in a north to south direction. The inclination of the first sub-section with respect to the north-south direction is preferably different from the inclination of the second sub-section of the same wing. Preferably, the orientations are chosen depending on the yielding action to be obtained. A suit with a U-shaped band having at least five yielding axes, or so-called "pentaxial" elasticity, is therefore obtained.

The first sub-section of one or each of the two wings of the "U" band on the respective flank allows lateral bending of a user's flank to the right and left. The second sub-section of one or each wing of the "U" band allows expansion of the chest when the suit is worn and the arms to perform a forwards movement, for example onto the handlebars in the riding position, or simple actions for normal mobility of the user. Preferably, both the wings of the "U" band have a first sub-section and second sub-section with a different yielding orientation. Preferably, the two wings of the "U" band are identical and even more preferably are symmetrical with respect to a median sagittal plane of the human body when the suit is worn. In other words, preferably the "U" band is symmetrical with respect to a sagittal plane of the suit when it is worn. Alternatively, for specific anatomical reasons, it is also possible for the wing of the "U" band on the right side of the suit to be different from the wing of the "U" band on the left side.

Even more preferably, the "U" band includes, as an extension of each wing of the "U" band, a third sub-section having a yielding orientation different from that of the other sub-sections. The third sub-section extends in the region of each shoulder blade around each shoulder of the suit. A suit with seven yielding axes is therefore obtained.

As already mentioned above, the layer overlying each elastic piece is a layer made of abrasion-resistant material, which may be leather or imitation leather or other resistant material, referred to below for the sake of brevity and easy reference as "leather layer". Preferably, according to a preferred aspect of the invention, the leather layer forms a single layer for the entire "U" band, namely it consists of a continuous layer without interruptions.

Preferably, therefore, there are no stitches in the leather layer at the transition point between any parts of the "U" band, not even between one sub-section and another sub-section with a different yielding capacity in the same side wing of the "U" band.

In order to obtain a "U" band with a single leather layer, the following preferred process is performed.

In a first step, a first elastic piece is fixed to the leather by means of a plurality of parallel stitches so as to form the bottom section. In a second step, following the first step, a respective second elastic piece is fixed with a plurality of parallel stitches on the second sub-section of the first wing of the "U" band and, similarly by means of a plurality of parallel stitches, a respective third elastic piece is fixed on the second sub-section of the second wing of the "U" band. Fixing may be performed automatically using suitable sewing machines, so as to form the plurality of stitches parallel to each other. During the second step, in order to facilitate fixing by means of sewing machines, the leather layer regions may be temporarily brought close together so as to form, during the same stitching step, the two second sub-sections of the two wings of the "U" band.

Alternatively, the bottom section may be fixed after the two second sub sections of the two wings of the "U" band.

In a third step, following the second step, a respective fourth elastic piece is fixed by means of a plurality of parallel stitches on the first sub-section of the first wing of the "U" band and similarly a fifth piece is fixed by means of a plurality of parallel stitches on the first sub-section of the second wing of the "U" band. Fixing is performed automatically by means of sewing machines, so as to form the plurality of stitches parallel to each other. Preferably, the sewing machine is guided manually so as to match up or align each stitching of the bottom section with each stitching of the first sub-section of each first wing and second wing of the "U" band and each stitching of the first sub section of both wings with each corresponding stitching of the second sub section of the respective wing of the "U" band. Preferably, therefore, a continuous series of stitches without interruptions between the bottom section and each wing of the "U" band is obtained.

A preferred example of embodiment of the invention is described in detail below with reference to the attached drawings in which:

Figure 1 shows a rear elevation view of a suit according to the prior art;

Figure 2 shows a rear elevation view of a suit according to the present invention;

Figure 3 shows a rear elevation view of a "U" band of a suit according to the present invention on a larger scale than in Figure 2 and extended on a plane;

Figure 4 shows a side view of a "U" band of a suit according to the present invention on a larger scale than in Figure 2 and extended on a plane;

Figure 5 shows a further view from behind of a portion of a suit according to an embodiment of the present disclosure.

With reference to the attached figures, a suit for motorcyclists 102 is described. The suit 102 comprises an elastic U-shaped band 103. The elastic U-shaped band 103 is a portion of the suit in the region of the back of a user, which is preferably elasticized by the presence of a plurality of pieces of elastic material (not visible in the drawings). Each piece is fixed, on an internal side facing during use a user, to an overlying layer of the suit which, when the suit is worn, is the outer layer.

More particularly, each piece is fixed to the outer layer of the suit in a respective zone of the "U" band 103. The layer 107 assumes a corrugated or curled configuration and is elasticized by means of the underlying piece of elastic material. The layer 107 is a layer which, as mentioned, is intended to be an outer layer of the suit 102 and is made preferably of leather.

The elasticized band 103 comprises a bottom section 106 and two side wings 104 and 105.

The bottom section 106 occupies a lumbar area of the suit and the side wings 104 and 105 extend continuously from the bottom section 106 along the flanks as far as the chest in the region of the armpits.

Preferably, the two wings 103, 104 of the "U" band 103 are identical and even more preferably are symmetrical with respect to a median sagittal plane of the human body when the suit is worn.

In the embodiment shown, each of the wings 104, 105 of the "U" band has sub-sections 110, 111, 112 and 113 with a smaller length, each characterized by a respective precise yielding direction or orientation substantially orthogonal to the length of the respective sub-section.

In particular, if the suit is imagined as being positioned on a plane as shown in Figure 3 with the cavity of the U in a direction conventionally established as being a north direction, the first sub-section 110 of the first wing 104 of the "U" band on the right flank is oriented in a south west - north east direction D1 and the second sub-section 111 on the chest is oriented in a south east - north west direction D2. The first sub-section 112 of the second wing 105 of the "U" band on the left flank is oriented in a south east - north west direction D3, and the second sub-section on the chest 113 is oriented in a south west - north east direction D4. The orientation directions are indicative and represented by means of arrows in Figure 3. The yielding direction of the bottom layer 16 is in a north-south direction D5. The inclinations of the first sub-section 110, 112 and the second sub-section 111, 113 of the same wing 104, 105 with respect to the north-south axis D5 are different from each other. Preferably, the orientations are chosen depending on the yielding capacity to be obtained. A suit with five yielding axes, or so-called "pentaxial" elasticity, is therefore obtained.

The first sub-section 110, 112 of one or each of the two wings 104, 105 of the "U" band 103 on the respective flank allows lateral bending of the flank of a user to the right and left. The second sub-section 111, 113 of one or each wing 104, 105 of the "U" band allows expansion of the chest when the suit is worn and the arms to perform a forwards movement, for example onto the handlebars in the riding position, or simple actions for normal mobility of the user.

It is also possible to provide sub-sections with a different yielding capacity for the bottom section 106.

Even more preferably, the "U" band includes, as an extension of each wing of the "U" band, a third sub-section 120, 121 having a yielding orientation different from that of the other sub-sections. The third sub-section extends in the region of the shoulder blade around the respective shoulder. A suit with seven yielding axes is therefore obtained.

Figure 5 shows the yielding directions obtained with the suit.

The present disclosure also relates to a process for making a U-shaped portion of a suit for motorcyclists 102 elastic.

The process involves forming a bottom elastic strip 106 of the "U" band intended to be placed in a lumbar area of the suit 102, forming a first sub section 110 of a first wing 104 of the "U" band and a first sub-section 112 of a second wing 105 of the "U" band, and forming a second sub-section 111 of the first wing 104 of the "U" portion and a second sub-section 113 of the second wing 105 of the "U" band. In particular the first wing 104 and the second wing 105 each extend from the chest across a respective flank of the suit 102 as far as a respective end of the bottom section 106 of the "U" band. The first sub-section 110, 112 of one or each wing 104, 105 of the "U" band has a yielding direction different from that of the second sub-section 111, 113 of the same wing 104, 105.

Preferably: - in a first step, in order to form the bottom section 106 of the "U" band 103, a first piece of elastic material is fixed by means of a plurality of stitches parallel to each other on an internal side of the layer 107 in an elastically deformed condition in the region of a respective lumbar or lower back area of the suit 102, so as to cause respective corrugation or curling of the layer 107;

- in a second step, in order to form the second sub-section 111 of a first wing 104 of the "U" band 103, a second piece of elastic material is fixed by means of a plurality of stitches parallel to each other on an internal side of the layer 107 in an elastically deformed condition on a first side, for example right side, between a chest area and a flank area towards the back, so as to cause corrugation or curling of the layer 107 and then, in order to form a second sub-section 113 of the other wing 105 of the "U" band, a third piece of elastic material is fixed by means of a plurality of stitches on an internal side of the layer in the elastically deformed condition on a second side, for example left side, between a chest area and a flank area towards the back, so as to cause corrugation or curling of the layer;

- in a third step, in order to form a first sub-section 110 of one of the wings 104, a fourth piece of elastic material is fixed by means of a plurality of stitches parallel to each other on an internal side of the layer 107 in an elastically deformed condition on one or the other of the first side and second side, in a flank area towards the lower back, so as to cause corrugation or curling of the layer 107 and then, in order to form a first sub-section 112 of the other of the wings 105 of the "U" band, a fifth piece of elastic material is fixed by means of a plurality of stitches parallel to each other on an internal side of the layer in the elastically deformed condition on the other one of the first side and second side, in a flank area towards the lower back, so as to cause corrugation or curling of the layer 107.

Preferably, the "U" band is formed with a single leather layer and the elastic pieces are fixed to the same leather layer. In particular, as a result thereof, during the aforementioned first step, the elastic piece is fixed to the leather layer in order to form the bottom section 106. In the second step, following the first step, a respective elastic piece is fixed to the same leather layer on the second sub-section of the first wing of the "U" band and the second sub section of the second wing of the "U" band. Fixing may be performed automatically using suitable sewing machines so as to form the plurality of stitches and seams parallel to each other. During the second step, in order to facilitate fixing by means of sewing machines, the leather layer regions may be temporarily brought close together so as to form, during the same stitching step, the two second sub-sections of the two wings of the "U" band.

In the third step, following the second step, a respective elastic piece is fixed to the same leather layer on the first sub-section of the first wing of the "U" band and the first sub-section of the second wing of the "U" band. Fixing is performed automatically by means of a sewing machine so as to form the plurality of stitches parallel to each other. Preferably, the sewing machine is guided manually so as to match up or align the stitching of bottom section with each stitching of the first sub-section of each of the first wing and the second wing of the "U" band and match up each stitching of the first sub-section of each of the first wing and the second wing of the "U" band with the respective stitching of the second sub-section of the first wing and the second wing of the "U" band respectively. A continuous series of stitches without interruptions between the bottom band and each wing of the "U" band is therefore obtained.

The order of the stitching steps may also be changed, and for example the bottom section 106 may be fixed after the second sub-section 11 of the first wing 104 and the second sub-section 113 of the second wing 103.

The subject-matter of the present disclosure has been described hitherto with reference to preferred embodiments thereof. It is to be understood that other embodiments relating to the same inventive idea may exist, all of these falling within the scope of protection of the claims which are illustrated hereinbelow.

Process according to claim 15, wherein, in a first step, in order to form the bottom section (106) of the "U" band (103), a first piece of elastic material is fixed by means of a plurality of stitches parallel to each other on an internal side of the layer (107) in an elastically deformed condition on a respective lumbar or lower back area of the suit (102), so as to cause respective corrugation or curling of the layer (107), a second step wherein in order to form the second sub-section (111) of a first wing (104) of the "U" band (103), a second piece of elastic material is fixed by means of a plurality of stitches parallel to each other on an internal side of the layer (107) in an elastically deformed condition on a first side, for example the right side, between a chest area and a flank area towards the back, so as to cause corrugation or curling of the layer (107), and in order to form a second sub-section (113) of the other wing (105) of the "U" band, a third piece of elastic material is fixed by means of a plurality of stitches on an internal side of the layer in an elastically deformed condition on a second side, for example left side, between a chest area and a flank area towards the back, so as to cause corrugation or curling of the layer, a third step wherein in order to form a first sub-section (110) of one of the wings (104), a fourth piece of elastic material is fixed by means of a plurality of stitches parallel to each other on an internal side of the layer (107) in an elastically deformed condition on one or the other of the first side and the second side, in an area of the flank towards the lower back, so as to cause corrugation or curling of the layer (107), and, in order to form a first sub section (112) of the other one of the wings (105) of the "U" band, a fifth piece of elastic material is fixed by means of a plurality of stitches parallel to each other on an internal side of the layer in an elastically deformed condition on the other one of the first side and the second side, in an area of the flank towards the lower back, so as to cause corrugation or curling of the layer (107).

17. Process according to any one of the preceding claims 15 or 16, wherein the layer (107) is a single continuous layer without interruptions.

18. Process according to any one of the preceding claims 16 or 17, wherein the second step is performed automatically with sewing machines, so as to create the plurality of stitches and seams parallel to each other.

19. Process according to any one of claims 16 to 18, wherein during the second step, in order to facilitate fixing by means of sewing machines, the layer regions and respective second piece and third piece are temporarily brought close together so as to perform during the same stitching step fixing of the respective pieces.

20. Process according to any one of the preceding claims 16 to 19, wherein the third step is carried out by manually guiding the layer and the respective pieces by means of a sewing machine so as to create the plurality of stitches parallel to each other and so as to match up or align:

- each stitching of the fourth piece with a corresponding stitching of the first piece respectively,

- each stitching of the fourth piece with a corresponding stitching of the second piece respectively

- each stitching of the fifth piece with a corresponding stitching of the first piece respectively

- each stitching of the fifth piece with a corresponding stitching of the third piece respectively.

21. Process according to any one of claims 14 to 20, wherein said one or each wing (104, 105) of the "U" band (103) and/or the bottom section (106) of the "U" band (103) have a direction of elastic behavior which varies along the respective longitudinal extension of one or each wing (104, 105) of the "U" band (103) and/or of the bottom section (106) of the "U" band (103)

22. Process according to any one of claims 16 to 21, wherein the process is a process for making the elastic or elasticized band of a suit for motorcyclists (102) according to any one of claims 1 to 13.

23. Suit for motorcyclists (102) according to any one of claims 1 to 13, made using the process according to any one of the preceding claims.
