Description

Title of the invention: Protective clothing technical field

[0001] This description relates to protective clothing intended for motorcycling, in particular off-road motorcycling. Previous technique

[0002] It is known that motorcycling is an activity that presents risks for the rider due to the speed at which they travel and the limited protection offered by the motorcycle's structure. Risk includes a collision of the motorcycle and / or the rider with another vehicle or an obstacle, or a fall by the rider resulting from a loss of control of the motorcycle, causing, for example, the rider to slide on the ground or the rider to be violently thrown from the seat and launched into the air before impacting the ground.

[0003] To reduce the risk of injury, motorcyclists wear protective clothing. Such protective clothing is generally reinforced in certain areas, typically at the shoulders, elbows, and back, to limit the impact forces acting on the garment. Such protective elements are called "passive".

[0004] Protective clothing is also generally equipped with inflatable protective devices (or "airbags"), which activate automatically when special sensors detect a potentially very dangerous risk in the event of particularly sudden impacts and / or braking. In contrast to passive protective elements, airbags constitute "active" protective elements.

[0005] Protective clothing as described above is generally intended for road use and, for this purpose, does not include chest protection since this is not mandatory for road use. However, for off-road motorcycling (also called "motocross"), i.e., riding off-road, chest protection is required for the rider.

[0006] Therefore, to combine all the protective gear, including an airbag and chest protector, the motocross rider must layer a "road" protective garment as described above and a chest protector. A chest protector typically consists of a shell designed to be placed over the rider's chest and held in place by a strap system. Such a layering of protective gear has the disadvantages of being time-consuming and difficult to put on, and of being uncomfortable.

[0007] In addition, protective clothing for road driving is generally made of abrasion-resistant material, leather or synthetic material, but which in return is not very breathable and therefore poorly suited to the practice of motocross.

[0008] Finally, known protective clothing generally includes a central zipper at the front for donning and fastening the garment in the conventional manner of a jacket. However, such a central zipper prevents the rider from achieving optimal chest protection, as the chest is separated by the central zipper. Summary

[0009] Protective clothing adapted for motorcycling is proposed, the protective clothing comprising: - a front part and a back part connected to each other so as to form a top opening suitable for the passage of the user's head, a bottom opening suitable for the passage of the user's torso and a pair of side openings each suitable for the passage of one of the user's arms, - a pair of side zippers connecting the front and back sections laterally, each zipper extending between the bottom opening and one of the respective side openings in the pair of side openings, - a front passive protection element fixed, preferably in a removable way, to the front part, the front passive protection element being unique and monobloc.

[0010] Each zipper can be arranged at a respective side of the garment, each zipper preferably extending in a straight line between the respective side opening and the bottom opening.

[0011] The passive front protection element can be suitable for continuously covering at least 50% of the user's thorax, preferably 75% of the user's thorax, and preferably still 90% of the user's thorax.

[0012] The protective garment may include an inflatable protective device attached to the front and / or back part, the inflatable protective device including an inflatable cushion adapted to move from a resting configuration in which the inflatable cushion is deflated to a use configuration in which the inflatable cushion is inflated.

[0013] The inflatable cushion may include a rounded portion to surround at least part of the user's neck, and a pair of front portions to each cover at least a respective part of the thorax, and preferably also the abdomen, of the user, each of the front portions being in fluidic communication with a respective end of the rounded portion.

[0014] The front passive protection element can be arranged above said pair of front portions of the airbag.

[0015] The protective garment may include a single passive protective back element attached to the back part.

[0016] At least one of the side zippers may be self-locking.

[0017] At least one of the front and dorsal parts may comprise, transversely on each side, a flank area which includes one or more tension bands each having a modulus of elasticity greater than that of adjacent areas made of stretchable elastic fabric, so that in use the tension bands offer greater resistance to stretching than the adjacent areas.

[0018] The front part may include a resealable pocket adapted to receive the protective element in a removable manner. Brief description of the drawings

[0021] [Fig.2] is a schematic rear view of the protective garment according to the present description.

[0023] [Fig.4] is an exploded schematic view of the protective garment according to the present description. Description of the implementation methods

[0024] Protective clothing suitable for motorcycling is now described with reference to [Fig. 1]. The garment can be adapted for off-road motorcycling ("motocross" or "enduro"). It is not excluded that the garment described below may also be suitable for road motorcycling.

[0025] The protective garment 10 comprises a front part 11 and a back part 12 connected to each other so as to form a top opening 13 adapted for the passage of the user's head, a bottom opening 14 adapted for the passage of the user's torso and a pair of side openings 15 each adapted for the passage of one of the user's arms.

[0026] A longitudinal direction DI of the garment can be defined between the lower end and the upper end. The longitudinal direction DI can be close to, or even coincide with, a vertical direction when the protective garment 10 is worn by a user in a standing position. The lower opening 14 and the upper opening 13 can be opposed to each other along the longitudinal direction Dl.

[0027] In the following, the anteroposterior direction Dap refers to the anteroposterior direction Dap of the garment. The anteroposterior direction Dap is considered to be the same as the direction from front to back of the wearer of the garment. The front portion 11 and the back portion 12 can be consecutive and distinguished along this anteroposterior direction Dap. In other words, the front portion 11 and the back portion 12 can be opposite each other along the anteroposterior direction Dap. The anteroposterior direction Dap can be horizontal when the garment is worn by the wearer in a standing position. The anteroposterior direction Dap can be transverse to the longitudinal direction Dl, and preferably perpendicular to the longitudinal direction Dl.

[0028] A transverse direction Dt can also be defined, transverse to the longitudinal direction Dl and the anteroposterior direction Dap, preferably perpendicular to the longitudinal direction Dl and the anteroposterior direction Dap. The garment may include lateral sides 16 opposite each other along the transverse direction Dt. The lateral openings 15 may be opposite each other along the transverse direction Dt.

[0029] In the following description, when reference is made to absolute positional qualifiers, such as the terms "front," "back," "up," "down," "left," "right," "lateral," etc., or relative positional qualifiers, such as the terms "above," "below," "superior," "lower," etc., or to orientational qualifiers, such as "horizontal," "vertical," etc., reference is made, unless otherwise specified, to the orientation of the figures or of the protective clothing 10 worn by a standing user.

[0030] It is understood that the lower opening 14 of the garment can be larger when the side zippers 20 are wholly or partially open than when they are closed. Notably, the protective garment 10 lacks a zipper connecting the upper opening 13 to the lower opening 14.

[0031] The front portion 11 may be designed to cover at least part of the user's thorax, and preferably at least part of both the thorax and abdomen of the user. The back portion 12 may be designed to cover at least part of the user's back.

[0032] The protective garment 10 may include an upper end. The upper opening 13 may be formed at the upper end. The protective garment 10 may include a lower end. The lower opening 14 may be formed at the lower end.

[0033] The front part 11 and the dorsal part 12 can be connected to each other at the upper end, preferably on either side of the opening upper 13, for example by being a single piece. In other words, the front part 11 and the back part 12 can be connected to each other, or even be a single piece, at the user's shoulders.

[0034] Each of the upper opening 13, lower opening 14 and lateral openings 15 may have a peripheral edge formed partly by the front part 11 and partly by the dorsal part 12.

[0035] Remarkably, the garment includes a pair of side zippers 20 connecting laterally the front part 11 and the back part 12, each zipper extending between the lower opening 14 and a respective side opening 15 among the pair of side openings 15.

[0036] The protective garment 10 also includes a passive protective front element 31 fixed, preferably in a removable manner, to the front part 11, the passive protective front element 31 being unique and monobloc.

[0037] The fact that the passive protective front element 31 is a single, one-piece piece increases the surface area over which the force of an impact is dispersed, thus reducing the force transmitted to the wearer. In other words, this provides better protection for the wearer. Furthermore, the combination of the pair of side zippers 20 and the single, one-piece passive protective front element 31 allows the garment to be put on like a poncho or vest, making it easier to don, especially when the garment is intended to be tight-fitting or even form-fitting.

[0038] Each zipper can be arranged at a respective side 16 of the garment. Each zipper can extend straight between the respective side opening 15 and the lower opening 14. Thus, the spacing between the zippers can be maximized to allow the passive protective front element 31 to continuously cover the largest possible area of ​​the user's chest, or even abdomen.

[0039] The side panels 16 of the garment can each be designed to cover at least partially a respective side of the garment's wearer. Thus, each zipper can be arranged to run along a respective side of the wearer. More specifically, each zipper can extend straight along the longitudinal direction Dl. Alternatively, the zippers can be positioned opposite each other along the transverse direction Dt.

[0040] Also, notably, the protective garment 10 may be without a central zipper that would run along the user's chest and / or abdomen.

[0041] The passive protective frontal element may be suitable for continuously covering the user's thorax, and in particular at least 50% of the user's thorax, preferably 75% of the user's thorax, and preferably even 90% of the user's chest. "Continuously" means that the front passive protection element can be adapted to cover the entire chest in one continuous piece without interruption, i.e., without separation between several elements. This distinguishes the passive protective garment from those in which chest protection is achieved by two structurally separate blocks, each covering only one of the user's pectoral muscles. The front passive protection element 31 may include a plate adapted to absorb all or part of an impact force. In other words, the plate can be adapted to transmit only a portion of an impact force to the user.

[0042] The plate can be made of plastic. Alternatively, the plate can be made of an absorbent foam, for example memory foam, which has the advantage of being more ergonomic and more comfortable than plastic.

[0043] The plate can be rigid. Alternatively, the plate can be made of a non-Newtonian expanding material (or fluid), meaning that it has the property of changing its mechanical behavior depending on whether it is handled slowly or rapidly. In its rest state, i.e., when handled slowly, the material can be malleable and / or flexible. When subjected to an impact, the material can harden or stiffen (for example, the molecules composing the material bond together to allow the hardening or stiffening of said material), thus enabling it to absorb and disperse the kinetic energy generated by the impact. Afterward, the material returns to its rest state. Such a material could be D3O®. The plate can also include a honeycomb structure, which allows for better ventilation through the passive protection element.

[0044] The passive front protection element 31 can be adapted to transmit to the user, in response to an impact energy of 50 J, an average residual force of less than 20 kN and a maximum force of 35 kN. The passive front protection element 31 can be adapted to transmit to the motorcyclist, in response to an impact energy of 50 J, a force whose surface distribution is at least 15% of the total surface area of ​​the passive front protection element 31, and preferably at least 30%. The distribution of a force is expressed as a percentage and reflects the surface area over which the impact force is dispersed. The higher the percentage, the larger the dispersion area.

[0045] Also, the passive front protection element 31, in particular the plate, may have a width that corresponds to at least 50% of a minimum width of the front part 11, preferably 75% of a minimum width of the front part 11, and preferably even 90% of a minimum width of the front part 11. The minimum width of the front part 11 may correspond to the smallest measured dimension between the zippers and / or between the side openings 15 according to the transverse direction Dt.

[0046] The protective garment 10 may include an inflatable protective device 40 attached to the front part 11 and / or the back part 12, the inflatable protective device 40 comprising an airbag 41 adapted to switch from a resting configuration in which the airbag 41 is deflated to an operating configuration in which the airbag 41 is inflated. The protective garment 10 thus combines passive frontal protection and active protection by means of an airbag 41, thereby improving the user's protection.

[0047] In the usage configuration, the inflatable cushion 41 can adapt to wrap around the user's spine, neck, rib cage and abdomen.

[0048] The inflatable protective device 40, in its operating configuration, can be adapted to transmit to the motorcyclist, in response to an impact energy of 50 J, an average residual force of less than 4.5 kN and a maximum force of 6 kN. Preferably, the inflatable protective device 40, in its operating configuration, can be adapted to transmit to the motorcyclist, in response to an impact energy of 50 J, an average residual force of less than 2.5 kN and a maximum force of 3 kN.

[0049] The inflatable protective device 40 may include a control element 42 capable of determining a risk situation and controlling the transition from the rest position to the operating position. In other words, the control element 42 may be capable of triggering the inflation of the airbag 41. Activation of the inflation of the airbag 41 may be mechanical, for example by cable, or electronic. The control element 42 may be attached to the dorsal part 12.

[0050] The inflatable protective device 40 may include an inflation member 43. The control member 42 may be adapted to trigger the inflation member 43. The inflation member 43 may include a suitable gas source for inflating the airbag 41, in particular a gas cartridge. The inflation member 43 may be attached to the dorsal part 12.

[0051] The inflatable protective device 40 can be reversible; in particular, the inflatable cushion 41 can be adapted to switch from the operating configuration to the resting configuration. The inflation element 43 can be replaced, particularly after use.

[0052] The airbag 41 may include a rounded portion 41a to surround at least part of the user's neck, and a pair of front portions 41b to each cover at least a respective part of the user's thorax, and preferably also of their abdomen, each of the front portions 41b being in communication fluidic with a respective end of the rounded portion 41a. Each front portion 41b can extend substantially along the longitudinal direction DI or be close to the longitudinal direction Dl.

[0053] In other words, each front portion 41b is pneumatically connected to a respective end of the rounded portion 41a. Such a configuration ensures both good protection for the user and rapid inflation of the airbag 41. This configuration is made possible in particular by the arrangement of the side zippers 20.

[0054] The rounded portion 41a may in particular partially surround the upper opening 13. The rounded portion 41a may have a C shape, the opening of which is arranged at the level of the front part 11 of the garment.

[0055] The passive front protection element 31 can be arranged above said pair of front portions 41b of the airbag 4L. The thorax, and possibly the abdomen, of the user are thus protected both by the passive front protection element 31 and by the inflatable protection device 40.

[0056] The airbag 41 may further include at least a rear portion 41c in fluidic communication with the rounded portion 41a. The front portion 11 and the back portion 12 of the garment may form a pocket adapted to receive the airbag 41 of the inflatable protective device 40. The front portion 11 and the back portion 12 may each include, at least in part, an inner layer and an outer layer between which the pocket receiving the airbag 4L is formed. In other words, the front portion 11 and the back portion 12 of the garment may include a lining forming the pocket that receives the airbag 4L. At the level of this pocket, the front portion 11 and / or the back portion 12 may be formed by the inner layer and the outer layer. The outer layer may be made of an opaque fabric, so as to prevent the airbag 41 from being visible from the outside.

[0057] The protective garment 10 may include a single passive back protection element 32 attached to the back part 12. The protective garment 10 thus combines by itself front and back passive protection, possibly combined in addition with active protection by inflatable cushion 4L II, thus optimal protection of the user is obtained.

[0058] The passive back protection element 32 can be interposed between the back part 12 and the inflatable protection device 40, in particular the control member 42 and / or the inflation member 43. The passive back protection element 32 can include a plate as described with reference to the passive front protection element 31. The passive back protection element 32, in particular the plate, can be adapted to cover at least part of the user's spine.

[0059] The passive back protection element 32 can be adapted to transmit to the motorcyclist, in response to an impact energy of 50J, an average residual force of less than 18 kN and a maximum force of 24 kN. Preferably, the passive back protection element 32 can be adapted to transmit to the motorcyclist, in response to an impact energy of 50J, an average residual force of less than 9 kN and a maximum force of 12 kN.

[0060] The protective garment 10 may be devoid of passive protection at the elbows and / or shoulders of the user in order to offer better mobility to the user.

[0061] At least one of the side zippers 20 may be of the self-locking type. This limits, or even prevents, unintentional opening of the zippers, particularly while driving. In other words, each side zipper 20 may include a self-locking slider, meaning that the slider cannot be moved in the direction of opening and / or closing the zipper without deliberate action by the user. To this end, the slider may include a locking mechanism adapted to lock the slider in a desired position. Thus, the slider cannot be moved in the direction of opening and / or closing without unlocking the locking mechanism.

[0062] At least one of the front portion 11 and the dorsal portion 12 may include, transversely on each side, a flank area comprising one or more tension bands 17, each having a modulus of elasticity greater than that of adjacent areas made of a stretchable elastic fabric, such that in use, the tension bands 17 offer greater resistance to stretching than the adjacent areas. In other words, each tension band 17 exhibits more resistance to elastic deformation than the adjacent areas. In this sense, the tension bands are less elastic or less flexible than the adjacent areas (for the same load).

[0063] Each tension band 17 may have a maximum elasticity rate (or maximum degree of elasticity, before rupture) lower than that of the adjacent areas, in particular between 6% and 10%, preferably equal to 8%.

[0064] Thanks to the more elastic adjacent zones, the flank zones can thus exhibit elasticity allowing separation between the front part 11 and the dorsal part 12, particularly in the anteroposterior direction Dap, and preferably during the transition of the inflatable protective device 40 from the resting configuration to the operating configuration, i.e., during the inflation of the airbag 4L

[0065] Furthermore, each tension band 17 can have a tension that also allows the garment to remain in position on the user when the inflatable protective device 40 is moved from its resting configuration to its operating configuration, i.e., when the airbag 4L is inflated. More particularly, said One or more tension bands 17 can be adapted to limit, or even avoid, rotation of the protective garment 10 on the user when the inflatable protective device 40 is moved from the resting configuration to the operating configuration, i.e. when the airbag 41 is inflated. Thus, the front passive protective element 31 remains in position when the inflatable protective device 40 is moved from the resting configuration to the operating configuration, ensuring optimal protection of the user.

[0066] The flank areas of the front and / or back parts 11 can form, in whole or in part, the lateral sides 16 of the protective garment 10.

[0067] In the case where each of the front part 11 and dorsal part 12 comprises such side zones, each side zone of one of the front part 11 and the dorsal part 12 is directly connected to an associated side zone among the side zones of the other of the front part 11 and the dorsal part 12. This direct connection can in particular be formed by means of one of the lateral zippers 20. The side zones of the front part 11 and dorsal part 12 directly connected to each other are referred to as associated side zones 11a; 12a hereinafter.

[0068] Said one or more tension bands 17 of each side zone may comprise at least four tension bands 17. The associated side zones 11a; 12a may comprise the same number of tension bands 17. Said one or more tension bands 17 may extend over a minimum of 25% of the total surface area of ​​the corresponding side zone 16 in order to ensure sufficient garment support. Furthermore, said one or more tension bands 17 may extend over a maximum of 50% of the total surface area of ​​the corresponding side zone 16 in order to improve the comfort and breathability of the protective garment 10. In particular, the areas adjacent to the tension bands 17 may have a higher permeability (in this case to air) than the tension bands so as to be more "breathable".

[0069] In one embodiment, said one or more tension bands 17 may extend over the entire surface of the corresponding flank area (i.e., over 100% of the total surface of the corresponding flank area). It is understood that in this version, the adjacent areas may be formed by the frontal part or by the dorsal part.

[0070] The tension bands 17 of the associated flank zones 1a; 12a can be aligned in pairs along the longitudinal direction Dl. In other words, each tension band 17 of one of the associated flank zones 1a; 12a can be arranged opposite or facing one of the tension bands 17 of the other associated flank zones 1a; 12a. The tension bands 17 of the associated flank zones 1a; 12a that are longitudinally aligned in pairs can further be separated by the side zipper 20 which connects the associated side areas 1 la; 12a.

[0071] Each tension band 17 can extend perpendicularly to the longitudinal direction Dl. In other words, each tension band 17 can have a principal direction of extension (i.e., along its length) that is perpendicular to the longitudinal direction Dl. Each tension band 17 can extend along the transverse direction Dt and the anteroposterior direction Dap when the garment is worn by the user. Thus, each tension band 17 can follow a path that follows the ribs of the user wearing the protective garment 10. Each tension band 17 can have a length between 2 cm and 6 cm, and preferably around 3 cm. Each tension band 17 can have a width between 2 cm and 3 cm, and preferably around 2.5 cm. The width of each tension band corresponds to a dimension perpendicular to the principal direction of extension and can be measured along the longitudinal direction Dl.

[0072] Each tension band 17 can be made of a fabric comprising elastane and / or polyester. Generally, the fabric from which each tension band 17 is made can comprise between 90% and 94% polyester, and between 6% and 10% elastane. A preferred composition can comprise 92% polyester and 8% elastane. Each elastic band can be made of a fabric with a basis weight of approximately 245 g / m².

[0073] The front portion 11 and the back portion 12 can together form a lower retaining band 18 extending around the periphery of the lower opening 14. The lower retaining band 18 can be annular and include a portion at the front portion 11 and a portion at the back portion 12. The lower retaining band 18 further improves the fit of the protective garment 10 on the user. The retaining band can be a silicone elastic band.

[0074] The front portion 11 may include a closable pocket adapted to removably hold the protective element. Insertion and positioning of the passive protective front element 31 are thus quick and easy. The pocket may be closed by means of a zipper.
