Description

The invention relates to a sports helmet having the features of claim 1.Sport helmets serve to protect the head of an adult or a child from injuries, in particular when performing a sport operation before or when touching foreign bodies such as stones or branches. In the following, the wearer of the sports helmet is referred to generally.The sports helmet protects the head of the wearer from contact with the ground or, for example, with suspended objects such as easts in the event of a fall or during the normal movement sequence.The sports helmet also protects the head of the wearer when colliding with other persons.Sport helmets are used, for example but not exclusively, in bicycle driving, in rescue, in parachute jumping, in climbing and in water sports, in particular in canuing. Sport helmets are also used by skiers and snowboarders.DE 10 2013 209 564 B4 discloses a sport helmet having a movable visor. The visor is connected to the sports helmet via a respective spring element articulated on a respective end face of the visor. Each spring element is fastened to the helmet shell in the interior of the sport helmet.In known sports helmets, the visors are often fastened laterally to the sports helmet in the temporal region by means of a rotation axis. The visor can be folded upwards or downwards by means of a rotary knob.The previously known sport helmets, however, prove disadvantageous because the sport helmet assumes a balancey appearance due to its construction.A further disadvantage is that the visor is comparatively far from the face of the wearer in the closed state. The wearer therefore feels the draft air during driving in comparison with conventional sport glasses, in particular ski glasses.In the case of previously known sighting helmets, the visor is generally folded upwards. Due to the preferably 3-dimensional shape of the commercially available visors, the lower edge of the visor can pull the vision aid of the wearer upwards when folding up.In the present sport helmet, the visor can be lifted very easily over the vision aid, in particular a pair of spectacles. The spectacles thus no longer collide with the sight of the sports helmet.Many known sports helmets have fastening elements for attaching the visor to the sports helmet, which fastening elements protrude beyond the outer contour of the helmet shell of the sports helmet.Such fastening elements generate disturbing secondary noises, in particular at higher speeds.Known fastenings of the visor to the sport helmet also often prove disadvantageous because the visor fastening and the associated adjusting devices can loosen and adjust. Unintentional loosening of the visor relative to the helmet shell and / or relative to the face of the wearer can promote a penetration of a liquid, in particular rainwater and snow, into the interior of the helmet or onto the interior of the visor.In known sports helmets, two separate fastening elements are often guided in the channel in the helmet shell. The separate fastening elements are each fastened separately from one another on the helmet shell. This can lead to different degrees of elasticity on the individual fastening elements, in particular after long use. As a result, the fastening elements each act with an unequal tensile force on the visor and / or indirectly on the face of the wearer.The invention therefore addresses the problem of providing a sport helmet with an associated visor, in which the fixing of the visor on the sport helmet and the adjustment of the position of the visor with respect to the sport helmet are improved with respect to sport helmets known from the prior art. The sport helmet according to the invention is intended to avoid the above mentioned disadvantages.The sports helmet according to the invention is intended to seal better on the face of the wearer in order to avoid an undesired wind. At the same time, sufficient internal ventilation of the visor is to be ensured and there is no condensation on the inside of the visor of the sport helmet.An additional object is to provide a sport helmet in which the visor can be fixed in the respectively selected position relative to the helmet shell. The visor should not unintentionally release from its position relative to the sports helmet.In addition, the object of the invention is to create a sports helmet which has connecting means with which a more easily exchanged damaged or soiled visor of the sports helmet is possible.The further object of the invention is to provide a sports helmet in which the sight of the sports helmet can be exchanged depending on the prevailing visibility conditions. In this way, the safety of the wearer is to be increased.It is a further object of the invention to provide a sports helmet which allows the wearer to wear his vision aid (e.g. eyeglasses) even during the practice of the sport. In addition, the object of the invention is to create a sports helmet which has a slender and modern outer contour.The objects are achieved by a sports helmet having the features of claim 1.Sport helmetThe sport helmet can be formed as an integral helmet. An integral helmet comprises a fixed chin portion. The visor is lockable with respect to the sport helmet.The sport helmet can also be designed as a half-shell helmet. The half-shell helmet comprises a helmet shell which in particular protects the head region above the ears of the wearer.The term sport helmet also includes a so-called jet helmet. The the thethelm does not comprise a chin part such as the integral helmet. The helmet shell of the helmet additionally protects the rear area behind the ears of the wearer.The sport helmet may have a full sight. The full sight covers the full extent of the wearer's face. The full sight protects the wearer's face from wet and dirt. The full sight gives the wearer a particularly good view, since no frames of the sight impair the view.The sports helmet can have at least one ventilation device. The ventilation device comprises openings in the helmet shell of the sport helmet. The openings are closable.For receiving the head of the wearer, the sport helmet has a basket-shaped device on its inner side. The basket-shaped device is referred to below as a basket.The basket is conformable to the periphery of the wearer's head. The sport helmet comprises straps by means of which the basket of the sport helmet and thus the sport helmet itself can be fastened to the head of the wearer. The straps are connected to the basket for receiving the head of the wearer.To adapt the sports helmet to the size of the wearer's head, the straps of the basket are adjustable in length.The straps and / or the basket for receiving the head of the wearer comprise pads which ensure sufficient wearing comfort of the helmet on the head of the wearer.The sport helmet comprises a helmet shell.The sport helmet furthermore has a visor releasably arranged on the helmet shell of the sport helmet.Helmet shellThe helmet shell of the sport helmet is made of at least one material. The material is preferably, but not exclusively, made of plastic.The helmet shell is preferably made of a thermoplastic material. Thermoplastic materials can be, for example, copolymers or elastomer alloys.The helmet shell can also be made of a thermosetting plastic. The thermosetting resin may be a cured resin.By way of example, but not exclusively, the plastic used for producing the helmet shell can be an expanded polystyrene (EPS) or a polycarbonate or a polyamide.In addition, the helmet shell can be a composite material. By way of example and not by way of limitation, the plastic composite material can comprise glass fibers (GRP) and / or carbon fibers (carbon) and / or aramid fibers and / or polyethylene fibers. The aforementioned fibers reinforce the at least one carrier material.The helmet shell manufactured from the composite material comprises an outer shell and an inner shell.The helmet shell can be manufactured from an injection-molded plastic and / or a deep-drawn plastic.The choice of the plastic determines the flexibility and / or the strength and / or the torsional rigidity of the helmet shell. To a predetermined extent, the side walls of the helmet shell of the sport helmet are bendable relative to each other.Channel in the helmet shellA channel is arranged in the helmet shell, which channel serves to receive an elastic fastening element. The elastic fastening element serves for the detachable fastening of the visor to the sport helmet.In the region of the visor, an opening is provided on each of the end faces of the side walls of the helmet shell.The openings communicate with the channel. Via the opening on the one side of the helmet shell, the elastic fastening element is introduced into the channel of the helmet shell. The elastic fastening element is led out of the channel from the opening on the opposite side of the helmet shell of the sport helmet. The elastic fastening element, preferably an elastomer, is not covered by the visor.The channel for receiving the elastic fastening element extends in the helmet shell all around and continuously over both side walls and on the rear side of the wearer's head.The channel is formed as a bore in the interior of the helmet shell. The bore is surrounded over its entire circumference by the material of the helmet shell.The channel may have a round or oval cross section. The cross section of the channel can, however, also assume any other geometric shape.The channel may include a liner. The liner may be made of plastic. The liner may also be made of metal or any other material. The lining is preferably designed such that the elastic fastening element is not impaired in its elastic properties by tensile and / or compressive movements on the fastening element.The lining can be designed as a hose. The lining can have material reinforcements at least in regions.During the production of the sports helmet, the channel is preferably encapsulated by injection molding with EPS foam (Styropor).The channel and / or its lining of the channel is fully circumferentially closed. However, they can also be open to one side or in sections.The channel and / or the lining protect the material of the helmet shell from indentations and / or incisions caused by an axial and / or radial movement of the elastic fastening element in the interior of the channel of the helmet shell of the sport helmet.The channel counteracts the cutting of the elastic fastening element into the material of the helmet shell when a tension or a tension introduction is exerted on the elastic fastening element within the side walls of the helmet shell and / or in the rear region of the helmet shell.According to one embodiment of the invention, the channel which receives the elastic fastening element is a groove running in the helmet shell.The term groove is understood to mean an elongate depression which preferably runs in the inner shell of the helmet shell of the sport helmet. The groove extends on both side walls of the helmet shell and on the rear side of the helmet shell. The groove serves to receive and guide the elastic fastening element.In the following, a channel is generally referred to instead of a groove.The channel may have a round cross section. The channel can also have an angular or another cross section.On the side of the channel that faces the elastic fastening element, the channel has a coating. The coating serves for improved sliding of the elastic fastening element with respect to the channel. The coating prevents abrasion of the material of the elastic fastening element when the elastic fastening element moves under tension with respect to the channel.The channel is made of a plastic. The channel can also be made of metal or of any other material.Protective sleeveThe elastic fastening element can be inserted into and / or removed from openings on the side walls of the helmet shell.One embodiment of the invention provides that a protective sleeve is inserted into each opening for this purpose. The protective sleeve protects the elastic fastening element protruding from the opening in the event of an expansion or contraction with respect to the helmet shell.The protective sheath can be made of a plastic. The protective sheath may also comprise a metal material or any other material.To protect the elastic fastening element with respect to the helmet shell and / or to protect the helmet shell with respect to the elastic fastening element, the protective cover can have a soft structure. However, it is also possible for the structure of the protective sleeve to have a hard material structure.The protective sleeve counteracts the cutting of the elastic fastening element into the material of the helmet shell when a tension or a tension introduction is exerted on the elastic fastening element within the side walls of the helmet shell and / or in the rear region of the helmet shell.Elastic fastening element of the visor to the helmetThe elastic fastening element connects two regions of the visor of the sport helmet to one another. Preferably, the two regions are the lateral end faces of the visor. The elastic fastening element is introduced into the helmet shell through an opening on the side wall of the helmet shell. The elastic fastening element extends continuously in the helmet shell on both side walls and on the rear side of the helmet shell. At the outlet opening in the opposite side wall of the helmet shell opposite the inlet opening, the elastic fastening element is led out of the helmet shell.The resilient fastener has a length at least equal to the length of the channel that receives the resilient fastener for releasably securing the visor to the sport helmet.With the elastic fastening element, the fixation of the visor connected to the elastic fastening element can be adjusted and / or changed with respect to the helmet and / or with respect to the face of the wearer of the sport helmet.The elastic fastening member is an elastic body.The elastic fastening element can be designed as a rubber cord, as a rubber cord or as a rubber band. The elastic fastening element can also be designed as an elastic band.A further embodiment of the invention provides that the elastic fastening element comprises an elastomeric material. An elastomer is an elastically deformable plastic.The elastic fastening element is designed such that its extensibility does not change in a disadvantageous manner even at different external temperatures.Generally, reference is made below to the elastic fastening element.The elastic fastening element has a constant length and / or constant elasticity over a predetermined period of time, in particular the intended service life of the sports helmet.The elastic fastening element can also have a net structure which is constructed from elastic fibers.It is further provided that the elastic fastening element is extensible in the longitudinal direction after application of a tensile force to at least one end protruding from the opening in the side walls of the helmet shell.With a reduction of the tensile force, the elastic fastening element resumes its original and length.A tensile force is exerted on the elastic fastening element, which tensile force extends within the helmet shell preferably in the direction of and / or in extension of the longitudinal axis of the channel.A tensile load can be exerted on the elastic fastening element. The tensile load causes an elastic change in length of the elastic fastening element. After the tensile and / or compressive load has been eliminated, the elastic fastening element resumes its original shape and length.The invention provides that the elastic fastening element is stretchable in a direction aligned with the channel.The term elongation refers to a relative change in length of the elastic fastener when a tension is applied to the elastic fastener.The elastic fastening element can be stretched in the region between the openings on the side walls of the helmet shell and the visor. The elastic fastening element can be stretched in the region of only one opening. The elastic fastening element can be stretched over the entire channel length.The extension of the elastic fastening element causes the visor, which is connected at least indirectly to the elastic fastening element, to be stretchable in a direction aligned with the channel.In this way, the wearer of the helmet can lift the visor from the helmet and / or from the face and engage in the depression arranged on the outer contour of the helmet shell.An additional embodiment of the invention provides that the elastic fastening element is variable with respect to its tensile force.For this purpose, the elastic fastening element has additional prestressing devices with which prestress can be exerted on the elastic fastening element. The prestressing device can be, by way of example and not exclusively, a spring element or a rubber band.The spring and / or the spring element has resilient properties. The resilient property brings about a particular mobility, flexibility, articulation and / or flexibility of a body.In the following, the spring element is referred to as a spring.The bias voltage can be varied as desired.The extensibility of the elastic fastening element in a direction aligned with the channel has the effect that the fixation on the helmet and / or on the face of the wearer can be canceled.Stretching the elastic fastening element in a direction aligned with the channel prevents the elastic fastening element from being damaged at the openings in the side walls of the helmet shell at the exit of the elastic fastening element.The spring is a rubber body. Alternatively, the spring can also comprise a plastic, preferably an elastomer. The spring can also be a metal body. The springs can also be designed as rubber cord, rubber cord or as flat rubber.The spring can also comprise a combination of a plastic and / or a rubber and / or a metal body. The rubber material can be a plastic or a natural rubber.Another embodiment of the invention provides that the elastic fastening element is a braid of at least two materials.The braid comprises at least two strands of at least one elastic material. In the case of the elastic fastening element in the form of a braid, at least two elastic threads are linked to one another and / or twisted and / or twisted and / or tied together.The formation of the fastening element in the form of a braid has the effect that the elastic fastening element has an increased tear strength.The configuration of the elastic fastening element in the form of a braid furthermore increases the extensibility and / or increases the service life of the elastic fastening element within the channel of the helmet shell of the sport helmet.A further embodiment of the invention provides that at least two elastic fastening elements are arranged. The at least two elastic fastening elements run parallel to one another.In one embodiment, the sports helmet has at least two channels and / or at least two grooves, in each of which an elastic fastening element runs parallel to one another.The fastening elements are preferably arranged parallel to one another in the region of the occipital region or in the region of the skull ceiling of the wearer.The further elastic fastening element can also be arranged in the region of the neck of the wearer of the sports helmet.The arrangement of at least two elastic fastening elements running parallel to one another brings about an improved fixing of the visor with respect to the sport helmet and / or with respect to the face of the wearer of the sport helmet.The arrangement of at least two fastening elements running parallel to one another increases the contact pressure of the visor on the sports helmet or on the face of the wearer and thereby permits a more exact positioning of the visor with respect to the sports helmet or with respect to the face of the wearer.In addition, the captive safety of the visor is significantly increased compared to the sports helmet.A further embodiment of the invention provides that at least two elastic fastening elements are arranged, which extend at an angle to one another, for example converging in a V-shape at the at least one opening on the side wall of the helmet shell.The V-shaped arrangement of the elastic fastening elements can also be provided at another location, preferably on the rear side of the head of the sports helmet. The further elastic fastening element has at least two attachment points on the visor.Via the attachment point, the elastic fastening element is arranged on the visor with a releasable connecting means in a form-fitting or force-fitting manner.The elastic fastening element enables the wearer to be able to wear an optical vision aid (e.g. spectacles) under the visor.The visor is pivotable relative to the helmet shell. In this way, the position of the visor relative to the wearer's face and / or to the helmet shell can be changed as required. Depending on the position of the sight with respect to the helmet shell, the protective effect of the sight can be changed.The connection between the fastening element and the connecting means is maintained after the visor has been released and / or removed from the sports helmet.Visible Elastic FastenerIn a further embodiment of the invention, the elastic fastening element is visible between the opening in the side walls of the helmet shell and the releasable connecting means.For this purpose, the fastening element can be formed in at least two different colors and / or patterns and / or surface structures.The elastic fastening element visible between the opening in the side walls of the helmet shell and the releasable connecting means serves as an optical recognition means and / or as an optical distinguishing feature of the sport helmet for the wearer.The connecting means visible between the opening in the side walls of the helmet shell and the visor serves the wearer of the sport helmet for detaching the visor from the face and / or for detaching it from the outer contour of the sport helmet.The wearer of the sport helmet can thus change the sighting position without having to grasp directly on the outer surface of the visor with his fingers and / or glove.This protects the outer surface of the visor from dirt and / or damage.Sight: SightThe term sight comprises at least one lens. The viewing pane can have a planar orientation at least in regions. The visor can furthermore be curved at least in regions.Hitherto, in contrast to ski glasses, visors have been removed from the helmet only with difficulty.Preferably, however, at least one quick-action closure is arranged on the sports helmet, with the aid of which the visor can be mounted to the sports helmet and dismounted from the latter again in the shortest time.To form the visor, the lens can be framed at least in regions with at least one frame.The visor can have a recess in the region of the nose of the wearer.The visor is preferably made of polycarbonate. However, at least one other material may be used. The visor comprises a preferably impact-resistant and chip-resistant plastic.The visor preferably has at least one coating. The coating preferably, but not exclusively, serves to provide visual protection and / or to avoid condensation. The coating makes the sight insensitive to the UV radiation of the sun.LockingThe visor engages with at least one visor catch on the outer contour of the helmet shell of the sport helmet in receiving catches of the helmet shell.On its outer contour, the sports helmet has at least two receiving catches, in which at least one sighting catch engages.The visor latches in this way with the visor latch in the receiving latch on the outer contour of the sport helmet. The visor is thus fixed in a predetermined holding position relative to the helmet shell of the sport helmet.To close the visor, the visor catch is released from the receiving catch on the outer contour of the helmet shell. The visor is then pulled radially downward on the outer contour of the sport helmet.When pulling down the visor relative to the sport helmet, a visor catch arranged on the visor is fastened to a further receiving catch on the outer contour of the sport helmet.The sight catch arranged on the sight corresponds to the receiving catches which are arranged on the outer contour of the helmet shell of the sport helmet.The corresponding sight catches on the sight and / or the receiving catches arranged on the helmet shell can each be concave and / or convex with respect to one another.An additional embodiment of the invention provides that the visor is arranged resting against the face of the wearer behind an edge on the front side of the sports helmet.The upper edge of the visor of the sport helmet is set back with respect to the edge of the front side of the sport helmet.This positioning of the visor relative to the sport helmet prevents rain water and / or other moisture in particular from dripping from the sport helmet onto the visor and / or onto the face of the wearer of the sport helmet.connecting meansAt least one releasable connecting means is provided on the elastic fastening element for fastening the elastic fastening element to the visor.The connecting means is preferably a thin clip mechanism. The connecting means can also be a thin quick-action closure integrated in the visor.The visor comprises at least one receiving device for receiving the connecting means, which is connected to the fastening element.The connecting means can be detachably connected to the receiving device of the visor.The receiving device of the visor forms a positive connection with the connecting means.The form-fit connection comprises at least two mutually engaging connection partners (connecting means and receiving device).Insofar as and as the connecting means and the receiving device of the visor engage in one another, a positive connection exists between the receiving device and the connecting means of the fastening element.If the mutual engagement between the receiving device of the visor and the connecting means of the fastening element is released, the positive connection between the visor and the fastening element is canceled. The visor can be detached from the sports helmet and can be exchanged for another visor, for example.In order to form a positive connection by the receiving device of the visor and the connecting means of the fastening element, a tongue-and-groove connection or a feather-key connection or a dovetail connection can be used by way of example and not exclusively.It is understood that any other form-fitting connection can be used.The arrangement of the channel in the helmet shell of the sport helmet causes the elastic fastening element to exert a uniform tension on the visor.Further advantageous embodiments of the invention are described with reference to the following drawings and are illustrated in the accompanying drawings.The following are shown: FIG. 1 shows the sport helmet with sight in a front view, FIG. 2 shows the sport helmet with sight in side view, FIG. 3 shows a detail of a visor with a coupling element for receiving the connecting means, FIG. 4 shows the opening on a helmet shell for inserting and removing the fastening element, FIG. 5 shows a detail of a visor and a helmet shell with a catch of the visor, and, FIG. 6 shows the front side of the sport helmet with a receptacle for receiving a catch arranged on the visor.FIG. 1 shows a sports helmet 1 with a helmet shell 2 and a visor 3.On both sides of the visor 3 there are arranged a connecting means 4 each.
