Description

crash helmet

The invention relates to a crash helmet, in particular integral helmet, with an impact-resistant helmet shell, with a Visieröff- coverable by a visor and with at least one ange¬ on the outside of the helmet cal ange¬ associated actuator, with which a remote from the actuating element arranged functional element of the helmet is adjustable by the actuating element is connected to the functional element via a Übertragungsvor¬ direction.

Helmets of this type are known as so-called jet helmets and full-face helmets. Full face helmets have a chin part so that the visor opening is completely enclosed by the helmet cap, whereas with a jet helmet the helmet cap does not extend as such into the chin area under the visor opening.

Integral helmets are known in which the function of a functional element remote from the actuating element can be controlled with an actuating element.

Thus, it is known in an integral helmet, which is formed with a fold-up chin part to lock the chin part in the normal position of use with arranged in the side region of the helmet cap locks, so as to achieve the protection of a one-piece full face helmet. The release of the locks for Zwe-cke of the folding up of the chin part to put on or remove the helmet, takes place by means of a knob which is mounted centrally on the front tip of the chin part, wherein the Dreh¬ movement of the knob pull on two to the both locks running cables, whereby the locks are unlocked. Such a protective helmet is described in DE 40 40 172 A1. It is also known from DE 30 25 920 C2 for an integral helmet of the aforementioned type, with a knob arranged in the same position Dreh¬ flexible cables to operate, which are connected to adjusting the two En¬ the visor and thus opening and closing the visor.

In DE 85 34 132 U1 a full-face helmet is also described, in which the visor can be opened with an elastic element and can be spent on a cable when closing in several locking positions. The operation of the cable is carried out with a slider which is also mounted centrally on the chin part and is displaceable in the vertical direction.

The present invention has for its object to improve the usability of functional elements on a crash helmet.

This object is achieved according to the invention in a crash helmet of the type mentioned at the outset in that the actuating element is arranged on one side of the helmet shell in the region of its lower edge.

The invention is based on the finding that the centrally placed on the chin part an¬ actuators that are designed as a vertically movable slide or knob, at least then are relatively difficult to use by a motorcyclist when the hands of the motorcyclist are protected by gloves. Operating problems also arise when attached to the helmet calotte outside of the chin part sliders, as they are known, for example, for direct control of a rotatably mounted on the inside of the helmet dome sun visor. The laterally behind the end of the visor disc covering the visor disc ange¬ brought slide is intuitively not sure to be taken by the motorcyclist, so that folding down or folding up the sun visor in those cases does not succeed in which a quick operation appears necessary, for example, in a sudden Deterioration of the visibility After using the sun visor (entering a fog bank, in a tunnel or the like) or the reverse transition from darkened visibility to a situation with strong sunlight.

A similar problem arises for setting a vent with arranged on the helmet top sliders that are difficult to feel and operate while driving.

According to the invention, the actuation of such functional elements now takes place in the area of the lower edge on the side of the crash helmet. This arrangement has the advantage that the actuator is intuitively quick and secure to grasp, which was not the case in the conventional sliders, which were mounted laterally behind the visor opening halfway up the crash helmet. In this arrangement, the movement of the actuating element can no longer be transmitted directly to the functional element, which is why the movement of the actuating element is transmitted to the functional element by means of a transmission device. The transmission device serves the purpose of being able to arrange the actuating element at any distance from the functional element. As a result, the transmission device differs from the gearboxes usually used for actuating functional elements, which regularly produce a positive connection via transmission elements between the actuating element and the functional element and thus require a specific proximity of the actuating element to the functional element. A preferred transmission device is flexible and in particular formed by a Bowden cable. In this case, the transfer device for adjusting the functional element is preferably designed in a first direction and in a second, opposite direction, thus serving not only for triggering a function but also for a controlled adjustment in both adjustment directions of the functional element. The improved tangibility of the confirmation element also results from the fact that a good orientation aid is available with the edge of the helmet stands. The region of the lower edge according to the invention which benefits from this extends from the lower edge to a height of approximately 8 cm. In addition to a slider, a pushbutton or a lever mechanism - with or without translation - come into question.

Extensive tests have shown that the arrangement of a Betätigungs¬ element in the side region of the chin part is intuitively best taken, so that a safe and fast operation of the functional elements is possible if this - as in the example of the sun visor - due to the Fahrum- states is required ,

The secure graspability of the actuating element is further enhanced by the fact that the actuating element is formed by a slide running essentially parallel to a lower edge of the helmet dome. This slide is thus displaceable in a substantially horizontal direction, so that it can be formed sufficiently large and with a sufficient displacement travel, since it is not limited spatially to the height of the chin element, as in the known vertical angeord¬ Neten slide is the case.

Preferably, the slider adjoins with its lower edge to the lower edge of the helmet shell or covers the lower edge. This also contributes to the rapid graspability of the actuating element, since the helmet undercut for the helmet wearer can be easily located intuitively. Preferably, the slider is also operable from the underside of the helmet, where it can be provided, for example, with an actuatable from the bottom of the helmet slide button. In general, however, a sliding button attached to the lower edge on the outer surface of the helmet shell can also be operated from the underside. The advantages of the inventive arrangement of the actuating element in the region of the lower edge of the helmet shell also arise when the actuating element is a rotary knob.

The transmission device is preferably designed for direct mechanical transmission of the movement of the actuating element, for which - as mentioned - in particular a Bowden cable is suitable. But there are also other transmission devices conceivable, such as linkage, but in particular also wired or wireless electronic transmissions of the operating movement of the actuating element on the functional element.

The functional element is preferably arranged on the inside of the helmet shell at a distance from the lower edge of the helmet shell, in the case of an integral helmet above a circumferential region of the helmet shell continuing the chin part.

A functional element which is particularly suitable for the actuation according to the invention is a sun visor guided on the inner side of the helmet shell and can be moved into the area of the visor opening. This is preferably connected to the transmission device with two lateral ends. The side ends of the sun visor are preferably mounted in guides that form an arc section. In this case, the curved section has a pivot, which is arranged at a distance from the corresponding side ends of the solar panel. This makes it possible to adapt the movement of the sun visor and its shaping to the curvature of the helmet cap, which requires only minimal space for accommodating the sun visor on the inside of the helmet cap. The fulcrum of the arcuate sections can be fixed if the arcuate section is a segment of a circular arc or, for adaptation to the curvature of the helmet shell, also wandering. Preferred embodiments of the crash helmet according to the invention provide an actuating element, preferably in the form of a slide, laterally on the chin part or laterally in the neck area, ie behind the ear area.

In a particular embodiment of the crash helmet according to the invention, the actuating element is located on a part of the Kinn¬ part forming solid approach the helmet shell, which forms the chin part with a movable, preferably pivoting chin piece. Due to the swiveling chin piece, the slip-in opening of the integral helmet for putting on and taking off the helmet can be enlarged. On the other hand, the fixed approach makes it possible to actuate mechanical connections from the chin part in the manner according to the invention. Preferably, the fixed projection extends over less than half, preferably less than 1/3 of the width of the sighting opening, so that the movable, preferably pivotable chin piece engages significantly more than half the width of the sighting opening, preferably more than two / 3 of the width. The be¬ wegbare, preferably pivoting chin piece is thus asymmetrically auf¬ built and fixed only on one side of the helmet shell, preferably on a hinge.

The invention will be explained in more detail below with reference to exemplary embodiments illustrated in the drawing. Show it:

Figure 10 shows the helmet according to Figure 9 with the sun visor in the folded down state and the vent slide in the open state.

The schematic representation of Figure 1 shows a shock-resistant helmet calotte 1 of an integral helmet, which thus has a chin part 2 and a sighting opening 3 encloses and limits on all sides. In the visor opening 3, a Sonnen¬ aperture 4 is retractable and shown in a fully folded down position in Figure 1. The sun visor 4 covers the visor opening 3 in the usual way only in the upper part, in order to allow downwards a non-darkened view through the visor opening 3.

A visor disc which completely closes the visor opening 3 and is guided on the outside of the helmet cap 1 is not shown for reasons of clarity.

The sun visor 4 has two side ends 5 which are each guided in a guide 6 in the form of an arc section. The movement of the side ends 5 in the guides 6 is controlled by an actuating element 7, which is arranged in the form of a slide in the lateral area of the chin part 2 below the lateral ends of the sighting opening 3. The actuating device 7 is thus located on the chin part 2 below the visor opening 3, but at a clear distance from the front tip of the chin part, which constitutes the middle of the chin part. As is shown in FIG. 1, a transmission device 9 is connected to the actuating device 7. In the exemplary embodiment shown, the transmission device 9 consists of two Bowden cables 10, which are connected with their respective one end to the slider 8 and at the other end to an associated side end 5 of the sun visor 4. As a result of the movement of the slider 8 in one direction, the sun visor 4 is moved from the illustrated lowered position into a high position above the sighting opening 3, while the movement of the slider 8 in the other direction moves the sun visor 4 from the rest position into the position shown in FIG 1 shown folded down ver¬ moves. By a self-locking guide, the sun visor 4 remain in je¬ the intermediate position.

This situation is illustrated again in FIGS. 2 and 3. If the slider 8 is moved completely backwards, the tendons of the two Bowden cables 10 push the sun visor at both ends in the guide upwards into the rest position according to FIG. 2. If, on the other hand, the slider 8 is pushed forward, as shown in FIG. the sunshade 4 is pulled from the rest position according to FIG. 2 into the lowered position according to FIG.

The drawings show that the actuating device 7 is arranged in the illustrated embodiments on the left side of the chin part 2 an¬. The connection from the slide 8 to the left side end 5 of the sun visor 4 thus takes place by means of a Bowden cable 10 guided approximately directly upwards on the inner wall of the helmet shell 1, while the connection to the right side end takes place through a Bowden cable 10 which is located at the lower edge of the Bowden cable 10 Helmkalotte 1 around the neck area is led around on the right side of the helmet shell 1, from there the connection fertil with the right side end 5 of the sun visor 4 produce. The guidance of the sun visor 4 in the guides forming an arc section 6 has the advantage that the pivot point for the movement of the sun screen 4 can be adapted to the curvature of the helmet shell 1 above the visor opening 3, so that the accommodation of the sun visor 4 with a minimal space requirement on the inside of the helmet shell 1 is possible.

In the exemplary embodiment illustrated in FIGS. 1 to 3, the slide 8 can be grasped with a sliding button accessible from the radially outer side of the helmet shell 1. Since the slider 8 is located at the lower edge of the helmet shell, it can also be actuated from diagonally below.

In the embodiment shown in Figure 4, the slider 8 ^{1 is formed} around the lower edge of the helmet shell 1 around, so that its sliding button runs on the bottom and therefore is grippable from below. This point of the integral helmet is easily and safely graspable by the motorcyclist due to its orientation in his field of vision.

FIGS. 5 and 6 show the arrangement according to the invention of the actuating element 7 on an integral helmet which is provided with a fold-up chin piece 11. The chin piece 11 extends over more than 2/3 of the width of the sighting opening 3, which is here closed with a sighting disk 12.

As can be seen from FIG. 6, the chin piece 11 can be folded up by a swivel joint with an approximately horizontal axis arranged on the right side of the helmet shell 1. In the folded-down state according to FIG. 5, the chin piece 11 rests against a fixed projection 14 of the helmet shell 1, here formed integrally with the helmet shell 1, via an abutment edge 13, so that the chin piece 11 forms the chin part 2 together with the fixed projection 14 , Which extends over approximately 1/4 to 1/3 of the width of the sighting opening 3. caking approach 14 carries the actuator 7, which is formed in the illustrated in Figures 1 to 3 form.

FIGS. 5 and 6 show on the left side of the helmet a rotary joint 15 around which only the sighting side 12 can be pivoted. The corresponding (not shown) rotary joint on the right side of the helmet can be formed together for the visor disk 12 and the chin piece 11.

FIGS. 7 and 8 show a further modification of the arrangement according to FIGS. 1 to 3. In addition to the actuating element 7 for the sun visor 4, a further actuating element T is provided, which is e- benfalls formed as a parallel to the lower edge of the chin part 2 movable slide 18, but is arranged above the actuating element 7. The actuating element T is connected to a transmission device 9 'formed by a Bowden cable 10', with which a ventilation slide 16 can be actuated below a ventilation opening 17 arranged in the front region or upper head region of the helmet shell 1.

In the representation of FIG. 7, the slides 8, 18 are in a position displaced to the rear, in which the sun visor 4 is moved into its rest position and the ventilation slide 16 closes the ventilation opening 17.

According to FIG. 8, by sliding the slides 8, 18 forwards, the sun visor 4 connected to the slider 8 moves downwards into the sighting opening 3 and the ventilation slide 16 connected to the slide 18 moves into a position releasing the ventilation opening 17, then that now wind passes through the ventilation opening 17 in the interior of the helmet shell 1, as shown by corresponding arrows in Figure 8 is shown. The embodiment shown in Figures 9 and 10 corresponds to the embodiment of Figures 7 and 8, wherein only the Betätigungs¬ elements 7, T not in the lateral chin area but in the lateral Nacken¬ area, ie in the direction of travel are arranged slightly behind the area of the helmet shell 1 covering the ears of the helmet wearer. By shifting the slides 8, 18 backwards, the sun visor 4 can be moved downwards and the ventilation opening 17 can be released with the ventilation slide 16.

Of course, further functional elements are conceivable which can be actuated advantageously by actuation elements 7, T arranged according to the invention in the region of the lower edge of the helmet shell 1.
