Description

The invention relates to a full-face motorcycle helmet in which the helmet visor can be opened or closed from the handlebar grip using a switchable electromagnetic pulse generator. This is achieved by an electromechanical visor raising/lowering mechanism arranged within the rear area of the helmet, which is set in motion by a receiver module that is also integrated via a downstream electric motor that can be operated birotatically.

The necessary electronic components, which consist of battery network, switching module, main and limit switches and the drive motor, are conveniently installed in the lower rear part of the helmet shell, in a specially designed bulge to the required size, with the purely mechanical part such as the lever drive (visor rotating bracket, deflection lever, etc.) extending within the subsequent upper area of the helmet shell. This lever drive is moved in both directions by the drive motor via a toothed thrust segment via two gear reduction stages.

Until the torque delivered by the Egr; motor definitely reaches the visor rotation axis, the speed of the motor is reduced to a passable lifting speed of the visor via several specific rotation and lever dynamic reduction stages. In addition, the angular positions of the lever joints in relation to one another, in accordance with the individual toothing engagements of the gear drive in the rest position as well as engine standstill, etc., ensure that the visor is locked in any position in a way that is resistant to the wind. The power supply of the transmitter module is ensured by the on-board power supply after the respective motorcycle has been started up, whereby the final visor lift is also carried out by a

Battery network is operated, the capacity of which can be regenerated on the one hand by charging current from the motorcycle battery - when charging in the garage and on the other hand while driving - by additional solar cells installed on the helmet shell.

The transmission and reception of the electromagnetic switching pulse is amplified by two separately functioning antenna stages, the position and shape of which are individually dimensioned in a suitable manner (when using wire antennas).

The handlebar grip compact switch is operated using a push or slide switch above the integrated transmitter module and is also conveniently positioned.

Since the low power transmission torque of this visor lift does not require any heavy transmission elements and the electrical elements as well as the required mounting and guide struts are also lightweight, this new helmet should hardly noticeably reduce comfort due to its small weight increase. In general, this induced visor lift mechanism enables riders of heavy motorcycles in particular to always maintain contact with the handlebars with both hands, which has a positive effect on driving safety.

The functional and elementary explanation is based on the drawings according to the function and structure of the invention shown.

Explanation of drawing "1

This drawing shows the handlebar grip compact switch, which has been specially redesigned for the transmitter function of this vertical electromechanical visor lift - purely externally, as well as the elementary structure of this specifically modified motorcycle helmet required for this function - visible here in the helmet cross-section.

This shows that the compact switch on the (e.g.) right handlebar grip also has a flexible wire antenna and two pressure switches located directly next to the throttle roller, which are intended to operate the transmitter module installed inside the lower housing casing. The vertically running wire antenna leading out of this housing casing is clamped in or fixed in place in the upper part of the compact switch in a suitable manner so that frequency oscillations in this area are largely avoided. This compact switch, which also functions as a transmitter, could correspond to the overall design shown here as an example if it is equipped with these transmitter elements on the throttle side.

The order and in some cases the function of these individual electronic or mechanical visor lifting elements, which are visible here from a sectional perspective, are shown, and are referred to in more detail in the following drawings. As this entire visor lifting device extends within the rear part of the helmet between the helmet shell and the lining, a

- 1/2 -

A slight curvature is required, which corresponds to minimal dimensions when the electronic elements located there are arranged rationally.

The cavity in the upper area is necessary due to the lever-mechanical deflection of the visor swivel bracket and at the same time integrates the swivel range of the same.

The overall wearing comfort is not negatively affected by this technical addition to the padding.

This drawing explains the detailed, elementary structure of this new full-face motorcycle helmet, shown here from a longitudinal section perspective, according to the respective number assignment.

= helmet shell

= synthetic fibre foam

= padding of the helmet shell divided into segments

= Helmet visor, which is hinged on both sides to the visor swivel bracket and has a specially reinforced emergency opening segment on its lower edge

= Cavity which integrates the dynamic deflection lever drive and, with the addition of small tolerances - the same size as the swivel range of the visor swivel bracket, extends within the helmet shell and a separate plastic casing

= Visor swivel bracket, which is adapted in terms of its shape to the radial extension of the helmet shell running parallel to its swivel range and is connected by means of a specific arrangement of securing elements, on the one hand firmly to the visor on both sides and on the other hand by a sliding joint connection to the deflection mechanism

= a pivoting lever mounted off-axis on the helmet shell, which uses two specifically dimensioned slotted joints to control the vertical movements

= Mounting of the bell crank on a protruding bolt stump on the helmet shell, which must be secured in a suitable manner (e.g. using a cotter pin) like the other joints

= flexible thrust segment, which is moved vertically by the drive motor via the reduction gear within two guide components connected to each other and to the helmet shell, due to its one-sided toothing, and in doing so sets the visor lifting mechanism in motion via the top-hinged reversing lever, or switches it off automatically at the visor limit/stop position using two specially offset stop bolts, which are moved within two guide tracks in both directions to the respective limit switches

= Wire antenna of the receiver module, which is laid below the helmet lining in this exemplary position, or passes through the helmet shell from the inside to the outside and is held close to the helmet body on the outer side of the helmet shell by means of a clamp at approximately the same height, since protruding from it could endanger the eyesight of the passenger

= Battery housing, which is designed to accommodate, for example, four AA batteries of 1.5 volts each, the capacity of which can be supplemented by a charging socket (not visible here) or switched on or off from the operating network using a suitable switching bridge; furthermore, its screw connections with the two switching module mounting claws serve to securely lock the switching module to the guide of the thrust segment, which is also stiffened by this, since the outer mounting claw holder is also part of the helmet shell.

For a spatial representation of all the mechanical and electronic components of this helmet, please refer to Drawings 4 and 5.

Explanation of drawing "3

In this drawing, all elements in motion when the sight is activated are shown with respect to the curved or circular directional paths they take by means of arrow lines running parallel to them, which are designated ex, β as well as ¹ x, y and ζ.

The circular arrow lines "x" and "y" represent the direction-changing direction of rotation that the two elements in engagement: motor output gear and reduction gear, take in relation to each other, whereby the direction of rotation "y" is definitely converted into the curved direction of movement "ex." by the thrust segment that is also in engagement. This direction of movement "ex." is in turn kinematically converted by the radial deflection mechanism "z", which is characterized by two specific long-link joints, resulting in the visor swivel movement "β" in the same direction. The black arrow sections represent the directions of movement of these respective associated elements, which they take when the visor is opened and vice versa. This kinematics, shown in arrow lines, makes it clear that the torque indicated by the drive motor via the reduction gear is first transposed into several lever-dynamic direction-changing movements before it efficiently causes the lift of the visor, which results in the aforementioned wind-resistant locking of the visor in any position.

- 4/1 -

Explanation of drawing "4"

This oblique perspective shows the positional arrangement as well as the proportional dimensions of all the components integrated into the helmet shell and belonging to the visor lifting mechanism, the lever drive geometry of which must be specifically parallelized to the spherical shape of the helmet shell. Furthermore, the reversing directions of movement of the lever mechanism can be seen here, the kinematic deflections of which, starting from the thrust segment, are each illustrated by segmented arrow lines arranged parallel to them. The white arrow sections represent the radial directions of movement that the associated lever elements or their joint connections take when the visor is closed and vice versa. The limit positions of these lever elements and their ongoing lever dynamic transposition are marked by the two continuous dash-dot-dot lines, the origin of which - oc , is the radius of movement of the thrust segment acting as the drive element. This vertical drive is transferred to the radial-axial output of the visor swivel bracket by means of two specifically dimensioned slotted slideways of the deflection mechanism, so that the latter travels twice the radial distance compared to the thrust segment due to the off-axis mounted deflection lever, which is necessary due to the thrust segment being kept as short as possible in terms of height and resistance to bending. Furthermore, this view shows the fastening points or locks which these individual

- 4/2 -

mechanical and electronic components are connected to the helmet shell and coexist with each other, whereby the specific positioning of the lever joints and their individual dimensions are determined in accordance with the speed/transmission ratio of the electronic drive unit and its limit switch by mathematically formulatable relationships in relation to individual visor travel.

- 5/1 -

Explanation of drawing "5 '

In this drawing, all elements of the sight lift kinematics are shown in the views required for detailed explanation within separate drawing field sections.

Field 1: Here the helmet visor can be seen from an oblique perspective, which shows that both locking and guide ends are each centered by equally sized square recesses. These are required for the purpose of locking on both sides in a way that is resistant to twisting on the corresponding square mounts of the visor swivel bracket. Since this moment of force emanating from the visor swivel bracket always acts on the visor swivel axis, the visor must be specifically reinforced or guided at these points. This is achieved on the visor itself by the two plastic guide bushings shown here, which are either glued or pressed in and thus reinforce the relatively thin-walled Plexiglas sufficiently to ensure it is break-resistant.

Regarding field 2: Within this drawing section, the visor swivel bracket is shown in the front view, as well as its helmet- or visor-side guide/locking elements, as they are positioned or assembled in the order in which they are placed, in the side view and in another suitable perspective form.

- 5/2 -

This perspective once again illustrates the circular segmental shape of the bracket itself, which must be precisely adapted to the spherical dimensions of the helmet shell body, so that a sufficiently space-saving integration of the same within its swivel range is guaranteed.

Furthermore, this view shows the axial course of both guide ends, which serve on the one hand to axially guide the bracket within the helmet shell wall and on the other hand to hold or lock the statically pivoted helmet visor. The guidance within the helmet shell wall is implemented on the bracket side by means of plate-shaped sliding segments and on the helmet shell side by means of almost equally sized recesses. The precise elementary explanation of all the guide/locking elements shown here is given in the order from the inside to the outside or v. 1. nr.

are circular in cross-section and consist of one piece with the plastic material of the bracket; serve as an axially rotatable locking or bearing of the bracket within the symmetrically assigned bearing recesses on both sides of the helmet shell wall (see drawing 4)

- 10 -

- 5/3 -

Square holderK

are square in cross-section and are also a component of the bracket; they act as axial drivers for the helmet visor, which is simultaneously locked in place, and are also used to accommodate various safety elements.

Washers for the sliding segments:

made of metal or plastic; are designed as perforated discs, the inner and outer diameters of which are equal in radial direction to the square mount or to the sliding segment and are intended for the purpose of clamp-free axial integrity or storage of the sliding segments within the helmet shell storage recesses

Storage conditions of the helmet shell wall

serve as an integrated bearing for the sliding segments of the visor swivel bracket, which can be rotated within them and are congruent with the sliding segments in terms of their radial extension (apart from the required clearance tolerances), so that the bracket itself does not come into contact with the washers in any way.

Since the helmet shell wall is sealed to the outside by means of rotatable sealing discs and this also requires radial bearing cutouts, the same must, as

- 11 -

- 5/4 -

As can be seen from the sectional view, they should be slightly widened at these points.

The hole connecting the two bearing cutouts is dimensioned to be equal to the maximum cross-section of the bracket’s square drivers arranged centrally therein, plus a mandatory clearance tolerance.

Rotatable locking sealing discs^

made of metal or plastic, are designed to be radially movable within the bearing cutouts of the helmet shell wall, which are of the same diameter, for the purpose of internal sealing of the helmet shell body and also serve as integral contact surfaces for the safety clips of the bracket.

As can be seen from the upper front view "a", this is achieved by a central square recess that corresponds to the dimensions of the driver profile, as well as by means of a one-sided hollow that is the same size as the safety clip, which definitely provides a flat contact surface for the respective sight guide bushings.

Safety clasps:

consisting of spring steel, are mounted within the respective receiving grooves of the square driver and thus secure the bracket separately in its bearing seat within

- 12 -

- 5/5 -

the helmet shell wall.
The exemplary shape of the same could correspond to the front view "a" above.

Plexiglass wall of the helmet visor2

is identical to conventional helmet visors in terms of its material structure, but has reinforced guide bushings on its locking legs, which are glued or pressed into the circular section of the visor wall, which can be seen here in the sectional perspective

Plastic guide bushings of the helmet visor:

are torsion-resistant and are incorporated into the hole mounts of both visor locking arms and, with their centric square recesses, serve to axially transpose the swivel moments of the bracket onto the helmet visor

They have circular recesses on their outside, which serve to lock the safety spring they contain. They also have conventional markings on the outer edges, which are intended to provide optical support when releasing or locking the safety cap.

- 13 -

- 5/6 -

Safety spring^

- are designed as short, low-pressure helical compression springs with a small spring stroke, whose task is to lock the respective safety cap in its locking position by applying pressure, or to ensure the release process by pressing it in.

Fuse box^

- are used to lock the locking mechanism on the two square drivers of the bracket using specifically profiled retractable locking cams, which are inserted into the homologously dimensioned recesses in the driver ends and are locked or unlocked when turned by 90°

This is achieved on the one hand by the safety spring and on the other hand by means of a locking mechanism within the wall of the driver ends shown above. This upper view once again shows the respective outline of the helmet shell bearing recesses, the sliding segment included together with the bracket and its cavity are shown distinctively darkened here.

Field 3: Here the specifically shaped bellcrank is shown extensively using various views or partial views.

- 14 -

- 5/7 -

This results in its radially curved shape on both sides, the dimensions of which are based on the required parallelism to the helmet shell wall, as well as on a preservative resistance to bending. Due to its off-axis positioned bearing bush, this reversing lever kinematically converts the permanent vertical movements of the thrust segment, which is articulated on the slot side, into axial movements at a progressive transmission ratio of approx. 1:3.4 1:4.6.

Rotational movements of the visor swivel bracket hinged on the other side.

The partial views, which are assigned according to the installation sequence, show in detail the basic composition of the linkage on the bracket side using a rivet bolt lock, as well as the pin-secured mounting of the lever itself on a bolt projection on the helmet shell wall. The washers, which are obligatory in order to prevent a negative clamping effect, are shown in a distinctively darkened manner.

Regarding field 4: Within this section of the symbol, all electromechanical switching or structural units which are integrated within the helmet shell are shown in the views required for clear graphic explanation, which are taken into account in detail below from left to right.

- 15 -

- 5/8 -

Battery case^

consisting of thin-walled plastic, is designed to accommodate four 1.5 volt mignon cells in one plane and is locked or arranged using two retractable slotted head screws below the receiver module

This battery housing also has the contact plates required for parallel battery connection, two of which also function as connection poles. In addition, the capacitive on/off switch on the one hand and the charging socket on the other hand are secured by means of protruding screw hole eyelets on the right and left flanking sides of this housing. The hinged cover is attached to a hole in the helmet shell wall using a suitable hooking tip, which provides additional anti-vibration reinforcement, which definitely protects the switching module from external influences due to this cover-side overlap.

is intended for the integrative locking of the drive motor

This two-part crimp head mount is (apart from the screwed-on clamp) a part of the helmet shell body or

- 16 -

- 5/9 -

made from one piece, whereby the vibration-related oscillations of the included ε-motor are absorbed by the entire spherical shell of the helmet and thus sufficiently minimized.

radial dynamic drive of the thrust segment^'

takes place from the gear-armored armature of the drive motor via the downstream reduction gear, through which the radial dynamic circumferential moments of these gears are transposed to the thrust segment which is thereby moved vertically.
The drive speed of the motor (approx. 1200 rpm) is restricted in the possible reduction ratio of 1:2.7 to 1:3.5, which in conjunction with the specific lever drive geometry ensures an acceptable lifting speed of the helmet visor.

Guide sheath of the thrust segment:

is intended for the integrated guidance of the thrust segment and at the same time serves, by means of special reinforcements, for the axial locking of the reduction gear and for holding the module board. This guide sheath is attached to the helmet body at the top by two self-locking locking bolts that are part of the helmet shell wall and can be segmented lengthwise by means of three snap-in eyelets (see sectional view "A"), which is due to the switching

- 17 -

- 5/10 -

pins of the integrated thrust segment necessary.

The rectangular guideway is dimensioned to match the cross-section of the thrust segment guided in it, plus a required clearance tolerance, which results in smooth sliding. The alternately curved shape takes into account the feeding process in the lower area, and the parallelization of the emerging thrust segment to the helmet shell wall in the upper area, which must therefore be made of permanently flexible plastic. One of the two guide halves is provided on the outside with a bifunctional limit switch for the purpose of a motor limit switch, along with two specifically dimensioned guideways, which, in conjunction with the two switching pins of the thrust segment guided or acted upon in it, control the reversible power supply of the drive motor in the sight limit/stop position or, in these positions, direct it to the LED negative pole of the module board.

This is ensured by the proportional extensions of both guideways to the maximum sight stroke, through which the respective switching pin approaching the limit switch can definitely act on a spring-loaded contact plate, which is subsequently bridged by two

- 18 -

- 5/11 -

Contact lugs (see also the twice enlarged sectional, top view or front view illustration "B") form a cable bridge between the respective motor contact and the circuit board LED(-).

As a result of this current flow, the drive motor can no longer be controlled in the direction of rotation that has been stopped as long as this contact bridge is not released again by moving the thrust segment in the opposite direction using the motor rotation direction that is still operable or controllable. The respective contact plate springs and the contact lugs, which are offset diagonally in pairs (which is necessary due to the mandatory solder joint separation here), are shown distinctively darkened due to their metal content compared to the plastic structure of the switch base plate (see complexion "B"), which is an integral part of the similarly structured guide sheath.
The return springs must be locked or fastened on their outer pressure flanks in a way that is sufficiently resistant to loosening. Using the two radial circumferential limit lines, the possible positioning of the driving or driven gear tooth flank ring can be determined from the switch-side view, which shows, among other things, the decimated tooth flank engagement in the slideway or driver toothing of the thrust segment.

- 19 -

- 5/12 -

Thrust segment: - is made of permanently twistable plastic

consisting of, intended for the vertical transmission of the tooth flank circumferential forces of the one-sidedly engaging reduction gear to the sight actuation lever drive and controls the drive motor limit switch by means of two specifically offset switching pins depending on the two sight limit/stop positions.

The length of the permanent drive teeth is proportional to the individual bell crank ratio or to the definitive sighting path.
The reversing lever, which is hinged on the 1-hole side, is locked to the joint bushing of this thrust segment in a conformal manner (apart from an individual rivet end) as with its bracket-side hinge by an aluminum rivet bolt, which makes lubricants or separate locking elements unnecessary, which facilitates maintenance.

Explanation of drawing supplement "5A"

Using these offset helmet perspectives in the respective side or transparent view, the possible positional locking of the receiver board or antenna on both sides of the helmet shell wall can be seen.

From this we can once again conclude that this wire antenna, which is installed using a screw connection, runs parallel inside and outside, which requires the clamping eyelet shown here on the one hand and a breakthrough seal in the form of a flanged rubber sleeve on the other. Regarding the locking claws on the module board, it should be noted that these can also be arranged diagonally opposite one another.

However, in the case of a linear-central assignment, as in this example, the claws on the helmet side must be measured according to the adjacent plate width in relation to sufficient seating stability.

He 1 comment on drawing "6'

Using this drawing or detailed views, all control/operating elements integrated in the handlebar grip compact switch, based on which the helmet-side circuit board can be electromagnetically pulsed in two phases, are shown in the perspectives required for precise explanation, which are now described from top to bottom.

Transmission frequency gain:

- can be done either by a wire antenna - as here, which emerges or branches off from the module housing upwards, or by means of an infrared diode, which are each directly or indirectly connected to the relevant soldering point on the module board (Pl-S). The wire antenna would probably be more advisable here, as it is positioned on the clamp head side, protruding over the compact switch by about this amount, and can normally hardly collide with the operator's hand or be covered, which would result in pulse restrictions in the case of an infrared window. In addition, the frequency stability of external antennas, provided they are locked in place to prevent vibrations, as is the case here, for example by means of a clamp, is given in a wider directional field.

The spring coil positioned above the clamping eyelet also ensures sufficient spring-elastic fracture stability of the antenna.

If, for whatever reason, the transmission frequency is activated by means of an infrared diode, then this is, as shown in the example above,

- 22 -

- 6/2 -

It is recommended to install it below an infrared window that is adapted to the respective upper combination switch shape, in such a way that the driver's head or helmet area extends within the emitted transmission beam angle.

The two diode connections must be extended accordingly due to the distance to the module board, which extends in the height of the compact switch.

Control keyboard:

- is either designed as a reversible slide switch with a vertical switching direction, as in the case of conventional remote controls of various toy items, or, as is evident from this compatible overall design of the entire compact switch keyboard, in the form of two push buttons separated from the respective sight stroke direction, whereby the latter is described in detail below using two functional views offset in perspective, in view of the higher probability of implementation with regard to the elementary mechanical breakdown. As these detailed views illustrate, the contact fields of the rear module board (Pl-S = board-transmitter module) are bridged by a reset-loaded pressure switch rod for each motor rotation or sight stroke direction, by means of two contact eyes placed in the direction of actuation, the parallel or diagonal lateral offset of which, with conventionally positioned contact fields, extends according to the restrictive dash-dot-dot line of the lower left rear board view, from which the cross-sectional dimensions of the various

- 23 -

- 6/3 ^years -

profiled eyelet holders and their guide bolts are shown to scale.

The return springs as well as the fork joint bolts are shown distinctively darkened due to their metal content.

Furthermore, any black or white arrows in this drawing correspond to the color-coded sighting stroke directions of previous kinematic representations.

integrative installation:

As can be seen here from an exploded view of the switch module integration to a vertical fictitious level, the integrated locking of the horizontally positioned module is provided by, for example, three continuous screw connections, with a centered profile seal protecting this circuit board on the housing side against external influences. If one or the other manufacturer considers the keyboard to be by means of a reversible slide switch (see enlarged front view on the left and the top view below of the switch slide guided by it) to be right or cheap, the module board must be installed vertically within the compact switch housing in a suitable manner due to a switching direction that is the same as the sight kinematics, as shown schematically on the left.

Furthermore, due to the predominant motorcycle electrical system voltage of 12 volts, a module-based regulation in the form of a voltage converter to the capacitive voltage value of 9 volts corresponding to this exemplary transmitter module is necessary, which in this case

- 24 -

- 6/4 "-

must be connected in a suitable manner to the power supply (terminal 15). The switching element structure of this converter version that comes into operation here can be seen by looking at the lower right-hand figure, although it would be advisable to make the integrity of such a separate voltage converter unnecessary by means of module-side capacitive on-board power supply synchronization.

Explanation of drawing "7 '

In this drawing, the transmitter module on the left and the helmet-side receiver module on the right are shown from the perspective that allows the specific circuit board components to be defined and viewed to a sufficient extent.

Since an individual reference to the respective integrated electronic switching or component elements, which are essentially divided into transistors, magnetic coils, blocking/capacitance diodes, electrolytic or disc capacitors as well as the obligatory IC ¹ S and low-resistance resistors, does not correspond to a system description that focuses on the essentials, only the electronic values or designations are assigned to these module elements by means of suitable indication, through which the elementary functionality can be localized as far as possible with expert insight in connection with the following system circuit diagrams. The coded circuit board designations added at the top left are dedicated to the manufacturer-specific breakdown of the modules that also serve this system, which, as already mentioned, come from conventional toy remote controls.

Explanation of drawing "8 '

These two specific system circuit diagrams show the circuit integration of the module boards shown here in the rear view, whereby the symbolic designation "Pl-S" stands for the module board that is electromagnetically activated or operated on the compact switch side in the transmitting function, and "Pl-E" stands for the electromagnetically reactive module board installed on the helmet side, which induces the definitely required visor stroke via a bifunctional switching stage and an electric motor controlled by it.

With regard to the elementary symbols, circuit symbols, terminal designations, current-voltage or capacitance values and the intermediate supply line/contact connections in the respective standardized dimensions, the bi-/unipolar switching or circuit board functionality of this compatible switching system can be generally determined with expert insight and taking into account the criteria listed below.

Assuming internal knowledge of all the electromechanical effects explained above, the minor criteria and graphical features can now be plausibly understood using the following separate detailed descriptions. First of all, there are the respective arrow sections, which represent the corresponding actuation or switching direction in a color that is comparable to the previous drawings, and

- 27 -

thus also marking the same direction of sight lift. Furthermore, with regard to the bipolar on/off switch, which is also marked in the operating directions, it should be noted that when it is switched off (operating direction is the same as the white arrow section), it bridges an additional charging socket installed on the side of the battery box with the corresponding battery mains connection, so that when Ni-Cad batteries are used, their capacity can always be recharged using a specific charging cable.

For the sake of convenience, this charging cable should find its capacitive connection within the respective motorcycle network so that any additional charging can be carried out completely independently of location.

Of course, a specific voltage/current converter would have to be connected upstream of this mains connection to take into account a reasonable charging capacity. Since motorcyclists usually ride in sunshine, the helmet shell could, using this fact, have a specifically dimensioned solar generator on its upper rear area (see drawing 4), which, with an optimized photovoltaic effect, should roughly correspond to the charging powers specified here.

To ensure that the storage capacity is not decimated again by this module in the dark or when there is too little light, a compatible Schottky diode - or better still - a suitable charge protection module must be connected downstream.

- 28 -

Finally, the interference suppression capacitor should be mentioned, which is particularly necessary when operating this system in radio helmets and, as can be seen, must be connected between the two connecting poles of the drive motor. This interference suppression element should correspond to the capacitive values specified here if sufficiently intensified.

- 29 -

Explanation of drawing "9

According to these definitive drawings, the two charging versions of the recommended Ni-Cad batteries integrated into the helmet are shown graphically again separately, through which, as already explained, the required charging currents are injected both via a charging cable from the motorcycle's operating network and by means of a solar cell module added externally in the upper rear area of the helmet shell sphere. The possible positioning or extent of this solar cell module is distinctively obscured in the side view and shown linearly outlined in the top view next to it, from which a passable arrangement and dimension of this element can be derived that takes the required aesthetics into account and which, in this scaled extension, should provide the specified charging values with sufficient solar radiation intensification. Referring to the figure below, the circuit integration of a compatible charging protection module instead of a conventional Schottky diode into the power supply line can be seen, which probably most effectively preserves the capacity of the battery network against reversible discharge.

Furthermore, the inner guidance of the helmet visor shown here could also be implemented with this system by constructing specific linkages or locks on the visor swivel bracket, which would certainly also benefit the overall design of this

Neo motorcycle full-face helmet. It should definitely be noted that two specific pulse generator elements, each electromagnetically controlled in parallel, could also be integrated into the corresponding conductor tracks of Pl-S, which, when the power supply to Pl-E (which must also be additionally equipped or interposed in a compatible manner) is switched on or off, or when the ignition system is switched on/off, open the helmet visor by approx. 1-2 cm (with "Ignition") via two restrictive motor stages induced by this on the one hand and close it completely via the limit switch elements when driving is stopped.

These circuit effects would thus spare the motorcyclist the obligatory, rectified manual controls.
