Definitions
- the present invention relates to a device enabling the visor of an integral helmet to be actuated via a movable part of the face or the tongue.
- the full-face helmet generally has a protective element for the lower part of the face defining an opening capable of being closed by a visor which can be moved manually.
- This provision obliges the biker to let go of the handlebars of the motorcycle with one hand and to blindly recognize a mark or the edge of this visor to raise or lower it.
- Known solutions consist of motorized systems on racks or the like, powered by a source and making it possible to move the visor. These systems are actuated by controls comprising either an electrical contact on the helmet itself, which requires in the same way to put your hand on the helmet, or a remote contact with a wire, or finally a contact with the handlebars a remote control.
- the plate is mounted behind a network of orifices and perpendicular to the air flow blown by the carrier and capable of passing through these orifices.
- the pressure resulting from the helmet holder's breath is used to move the plate, which then touches the contactor by closing the electrical circuit.
- the device according to the invention makes it possible to solve these technical problems in a satisfactory manner.
- a device for actuating an integral helmet visor characterized in that it comprises, on the one hand, a motorization system powered by an electric source and making it possible to move said visor between an open position and a closed position, and on the other hand, an electronic control circuit inside the helmet and associated with said motorization system and which is capable of being activated by electrical connection of a part of the face or of the tongue with at least one electrode connected to said circuit.
- the device comprises at least two electrodes with high impedance and low current, capable of being short-circuited by direct contact with the tongue.
- the device comprises a right electrode, a left electrode and a central electrode connected to the ground of the circuit.
- the device comprises at least one free electrode connected, on the one hand, to a capacitor of the control circuit and intended to be connected, on the other hand, to a mobile part of the face or to the tongue by direct electrical contact or electrostatic influence producing a capacitive effect.
- the device comprises two free electrodes corresponding respectively to the raising and lowering of the visor.
- said control circuit is connected to the motorization system via CMOS inverter amplifiers in series and transistors connected in bridge.
- the electrical source is integrated in the lining material of the helmet.
- said electrode is arranged in the protective element opposite the mouth.
- control is done by a movable part of the face or the tongue.
- control is therefore activated by two electrodes with high impedance and low current right and left short-circuited for opening and closing the visor or two right and left electrodes with capacitive effect for opening or closing the visor.
- the electronic circuit can be mounted on the input of CMOS inverters in saturated series amplifier or one or the other of two transistors mounted in bridge.
- All of the cells or batteries forming the electrical source are buried in the foam of the helmet.
- FIG. 1 shows a horizontal sectional view at the level of the chin protection element of an integral helmet equipped with a first embodiment of the device of the invention
- FIG. 2 shows a horizontal sectional view at the chin element of an integral helmet equipped with a second embodiment of the device of the invention
- FIG. 3 shows an electronic control circuit capable of being used for the first embodiment of the device of the invention
- FIG. 4A and 4B show two variants, of a part of an electronic control circuit capable of being used for the second embodiment of the device of the invention.
- the helmet shown in FIGS. 1 and 2 is an integral helmet provided on the front with an element 1 for protecting the lower part of the face and in particular the chin.
- the protective element 1 consists of a curvilinear profile generally disposed a short distance from the mouth and delimiting downward an opening or window capable of being closed by a visor (not shown).
- the device of the invention is intended for actuating this visor.
- a motorization system M powered by an electrical source (battery, batteries, etc.) B (see FIG. 3) making it possible to move the visor between a high open position and a low closed position of the window.
- the motorization system M and the electrical source B are integrated into the lining material (foam, etc.) of the rigid shell forming the structure of the helmet and are therefore not visible, which preserves the overall aesthetic appearance.
- the motorization system M is coupled to an electronic control circuit C also mounted inside the helmet shell.
- the control circuit C is activated by electrical connection of a mobile part of the face (chin, lips, etc.) or of the tongue with at least one electrode 2, connected to said circuit and disposed in the protective element 1 located at opposite the mouth.
- the device of the invention comprises three electrodes 2a, 2b, 2c with high impedance and low current.
- the extreme electrodes 2a, 2c are thus likely to be short-circuited by direct contact, for example with the tongue L of the wearer of the helmet while the central electrode 2b is connected to the ground of the circuit.
- Closing the circuit C leads to the power supply to the motorization system M and the displacement of the visor by passing through the tissues of the tongue a very weak direct electric current.
- the device comprises at least one, and here two, free electrodes 2a, 2b each connected, on the one hand, to a capacitor K of the control circuit C and intended to be connected, d on the other hand, to a moving part of the face or to the tongue L by direct electrical contact or electrostatic influence by producing a capacitive effect.
- the two electrodes 2a, 2b respectively correspond to the raising and lowering of the helmet visor.
- the electrode is said to be "in the air” and the capacitor K does not deliver any current in the absence of any electrical coupling of the electrode with another conducting element.
- Any isolated conductive mass such as that of the human body can be considered as an electron reservoir capable of ensuring, by contact with an electrode which is in the air and even by simple
- Electrostatic "influence” means a current leakage through the capacitor to which this ground is connected.
- FIGS. 4A and 4B represent two variants of electronic assemblies intended for use in a control circuit in capacitive mode.
- FIG. 4B uses the principle of the critical detuning of an oscillating circuit.
- the motorization system M is triggered by damping an oscillation due to a change in frequency of the alternating current.
- This change in frequency is generated by connection to the oscillating circuit of an additional electrical capacity formed here by the human body.
