Description

  The present invention relates to a protective helmet for protecting the head of a driver who drives a vehicle such as a bicycle such as a bicycle and a motorcycle, a water bike, and a snowmobile.

  When driving vehicles such as bicycles and motorcycles, water motorcycles, and snowmobiles, the driver usually wears a protective helmet in case of an accident. Many of the protective helmets are configured to cover most of the head with the helmet body, so the head is properly protected in the event of an accident, resulting in a reduction in mortality at the time of the accident. Has been expected.

  However, if the helmet body covers most of the head, the helmet-equipped vehicle has a disadvantage that it is difficult to visually recognize the surroundings (particularly the rear). When the helmet is worn, the field of view becomes narrow, and there are also inconveniences that it is difficult to perform a look-back operation for viewing the back.

  Therefore, conventionally, protective helmets equipped with a helmet display that displays an image of the rear of the helmet wearer in front of the helmet wearer have appeared. Among the prior arts related to such a helmet display, there are a right display unit that displays a right-and-left reverse image on the right side of the helmet wearer, and a helmet mount on the left side of the helmet wearer. There is a helmet display that includes a left display unit that displays an image of the left rear side of the person in a reversed manner (see, for example, Patent Document 1).

  And according to such conventional technology, it is possible to clearly distinguish the right rear image and the left rear image of the helmet wearer, and it is possible to know the rear situation without looking back, and safety It was supposed to be able to increase.

  However, in the above-described prior art, the rear state is easily grasped by the helmet display, but in fact, it is not easy to grasp the display content of the helmet display instantaneously during driving. In particular, since the viewpoint of a helmet wearer is usually placed at a distance, it takes a considerable amount of familiarity to move the viewpoint to a nearby helmet display for safety confirmation.

  An object of the present invention is to provide a protective helmet that allows a helmet wearer to easily check safety without requiring skill.

  The protective helmet according to the present invention is configured to protect the head of the helmet wearer. This protective helmet includes at least a helmet body configured to cover the head of the helmet wearer and a visor provided on the helmet body so as to be freely opened and closed.

  The helmet body includes an audio output unit that outputs audio information to the helmet wearer. Examples of audio information include, but are not limited to, navigation information, alert information for notifying the approach of a vehicle or a pedestrian, entertainment voice from a radio or music player, and the like. In addition, although a normal speaker can be used as the audio output unit, an earphone having a noise canceling function or a bone conduction function may be arranged to fit the wearer's ear.

  The visor includes display means for outputting visual information to the helmet wearer. This visor is preferably constituted by a transparent member. Moreover, it is preferable that a display means is a transparent flexible flat panel display affixed on the visor via the transparent adhesive. Typical examples of the display means include a flat panel display such as a liquid crystal display and an organic EL display. It is preferable that the flat panel display has transparency and bendable. By using a resin substrate such as polyimide or using a glass substrate thinned by etching to about 0.05 mm to 0.20 mm, it is possible to obtain a flat panel display that is curved along the curved surface of the visor. . The flat panel display is preferably attached to the visor with a transparent adhesive, but is not limited to this configuration.

  It is preferable that the above-described protective helmet further includes imaging means capable of photographing at least the rear of the helmet wearer, and the display means displays photographing information of the imaging means at least while the audio output unit is operating. When the helmet wearer is listening to the sound from the sound output unit, it may be difficult to hear the surrounding sound. At that time, the display means displays the image of the back, etc. This makes it easier to grasp the situation and prevents a decrease in safety.

  Further, the display means includes a plurality of display units respectively arranged on the left and right sides of the visor, and selectively operates the left display unit or the right display unit according to the visual information to be provided to the helmet wearer. It is preferable. For example, by alerting the right display when the vehicle or pedestrian is present on the right side, while the left display is illuminated when the vehicle or pedestrian is present on the left side, Crisis avoidance behavior can be taken quickly without looking at the display on the display unit in detail. Further, in the case of left turn guidance, the left side display can be illuminated.

  For example, in the case where it is difficult to focus on the display means or to switch the perspective of the visual field by providing the alert and guidance information by voice and using the display of the display means in an auxiliary manner, for example, The helmet wearer can easily check the safety.

  According to this invention, the helmet wearer can easily confirm safety without requiring skill.
