Description

  The present invention relates to a safety helmet provided with an ear protector.

  Ear protectors make the ears warm, but have the disadvantage that they cannot perceive the surrounding sound, or at least not satisfactorily. Therefore, a helmet including an ear protector that can be removed according to an external temperature is known.

  However, in many sports, especially winter sports, this is often not possible. Ear protectors are also adapted to the average anatomical features of winter sports users, so they often do not completely cover the ears when the ears are located in different positions and sizes. Optimal protection against low temperatures is not guaranteed.

  Accordingly, it is an object of the present invention to provide a helmet with an ear protector that provides optimal protection against low temperatures without compromising the perception of ambient sound.

  This is achieved according to the invention by a safety helmet according to claim 1. Advantageous embodiments of the safety helmet according to the invention are indicated in the dependent claims.

  In the safety helmet of the present invention, the ear protector is arranged on the helmet so as to be adjustable in the vertical direction. Further, the central region of the ear protector is preferably configured to allow sound to pass through the openings in the central region of the insulating material.

  As a result, the ear protector can be adjusted so that the central region through which the sound passes is located at the height of the hearing conduction path of the helmet wearer so as to ensure optimal perception of ambient sound when worn. At the same time, a helmet wearer can ensure that the entire ear is covered as best as possible by adjusting the ear protector up and down, thus ensuring optimal protection against low temperatures.

  For vertical adjustment, for example, a Velcro closure can be provided between the ear protector and the helmet shell. However, in order to ensure secure fixation, each ear protector preferably has at least two insertion pins or insertion holes arranged in a row in the longitudinal direction of the helmet, each side of the helmet being At least 2 arranged in rows at equal intervals in the longitudinal direction of the helmet for inserting at least two insertion pins of each ear protector or for insertion into at least two insertion holes of each ear protector Has two insertion holes or insertion pins. For vertical adjustment, either the helmet or the ear protector, with at least two insertion holes or insertion pins at the same distance in the longitudinal direction of the helmet, but up and down from the first two insertion holes or insertion pins There is provided at least one further row arranged in a staggered manner. Here, “at least two” should be understood to mean “two or more”.

  For example, each ear protector can be provided with three insertion holes shifted in the longitudinal direction of the helmet, i.e. arranged in a row, while the helmet is for example on the outside, for example with three insertion pins each Have three rows arranged one above the other. Further, each ear protector can be provided with three rows of insertion holes arranged one above the other, and the helmet can be provided with one row of insertion pins.

  Preferably, however, each ear protector has, for example, three insertion pins arranged in a longitudinal row of the helmet, while three rows of, for example, three insertion holes each are vertically arranged on the inside of the helmet. Provided shifted in the direction. In this way, the three pins of a particular ear protector can be inserted into the three insertion holes at the desired height inside the helmet.

  For example, the number of insertion holes in each row of the helmet is greater than the number of insertion pins for a particular ear protector (ie, for example, there are two pins in each ear protector and four insertion holes in each row of the helmet). If present, the ear protector can be adjusted not only in the vertical direction but also in the longitudinal direction of the helmet.

  The helmet shell often has an arcuate recess inside the upper part of the ear, particularly when the back side of the helmet extends downward toward the neck.

  Therefore, at least three insertion pins or insertion holes arranged in the longitudinal row of the helmet, and insertion pins or insertion holes arranged so as to be shifted in the vertical direction from these insertion pins or insertion holes are also the recesses. Are preferably arranged in an arc.

  The ear protector is made of a heat insulating material. For this purpose, each ear protector can have, for example, a rigid core made of, for example, a plastic foam provided with a cover made of, for example, leather or cloth.

  The insertion pin of the ear protector is preferably provided on the frame or band, and the heat insulating material is fixed to the frame or band by, for example, sewing or bonding. The strip or frame, together with the insertion pin, is preferably constructed in one piece, preferably as an injection molded plastic part. The ear protectors on both sides of the helmet can be connected to each other, for example by a strap, for example a pad, optionally extending the neck region below the helmet shell.

  In order to allow the central region of the ear protector to pass sound, an opening, preferably sealed by a thin and sound-permeable fabric, is provided in the central region of the insulating material (ie foam core, for example) Is provided.

  The insertion holes arranged in at least two rows positioned one above the other are preferably provided in a mounting seat arranged inside the helmet shell. A mounting seat, which can be constituted by a plate, can be fixed to the helmet shell. For this purpose, at least the inside of the helmet shell can be composed of plastic foam, and the mounting seat can be provided with an anchor that can be embedded into the foam material when foaming. The mounting seat with the anchor can be constituted by an injection-molded plastic part.

  A flexible lining that spreads as a pad that also covers the band of the ear protector can be provided inside the helmet.

  The safety helmet of the present invention is particularly intended for winter sports users such as snowboarders or skiers. However, it can be used in places where optimal hearing is important at low external temperatures, for example as a bicycle helmet or at construction sites.

  In the following, embodiments of the safety helmet of the present invention will be described in more detail by way of example with reference to the accompanying drawings.
