Description

Utility model registration Protective helmet with swiveling, curved visor

It is known to pivot transparent animals on protective helmets; mostly they are located on a bracket which is mounted at the front points on the forehead and can be pivoted against a lock or a second bracket as a stop. The known constructions have the disadvantage that the visors either face the face of the helmet wearer schütze.n only in certain areas or fogged by breathing and wind in motorized germ carriers and thereby <? obstruct \ e view or when they were swung over her eyes, hindering for motorized helmet makers in the wind, or cause unpleasant ^ felt expectant flow conditions. The usual constructions are also inadequate or impractical against blinding incidence of light. The visors can usually only be swiveled in stages by means of spring-loaded latching means, instead of with the possibility of continuous fine adjustment.

The innovation described below overcomes all of these disadvantages and opens up additional advantages due to its peculiarity:

A face shield made of transparent material is according to the invention arched in such a way and arranged on the side of a protective helmet so that it can be pivoted so that when it is pivoted up, the face area is up via the eyes, without the air flow conditions being affected by the airstream W3wisely change, what will be done by a the helmet body adapted curvature is effected. In down position the visor also covers the wearer's chin and can add a Have stiffening. The upper and lower edges of the visor run in such a way and their distance from the face and helmet is determined in such a way that that according to the well-known laws of flow technology, fogging is caused by a suction effect of the airflow and fresh air supply the disc is prevented. The visor can be steplessly adjusted over the entire length by means of a rotary knob or a handwheel on one side. predetermined swivel range arranged rotatably. The threatening button on the opposite side leaves a second button between the one mentioned Visor and smaller anti-glare visor attached to the face also swivel actuate. The pivoting is just so easy and so difficult that the known friction means Visors even when the vehicle is jolted or when the head is moved violently in each position that has been set, they just remain fixed, while they are due to higher manual forces on the handwheel and their position can be changed using the handwheel.

In a special embodiment, partial areas are also possible of the visor over the eyes and there also transparent, to relocate and / or move parts that are designed for special optical effects.

An exemplary embodiment is described in the following three figures:

Bares anti-glare visor (3) between the face and the curved visor (1) is also rotatably arranged. At the lower limit (8) there is a stiffener (9) in the chin area to increase the dimensional stability and the protection value. One Part of the face protection (1) is cut out over the eyes and releasably connected to an exchangeable, likewise transparent component (10).

Figure 2

shows in a front view again the face protection (1) on both sides of a helmet body (2) with pivot point at (4) _f which is chosen so that when the visor is in the lower position the whole face is covered, and such a large air inlet and outlet gap between The face and visor are created so that the visor does not rest in position when the vehicle is standing and taking into account the suction effect of the airflow, even when driving. Handwheels (5) are arranged on both sides, with one handwheel swiveling the face protection (1) and, as the opposite, the anti-glare protection (3). Figure 3 shows how this is done in section.

Figure 3

The handwheel (5) acts on a toothed segment (7) via a toothed wheel (6) so that the face protection (1) and / or (3) can be continuously adjusted in any desired position and even in the event of vibrations Driving or sacred head movements are self-sustaining.

Claims (6)

S c h u t ζ a η s ρ r ü c h 1. c. +, «Helmet, characterized in that a in the form ⁷ elmschale matched face protection is attached to both sides ^r ".." almkörpers so that he a) when swiveling up, the facial area releases up to over the eyes, without thereby affecting the air flow "conditions in the wind can be changed significantly, which is caused by the curvature adapted to the radiator. b) covers the entire face when pivoting down. 2. Protective helmet according to claim 1, characterized in that between the helmet shell and said face protection also pivotably a glare shield is interposed, and that face shield and anti-glare shield are independent let swing from each other. 3. Protective helmet according to claim 1 and 2, characterized in that there is a handwheel at the lateral pivot points, which acts on a toothed segment via a gear so that face protection and / or anti-glare shield are continuously variable in each desired position can be adjusted and retained. 4. Protective helmet according to claims 1-3, characterized in that the distance between the helmet shell and face protection is dimensioned is that in the airstream it exerts a suction effect, which protects the inside from fogging. 5. Protective helmets according to claims 1-4, characterized in that the lower limit of the face protection with a stiffener is designed, which provides special protection for the chin area. 6. Protective helmet according to claims 1-5, characterized in that a partial area of the face shield is recessed over the eyes and is detachably connected to an exchangeable, also transparent part.
