Description

The invention relates to a protective helmet as it is in the preamble of the main claim is described.

Protective helmets (e.g. for motorcyclists) have existed since the beginning of the eighties, which have a hinged chin part; such helmets are shown below Called flip-up helmets. This form of shelter enables e.g. Glasses wearers put on the safety helmet comfortably without taking off their glasses, or e.g. Motorcycle police officers without taking off their hard hat To conduct a dialogue with other road users with the helmet chin part open. The Accumulation of several steps when putting on the helmet (putting on, Close the chin strap, fold down the chin section) for short distances (e.g. in the City traffic) often to ensure that the chin strap is not closed. Of many people wear protective helmets at high outside temperatures and low driving speed (e.g. inner city) with the chin part open drive. After all, flip-up helmets are on the market, which are characterized by the dismantling of the chin part from the "full face helmet" to the "open face helmet".

EP 0 258 496 B1 shows a protective helmet with a fold-up chin part, in which a bracket, which takes over the function of a chin strap, when folded down of the chin part automatically creates. The bracket is placed over cams and swivel links controlled relatively expensive.

From DE-U1 78 28 327 a two-part chin strap can be removed, the both parts by a main closure and an additional snap fastener can be connected.

The object of the invention is to design a generic hard hat so that it is simply constructed and conveniently securely attached to the head of the helmet wearer can be fixed even when the chin section is folded up or removed.

The object is achieved with the characterizing features of Main claim solved. Further advantageous designs result from the Dependent claims.

According to the invention, the chin strap automatically lies down when the chin part is closed on. Preferably the helmet wearer with the flip up or off To drive the chin part, he can also attach a chin strap to the helmet shell, which he then closes manually in a known manner. So that's safe Guaranteed wearing the protective helmet in these situations. Accordingly, it causes more generally, the invention involves a forced use of the chin strap closed chin section, which increases safety in the event of a possible Accident leads. It is characterized by a more comfortable use by a few simple steps when putting on and closing the protective helmet eliminated. Nevertheless, all functional features of a flip-up helmet are maintained. Furthermore, the protective helmet wearer can e.g. at high outside temperatures remove the chin part; through the one to be attached to the helmet shell Second chin strap is also the safe wearing of the Protective helmet guaranteed.

In an expedient embodiment, the chin strap is attached to the chin part in such a way that when the chin part is folded down, it is in a concentric circular path moved around the chin part pivot point and in the closed chin part position leads to firm, secure contact with the neck of the helmet wearer.

It is also expedient to design the length of the chin strap so that it can be changed that the respective user can set them individually for his needs. A Comfort is increased by padding the chin straps.

In a particularly expedient embodiment, the one provided on the chin part Strap designed and attached so that it can be removed and attached to the helmet shell can be attached. In this case, there is no need to carry a second one Chinstrap.

Further advantageous refinements of the invention result from the following description of an exemplary embodiment, which refers to the accompanying drawing. It is shown in

4 shows a side view of the section labeled "X" of a chin strap part according to FIG. 4.

A flip-up helmet 1 according to FIG. 1 essentially consists of two main components: one Helmet shell 2 and a chin part 3 which is rotatably articulated on the helmet shell 2. For this purpose, a swivel joint is provided on each side of the helmet; the fulcrum of one Joint is designated by 4 in FIG. 2. With this arrangement, the chin part 3 fold up to remove the helmet, as shown in Fig. 2 with the dash-dotted line 5 is indicated.

Fig. 3 shows a chin strap, generally designated 6, on both sides the helmet shell near the fulcrum 4 fixed in such a way that he is firmly connected to the chin part. It moves up when the chin part 3 is opened a concentric circular path around pivot point 4. It moves from Neck of the safety helmet wearer, not shown, away at the chin tip and later on past eye level and thereby allows the helmet to be removed. The Movement path is again designated 7 in FIG. 2.

The chin strap 6 is on the right and left on the inside of the chin part 3 by means of slotted mounting plates 8 fixed with several screws 9 on the chin part 3 are attached. One end 10 of the chin strap 6 is through a slot 11 (Fig. 2) the left in Fig. 3 mounting plate 8, folded and again with sewn on the chin strap. On the other hand, the corresponding end becomes 12 the chin strap 6 through a comparable slot of the one there Fastening plate 8 out and with the section of the chin strap between the mounting plates frictionally connected via a buckle 13. This In addition to fixing the chin strap, the buckle also ensures its Length adjustability. This adjustability is due to the adjustment of the helmet to the different head and neck shapes of the protective helmet wearer. Finally, the chin strap 6 between the mounting plates 8 by means of a Comfort padding 14 covered.

Fig. 4 shows a second chin strap, which are attached to the helmet shell can. It is provided when the chin part is either folded up or is removed. The chin strap 15 is designed in several parts and sections 16, 17 can be attached to the helmet shell on the right and left using screws or rivets. The helmet shell and the fixing of the chin strap in the helmet shell are shown in Fig. 4 not shown, but the sections 16, 17 show tabs 18, 19 with Through holes for the fastening screws or rivets.

At the other end of the sections 16, 17 there are connecting elements 20, 21, to which two middle parts 22, 23 of the chin strap 15 can be attached.

The connecting elements 20, 21 are designed as eyelets and can be in Hook in buttons 24, 25 of the middle parts 22, 23. 5 shows as detail "X" of FIG. 4 the undercut shape of the button 25. The connections of the middle parts 22, 23 with the components carrying the buttons 24a, 24b and the chin strap sections 16, 17 with their connecting elements 20, 21 are carried out by looping, turning and sewing the ends of the middle parts 22, 23 and corresponding to the ends of the Chin strap sections 16, 17.

The middle part 22 has a lock 25, which has a push or slide button 26 can be actuated. Furthermore, the middle part 22 has a comfort padding 27 padded to improve the comfort of the chin strap. The Counterpart to the lock 25, namely a lock tongue 28 is with the second Middle part 23 sewn. When closing the chin strap in a known manner Lock and tongue inserted into each other and in a corresponding manner Push or push button pressed to release the parts again.

The end of the middle part 23 facing away from the lock tongue 28 is replaced by the Button 24b-carrying component looped through, but not sewn. Rather, it becomes one Buckle 29 guided and held there frictionally. In this way it is entire chin strap 15 adjustable in length and thus on head or neck shape the helmet wearer adaptable. The two middle parts 22, 23 can - how already indicated above - if necessary to the helmet shell fixed Button the chin strap parts 16, 17 and then form a comparable function the previously used standard chin strap. If the middle parts 22, 23 - the in the described embodiment, the actual additional chin strap form - not used, the hard hat wearer can use them as loose accessories carry. The helmet-shell-fixed chin strap parts 16, 17 remain on it Position, but then no longer have a function. If necessary, you can in appropriate pockets are inserted inside the helmet so that they are no longer visible from the outside.
