Abstract

Helmet comprises a shell (1) and an anti-theft device (3) consisting of an engagement part forming a closed metal loop (4) for producing a connection to a vehicle which is anchored on the inner side of the shell so that it can be adjusted between a lower position in which it is located within the shell and a position of use in which it protrudes out of the shell. The anti-theft device has an anchoring part which is fixed on the inner side so that it can be displaced or rotated on the shell and a continuous metal connection is created between the loop and the anchoring part. Preferred Features: The connection between the anchoring part and the loop is produced by an elongated connecting part.

Description

Technical field

The invention relates to a helmet with a Anti-theft device, such as that used by drivers of Motorcycles, but also bicycles and other vehicles is worn to protect against head injuries.

State of the art

Most motorcycles have so-called helmet locks attached, which a closable bracket or a Include hooks, the ends of which are separated by a removable part, e.g. a section of the bench that is closed by a lock can be secured, are covered. In both cases there is a closed loop on the motorcycle, on which even a helmet without specific anti-theft protection Attaching the chin strap can be secured. This kind the backup is very unreliable, however, because one Opening of the chin strap at most precludes the circumstance, that access to its closure is somewhat difficult. In addition, this can usually consist of a fabric Chin strap lightly with scissors or a knife be severed.

For this reason, many suggestions have already been made to provide the helmet with an anti-theft device, which is a reliable attachment to the helmet lock allowed.

A generic helmet is known from US-A-4 101 983. There is a ring that can be hung in a helmet lock can be pulled through two loops which by means of a rivet on the inside of the shell are attached. The inner loop is proportionate short but elastic and keeps the ring in a sunken Position in which he is little out of a slot in the Shell of the helmet protrudes. Stretching the inner The ring can be looped through the longer one, however inelastic outer loop defined position of use in which it is almost completely outside the Bowl lies. Theft protection can be used with this solution be rendered ineffective by using both loops a pointed instrument inserted through the slot, e.g. of a knife.

From US-A-5 117 662 a helmet is known which rear one attached to the inside of the bowl at the bottom Padlock-like theft protection carries with you Bracket, which can be fixed in two recessed positions and can also be opened completely. This construction is relatively complicated, complex and heavy and takes up a lot of space. If, as is usually the case, a helmet lock is present, the high effort is not associated with advantages, but only complicates the Use of the anti-theft device.

In US-A-4,676,080 there is an anti-theft device for one Bicycle helmet described, in which one of one Wire rope loop formed by a round opening in the shell is pulled outwards, while the ends of the Wire rope on the inside of the shell through a sleeve are connected. So that the loop does not go through the opening can be pulled, it is from within the shell arranged annular stop surrounded. she is but not firmly attached to the helmet.

FR-A-2 351 850 shows a helmet with which on the side parallel to the chin strap made of solid, at least partially metallic material braided bands are provided which integrates with side sections of the chin strap could be. They have holes at their lower ends, through which e.g. a chain can be pulled. This Solution is pretty much as it requires another part inconvenient for the user and apparently not for the user Intended for use with a helmet lock, but rather for the helmet is fixed to the handlebar or frame.

Presentation of the invention

The invention is based on the object Specify generic helmet, its theft protection ensures a high level of security. This task is characterized by the features in the characterizing part of claim 1 solved. The helmet according to the invention has an extreme reliable anti-theft device, which at the same time is easy to use and at the same time be small and light can so that it does not interfere with the wearer at one Accident not at risk. The anti-theft device is also inexpensive and does not require any adjustment to the structure of the Helms. Its characteristics regarding other aspects like Strength or aerodynamics are therefore not affected.

Ways of Carrying Out the Invention

According to a first embodiment (FIGS. 1-3), the helmet according to the invention an outer shell 1 Hard material, preferably hard plastic, to which on the Inside a padding 2 with a layer of Foam, e.g. Styrofoam, which inside of a Fabric layer is covered, connects. A Theft protection 3 comprises as an engagement part for the Engagement with the helmet lock is a braided of steel wire fixed closed loop 4 and one with the same one-piece flat, also braided from steel wire Band 5, which forms a connecting part that the loop 4 connects with an anchoring part at the upper end. The the latter comprises a cylindrical cross bolt 6 around which the top section of the tape 5 is guided and through a Seam is closed in a loop. The cross bolt 6 protrudes a bit on both sides of volume 5.

On the inside of the shell 1 is in a recess Upholstery 2 an approximately transverse to the edge and scarce attached above the same longitudinal guide 7 with a groove 8 in which the anchoring part is displaceable is led. A stop 9 is provided at the lower end, which narrows the cross section of the groove 8 so that the Band 5 can happen, but not through the cross bolt 6 thickened anchoring part.

There are various modifications to those described Theft protection possible. It is crucial that the connection between the closed loop and the anchoring part consistently of metal, preferably Steel is made so that it is very heavy and not medium usual tools such as knives, scissors or pliers is severable. It can be described as out Steel wire braided tape or braided or knotted rope, but is also a Training as a solid, preferably flexible steel band or as a chain, for example connected to a stiffening Strips of fabric, plastic or leather, conceivable.

Thanks to the elongated connecting part, the loop is 4 in the use position shown in Fig. 2, 3 relatively far from the lower edge of the shell 1 removed so that the helmet is conveniently attached to the helmet lock and can be removed from the same. It is advantageous if the connecting part has a certain Having flexibility in at least one direction, such that it adapts to the curvature of the shell 1, but at the same time also sufficient rigidity that it enables the theft protection from the use position in to push the sunken position upwards, in the only part of the loop 4 protrudes over the edge of the shell 1. With constant curvature of the shell in the area of the guide the connecting part can also be rigid.

It is also an advantage if the anti-theft device is in the submerged position is held. This can be a Spring element can be provided with the anti-theft device applied an upward force so that it is biased against the sunken position or the one that Anti-theft device holding in the recessed position elastic snap lock forms. Alternatively, you can between the groove and the anchoring part also easier Friction prevail, so that theft protection of your Shift always opposes a low resistance.

The loop 4 forming the engagement part can also (FIG. 4) are formed by a closed ring, which on lower end of the band 5 is attached.

According to a second embodiment of the invention Helmet (Fig. 5-7) the anti-theft device is slightly different executed and anchored differently, while the helmet otherwise is the same as in the first Embodiment.

A button 10 is attached to the shell 1 by means of a rivet Attached on the inside. The anti-theft device 3 consists of essentially a closed one made of wire Rope 11, preferably a steel rope, which at one end again one fixed by a wire wrap Has loop 4 as an engaging part and on opposite end a the tapered base of the button 10 correspondingly surrounding further loop 12. Das Connection part between them is made by parallel Sections 13 of the rope 11 are formed. Engagement part, Anchoring part and connecting part are therefore in the essentially in one piece.

The loop 12 can be so tight around the base of the button 10 be guided that theft protection by friction is held in the sunken position. Alternatively, you can they snap-locked by a spring element or by the Upholstery clamped. Again, of course Variations about the training of the Engagement part or the connecting part - about as in Described in connection with the first embodiment - possible. The anti-theft device can also be anchored be realized in another way. For example, the button itself rotatably mounted on the shell and the Anti-theft device must be firmly connected to it.
