Description of the Invention: [Technical Field] The present invention relates to a protective head cover which is preferably, but not limited to, for the purpose of riding a bicycle, riding a motorcycle or driving a car, and for Need to protect the athletic activities of the helmet. [Prior Art] The protective helmet is mainly used to protect the driver and passengers of the vehicle. The coughing vehicle is a two-wheeled vehicle, such as a motorcycle or a bicycle. °〆 The protective head cover is also used in activities where the head of the participant is subjected to intense/risk movements. For example, such a headstock is used in the field of car racing and in certain group sports, such as hockey or football. Distortion More shackles, protective helmets are widely used in motorcyclists = and are extremely sensible general common knowledge, because of the legal requirements when traveling with such means of transport. Therefore, in order for the head plate to perform its protective function, it is necessary to properly fix the head to the user's head by passing the bar. To the known head of the -f, the chin strap has a first end that securely secures the first portion of the cover. The second free end of the strap is in turn used to removably secure such a second end to the second portion of the cap. In addition, a mechanism for manually adjusting the length is attached to the strap. ^ It can be observed that the length adjustment of the strap can advantageously only be 4 201127306 when the user can prevent the relative movement of the adjustment operation from being used by at least the first person of the surgical scheme to make the head of the strap. Since it is to be avoided, one of the times when the helmet is fitted to the head, it is impossible to know in advance how long the belt needs to be allowed to be securely fixed to the head by the helmet, and at the same time it is uncomfortably pressed on the throat. However, in this case = the user can not see the strap and used to adjust the length of this 'this adjustment is particularly clumsy. With these disadvantages, it has been suggested that the length adjustment of the different technical straps of the protective helmet occurs through the reel having a reel attached to the strap, the strap being elasticized by a spring such as a coil spring. The ground is tightened so that the belt can be spontaneously rolled up by the reel. Such technical solutions are described, for example, in the patents IT 丨 324843 and DE 3 302004. Although such technical solutions of the prior art are able to more easily adjust the length of the entire tape, they have additional disadvantages. Indeed, in the patent documents IT 1324843 and DE 3; 3〇2〇04, the tape reel is fixed to the inside of the helmet cap on the inside, in a space formed in the pad of the helmet. Such a technical solution is awkward for the user to actuate the tape reel. In addition, such a technical solution is also dangerous because it removes a part of the protective pad of the helmet and introduces a hard component into the vicinity of the user's head. In addition to this, the manufacture of helmets with such a reel requires very complicated fixing and assembly operations. SUMMARY OF THE INVENTION 5 201127306 The object of the present invention is therefore to provide a protective helmet, which is preferably, but not limited to, used for riding a foot. A bicycle, a motorcycle or a driving car, and for use in need Protecting the helmet from the 遝 冰 〜 ~ π linkage activity, the protection helmet allows the disadvantages of the known solutions mentioned above, i, the point can be at least partially overcome, and the user wearing the helmet for the reel Usability.
