DESCRIPTION:
BRIEF SUMMARY
This invention relates to a combination of a helmet and a respirator.
Nowadays, traffic jams car be a problem, especially in population centers. The air entering roofed automobiles is purified by passing it through fresh air filters whereas people using roofless automobiles, motor cycles, mopeds and bicycles are exposed to airborne impurities. They can, however, resort to using non-integrated, separate respirators. The problems with non-integrated respirators are that they are not comfortable, the impediment to breathing caused by them can be considerable, and the respirator easily becomes wet. Respirators are difficult to get to work both when the wearer is in motion and even when not in motion. Moreover, the helmet's safety construction is impaired because, the respirator is not integrated with the safety helmet. One purpose of the invention is to come up with such a respirator aimed at the aforementioned vehicle users as will not cause essential losses in the properties of safety helmet. When under the influence of the slipstream of air caused by motion and when at standstill (at traffic lights), the respirator worn by the vehicle user must work so that the wearer does not have to breathe in exhaust fumes and dust.
The other purpose of the invention is to come up with a combination of different safety helmets and respirators such as an integrated welder's helmet and/or mask, military helmet, and a construction worker's safety helmet. Respirators integrated with chin guards have not been employed in the said helmet types. In cases where air has been purified prior to being inhaled, it has taken place in a separate purification device from which the purified air has then been led into the respirator. Welders and foundry workers are exposed to a variety of harmful gases. It is, difficult to protect oneself from smoke non-integrated respirators. Masks, on the one hand, and respirators, on the other hand, are generally used as alternatives--not simultaneously. Simultaneous use may lead to a situation in which the respirator cannot be brought firmly enough against the face. Since the respirator and the helmet and/or the mask are separate devices, they are difficult to use and for this reason work safety instructions are neglected.
Currently there are various ways of attaching a respirator to a helmet so that the respirator adapts keenly to the contours of the wearer's face. Another popular solution is to have the inhalation air filtered outside the helmet with hoses being linked to the helmet via which the purified air is then led in to be inhaled. Generally, this air is pumped into the hoses under a certain pressure.
A helmet without a chin protective arch is referred to by the name of half helmet while a helmet with a chin arch is called a full helmet. When a half helmet is provided with a respirator, the end result is not good from the standpoint of safety because it does not provide simultaneous protection for both the chin and the face. Since a respirator mounted in a half helmet has to be attached firmly against the face of the wearer in order to minimize leakages, it may be uncomfortable to the wearer. Considering the lengthy periods that a respirator often needs to be worn, it may cause sensations of sweatiness and uneasiness. Currently, a person wishing to breathe filtered air is forced to select a half helmet instead of a full helmet at the cost of reduced safety.
The solution in accordance with the invention brings about a marked improvement with respect to the aforementioned shortcomings. In the embodiment of this, the solution in accordance with the invention is characterised by what is presented in claims 1 and 9, respectively.
A significant advantage of the invention may he seen in the aspect that the respirator as a whole has been made an integral part of the helmet. The functioning of the respirator can be regulated according to whether the wear is in motion or at standstill. The said respirator can be worn even for lengthy periods of time without discomfort as the sealing part of the face el
