FIELD OF THE INVENTION
[0001] The present inventions relates to the field of human activities involving staying in water, in particular, it can be used in order to teach swimming and escape drawing, in the course of physical training and auto-training, and in sports, medicine, etc.BACKGROUND
[0002] There are various modes of swimming (see, e.g., description of RU Patent No. 2,003,370 C1), which employ auxiliary means in order to increase buoyancy of the human body. Such means, while offering convenient aid in learning of unskilled swimmers, do not help to overcome the main difficulty, that is, fear to sink into water (fear of depth). These auxiliary means are rather misleading, making an unskilled swimmer dependent on the availability of such technical aid. In order to make possible the use of the auxiliary means of increasing buoyancy, these devices, despite their relatively large dimensions, must be always at hand. A special class of means that is worth of mentioning includes lifebelt...
