“…In on the other hand, 4 responses (7%) expressed indifference about this aspect and 2 (3%) indicated that they were of reasonable importance. The importance attributed by most respondents is close to what was identified in studies that children's life jackets with ergonomic comfort, similar to a vest that was familiar to both the child and the adult in their personal clothing, looking like a child/infant day-to-day clothing encourages their use for a longer period of time [7,13].…”

Drowning is a dramatic situation, with very serious consequences and with economic impact, since when it does not cause death, causes sequelae that will affect the victim throughout his life. With regard to children, the prevalence of drowning death is higher than deaths caused by tuberculosis or measles. Considering the context of these accidents, it is known that the immersion occurs without shouting or "noises", which makes it even more difficult to detect and rescue. Rescue agility is crucial for the survival of victims, as after being submerged for only 2 minutes, the victim loses consciousness and after 4 minutes brain damage can become permanent and unalterable. Even if they survive from being submerged for some time, the victims may suffer from severe and often irreversible neurological sequelae [1, 2]. From this perspective, developing safety mechanisms for children requires knowledge of the unique needs of these individuals, arising from the cognitive and motor development of this stage of human development [3, 4]. To foster this problem, the work proposes to develop a usual garment that contains an integrated rescue device for children. The main design challenge is the harmonious matching of the rescue device's function with the fashion item, making it unnoticed. The work presented is feasibility study (online survey), which aims to verify the acceptance of parents/guardians regarding the launch of such product concept, which is presently under development, and the requisites that it should comply with.

“…The perception of the majority is adequate, as situations of leisure close to water environments are not restricted to seasons. Playing around swimming pools, lakes, rivers and even on the deck of a boat can be an example of an environmental context where the child needs to be with the buoyancy aid [13].…”

“…Devices for preventing drowning are known by different names in Europe, the USA, and Canada, such as life jackets, buoyancy vests, flotation aids, and personal flotation devices (PFDs). 1 Wearing an appropriate life jacket (or PFD) was found to reduce the rate of drowning mortality; [2][3][4][5] however, their usage rates are not particularly high. 6,7 According to the US Coast Guard's recreational boating statistics for 2010, almost 75% of the victims of all fatal boating accidents drowned, and of those, 88% were reported as not wearing a life jacket.…”

To produce a life jacket that fits users both comfortably and stably, we developed a life jacket pattern based on the three-dimensional (3D) shape of the human body, with foam flotation material of different thicknesses used in different sections to achieve the required buoyancy and facilitate movement. We created a nonstandard life jacket for water sports that can adopt free design for canoeing and kayaking. Engineering design process and 3D technology were used to create the ergonomic 3D life jacket, which comprised an inner pattern, a polyethylene (PE) foam pattern for proper buoyancy in water, and the outer pattern. We developed a layering method for achieving the heterogeneous thickness of the life jacket and its outer pattern considering the ergonomic aspects of the 3D human body curvature and movability. The pattern expansion length was calculated to enlarge the outer pattern of each panel covering the varying thicknesses of life jacket and spacing for torso flexion. The calculation formula for this length was useful in increasing or decreasing the life jacket’s buoyancy, which was affected by the PE-foam thickness. Human-subject wear tests were performed in air and water to evaluate the developed life jacket. The developed life jacket had improved functionality. Significant differences ( P ≤ 0.01) existed between the newly developed and conventional life jackets in air, in terms of the overall comfort, freedom of rowing movement, and fits in the chest and waist areas. Significant differences ( P ≤ 0.05) also existed in water in terms of the overall fit and prevention of separation from the shoulder due to buoyancy.

“…Recently, with a grant from the Transport Canada Marine Safety Branch, his team was asked to evaluate a series of child/infant life jackets [3]. This gave the researchers the opportunity to examine the practice effect of donning life jackets and report their findings in the process of testing the life jackets for a new Standard No.…”

The Influence of Familiarity on Life Jacket Donning Performance: Implications for Participant Selection

Laboratories and test houses keep a "pool" of test subjects that volunteer to be participants in life jacket approval testing, which is believed to be an incorrect procedure. Fifty-six participants donned 8 child/infant life jackets onto 4 infant manikins in random order with time and accuracy of donning recorded. Average donning time for all 8 life jackets decreased significantly after the first donning experience. The findings show that the effect of familiarity occurs immediately after the first test, regardless of life jacket type, thus "contaminating" the subject and making them unsuitable for further tests. These observations are important for life jacket standards where the life jacket must be donned by a naïve participant. Currently, a poorly designed life jacket may receive a pass as a result of the learning effect as shown by participants with previous donning experiences.
