Definitions

  • the present invention relates to a wearable assembly, such as an article of clothing or a life-jacket, for providing a rescue function, such as buoyancy.
  • the present invention also relates to a shirt embodied as such a wearable assembly.
  • the present invention also relates to a gas generator for generating gas for use in a wearable assembly according to the present invention.
  • the present invention further relates to a method for providing a rescue function to a person.
  • the present invention further relates to a method for initiating a gas generator for use for a personal rescue function.
  • Drowning is a major cause of death and a cause of disability, particularly in children but also in adults. This of course happens when the attention of a person is distracted and the person has no defence when taken by surprise by water. Small children in particular are unaware of the danger and drown without an alarm being raised. A water depth of 5 cm can already have fatal consequences here.
  • a major problem here is that a person is unconscious within two minutes and irreparable damage is caused within four to six minutes.
  • a life-jacket is of course known per se for preventing death by drowning.
  • a life-jacket is however mainly aimed at use on board vessels where there is a specific risk of falling overboard.
  • a life-jacket is hereby intended specifically for a situation where a person falls overboard and has to survive in a body of water for a possibly longer period of time.
  • Drowning as referred to above mainly occurs when the danger is less clearly recognized, as in the case of passengers, in the case bodies of water are located in the neighbourhood of the person or when the person is for instance on holiday and is exposed to relatively unknown risks in respect of the presence of water. In such situations wearing a life-jacket is perceived as very unusual or probably not even identified as an option. The reason for this is that a life-jacket has undesirable characteristics compared to regular clothing. A life-jacket is generally unsuitable for heat insulation. In view of the purpose of ensuring survival when falling overboard from a vessel, a life-jacket is also provided with features greatly influencing normal wearer comfort.
  • the present invention provides a wearable assembly, such as an article of clothing or a life-jacket, for providing a rescue function, such as buoyancy, the wearable assembly comprising:
  • An advantage of such an assembly is that, by applying this gas generator comprising a precursor for generating gas, an assembly can be provided wherein the gas generator can be given a relatively very compact form compared to buoyancy-generating means of for instance a life vest.
  • Such a cool gas generator is able to provide a very high gas volume relative to the size, weight and/or volume of the gas generator.
  • a further advantage of such a gas generator is that it can be stored for a long period, up to 10 years or longer, after which period it still functions and can be activated in the usual manner. This is advantageous since it enhances convenience of use, compared for instance to systems with CO2 cartridges based on expansion. Such old-fashioned systems require a one, two or three yearly check or replacement of working parts.
  • the operational principle of generating gas from a precursor is in principle known for the purpose of providing a propelling action, such as for rocket engines or in the aerospace industry.
  • the application of a gas generator in an assembly according to the present invention provides the particular advantage that a high wearer comfort can be achieved in that the gas generator makes only a small addition to the size or the weight of the assembly.
  • the assembly can hereby be embodied in a manner which resembles a regular article of clothing, such as a shirt or vest. While such a shirt or vest is made somewhat heavier by/for the purpose of the gas generator and the fluid holder, it can nevertheless be worn almost as a regular shirt, and provides a much greater wearer comfort than a per se known life-jacket.
  • the support structure in the wearable assembly has a wearer comfort similar to the wearer comfort of a vest or shirt, such as a T-shirt, blouse, sports shirt and the like.
  • the gas generator is of a cool gas generator type.
  • a gas generator is for instance known from the international patent application WO 03/009899. In this patent application the generation of gas is aimed at providing oxygen to for instance divers or for the purpose of driving rocket engines.
  • substantially a low reactive or inert gas is generated under operating conditions, such as nitrogen or carbon dioxide, or wherein moderately reactive gases are generated, such as oxygen or hydrogen. It is even possible to generate a gas such as hydrogen, depending on the choice of precursor, although the choice is mainly determined by a maximum gas yield per weight of the gas generator and the safety of the use in providing the rescue function.
  • precursors used comprise alkali metal chlorates and alkali metal perchlorates, in particular lithium perchlorate (LiClO4), lithium chlorate (LiClO3), sodium perchlorate (NaClO4), sodium chlorate (NaClO3), potassium perchlorate (KClO4) or potassium chlorate (KClO3), peroxides, in particular sodium peroxide (Na2O2) and potassium peroxide (K2O2), superoxides, in particular potassium superoxide (KO2) and sodium superoxide (NaO2), although many further examples are possible within the understanding of the skilled person.
  • the choice of precursor depends of course on the choice of the final gas.
  • the fluid holder in the wearable assembly more preferably comprises a bladder or balloon preferably arranged for holding above water a head of a wearer who has fallen into water.
  • a plurality of forms of the fluid holder can hereby be obtained in both the empty and full state. This is important on the one hand for holding at least the mouth and the nose of the user as well as possible above the water surface.
  • a bladder can be manufactured from a plurality of materials, so that choices of material can be made which contribute toward greater wearer comfort. This also makes it possible to provide an article of clothing having a normal wearer comfort which can in principle be worn in the same way as an article of clothing not having a rescue function.
  • the fluid holder comprises a textile which, during or after wetting with a liquid such as water, has gas-tight properties.
  • a textile can for instance have a breathing action during normal use.
  • the fluid holder can be embodied as part of the article of clothing. When the article of clothing becomes wet, the fluid holder will become gas-tight, whereby an inflatable fluid holder is provided in effective manner which can provide the rescue function.
  • the fluid holder more preferably comprises at least one material layer which forms a material layer of the assembly, such as an article of clothing.
  • a material layer which forms a material layer of the assembly, such as an article of clothing.
  • Two layers are hereby in principle sufficient to form the fluid holder and the article of clothing. This further enhances the wearer comfort compared to embodiments wherein a material layer is necessary for the article of clothing and two layers for the fluid holder.
  • the gas generator is suitable here for producing CO2 gas while applying substances comprising a bicarbonate, such as sodium bicarbonate, potassium bicarbonate, calcium bicarbonate or ammonium bicarbonate, for instance while applying an acid.
  • a bicarbonate such as sodium bicarbonate, potassium bicarbonate, calcium bicarbonate or ammonium bicarbonate
  • the fluid holder preferably comprises a nanofibre, such as for instance of the nylon 6.6 type. At least one layer of the fluid holder more preferably comprises a breathing material. This increases wearer comfort. This increases wearer comfort. A fully sealing membrane for forming of the fluid holder can cause perspiration to accumulate between the skin and the fluid holder. The breathing action can prevent this because it can (help to) discharge the moisture.
  • the assembly more preferably comprises an actuator for the gas generator, the actuator preferably being a mechanical actuator, more preferably comprising an energy source for mechanical energy, such as a spring, preferably dimensioned in the order of magnitude of the gas generator. It hereby becomes possible to have actuation take place automatically in a manner suitable for specific use. Alternatively, a manual actuation is possible.
  • the wearable assembly is preferably suitable for providing a rescue function for children with a clothing size fitting children of age 0-1, 1-8, more preferably 1-6, more preferably 1-5, more preferably 1-4, more preferably 1-2, more preferably 2-3, more preferably 3-4, more preferably with fitting length sizes, more preferably with rescue function suitable for the weight.
  • the wearable assembly is provided with properties such as protection against cold and heat, preferably breathing, preferably washable in normal domestic manner.
  • properties such as protection against cold and heat, preferably breathing, preferably washable in normal domestic manner.
  • Substantially the same advantages are provided here as in the case of a normal shirt. Maintenance is easy since a wearable assembly can be easily washed, wherein, depending on the embodiment, no parts need be removed, and for instance in an embodiment where the actuation follows automatically upon contact with water, the gas generator and/or an actuation member need be only temporarily removed.
  • the bladder is more preferably arranged and formed such that particularly the front side of the head is held above water when a person falls into water, preferably by providing buoyancy at the position of the neck and throat below the ears. This insight makes it possible to optimize the wearer comfort in respect of the minimal size of the bladder.
  • the bladder is preferably arranged here particularly close to the shoulders and the throat of the person.
  • the gas generator comprises gas-forming substances which can preferably be actuated by means of mechanical energy, can more preferably be actuated by means of contact with water, wherein the gas generator can preferably be arranged under one or both of the armpits.
  • An automatic actuation of the process of forming a gas can hereby be started.
  • the assembly more preferably comprises a reaction accelerator such as an acid.
  • a reaction accelerator such as an acid.
  • the reaction speed of the precursor may in itself be relatively low in relation to the required time.
  • a reaction accelerator can provide a life-saving advantage here.
  • the support structure comprises a harness, preferably an adjustable harness which can be modified to multiple body sizes. Particularly in the case of small children a passage of time of several months can already result in such growth that another size is required.
  • An adjustable harness can enable the assembly to be worn for a longer period of time.
  • the support structure of the assembly is suitable for wearing over clothing, such as a jacket, raincoat, sailing jacket or the like.
  • the function of the wearable assembly over another article of clothing can for instance hereby be provided without a modified article of clothing being required. It is also possible for the assembly to be worn under another article of clothing. Care is preferably taken here that the other article of clothing has sufficient internal space to enable a possible increase in volume.
  • a further aspect according to the present invention relates to a shirt comprising a wearable assembly according to the present invention.
  • a further aspect according to the present invention relates to a gas generator for generating a gas substantially at a temperature which does not damage the human body or the human skin, preferably the corresponding ambient temperature, wherein the gas generator comprises:

  • This is a sports shirt 11 which can be worn as a regular sports shirt.
  • a bladder 18 Arranged in the sports shirt is a bladder 18 , which bladder is present in a rest state in sports shirt 11 . Only in the case of an emergency situation does the bladder have to be transformed from the rest state, in which it can be worn on the body, to an active state in which buoyancy is provided.
  • the active state entails the bladder being filled with a gas, whereby the sports shirt acquires buoyancy for the purpose of keeping a person, such as a child, afloat. It is the primary intention here that the person, such as the child, is saved from drowning.
  • Bladder 18 can take many forms in order to achieve this purpose, examples of which are described with reference to the figures in this description.

  • the operation of the cool gas generator is elucidated in greater detail below.
  • An advantage of the embodiment of the bladder is in this case that while it is worn a high degree of ventilation of the underlying body is achieved. A smaller surface of the bladder in the rest state is effectively advantageous in achieving a desirable measure of ventilation.
  • FIG. 2 shows a further variant of a shirt, in this case a T-shirt, according to the present invention.
  • the T-shirt is provided with a bladder 28 having two floating bodies 28 B arranged at the position of the shoulder and upper arms.
  • a relatively small neck part 28 B of the bladder is also provided in order to impart buoyancy in the area of the neck.
  • a chest element 28 C is further provided in order to impart a relatively great buoyancy in the chest area. This prevents the person entering the water body in tilted forward position. Using this embodiment the person will therefore tilt to the rear and the breathing orifices, comprising the nose and mouth, will protrude above the water body. This situation is shown schematically in FIG. 2B .
  • a neck opening 35 is provided.
