Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a safety device including a shock absorbing core such as a life jacket, a seat belt pad, a disaster prevention hood, etc. used as a buffer for shock loads for traffic safety measures and earthquake countermeasures.

[0002]

[Prior art]

 Conventionally known life jackets for infants and adults used for cushioning impact loads for traffic safety measures and earthquake countermeasures are made of urethane cores or quilted materials. And so on.

[0003] When a wearer encounters a collision or the like, these life jackets restrain the wearer with a seat belt hung over the life jacket to prevent the wearer from coming off the seat, thereby securing safety. Is to ensure.

However, in this case, a particularly strong impact load (for example, when a 10 kg infant is subjected to an impact acceleration of 60 G, a force of 600 kgf is applied to a localized portion of the body where the seat belt is hit via the life jacket). In addition, there have been relatively many accidents in which the area turns red or dark, and in which the internal organs and skeleton are damaged.

[0005] Incidentally, it can be said that urethane materials and quilting have almost no effect in absorbing the above-mentioned shock load of 600 kgf which is not common sense.

[0006] Therefore, it is extremely important to eliminate or minimize the above-mentioned accidents.

Heretofore, various measures have been applied to this kind of life jacket and the like in order to satisfy the above-mentioned important points, but they have not been sufficient.

[0008] Of course, there have been many demands for safety equipment with a shock absorbing core, such as a life jacket, a seat belt pad, a disaster prevention hood, etc., which are even more excellent.

[0009]

[Problems to be solved by the invention]

 The present invention has been made in view of the above-mentioned situation, and aims to provide a new safety device with a shock absorbing core, such as a life jacket, a seat belt pad, a disaster prevention hood, etc., which meets demands.

[0010]

[Means for Solving the Problems]

 In order to achieve the above object, the safety device with a shock absorbing center such as a life jacket, seat belt pad, disaster prevention hood, etc. according to the present invention is mainly composed of a shock absorbing core made of a material that can effectively absorb the impact acceleration. A shock absorbing core in which a buffer core sub-member made of a material having a hardness higher than that of the buffer core is laminated is inserted into the receiving side surface.

[0011]

【Example】

 The first embodiment shown in FIGS. 1 and 2 is a life jacket 7 for infants, which has an appropriate elasticity that is neither too hard nor too soft, and has a property of uniformly dispersing and supporting external forces such as impact acceleration. The buffer core main body 1 is made of a conductive sponge material, and the buffer core sub-members 2 and 3 made of a sponge material having a hardness higher than that of the buffer core main body 1 are laminated on the upper and lower shock receiving side surfaces of the buffer core main body 1. The shock-absorbing core 4 is inserted into the body portions 5 and 6 with which the seat belt comes into contact.

A second embodiment shown in FIGS. 3 and 4 is a disaster prevention hood 10 which has a moderate elasticity that is neither too hard nor too soft and has a characteristic of uniformly distributing and supporting external forces such as impact acceleration. The buffer core main body 1 is composed of a dispersible sponge material, and the upper and lower shock receiving side surfaces of the buffer core main body 1 are each provided with a sponge material buffer core sub-body 2, 3 having a hardness higher than that of the buffer core main body 1. The shock absorbing core 4 is laminated, and the shock absorbing core 4 is placed in the left and right side walls 8 and 9.

The pressure dispersing material used in the above embodiment is a viscoelastic foam material, which is provided as a trade name: Tempur.

This viscous elastic foam material has a function of uniformly dispersing the received pressure, a function of supporting an object in a comfortable state having a moderate elasticity and viscosity which are not too hard or too soft, and having a burden on one point. It has the function of not concentrating, has the property of good ventilation, and the property of not retaining moisture.

[Action]

 The shock-absorbing safety device with a shock absorbing core, such as a life jacket, seat belt pad, disaster prevention hood, etc., according to the present invention, has a shock-absorbing material mainly made of a material that can absorb the impact acceleration as described above. Since the shock absorbing core, which is formed by stacking a buffer core sub-body made of hard material, is inserted, when another object collides with the outer surface of the buffer core sub-body, the buffer core sub-body is subjected to the impact acceleration. After receiving the external force, the buffer core mainly receives it in a dispersed manner.Only the local part of the buffer core does not deform significantly, and the entire thickness corresponds to the external force such as impact acceleration. The deformation, that is, the deformation, that is, the collapse is extremely small in thickness.

The present inventor conducted a comparative test for the case where no cushioning material was used, for the case of the conventional example using a urethane sheet, and for the case of the present invention using the shock absorbing core. The result was able to be obtained. When no cushioning material was used: Maximum impact acceleration was observed at 52G. When a urethane sheet was used ... The maximum impact acceleration was reduced to 45G. When the shock absorbing core is used: The maximum shock acceleration has been reduced to 30G.

[0017]

[Effect of the invention]

 As described above, the safety device with a shock absorbing core, such as a life jacket, a seat belt pad, and a disaster prevention hood, according to the present invention, has a thickness that is extremely small in deformation, i.e., crushing. It receives external forces dispersed over a wide area, and when a collision or other incident is encountered, a particularly strong impact load is applied to a local area, causing the area to turn red or dark, or the internal or skeletal It significantly contributes to minimizing or eliminating damage accidents as much as possible.Incorporates cores for absorbing shock such as life jackets, seat belt pads, disaster prevention hoods, etc. that meet the above demands This has a significant effect on achieving the intended purpose of providing safety equipment completely.
