Fatigue-reducing helmet with vibration damping function

Abstract

To provide a helmet which reduces and prevents fatigue of the body and brain caused by vibration and shock experienced by a driver or a worker and maintains working efficiency and quality in a good condition.SOLUTION: A dynamic vibration absorber 1 comprises an internal vibration damping structure 2, a shock damping structure 4, and an exterior material 6. The internal vibration damping structure 2 contains a fluid 3, and its vibration damping characteristics can be adjusted by the characteristics, amount, number, variation, and mutual interference of the contained fluid. The intermediate shock damping structure 4 has a gas 5 or a space 5 and houses the internal vibration damping structure 2. The cushioning and damping performance of the shock damping structure 4 can be adjusted by the material properties such as rigidity of the structure, physical properties such as thickness and number, and volume, shape, and internal pressure of the contained gas space, and can be adapted to tasks and environments, such as driving, operating vibrating tools, and vibration environments. The exterior material 6 houses the internal vibration damping structure 2 and the intermediate cushioning and damping structure 4, and has resistance strength in consideration of structural compatibility with a helmet to serve as a dynamic vibration absorber for transported cargo.SELECTED DRAWING: Figure 3

Description

[Technical field]

[0001] The present invention relates to a fatigue-reducing helmet, and more particularly to a fatigue-reducing helmet with a vibration-damping function that can control and reduce the impacts and vibrations that a driver or worker receives while driving or working, thereby maintaining good brain activity and health. [Background technology]

[0002] Destruction of objects occurs due to fatigue damage caused by minute vibrations and large impacts. The same is true for humans, with many accidents and loss of concentration while driving or working, which is a burden on industry. Therefore, this invention was developed with the aim of reducing vibration during operation.

[0003] The inventor invented a cargo material in "Dynamic vibration absorber for transporting cargo and a transport method using the same" and achieved great results. Based on the results, he devised a general-purpose small structure and applied it to helmets. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent No. 06184206 [Patent Document 2] Patent Publication No. 2020-176266 Summary of the Invention [Problem to be solved by the invention]

[0005] A helmet that could withstand the vibrations and shocks that occur while driving was needed to improve driving performance and prevent accidents. The object of the present invention is to provide a fatigue-reducing helmet with a vibration-damping function that has the ability to reduce or prevent brain fatigue caused by vibrations and impacts that a driver experiences while driving, thereby maintaining good driving conditions. [Means for solving the problem]

[0006] By installing a general-purpose small dynamic vibration absorber inside the helmet, we discovered a structure that reduces both vibration and impact. Effect of the Invention

[0007] The present invention provides a fatigue-reducing helmet with a vibration-damping function that reduces or prevents brain fatigue caused by vibrations received by drivers and workers while driving or operating, and maintains good driving and work quality, thereby reducing transportation losses in Japanese industries.

Claims

[Claim 1] This relates to the internal structure of the shell of a head protection helmet, and to a head protection helmet that reduces vibration and impact by using a structure that functions as a small, general-purpose dynamic vibration absorber. The small general-purpose dynamic vibration absorber function of the fatigue reduction helmet with vibration damping function is composed of an internal vibration damping structure, an intermediate layer with a cushioning function, and an exterior material to house it. The internal vibration-damping structure is made up of a collection of small cellular tissues or small containers that contain fluids and gases. The middle layer, which has a cushioning function, is a soft tissue or gas-filled cellular tissue with a cushioning function that supports and contains the internal vibration-damping structure. The exterior material holds and contains the functions of the structural materials, and these structures have the frictional retention force that transmits the vibration-damping function inside the helmet. By utilizing a general-purpose flexible dynamic vibration absorber, a low-cost and feasible method has been discovered to constantly reduce brain fatigue in addition to providing emergency head protection, resulting in a fatigue-reducing helmet with vibration control functions that improve the work efficiency of drivers and workers and reduce the causes of health damage and accidents.
