Fatigue reduction vehicle seat having vibration control function

Abstract

To provide a vehicle seat having a function which reduces or prevents fatigue of a body and a brain caused by vibration impact received by a driver or an occupant during traveling and keeps driving and riding qualities in good states.SOLUTION: A dynamic vibration absorber 1 provided with a cushioning function comprises: an internal vibration control structure 2; an impact damping structure 4; and a sheath material 6. The internal vibration control structure 2 incorporates a fluid 3 therein. Vibration control features may adjust characteristics, an amount, a number, variations, and mutual interference of the incorporated fluid. The impact damping structure 4 in a middle layer has a gas 5 or a space 5 and houses the internal vibration control structure 2. Characteristics of cushioning and damping functions of the impact damping structure 4 can be adjusted by material characteristics, such as rigidity of the structure, physical properties, such as a thickness and a number, and a volume, a shape, and an internal pressure of a gas space included therein. The sheath material 6 houses the internal vibration control structure 2 and the impact damping structure 4 at the middle layer, and is formed considering structural adaptability with a vehicle seat to achieve a function of the dynamic vibration absorber for transported loads.SELECTED DRAWING: Figure 3

Description

[Technical field]

[0001] The present invention relates to a fatigue-reducing vehicle seat, which is a fatigue-reducing vehicle seat with a vibration-damping function that controls and reduces the impact and vibration that a driver or passenger receives while driving, 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 made with the aim of reducing vibrations during driving and operation. The inventor invented a cargo material in "Dynamic vibration absorber for transporting cargo and a transportation method using the same" and achieved great results.

[0003] Based on this experience, a general-purpose small structure was devised and applied to vehicle seats. [Prior art documents] [Patent documents]

[0004] [Patent Document 1] Patent Publication No. 06184206 [Patent Document 2] Patent No. 2022-172205 Summary of the Invention [Problem to be solved by the invention]

[0005] Vehicle seats that can withstand vibrations and shocks while driving are necessary to improve driving performance and prevent accidents. They are also important for maintaining the physical and mental health of the passengers who are the targets of the service. The object of the present invention is to provide a fatigue-reducing vehicle seat with a vibration-damping function that reduces or prevents brain fatigue caused by vibrations and impacts that drivers and passengers experience while driving, thereby maintaining good driving conditions and maintaining the physical and mental health of passengers while on board. [Means for solving the problem]

[0006] By inventing a general-purpose small dynamic vibration absorber, we were able to find a structure that can be applied inside a vehicle seat to reduce both vibration and shock. Effect of the Invention

[0007] The present invention provides a fatigue-reducing vehicle seat with a vibration-damping function that reduces or prevents brain fatigue caused by vibrations received by drivers and passengers while driving, and maintains good driving and riding quality, thereby reducing transportation losses in the Japanese industry.
