차량 시트의 안락감 평가용 더미 {DUMMY FOR COMFORT VALUATION OF VEHICLE SEAT}Dummy for comfort evaluation of vehicle seats {DUMMY FOR COMFORT VALUATION OF VEHICLE SEAT}

본 발명은 차량 시트의 안락감 평가용 더미에 관한 것이며, 상세하게는 차량 시트의 안락감 평가용 더미(dummy, 인체 모델)의 플래쉬(flesh, 피부, 살, 육체)에 관한 것이다.The present invention relates to a dummy for comfort evaluation of a vehicle seat, and more particularly to a flash (flesh, skin, flesh, flesh) of a comfort evaluation dummy (human body model) of a vehicle seat.

차량의 시트에 탑승객이 착좌하였을 때 그 안락감은 더미(인체 모델)에 의하여 평가하고 있으며, 상기 안락감의 평가시 더미는 탑승객(인체)과 유사한 골격 및 피부의 거동과 유사한 구조일 경우 그 안락감 평가를 양호하게 할 수 있게 되는 것이다.When the passenger sits on the seat of the vehicle, the comfort is assessed by the dummy (human body model), and when evaluating the comfort, the dummy evaluates the comfort when the structure is similar to the behavior of the skeleton and skin similar to the passenger (human body). It can be made favorable.

종래 시트의 안락감 평가용 인체 착좌 대체 장비가 특허문헌 1에 개시되어 있는바, 상기 특허문헌 1의 인체 착좌 대체 장비는 해부학적인 인체 골격 형상을 가지는 모델로 갈비뼈, 흉추, 요추, 미골, 골반이 연결되어 있고, 허벅지와 골반은 볼-소켓 조인트로 연결하며, 플래쉬는 반투명 단일층 실리콘 고무로 형성한 것이다.Conventional seat replacement equipment for comfort evaluation of the seat is disclosed in Patent Document 1, the human seat replacement equipment of Patent Document 1 is a model having an anatomical anatomical skeleton, ribs, thoracic spine, lumbar spine, coccyx, pelvis connected The thighs and pelvis are connected by ball-socket joints, and the flash is made of translucent single layer silicone rubber.

<특허문헌 1: US 6,206,703 B1><Patent Document 1: US 6,206,703 B1>

그러나 상기한 플래쉬는 단일층의 실리콘 고무로 형성하여 그 물성치를 동일하게 형성한 것임으로 인체의 피부 특성과 다르기 때문에 실제 탑승객이 시트에 착좌하였을 때 발생되는 하중분포 및 접촉 면적 등의 재현이 불가능하게 되어 안락감 평가의 신뢰성이 떨어지는 문제점이 있게 되는 것이다.However, since the flash is formed of a single layer of silicone rubber and has the same physical properties, it is different from the skin characteristics of the human body. Therefore, it is impossible to reproduce the load distribution and contact area generated when the passenger occupies the seat. There is a problem that the reliability of comfort assessment is poor.

본 발명은 상기한 실정을 감안하여, 더미의 피부를 다층 구조로 형성함과 아울러 각층의 물성치를 각각 다르게 형성하여 인체와 유사한 특성을 발휘할 수 있게 한 차량 시트의 안락감 평가용 더미를 제공하는 것을 목적으로 한다.SUMMARY OF THE INVENTION In view of the above circumstances, an object of the present invention is to provide a dummy for comfort evaluation of a vehicle seat in which the skin of the dummy is formed in a multi-layered structure and the physical properties of each layer are formed differently so as to exhibit characteristics similar to the human body. It is done.

상기한 목적을 달성하기 위하여, 본 발명은 인체 골격 형상의 외부에 형성하는 피부를 내층, 외층 및 스킨층의 적층 구조로 형성함과 아울러 상기 내층 및 외층은 탄성 계수가 각각 다른 점탄성재로 형성하고, 상기 스킨층은 직포로 형성하여서 된 것이다. In order to achieve the above object, the present invention forms a skin formed on the outside of the human skeleton shape in a laminated structure of the inner layer, the outer layer and the skin layer, and the inner layer and the outer layer are each formed of a viscoelastic material having different elastic modulus and The skin layer is made of a woven fabric.

이상과 같이 본 발명은 더미의 피부를 내층, 외층 및 스킨층의 적층 구조로 형성함과 아울러 상기 내층 및 외층은 탄성 계수가 각각 다른 점탄성재로 형성하여 인체와 유사한 특성을 발휘토록 함으로써 탑승객이 실제 시트에 착좌할 때 발생하는 하중 분포 및 접촉 면적 등의 재현을 할 수 있기 때문에 안락감 평가의 신뢰성을 증진할 수 있는 것이다.As described above, in the present invention, the skin of the dummy is formed into a laminated structure of an inner layer, an outer layer, and a skin layer, and the inner layer and the outer layer are formed of viscoelastic materials having different elastic modulus, respectively, to exhibit characteristics similar to those of the human body. Since the load distribution and the contact area generated when seated on the seat can be reproduced, the reliability of the comfort evaluation can be improved.

또한 스킨층은 피부의 형상을 유지함과 아울러 내층 및 외층의 표면 장력을 양호하게 유지함으로써 점탄성 특성 유지를 양호하게 하여 수명 연장 등을 할 수 있는 것이다.In addition, the skin layer can maintain the shape of the skin and maintain the surface tension of the inner layer and the outer layer in a good manner so that the viscoelastic properties can be maintained and the life can be extended.

상기 내층(14)은 실리콘 고무 또는 폴리우레탄 폼 등의 점탄성재로 형성하고, 그 탄성 계수는 0.012~333Mpa가 바람직하며, 상기 내층(14)은 인체 특히 대퇴부의 근육층의 기능을 하는 것이다.The inner layer 14 is formed of a viscoelastic material such as silicone rubber or polyurethane foam, and its elastic modulus is preferably 0.012 to 333 Mpa, and the inner layer 14 functions as a muscle layer of the human body, in particular, the thigh.

상기 외층(15)은 상기 내층과 동일한 재료로 형성하고, 그 탄성 계수는 상기 내층보다 작은 0.02Kpa~4Mpa가 바람직하며, 상기 외층(15)은 인체의 특히 대퇴부의 지방층의 기능을 하는 것이다.The outer layer 15 is formed of the same material as the inner layer, and its elastic modulus is preferably 0.02 Kpa to 4 Mpa smaller than the inner layer, and the outer layer 15 functions as a fat layer of the human thigh in particular.

상기 스킨층(16)은 직포로서, 천연 또는 인공 섬유 직포를 사용하고, 상기 스킨층(16)은 상기 내층(14) 및 외층(16)의 형상을 유지함과 아울러 표면 장력을 양호하게 유지하는 것이다.As the skin layer 16 is a woven fabric, a natural or artificial fiber cloth is used, and the skin layer 16 maintains the shape of the inner layer 14 and the outer layer 16 and maintains a good surface tension. .

상기 피부(13)의 전단응력은 11.7~33.8Kpa의 범위가 바람직하고, 또한 포아송비는 0.4~0.6이 바람직하다.The shear stress of the skin 13 is preferably in the range of 11.7 to 33.8 Kpa, and the Poisson's ratio is preferably 0.4 to 0.6.
