Description

럼버서포트용 컴포트매트Comfort mat for lumber support
본 발명은 자동차 시트 내부에 설치되어 탑승자의 허리 부위를 지지하는 럼버서포트용 컴포트매트에 관한 것이다.The present invention relates to a lumber support comfort mat installed inside the vehicle seat to support the waist of the occupant.
전체적으로 럼버서포트를 포함한 시트는 운전 중 안전 운전과 직접 관계가 있다는 점에서 일반 좌석과 엄격히 구분되는 중요함을 가지고 있다.Overall, seats with lumber support have the importance of being strictly distinguished from regular seats in that they are directly related to safe driving while driving.
오늘날의 시트는 움직이는 기구의 발달과 인류문화의 향상으로 인하여, 단순 목적인 인체를 지지하는 것에 그치지 않고 다양한 목적으로 많은 발전이 이루어지고 있다. 이에 대하여 자동차 시트가 갖추어야 할 중요한 요건은 다음과 같다.Due to the development of moving mechanisms and the improvement of human culture, today's sheets have been developed for various purposes, not just for supporting the human body, which is a simple purpose. In this regard, the important requirements for the car seat are as follows.
먼저, 안전성을 들 수 있으며, 외부의 물리적 변화로부터 인체의 손상을 최소화하기 위해 견고하고, 차량 수명의 내구성을 구비하여야 한다. First, safety may be mentioned, and in order to minimize damage to a human body from physical changes from the outside, it should be robust and have durability of a vehicle life.
또한, 안락성면에서 장시간 탑승시 피로가 적고 쾌적성을 유지(접촉성, 충격의 흡수, 착좌 자세 및 쿠션성 등)해야 하며, 편의성의 측면에서 탑승자의 여러 신체 조건에 따라 시트를 조절하는 기능을 갖추고 이의 조절이 용이하여야 한다.In addition, in terms of comfort, fatigue should be maintained for a long time while maintaining comfort (contact, shock absorption, seating position and cushioning), and in terms of convenience, the seat can be adjusted according to various physical conditions of the passenger. Its control should be easy.
그리고 디자인의 관점에서 안정감이 있는 외관 및 오랜 기간 보고 사용해도 싫증나지 않도록 디자인을 고려해야 하고, 경제성에서도 차량의 특성에 적합한 상품성 및 저비용을 실현해야 한다. From the viewpoint of design, the design should be considered so that it does not get tired even after seeing and using it for a long time, and economic feasibility and low cost should be realized for the characteristics of the vehicle.
이상과 같이 자동차 시트는 안전성, 안락성, 편리성, 디자인 등이 종합적으로 고려된 것이다 보니 일반 좌석과는 달리 인간공학과 감성공학이 깊게 반영되고 있다. As described above, the car seat is considered to be a comprehensive consideration of safety, comfort, convenience, and design. Therefore, unlike general seats, ergonomics and emotional engineering are deeply reflected.
시트쿠션은 체중을 이상적으로 배분하여야 하고 충격과 진동을 잘 흡수하여야 한다. 체중의 75% 정도는 둔부에 의해 지지되며, 특히 좌골결절상 부분에 체중의 35% 정도가 집중되며, 이로 인한 혈액 순환 장애로 통증이나 마비 증세를 유발할 수도 있다. 또한 장시간 운전은 하체의 혈액 순환을 방해하여 발을 부어 오르게 한다.Seat cushions should ideally distribute weight and absorb shock and vibration well. About 75% of the weight is supported by the buttocks, especially about 35% of the weight in the sciatic nodules, which can cause pain or paralysis due to poor circulation. Prolonged driving also interferes with blood circulation in the lower body, causing the feet to swell.
이때, 럼버서포트는 허리에 가해지는 압력을 지지하여 장시간 운전시 피로감을 해소하는 보조기구이다. 럼버서포트는 골반을 지지하여 뒤쪽으로 넘어가는 것을 막아주며 허리 쪽의 척추를 지지하고 상체를 지지하는 역할을 한다.At this time, the lumber support is an auxiliary device to support the pressure applied to the waist to relieve fatigue during long time driving. Lumber support supports the pelvis and prevents it from going backwards, and supports the spine at the waist and the upper body.
그런데, 럼버서포트를 구성하는 부품 중 직접 압력을 받는 부분인 컴포트매트의 경우, 탑승자에 의해 하중이 가해졌을때 변형이 많이 일어나므로, 하중을 흡수할 수 있도록 탄성을 갖는 한편, 적절한 강성을 유지해야 할 필요가 있다.However, in the case of the comfort mat, which is a part directly under pressure among the components constituting the lumber support, since deformation occurs a lot when a load is applied by the occupant, it is necessary to have elasticity to absorb the load and maintain proper rigidity. Needs to be.
또한, 현재 고급차종의 경우에는 시트 내부에 차량 공조용 덕트가 연결되어, 냉기 또는 온기의 공급이 가능하게 구성되는데, 플레이트 형상의 컴포트매트로 인해 탑승자의 등 부위가 차량 공조용 덕트로부터 차단되어 냉·난방효율이 저하되는 문제가 있다.In addition, in the case of high-end models, the air conditioning duct is connected to the inside of the seat, so that cold or warm air can be supplied, and the back portion of the occupant is blocked from the air conditioning duct due to the plate-shaped comfort mat. • There is a problem that the heating efficiency is lowered.
