의자용 방석시트{Cushion sheet for a chair}Cushion sheet for a chair}

본 발명은 의자용 방석시트에 관한 것으로서, 더욱 상세하게는 방석시트의 중앙부는 인체 엉덩이의 곡선을 따라 둥글게 오목한 형상을 유지하고, 인체 허벅지의 대퇴부가 위치되는 전방부에는 부분적으로 요홈부를 형성하는 한편, 전방부의 중앙과 후방부는 돌출되게 형성함으로써 사용자가 방석시트에 착석시 방석시트 자체의 탄성과 전방부의 중앙 및 후방부에 형성된 돌출부에 의해 인체의 엉덩이를 감싸게 되어 인체의 하체를 고정시켜 안락함을 줄수 있을 뿐만 아니라, 전방부에 부분적으로 형성된 요홈부에 의해 인체 대퇴부의 압박감을 해소하여 혈액순환을 원할하게 함으로써 장시간 의자에 앉아 있을 경우에도 피로감을 덜 느낄 수 있도록 하는 의자용 방석시트에 관한 것이다.The present invention relates to a cushion seat for a chair, and more particularly, the center portion of the cushion seat maintains a rounded concave shape along the curve of the human hip, and partially forms a recess in the front portion where the thigh of the human thigh is located. When the user is seated on the cushion seat, the center and the rear part of the front part are protruded so that the user's hips are fixed by the elasticity of the cushion seat itself and the protrusions formed at the center and the rear part of the front part to fix the lower body of the body. In addition, the present invention relates to a seat cushion seat for allowing a user to feel less fatigue even when sitting in a chair for a long time by relieving the pressure of the human thigh by a recess part formed at the front part.

일반적으로 의자용 방석시트는 신축성이 양호한 폴리우레탄을 사용하고 일체로 사출 성형하여 주로 제조하고 있으며, 이러한 종래 의자용 방석시트의 구조는 도 1에 도시된 바와 같이 통상적으로 사각형상의 몸체(1) 중앙부에는 단순히 인체의 엉덩이 부분이 안치되는 오목형태의 착석부(2)가 형성되며, 상기 착석부(2)의 외측에는 상대적으로 볼록하게 성형된 돌출부(3)가 형성된 구조를 이루고 있다.In general, the seat cushion seat for the chair is mainly manufactured by using a good stretch polyurethane and integrally injection molding, the structure of such a conventional seat cushion seat for a conventional rectangular body (1) as shown in Figure 1 The concave seating portion 2 is simply formed in which the hip portion of the human body is placed, and the outer side of the seating portion 2 has a structure in which a relatively convexly formed protrusion 3 is formed.

이와 같은 구조를 갖는 종래 의자용 방석시트는 사용자가 의자 위에 설치된 방석시트에 앉을 경우 엉덩이 부분이 오목형태로 형성된 착석부(1)에 안치되나, 상기 착석부(1) 외측에 상대적으로 형성된 돌출부(3)가 인체 허벅지의 후면인 대퇴부뒷면을 가압하여 혈액순환을 저해함으로써 인체의 피로를 가중시키는 문제점이 있는 것이다.Conventional seat cushion seat having a structure as described above is seated in the seating portion (1) formed in the concave shape of the hip portion when the user sits on the seat seat installed on the chair, a protrusion formed relatively to the outside of the seating portion (1) 3) has a problem of increasing the fatigue of the human body by inhibiting blood circulation by pressing the back of the thigh that is the rear of the human thigh.

즉, 인체에 있어 대퇴부(大腿部:thigh)는 흔히 말하는 "넓적다리 부위(허벅다리 부위)"를 가르키는 해부학적 명칭으로 고관절(股關節)과 슬관절(膝關節) 사이를 말하며, 해부학적으로는 대퇴골이 중심이 되어 그것을 둘러싼 여러 개의 잘 발달된 근육, 즉 신근군(伸筋群)·내전근군(內轉筋群)·굴근군(屈筋群), 근육 사이에는 대퇴동맥·대퇴정맥의 2가지 혈관, 좌골신경·대퇴신경 등이 주로 상하로 뻗어 있고 그것을 피부가 감싸고 있다. 즉, 대퇴는 방대한 체부이기는 하지만 내용은 비교적 단순하며, 그 주체를 이루는 것은 뼈와 근육이다.That is, in the human body, the thigh (thigh) is an anatomical name for the commonly known "thigh site (thigh site)" refers between the hip joint and the knee joint. The femur is centered and the well-developed muscles surrounding it, namely the extensor muscle group, the adductor muscle group, the flexor group, and the muscles of the femoral artery and the femoral vein. Two blood vessels, sciatic nerve, femoral nerve, etc. are mainly stretched up and down and the skin is wrapped. In other words, the femur is a huge body, but the contents are relatively simple, and the subjects are bones and muscles.

이러한 대퇴부는 앞면과 뒷면으로 구분된다. 즉, 대퇴부 앞면(Thigh)은 대퇴부 앞면을 감사고 있는 커다란 근육이 대퇴 사두근이고 내측광근, 중간광근, 대퇴직근으로 구성되어 있고, 봉공근이나 장요근에도 관련된다. 또한 대퇴부 뒷면 (Hamstring)은 대퇴이두근이 중심적으로 기능하는데 이와 평행하는 반건양근이나 작은 반막양근,박근 등도 협동근으로 존재하여 대퇴부 뒷면을 형성하고 있으며, 대퇴부 앞.뒷면에 존재하는 각 근육에는 수 많은 혈관이 형성되어 있다.These thighs are divided into front and back. That is, the thigh front (Thigh) is a large quadrilateral muscles that audit the front of the femoral quadriceps, consisting of the medial, medial, femoral rectus muscle, and also related to the bark root and intestinal psoas muscle. In addition, the back of the femur (Hamstring) is the central function of the biceps femur, and the semi-pectoral muscles, small half-arm muscles, and the pectoral muscles parallel to each other form cooperative muscles to form the back of the thigh, and each muscle in the front and back of the thigh Blood vessels are formed.

따라서, 의자 이용자가 방석시트(10)에 앉을 경우 착석부(2)에 의해 상대적으로 돌출된 돌출부(3)에 의해 대퇴부 뒷면에 존재하는 각 근육을 압박하게 되고, 이로 인해 혈관이 좁아지게 되어 혈액순환이 어려워지게 됨으로써 인체의 피로를 가중시키는 문제점이 있는 것이다.Therefore, when the user of the chair sits on the cushion seat 10, the muscles existing on the back of the thigh are pressed by the protrusions 3 protruding relatively by the seating unit 2, thereby narrowing blood vessels and thus blood. The circulation becomes difficult, so there is a problem that increases the fatigue of the human body.

특히, 장시간 의자에 앉아 있는 학생이나 직장인은 상기의 문제점으로 인해 피로를 쉽게느끼고 만성피로에 시달릴 뿐만 아니라, 혈액순환장애로 인하여 또 다른 질병을 가져오게 됨으로써 혈액순환 장애를 해소할 수 방안과 의자의 신뢰성을 높일 수 있는 방안이 절실히 요구되고 있는 것이다.In particular, students or office workers who sit in chairs for a long time feel tired and suffer from chronic fatigue due to the above problems, and also bring about another disease due to blood circulation disorders, which can solve blood circulation disorders. There is an urgent need for a way to increase reliability.
