Description

의자 틸팅장치Chair tilting device
본 발명은 의자 틸팅장치에 관한 것으로서, 더욱 상세하게는 등판부가 착석자의 고관절 중심으로 회동하여 자세 변형에 요추를 받쳐 척추의 안정화를 꾀하는 동시에 착석자의 높낮이 위치 변동을 최소화시킴으로써 착석자의 시선의 안정화를 꾀하도록 하는 의자 틸팅장치에 관한 것이다.The present invention relates to a chair tilting device, and more particularly, the back part rotates around the hip joint of the seated person to support the lumbar spine for postural deformation, thereby stabilizing the spine and minimizing the height change of the seated person's gaze. It relates to a chair tilting device to be.
일반적으로, 의자는 사용자의 둔부를 지지하는 좌판과, 사용자의 등을 지지하는 등판과, 그리고 좌판과 등판을 지지하는 베이스를 포함한다.In general, a chair includes a seat plate supporting the user's buttocks, a back plate supporting the user's back, and a base supporting the seat plate and the back plate.
이를 통해, 사용자가 등을 뒤로 젖힐 경우 등판도 따라서 뒤로 젖혀지도록 등판을 틸팅시키는 기술이 상당수 개발된 상태이고, 사용자의 척추에 무리를 주지 않도록 좌판과 등판을 함께 틸팅시키는 기술 또한 여러 각도로 개발되고 있는 상태이다. As a result, a number of technologies have been developed to tilt the back so that the back is also flipped when the user tilts the back. Also, the technology of tilting the seat and the back together so as not to overwhelm the user's spine is developed at various angles. It is in a state.
한편, 등판과 좌판을 함께 틸팅시키는 종래의 틸팅 장치들에 대해 설명하면 다음과 같다.Meanwhile, the conventional tilting apparatuses for tilting the back plate and the seat plate together will be described.
