Disclosed in the present invention are a brake actuator and a power swivel seat having the same, which are installed along with a rotating actuator to prevent the rotating gap of a swivel seat, and may improve safety by guaranteeing the stable strength when an excessive load is generated due to the collision of a vehicle and the like. To this end, the brake actuator and a power swivel seat having the same may comprise: a fixing frame installed in the vehicle interior; a rotating frame which is rotationally installed with respect to the fixing frame; a rotating actuator which is gear-coupled to a ring gear which is concentrically arranged with respect to the center of rotation of the fixing frame to rotationally drive the rotating frame; a shaft rotating gear which has a circumferential mounting surface; a brake roller which is installed by placing a brake spring therebetween with respect to the mounting surface of the shaft rotating gear; a lever rotating block having an inclined protrusion unit; an unlocking block having an inclination accommodating unit which may come in rotational contact with the inclination protrusion unit of the lever rotation block and an axial protrusion unit which may come in contact with the brake roller; and a brake ring having a restriction surface unit and a release surface unit which may or may not come in contact with the brake roller.

    본 발명은 회전용 액츄에이터와 함께 설치되어 스위블 시트의 회전 유격을 방지하고 차량의 충돌 등 과도한 하중 발생시 안정적인 강도의 확보를 통해 안전성을 향상시킬 수 있는 브레이크용 액츄에이터 및 이를 갖춘 파워 스위블 시트를 개시한다. 전술한 브레이크용 액츄에이터 및 이를 갖춘 파워 스위블 시트는 차실내에 설치되는 고정프레임, 고정프레임에 대해 회전 가능하게 설치되는 회전프레임, 고정프레임의 회전중심에 대해 동심원상으로 배치되는 링기어와 치결합되어 회전프레임을 회전 가능하게 구동하는 회전용 액츄에이터, 원주방향 안착면을 갖춘 샤프트회전기어, 샤프트회전기어의 안착면에 대해 브레이크스프링을 사이에 두고 설치되는 브레이크롤러, 경사돌기부를 갖춘 레버회전블록, 레버회전블록의 경사돌기부와 회전접촉 가능한 경사수용부 및 브레이크롤러와 접촉 가능한 축방향돌기부를 갖춘 언록킹블록, 및 브레이크롤러와 접촉 또는 비접촉 가능한 구속면부와 해제면부를 갖춘 브레이크링을 구비한다.
