  • Patent number: 9493095
    Abstract: A seat cushion is arranged on a riser. A strut is coupled, at lower end, to the rear end of the riser, and is provided at the back of the seat cushion. The seatback is secured to the strut, and is isolated from the seat cushion. The seatback and the seat cushion can therefore move, independent of each other. The seatback or the seat cushion, or both are lifted or lowered by a lifting/lowering means. Thus, the seatback and the seat cushion are lifted or lowered relative to each other. The lower half of the seatback, which supports the hips and lower ribs in the main, is made narrow than the upper half that supports the shoulder blades in the main. The seat cushion has, in the middle part of the rear end, a U-notch which loosely holds the narrow lower half.
