Abstract
Abstract The present invention relates to a reclining seat wherein a latch plate is pivotably mounted on an outer side of seat-back frame, and a releasable means is provided for fixing and unfixing the latch plate with respect to the seat-back frame, and an oil cylinder with a variable effective length is provided between a shaft mounted on said latch plate and a pin formed at the bottom of a seat cushion frame. The present reclining seat allows the adjustment and set of the angle of inclination of a seat-back continuously over a wide range of angles, and permits the release of said set in a simple way when the seat back is to be inclined either forwardly or backwardly. When the seat back is to be returned back to the previous position from such forwardly or backwardly inclined position, it is only required to return the seat-back as it will automatically lock in the previously set position.
