Abstract

PURPOSE:To enable a seat cushion to be inclined in accordance with the inclining movement of a seat back by making both seat cushion and seat back turnably and pivotal connected. CONSTITUTION:A seat cushion A is pivotally mounted to bases C with pins 21 while a seat back B is pivotally mounted to the upper ends of arms 1 with pins 22. A supporting shaft 23 is projected at the rear end of the seat cushion A and both ends of the seat back B are pivotally attached to the shaft. The position at which the supporting shaft 23 is pivotally attached thereto is lower than the pins 21. The lower ends of the arms 1 are pivotally attached to the bases C respectively, and adjusted for the inclination by means of reclining devices D.

Conventional vehicle seats of this type simply tilt the ivy in the longitudinal direction, so this center of rotation corresponds to the hip point of the seated person, that is, the center of rotation of the torso and girth of the human body. The seats are far apart from each other, and as a result, each time the seat bar is tilted, the seated person is forced to sit up again due to back and buttocks shifting, compression of the lumbar vertebrae, etc. The basic structure is to rotatably support each of the seat cushion and seat back, and to connect the two rotatably, so that the seat cushion and the seat back can be rotated as the seat cushion tilts. The seat cushion is also tilted. That is, due to the tilting of the seatback, the lower part of the seat back and the rear part of the seat cushion are lowered and tilted (sinking), causing problems such as back displacement, hip displacement, compression of the lumbar vertebrae, etc. This is intended to prevent this.

As mentioned above, the vehicle seat of the present invention is a seat cushion which is rotatably pivoted around the base at the substantially central portion in the forward direction. Consists of a seat back rotatably attached to the upper end of the arm.
The rear end of the seat cushion and the lower end of the seat back are rotatably connected to each other, and a reclining device is provided across the lower end of the arm and the base to operate in conjunction with the tilting of the seat back. Since the seat cushion is tilted, the rear part of the seat cushion and the seat back sink as the seat back tilts. Therefore, unlike conventional products, the lumbar vertebrae of the seated person are not compressed or the seated person's back or buttocks shift due to the tilting movement of the seat back, so that a comfortable sitting position can be achieved and a seat with extremely good seating comfort can be provided.
