PURPOSE:To make a safety seat effectively against an impact force by locking the rotatable support of a seat base at the lower rear side of the seat and the reclining adjustment device of the seat at its lower front side. CONSTITUTION:A seat 2 has an L-shaped member 5, extending along its bottom and back. Both right and left L-shaped frames 5a and 5b have a penetration hole 10 near their bent part, and a rotatably movable axis 11 is fixed to the rear side of a base 3 correspondingly, thereby making the seat 2 movable rotatably about the said axis 11. An adjustment fitting 12 is rotatably connected near the front end of the L-shaped frame 5 and an adjustment hole 14 is formed on its side wall. A gearing axis 15 is provided forward of the base 3 correspondingly, penetrating through the adjustment hole 14. Also, a spring 16 is so provided as to work for forcing the rotation of the adjustment fitting 12 at all times in one direction. |
