ABSTRACT:
The invention concerned relates to a car seat having one side frame each mounted on the upper rails of a pair of left and right seat slide adjusters for the entire seat and backrest, with a seat cushion frame installed so as to allow free sliding in either direction, and a rack contained either in one of these side frames or one of these seat cushion frames, while a shaft with a pinion which engages with said rack is installed in the other frame, together with a lock mechanism that selectively restricts the rotation of the aforementioned pinion. Due to the aforementioned peripheral mechanism consisting of a rack and pinion and the lock mechanism, this car seat allows the seat cushion to be slid and adjusted independently towards or away from the backrest of the seat easily and continuously and also enables the seat cushion to be locked securely in place at the desired position.
