ABSTRACT:
FIELD OF THE INVENTION
The present invention relates to a seat cushion of an automobile, more particularly a full floating device of a rear seat cushion for an automobile, which can fully adjust the angle of the rear seat cushion and can eliminate inconvenience caused by the wheel housing protruding into the inner space from the rear side of the automobile.
BACKGROUND OF THE INVENTION
Generally, both sides of the rear seat cushion of the automobile contacts with the wheel housing in which a tire is positioned and the rear seat cushion cannot adjust the angle thereof. Then the wheel housing protrudes into the inner space from the side body of the automobile. Therefore, when the rear seat is fully occupied, the side passenger does not feel well since the wheel housing contacts the waist of the passenger.
Furthermore, the passenger who may be an elderly person or a small child can get injured by the wheel housing protruding into the inner space from the side body of the automobile when the automobile collides with other automobile etc.
SUMMARY OF THE INVENTION
The object of the present invention is to provide a full floating device of a rear seat cushion for an automobile that can adjust the angle thereof and can make the passenger comfortable.
The present invention comprises a fixed frame fixed on a floor panel of an automobile, a pivot frame to which the end of the supporting bracket is linked by a pivot pin and on which a seat cushion is mounted, and an angle adjusting means pivoting the rear end of the pivot frame about the pivot pin in order to adjust the inclination of the seat cushion mounted on the pivot frame.
The angle adjusting means comprises a first pivot arm to which the rear end of the fixed frame is pivotally linked; a second pivot arm to which one end of the first pivot arm and the rear end of the pivot frame are pivotally linked; a spring connected between a pivot shaft and a seat cushion frame so that the second pivot arm can be pivoted by the elastic force of the spring; and a lock release means for releasing the locking state of the pivot frame by the elastic force of the spring.
The lock release means comprises a stopper to which the pivot frame is pivotally linked and having a teeth portion engaged with a teeth portion formed on the second pivot arm; a cam to which the pivot frame is pivotally linked and pushing a stopper so that the teeth portion of the stopper is disengaged with the teeth portion of the second pivot arm; a lever pivotally linked to the pivot frame; a link rotating the cam so that the teeth portion of the stopper and the teeth portion of the second pivot arm are selectively engage or disengaged each other by pivoting the lever, and a torsion spring mounted between the stopper and the pivot frame for giving a torque to the lever and returning it to the original position.
