1. A rotating car seat mechanism, comprising:
a seat base, having a base frame and a sliding track, wherein the base frame secured to a floorboard of a car therein;
a sliding plate, securing to an upper side of the sliding track on the seat base, wherein the sliding plate is movable forward
and backward along the sliding track;
a rotating plate, having an axle inserting hole, wherein a top surface of the rotating plate is adapted for securing a conventional
car seat or a wheelchair; the rotating plate further having a guiding socket plate formed on a lower side thereof, wherein
a guiding socket with designated shape formed thereon defines a path having a segment with a large radius, a segment with
a smaller radius and a segment extending along a straight line;
an axle defining an axis of rotation, disposed near a rear end of the sliding plate and close to a car door; a thrust bearing
associated with the axle, and an axle cover configured on the upper side of the axle; wherein the axle insertion hole of the
rotating plate is set onto an upper side of the outer circumference of the axle, thereby enabling the rotating plate to hold
firmly against the thrust bearing; the axle cover is secured to an upper side screw aperture of the axle, thus allowing the
rotating plate to rotate on the axle about said axis of rotation on the upper side of the sliding plate; when the sliding
plate moves forward and backward on the sliding track, the rotating plate moves correspondingly by means of the axle;
a cylindrical pivot rod, having an outer circumference fitted into the guiding socket of the guiding socket plate; wherein
a bottom end of the cylindrical pivot rod is assembled to the base frame or secured to directly below on the car floorboard;
wherein the sliding plate is moved to an appropriate position inside the car when in operation, allowing an upper end of the
cylindrical pivot rod to be positioned at an exit of the guiding socket thereon; when the rotating plate is rotated towards
the car door, the cylindrical pivot rod slides into the guiding socket simultaneously; the rotating plate is continually pushed
until extended out of the car door, and because the movement of the guiding socket is driven by the fixed cylindrical pivot
rod, the rotating plate not only rotates on the axle, but the axle also drives the rotating plate forward, thereby enabling
the sliding plate and the axle to slide forward; this configuration allows a suitable degree of motion of the rotating plate
to exceed out of a narrow space of the car, whereas reversing the operation enables the rotating plate to return to the original
position.
