Abstract

A device for tilting and swiveling a seat of a vehicle is provided. The device performs a tilting operation for relaxation by cooperation of a seat back and a seat cushion as well as a swiveling operation for rotating the seat in an indoor direction for conversion between passengers or rotating the seat in an outdoor direction for getting on and off vehicle assistance.

First claim

What is claimed is:

1. A device for tilting and swiveling a seat of a vehicle, comprising:
a seat cushion frame and a seat back frame integrally connected with each other;
a fixing plate mounted on a fixed rail mounted at a floor panel;
a rotating plate stacked and mounted on the fixing plate to be rotatable;
a first side bracket mounted at both sides at a front end portion of the rotating plate;
a second side bracket having a guide aperture formed to be inclined downwardly toward the front to allow a guide pipe formed at both sides of a lower end of the seat back frame to be inserted into the guide aperture to be moved, and being mounted at both sides at a rear end portion of the rotating plate; and
a tilting drive device installed between the seat cushion frame and the first side bracket, and raising or lowering a front end portion of the seat cushion frame.

2. The device for tilting and swiveling the seat of the vehicle of claim 1 , wherein a movable rail is mounted to be movable on the fixed rail at both sides of a lower surface of the fixing plate.

3. The device for tilting and swiveling the seat of the vehicle of claim 1 , further comprising:
a center rotating pin formed at a central position of the fixing plate to couple with a hinge to the rotating plate; and
guide pins formed at four sides of the rotating plate.

4. The device for tilting and swiveling the seat of the vehicle of claim 3 , further comprising:
a hinge aperture formed at a central position of the rotating plate, wherein the center rotating pin is fastened to the hinge aperture; and
arc-shaped guide apertures formed at four sides of the rotating plate, wherein the guide pins of the fixing plate are inserted into the arc-shaped guide apertures.

5. The device for tilting and swiveling the seat of the vehicle of claim 4 , wherein the arc-shaped guide apertures are formed with an arc length that limits the rotation angle of the rotating plate to about 90°.

6. The device for tilting and swiveling the seat of the vehicle of claim 4 , further comprising:
a first motor mounted at a lower portion of the fixing plate, wherein one of the guide pins is adopted as a pinion connected to the output shaft of the first motor; and
a sector gear engaged with the pinion is formed in one of the arc-shaped guide apertures.

7. The device for tilting and swiveling the seat of the vehicle of claim 1 , wherein the tilting drive device includes:
a fan-shaped gear fastened with a hinge to a front end portion of the first side bracket;
a second motor mounted at an inner position of a rear end portion of the first side bracket;
a drive gear connected with the output shaft of the second motor, mounted at a rear end portion of the first side bracket and engaged with the fan-shaped gear; and
a support pipe attached at a front lower portion of the seat cushion frame and fastened with a hinge to the fan-shaped gear at both sides thereof.

8. The device for tilting and swiveling the seat of the vehicle of claim 7 , wherein a clamp into which the support pipe is inserted and penetrates to be rotatable and movable back and forth, is mounted at a front lower portion of the seat cushion frame.

9. The device for tilting and swiveling the seat of the vehicle of claim 7 , wherein the first side bracket includes:
a rotation support plate fastened with a hinge to the fan-shaped gear; and
a rigidity reinforcing plate having a height lower than that of the rotation support plate and being vertically bent inward.

10. The device for tilting and swiveling the seat of the vehicle of claim 7 , wherein a mounting end for mounting the second motor is formed to further extend at a rear end portion of the rigidity reinforcing plate of the first side bracket.
