Abstract

An apparatus for exchanging a driver'"'"'s seat with a passenger'"'"'s seat of a vehicle comprises seat bases on which a driver'"'"'s seat and a passenger'"'"'s seat are provided, a main body assembly provided between the seats, and a link mechanism for linking the main body assembly to the respective seat bases. Seat motor(s) and a main motor of the main body assembly are controlled so as to directly exchange the seats.

Claims

1. An apparatus for exchanging a driver'"'"'s seat with a passenger'"'"'s seat of a vehicle, comprising:

seat bases each provided on the driver'"'"'s seat and the passenger'"'"'s seat respectively, being movable on a portion of the floor of the vehicle and being rotatable by seat motors;

a main body assembly provided between the driver'"'"'s seat and the passenger'"'"'s seat and having a main motor for rotation of the main body assembly; and

link mechanisms each linking the respective seat bases to the main body assembly and having rotary points each provided at the center of the respective link mechanisms;

wherein,

the main body assembly is provided with rotating elements for rotating link arms of the link mechanisms so that included angles at the rotary points vary with rotation of the link arms.

2. The apparatus according to claim 1, wherein the main motor is constructed so that a vane is rotated about a rotating shaft of the main motor by hydraulic pressure of fluid.

3. The apparatus according to claim 2, wherein the fluid is supplied through a fluid line, which branches from a refrigerant line at each of inlet and outlet sides of a compressor for an air conditioner, and a reverse valve is provided on the fluid line to convert a direction of the refrigerant fed to the vane.

4. The apparatus according to claim 1, wherein the main body assembly comprises:

a cover;

a base coupled to the cover to define a space therebetween; and

a gear assembly comprising a driving gear coupled to a rotating shaft of the main motor and driven gears provided on both sides of the driving gear, wherein

the link arms of the link mechanisms are connected to the driven gears so as to be rotatable along with the driven gears.

5. The apparatus according to claim 4, wherein the main body assembly further comprises:

a clutch mechanism for moving up and down the driving gear so that the driving gear engages with or disengages from the driven gears, wherein

the driving gear is coupled or attached to the base of the main body assembly when the driving gear moves downwards.

6. The apparatus according to claim 5, wherein an actuator is provided at a predetermined position on each of the driven gears so as to hold the respective driven gears at a predetermined position.

7. The apparatus according to claim 5, wherein the clutch mechanism comprises:

a magnetic clutch secured to the cover with a coil wound in the magnetic clutch; and

a slider provided between the magnetic clutch and the rotating shaft of the main motor and splined to the rotating shaft of the main motor in such a way as to move in a longitudinal direction of the rotating shaft of the main motor, a lower end of the slider being secured to the driving gear.

8. The apparatus according to claim 7, wherein an upward moving distance of the slider is limited by the length of the slider.

9. The apparatus according to claim 7, wherein the driving gear and the driven gears comprise bevel gears, the driving gear being tapered upwards and the driven gears being tapered downwards.

10. The apparatus according to claim 1, wherein each of the driver'"'"'s seat and the passenger'"'"'s seat is provided with a locking part for locking the driver'"'"'s seat and the passenger'"'"'s seat to a predetermined position on the floor respectively.

11. The apparatus according to claim 1, wherein each of the driver'"'"'s seat and the passenger'"'"'s seat is provided with a position sensor for detecting a rotating angle of the driver'"'"'s seat and the passenger'"'"'s seat respectively.
