BACKGROO1~ T1~E rNVENTJ;ON
It is well known that there may be some inconveniency to open an autotnobile door with conventional hinge mechanism, which renders the door to rotate a pin close to the door's front internal edge, or its main movement being above rotation. When the door is opened in a Barking lot with another vehicle on the same side as the door to the discussed vehicle, said door someeimes can't be fully opened, otherwise said door may interfere with another vehicle.
Therefore most customers prefer a sliding rear door of a van to a rear door with conventional rotational mechanism when they buy a van.
But to a sedan or a ttvck, there is usually not enough space for a track guiding a rear door with sliding niechanisrn.
To a front door, there has never been a sliding mechanism with any kfnd ~pf vehicles commercially.

Reference to FIG. xU, the prese~tt invention is functionally the same of a planner four-bar-linkage if all axes of fear pins 2b, 28, 34 anti 32 are parallel in the space, with the A-pillar and a centerpoint 26 and another center point 3U det?ning the stationary or graurxd link: the door and center points 28 and 32 defining the apposite link; the first link lli and the second link ~U
are bath connecting the opposite link (the dear) to the stationary link (the door frame). These four links constitute a four bar-linkage with one degree of freedorra (DOF) for the door.
When said door 10 is fully opened, the ,gap between the rear edge; of said door 1i) and a B-pillar 6 should be big enough for an occupant of the vehicle to enter or exit the vehicle, and usually the rear edge of the door ID is closer to the A..pillar than that of the front edge of the door to the A-pillar. This is one of the main difference of the betvveen present invention and prior arts.
To span the door, att occupant just needs to push from a place inside the vehicle outwardly or pull from a place outside the vehicle also outwardly.
Td close the door, an occupant just need$ to push from a place outside the vehicle inwardly or pull from a place inside the vehicle also inwardly.
When the door is being opened or closed, said first link 18 rotates around the auci s of pin 2b and said second link 20 rotates around the axis of pin 30, while the second end of first link 18 and second end of second link 20 move the door 1Q to a desired location.

For the present invention with tilted direction of the pin 26, the door 10 is not moving horizontally when it is being opened, but rnovittg up simultaneously, therefore, the gag hetween the bottom edge of said door 10 and a top edge of said sill gives more space for entering or exiting the vehicle of occupant's legs.
The link 24 do not have to be caa~nected by pivotal means, bath ends of it can either or both be connected by a universal joints The axis of the gin 28 doesn't have to be parallel to that of the pin 26. We can consider the present invention in this way, if we look at the present invention along the axial direction of the pin 26 and we assume that the door frame 2 is grounded and the door is connected to the Boar frame just by the first link 18, pin 26 and pin 28, the first link X8 has one D17F (rotation around the axis of the pin z~), the door 10 has two D4F (one is the same of the first link I $, another is the rotation of the door itself around the axis of the pin 2~y, therefore the function of the second link 2U is to constrain vne I1C7F of the char, with this intend, the spherical center of the joint 30' should not he coincident with the axis of the gin 26 or its extension and should have a non zero normal distance from each ether; spherical center of the joint ~2' should not be coincident with the axis of the pin ~$ or its extension and should have a non zero normal distance from eacf~ ntt,er.
