Door opening/closing hinge device
First Claim
1. A door opening/closing hinge device for a vehicle including an outer link, an inner link and a connecting link, wherein:
- (a) said outer link extends in a vehicle longitudinal direction on an outside of a door thickness space, a first end thereof being pivotably supported by a first vehicle pillar-side pin and a second end thereof being pivotably supported by a first door-side connecting pin;
(b) said inner link is disposed in the door thickness space at a position determined by shifting said outer link in an obliquely inside direction of the vehicle substantially in parallel at a closed position of the door to said outer link, a first end thereof being pivotably supported by a second vehicle pillar-side pin; and
(c) said connecting link is disposed substantially in parallel at a closed position of the door with said inner link, a first end of said connecting link being pivotably connected to a medial portion of said inner link by a pin and a second end thereof being pivotably supported at a point between said medial portion and the second vehicle pillar-side pin by a second door-side connecting pin located inwardly of the first door-side connecting pin and outwardly of said inner link.

Abstract
A vehicle door opening/closing hinge device comprises an outer link having one end connected to a first pillar pin and the other end connected to a first door pin, an inner link disposed longitudinally apart from the outer link and having one end connected to a second pillar pin, and a connecting link having one end connected to the other end of the inner link and the other end connected to a second door pin, so as to form a five joint link mechanism. The inner link is formed with a guide member having a slot engageable with a third door pin to control door opening positions. In the above door hinge device, since an angle subtended by the inner link and the connecting link is small at the door full closed position, it is possible to increase the thickness of the vehicle pillar for providing a more rigid pillar, widen the passenger getting in-or-out space at passenger'"'"'s feet at the initial door open position, and smoothly and widely open the door to the door full open position for providing a wider passenger'"'"'s space.
