A door hinge device for a vehicle is capable of facilitating two doors to be simultaneously or independently opened or closed in a state in which rotation trajectories of the doors are ensured as a hinge bar connected to a carrier of a speed reduction unit through a hinge shaft and a rack and a pinion connected to a rotation shaft of a sun gear set a rotation amount of the doors during a process in which a hinge unit of the door moves along a rail in a diagonal direction toward the outside of a vehicle body in a vehicle including no B pillar.

In a door hinge device for vehicles, in a vehicle without a B pillar, a hinge slider connected to a hinge portion of a door slidably moves in an external diagonal direction of a vehicle body along a rail in a case to secure a rotational trajectory of the door, and then a first striker configured in the hinge slider is restrained to a hinge latch unit fixed onto the rail inside the case in association with an action of a second striker provided at one side of the door to fix a slide movement location of the hinge slider, stably achieving an opening/closing operation of the door.

In a door hinge device for the vehicle, in the vehicle without a B pillar, as the hinge slider connected to the hinge portion of the door moves in the diagonal direction of the vehicle body along the rail by the driving torque of the motor inside the case, each door may be independently opened or closed while securing the rotation trajectory of the door.

A vehicle door device includes first and second link arms having a first rotary coupling point with respect to a vehicle body and a second rotary coupling point with respect to a front door of a vehicle. The front door is opened toward a vehicle front side based on an operation of a link mechanism formed of the first and second link arms. The first link arm has the first rotary coupling point inside a dash panel provided at a front portion of a vehicle interior.

A vehicle door device includes a first link mechanism formed of first and second link arms having a first rotary coupling point with respect to a vehicle body and a second rotary coupling point with respect to a door of a vehicle, and a second link mechanism formed of the first and second link arms provided independently of the first and second link arms forming the first link mechanism. First and second doors respectively supported by the first and second link mechanisms open and close independently in different directions based on operations of the first and second link mechanisms. At least one of the first and second link arms forming the first link mechanism and the first and second link arms forming the second link mechanism is provided with a coupling length variable mechanism that allows a coupling length between the first and second rotary coupling points to vary.

In an opening control device that controls the opening of an access panel door, a movable member of a detecting portion, which is pushed in by a main door that is in a closed state, is brought into direct abutment with a connection lever to move the connection lever, wherein the connection lever connects a drive lever, which is linked to operate with an opening operation of the door, and a driven lever, which releases the locking by locking portions, wherein the connection lever has a displacement area which includes a connecting position and in which maintains the connection of the drive lever with the driven lever, the connection lever is moved toward a disconnecting position within the displacement area when the movable member staying in a protruding position and is moved to the disconnecting position as the movable member is pushed into the pushed-in position.

A vehicle door structure includes two doors, a weatherstrip, a moving device and a control device. The two doors are disposed adjacently at a vehicle side portion with no pillar therebetween. The weatherstrip is provided at one of the doors and is disposed to change a distance between the weatherstrip and the other door. The moving device moves the weatherstrip in a direction of putting the weatherstrip into contact with and a direction of separating the weatherstrip from the other door. When it is determined that the two doors are closed and neither is opening or closing, the control device controls movement of the moving device to put the weatherstrip into contact with the other door. When a single door is closed and the counterpart door is opening or closing, the control device controls movement of the moving device in the direction of separating the weatherstrip from the other door.

The present invention provides a vehicle side portion structure including: front and rear side doors provided at a side portion of a vehicle that does not have a center pillar; a lock member provided at at least one side door among the front and rear side doors, the lock member being disposed at a vehicle vertical direction lower portion of the one side door on another side door side thereof and, when the one side door is closed, engaging with the other side door or the vehicle body to thereby lock the one side door; and a reinforcement member provided inside the one side door at the vehicle vertical direction lower portion thereof, with at least part of the reinforcement member being disposed on an upper side of the lock member so that the lock member is surrounded by the reinforcement member and a peripheral edge portion of the one side door as seen in a vehicle side view.

A side vehicle-body structure of a vehicle that suppresses displacement of a front wall portion of a center pillar to a vehicle-width-direction inner side with respect to a rear wall portion of the center pillar due to a side collision load. The side vehicle-body structure of the vehicle in which the center pillar does not exist on a body side includes a front door, and a rear door having a length in a front-rear direction shorter than a length of the front door in the front-rear direction. The rear door has a center pillar on a door side in a front portion, and a gusset member protruding from a rear wall portion of the center pillar to a door outer panel side with respect to an outer wall portion of the center pillar and having a receiving surface portion for a side collision load along the door outer panel.

A vehicle door hinge structure includes a body bracket, a hinge arm, a door bracket and a check structure. A first end of the hinge arm is attached to the body bracket for pivoting movement about a first pivot axis. The door bracket is attached to the second end of the hinge arm for pivoting movement about a second pivot axis. A clip member of the check structure has a main body, a clip portion and a retention portion. The main body of the clip member extends through a clip aperture of the hinge arm. The bracket pin is fixedly attached to the door bracket at a location spaced apart from the second pivot axis such that with the clip portion of the clip member engaged with the bracket pin, the door bracket is retained in a fixed position.
