Abstract:
1. A door opening and closing apparatus for a vehicle, comprising: a first hinge base adapted to be fixedly mounted to a vehicle body; a second hinge base adapted to be fixedly mounted to a vehicle door; a four-link hinge including a first hinge arm and a second hinge arm for connecting the first hinge base with the second hinge base in a manner so that the first hinge base and the second hinge base pivot relative to each other, the four-link hinge supporting the vehicle door between a fully open position and a fully closed position; a fully open position locking mechanism adapted to be fixedly mounted on the vehicle door for locking the vehicle door relative to the vehicle body at the fully open position; and an unlocking mechanism adapted to be fixedly mounted on the fully open position locking mechanism for releasing a locked condition of the vehicle door at the fully open position achieved by means of the fully open position locking mechanism, wherein the fully open position locking mechanism includes a striker provided at an end portion of the second hinge arm, a latch rotatably supported by the second hinge base for selectively engaging with and disengaging from the striker so that the latch engages with the striker during the vehicle door being at the fully open position, and a pawl rotatably supported by the second hinge base for selectively engaging with and disengaging from the latch in a manner so that an engagement of the pawl with the latch restricts the latch from rotating in a direction of releasing an engagement thereof with the striker, and wherein the latch includes a notch formed thereon and the striker includes a flattened sphere-like portion formed thereon to be fitted into the notch so that the striker and the latch engage with each other by allowing the flattened sphere-like portion to be fitted into the notch.
