1. A double-leaf vehicle door device comprising:
a first door leaf movable by a first drive device between a first open position and a first closed position as respective end positions, and into any intermediate positions between the first open position and the first closed position;
a second door leaf movable by a second drive device between a second open position and a second closed position as respective end positions, and into any intermediate positions between the second open position and the second closed position,
wherein a first movement of the first door leaf between the first open position and the first closed position, with respect to a second movement of the second door leaf between the second open position and the second closed position, takes place without mechanical coupling between the first door leaf and the second door leaf, and
wherein the first door leaf carries a first elastic seal, and/or the second door leaf carries a second elastic seal, configured such that the first seal and the second door leaf or the second seal and the first door leaf or the first seal and the second seal contact one another force-transmissively when the first door leaf is in the first closed position and the second door leaf is in the second closed position, or when the first door leaf is already in the first closed position and the second door leaf stands at a point shortly before assuming the second closed position, or when the second door leaf is already in the second closed position and the first door leaf stands at a point shortly before assuming the first closed position,
wherein a common locking device is provided which both locks the first door leaf in the first closed position when said door leaf is in the first closed position, and also locks the second door leaf in the second closed position when said door leaf is in the second closed position,
wherein the locking device comprises a rotatably mounted locking pawl which cooperates with a first rotatably mounted rotary latch and with a second rotatably mounted rotary latch,
wherein a pre-locking function is provided which is configured such that when the first door leaf reaches its closed position first, it is held in this closed position in contact with a first rotatably mounted rotary latch of the common locking device, preloading the locking pawl against the first rotatably mounted rotary latch at least until the second door leaf has also reached its closed position, and the locking device is furthermore configured such that only when the first door leaf and the second door leaf are in their respective closed positions does the locking device assume a lock position to lock the first door leaf and the second door leaf.
