Claim 0:
1. A vehicle seatbelt device comprising:
a seatbelt that restrains a part of a body of an occupant in a host vehicle;
a tension adjustment mechanism that is able to adjust a tension of the seatbelt;
a recognizer that recognizes a situation in a vicinity of the host vehicle;
an index value deriver that derives an index value indicating an overlapping degree between a predicted traveling trajectory of another vehicle which is recognized by the recognizer and approaches the host vehicle and a predicted traveling trajectory of the host vehicle; and
a tension controller that controls an operation timing of the tension adjustment mechanism on a basis of the index value derived by the index value deriver and a degree of approach of the another vehicle with respect to the host vehicle,
wherein when the index value is equal to or greater than a threshold value, the tension controller determines whether or not a direction indicator of the another vehicle approaching the host vehicle is operating, and
wherein when the tension controller determines that the direction indicator is operating, the tension controller delays the operation timing of the tension adjustment mechanism compared to when the direction indicator is not operating.
