Claim 6:
7. A tension control method in which
a computer of a vehicle seatbelt device
recognizes a situation in a vicinity of a host vehicle,
derives an index value indicating an overlapping degree between a predicted traveling trajectory of a recognized another vehicle approaching the host vehicle and a predicted traveling trajectory of the host vehicle,
controls an operation timing of a tension adjustment mechanism which is able to adjust a tension of a seatbelt restraining a part of a body of an occupant in the host vehicle on a basis of the derived index value and a degree of approach of the another vehicle with respect to the host vehicle,
when the index value is equal to or greater than a threshold value, determines whether or not a direction indicator of the another vehicle approaching the host vehicle is operating, and
when it is determined that the direction indicator is operating, delays the operation timing of the tension adjustment mechanism compared to when the direction indicator is not operating.
