Claims

[Scope of utility model registration request]

One of the fasteners is attached to a support plate that protrudes from the upper rail constituting the seat track, supports one side of the seat, and is slidably attached to the middle part of the seat belt. A connected first anchor member in the form of a portal; and a second anchor that extends along the seat track by penetrating the inside of the portal portion of the anchor member and is assembled to the vehicle body so that its rear end portion can rotate in the vertical direction. member, the first anchor member is connected to the second anchor member when the seat is moved in the front-rear direction.
When the first anchor member slides in the front-rear direction and a predetermined load is applied to the seat belt, the engagement pin provided at the lower end of the gate-shaped portion of the first anchor member engages the second anchor member. In an anchor mechanism for a vehicle seat belt in which both anchor members are locked together by engaging an engaging groove formed on the lower end surface of the covering resin layer, the first anchor member and the support plate are engaged with each other. An anchor mechanism for a vehicle seat belt, characterized in that the anchor mechanism is assembled via a shear pin that is sheared under a load greater than the load.
