摘要: A buckle device includes: a buckle body to which a tongue portion mounted on a three-point seat belt is to be connected; a connecting member that is flexible and that has a first longitudinal end portion connected to the buckle body; and a force limiter mechanism including a take-up shaft around which a second longitudinal end portion of the connecting member is wound, the take-up shaft being supported below the buckle body in a vertical direction of a vehicle so as to be rotatable relative to a vehicle seat or a vehicle body, and an energy absorbing member that is deformed by rotation of the take-up shaft.

摘要: In a buckle device, when a belt starts to be allowed to be drawn, a fracture portion is deformed by a side surface of a connection hole of a spool, so that the fracture portion allows a rotation of the spool and allows drawing of the belt. Then, the fracture portion is fractured by the side surface of the connection hole. Therefore, a drawing allowance load of the belt when the belt starts to be allowed to be drawn can be increased.

摘要: A seat belt device includes a buckle provided on a side portion of a seat for a vehicle, and configured such that a tongue plate is inserted into the buckle; a buckle force limiter mechanism connected to the buckle via a connecting member having an elongate shape, the buckle force limiter mechanism being configured to allow the buckle to move in a pulling direction when a tensile load equal to or larger than a predetermined tensile load is applied to the buckle; and a case covering the connecting member from an inner side in a seat width direction, the case having a corner at an upper end portion of the case, the corner facing the connecting member, and the corner having an arc shape.

摘要: In the buckle device, when or after torsional deformation of the torsion shaft has started and allowance of the drawing-out of the belt has started, the breaking portion of the shear plate is started to be deformed by the coupling hole side surface of the spool, whereby the breaking portion allows the rotation of the spool and allows the drawing-out of the belt. Therefore, the allowable drawing-out load of the belt can be made the sum of the load for torsionally deforming the torsion shaft and the load for deforming the breaking portion, and can be increased.
