In a through anchor, it enables a piece to be moved to an attachment position of the piece in a metal core by moving the piece toward a vehicle front lower side in a state in which a lower end portion of a guide portion of a guide groove of the piece is abutted with a guide projection formed at a metal core lower portion of the metal core.

Anchor for seatbelt device

In a through anchor, a thinned portion is formed at a metal core lower portion of a metal core. This thereby enables an increase in body size of the through anchor to be prevented or suppressed even when a mold portion is made thick at the portion of the metal core where the thinned portion is formed.

A seatbelt device is provided with a webbing and a bag body. The webbing is applied to the body of a vehicle occupant. The bag body includes a first layer at a webbing side and a second layer at an opposite side from the webbing, with the first layer disposed therebetween. The bag body is provided along a length direction of the webbing, fixed to one side of a thickness direction of the webbing and supported by the webbing, and disposed between the webbing and the body of the vehicle occupant in a state in which the webbing is applied to the body of the vehicle occupant. The bag body is inflated by fluid being supplied thereinside. A joined portion at which the first layer and second layer are locally joined together is formed in the bag body. The inflation of the bag body is controlled by the joined portion.

Seatbelt device

A seatbelt device comprises a webbing, a bag body and an anchor member. The webbing is applied to the body of a vehicle occupant sitting on a seat. The bag body is provided along a length direction of the webbing, and the bag body is disposed at one side of the webbing and can be inflated by pressure of a fluid supplied from a length direction one side of the bag body. A deployment portion through which the fluid can pass is provided in the bag body, being disposed at width direction outer sides and a thickness direction another side of the webbing. An insertion hole is formed in the anchor member, through which the webbing and the bag body are inserted. The webbing is folded at the thickness direction one side when applied to the body of the sitting vehicle occupant, and the deployment portion of the bag body is disposed in the insertion hole.

Seat belt device

In a through anchor, a side face on a piece side of a groove portion is configured by a piece side inclined face, with the piece side inclined face being inclined in a direction such that an angle formed between the piece side inclined face and a slide face of the piece is an obtuse angle. During molding of a molded portion, an apex portion of a rib of a mold is disposed on or abuts the piece side inclined face of the piece. Movement of the piece in a length direction thereof is accordingly suppressed by the rib of the mold. The molded portion can accordingly be molded with the piece in a well-positioned state by injecting a resin material for the molded portion into the mold in this state.

Through anchor

When an attempt is made to insert a fitting-shaft section into a fitting-hole section where phases of the fitting-shaft section of a spring-screw and the fitting-hole section of an adapter about a central-axis line of a spool-body are not matched, shaft-section-side inclined-surfaces formed at shaft-section-side protrusions abut to hole-section-side inclined-surfaces formed at hole-section-side protrusions, so the shaft-section-side inclined-surfaces press the hole-section-side inclined-surfaces in such a direction inclined in a pull-out direction to a projecting-direction of a shaft-section body from a flange section. The adapter upon receiving a pressing force generated by this pressing at the hole-section-side inclined-surfaces rotates in the pull-out direction, thereby aligning phases of the fitting-hole section and the fitting-shaft section about the central-axis line such that each shaft-section-side protrusion inserts into a gap between the hole-section-side protrusions adjacent to each other, and the fitting-shaft section fits into the fitting-hole section.
