Abstract: A seat slider device may include an upper rail; a lower rail slidably holding the upper rail; a bolt fixing the lower rail to a vehicle body; a washer through which the bolt passes; and a retainer retaining the bolt to the lower rail before the lower rail is fixed to the vehicle body with the bolt. The lower rail may include a bottom plate; a pair of outer vertical plates extending upward respectively from ends of the bottom plate; a pair of upper plates horizontally extending respectively from upper ends of the outer vertical plates to an inside of the lower rail; and a pair of inner vertical plates extending downward respectively from inner ends of the upper plates. The retainer may be arranged in the lower rail and configured to retain the bolt with the bolt through the washer and the through hole.

Abstract: In an anchor (10), an insertion hole (42) is formed piercing through an anchor main body (36), and a belt is inserted through the insertion hole (42). A projection (44) is formed at the anchor main body (36) around the entire periphery of the insertion hole (42), and the projection (44) configures an outer peripheral face of the insertion hole (42). The projection (44) projects out toward the radial direction outer side of the insertion hole (42). The surface area of a portion configured by the projection (44) at the outer peripheral face of the insertion hole (42) can accordingly be increased, and the contact surface area of the belt with the outer peripheral face of the insertion hole (42) can be increased, even when the plate thickness dimension of the anchor main body (36) is reduced. This thereby enables the plate thickness dimension of the anchor main body (36) to be reduced.

Abstract: In a through anchor (10), a guide piece (24) is molded in an area around a through hole (16) in an anchor plate (12), webbing (30) is inserted through an insertion hole (26) in the guide piece (24) in such a way that the webbing is movable along a lengthwise direction, and the webbing (30) is slidably supported on a sliding surface (28) of the guide piece (24). Here, the guide piece (24) is placed only on the whole circumference of the through hole (16) in the anchor plate (12) and allows an entire outer peripheral end surface (12C) of the anchor plate (12) to be exposed. For this reason, the use amount of molding resin of the guide piece (24), which is molded from a relatively high-grade resin, and the cost of the through anchor (10) can be reduced.

Abstract: In a through anchor (10), when an occupant is restrained by webbing (30) in a vehicle emergency, the webbing (30) is moved to the vehicle front side in an insertion hole (22) of a guide piece (18) by movement of the occupant due to inertia, and a vehicle front side end face of the webbing (30) contacts a peripheral face of the insertion hole (22) at high load. A gap is formed between the guide piece (18) and an anchor plate (12). The guide piece (18) is accordingly moved to the vehicle front side with respect to the anchor plate (12) by the webbing (30), thereby enabling occurrence of skewing of the webbing (30) toward the vehicle front side in the insertion hole (20) to be suppressed.

Abstract: A through anchor (10), in which, when an occupant is restrained by a webbing (28) in a vehicle emergency, the webbing (28) is moved to the vehicle front side of an insertion hole (20) of a guide piece (18) due to movement of the occupant under inertia, and a vehicle front side end face of the webbing (28) contacts a displacement wall (26) of the guide piece (18) at high load. Rigidity of the displacement wall (26) of the guide piece (18) is reduced due to a displacement hole (24). The displacement wall (26) is accordingly deformed and displaced to the vehicle front side by the webbing (28), enabling occurrence of skewing of the webbing (28) toward the vehicle front side in the insertion hole (20) to be suppressed.

Abstract: In a tongue used in a seat belt system, a tongue main body 25 including a belt insertion hole 23 in which to insert a seat belt 3 is provided with an insertion part 27 in a projecting manner. The insertion part 27 is capable of being inserted in a buckle in the seat belt system, and includes a lock hole 27a to which a lock piece included in the buckle is capable of being locked. A front surface of the insertion part 27 is formed into a concave and convex surface by being provided with multiple convex parts 29 or multiple concave parts. The convex parts 29 or the concave parts included in a rear surface of the tongue are formed corresponding to the convex parts 29 or the concave parts included in the front surface. A height of each convex part 29 from a reference position or a depth of each concave part from the reference position is 0.01 mm to 0.10 mm.

Abstract: A seat belt anchorage plate for a seat belt device formed with a plate shaped member (base) 2 is provided with a slot 6 into which a belt (waist belt) 13 is inserted and which has long edge parts opposed with each other. The belt 13 is folded back along the one long edge part 691 of the opposed long edge parts in the slot 6 so that the one long edge part 691 bears the tension of the belt 13. The one long edge part 691 is formed so as to expand in the direction opposite to that of the tension of the belt 13 toward a central part from both ends in its longitudinal direction.

Abstract: A seat belt hanging and holding member of the present invention is capable of reducing manufacturing cost by reducing the material cost required for a coating member while improving safety. The seat belt hanging and holding member 10 slidably hangs and holds a seat belt by folding back an intermediate part of the seat belt (waving belt) 74. The member 10 comprises a base member, 20 made of a metal plate having a slot 22 and a coating member 30 made of a synthetic resin which covers at least the periphery of the slot 22 of the base member 20 and is provided with a seat belt-inserting hole 31 on a part corresponding to the slot 22. The slot 22 is provided with an edge part 22a corresponding to at least the part on which the seat belt 74 is folded back, which is formed in a smoothly curved surface along the direction in which the seat belt 74 is folded back.
