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: A vehicle seat includes a conjunction mechanism and a locking mechanism. When a seat cushion is placed at a raised position, the conjunction mechanism causes an ottoman to be placed at a stored position closer to the seating surface relative to a standby position. The locking mechanism restricts movement of the ottoman when the seat cushion is placed at a seating position. The locking mechanism includes an anchoring portion, a traction cable, and a wound portion. In response to a change being made in an amount of winding of the traction cable around the wound portion due to the seat cushion being moved, anchoring of the ottoman by the anchoring portion and canceling of the anchoring are caused.

Abstract: Provided is a vehicle seat. In the vehicle seat, a tilting member transmits a pivoting force to a back frame. An engagement member is coupled to the back frame, and allows transmission of the pivoting force to the back frame when the engagement member is in the engaged position. A recliner comprises an output gear that moves integrally with the tilting member. An amount of elastic deformation of a fold down spring increases when the back frame pivots in a rearward direction. A first anchoring member is a member that is fixed to the back frame and to which a first end of the fold down spring is anchored. A second anchoring member is a member to which a second end of the fold down spring is anchored and that moves integrally with the output gear.

Abstract: Provided is a vehicle seat capable of resisting a large load in a forward or rearward direction while reducing increase in size and weight. The vehicle seat comprises a cushion frame, a back frame, a tilting member arranged on a pivot axis of the back frame and configured to transmit to the back frame a pivoting force to pivot the back frame, an engagement member coupled to the back frame and displaceable between an engaged position in which engagement with the tilting member is made and an unengaged position in which the engagement is released, a locking member displaceable between a locking position to retain the engagement member in the engaged position and a non-locking position, and a stopper fixed to the back frame and capable of receiving, through the engagement member, an external force that acts on the engagement member located in the engaged position.
