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.

Vehicle seat

A vehicle seat of the present disclosure includes a seat cushion; a seatback; a sliding device; a first locking mechanism configured to restrict a sliding movement of a seat main body; a tip-up mechanism configured to rotationally displace the seat cushion upwardly from an occupiable position in conjunction with a frontward rotational movement of the seatback; a second locking mechanism configured to restrict a sliding movement of the seat main body when an elevation angle of the seat cushion exceeds a preset angle, and remove the restriction when the elevation angle is equal to or below a preset removal angle; and a first restrictor configured to restrict the elevation angle from being equal to or below the removal angle when the tip-up mechanism is activated.

A locking device for a vehicle seat including: a striker and a lock mechanism including: a base plate; a hook supported rotatably by a hook shaft to the base plate and capable of forming a locked state and an unlocked state; a pawl supported rotatably by a pawl shaft to the base plate; and a cam supported rotatably by the pawl shaft to the base plate, and the cam is rotationally biased by a first torsion coil spring, and the pawl is rotationally biased by a second torsion coil spring, and the coil of the second torsion coil spring has a larger diameter and a smaller length in a central axis direction of the coil than the coil of the first torsion coil spring, and one end of the first torsion coil spring is provided on a radially outer side than the coil of the second torsion coil spring.

Locking device for vehicle seat

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.

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.
