A seat frame for a vehicle seat includes a seat cushion frame that forms a frame for a seating portion of the vehicle seat, and a height adjustment mechanism that is coupled to the seat cushion frame and a rail mechanism of the vehicle seat. The height adjustment mechanism adjusts the height of the seat cushion frame. The height adjustment mechanism includes a sector gear that rotates based on a height adjustment operation, a link that moves the height of the seat cushion frame up and down based on the rotation of the sector gear, and a restriction member that abuts against the sector gear, thereby restricting the movement of the sector gear. At least one of portions of the sector gear and the restriction member that abut against each other has a tapered shape.

Seat frame

A seat back structure for a vehicle according to one aspect of the present invention including a headrest, a seat back frame, a pad disposed in front of a surface of the seat back frame, a backrest surface of the pad, and right and left side supports each provided on either side of the backrest surface in a seat width direction, in which a right slit portion and a left slit portion are provided between the backrest surface and the right and the left side supports, respectively, each of the right slit portion and the left slit portion penetrating the pad in the thickness direction of the pad and extending in a vertical direction of the pad, and the right and the left slit portions are spaced apart from each other in the seat width direction.

Seat back structure for vehicle

A vehicle seat cushion is provided with: a cushion body that makes contact with the body of a vehicle occupant; and a plurality of spring bodies that are suspended on a seat frame so as to extend in the fore-and-aft direction of the seat. The plurality of spring bodies include inner region spring bodies that are placed underneath the hipbone of the vehicle occupant, and outer region spring bodies that are placed on the outer sides of the inner region spring bodies in the transverse direction of the seat. Moreover, if a cross-section of the seat extending in the fore-and-aft direction is viewed, then at least the inner region spring body portion that is located on the front side of the bottommost end portion of the hipbone of the vehicle occupant is seen to be positioned lower than the outer region spring bodies.

Vehicle seat cushion

A seatback device configured to elastically support a planar elastic body between left and right side frames. The seatback device includes left and right first springs and left and right second springs. The left and right first springs have axes respectively, extending in the width direction of the vehicle. The upper parts of the left and right sides of the planar elastic body body are connected to the left and right side frames through the left and right first springs. The left and right second springs have axes, respectively, extending in the front-and-rear direction of the vehicle body. The lower parts on the left and right sides of the planar elastic body are connected to the left and right side frames through the left and right second springs.

Seatback device

A vehicle seat is provided comprising a seat back frame having right and left side frames, a headrest for supporting a head of a seat occupant, and a back-and-forth movable plate member provided inside a backrest that is positioned at a rear of the seat occupant, wherein a backward movement of the plate reduces a distance between the head of the seat occupant and the headrest. The plate is attached to each side frame through a link member and a link support shaft swingably supports the link member. A bracket member that supports the link support shaft and is attached to the side frame.

Vehicle seat

A vehicle seat is provided comprising a seat back frame having right and left side frames, a headrest for supporting a head of a seat occupant, and a back-and-forth movable body provided inside a backrest that is positioned at a rear of the seat occupant, wherein a backward movement of the back-and-forth movable body forwardly moves the headrest to support the head of the seat occupant. The back-and-forth movable body is attached to each side frame through a link member and is provided with a backward protrusion protruding backward, and the backward protrusion extends laterally.

Coupling mechanism for headrest of vehicle seat

A vehicle seat of the invention has an upper movable member () supporting a headrest (), a lower movable member () provided inside a backrest, and a coupling mechanism for coupling the upper movable member and the lower movable member. The coupling mechanism includes an upper link mechanism () positioned in an upper part of a side frame () and coupled to the upper movable member, a lower link mechanism () positioned in a lower part of the side frame and coupled to the lower movable member, and a rod () extending along the side frame and coupling the upper link mechanism and the lower link mechanism. The upper link mechanism amplifies a backward moving amount of the lower movable member, and moves the headrest forward.

A vehicle seat of the invention includes: a rectangular-shaped seat back frame () having a pair of side frames (); a plurality of seat springs (A,B) disposed between the side frames; a single plate-shaped flexible cushion plate () attached to the seat springs; a seat cushion () provided on the front side of the cushion plate; link mechanisms () provided near the side frames; and a headrest () coupled to the link mechanisms (). Both ends of the seat spring (B) are coupled to the link mechanisms. When the seat spring (B) is moved rearward, the headrest is moved forward. Both sides of each of the remaining seat springs (A) are mounted to the side frames.
