A backrest frame is provided with a cushion plate of one substantially square plate form positioned behind the waist from the upper part of the back of a vehicle seat occupant, movably back and forth by way of a plurality of upper and lower parallel seat springs, one end of either one of a pair of right and left seat springs of the plurality of upper and lower parallel seat springs is connected to a pair of lower link mechanisms provided rotatably on the backrest frame, and a rear end collision sensor is formed by the cushion plate between the seat springs for moving a headrest forward, and a coupling part of the other end of the seat spring is directly attached to the lower link mechanism.

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 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.

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

Vehicle seat and method of assembling 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.
