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.

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 seat is disclosed for use in a vehicle. The seat includes a pivotable seat cushion, a pivotable seatback, and a pivotable headrest. A rearward portion of the seat cushion is pivotably attached to the floor of the vehicle by an anchor member. A forward portion of the seat cushion is pivotably coupled to a forward support leg that contacts the floor of the vehicle when the seat cushion is retained in a generally horizontal position. The forward support leg automatically retracts to a position proximate the seat cushion when the seat cushion is released and pivoted upwardly to a generally vertical stowed position proximate the seatback. The seatback is pivotably attached to the anchor member and may be downwardly pivoted to a generally horizontal stowed position proximate the seat cushion. The headrest may be pivotally attached to the seatback, and may be movable to a stowed position.

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.

When a pressure receiving plate provided at a seat back moves to a rear side of a vehicle body when a vehicle is collided from behind, a Bowden cable transmits movement of the pressure receiving plate to a headrest ascending mechanism as a tensile load, thereby quickly ascending a headrest to reliably hold a head of an occupant. The Bowden cable transmits only the tensile load, and hence the Bowden cable is not buckled. Reduction in weight is made possible as compared with the case using a rod for transmitting a compression load. Since the Bowden cable is light, it is not required to unreasonably place the pressure receiving plate at a position near the headrest ascending mechanism for reduction in weight, and hence the pressure receiving plate can be placed at the optimal position where a sufficient driving force is obtained at the time of collision. Thus, a headrest is ascended with favorable responsiveness upon a rear-end collision of a vehicle while using a thin transmission member with low rigidity.

Head rest device

A seat slide for a vehicle, including a lower rail fixed to a floor of the vehicle, an upper rail fixed to a seat of the vehicle, a lock plate disposed within an inner space between the lower and upper rails and secured to the lower rail, a latch lever with a pawl which is disposed within the inner space and pivotally supported by the upper rail, and a position sensor for detecting a position of the upper rail relative to the lower rail, the position sensor being mounted to the upper rail such that a sensing portion thereof is disposed within the inner space and opposed to the lock plate.

Seat slide for vehicle

A lock releasing button is provided at a slide plate including a slip joint for slidably supporting a webbing for restraining an occupant to a seat. Locking of the slide plate to a center pillar is arranged to be released when the lock releasing button is pressed upward from below. Therefore, when an airbag presses to open a connecting portion between a roof lining and a pillar garnish and deploys downward at a time of collision of a vehicle, the lock releasing button is prevented from releasing the locking by being pressed by the airbag deploying downward. This prevents the situation in which the slip joint is moved downward together with the slide plate to loosen the webbing and thus a seat belt device cannot sufficiently exhibit an occupant restraining performance.
