A seat back padhas a groovefor tucking a skin material therein, formed at borders between a central portionand side portions. A hole (slot hole) is formed in a bottom of the groovealong the groove. A tuck-in wirefor tucking the skin material in includes a plurality of tuck-in portionsA provided along the groove, and a connecting portion (detour portionB) detouring around the hole and connecting the tuck-in portionsA. With this configuration, when an upper body of an occupant P subsides into a seat back Sin a rear-end collision of a vehicle, the central portion, defined by the grooveas a border, is easily and sufficiently moved rearward relative to the left and right side portions. Furthermore, the tuck-in wireis not exposed through the hole, and thus adhesion between the seat back padand the tuck-in wirecan be improved.

A vehicle seat comprises a seat bottom frameas a frame of a seat bottom allowing an occupant to sit thereon, and a seat back framesupported by the seat bottom frame. The seat back frameincludes right and left side frames SF laterally spaced apart from each other, and a lower connecting memberdisposed and extending between lower portions of the right and left side frames SF and configured to connect the right and left side frames SF, and the lower connecting memberincludes a rear wall portion connected to and supported by the side frames SF, and a front wall portiondisposed frontward of the rear wall portion and extending downward from an upper end of the rear wall portion, and a front surfaceA of the front wall portionhas an upper portion and a lower portion which is located frontward of the upper portion.

Provided is a vehicle seat by which an impact of rear end collision is reduced and of which peripheral structure of a side frame is simplified. A vehicle seat includes: a seat back frame which includes side portions positioned at the sides thereof, a pressure receiving member which is jointed to the seat back frame through joint members and supports an occupant, and an impact reduction member which is disposed on at least one of the side portions to engage with the joint member and to move by a predetermined amount of impact load applied to the pressure receiving member so that the pressure receiving member is caused to move rearward; in which the side portion includes a convex portion protruding in the movement range of the impact reduction member, and the impact reduction member abuts against the convex portion so that the movement of the impact reduction member is prevented.

A vehicle seat has a mechanism for moving a headrest upon rear-end collision, comprising: a pressure receiving member for receiving a load of a rearward movement of an occupant; a transmitting element for transmitting the load received by the pressure receiving member to a headrest side; right and left headrest supporting members for supporting right and left pillars of the headrest; and a biasing member that biases the headrest; wherein the biasing member is disposed between the right and left pillars.

A vehicle seat has a mechanism for moving a headrest upon a rear-end collision, wherein the vehicle seat comprises a plate-like support body for receiving a load of a rearward movement of an occupant; a link mechanism for transmitting the load received by the plate-like support body to the headrest side, and comprising a lower link, an upper link, and a connecting link; and a load retaining member for blocking the load received by the plate-like support body from being transmitted to the link mechanism, until the load reaches a predetermined level; wherein the load retaining member is held by one of the lower link and the connecting link, and is configured to urge the lower link and the connecting link in a separating direction.
