Vehicle seat
A seat back pad 70 has a groove 73 for tucking a skin material therein, formed at borders between a central portion 71 and side portions 72 . A hole (slot hole 74 ) is formed in a bottom of the groove 73 along the groove 73 . A tuck-in wire 76 for tucking the skin material in includes a plurality of tuck-in portions 76 A provided along the groove 73 , and a connecting portion (detour portion 76 B) detouring around the hole and connecting the tuck-in portions 76 A. With this configuration, when an upper body of an occupant P subsides into a seat back S 2 in a rear-end collision of a vehicle, the central portion 71 , defined by the groove 73 as a border, is easily and sufficiently moved rearward relative to the left and right side portions 72 . Furthermore, the tuck-in wire 76 is not exposed through the hole, and thus adhesion between the seat back pad 70 and the tuck-in wire 76 can be improved.
1. A vehicle seat comprising:
a seat cushion;
a seat back;
a headrest; and
a skin material with which the seat cushion, the seat back and the head rest are covered,
wherein the seat back comprises:
a seat back frame including left and right side frames;
a pressure-receiving member;
a connecting member via which the pressure-receiving member is connected to the left and right side frames in a manner that renders the pressure-receiving member rearwardly movable; and
a seat back pad with which at least a front surface of the pressure-receiving member and the seat back frame are covered,
wherein a rearward motion load received from an upper body of an occupant seated on the seat cushion and acting on the seat back causes the pressure-receiving member to move rearward to cause the upper body of the occupant to subside into the seat back,
wherein the side frames include pad shape retainer portions each shaped like a plate jutting frontward to retain shapes of side portions of the seat back pad, and pipe portions protruding upward beyond the pad shape retainer portions,
wherein the seat back further comprises a plate-like bracket fixed to a pipe portion of one of the side frames,
wherein the bracket includes a first portion contoured to fit an outer peripheral surface of the pipe portion and fixed to the pipe portion, and a second portion extending from the first portion, an airbag device being attached to the second portion, and
wherein the first portion is located at a laterally inner side relative to a mount surface of the second portion to which the airbag device is attached.
2. The vehicle seat according to claim 1 , wherein the airbag device is disposed along the mount surface and a side surface of one of the pad shape retainer portions.
3. The vehicle seat according to claim 1 , wherein the mount surface is located frontward of the pipe portion.
4. The vehicle seat according to claim 1 , wherein the bracket is fixed to a laterally inner side portion of the outer peripheral surface of the pipe portion.
5. The vehicle seat according to claim 1 , wherein the bracket extends from an end of the mount surface that is adjacent to the pipe portion, laterally inwardly along the outer peripheral surface of the pipe portion.
6. The vehicle seat according to claim 5 , wherein the first portion includes flanges bending from an upper end and a lower end thereof.
7. The vehicle seat according to claim 1 , wherein a front end of the airbag device is located frontward of a front end of the bracket.
8. The vehicle seat according to claim 1 , wherein the bracket includes a portion extending laterally inwardly from a front end of the mount surface.
