Abstract

A vehicle seat including: a seat pad capable of elastically supporting an occupant, the seat pad having a seating portion that allows the occupant to seat on a front surface thereof, and the seating portion is divided in a seat width direction into a first region, a second region, and a central region formed between the first and the second region, the first region and the second region being capable of being concave-deformed toward a back surface of the seat pad opposite to the front surface when pressed by the occupant in a seating state, and in a free state where the seating portion is not pressed, a central region part in the central region arranged between the first and the second region that are to be concave-deformed has a shape concaved toward the back surface of the seat pad as compared to the first and the second region.

First claim

What is claimed is:

1 . A vehicle seat comprising:
a seat pad capable of elastically supporting an occupant, the seat pad having a seating portion that allows the occupant to seat on a front surface thereof, wherein the seating portion is divided in a seat width direction into a first region, a second region, and a central region formed between the first region and the second region, both the first region and the second region being capable of being concave-deformed toward a back surface of the seat pad opposite to the front surface when pressed by the occupant in a seating state, and wherein in a free state where the seating portion is not pressed, a central region part in the central region arranged between the first region and the second region that are to be concave-deformed has a shape concaved toward the back surface of the seat pad as compared to the first region and the second region.

2 . The vehicle seat according to claim 1 ,
wherein in a state where the seat pad is pressed by the occupant, assuming a virtual line that extends in the seat width direction and connects positions of the first region and the second region where each of the positions of the first region and the second region is concaved the most in each of the first region and the second region, the central region part is located at a position the same as the virtual line or closer to the back surface of the seat pad than the virtual line.

3 . The vehicle seat according to claim 1 ,
wherein in a state where the seat pad is pressed by the occupant, the central region part is located at a closest position of the seating portion to the back surface of the seat pad.

4 . The vehicle seat according to claim 1 ,
wherein the first region, the second region, and the central region are divided and partitioned by a groove-shaped divisional portion or a notch-shaped divisional portion provided on the front surface of the seat pad.

5 . The vehicle seat according to claim 1 , comprising:
a seat cover covering the seat pad, wherein a part of the seat cover is locked and held in a manner retracted into a hooking groove extending in the seat width direction on the front surface of the seat pad, wherein the hooking groove is provided adjacent to at least one of a front side of the first region, the second region, and the central region, and a rear side of the first region, the second region, and the central region, and wherein an end portion of the central region on the hooking groove side is raised closer to the seat cover side than the central region part.

6 . The vehicle seat according to claim 5 ,
wherein the hooking groove is provided adjacent to both the front side and the rear side of the first region, the second region, and the central region.

7 . The vehicle seat according to claim 5 ,
wherein a surface of the end portion of the central region on the hooking groove side is inclined or curved.

8 . The vehicle seat according to claim 1 , comprising:
a seat cover covering the seat pad; and an accessory disposed between the seat cover and the seat pad, wherein at least a part of the accessory is disposed on a surface of the central region part.
