Abstract

There is provided a vehicle seat including a seat structure member which has a frame member which configures a seat framework, a pad member which configures an outer shape of the seat and is configured to elastically support an occupant, and a sheet-like elastic fiber body which is disposed on a rear surface of the pad member. The pad member is disposed on the frame member while the elastic fiber body contacting the frame member. The elastic fiber body includes protrusions which protrude toward the frame member and recesses which are closer to the pad member than the protrusions, and the elastic fiber body is configured to come into point or line contact with the frame member by the protrusions.

Claims

1. A vehicle seat comprising a seat structure which is one of a seat cushion, a seatback, a headrest and an armrest, the seat structure including:

a frame which defines a seat framework;

a pad which defines an outer shape of the seat and is configured to elastically support an occupant; and

a sheet-like elastic fiber body which is disposed on a rear surface of the pad,

wherein the pad is disposed on the frame while the elastic fiber body contacts the frame,

wherein the elastic fiber body includes protrusions which protrude toward the frame and recesses between the protrusions, and the elastic fiber body is configured to come into point or line contact with the frame by the protrusions, and

wherein the pad is made of resin foam, and when forming material of the resin foam is foamed, the pad is formed to include protrusions and recesses between the protrusions, the forming material is impregnated to the protrusions of the elastic fiber body and cured, and the protrusions and the recesses of the elastic fiber body are formed to correspond to the protrusions and the recesses of the pad.

2. The vehicle seat according to claim 1,

wherein the elastic fiber body is integrated with the pad during foam formation of the pad, and

wherein the protrusions of the elastic fiber body and the recesses of the elastic fiber body are formed linearly along a foam direction of a forming raw material of the pad.

3. The vehicle seat according to claim 1,

wherein a thickness of the elastic fiber body at the protrusions of the elastic fiber body is same as a thickness of the elastic fiber body at the recesses of the elastic fiber body.

4. The vehicle seat according to claim 1,

wherein a height of the protrusions of the elastic fiber body ranges from 10 mm to 20 mm.

5. The vehicle seat according to claim 4,

wherein a width between adjacent protrusions of the elastic fiber body ranges from 10 mm to 20 mm.

6. The vehicle seat according to claim 1,

wherein an amount of impregnation of the forming material to the recesses of the elastic fiber body is smaller than an amount of impregnation of the forming material to the protrusions of the elastic fiber body.

7. The vehicle seat according to claim 1,

wherein the elastic fiber body contacts the frame on at least two opposing sides of the frame.
