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 member which is one of a seat cushion, a seatback, a headrest and an armrest, the seat structure member including:

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,

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

wherein 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.

2. The vehicle seat according to claim 1,

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

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

3. The vehicle seat according to claim 1,

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

4. The vehicle seat according to claim 1,

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

5. The vehicle seat according to claim 4,

wherein a width between adjacent protrusions ranges from 10 mm to 20 mm.
