Abstract

A vehicle seat including: a seat component such as a seat cushion and a seat back, the seat component including, a cushioning material constituting an outer shape of the vehicle seat, a through-hole penetrating the cushioning material in a thickness direction thereof, and a skin material configured to cover the cushioning material, wherein a reinforcing wire is embedded into the cushioning material at both sides of the through-hole, respectively.

Claims

1. A vehicle seat comprising:

a seat component having a central main portion and side portions provided at opposing outer sides of the central main portion, the seat component including;

a cushioning material constituting an outer shape of the vehicle seat;

a through-hole penetrating the cushioning material in a thickness direction thereof between the side portion and the outer side of the central main portion; and

a skin material configured to cover the cushioning material,

wherein a reinforcing wire is embedded into the cushioning material at both sides of the through-hole, respectively, along the side portion and the outer side of the central main portion.

2. The vehicle seat according to claim 1,

wherein the seat component includes a fixing wire which is provided in a groove portion of the cushioning material and a suspending wire which is provided to the skin material and configured to be arranged so as to be opposed to the fixing wire,

wherein a portion of the skin material is attached to the cushioning material in a suspending form by a connection between the fixing wire and the suspending wire, and

wherein the reinforcing wire is configured by at least a portion of the fixing wire.

3. A vehicle seat comprising:

a seat component having a central main portion and side portions provided opposing outer sides of the central main portion, the seat component including;

a cushioning material constituting an outer shape of the vehicle seat;

a through-hole penetrating the cushioning material in a thickness direction thereof between the side portion and the outer side of the central main portion; and

a skin material configured to cover the cushioning material,

wherein a first reinforcing wire is embedded into the cushioning material at a first side of the through-hole, and a second reinforcing wire is embedded into the cushioning material at a second side of the through hole opposite to the first side along the side portion and the outer side of the central main portion.

4. The vehicle seat according to claim 3,

wherein the first reinforcing wire and the second reinforcing wire are opposed to each other with the through-hole therebetween.

5. The vehicle seat according to claim 3,

wherein the first reinforcing wire and the second reinforcing wire are arranged parallel to the through-hole.

6. The vehicle seat according to claim 3,

wherein the second reinforcing wire is provided at an outer side with respect to the first reinforcing wire, and

wherein the second reinforcing wire includes a bent portion that avoids the through-hole.

7. The vehicle seat according to claim 3,

wherein the first reinforcing wire and the second reinforcing wire are positioned at the same position in the thickness direction of the cushioning material.
