Further, the insect repellent 22 is easily taken out from the notch 24 through the opening 24A to the outside of the seat back 14.

Therefore, even if the effectiveness of the insect repellent 22 decreases with the passage of time, the insect repellent 22 can be taken out from the opening 24A of the notch 24 and easily replaced with a new insect repellent. Further, when the insect repellent 22 having a function of displaying a replacement sign is stored, the insect repellent 22 can be taken out from the notch 24 and the replacement sign can be checked frequently, and the insect repellent 22 is replaced at an appropriate replacement time. can do.

Further, the insect repellent 22 can be easily taken out and replaced with another storage member. For example, the dehumidifying agent is stored in the notch 24 during the rainy season when the humidity inside the vehicle is high, and the insect repellent 22 is replaced at other times. You can also do it.

Further, according to the vehicle seat 10 according to the present embodiment, the front end portion 34A of the seat back pad 18 is elastically deformed when the insect repellent 22 is inserted into the cut portion 24 or taken out from the cut portion 24. Then, the opening 24A including the non-sutured portion 32 is temporarily opened. On the other hand, when nothing is stored in the notch 24 or when the insect repellent 22 is contained in the notch 24, the opening 24A is closed by the restoring force of the seat back pad 18. That is, the opening 24A is closed except when the insect repellent 22 is taken in and out, and the insect repellent 22 is not visible from the outside.

In particular, according to the vehicle seat 10 according to the present embodiment, the cut portion 24 is provided at a position corresponding to the boundary portion between the first skin material 28 and the second skin material 30. The front end portion 34A of the pad cut 34 is covered with the lower end portion 28A of the first skin material 28 and the upper end portion 30A of the second skin material 30 bent rearward. Therefore, in the state where the opening 24A is closed, the lower end portion 28A of the first skin material 28 and the upper end portion 30A of the second skin material 30 are overlapped with each other in the non-sewn portion 32 as well as the stitched portion. Therefore, even in the non-sewn portion 32, the seat back pad 18 does not need to be visually recognized from the outside. Further, since it is possible to visually recognize that the sutured portion is integrally formed from one end portion to the other end portion of the skin 26 in the left-right direction, the cut portion 24 can be provided on the seat back 14 inconspicuously. .. As a result, the design of the seat back 14 and thus the vehicle seat 10 can be maintained satisfactorily.

Therefore, the insect repellent 22 can be stored in the seat back 14 inconspicuously. As a result, it is possible to prevent pests from being generated on the seat back 14 while maintaining the design of the vehicle seat 10.

Further, according to the vehicle seat 10 according to the present embodiment, the notch portion 24 is configured with the seat back pad 18 exposed except for the front end portion 34A. Therefore, the effect of the insect repellent 22 is directly exerted on the seat back pad 18, and an excellent insect repellent effect can be obtained.

Furthermore, according to the vehicle seat 10 according to the present embodiment, the insect repellent 22 is housed inside the vehicle seat 10. Therefore, even when the insect repellent 22 is stored on the front side of the seat back 14 as in the present embodiment, the occupant does not feel a foreign body sensation, and it is possible to prevent the comfort from being impaired.

In the present embodiment, the vehicle seat 10 in which one notch portion 24 is provided in the front center portion of the seat back 14 has been described, but the present invention is not limited to this. The number of notches may be plural, and may be provided in the seat cushion 12 or the headrest 16. For example, as in the modified example shown in FIG. 3, a notch 27 may be provided on the side surface of the seat back 14. Similarly, notches 29, 31, and 33 may be provided on the upper surface, the front surface, and the side surface of the seat cushion 12, respectively. Further, notches 35, 37 and 39 may be provided on the upper surface, the front surface and the side surface of the headrest 16, respectively.

(Second Embodiment)
Next, the vehicle seat 40 according to the second embodiment will be described with reference to FIG. The same components as those in the first embodiment are designated by the same reference numerals, and the description thereof will be omitted as appropriate.

The vehicle seat 40 is provided with a pocket 44 as a storage portion on the left side surface of the seat back 42. The pocket 44 is formed in a substantially rectangular shape in a side view, and includes an opening 44A opened upward.

The pocket 44 is made of a breathable cloth material 48, and is formed in a bag shape by being sewn on a cloth third skin material 46 covering the left side surface of the seat back 42. The cloth material 48 is formed in a substantially rectangular shape, and three sides excluding one upper side are sewn to the third skin material 46.

Further, a flap 50 is provided on the upper side of the pocket 44 so as to cover the opening 44A. The flap 50 is made of the same cloth as the third skin material 46, and is formed in a substantially rectangular shape that is longer in the front-rear direction than the cloth material 48 in a side view. In the flap 50, one upper side is sewn to the third skin material 46, and one lower side is located below the opening 44A of the pocket 44.

Here, the deodorant 52 as a storage member is stored in the pocket 44. It is assumed that the deodorant 52 contains, for example, a jelly having a deodorizing effect in a thin rectangular parallelepiped case in which a large number of slits are formed. Not limited to this, a deodorant using another material having a deodorizing effect such as activated carbon may be stored.

(Action and effect of this embodiment)
Next, the operation and effect of this embodiment will be described. The description of the same action and effect as in the first embodiment will be omitted.

According to the vehicle seat 40 according to the present embodiment, a general-purpose seat back pad can be used as compared with the case where the notch portion 24 is formed in the seat back 14 as in the first embodiment, so that the seat back can be used. The design change of the pad 18 becomes unnecessary, and the manufacturing cost does not increase.

Further, according to the vehicle seat 40 according to the present embodiment, since the cloth material 48 has breathability, the deodorant 52 continuously comes into contact with the air in the vehicle interior. Therefore, the deodorant 52 can be stored in the seat back 42 without impairing the effect of the deodorant 52.

Further, according to the vehicle seat 40 according to the present embodiment, since the opening 44A is covered with the flap 50, the deodorant 52 is not visible from the outside. Therefore, the deodorizing effect of the deodorant 52 can be obtained while maintaining the design of the vehicle seat 40.

Further, for example, the shape of the storage member may be a sheet shape.

Further, in the first embodiment, the notch portion 24 has been described as being configured in a state where the seat back pad 18 is exposed except for the front end portion 34A, but the present invention is not limited to this, and the notch portion 24 is provided inside the notch portion 24. A cloth material different from that of the epidermis 26 may be provided and sutured with the epidermis 26. In this case, the design of the cut portion 24 when the opening 24A is opened can be improved. Further, since the insect repellent 22 is unlikely to be caught on the lower end portion 28A of the first skin material 28 and the upper end portion 30A of the second skin material 30 in the non-sewn portion 32, the insect repellent 22 can be smoothly taken out from the cut portion 24. Further, it is possible to prevent the pad from being damaged when the insect repellent 22 is replaced.

Further, in the first embodiment, the non-sewn portion 32 is provided at the boundary between the first skin material 28 and the second skin material 30, and the cut portion 24 is provided along the non-sewn portion 32. Although explained as a thing, it is not limited to this. For example, as shown in FIG. 3, in one skin material provided on the left side surface of the seat cushion 12, a cut portion may be formed in the central portion thereof.

Further, in the second embodiment, the vehicle seat 40 in which the pocket 44 is provided on the left side surface of the seat back 42 has been described, but the present invention is not limited to this.
