[0009]

【Example】

An embodiment of the present invention will be described below with reference to FIGS. 1 to 4. The automobile front seat 10 shown in FIG. 1 includes a seat portion 11 and a backrest 12. Configured with the necessary features. The seat portion 11 has a cushion height mechanism 13 having a well-known structure. Therefore, within a certain stroke range, the vertical direction relative to the backrest 12 It can be moved and fixed at a desired height. The backrest 12 is The reclining mechanism 15 allows adjustment of the inclination angle in the front and back direction. Ru.

0010 The backrest 12 includes a seatback frame (not shown) and, for example, urethane foam. The structure includes a pad 20 using a foam or the like, and a skin material 21 covering the outside of the pad 20. has been completed. As shown in FIG. 2, the sewing part 22 on the lower end side of the skin material 21 is sewn along the width direction of the backrest 12 at the bottom 23 of the backrest 12. It is being

[0011] An extension of the lower end of the skin material 21 extending downward near the rear of the sewn portion 22 A section 25 is provided. This extension 25 provides a visual field for a passenger seated in the rear seat. It is sufficient as long as it can be hidden so that the sewn part 22 does not get into the The width in the vertical direction may be relatively short.

0012 The bottom part 23 of the backrest has an elastic restoring force near the sewn part 22. A gap closing member 30 made of a flexible material is provided. Gap closing in this example The member 30 includes a band-shaped base material 31 made of soft polyvinyl chloride as an example of the material. , is rolled into a tube shape, and at the rolled butt end 32, the backrest The cover 12 is sewn to the skin material 21 of the cover 12. This gap closing member 30 is a backrest It is provided along the width direction of the backrest 12 over almost the entire width of the backrest 12. death In this gap closing member 30, the seat portion 11 is lowered by the cushion height mechanism 13. When it is lowered to its full stroke limit, it touches the rear end portion 11a of the seat portion 11. The dimensions are such that it can be

[0013] The front seat 10 equipped with the gap closing member 30 configured as described above has a cushion height. When the seat part 11 is raised by the lifting mechanism 13, as shown in FIG. Since the material 30 is easily deformed by being pushed in the direction of compression, the upward stroke of the seat portion 11 is energy is absorbed. The cushion height mechanism 13 prevents the seat 11 from being lowered. When the gap closing member 30 is lowered due to its own elastic restoring force, the gap closing member 30 is lowered. Since the lower end of the gap closing member 30 reaches the rear end portion 11a of the seat portion 11, It is possible to avoid creating a gap between the seat portion 11 and the backrest 12.

In this example, a strip-shaped base material 31 made of the same flexible material as in the above-mentioned embodiment is used, with a cross section of U to J. The bent ends 41 and 42 are bent to form a shape, and the bent ends 41 and 42 are attached to the skin material of the backrest 12. It is sewn on 21. Also in this embodiment, the cushion height mechanism 13 When the seat portion 11 is raised by , the gap closing member 40 is compressed and crushed. Since the seat part 11 is deformed in this direction, it does not become an obstacle when the seat part 11 is raised.

[0015] When the seat part 11 is lowered, the gap closing member 40 is moved under the seat part 11 due to its shape restoring force. By elastically extending the end downward, the lower end of the gap closing member 40 is brought into contact with the seat portion 11. Because of this, a gap is created between the rear end portion 11a of the seat portion 11 and the backrest 12. is avoided.

[0016] By providing the gap closing members 30 and 40 described above, the seat portion 11 and the backrest Objects may fall between the 12 and the lower back of the seated person may become cold due to the flow of air. The problem will be resolved. Moreover, these gap closing members 30, 40 are not visible from the outside. Since it is sewn to the bottom part 23 of the stake backrest 12, It does not come into the passenger's field of vision and does not impair the appearance of the seat 10. Also, Even if the backrest 12 is tilted down by the crimp mechanism 15, the gap closing members 30, 4 0 can perform the predetermined functions described above.

[0017] Note that, like the gap closing member 50 shown in FIG. 6, it is made of a flexible material such as cloth. The band-shaped base material 52 is rolled into a tube shape or a cross section of U or J shape, and the inside of this base material 52 is Built-in flexible filling 53 with shape restoring force, such as soft urethane foam, etc. Even if this is done, the intended purpose of the present invention can be achieved.
