An armrest that is rotatably attached to the side portion of the seat back and can be switched to swing between a use posture and a standing storage posture,
The width of the seat cushion is set to be longer than the width of the seat back, and the side portion of the seat cushion on the armrest side protrudes below the armrest, so that the rear end portion of the armrest and the rear of the seat cushion The present invention relates to an automobile seat in which a gap is formed between end portions.

There is a bench seat type seat as an example of a seat mounted in the front part of the interior of an automobile. In the bench seat type seat, a center console is not provided between the driver seat and the passenger seat, but the seat cushion side portion of one seat is extended to the seat cushion side portion of the other seat.
The automobile seat described at the beginning is also a bench seat type seat, and according to this type of seat structure, there is an advantage that the seating property can be improved.
However, in this seat, when an armrest is provided in one of the driver seat and the passenger seat, a wide gap is formed between the rear end portion of the armrest and the rear end portion of the seat cushion, and the appearance is poor. In addition, small items placed on the seat cushion may fall through the gap to the vehicle body floor under the seat.
If the rear end of the armrest is extended to the rear side of the seat so as to eliminate the gap, there is a problem that a portion protruding to the rear of the seat occurs when the armrest is used, and the rear space of the seat becomes narrow. There's a problem.
In order to solve these problems, it is conceivable to apply the structure disclosed in Patent Document 1 to a bench seat type structure. In the structure of Patent Document 1, the upper surface of the rear end portion of the seat cushion is raised, the gap between the rear end portion of the seat cushion and the lower end portion of the seat back is narrowed, and a gap concealing cover is provided on the lower back of the lower end of the seat back. is there.

The armrest is for supporting the occupant's arm, and if the position attached to the seat back is too low, the armrest is not easy to use. Therefore, the clearance between the rear end portion of the armrest and the rear end portion of the seat cushion is wider than the clearance between the seat cushion and the seat back. When the structure of Patent Document 1 is applied to such a structure, in order to hide the gap, it is necessary to raise the upper surface of the rear end portion of the seat cushion.
However, such a structure requires a large increase in the volume of the seat cushion pad, which increases weight and material costs. And because the seat cushion trim (skin material) needs to follow the raised shape of the seat cushion pad, the seat cushion trim requires additional sewing to prevent wrinkles, resulting in reduced manufacturing efficiency. To do.
In addition, since the seat back is often a structure that can be folded and folded not only on the seat rear side but also on the seat front side, when the structure of Patent Document 2 is applied to the structure described in [Technical Field] at the beginning, When the seat back is tilted to the front side of the seat, the belt-like belt is loosened and the hidden cover is bent. In such a state, it does not look good, and there is a possibility that small articles may fall into the bending of the hidden cover.
The present invention has been made in view of the above circumstances, and the object thereof is to cover the gap between the rear end portion of the armrest and the rear end portion of the seat cushion, thereby improving the appearance quality. At the same time, it is a structure that can prevent small items from falling on the vehicle body floor behind the seat cushion, while providing a seat for automobiles that can reduce weight, reduce material costs, and improve manufacturing efficiency. is there.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 shows a bench seat type driver's seat 1 and a passenger seat 2 arranged in the front part of the interior of an automobile. The driver's seat 1 includes a seat cushion 4 that supports the buttocks and thighs of the seated person, a seat back 5 that is rotatably supported by the seat cushion 4 and supports the back of the seated person, and a head of the seated person. And a headrest 6 to be supported. Further, an armrest 7 that supports the arm of the seated person is attached to the side portion 5S of the seat back 5 on the passenger seat 2 side so as to be rotatable around the horizontal axis, and is used in a posture of use (see FIGS. 3 and 5) and standing up. It is configured to be able to switch between swinging positions (see FIGS. 2 and 4).

  As shown in FIG. 4, the seat cushion 4 includes a pipe-shaped seat cushion frame 8, a seat cushion pad 9 supported by the seat cushion frame 8, and a seat cushion trim 10 (skin material) covering them. Yes. S-shaped springs for improving seating properties are installed on both left and right ends of the seat cushion frame 8. The seat cushion pad 9 is made of urethane foam.

  The seat back 5 includes a seat back frame, a seat back pad supported by the seat back frame, and a seat back trim (skin material) that covers them.

  The armrest 7 includes an armrest frame, an armrest pad supported by the armrest frame, and an armrest trim (skin material) that covers them.

  1 to 3, the width of the seat cushion 4 is set to be longer than the width of the seat back 5, and the side portion 4 </ b> S on the passenger seat 2 side (armrest 7 side) of the seat cushion 4 is A gap S (see FIG. 4) is formed so as to protrude downward and between the rear end portion 7B of the armrest 7 and the rear end portion 4B of the seat cushion 4.

  As shown in FIG. 4, a cover member 13 covering the gap S is stretched across the rear end portion 7 </ b> B of the armrest 7 and the back side of the seat cushion 4. The cover member 13 includes a contact portion 13M that contacts the contacted surface 10M of the rear end portion 4B of the seat cushion 4. One end portion 13A of the cover member 13 is connected to the connected portion 12A of the rear end portion 7B of the armrest 7, and the other end portion 13B of the cover member 13 is a belt-like rubber band 14 (an expansion / contraction member, which provides tension). Is connected to the back side of the seat cushion 4 via a corresponding portion). In this way, the cover member 13 is set to be stretched over the entire stroke of the armrest 7 in the rotational direction.

  The cover member 13 is composed of two cloth materials 23 and 24 overlapped with each other, and is set to have substantially the same width as the armrest 7. The seat back trim, the seat cushion trim 10 and the armrest trim 12 are made of the same material, and the two cloth materials 23 and 24 are made of the same material.

  As a result, it is possible to give the occupant a sense that the seat cushion, the seat back, and the armrest 7 are integrated in appearance. . Further, since the contact between the contact portion 13M of the cover member 13 and the contacted surface 10M of the seat cushion 4 is a contact between the same materials, it is possible to easily prevent the mutual damage.

  One end portions of the two cloth materials 23 and 24 corresponding to the one end portion 13 </ b> A of the cover member 13 are sewn together to the lower end portion of the armrest trim 12. The two cloth materials 23 and 24 have the back surfaces facing each other, and the front side faces the outside. Therefore, the back surfaces of the cloth materials 23 and 24 cannot be seen, and the appearance can be improved.

  As shown in FIG. 7, the other end portions 23B and 24B of the two cloth members 23 and 24 corresponding to the other end portion 13B of the cover member 13 are folded on the back side, and a pair of folded other ends. The portions 23B and 24B sandwich the one end portion 14A of the rubber band 14. The pair of folded other end portions 23B, 24B and one end portion 14A of the rubber band 14 are sewn together. Reference numeral H denotes a sewing line.

  Thereby, the sewing force of the cover member 13 and the rubber band 14 is strengthened, and the sewn portion of the cover member 13 and the rubber band 14 is prevented from being separated by the tension of the rubber band 14 when the armrest 7 is used. (In particular, since the rubber band 14 expands and contracts every time the armrest 7 is used, a load is easily applied to the sewn portion of the cover member 13 and the rubber band 14). As a result, the durability of the cover member 13 and the rubber band 14 can be improved.

  As shown in FIGS. 4 to 6, a hook 15 as a locking member having a J-shaped cross section is sewn to the other end portion 14 </ b> B of the rubber band 14. The width of the hook 15 is set to be substantially the same as the width of the rubber band 14. The hook 15 is detachably locked to the seat cushion frame 8. Thereby, the attachment operation | work to the seat cushion frame 8 of the other end part 14B of the rubber band 14 can be performed easily, and assembly | attachment property can be improved. Since the rubber band 14 and the hook 15 are located on the back side of the seat cushion that cannot be seen by the occupant, the appearance can be improved.

  As shown in FIGS. 4 and 5, the seat cushion pad portion 9B of the rear end portion 4B of the seat cushion 4 wraps around the rear side of the pipe-shaped seat cushion frame portion 8K along the seat width direction and extends downward. Yes. The contact portion 13M of the cover member 13 and the seat cushion frame portion 8K of the rear end portion 4B of the seat cushion 4 sandwich the seat cushion pad portion 9B in an obliquely vertical direction. The contact portion 13M is positioned below and below the seat cushion frame portion 8K.

Thereby, compared with the structure where the contact portion 13M of the cover member 13 is in contact with the seat cushion frame portion 8K, the wear of the cover member 13 can be suppressed, and the durability of the cover member 13 can be improved. it can.
Further, for example, compared to a structure in which the contact portion 13M of the cover member 13 is in contact with the seat cushion pad portion 9B via the seat cushion trim 10, and the pressure applied from the cover member 13 is received only by the seat cushion pad portion 9B. The shape of the seat cushion pad portion 9B can be maintained, and the depression of the seat cushion pad portion 9B can be suppressed. Accordingly, the durability of the seat cushion pad 9 can be improved, and the smooth pulling effect of the armrest 7 can be obtained over a long period of time.

  In addition, when viewed in a longitudinal side view, the first distance D1 (see FIG. 4) from the connection portion of the connected portion 12A of the armrest 7 in the standing retracted posture to the contacted surface 10M of the seat cushion 4 is the covered distance of the armrest 7 in the use posture. It is set shorter than the second distance D2 (see FIG. 5) from the connection location of the connecting portion 12A to the contacted surface 10M of the seat cushion 4. In a longitudinal side view, the entire length L (see FIG. 4) of the cover member 13 is set to be substantially the same as the second distance D2 (see FIG. 5).

Since the total length L of the cover member 13 does not change between when the armrest 7 is in the upright retracted position and when it is in the used position, the first distance D1 is set shorter than the second distance D2 as described above. As a result, the tension applied to the rubber band 14 is smaller when the armrest 7 is in the upright retracted posture than when the armrest 7 is in the use posture.
Usually, the time when the vehicle is not used, that is, the time when the armrest 7 is in the standing storage posture is longer than the time when the vehicle is used, that is, the time when the armrest 7 is in the use posture. Therefore, the time in which the tension applied to the rubber band 14 is reduced when the armrest 7 is in the standing retracted posture is shorter than the time in which the tension applied to the rubber band 14 is increased after the armrest 7 is in the use posture. can do.
Thereby, it can avoid that a big tension | tensile_strength is added to the rubber band 14 for a long time, and the permanent elongation of the rubber band 14 can be suppressed. As a result, the durability of the rubber band 14 can be improved, the cover member 13 can be prevented from sagging, and a good appearance can be obtained over a long period of time.

  In the longitudinal side view, the entire length L of the cover member 13 is set to be substantially the same as the second distance D2 or longer than the second distance D2, as will be described later. The appearance is improved without entering the eyes and the rubber band 14 entering the eyes of the passengers. Further, since the rubber band 14 does not come into contact with the contacted surface 10M of the rear end portion 4B of the seat cushion 4, it is possible to prevent the rubber band 14 that is more easily frayed than the cover member 13 from being worn out. The durability of can be improved.

  As shown in FIG. 4, the connection location of the connected portion 12 </ b> A of the armrest 7 is positioned on the front side Fr of the seat from the lower end 7 </ b> K in the longitudinal direction of the armrest 7 in the upright retracted posture.

  Generally, the rear end of the armrest 7 in the use posture is located on the seat rear side Rr with respect to the rear end of the seat cushion 4. Therefore, according to the said structure of this invention, the 2nd distance D2 from the connection location of the to-be-connected part 12A of the armrest 7 of the said use attitude | position to the to-be-contacted surface 10M of the said seat cushion 4 can be shortened. As a result, the length of the cover member 13 can be shortened. Thus, even if the length of the cover member 13 is shortened, the gap S can be covered and the material cost required for the cover member 13 can be reduced.

  As shown in FIG. 6, the cover member 13 and the rubber band 14 are sewn with the side sides 13S and 14S aligned. Thus, when the two cloth materials 23 and 24 of the cover member 13 sandwich the one end portion 14A of the rubber band 14 and sew together, the two cloth materials 23 and 24 of the cover member 13 and the rubber band 14 can be easily combined. Positioning can be performed, sewing work can be facilitated, and productivity can be improved.

According to the present invention,
The gap S between the rear end portion 7B of the armrest 7 and the rear end portion 4B of the seat cushion 4 can be covered with the cover member 13, so that the appearance quality can be improved. Therefore, it is not necessary to raise the upper surface of the seat cushion pad 9 below the armrest 7.
As a result, weight reduction and material cost can be reduced, and the seat cushion trim 10 is caused by additional sewing for causing the seat cushion pad 10 to follow the raised portion of the rear end portion of the seat cushion pad 9 and the formation of the raised portion. Additional sewing for preventing the seat cushion trim 10 from wrinkling is not required, and a reduction in manufacturing efficiency can be avoided.
In addition, small items on the seat cushion 4 can be received by the cover member 13, and the small items can be prevented from falling on the vehicle body floor below the seat cushion 4.
The other end 13 </ b> B of the cover member 13 is connected to the back side of the seat cushion 4 via the rubber band 14 and is set in a state in which the cover member 13 is stretched over the entire stroke of the armrest 7 in the rotation direction. Therefore, the appearance quality can be further improved and the commercial value can be improved, and it is possible to more reliably prevent small articles from falling between the cover member 13 and the seat cushion 4.
