Description

  The present invention relates to a vehicle seat including a seat cushion, a seat back, and a fixing member that does not follow the movement of one of the seat cushion and the seat back.

  As this type of vehicle seat, a vehicle seat including a seat cushion, a seat back, a reclining mechanism, and a reclining cover (corresponding to a fixing member) is known (see Patent Document 1). Each of the seat cushion and the seat back includes a seat pad that elastically supports an occupant by forming a seat outer shape, and a bag-like seat cover that covers the seat pad. The reclining mechanism portion is a substantially cylindrical mechanism extending in the seat width direction, and connects the lower portion of the seat back to the rear portion of the seat cushion so as to be tilted. The reclining cover is a resin flat plate member having a substantially semicircular portion covering the reclining mechanism portion, and is attached to a seat cushion to cover the reclining mechanism portion from the side.

  In the above-described seat configuration, there is a concern that the lower part of the seat cover of the seat back may be caught in the reclining cover when the seat back is tilted with respect to the seat cushion. Therefore, in the technique of Patent Document 1, the lower part of the seat cover is separated from the reclining cover using a fan-shaped trim cord. That is, the lower portion of the seat cover of the seat back is attached to the upper edge of the trim cord, and the lower edge side of the trim cord is hooked to the upper portion of the reclining cover so as to be relatively movable. In this way, when the seat back is tilted, the lower portion of the seat cover moves around the trim cord while being separated from the reclining cover.

  By the way, in the field of vehicle seats, for example, the reclining cover may be disposed so as to protrude into the movement path of the seat cover, for example, by increasing the size of the reclining cover before and after the seat. When the seat back is raised and lowered, the front end or the rear end of the seat cover tends to interfere with the reclining cover that is arranged in the movement path. However, the known technique does not assume a situation in which the reclining cover is arranged in the middle of the movement path of the seat cover. For this reason, in the configuration of the known technology, when the seat back is tilted, the front end or the rear end of the seat cover interferes with the reclining cover and cannot move from there and sometimes rises up. The present invention has been devised in view of the above points, and a problem to be solved by the present invention is to allow the end portion of the seat cover to preferably follow the relative movement of the seat constituent member with respect to the fixing member. .

  As means for solving the above-mentioned problems, a vehicle seat of the first invention includes a seat cushion, a seat back, and a fixing member that does not follow the movement of any one of the seat constituent members of the seat cushion and the seat back. . In the present invention, when the one sheet constituent member and the fixing member move relative to each other, the end of the seat cover covering the one sheet constituent member moves following the relative movement of the one sheet constituent member, Try to interfere with the fixed member at the destination. Since there is a concern that the end of the seat cover may not move due to interference with the fixing member, this type of configuration suitably follows the end of the seat cover following relative movement of the seat constituent member. It is desirable to make it. Therefore, in the present invention, at least one of the one sheet constituent member and the fixing member is provided with a continuation structure for continuing the movement of the end portion of the seat cover during the relative movement. In the present invention, it is possible to avoid curling caused by interference with the fixing member as much as possible by causing the end portion of the seat cover to suitably follow the relative movement of the seat constituent member with respect to the fixing member by the continuous structure.

  The vehicle seat of the second invention is the vehicle seat of the first invention, wherein the end portion of the seat cover moves following the relative movement of one of the seat constituent members and at a predetermined position during the movement. Try to interfere with the fixed member. Therefore, in the present invention, a linear or planar continuation means that is connected to the end of the seat cover and extends ahead of a predetermined position when viewed in the moving direction is provided on the seat cover of one of the seat constituent members. In the relative movement, the movement of the end of the seat cover is continued while passing through a predetermined position by pulling by the continuation means. In the present invention, by providing the seat cover with the continuation structure, the end portion of the seat cover can suitably follow the relative movement of the seat constituent member with respect to the fixing member without changing the configuration of the fixing member as much as possible.

  According to the first aspect of the present invention, the end portion of the seat cover can suitably follow the relative movement of the seat constituent member with respect to the fixing member. According to the second aspect of the invention, the end portion of the seat cover can be made to follow the relative movement of the seat constituent member with respect to the fixed member with a simpler configuration.

<Example 2>
Since the vehicle seat 2A of the present embodiment has substantially the same basic configuration as the vehicle seat 2 of the first embodiment, the common structure is denoted by the corresponding reference numerals and detailed description thereof is omitted. The seat cushion 4 of the present embodiment, with reference to FIGS. 9 and 10, a basic configuration 4F, 4P, and 4S, the lifter mechanism LM, a shield member 10A (an example of a fixing member), the continuation structure 30A. The lifter mechanism LM is a mechanism that moves the seat cushion 4 up and down, and includes a pair of link arms 2l and 4l. Each of the pair of link arms 21 and 41 is a substantially rectangular flat plate material, and is rotatably attached to a slide rail (not shown) on the vehicle floor surface side and a seat frame 4F of the seat cushion 4. Then, when the pair of link arms 2l and 4l rises from the fallen state, the seat cushion 4 is displaced to an upper position indicated by a solid line in FIGS. 9 and 10 and a lower position indicated by a two-dot broken line. Further, the shield member 10A is a substantially rectangular flat plate material, and an upper edge side thereof is bent inward of the sheet and disposed at a predetermined position (X). This shield member 10 </ b> A is attached to the slide rail, for example, and has a configuration that does not follow the vertical movement of the seat cushion 4.

The seat cover 4S of the seat cushion 4, referring to FIG. 10, the seat pad 4P is a bag-shaped plate member that can be coated. The seat cover 4S has an opening on the bottom side, and a lower end thereof is disposed along the periphery of the seat pad 4P. In the present embodiment, when the seat cushion 4 is in the upper position, the end E of the seat cover 4S is disposed above the shield member 10A, and the upper end of the shield member 10A gradually increases as the seat cushion 4 moves to the lower position. Approaches the predetermined position (X) to be placed and tries to interfere with it. Further, the continuation structure 30A is a face material that is provided at the end E of the seat cover 4S and extends below the seat. The upper part of the continuation structure 30A is sewn to the end E of the seat cover 4S, and the lower part of the continuation structure 30A is fixed to the seat pad 4P. In this embodiment, the lower end of the continuation structure 30A is fixed to the seat pad 4P while extending downward beyond a predetermined position (X).

Referring to FIG. 9 , seat cushion 4 is displaced from the upper position to the lower position via lifter mechanism LM. At this time, only the seat cushion 4 slides in the vertical direction, and the shield member 10A is fixed to the slide rail and does not follow the seat cushion 4. On the other hand, referring to FIG. 10 , the seat cover 4S of the seat cushion 4 moves downward in accordance with the relative movement of the seat cushion 4 with respect to the shield member 10A. For this reason, due to the relative movement of the seat cushion 4, the end E of the seat cover 4S tends to interfere with the upper end of the shield member 10A disposed at the predetermined position (X) as the movement destination.

  Therefore, in this embodiment, the seat cover 4S is provided with a planar continuous structure 30A that is connected to the end E of the seat cover 4S and extends in front of the predetermined position (X) when viewed in the moving direction. The continuation structure 30A is fixed to the seat pad 4P at the lower end, and can move together with the seat pad 4P when the seat cushion 4 is relatively moved. For this reason, at the time of relative movement of the seat cushion 4, the end E of the seat cover 4S can be continuously moved while being passed through a predetermined position by traction by the continuation structure 30A. For this reason, also in the present embodiment, the end portion E of the seat cover 4S can suitably follow the relative movement of the seat cushion 4 with respect to the shield member 10A.

  The vehicle seat of the present embodiment is not limited to the above-described embodiment, and can take other various embodiments. For example, in the present embodiment, the configuration (shape, size, arrangement position, number of arrangements, etc.) of the continuation structure 30 is exemplified, but the configuration of the structure is not intended to be limited. For example, the continuation structure may be configured by a linear member in addition to a planar shape as long as the end portion of the seat cover can be pulled. Moreover, as long as the edge part of a seat cover can be pulled, the continuation structure may be attached to the back surface side of the seat cover, and may be continuously connected to the terminal of the seat cover 6S. In this case, the end of the seat cover passes through the fixing member while being pulled by the continuous structure. The continuation structure can be detachably or non-detachably attached to the end portion of the seat cover by a physical method such as adhesion, fusion, surface fastener, line fastener, or staple.

In the present embodiment, the example in which the continuation structure 30 is provided on the seat cover 6S (the seat cover 4S and the seat pad 4P of the seat cushion) has been described. However, the continuation structure has at least one of a seat component member and a fixing member. Can be provided. For example, referring to FIG. 4 , the second fitting portion 16b of the inner shield 12 can be provided with a passage (hole or notch) as a continuous structure that allows passage of the end E of the seat cover 6S. . Further, the second fitting portion itself can be formed into a shape that does not interfere with the movement path of the end portion of the seat cover (the shape of the second fitting portion itself is a continuous structure). And the structure of the modification of this fixing member and the structure of each Example of a sheet | seat structural member can be combined suitably, and can be used.

  Moreover, in this embodiment, although the structure of the seat cushion 4 and the seat back 6 was illustrated, the structure of these seat structural members can be changed suitably. Moreover, although the shield member 10 was illustrated as an example of a fixing member, the various members which do not follow the movement of one sheet | seat structural member can be illustrated as a fixing member. Further, the configuration of the present embodiment is such that the sheet component member follows the relative movement of the fixed member such as rotational movement and slide movement (vertical movement, forward and backward movement, movement in the sheet width direction) and the like. Applicable when there is a cover edge. In addition to the recliner and lifter mechanism, various mechanisms such as a seat rail and a tilt mechanism can be exemplified as the mechanism for moving the seat constituent member. And the structure of this embodiment is applicable to vehicle seats, such as a vehicle, an aircraft, and a train.
