Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cover structure of a side cover that covers a side portion of a seat cushion of a vehicle seat, and a vehicle seat provided with the cover structure.

A vehicle seat is known in which one end of a seat belt is attached to a side portion of a seat cushion (for example, Patent Document 1). In the vehicle seat of Patent Document 1, one end of the seat belt is provided with a one-end mounting portion, and the one-end mounting portion is mounted on a seat belt mounting member provided on an upper rail.

A side portion of the seat cushion is provided with a shield cover (side cover) that covers the one end attachment portion and the seat belt attachment member. The shield cover includes a main body having an opening insertion hole, and a movable cover member covering a part of the opening insertion hole. The open insertion hole is provided at a position aligned with the seat belt attachment member. The seat belt passes through the opening insertion hole and is coupled to the seat belt attachment member at one end attachment portion.

The movable cover member is rotatably supported by the main body on one shaft. Thereby, the movable cover member can be displaced between a covering state position covering the one end mounting portion and an exposing state position exposing the one end mounting portion. When attaching the seatbelt, the worker can attach the one-end attachment portion to the seatbelt attachment member by placing the movable cover member in the exposed position. Further, by rotating the movable cover member to the covered position after the seat belt is assembled, the one end mounting portion is not exposed, and the design of the lower side portion of the vehicle seat can be improved.

At this time, as shown in FIG. 6, the first arm portion 34A of the first operating lever 32A is coupled to the reclining device 31A.

When attaching the cover main body 62, the operator passes the first arm portion 34A through the opening 61 and then hooks the hooking piece 84 to the wire member 51 from above. After that, the cover main body 62 is rotated downward, and the clip 81B provided at the tip of the main body locking portion 81 is inserted into the bracket locking hole 53, thereby coupling the main body locking portion 81 and the locking bracket 50 together. At the same time, the operator engages the outer engaging portion 126 of the cover body 62 with the corresponding inner engaging portion 124 . As a result, the cover main body 62 is engaged with the left side frame 15 , the upper edge, the front portion, and the rear portion of the seat cushion 5 , and the cover main body 62 is coupled to the side frame 15 .

Next, the operator joins the second arm portion 34C and the second grip portion 35C, and then joins the rear end of the second arm portion 34C to the input shaft 41 of the height adjustment device 31C (see FIG. 7). After that, the operator assembles the lid portion 63 to the cover main body 62 .

When assembling the lid portion 63, the operator first engages the upper locking piece 100 with the upper edge of the opening 61 from the right side. After that, the operator rotates the lid portion 63 downward to insert the lower locking piece 104 into the lower locking hole 93 . At this time, the insertion portion 105 is elastically deformed so that the claw portion 106 is pushed toward the inner hole of the insertion portion 105, and after the insertion is completed, the insertion portion 105 returns to its original state. As a result, the claw portion 106 is hooked to the edge defining the lower locking hole 93 , and the lower locking piece 104 is coupled to the lower locking hole 93 . By engaging and rotating the upper locking piece 100 (hinge coupling portion) and engaging the lower locking hole 93 (elastic engaging portion) in this way, the assembly of the lid portion 63 is completed. Therefore, assembly of the lid portion 63 is easy.

When the assembly of the lid portion 63 is completed, the operator attaches the first grip portion 35A to the front end of the first arm portion 34A. This completes the assembly of the side cover 33 .

Next, the effect of the cover structure 1 according to this embodiment will be described. As shown in FIG. 8, when the lid portion 63 is coupled to the cover main body 62, the upper locking pieces 100 (middle upper locking piece 100B and rear upper locking piece 100B and rear upper locking piece 100B) are arranged in front and rear of at least one outer locking portion 126. 100C) are arranged. Thereby, the cover main body 62 and the inner cover 64 are joined between the adjacent upper locking pieces 100 . As a result, the connecting portion between the cover main body 62 and the lid portion 63 is supported by the inner cover 64, and the rigidity of the connecting portion between the cover main body 62 and the lid portion 63 can be increased.

As shown in FIG. 1 , the cover structure 1 locks the lid portion 63 to the cover body 62 at the upper engaging portion 97 and the lower engaging portion 98 . As a result, the lid portion 63 is locked to the cover body 62 on both the upper side and the lower side, and the connection between the lid portion 63 and the cover body 62 is strengthened, and the lid portion 63 is prevented from coming off from the opening 61. be done.

As shown in FIG. 4, an upper engaging portion 97 and a lower engaging portion 98 are provided on the upper edge and lower edge of the flat lid body 96, respectively, so that the lid body 96 and the cover body 62 are separated from each other. can be elastically coupled firmly and stably.

As shown in FIG. 1, the first operating lever 32A and the second operating lever 32C are provided at positions substantially aligned with each other in the front-rear direction. As a result, the width of the vehicle seat 2 in the left-right direction can be made smaller than when the first operating lever 32A and the second operating lever 32C are arranged side by side. Also, for example, it is possible to change the design such as widening the seating surface 9 in the left-right direction.

The upper engagement portion 97 includes a plurality of upper locking pieces 100, and the upper edge of the lid portion 63 is locked to the upper edge of the opening 61 at a plurality of points.
