Description

  The present invention relates to a cover mounting structure.

  2. Description of the Related Art Conventionally, a vehicle in which functional parts such as a battery are arranged in the vicinity of a vehicle seat is known (see Patent Document 1 below). In Patent Document 1, a functional component such as a battery is arranged on the rear side of the seat back.

  There is also known a vehicle in which such functional parts are arranged below the vehicle seat. Specifically, the functional component is disposed in a lower space formed below a seat cushion constituting the vehicle seat.

  Such a lower space is required to be hidden from the occupant from the viewpoint of design and the like. For this reason, the structure which covers lower space with a cover is known. Such a cover is attached to, for example, a seat frame disposed below the seat cushion. As a means for attaching the cover to the seat frame, a clip or the like is generally used.

JP 2011-31778 A

  In a configuration using a separate part such as a clip as the attachment means of the cover, the number of parts increases by the amount of the clip, resulting in a complicated configuration. Further, such a cover is disposed below the seat cushion, that is, near the top of the floor carpet covering the vehicle floor. For this reason, it can be considered that the cover is configured to press the peripheral end portion of the floor carpet from above to suppress the floating of the floor carpet. In such a configuration, the cover may be pressed upward (biased) by the reaction force of the pressed floor carpet. Thereby, there is a concern that the mounting position of the cover with respect to the seat frame is shifted from a predetermined position. That is, when pressing the floor carpet with a cover, there is a concern that the positioning accuracy of the cover will be reduced.

  The present invention has been completed based on the above circumstances, and realizes a cover mounting structure that covers the lower space of the seat cushion with a simpler configuration, and when the floor carpet is pressed by the cover. An object of the present invention is to provide a cover mounting structure capable of suppressing a situation in which the positioning accuracy of the cover is lowered.

  In order to solve the above problems, the present invention provides a cover mounting structure for mounting a cover covering a lower space formed below a seat cushion of a vehicle seat to a seat frame disposed in the lower space. The seat frame includes a rod-shaped upper frame portion extending in the vehicle width direction, and a lower frame portion formed in a rod shape extending in the vehicle width direction and disposed below the upper frame portion, and the cover A cover main body having a lower end that contacts a floor carpet covering the vehicle floor, and a plate-like cover main body, and is integrally provided on the surface of the cover main body on the seat frame side, and is locked to the lower frame And a lower locking portion integrally provided on a surface of the cover body portion on the seat frame side and locked to the upper frame portion. The upper locking portion is provided on the pedestal portion protruding from the surface on the seat frame side of the cover main body portion toward the upper frame portion, and has a shape that allows the upper frame portion to be fitted. A locking piece portion formed therein, the locking piece portion having an opening capable of receiving the upper frame portion therein, and an upper opening end portion in the opening portion of the locking piece portion Is characterized in that it can be displaced in the vertical direction, and the downward opening end of the opening of the locking piece is restricted in the vertical direction.

  According to the present invention, the cover can be attached to the seat frame by locking the lower locking portion to the lower frame portion and locking the upper locking portion to the upper frame portion. In particular, the upper locking portion can receive the upper frame portion through the opening. Thereby, the upper frame part can be fitted to the upper locking part.

  Here, the upper opening end of the opening can be displaced in the vertical direction. For this reason, when the upper frame portion passes through the opening, the upper opening end is displaced upward, so that the opening width of the opening is increased. As a result, the upper frame portion can easily pass through the opening.

  Thus, in the present invention, the cover mounting structure can be realized with a simpler configuration without using another component such as a clip.

  Moreover, the cover main-body part of this invention is contact | abutting to the floor carpet in the lower end part. Thereby, a floor carpet can be pressed down by a lower end part, and the floating of a floor carpet can be suppressed. However, with such a configuration, there is a concern that the cover main body may be pressed upward (biased) by the reaction force of the floor carpet that is pressed down.

  Therefore, the lower opening end of the opening is configured to be restricted from bending displacement in the vertical direction. With such a configuration, the rigidity of the lower part of the locking piece is relatively high. As a result, when the cover main body portion is pressed upward in a state where the upper frame portion is fitted to the locking piece portion, the lower portion of the highly rigid locking piece portion is positioned below the upper frame portion. Abut. Thereby, the upward displacement of a cover main-body part can be controlled more reliably. Thus, in this invention, when pressing a floor carpet with a cover, the situation where the positioning accuracy of a cover falls can be suppressed.

  In the above configuration, the upper frame portion has a circular shape in cross section, and the locking piece portion has a C-shape having the opening opened to the upper frame portion side, and the locking piece The portion has an upper piece extending from the pedestal portion so as to cover the upper frame portion from above, and a lower piece portion extending from the pedestal portion so as to cover the upper frame portion from below. The tip of the upper piece constitutes the upper opening end of the opening, and the tip of the lower piece constitutes the lower opening end of the opening It can be.

  With such a configuration, the engagement piece portion can be more reliably positioned with respect to the upper frame by fitting the upper frame having a circular shape in cross section with the engagement piece portion having a C-shape. it can.

  Further, at least three upper locking portions are arranged along the extending direction of the upper frame portion, and the upper locking portion arranged on the center side among the three upper locking portions is The opening width of the opening portion may be set larger than the two upper locking portions disposed on both sides of the opening portion.

  As in the present invention, in a configuration including at least three upper locking portions, if an attempt is made to lock each upper locking portion to the upper frame portion at the same time, the force required for the locking operation becomes larger. Workability is reduced. For this reason, it is preferable that each upper locking part is locked to the upper frame part one by one in order.

  Here, as an order of locking the three upper locking portions, it is preferable to lock the outer upper locking portions first. That is, it is preferable that after locking one of the two upper locking portions disposed on both sides, the upper locking portion disposed on the center side is locked. This is because, generally, it is easier to apply a force and the workability is better when the upper locking portion arranged on the outside is locked first. Also, if the upper side locking portion on the center side is locked first, as a result of the upper side locking portions on both sides approaching the upper frame portion, it is necessary to simultaneously perform the locking operation of the upper side locking portions on both sides, The force required for the locking operation increases.

  In consideration of the order of the locking operation as described above (after locking the outer upper locking portion, the upper locking portion on the center side is locked), the present invention has three upper locking portions. Among them, the opening width of the opening portion of the upper locking portion disposed on the center side is set to be larger than the opening width of the upper locking portion disposed on both sides thereof (the upper locking portion disposed on the outside). It was decided.

  When the opening width of the opening is large, it is easy to pass the upper frame portion, and therefore the force required to lock the upper locking portion is reduced. The order of the upper locking portion (referred to as the first upper locking portion in the following description) disposed on the outside and the upper locking portion (referred to as the second upper locking portion in the following description) disposed on the center side In the process of performing the locking operation at, the second upper locking portion approaches the upper frame portion in the middle of locking the first upper locking portion, and the locking operation of the second upper locking portion is started. Sometimes. In this case, in addition to the force for locking the first upper locking portion, a force for locking the second upper locking portion is required, which tends to increase the burden on the operator.

  For this reason, in the present invention, by increasing the opening width of the second upper locking portion, the force required to lock the second upper locking portion is further reduced, and the first upper locking portion is locked. The burden on the operator when the locking operation of the second upper locking portion is started in the middle can be reduced, and the workability can be further improved.

  ADVANTAGE OF THE INVENTION According to this invention, the attachment structure of the cover which covers the downward space of a seat cushion is realizable with a simpler structure.

  The cover 40 (seat undercover) is made of, for example, a synthetic resin and has a plate-like cover main body 41 and a lower locking portion 51 provided on the back surface of the cover main body 41 (surface on the seat frame 20 side). And an upper locking portion 61 provided on the back surface of the cover main body portion 41. The lower locking portion 51 and the upper locking portion 61 are formed integrally with the cover main body portion 41. The material of the cover 40 is not limited to the synthetic resin and can be changed as appropriate. For example, the cover 40 may be made of a material in which fibers and a synthetic resin are mixed.

  As shown in FIG. 2, the cover main body 41 has a substantially square plate shape that is long in the vehicle width direction. The upper part of the cover main body 41 is inclined so as to go rearward as it goes upward. The cover body 41 is arranged to close the opening S2 of the lower space S1 and covers the battery 14 from the front side of the vehicle.

  As shown in FIG. 3, the lower end portion 41 </ b> A of the cover main body portion 41 has a shape extending forward of the vehicle. As shown in FIG. 3, the lower end portion 41 </ b> A comes into contact with the peripheral end portion of the floor carpet 16 placed so as to cover the floor panel 15 constituting the vehicle floor from above.

  The lower locking portions 51 are locked to the lower frame portion 22, and as shown in FIG. 2, a plurality (two in this embodiment) are arranged along the vehicle width direction. As shown in FIG. 3, the lower locking portion 51 is provided on the pedestal portion 52 that protrudes from the back surface of the cover main body portion 41 toward the lower frame portion 22, and the pedestal portion 52. And a locking piece portion 53 to be fitted.

  The locking piece 53 has a U-shape having an opening 53 </ b> A that opens downward, and the inner surface thereof follows the shape of the outer peripheral surface of the lower frame portion 22. Thereby, it is possible to attach the locking piece portion 53 to the lower frame portion 22 from above.

  Further, an extended piece portion 54 is provided at an end portion of the locking piece portion 53 on the vehicle rear side so as to incline toward the rear of the vehicle as it goes downward.

  The upper locking portion 61 is locked to the upper frame portion 21, and as shown in FIG. 2, a plurality (four in this embodiment) are arranged along the vehicle width direction. As shown in FIG. 4, the upper locking portion 61 is provided on the pedestal portion 62 that protrudes from the back surface of the cover main body portion 41 toward the upper frame portion 21, and the pedestal portion 62. And a locking piece portion 63 to be provided.

  As shown in FIG. 2, the pedestal portion 62 has a shape in which one side in the vehicle width direction is opened, and has a bottom wall portion 62 </ b> A and a side wall portion 62 </ b> B as shown in FIG. 4.

  The locking piece 63 has a C-shape (a ring with ends) having an opening 63A that opens toward the rear side of the vehicle (upper frame 21 side). That is, the locking piece 63 has a shape in which the upper frame portion 21 can be fitted. The locking piece 63 is connected to the end of the bottom wall 62A and the end of the side wall 62B. Further, the inner peripheral surface of the locking piece portion 63 is a curved surface along the outer peripheral surface of the upper frame portion 21. Accordingly, the outer peripheral surface of the upper frame portion 21 is in contact with the inner peripheral surface of the locking piece portion 63.

  Specifically, as shown in FIG. 4, the locking piece portion 63 includes an upper piece portion 64 that extends from the pedestal portion 62 so as to cover the upper frame portion 21 from above, and a downward movement of the upper frame portion 21 from the pedestal portion 62. And a lower piece 65 extending in a covering manner.

  The upper piece 64 mainly constitutes the upper half of the locking piece 63. The lower piece 65 mainly constitutes the lower half of the locking piece 63. The opening 63A is a gap formed between the tip 64A of the upper piece 64 and the tip 65A of the lower piece 65.

  That is, the tip 64A of the upper piece 64 constitutes the upper opening end of the opening 63A, and the tip 65A of the lower piece 65 constitutes the lower opening end of the opening 63A. It is said.

  In the present embodiment, the upper piece 64 (including the tip 64A) can be elastically bent and deformed in the vertical direction with the joint portion with the pedestal 62 as a base point. That is, the tip 64A of the upper piece 64 can be deflected in the vertical direction.

  As shown in FIG. 4, the upper locking portion 61 of the present embodiment includes a connecting rib 66 (connecting portion) that connects the lower surface of the lower piece 65 and the bottom wall portion 62 </ b> A of the pedestal portion 62. As a result, the lower piece 65 is restricted from bending in the vertical direction. In other words, the vertical displacement of the tip 65A of the lower piece 65 is restricted.

  In other words, the upper part (upper piece part 64, one end side of the C-shape) of the locking piece part 63 of the present embodiment can be bent and deformed, and the lower part (lower piece part 65, the other end of the C-shape). Side) deformation is restricted.

  The cover 40 of the present embodiment includes the four upper locking portions 61 as described above. As shown in FIG. 2, among the four upper locking portions 61, the opening width B1 (opening direction of the opening 63A) of the opening 63A of two upper locking portions 61 (indicated by reference numeral 61A) arranged on the inner side. Is set larger than the opening width B2 of the opening 63A of the two upper locking portions 61 (labeled 61B) disposed on both sides thereof.

  In other words, among the three upper locking portions 61A, 61B, 61B, the upper locking portion 61A (one of the two upper locking portions 61A) arranged on the center side is on both sides (the cover body portion). The opening width of the opening 63A is set large with respect to the upper locking portions 61B and 61B arranged on the outer peripheral end side of 41.

  In the present embodiment, the opening width B1 and the opening width B2 of the opening 63A in the natural state (the state shown in FIG. 4) are set smaller than the diameter (outer diameter) of the upper frame portion 21.

  Next, a procedure for attaching the cover 40 to the seat frame 20 will be described. The operator first locks the two lower locking portions 51 with respect to the lower frame portion 22. Specifically, as shown in FIG. 5, the lower frame portion 22 is inserted into the locking piece portion 53 through the opening 53 </ b> A of the locking piece portion 53. That is, the lower frame portion 22 is fitted to the locking piece portion 53.

  When the lower frame portion 22 is inserted into the locking piece portion 53, the extended frame portion 54 is brought into contact with the lower frame portion 22 so that the lower frame portion 22 is engaged with the locking piece portion. 53 is guided to the inside.

  By fitting the lower frame portion 22 into the locking piece portion 53, the cover 40 can be rotated around the lower frame portion 22.

  Next, the operator rotates the cover 40 so that the upper end portion of the cover 40 approaches the upper frame portion 21. Accordingly, each of the upper locking portions 61 approaches the upper frame portion 21, and each locking piece portion 63 is locked to the upper frame portion 21.

  In the process of the locking operation of the locking piece 63, the distal end portion 64 </ b> A of the upper piece 64 contacts the upper frame portion 21. When the operator further presses the cover main body 41 toward the upper frame portion 21 from this state, the distal end portion 64A pressed by the upper frame portion 21 is deflected upward and displaced as shown in FIG.

  As a result, as shown in FIG. 6, the opening width of the opening 63A (B1 in FIG. 6) is larger than the diameter of the upper frame portion 21, and the upper frame portion 21 can pass through the opening 63A. As a result, the upper frame portion 21 can be fitted to the locking piece portion 63.

  When the upper frame portion 21 is accommodated inside the locking piece portion 63, the distal end portion 64A is elastically restored to a natural state (a state before deformation). Thereby, the opening width of the opening 63 </ b> A becomes smaller than the diameter of the upper frame portion 21. As a result, the upper frame portion 21 is held inside the locking piece portion 63. Thereby, the attachment of the cover 40 to the seat frame 20 is completed.

  Next, the effect of this embodiment will be described. According to this embodiment, the lower locking portion 51 is locked to the lower frame portion 22, and the upper locking portion 61 is locked to the upper frame portion 21 so that the cover 40 is attached to the seat frame 20. Can be attached. In particular, in the upper locking portion 61, the upper frame portion 21 can be received inside through the opening 63A. Thereby, the upper frame part 21 can be fitted to the upper locking part 61.

  Here, the distal end portion 64A of the upper piece 64 constituting the opening 63A can be deflected in the vertical direction. For this reason, when the upper frame portion 21 passes through the opening 63A, the distal end portion 64A of the upper piece 64 is displaced upward, so that the opening width of the opening 63A is increased. As a result, the upper frame portion 21 can easily pass through the opening 63A.

  Thus, in this embodiment, the attachment structure of the cover 40 can be realized with a simpler configuration without using another component such as a clip.

  Further, the cover main body 41 of the present embodiment is in contact with the floor carpet 16 at the lower end 41A. Thereby, the floor carpet 16 can be pressed by the lower end portion 41 </ b> A, and the floating of the floor carpet 16 can be suppressed. However, in such a configuration, there is a concern that the cover main body 41 is pressed upward by the reaction force of the floor carpet 16 that is pressed down. Thereby, for example, the cover 40 is displaced upward from a predetermined mounting position, and there is a concern that the positioning accuracy of the cover 40 with respect to the seat frame 20 is lowered.

  Therefore, in the present embodiment, the distal end portion 65A of the lower piece 65 constituting the opening 63A is configured to be restricted from bending displacement in the vertical direction. With such a configuration, the rigidity of the lower part of the locking piece 63 is relatively high. As a result, when the cover main body 41 is pressed upward in a state where the upper frame portion 21 is fitted to the locking piece portion 63, the lower lower piece portion 65 (the lower portion of the locking piece portion) is pressed. ) Comes into contact with the upper frame portion 21 from below. Thereby, the upward displacement of the cover main body 41 can be more reliably regulated. Thus, in this embodiment, when the floor carpet 16 is pressed down with the cover 40, the situation where the positioning accuracy of the cover 40 falls can be suppressed.

  Further, the upper frame portion 21 has a circular shape in sectional view, and the locking piece portion 63 has a C-shape having an opening 63A opened on the upper frame portion 21 side. And an upper piece 64 extending from the pedestal 62 so as to cover the upper frame portion 21 from above, and a lower piece 65 extending from the pedestal 62 so as to cover the upper frame portion 21 from below. The tip 64A of the upper piece 64 constitutes the upper opening end of the opening 63A, and the tip 65A of the lower piece 65 constitutes the lower opening end of the opening 63A. The

  With such a configuration, by engaging the upper frame portion 21 having a circular shape in cross-section with the C-shaped locking piece portion 63, the locking piece portion 63 is made more tight with respect to the upper frame portion 21. Positioning can be ensured.

  Further, at least three upper locking portions 61 are arranged along the extending direction of the upper frame portion 21, and among the three upper locking portions 61A, 61B, 61B, the upper locking portions are arranged on the center side. The opening width of the opening 63A is set larger than that of the two upper locking portions 61B and 61B arranged on both sides of the portion 61A.

  In the configuration including a plurality (at least three) of the upper locking portions 61 as in the present embodiment, if each upper locking portion 61 is locked to the upper frame portion 21 at the same time, the locking operation is performed. The required force becomes larger and workability is reduced. For this reason, it is preferable that each upper locking part 61 is locked to the upper frame part 21 one by one.

  As an order of locking the plurality of upper locking portions 61, it is preferable to lock the outer upper locking portions 61B first. That is, after locking one of the two upper locking portions 61B and 61B arranged on both sides, the upper locking portion 61A (of the two upper locking portions 61A, It is preferable to lock the upper locking portion 61A adjacent to the locked upper locking portion 61B.

  This is because, generally, it is easier to apply a force to the upper locking portion 61B disposed on the outside first, and the workability is improved. Also, if the upper side locking portion 61A on the center side is locked first, the upper side locking portions 61B and 61B on both sides approach the upper frame portion 21, so that the upper side locking portions 61B and 61B on both sides are locked. The work needs to be performed simultaneously, and the force required for the locking work increases.

  In consideration of the order of the locking operation as described above (after locking the upper locking portion 61B, the upper locking portion 61A is locked), in the present embodiment, the three upper locking portions 61A, Of 61B and 61B, the opening width B1 of the opening 63A of the upper locking portion 61A arranged on the center side is made larger than the opening width B2 of the other upper locking portion 61B (upper locking portion arranged on the outside). We decided to set a larger value.

  If the opening width of the opening 63A in the natural state is large, the amount of bending the upper piece 64 is small, and the upper frame portion 21 can be easily passed. Therefore, it is necessary to lock the upper locking portion 61. The power is reduced. In the process of performing the locking operation in the order of the upper locking portion 61B (first upper locking portion) disposed on the outer side and the upper locking portion 61A (second upper locking portion) disposed on the center side, In the middle of locking the locking portion 61B, the upper locking portion 61A adjacent to the upper locking portion 61B may approach the upper frame portion 21 and the locking operation of the upper locking portion 61A may be started. In this case, in addition to the force for locking the upper locking portion 61B, a force for locking the upper locking portion 61A is required, which tends to increase the burden on the operator.

  For this reason, in the present embodiment, by increasing the opening width B1 of the opening 63A of the upper locking portion 61A, the force required to lock the upper locking portion 61A is further reduced, and the upper locking portion 61B. It is possible to reduce the burden on the operator when the locking operation of the upper locking portion 61A is started in the middle of locking, and the workability can be further improved. In the present embodiment, the force required to lock the upper locking portion 61 means that the upper piece 64 is bent upward so that the opening width of the opening 63A is larger than the diameter of the upper frame portion 21. This is the power required to make it larger.
