SUMMARY OF THE INVENTION It is an object of the present invention to provide a boundary covering structure for a rear seat that can omit a structure for following tilting of a seat back.

A boundary covering structure of a rear seat for solving the above-mentioned problems covers from the rear side the boundary between the seat cushion and the seat back in the rear seat in which the seat back can be tilted with respect to the seat cushion installed on the floor of the vehicle. A boundary covering structure for a rear seat, comprising: a belt-shaped member that covers the boundary from the rear side of the rear seat; a first mounting portion to which an end portion is mounted; and a second mounting portion to which the front end portion of the belt-shaped member is mounted at a position on the floor that is located on the front side of the first mounting portion and lower than the upper end of the first mounting portion. The gist is to have a part and a.

According to this, the belt-shaped member is arranged to descend from the rear end toward the front end, covering the boundary between the seat cushion and the seat back from the rear side of the rear seat, and covering the rear side of the rear seat on the floor from above. . Therefore, when the seat back is tilted forward, the boundary between the seat cushion and the seat back widens, and even if the rear side of the rear seat is visible from the front side of the rear seat through the boundary, the belt-shaped member is only visible, and the rear seat is not visible. The floor behind is not visible. Therefore, for example, even if the wiring is laid on the rear side of the rear seat on the floor, the wiring cannot be visually recognized through the boundary.

A rear end portion of the belt-shaped member is attached to a first attachment portion provided on the vehicle component, and a front end portion of the belt-shaped member is attached to a second attachment portion provided on the floor. Therefore, the strip member does not follow the tilting motion of the rear seat. Therefore, for example, when one end of the belt-shaped member is attached to the seat back and the other end of the belt-shaped member is attached to the seat cushion, the rubber cord is used to make the belt-shaped member follow the tilting motion of the seat back. No such configuration is required.

Further, with respect to the boundary covering structure of the rear seat, an anchor portion for attaching the child seat to the rear seat is arranged at the boundary between the seat cushion and the seat back, and the second attachment portion constitutes the anchor portion. It may be an anchor installation member.

According to this, the front end portion of the belt-like member can be attached using the anchor installation member that constitutes the anchor portion for attaching the child seat to the rear seat. Therefore, it is possible to cover the wiring through the boundary with the belt-shaped member without adding a second mounting portion for installing the belt-shaped member to the rear seat.

Further, with respect to the boundary covering structure of the rear seat, a rear floor as the vehicle component may be provided on the rear side of the floor, and the rear floor may constitute the first mounting portion.
According to this, by attaching the rear end of the belt-shaped member to the rear floor before fixing the rear floor to the floor at the vehicle factory, the rear end of the belt-shaped member can be arranged at the same time as the rear floor is fixed to the floor. .

A boundary covering structure of a rear seat for solving the above-mentioned problems covers from the rear side the boundary between the seat cushion and the seat back in the rear seat in which the seat back can be tilted with respect to the seat cushion installed on the floor of the vehicle. A boundary covering structure for a rear seat, comprising: a belt-shaped member that covers the boundary from the rear side of the rear seat; a first attachment portion to which an end portion is attached; and a second attachment portion to which the front end portion of the belt-shaped member is attached at a position in the seat cushion that is located on the front side of the first attachment portion and lower than the upper end of the first attachment portion. and a mounting portion.

According to this, the belt-shaped member is arranged so as to descend from the rear end portion toward the front end portion, covers the boundary between the seat cushion and the seat back from the rear side of the rear seat, and covers the rear side of the floor from the rear seat from above. cover. Therefore, when the seat back is tilted forward, the boundary between the seat cushion and the seat back widens, and even if the rear side of the rear seat becomes visible through the boundary, the belt-shaped member is only visible, and the rear side of the rear seat is visible. Floor is not visible. Therefore, for example, even if wiring is laid on the floor, the wiring cannot be visually recognized through the boundary.

According to the present invention, a structure for following tilting of the seat back can be omitted.

In the seated position where the seat back 22 functions as a backrest without tilting forward or backward, the rear end of the seat cushion 21 and the lower end of the seat back 22 are close to each other and the boundary K is narrow. However, as shown in FIG. 5, when the seat back 22 is tilted forward, the rear end of the seat cushion 21 and the lower end of the seat back 22 are separated from each other, and the boundary K widens.

The boundary covering structure of the rear seat 20 is a structure that covers and hides the widened boundary K as described above from the rear side.
As shown in FIG. 3 or FIG. 5, the boundary covering structure of the rear seat 20 includes a belt-shaped member 40 that covers the boundary K from the rear side of the rear seat 20, and a first mounting portion to which the rear end portion 40a of the belt-shaped member 40 is mounted. and an anchor installation member 24 as a second attachment portion to which the front end portion 40b of the belt-shaped member 40 is attached.

As shown in FIG. 4, the belt-shaped member 40 is formed of a rectangular belt-shaped fabric. In addition, the belt-shaped member 40 may be formed of a resin sheet other than cloth. As shown in FIG. 3 or FIG. 5, the belt-shaped member 40 is provided so that the length of the belt-shaped member 40 extends in the front-rear direction. Therefore, the short sides of the belt-like member 40 extend in the left-right direction. A rear end portion 40 a of both longitudinal ends of the belt-shaped member 40 is screwed to a mounting piece 33 integrated with the rear floor 30 . Specifically, the rear end portion 40a of the belt-shaped member 40 is attached to the mounting piece 33 by screws 51 passing through both sides in the left-right direction of the belt-shaped member 40 . installed.

The rear end portion 40a of the belt-shaped member 40 is attached to the attachment piece 33 at the factory where the rear floor 30 is manufactured. Then, by fixing the rear floor 30 to the floor 11, the belt-shaped member 40 is installed on the automobile.

The belt-like member 40 has a mounting hook 42 at its front end 40b. The mounting hooks 42 are provided along the entire length of the belt-like member 40 . The mounting hook 42 is made of resin. Also, the attachment hook 42 is sewn to the belt-shaped member 40 . The front end portion 40b of the belt-shaped member 40 is attached to the connecting portion 28 of the anchor installing member 24 by hooking the mounting hook 42 onto the connecting portion 28 of the anchor installing member 24. As shown in FIG. As described above, the upper end surface 33b of the mounting piece 33 is positioned higher than the connecting portion 28. As shown in FIG.

Next, the operation of the boundary covering structure of the rear seat 20 will be described.
In the rear seat 20, the rear end of the seat cushion 21 and the lower end of the seat back 22 are close to each other and the boundary K is narrow when the seat back 22 functions as a backrest without being tilted forward or backward.

However, as shown in FIG. 5 or 6, when the seat back 22 is tilted forward, the rear end of the seat cushion 21 and the lower end of the seat back 22 are separated from each other, and the boundary K widens. At this time, when the boundary K is viewed from the front side of the rear seat 20, the band-shaped member 40 can be visually recognized through the boundary K. Therefore, even if the boundary K between the seat cushion 21 and the seat back 22 widens and the rear side of the rear seat 20 becomes visible through the boundary K, it is the band-shaped member 40 that is visible, and the rear side of the rear seat 20 on the floor 11 is visible. is not visible. Therefore, even if the wire harness 35 is laid on the floor 11 located behind the rear seat 20, the wire harness 35 cannot be visually recognized through the boundary K.

According to the above embodiment, the following effects can be obtained.
(1) The rear end portion 40a of the strip member 40 is attached to the upper end surface 33b of the mounting piece 33 of the rear floor 30, and the front end portion 40b of the strip member 40 is attached to the connecting portion 28 of the anchor installation member 24 by the attachment hook 42. Therefore, the strip member 40 does not follow the tilting motion of the seat back 22 of the rear seat 20 . Therefore, for example, the rear end portion 40a of the strip member 40 is attached to the seat back 22 and the front end portion 40b of the strip member 40 is attached to the seat cushion 21, so that the strip member 40 follows the tilting motion of the seat back 22. Therefore, it is not necessary to provide a structure, for example, a rubber cord to the belt-like member 40 . As a result, a configuration for causing the strip member 40 to follow the tilting motion of the seat back 22 can be omitted.

(2) The attachment hooks 42 of the belt-like member 40 are attached to the anchor portions 27 of the anchor attachment member 24 for attaching the child seat C to the rear seat 20 . Therefore, the existing member for attaching the child seat C to the rear seat 20 can be used to attach the front end portion 40b of the belt-shaped member 40 to cover the rear wire harness 35 through the boundary K. Therefore, the wire harness 35 on the rear side can be covered through the boundary K without adding a second mounting portion for mounting the front end portion 40b of the belt-shaped member 40 to the rear seat 20 .

(3) The rear end portion 40a of the belt-shaped member 40 is attached to the rear floor 30 as a vehicle component. By attaching the rear end portion 40a of the strip member 40 to the rear floor 30 before fixing the rear floor 30 to the floor 11, the rear floor 30 is fixed to the floor 11 and at the same time, the rear end portion 40a of the strip member 40 is attached to the vehicle body. can be placed.
