Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, for example, a clip of a harness assembled to an assembly target part in a manufacturing factory of vehicle parts and a clip of a harness assembled to the same assembly target part in a manufacturing factory of a vehicle are the same, and when the assembly holes of the respective clips in the assembly target part are adjacent to each other, incorrect assembly may occur in the clip of the harness assembled first in the manufacturing factory of vehicle parts.

[0005] The present invention aims to provide a harness clip misassembly prevention structure and a vehicle seat that can prevent misassembly even when two assembly holes into which two harness clips are assembled are formed adjacent to the component to be assembled. [Means for solving the problem]

[0006] The harness clip misassembly prevention structure of the first embodiment comprises: a component to be assembled, which is attached to an interior member of a vehicle and has a first assembly hole and a second assembly hole formed adjacent to each other; a first clip attached to a first harness and inserted into the first assembly hole from one side of the component to be assembled and assembled to the component; a second clip attached to a second harness and inserted into the second assembly hole from the other side of the component to be assembled and assembled to the component; and a misassembly prevention portion that protrudes from the component to be assembled toward one side around the second assembly hole.

[0007] In the harness clip misassembly prevention structure of the first embodiment, a first assembly hole and a second assembly hole are formed adjacent to each other on the assembly target part that is attached to the interior member of the vehicle. The first clip attached to the first harness is inserted into the first assembly hole from one side of the assembly target part, and the first clip is assembled to the assembly target part. The second clip attached to the second harness is inserted into the second assembly hole from the other side of the assembly target part, and the second clip is assembled to the assembly target part. A misassembly prevention portion is provided around the second assembly hole, protruding from one side of the assembly target part, so that the first clip can be prevented from being misassembled into the second assembly hole from one side.

[0008] In the second embodiment of the harness clip misassembly prevention structure, in the first embodiment, the area around the second assembly hole in the component to be assembled is a recessed area that is recessed toward the other side when viewed from the one side.

[0009] In the harness clip misassembly prevention structure of the second embodiment, the area around the second assembly hole in the component to be assembled is a recessed area that is recessed toward the other side of the component when viewed from one side of the component to be assembled, making it even easier to prevent the first clip from being misassembled into the second assembly hole.

[0010] The harness clip misassembly prevention structure of the third embodiment is such that, in the first embodiment or the second embodiment, the misassembly prevention portion is a pair of projections arranged on opposite sides of each other via the second assembly hole.

[0011] In the harness clip misassembly prevention structure of the third embodiment, a pair of protrusions, which are located on opposite sides of each other via a second assembly hole, protrude toward one side of the component to be assembled. This effectively prevents the first clip from being misassembled into the second assembly hole.

[0012] The harness clip misassembly prevention structure of the fourth embodiment is such that, in the first embodiment or the second embodiment, the misassembly prevention portion is a rib extending in a direction perpendicular to the through-direction of the second assembly hole.

[0013] In the harness clip misassembly prevention structure of the fourth embodiment, a rib extending in a direction perpendicular to the through-direction of the second assembly hole protrudes to one side of the component to be assembled. This effectively prevents the first clip from being misassembled into the second assembly hole.

[0014] The harness clip misassembly prevention structure of the fifth embodiment is such that, in the first embodiment or the second embodiment, the misassembly prevention portion is an annular protrusion that protrudes from the edge of the second assembly hole.

[0015] In the harness clip misassembly prevention structure of the fifth embodiment, an annular projection protrudes from the edge of the second assembly hole toward one side of the component to be assembled. This effectively prevents the first clip from being misassembled into the second assembly hole.

[0016] The sixth embodiment of the vehicle seat comprises a seat body on which a vehicle occupant sits and on which the first harness and the second harness are routed, and a harness clip misassembly prevention structure of any one of the first to fifth embodiments, on which the assembly target component is assembled to the seat body, and the first clip attached to the first harness and the second clip attached to the second harness are assembled to the assembly target component.

[0017] In the sixth embodiment of the vehicle seat, a first harness and a second harness are routed to the seat body on which the vehicle occupant sits. The seat body is fitted with assembly components that constitute a harness clip misassembly prevention structure. These assembly components are fitted with a first clip attached to the first harness and a second clip attached to the second harness. Since the harness clip misassembly prevention structure is one of the first to fifth embodiments, the aforementioned effects are obtained. [Effects of the Invention]

[0018] As described above, the harness clip misassembly prevention structure and vehicle seat according to the present invention can prevent misassembly even when the two assembly holes into which the two harness clips are assembled are formed adjacent to the component to be assembled.

Mode for Carrying Out the Invention

[0020] Hereinafter, a vehicle seat 10 according to an embodiment of the present invention will be described with reference to FIGS. 1 to 11. In each figure, some reference numerals may be omitted for ease of viewing the drawings. Also, the arrows FR, LH, and UP appropriately shown in each figure indicate the front, left, and upper directions of the vehicle seat 10, respectively. Hereinafter, when simply explaining using the directions of front, rear, left, right, up, and down, it shall indicate the direction with respect to the vehicle seat 10.

[0021] As shown in Figure 1, the vehicle seat 10 according to this embodiment includes a seat body 12 on which the occupant of the vehicle sits. The seat body 12 has a seat cushion 14 that supports the occupant's buttocks and thighs, a seat back 16 that supports the occupant's back, and a headrest 18 that supports the occupant's head. This vehicle seat 10 is a so-called power seat, and the seat cushion 14 is connected to the floor of the vehicle (not shown) via a well-known electric sliding mechanism 20 and an electric lifter mechanism 22. The seat back 16 is connected to the seat cushion 14 via a well-known electric reclining mechanism 24.

[0022] A component 32, which is a component of the harness clip misassembly prevention structure 30 according to this embodiment, is attached to the lower surface of the seat cushion 14. As shown in Figures 2 to 7, the component 32 is manufactured, for example, by resin injection molding, and is in the shape of a substantially elongated plate with the left-right direction as the longitudinal direction and the up-down direction as the thickness direction. This component 32 is attached to a frame (not shown) of the seat cushion 14 by means of claw fitting or the like.

[0023] A seat ECU 34, an electronic unit that stores the seat position, is mounted on the upper surface of the assembly target part 32. The motors (not shown) of the electric sliding mechanism 20, the electric lifting mechanism 22, and the electric reclining mechanism 24 are electrically connected to the seat ECU 34 via a first harness 36. As shown in Figures 4 and 5, a first clip 38 is attached to the first harness 36.

[0024] The first clip 38 is manufactured, for example, by resin injection molding and has an elastically deformable claw portion (reference numeral omitted). The first clip 38 is inserted from one side (here, the top side) of the part to be assembled 32 into a first assembly hole 40 (see Figure 7) formed at one longitudinal end (here, the left end) of the part to be assembled 32. The first assembly hole 40 penetrates the part to be assembled 32 in the vertical direction. The first clip 38 is assembled to the part to be assembled 32 by the claw portion catching on the edge of the hole in the first assembly hole 40. As a result, the first harness 36 is secured to the part to be assembled 32 via the first clip 38. The assembly of the first clip 38 is performed, for example, at a manufacturing plant for a vehicle seat 10.

[0025] The assembly part 32 has a second assembly hole 46 (see Figure 7) adjacent to the first assembly hole 40. This second assembly hole 46 is located behind the first assembly hole 40 and penetrates the assembly part 32 in the vertical direction. The area around the second assembly hole 46 in the assembly part 32 is a recess 32A that is recessed toward the other side (here, the bottom side) of the assembly part 32 when viewed from one side (here, the top side) of the assembly part 32. The area where the recess 32A is formed in the assembly part 32 is a protrusion 32B that is projected toward the other side (here, the bottom side) of the assembly part 32 when viewed from the other side (here, the bottom side) of the assembly part 32.

[0026] The second mounting hole 46 described above corresponds to the second clip 44. The second clip 44 is attached to the second harness 42, which is routed from the floor of the vehicle to the underside of the seat cushion 14. The second clip 44, together with the first clip 38 and the component to be assembled 32, constitutes the harness clip misassembly prevention structure 30 according to the present invention.

[0027] The second clip 44 is manufactured, for example, by resin injection molding and has an elastically deformable claw portion (reference numeral omitted). The second clip 44 is inserted into the second mounting hole 46 from the other side (in this case, the bottom side) of the part to be assembled 32. The second clip 44 is assembled to the part to be assembled 32 by the claw portion catching on the edge of the hole in the second mounting hole 46. As a result, the second harness 42 is secured to the part to be assembled 32 via the second clip 44. The assembly of the second clip 44 is carried out, for example, in a vehicle manufacturing plant.

[0028] Within the recess 32A of the component to be assembled 32, a pair of protrusions 48 are formed around the second assembly hole 46. The pair of protrusions 48 are positioned on opposite sides of each other via the second assembly hole 46 and protrude upward (to one side of the component to be assembled 32) from the bottom surface of the recess 32A. The pair of protrusions 48 are plate-shaped with their opposing directions being the thickness direction, and are trapezoidal when viewed from the thickness direction. These protrusions 48 correspond to the "misassembly prevention part" in the present invention.

[0029] In the vehicle seat 10 with the above configuration, a first harness 36 and a second harness 42 are routed to the seat cushion 14 of the seat body 12 on which the vehicle occupant sits. An assembly target component 32 is attached to the underside of the seat cushion 14. A first assembly hole 40 and a second assembly hole 46 are formed adjacent to each other on this assembly target component 32.

[0030] A first clip 38 attached to the first harness 36 is inserted into the first mounting hole 40 from above, and the first clip 38 is assembled to the component 32 to be assembled. A second clip 44 attached to the second harness 42 is inserted into the second mounting hole 46 from below, and the second clip 44 is assembled to the component 32 to be assembled. A pair of protrusions 48, which are mis-assembly prevention parts, are provided around the second mounting hole 46. The pair of protrusions 48 protrude upward from the component 32 to be assembled, so that the first clip 38 is not mis-assembled into the second mounting hole 46 from above.

[0031] Furthermore, in this embodiment, the area surrounding the second assembly hole 46 in the component 32 to be assembled is a recessed portion 32A that is recessed downward when viewed from above, making it even easier to prevent the first clip 38 from being incorrectly assembled into the second assembly hole 46. In addition, in this embodiment, a pair of protrusions 48 arranged on opposite sides of each other via the second assembly hole 46 serve as an incorrect assembly prevention portion, effectively preventing the first clip 38 from being incorrectly assembled into the second assembly hole 46. Moreover, the protrusions 48 constituting the incorrect assembly prevention portion also have the function of protecting the claw portion of the second clip 44 when the second clip 44 is inserted into the second assembly hole 46.

[0032] It should be noted that the misassembly prevention portion in the present invention is not limited to the pair of protrusions 48 described above. For example, as shown in the first modified example in Figure 8, a pair of transverse ribs 50 may be configured as the misassembly prevention portion, which are arranged on opposite sides of each other via the second assembly hole 46 and whose longitudinal direction is perpendicular to the direction in which they face each other (i.e., the direction perpendicular to the through-direction of the second assembly hole 46). The pair of transverse ribs 50 combine the mechanism of a reinforcing rib with the function of a misassembly prevention portion.

[0033] Furthermore, as shown in the second modified example in Figure 9, for example, a single projection 52 formed around the second assembly hole 46 may be configured to prevent misassembly. Also, as shown in the third modified example in Figure 10, for example, a pair of vertical ribs 54 that face each other via the second assembly hole 46 and extend in directions perpendicular to the direction of mutual opposition and the direction through which the second assembly hole 46 penetrates may be configured to prevent misassembly.

[0034] Furthermore, as shown in the fourth modified example in Figure 11, for example, an annular projection 56 protruding upward from the edge of the second assembly hole 46 may be configured to prevent misassembly. In the second to fourth modified examples described above, the area around the second assembly hole 46 in the assembly target part 32 is not a recess 32A, but is formed in a flat shape. In each of the above modified examples, the first clip 38 can be effectively prevented from being misassembled into the second assembly hole 46.

[0035] In the above embodiment, the present invention was described in the case where it is applied to a vehicle seat, but the present invention can also be applied to seats for vehicles other than vehicles (for example, aircraft and ships).

[0036] Furthermore, the present invention can be implemented with various modifications without departing from its spirit. Of course, the scope of the present invention is not limited to the embodiments described above. [Explanation of Symbols]
