[0029] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. Figure 1 This is a diagram of a vehicle seat 1 to which a seat cable module 100 according to an embodiment of the present invention is applied, as viewed from the Z direction.

[0030] like Figure 1 As shown, the seat cable module 100 of the present embodiment is applied to a vehicle seat 1 provided in a vehicle, for example.

[0031] In the following description, an orthogonal coordinate system (X, Y, Z) is used. The following figures are also represented using the same orthogonal coordinate system (X, Y, Z). The X-axis of this orthogonal coordinate system is set to correspond to the left-right direction of the vehicle having the vehicle seat 1, the Y-axis is set to correspond to the front-back direction of the vehicle, and the Z-axis is set to correspond to the up-down direction of the vehicle.

[0032] [Transportation seats]

[0033] A vehicle seat 1 includes a seat back (not shown) serving as a backrest for an occupant, a seat cushion (not shown) serving as a seating area for the occupant, and the aforementioned seat cable module 100. The vehicle seat 1 is provided with, for example, a reclining device (not shown). Therefore, when an occupant operates an operating lever (not shown) of the reclining device, the force is transmitted via the seat cable 2 to a release lever for releasing the seat back lock. The seat back lock is released, and the seat back is tilted.

[0034] [Seat]

[0035] The seat cushion (not shown) includes a seat frame 10 constituting the framework of the seating portion of the vehicle seat 1. The seat frame 10 is formed in a substantially rectangular frame shape and includes a pair of side frames 11, a front pipe 13, a rear pipe 14, and a load-bearing member 15.

[0036] The pair of side frames 11 are arranged to face each other in the X direction and constitute a part of the outer frame of the seat frame 10 .

[0037] The front pipe 13 is a portion that bridges the pair of side frames 11 , and is disposed in a portion of the side frame 11 that is located on the positive side in the Y direction relative to the center portion in the Y direction.

[0038] The rear pipe 14 connects the ends on the negative side in the Y direction of the pair of side frames 11 and constitutes a part of the outer frame of the seat frame 10 .

[0039] The load receiving member 15 receives the load when the occupant sits on the seat cushion, and is made of a flexible wire material, etc. The load receiving member 15 has a bridge portion 15A that bridges the pair of side frames 11 .

[0040] The bridge portion 15A is attached to a portion of the side frame 11 that is located closer to the - side in the Y direction than the center portion in the Y direction.

[0041] [Seat cable module]

[0042] Seat cable module 100 is configured to attach seat cable 2 of vehicle seat 1 and components connecting seat cable 2 to seat components. In this embodiment, seat cable module 100 is provided on the seat cushion. The seat cushion (seat frame 10) is one example of a "seat component" according to the present invention.

[0043] like Figure 1 and Figure 2 As shown, a seat cable module 100 is disposed between a pair of side frames 11 and mounted on the seat frame 10. In addition to the seat cable 2 described above, the seat cable module 100 further includes a connecting portion 110, a main body 120, a first retaining portion 130, and a second retaining portion 140. The connecting portion 110, the main body 120, the first retaining portion 130, and the second retaining portion 140 are included in the "cable retaining device" of the present invention.

[0044] The seat cables 2 are control cables used to operate the reclining mechanism of the vehicle seat 1 and the locking mechanism that secures the position of the seat surface of the vehicle seat 1. In this embodiment, the seat cables 2 include a first seat cable connected to the aforementioned operating lever and a second seat cable connected to the aforementioned release lever. Each seat cable 2 includes an inner cable and an outer housing through which the inner cable is inserted.

[0045] [Connection]

[0046] The connecting portion 110 is a cable connector that is interposed between the first seat cable and the second seat cable and connects the first seat cable and the second seat cable, and is mounted on the main body 120 .

[0047] The connecting portion 110 includes, for example, a joint housing and a joint piece accommodated in the joint housing. The joint piece is a portion that connects the ends of the inner cables of the seat cables 2 to each other.

[0048] By providing the coupling portion 110 in this manner, when the passenger operates the operating lever, the operating force input to the first seat cable is transmitted to the second seat cable via the coupling portion 110 , thereby driving the release lever.

[0049] [Main body]

[0050] The main body 120 is a plate-shaped resin member (e.g., polypropylene) and is positioned between the head tube 13 and the bridge portion 15A of the load-bearing member 15. The main body 120 has a length in the Y direction corresponding to the distance in the Y direction between the head tube 13 and the bridge portion 15A. The main body 120 is provided with a mounting portion 121 and an engaging portion 122. Alternatively, the main body 120 may have a length in the Y direction greater than the length corresponding to the aforementioned distance.

[0051] The mounting portion 121 is a portion to which the connecting portion 110 is mounted, and is disposed on the negative side of the head pipe 13 in the Y direction in the main body 120 when the seat cable module 100 is mounted on the seat frame 10 .

[0052] The engaging portion 122 is disposed on the negative end of the main body 120 at both ends (the first end and the second end) in the Y direction, and is located closer to the negative side in the Y direction than the mounting portion 121. The engaging portion 122 protrudes from the main body 120 toward the positive side in the Z direction and extends toward the positive side in the Y direction.

[0053] Thus, in the engaging portion 122 , a portion of the seat cable 2 can be arranged in a space protruding from the main body 120 and engaged therewith.

[0054] Furthermore, a first holding portion 130 is provided at an end portion of the main body 120 on the positive side in the Y direction, and a second holding portion 140 is provided at an end portion of the main body 120 on the negative side in the Y direction.

[0055] [First holding unit]

[0056] like Figure 3 As shown, the first holding portion 130 is configured to be able to hold the front pipe 13. The front pipe 13 corresponds to the "first seat frame" of the present invention.

[0057] Specifically, the first retaining portion 130 is configured to protrude from the main body 120 toward the positive side in the Z direction and extend toward the negative side in the Y direction. The first retaining portion 130 is arranged to contact a portion on the positive side in the Y direction and a portion on the positive side in the Z direction of the head pipe 13. The surface of the first retaining portion 130 that contacts the head pipe 13 on the positive side in the Z direction has a shape that follows the circumferential surface of the head pipe 13.

[0058] The main body 120 is disposed opposite to the Z-side portion of the head pipe 13. A portion 123 of the main body 120 that faces the head pipe 13 has a shape that follows the peripheral surface of the head pipe 13.

[0059] Therefore, the first holding portion 130 is attached to the head pipe 13 so that the main body 120 can be rotated with the first holding portion 130 as a fulcrum.

[0060] [Second holding unit]

[0061] like Figure 2 As shown, the second holding portion 140 is configured to hold the bridging portion 15A of the load receiving member 15 and includes a first wall portion 141, a second wall portion 142, a third wall portion 143, and an elastic portion 144. The bridging portion 15A corresponds to the "second seat frame" of the present invention.

[0062] The first wall portion 141 and the second wall portion 142 are portions located closer to the positive side in the Z direction than the bridge portion 15A (see also Figure 4A The first wall portion 141 and the second wall portion 142 protrude from the end portion of the main body portion 120 on the - side in the Y direction toward the - side in the Y direction, and are configured in a U-shape that opens toward the + side in the Y direction.

[0063] The first wall portion 141 is provided on the - side in the X direction of the end portion on the - side in the Y direction of the main body portion 120. The second wall portion 142 is provided on the + side in the X direction of the end portion on the - side in the Y direction of the main body portion 120. The first wall portion 141 and the second wall portion 142 have substantially the same shape.

[0064] The third wall portion 143 is located on the - side of the bridge portion 15A in the Z direction (see also Figure 4A ), and is provided to protrude from the - side end portion of the main body 120 in the Y direction toward the - side. The third wall portion 143 is provided at the center portion in the X direction of the - side end portion of the main body 120 in the Y direction. In other words, the first wall portion 141 and the second wall portion 142 are arranged so as to sandwich the third wall portion 143 in the X direction (first direction) in which the bridging portion 15A extends.

[0065] Moreover, if Figure 4A As shown, the Z-direction spacing D between the first and second walls 141, 142, and the third wall 143 is longer than the Z-direction length of the bridge portion 15A. Therefore, when the second holding member 140 is arranged so that the bridge portion 15A is sandwiched between the first and second walls 141, 142, and the third wall 143 in the Z-direction, a space is created between the first and second walls 141, 142, and the bridge portion 15A, allowing the bridge portion 15A to move relative to the second holding member 140 in the Z-direction.

[0066] For example, Figure 4B As shown, when an external force in the Z direction acts on the seat cable module 100 , the bridging portion 15A can move in the Z direction between the first wall portion 141 , the second wall portion 142 and the third wall portion 143 .

[0067] like Figure 2 As shown, the elastic portion 144 is an elastically deformable claw portion that extends from the ends of the first wall portion 141 and the second wall portion 142 on the - side in the Y direction toward the + side in the Y direction. In other words, the elastic portion 144 extends from the bottom portion of the U-shape of the first wall portion 141 and the second wall portion 142 toward the + side in the Y direction (the second direction orthogonal to the first direction). Figure 4A as well as Figure 5A As shown, the elastic portion 144 is provided so as to be located on the - side in the Z direction relative to the first wall portion 141 and the second wall portion 142 .

[0068] Specifically, when the second retaining portion 140 is arranged to retain the bridging portion 15A, the elastic portion 144 is configured to press the bridging portion 15A against the third wall portion 143. In other words, the elastic portion 144 urges the bridging portion 15A toward the third wall portion 143. As a result, the third wall portion 143 is arranged to support the bridging portion 15A on the side opposite to the first wall portion 141 and the second wall portion 142.

[0069] Therefore, the first wall portion 141 and the second wall portion 142 are arranged with a gap therebetween from the bridging portion 15A that allows the bridging portion 15A to move.

[0070] Furthermore, as described above, when an external force in the Z direction acts on the seat cable module 100, Figure 5B As shown, the elastic portion 144 is flexed and deformed, and its restoring force presses the bridging portion 15A toward the third wall portion 143. Therefore, a force to return to the position supported by the third wall portion 143 (the position indicated by the two-dot chain line) acts on the bridging portion 15A, thereby reducing vibration of the bridging portion 15A within the second retaining portion 140.

[0071] The elastic portion 144 also includes a restricting portion 144A. The restricting portion 144A protrudes from the substantially center portion of the elastic portion 144 in the Y direction toward the - side in the Z direction. When the bridging portion 15A is held by the second holding portion 140, the restricting portion 144A is positioned toward the - side in the Y direction relative to the bridging portion 15A.

[0072] Thus, the restricting portion 144A restricts the relative movement of the bridging portion 15A with respect to the elastic portion 144 in the Y direction.

[0073] The limiting portion 144A has an inclined surface that is inclined so as to be located on the + side in the Z direction as it approaches the side opposite to the holding position of the bridging portion 15A (the - side in the Y direction) from the vertex portion that protrudes most on the - side in the Z direction.

[0074] The inclined surface allows the bridge portion 15A to slide over the apex portion when the bridge portion 15A is held by the second holding portion 140 .

[0075] Furthermore, a predetermined gap is provided between the restricting portion 144A and the bridging portion 15A in the Y direction. In other words, the restricting portion 144A and the bridging portion 15A are arranged with a predetermined gap. This creates a space between the restricting portion 144A and the bridging portion 15A for relative movement of the bridging portion 15A in the Y direction relative to the second holding portion 140.

[0076] Thus, even if the bridging portion 15A relatively moves in the Y direction due to an external force, the movement is allowed by the prescribed interval. That is, in a case where an external force in the Y direction acts on the seat cable module 100, the bridging portion 15A is able to move in the Y direction.

[0077] [Effects of the seat cable module]

[0078] The effects of the present embodiment configured as described above are described. The seat cable module 100, for example, installs the linking portion 110 having the seat cable 2 linked thereto to the main body portion 120, and holds the front tube 13 by the first holding portion 130. Then, the main body portion 120 is rotated with the first holding portion 130 as a fulcrum, and the bridging portion 15A is held by the second holding portion 140. Thus, the seat cable module 100 is installed to the seat frame 10.

[0079] Thus, in the seat cable module 100, the seat cable 2 and the linking portion 110 can be easily installed to the seat frame 10 as a unit. Therefore, compared to a structure in which the seat cable and the linking portion are separately installed to the seat frame, efficiency of installation work can be achieved.

[0080] However, in a seat constituent member such as a seat cushion, an external force greater than an external force acting when an occupant is seated on the vehicle seat 1, that is, an external force beyond the range of normal use, sometimes acts. For example, it is a case where the occupant locally presses the seat cushion with knees or the like.

[0081] In such a case, a situation where the relative positional relationship of the seat frame 10 and the seat cable module 100 is shifted, and the seat frame 10 relatively moves with respect to the seat cable module 100, occurs.

[0082] For example, in a case of a structure in which the seat cable module is installed to the seat frame in a manner that the seat cable module is not movable, if an external force beyond the range of normal use acts on the seat constituent member, the positional relationship between the seat constituent member and the seat cable module does not change, and the installation portion of the seat cable module can be damaged.

[0083] In contrast, in the present embodiment, the second holding portion 140 has a space in which the bridging portion 15A relatively moves with respect to the second holding portion 140 in a state of being held by the second holding portion 140 when an external force acts on the main body portion 120 (refer to Figure 4A 、 Figure 4B 、 Figure 5A and Figure 5B ).

[0084] Thus, the second holding portion 140 can easily absorb relative movement of the bridging portion 15A caused by an external force, thereby preventing the seat cable module 100 (cable holding device) from being damaged by the external force.

[0085] Furthermore, the second retaining portion 140 includes the first wall portion 141 , the second wall portion 142 , and the third wall portion 143 . This allows the second retaining portion 140 to be easily configured to allow movement of the bridging portion 15A, thereby more effectively absorbing relative movement of the bridging portion 15A.

[0086] Furthermore, if there is any deviation in the installation position of the bridge portion 15A or the head pipe 13, the position of the second retaining portion 140 attached to the bridge portion 15A can be easily adjusted using the space within the second retaining portion 140. In other words, the space within the second retaining portion 140 can accommodate such deviation, making it easier to install the seat cable module 100.

[0087] In addition, since the first wall portion 141 and the second wall portion 142 are arranged at positions sandwiching the third wall portion 143 in the X direction, the bridging portion 15A is not sandwiched by the first wall portion 141 or the second wall portion 142 and the third wall portion 143 at the same position in the X direction in the Z direction.

[0088] If the bridge portion is sandwiched between the first wall portion, the second wall portion, and the third wall portion at the same position in the X direction, the force applied from the bridge portion is likely to concentrate on that position when the bridge portion vibrates within the second holding portion.

[0089] In contrast, in this embodiment, the bridging portion 15A is not sandwiched between the first wall portion 141 or the second wall portion 142 and the third wall portion 143 at the same position in the X direction. Therefore, when the bridging portion 15A vibrates within the second retaining portion 140, the positions at which the force from the bridging portion 15A is applied can be varied in the X direction. As a result, the force applied from the bridging portion 15A can be easily distributed among the first wall portion 141, the second wall portion 142, and the third wall portion 143.

[0090] In addition, since the elastic portion 144 urges the bridge portion 15A toward the third wall portion 143, it is possible to suppress vibration of the bridge portion 15A within the second holding portion 140 when the vehicle vibrates (see FIG. Figure 5A as well as Figure 5B As a result, the generation of vibration sound caused by the bridge portion 15A vibrating in the space within the second holding portion 140 and colliding with the wall can be suppressed.

[0091] Furthermore, since the elastic portion 144 is provided on each of the first wall portion 141 and the second wall portion 142, the bridging portion 15A can be biased at both the first wall portion 141 and the second wall portion 142. As a result, the positional relationship between the first wall portion 141 and the second wall portion 142 and the bridging portion 15A can be stabilized.

[0092] Furthermore, since the elastic portion 144 includes the restriction portion 144A, it is possible to prevent the bridging portion 15A from moving in the Y direction and coming off from the elastic portion 144 (the second holding portion 140 ).

[0093] Furthermore, the first retaining portion 130 is attached to the head pipe 13 so that the main body 120 can be rotated. Therefore, after the first retaining portion 130 is attached to the head pipe 13, the main body 120 can be rotated to easily align the position of the second retaining portion 140 with the bridge portion 15A, thereby facilitating the installation operation.

[0094] Furthermore, the connecting portion 110 is provided between the main body 120 , that is, between the first holding portion 130 and the second holding portion 140 . This eliminates the need to make the main body 120 larger than necessary, thereby contributing to miniaturization of the seat cable module 100 .

[0095] Furthermore, since the engaging portion 122 that engages with and holds the seat cable 2 is provided between the main body 120 , that is, between the first holding portion 130 and the second holding portion 140 , interference between the engaging portion 122 and any portion other than the head pipe 13 and the bridge portion 15A can be suppressed.

[0096] Furthermore, since the engaging portion 122 extends from the - side (one side) of the main body 120 in the Y direction toward the + side (the other side) in the Y direction, even if the seat cable 2 is detached from the engaging portion 122, the seat cable 2 is easily retained within the main body 120. As a result, it is possible to prevent the seat cable 2 from being positioned outside the range of the seat cable module 100 (cable retaining device).

[0097] Furthermore, in the above embodiment, the connection portion 110 is configured to be attachable to the main body 120 , but the present invention is not limited thereto, and the connection portion may be integrally configured with the main body.

[0098] In the above embodiment, the coupling portion 110 and the engaging portion 122 for holding the seat cable 2 are provided. However, the present invention is not limited thereto. As long as the seat cable is held at a portion other than the coupling portion and the engaging portion, the coupling portion and the engaging portion may not be provided.

[0099] Further, in the above-described embodiment, the elastic portion 144 is provided to both the first wall portion 141 and the second wall portion 142, but the present application is not limited thereto. For example, the elastic portion can be provided to only one of the first wall portion and the second wall portion, or can be provided to a portion other than the first wall portion and the second wall portion.

[0100] Further, in the above-described embodiment, the elastic portion 144 is provided to the second holding portion 140, but the present application is not limited thereto, and the elastic portion can not be provided to the second holding portion. However, from the viewpoint of suppressing the vibration sound of the second seat frame in the second holding portion, it is preferable that the elastic portion be provided to the second holding portion.

[0101] Further, in the above-described embodiment, the elastic portion 144 has the restriction portion 144A, but the present application is not limited thereto, and the elastic portion can not have the restriction portion.

[0102] Further, in the above-described embodiment, the first wall portion 141 and the second wall portion 142 are provided at positions sandwiching the third wall portion 143 in the X direction, but the present application is not limited thereto, and the first wall portion and the second wall portion can not be provided at positions sandwiching the third wall portion in the X direction.

[0103] Further, in the above-described embodiment, the second holding portion has the first wall portion and the second wall portion and the third wall portion, but the present application is not limited thereto, and can have a structure having either one of the first wall portion and the second wall portion and the third wall portion.

[0104] Further, in the above-described embodiment, the first holding portion is provided so as to be able to rotate the main body portion with the first holding portion as a fulcrum, but the present application is not limited thereto, and can not be provided so as to be able to rotate the main body portion.

[0105] Further, in the above-described embodiment, the front pipe 13 is exemplified as the first seat frame, but the present application is not limited thereto, and a seat frame other than the front pipe can be used as the first seat frame.

[0106] Further, in the above-described embodiment, the cross portion 15A is exemplified as the second seat frame, but the present application is not limited thereto, and a seat frame other than the cross portion can be used as the second seat frame.

[0107] Further, in the above-described embodiment, the seat cushion is exemplified as the seat constituent member, but the present application is not limited thereto, and a member other than the seat cushion, such as a seat back, can be used as the seat constituent member.

[0108] Further, in the above-described embodiment, the vehicle seat 1 is a seat mounted on a vehicle, but the present application is not limited thereto, and can be a seat mounted on a vehicle other than a vehicle.

[0109] The embodiments disclosed herein are to be considered in all respects as illustrative and non-restrictive.
