Description

holding device

[0001] The present disclosure relates to a holding device for a flexible filament member.

[0002] Japanese Patent Application Laid-Open Publication No. 2023-16228 discloses a holding device for attaching a wire member such as a cable to a vehicle seat. The holding device includes a main body that holds the wire member, a first holding part that is provided on the main body and holds a front pipe, and a second holding part that is provided on the main body and holds a rear pipe.

[0003] In the above-described retaining device, while the linear member is temporarily held in the main body, it is necessary to adjust the main body to an appropriate position via the first retaining portion and the second retaining portion according to the shape of the vehicle seat or the destination (application) of the linear member. This poses a problem in that the adjustment work of the retaining device is cumbersome. This makes it difficult to attach the linear member to the main body of the retaining device.

[0004] The present disclosure aims to solve the above-mentioned problems.

[0005] An aspect of the present disclosure is a holding device for holding a flexible linear member attached to a vehicle seat, comprising a base member and a plurality of holding members that are detachable from the base member and hold the linear member, and the attachment positions of the plurality of holding members relative to the base member can be changed.

[0006] According to the retaining device of the present disclosure, by appropriately attaching and detaching the retaining member to the base member, the position of the retaining member can be changed depending on the shape of the vehicle seat, thereby effectively retaining the linear member in a desired shape, which is highly versatile. Furthermore, by attaching the retaining member to the base portion after the linear member is retained by the retaining member, the workability of retaining the linear member is improved.

[0008] As shown in FIG. 1 , the retaining device 10 according to the first embodiment is used to retain a linear member 12 attached to a vehicle seat 100 (see FIG. 5 ). The linear member 12 is flexible. The linear member 12 is, for example, a cable, a harness, or a wire. Below, a case where a cable is used as the linear member 12 will be described. The cable electrically connects, for example, an electrical component attached to the vehicle seat 100 to a power source (battery) (not shown).

[0009] The holding device 10 includes a base member 14 and a plurality of holding members 16 .

[0010] The base member 14 is made of a resin material. However, the base member 14 is not limited to being made of a resin material. For example, the base member 14 may be made of a metal material.

[0011] The base member 14 has a first surface 141 formed in a plate shape facing the linear member 12, and a second surface 142 opposite the first surface 141. Each of the first surface 141 and the second surface 142 is a plane that is perpendicular to the thickness direction of the base member 14. Hereinafter, the direction perpendicular to the thickness direction of the base member 14 will be referred to as the "plane direction of the base member 14."

[0012] As shown in FIG. 2 , the base member 14 has a plurality of base pieces 18 that are detachable from one another. Below, a description will be given of a case where the base member 14 is composed of four base pieces 18. Note that the base member 14 is not limited to being composed of four base pieces 18. For example, the base member 14 may be composed of three or fewer base pieces 18, or may be composed of five or more base pieces 18. The plurality of base pieces 18 have substantially the same shape. Each of the plurality of base pieces 18 has a connecting portion 20 that allows them to be connected to one another. As shown in FIG. 3 , a single base member 14 is formed by connecting the plurality of base pieces 18 to one another.

[0013] The connecting portions 20 are provided on the edge of each base piece 18. Each connecting portion 20 has a plurality of connecting protrusions 201. Each of the plurality of connecting protrusions 201 protrudes from the edge of the base piece 18 in the surface direction of the base member 14. Each of the plurality of connecting protrusions 201 is spaced apart from one another along the edge of the base piece 18.

[0014] In two adjacently arranged base pieces 18, the connecting protrusions 201 of one base piece 18 and the connecting protrusions 201 of the other base piece 18 are arranged offset from each other along the edges of the base pieces 18. The two base pieces 18 are connected to each other by inserting the connecting protrusions 201 of one base piece 18 between the connecting protrusions 201 of the other base piece 18. The two connected base pieces 18 are formed flat.

[0015] The base member 14 has a plurality of mounting portions 22 for mounting the plurality of holding members 16. The mounting portions 22 are spaced apart from one another along the surface of the base member 14. Here, a direction perpendicular to the thickness direction of the base member 14 is defined as the length direction (direction of arrow A), and a direction perpendicular to the thickness direction of the base member 14 and perpendicular to the length direction is defined as the width direction (direction of arrow B). The mounting portions 22 are spaced apart from one another in the length direction and spaced apart from one another in the width direction. The mounting portions 22 are provided on each base piece 18. The mounting portions 22 are spaced apart from one another along the first surface 141 of the base member 14 (base piece 18). The mounting portions 22 are spaced apart from one another at equal intervals. Note that the mounting portions 22 are not limited to being spaced apart from one another at equal intervals. For example, the mounting portions 22 may be spaced apart from one another at unequal intervals. As shown in FIG. 3, in the first embodiment, each base piece 18 has twelve mounting portions 22 .

[0016] Each of the multiple mounting portions 22 has a mounting hole 24. Each mounting hole 24 opens to the first surface 141 and penetrates the base member 14 in the thickness direction (see FIG. 4A ). As shown in FIG. 4B , in a cross section perpendicular to the axial direction of the mounting hole 24 (a cross section along the thickness direction of the base member 14), the cross-sectional shape of each of the multiple mounting holes 24 is polygonal. Below, a case where the cross-sectional shape of each mounting hole 24 is hexagonal will be described. Note that the cross-sectional shape of each mounting hole 24 is not limited to a hexagonal shape. For example, the cross-sectional shape of each mounting hole 24 may be triangular, rectangular, or pentagonal.

[0017] As shown in FIG. 4A , the mounting portion 22 further has a recess 26. The recess 26 is recessed from the second surface 142 of the base member 14 in the thickness direction of the base member 14. The mounting hole 24 is provided at the center of the recess 26. As shown in FIG. 4B , when viewed from the thickness direction of the base member 14, the recess 26 is formed larger than the mounting hole 24 so as to surround the mounting hole 24. The cross-sectional shape of the recess 26 is polygonal corresponding to the mounting hole 24. Note that the cross-sectional shape of the recess 26 is not limited to being polygonal. For example, the cross-sectional shape of the recess 26 may be circular or rectangular.

[0018] 3, the base member 14 further has a plurality of fastening holes 28. The plurality of fastening holes 28 are provided at the corners of the base member 14. That is, a fastening hole 28 is provided in each of the four base pieces 18. When the base member 14 is attached to the vehicle seat 100, fasteners 30 are inserted into the fastening holes 28 and fastened to the vehicle seat 100 (see FIGS. 7A and 7B).

[0019] 1 , the plurality of holding members 16 are detachable from the base member 14 and hold the linear members 12. The attachment positions of the plurality of holding members 16 relative to the base member 14 are changeable. Each holding member 16 is detachable from each attachment portion 22 of the base member 14.

[0020] Each holding member 16 is made of a resin material. As shown in Figure 2, each holding member 16 includes a main body 32, a holding portion 34 capable of holding the linear member 12, and an insertion portion 36 attachable to the attachment portion 22.

[0021] 4A , the base end of the main body portion 32 abuts against the first surface 141 when the holding member 16 is attached to the base member 14. The holding portion 34 is provided at the tip of the main body portion 32. The holding portion 34 extends from the side surface of the main body portion 32 along the surface direction of the base member 14. The holding portion 34 has a tip that is farthest from the main body portion 32, and is provided with a claw portion 38 at the tip. The claw portion 38 protrudes from the tip of the holding portion 34 in a direction intersecting the extension direction of the holding portion 34. The claw portion 38 and the main body portion 32 face each other in the extension direction of the holding portion 34.

[0022] The insertion portion 36 protrudes from the base end of the main body 32. The insertion portion 36 is inserted into the mounting hole 24 of the base member 14. As shown in FIG. 4B , the cross-sectional shape of the insertion portion 36 is polygonal in a cross section perpendicular to the axial direction of the insertion portion 36. The cross-sectional shape of the insertion portion 36 is formed to be the same as the cross-sectional shape of the mounting hole 24. Below, a case will be described in which the cross-sectional shape of the insertion portion 36 is hexagonal, the same as the cross-sectional shape of each mounting hole 24. Note that the cross-sectional shape of the insertion portion 36 is not limited to a hexagonal shape. As long as it is the same as the cross-sectional shape of the mounting hole 24, the cross-sectional shape of the insertion portion 36 may be, for example, triangular, rectangular, or pentagonal.

[0023] When the insertion portions 36 are inserted into each mounting hole 24, relative rotation of the insertion portions 36 with respect to the mounting hole 24 is prevented. As shown in Figure 3, in a plan view seen from the thickness direction of the base member 14, the holding member 16 can be attached to the base member 14 with the insertion portions 36 positioned at a predetermined angle in the circumferential direction with respect to the mounting holes 24. Because the cross-sectional shapes of each mounting hole 24 and the insertion portions 36 are hexagonal, the holding member 16 can be positioned in the rotational direction with respect to the mounting holes 24 of the base member 14 in 60° increments around the insertion portions 36. In other words, the position of the holding member 16 can be adjusted by rotating it in 60° increments with respect to the mounting holes 24 of the base member 14.

[0024] 4A , when the insertion portion 36 is inserted into each mounting hole 24, the tip of the insertion portion 36 protrudes from the mounting hole 24 and is housed in the recess 26. The tip of the insertion portion 36 does not protrude from the second surface 142.

[0025] Each of the multiple holding members 16 further has an engaging portion 40 that can engage with the base member 14. The engaging portion 40 is provided on the insertion portion 36 of each holding member 16. The engaging portion 40 is provided on the outer peripheral surface of the tip of the insertion portion 36. The engaging portion 40 protrudes radially outward from the outer peripheral surface of the insertion portion 36. As shown in FIG. 4B , a pair of engaging portions 40 are provided. The pair of engaging portions 40 are spaced apart from each other along the circumferential direction of the insertion portion 36. The pair of engaging portions 40 are arranged on opposite sides of the central axis of the insertion portion 36.

[0026] When the insertion portion 36 is inserted into the mounting hole 24 of the base member 14, the pair of engagement portions 40 contact the inner circumferential surface of the mounting hole 24, thereby allowing elastic deformation radially inward. As shown in Fig. 4A, when the holding member 16 is attached to the mounting portion 22 of the base member 14, the pair of engagement portions 40 are exposed and housed within the recess 26 through the mounting hole 24. The pair of engagement portions 40 contact the inner wall of the recess 26 that is parallel to the second surface 142, thereby fixing the pair of engagement portions 40 in a state where they are prevented from coming off the base member 14 in the direction of the first surface 141.

[0027] With the holding member 16 attached to the attachment portion 22 of the base member 14, the linear member 12 is held between the first surface 141 of the base member 14 and the holding portion 34 of the holding member 16. The linear member 12 is also held between the main body portion 32 and the claw portion 38 of the holding member 16.

[0028] The engaging portion 40 is not limited to being provided in pairs on the outer circumferential surface of the insertion portion 36. For example, there may be one engaging portion 40, or three or more engaging portions 40. Furthermore, the engaging portion 40 may be formed in a ring shape along the outer circumferential surface of the insertion portion 36.

[0029] Note that the present invention is not limited to the case where the holding member 16 has the convex insertion portion 36 and the base member 14 has the concave mounting hole 24 into which the insertion portion 36 is inserted. For example, the insertion portion 36 may be formed on the base member 14 so as to protrude from the first surface 141 of the base member 14, and the mounting hole 24 may be provided in the holding member 16.

[0030] Next, a vehicle seat 100 to which the support device 10 is attached will be described as shown in FIG.

[0031] The vehicle seat 100 is installed in a vehicle such as a car, a ship, or an aircraft. The vehicle seat 100 has a seat cushion 102 and a seat back 104 connected to the rear of the seat cushion 102, and an occupant (not shown) sits on the seat cushion 102. The seat cushion 102 has a seat cushion frame 106. The seat back 104 has a seat back frame 108. The seat cushion frame 106 and the seat back frame 108 form a seat frame 109.

[0032] The seat cushion frame 106 is installed on a floor surface 101 of a vehicle (not shown) via slide rails 110. The seat cushion frame 106 includes a pair of left and right cushion side frames 106A, a front pipe 114, a rear pipe 116, and a pan frame 118.

[0033] The front pipe 114 is connected to front portions of the pair of cushion side frames 106A. The front pipe 114 extends in the left-right direction of the vehicle seat 100. The rear pipe 116 is connected to rear portions of the pair of cushion side frames 106A. The rear pipe 116 extends in the left-right direction of the vehicle seat 100. The front pipe 114 and the rear pipe 116 are arranged approximately parallel to each other. The pan frame 118 is formed in a plate shape and extends in the front-rear direction of the vehicle seat 100. The seat cushion 102 has a cushion pad (not shown). The front pipe 114, the rear pipe 116, and the pan frame 118 are all arranged below the cushion pad of the seat cushion 102.

[0034] The pan frame 118 connects the front pipe 114 and the rear pipe 116. The upper surface of the pan frame 118 faces the seat cushion pad. The lower surface of the pan frame 118 faces the floor 101. The pan frame 118 has a front end 118F, a rear end 118R, and an intermediate portion 118M between the front end 118F and the rear end 118R. As shown in FIG. 6 , the front end 118F is fixed to the upper portion of the front pipe 114 by a fixing member 120. An airbag AB is provided on the upper surface of the front end 118F. When an impact is applied during a vehicle collision, the airbag AB deploys and inflates near the legs of an occupant seated in the vehicle seat 100. The rear end 118R is fixed to the upper portion of the rear pipe 116 by the fixing member 120. The fixing member 120 is, for example, a bolt or a clip.

[0035] The intermediate portion 118M is disposed between the front pipe 114 and the rear pipe 116. The retaining device 10 is fixed to the intermediate portion 118M by a fastener 30. As shown in FIG. 7A , the retaining device 10 is attached to the lower surface of the intermediate portion 118M. As shown in FIG. 6 , when viewed in the thickness direction of the pan frame 118, the retaining device 10 is disposed at a position that does not overlap with the airbag AB attached to the pan frame 118. In other words, on the pan frame 118, the airbag AB and the retaining device 10 are disposed spaced apart in the fore-and-aft direction of the vehicle seat 100. Note that the retaining device 10 may also be attached to the upper surface of the intermediate portion 118M.

[0036] 7A , the pan frame 118 further includes frame grippers 124. The frame grippers 124 are provided on both left and right ends of the pan frame 118. Each pair of frame grippers 124 protrudes downward from the pan frame 118. When assembling the pan frame 118 to the seat frame 109, the frame grippers 124 can be grasped by a seat assembly robot (not shown) and automatically assembled to the seat frame 109.

[0037] Next, a case where the linear member 12 is attached to the vehicle seat 100 using the retaining device 10 will be described.

[0038] First, as shown in Fig. 1, a base member 14 is prepared by connecting a plurality of base pieces 18 to one another. The base member 14 is formed by connecting the plurality of base pieces 18 to one another so as to have a size that corresponds to the wiring layout, including the shape and length of the linear members 12, that corresponds to the vehicle seat 100. Here, a case where a substantially square-shaped base member 14 is formed from four base pieces 18 will be described. Also, a case where two holding members 16 are used will be described.

[0039] Next, the linear member 12 is placed on the first surface 141 of the base member 14 and bent to form a desired routing layout. Hereinafter, a case will be described in which the linear member 12 is held in the retention device 10 in a routing layout having a bent portion 123 in the center between the first line portion 121 and the second line portion 122 of the linear member 12, as shown in FIG. 3 . Hereinafter, the base piece 18 on the base member 14 where the first line portion 121 of the linear member 12 is placed will be referred to as the "first base piece 181," and the base piece 18 on which the second line portion 122 of the linear member 12 is placed will be referred to as the "second base piece 182." When the retention device 10 is attached to the vehicle seat 100, the first base piece 181 is attached to the front, and the second base piece 182 is attached to the rear (see FIG. 6 ). The direction in which the first base piece 181 is provided will be referred to as the front of the retention device 10, and the direction in which the second base piece 182 is provided will be referred to as the rear of the retention device 10. The first base piece 181 and the second base piece 182 are arranged offset in the front-rear direction of the holding device 10 and in the width direction perpendicular to the front-rear direction.

[0040] 3 , the first surface 141 of the first base piece 181 is provided with a first mark portion M1 indicative of the connection destination to which the first line portion 121 of the line member 12 is connected, near where the first line portion 121 of the line member 12 is held. The first surface 141 of the second base piece 182 is provided with a second mark portion M2 indicative of the connection destination to which the second line portion 122 of the line member 12 is connected, near where the second line portion 122 of the line member 12 is held. The first mark portion M1 and the second mark portion M2 may be formed in advance before the line member 12 is held on the base member 14, or may be formed after the line member 12 is held on the base member 14. The inscriptions on the first mark portion M1 and the second mark portion M2 are, for example, names or marks. When connecting the wire member 12 attached via the holding device 10 to an electrical component, etc., by checking the first mark portion M1 and the second mark portion M2, the first wire portion 121 and the second wire portion 122 of the wire member 12 can be connected to the desired electrical component, respectively.

[0041] Hereinafter, one of the two holding members 16 will be referred to as the "first holding member 161" and the other as the "second holding member 162." The insertion portion 36 of the first holding member 161 is inserted into the mounting hole 24 of the first base piece 181 so that the holding portion 34 of the first holding member 161 covers the first wire portion 121 of the linear member 12. At this time, the user can select an optimal mounting position for the first holding member 161 from the multiple mounting holes 24 in the first base piece 181 for holding the first wire portion 121 of the linear member 12 and attach the first holding member 161. As shown in FIG. 4A , by inserting the insertion portion 36 of the first holding member 161 into one of the multiple mounting holes 24, the engagement portion 40 engages with the recess 26, thereby preventing the first holding member 161 from coming off the base member 14. By inserting the insertion portion 36 into the mounting hole 24, the first holding member 161 is fixed in a state in which it is prevented from rotating relative to the base member 14, as shown in Fig. 4B. As shown in Fig. 4A, the first wire portion 121 of the filament member 12 is held between the holding portion 34 of the first holding member 161 and the first surface 141 of the base member 14.

[0042] As shown in FIG. 3 , the insertion portion 36 of the second holding member 162 is inserted into the mounting hole 24 of the second base piece 182 so that the holding portion 34 of the second holding member 162 covers the second wire portion 122 of the wire member 12. At this time, the user can select an optimal mounting position for the second holding member 162 from the multiple mounting holes 24 in the second base piece 182 for holding the second wire portion 122 of the wire member 12 and attach the second holding member 162. By inserting the insertion portion 36 of the second holding member 162 into one of the multiple mounting holes 24, the second holding member 162 is prevented from slipping out of the base member 14 and is fixed in a state where the second holding member 162 is prevented from rotating relative to the mounting hole 24. The second wire portion 122 of the wire member 12 is held between the holding portion 34 of the second holding member 162 and the first surface 141 of the base member 14. As a result, the filament member 12 is held on the first surface 141 of the base member 14 with a bent portion 123 in the intermediate portion between the first line portion 121 and the second line portion 122 of the filament member 12 .

[0043] In the plan view of the base member 14 shown in FIG. 3 , the first line portion 121 of the line member 12 is held so as to be approximately perpendicular to the extension direction of the holding portion 34 of the first holding member 161. The first line portion 121 of the line member 12 is held between the main body 32 and the claw portion 38 of the first holding member 161. This suppresses movement of the first line portion 121 of the line member 12 in the extension direction of the holding portion 34. The second line portion 122 of the line member 12 is held so as to be approximately perpendicular to the extension direction of the holding portion 34 of the second holding member 162. At this time, the second line portion 122 of the line member 12 is held between the main body 32 and the claw portion 38 of the second holding member 162. This suppresses movement of the second line portion 122 of the line member 12 in the extension direction of the holding portion 34.

[0044] Next, the support device 10 holding the wire member 12 is attached to the vehicle seat 100. As shown in FIG. 7A , the second surface 142 of the base member 14 of the support device 10 is faced to the middle portion 118M of the pan frame 118, and the fasteners 30 inserted into the middle portion 118M of the pan frame 118 are fastened to the fastening holes 28 (see FIG. 3 ) of the base member 14. This secures the support device 10 to the underside of the pan frame 118. The wire member 12 faces the opposite side of the pan frame 118. As a result, the support device 10 attaches the wire member 12 to the lower portion of the seat cushion 102 of the vehicle seat 100 in a desired shape (wiring layout), as shown in FIG. 5 . The first wire portion 121 and the second wire portion 122 of the wire member 12 are electrically connected to a power source, electrical components, or the like (not shown) by referring to the first mark portion M1 and the second mark portion M2.

[0045] The support device 10 is not limited to being attached to the vehicle seat 100 together with the linear members 12. For example, the linear members 12 held by the support device 10 may be removed from the base member 14 and attached to the pan frame 118. In this case, the plurality of support members 16 of the support device 10 include temporary support portions 42 (see FIG. 1 ).

[0046] The temporary holding portion 42 extends from the tip end of the main body portion 32 and is formed to be elastically deformable. With the linear member 12 held on the base member 14 by the temporary holding portion 42, the linear member 12 can be attached to the vehicle seat 100 and the temporary holding portion 42 can be elastically deformed to detach the linear member 12 from the temporary holding portion 42 and attach only the linear member 12 to the vehicle seat 100.

[0047] The first embodiment has the following advantages.

[0048] 1, the retention device 10 retains a flexible linear member 12 attached to a vehicle seat 100. The retention device 10 includes a base member 14 and a plurality of retention members 16 that are detachable from the base member 14 and retain the linear member 12. The plurality of retention members 16 (first retention member 161, second retention member 162) are provided so that their attachment positions relative to the base member 14 can be changed.

[0049] This retaining device 10 is highly versatile because the retaining member 16 can be attached and detached to and from the base member 14 as needed, thereby changing the position of the retaining member 16 depending on the shape of the vehicle seat 100 and effectively retaining the linear member 12 in a desired shape. Furthermore, by attaching the retaining member 16 to the base member 14 after the linear member 12 is retained by the retaining member 16, the workability of retaining the linear member 12 is improved.

[0050] 2, the base member 14 has a plurality of mounting holes 24 for mounting a plurality of holding members 16. Each of the plurality of holding members 16 has an engaging portion 40 that can engage with the base member 14 (see FIG. 4A).

[0051] According to this configuration, the engaging portion 40 of the holding member 16 engages with the base member 14 , so that the holding member 16 can be effectively attached to the base member 14 .

[0052] 4B , in a cross section perpendicular to the axial direction of the mounting hole 24, the cross-sectional shape of the mounting hole 24 and the cross-sectional shape of the holding member 16 inserted into the mounting hole 24 are both polygonal. With this configuration, rotation of the holding member 16 relative to the base member 14 can be effectively prevented.

[0053] 1 , each of the plurality of retaining members 16 includes a temporary retaining portion 42 that temporarily retains the linear member 12. With this configuration, with the linear member 12 held to the base member 14 by the temporary retaining portion 42, the retaining device 10 can be attached to the vehicle seat 100 and the linear member 12 can be removed from the temporary retaining portion 42.

[0054] 2, the base member 14 has a plurality of detachable base pieces 18. With this configuration, the shape of the base member 14 can be changed according to the shape of the vehicle seat 100.

[0055] As shown in FIG. 6 , when viewed in the thickness direction of the pan frame 118 , the support device 10 is disposed at a position where it does not overlap with the airbag AB attached to the pan frame 118 .

[0056] According to this configuration, when the airbag AB is activated and deployed, contact between the airbag AB and the retaining device 10 is effectively suppressed.

[0057] As shown in FIG. 8, a holding device 10A according to the second embodiment includes a base member 14A and a plurality of holding members 16A.

[0058] As shown in Figure 9, the base member 14A has multiple base pieces 18A that are detachable from one another. The multiple base pieces 18A are connected to one another to form a single base member 14A. The base member 14A has multiple mounting portions 22A for mounting the multiple holding members 16A. The multiple mounting portions 22A are provided on each base piece 18A. The multiple mounting portions 22A are arranged spaced apart from one another along the surface direction of the base member 14A.

[0059] The multiple mounting portions 22A are arranged spaced apart from one another along the length direction (direction of arrow A) of the base member 14A. The multiple mounting portions 22A include a first mounting portion 200 and a second mounting portion 202. The first mounting portion 200 and the second mounting portion 202 face each other with the linear member 12A between them when the linear member 12A is held by the multiple holding members 16A.

[0060] The first mounting portion 200 is disposed on one side of the linear member 12A. The first mounting portion 200 is disposed inward of one end of each base piece 18A in the width direction (direction of arrow B) of the base member 14A. The first mounting portion 200 has a plurality of first mounting grooves 204 disposed at equal intervals from one another. The plurality of first mounting grooves 204 are recessed toward one side in the width direction along the first surface 141 of the base member 14A.

[0061] The second mounting portion 202 is disposed on the other side of the linear member 12A. The second mounting portion 202 is disposed more inward than the other end of each base piece 18A in the width direction of the base member 14A. In each base piece 18A, the first mounting portion 200 and the second mounting portion 202 are parallel to each other in the width direction. The second mounting portion 202 has a plurality of second mounting grooves 206 disposed at equal intervals from each other. The second mounting grooves 206 are recessed toward the other side in the width direction along the first surface 141 of the base member 14A. Each of the first mounting grooves 204 and each of the second mounting grooves 206 are disposed offset from each other in the front-rear direction of the base member 14A. That is, each of the first mounting grooves 204 and each of the second mounting grooves 206 are disposed alternately in the front-rear direction of the base member 14A. Each of the plurality of first mounting grooves 204 and each of the plurality of second mounting grooves 206 may be disposed at the same position in the front-rear direction of the base member 14A.

[0062] The first mounting portion 200 and the second mounting portion 202 are not limited to being arranged side by side in the width direction of the base member 14A (base piece 18A). For example, the first mounting portion 200 and the second mounting portion 202 may be arranged side by side in the front-to-rear direction of the base member 14A (base piece 18A). Below, a case will be described in which the first mounting portion 200 has four first mounting grooves 204 and the second mounting portion 202 has four second mounting grooves 206.

[0063] The plurality of holding members 16A are detachably attached to the plurality of mounting portions 22A. The plurality of holding members 16A hold the linear members 12A. The plurality of holding members 16A are attached to the first mounting portion 200 and the second mounting portion 202, respectively. The plurality of holding members 16A include a plurality of first holding members 211 attached to the plurality of first mounting portions 200 and a plurality of second holding members 212 attached to the plurality of second mounting portions 202. Each of the plurality of first holding members 211 and second holding members 212 is formed, for example, by bending a wire rod made of a metal material.

[0064] Each of the plurality of first holding members 211 is attached to a corresponding one of the plurality of first mounting grooves 204. Each of the first holding members 211 is formed so as to be engageable with the linear member 12A. As shown in FIG. 11A , each of the first holding members 211 includes a first main body portion 214 and a first holding portion 216. The attachment position of each of the plurality of first holding members 211 relative to the first mounting groove 204 of the base member 14A is changeable (see FIG. 10 ).

[0065] The base end of the first main body portion 214 is formed in a straight line and is attached to each of the first attachment grooves 204. As shown in Fig. 10, by attaching each of the plurality of first holding members 211 to each of the plurality of first attachment grooves 204, the plurality of first holding members 211 are arranged at equal intervals from one another.

[0066] 11A , the first holding portion 216 is provided at the tip of the first main body portion 214. The first holding portion 216 is disposed to protrude from the first attachment portion 200 in the direction of the second attachment portion 202. Each of the first holding portions 216 has a first protrusion 218 protruding from the base member 14A.

[0067] The first protrusion 218 protrudes from the tip of the first main body 214 in a direction approximately perpendicular to the extension direction of the first main body 214. The first protrusion 218 protrudes in a direction away from the first surface 141 of the base member 14A. The first protrusion 218 is elastically deformable with respect to the tip of the first main body 214. The first protrusion 218 has a first portion 220A, a second portion 220B, and a third portion 220C. The first portion 220A extends obliquely from the tip of the first main body 214 toward the tip of the first main body 214. The inclination angle θ1 of the first portion 220A with respect to the extension direction of the first main body 214 is approximately 120° to 150°. The second portion 220B extends from the tip of the first portion 220A in a direction away from the first surface 141. The extension direction of the second portion 220B is approximately parallel to the thickness direction of the base member 14A. The inclination angle θ2 of the second portion 220B with respect to the extension direction of the first main body portion 214 is approximately 80° to 100°. The third portion 220C extends obliquely from the end of the second portion 220B toward the base end of the first main body portion 214. The inclination angle θ3 of the third portion 220C with respect to the extension direction of the second portion 220B is approximately 120° to 150°.

[0068] The first protrusions 218 protrude in the same direction relative to the first surface 141 of the base member 14A. The first protrusions 218 protrude to the same height relative to the first surface 141.

[0069] As shown in FIG. 10 , each of the plurality of second holding members 212 is attached to a corresponding one of the plurality of second mounting grooves 206. Each of the second holding members 212 is formed so that the linear member 12A can be engaged therewith. As shown in FIG. 11A , each of the second holding members 212 includes a second main body portion 224 and a second holding portion 226. The attachment position of each of the plurality of second holding members 212 relative to the second mounting groove 206 of the base member 14A can be changed (see FIG. 10 ). Each of the plurality of second holding members 212 is formed in the same shape as each of the plurality of first holding members 211. Note that each of the plurality of second holding members 212 and each of the plurality of first holding members 211 may have a different shape.

[0070] The base end of the second main body portion 224 is formed linearly and is attached to each of the second mounting grooves 206. By attaching each of the second holding members 212 to each of the second mounting grooves 206, the second holding members 212 are arranged at equal intervals from one another, as shown in FIG. 10 . Each of the second holding members 212 and each of the first holding members 211 are arranged offset from one another in the front-to-rear direction (the direction of arrow A) of the base member 14A. That is, each of the first holding members 211 and each of the second holding members 212 are arranged alternately in the front-to-rear direction of the base member 14A. Note that the arrangement is not limited to the case where each of the second holding members 212 and each of the first holding members 211 are arranged offset from one another in the front-to-rear direction of the base member 14A. For example, each of the second holding members 212 and each of the first holding members 211 may be arranged at the same position in the front-to-rear direction of the base member 14A.

[0071] The second holding portion 226 is provided at the tip of the second main body portion 224. The second holding portion 226 is disposed to protrude from the second attachment portion 202 in the direction of the first attachment portion 200. Each second holding portion 226 has a second protrusion 228 protruding from the base member 14A.

[0072] 11A , the second protrusion 228 protrudes from the tip of the second main body 224 in a direction approximately perpendicular to the extension direction of the second main body 224. The second protrusion 228 protrudes in a direction away from the first surface 141 of the base member 14A. The second protrusion 228 is elastically deformable with respect to the tip of the second main body 224. The second protrusion 228 has a first portion 220A, a second portion 220B, and a third portion 220C. The first portion 220A, the second portion 220B, and the third portion 220C of the second protrusion 228 have the same shapes as the first portion 220A, the second portion 220B, and the third portion 220C of the first protrusion 218 and are arranged symmetrically. Therefore, the same reference numerals are used and detailed description thereof will be omitted.

[0073] The second protrusions 228 protrude in the same direction relative to the first surface 141 of the base member 14A. The second protrusions 228 protrude to the same height relative to the first surface 141.

[0074] The first protrusions 218 of each first holding member 211 and the second protrusions 228 of each second holding member 212 face each other. The height of each first protrusion 218 from the first surface 141 of the base member 14A is approximately the same as the height of each second protrusion 228 from the first surface 141. A linear member 12A is held between the first protrusions 218 (first holding portions 216) of the multiple first holding members 211 and the second protrusions 228 (second holding portions 226) of the multiple second holding members 212. The first protrusions 218 and the second protrusions 228 are elastically deformable in directions away from each other. As shown in FIG. 12A , by inserting the linear member 12A between the first protrusions 218 and the second protrusions 228, the linear member 12A pushes the first protrusions 218 and the second protrusions 228 in directions away from each other, causing elastic deformation (see the two-dot chain line). As shown in FIG. 11A, the linear member 12A is held at a position facing the first portion 220A of the first protruding portion 218 and the first portion 220A of the second protruding portion 228.

[0075] When the linear member 12A is held between the plurality of first holding members 211 and the plurality of second holding members 212, a distance C between the first protrusion 218 and the second protrusion 228 in a direction perpendicular to the linear member 12A is smaller than a diameter D (outer diameter) of the linear member 12A. The distance C is the minimum distance between the second portion 220B of the first protrusion 218 and the second portion 220B of the second protrusion 228. In other words, movement of the linear member 12A in the direction of the third portion 220C via the space between the second portion 220B of the first protrusion 218 and the second portion 220B of the second protrusion 228 is suppressed.

[0076] 11B, the wire member 12A includes a wire member main body 230 and a gripping portion 232 for gripping by an assembly robot R (see FIG. 12A). The wire member main body 230 is flexible. The wire member main body 230 includes an internal conductive member (not shown). As shown in FIG. 12A, the assembly robot R includes a robot main body R1 and a pair of openable and closable arms R2 provided below the robot main body R1.

[0077] 11B, the gripping portion 232 is attached to the outer periphery of the linear member main body 230. The gripping portion 232 protrudes radially outward from the outer periphery of the linear member main body 230.

[0078] The gripping portion 232 covers the outer periphery of the linear member main body 230. The gripping portion 232 is provided at a predetermined position in the extension direction of the linear member main body 230 (see FIG. 9 ). The gripping portion 232 includes an outer member 23A and an inner member 23B provided inside the outer member 23A. The outer member 23A is formed in a cylindrical shape from a metal material. In a cross section perpendicular to the axial direction of the linear member main body 230, the cross section of the outer member 23A is hexagonal. As shown in FIG. 12A , the outer member 23A of the gripping portion 232 is gripped by a pair of arms R2 of the assembly robot R. Note that the cross section of the outer member 23A is not limited to a hexagonal shape. For example, the cross section of the outer member 23A may be any polygonal shape that can be gripped by the arms R2 of the assembly robot R. As shown in FIG. 11B, the inner member 23B is made of a resin material and is provided between the outer member 23A and the outer periphery of the linear member main body 230.

[0079] As shown in FIG. 10, the base member 14A further includes a hole 234.

[0080] The hole 234 is provided adjacent to the mounting portion 22A. The hole 234 penetrates the base member 14A in the thickness direction. When the linear member 12A is held by the multiple holding members 16A, the hole 234 is provided in a region F facing the gripping portion 232 of the linear member 12A. The hole 234 is provided in the center of the base member 14A in the front-rear direction. The hole 234 separates the center of the mounting portion 22A in the front-rear direction. When the assembly robot R attaches the linear member 12A to the holding device 10A, a pair of arm portions R2 holding the gripping portions 232 are inserted into the hole 234.

[0081] Next, the case where the linear member 12A is held by the holding device 10A will be described.

[0082] First, as shown in Fig. 9, a base member 14A is prepared by connecting a plurality of base pieces 18A to each other. Here, a case will be described in which a substantially square-shaped base member 14A is constructed from four base pieces 18A, and the first line portion 121 of the filament member 12A is held by the first base piece 181A and the second line portion 122 of the filament member 12A is held by the second base piece 182A.

[0083] 12A, the arm R2 of the assembly robot R grips the first gripping portion 232A provided on the first wire portion 121 of the filament member 12A and transfers the first wire portion 121 of the filament member 12A to the first base piece 181A. The arm R2 is moved toward the hole 234 of the base member 14A, and while still gripping the first gripping portion 232A, the arm R2 is inserted into the hole 234 (see FIG. 12B).

[0084] When the first gripping portion 232A of the filamentary member 12A is accommodated in the hole 234 of the first base piece 181A and the filamentary member main body 230 comes into contact with the third portions 220C of the plurality of first protrusions 218 and the second protrusions 228, the filamentary member 12A moves along the third portions 220C toward the base member 14A, causing the third portions 220C of the first protrusions 218 and the third portions 220C of the second protrusions 228 to be pushed apart in directions away from each other and elastically deformed (see the dotted line shape in Figure 12A). After the filament member 12A moves toward the base member 14A and passes between the second portions 220B of the first protruding portion 218 and the second protruding portion 228, which are spaced apart from each other, the filament member 12A is held between the first portion 220A of the first protruding portion 218 and the first portion 220A of the second protruding portion 228. The first protruding portions 218 of the plurality of first holding members 211 and the second protruding portions 228 of the plurality of second holding members 212 hold the filament member main body 230 of the filament member 12A to the base member 14A. The plurality of first holding members 211 and second holding members 212 prevent the filament member 12A from moving in a direction away from the first surface 141 of the base member 14A. In the front-to-rear direction of the base member 14A, the first line portion 121 of the linear member 12A contacts the first surface 141 of the base member 14A. The first line portion 121 of the linear member 12A is held along the first surface 141 of the base member 14A by the first holding member 211 and the second holding member 212 attached to the first base piece 181A and the first surface 141 of the first base piece 181A. The first line portion 121 of the linear member 12A is held by the first base piece 181A (base member 14A) along the extension direction of the attachment portion 22A of the first base piece 181A.

[0085] As shown in Figure 9, the arm portion R2 of the assembly robot R grasps the second gripping portion 232B provided on the second line portion 122 of the filamentary member 12A, and while grasping the second gripping portion 232B, the arm portion R2 is inserted into the hole portion 234 of the second base piece 182A.

[0086] The second gripping portion 232B of the filamentary member 12A is received in the hole 234 of the second base piece 182A, and the filamentary member main body 230 comes into contact with the plurality of first protrusions 218 and second protrusions 228, causing the first protrusions 218 and the second protrusions 228 to elastically deform in a direction away from each other. After the filamentary member 12A moves toward the base member 14A through the gap between the first protrusions 218 and the second protrusions 228, the filamentary member main body 230 of the filamentary member 12A is held between the plurality of first holding members 211 and the plurality of second holding members 212 of the second base piece 182A. The second filamentary member 122 is held by the first holding members 211 and second holding members 212 attached to the second base piece 182A and the first surface 141 of the second base piece 182A, with its movement in a direction away from the base member 14A being restricted. The second line portion 122 of the line member 12A is held by the second base piece 182A (base member 14) along the extending direction of the attachment portion 22A of the second base piece 182A.

[0087] As a result, the line member 12A is held by the base member 14A of the retaining device 10A in a wiring layout having a bent portion 123 in the center between the first line portion 121 and the second line portion 122 of the line member 12A. The method of attaching the retaining device 10A holding the line member 12A to the vehicle seat 100 is the same as that of the retaining device 10 of the first embodiment described above, and therefore will not be described here.

[0088] The second embodiment has the following advantages.

[0089] As shown in Figure 9, the holding device 10A includes a linear member 12A, which includes a linear member main body 230 and a gripping portion 232 attached to the outer periphery of the linear member main body 230 and adapted to be gripped by an assembly robot R.

[0090] According to this configuration, the assembly robot R can grasp the gripping portion 232, thereby automating the attachment of the linear member 12A to the holding device 10A.

[0091] As shown in Figure 10, in the base member 14A, a hole portion 234 is formed in an area F facing the gripping portion 232 when the filamentary member 12A is held by the multiple holding members 16A, which penetrates the base member 14A in the thickness direction.

[0092] According to this configuration, the base member 14A is provided with the hole 234, so that contact between the assembly robot R gripping the gripping portion 232 and the base member 14A is effectively avoided.

[0093] 11A , each of the plurality of holding members 16A (first holding member 211, second holding member 212) has a plurality of first holding portions 216 and a plurality of second holding portions 226. The plurality of first holding portions 216 and the plurality of second holding portions 226 each have a plurality of protrusions (first protrusions 218 and second protrusions 228) that are engageable with the linear member 12A and protrude from the base member 14A. The plurality of first protrusions 218 and the plurality of second protrusions 228 protrude in the same direction from the base member 14A.

[0094] According to this configuration, the first protrusion 218 and the plurality of second protrusions 228 can effectively suppress movement of the linear member 12A.

[0095] A distance C between the first protrusion 218 and the second protrusion 228 facing each other with the linear member 12A therebetween is smaller than a diameter D of the linear member 12A.

[0096] According to this configuration, the linear member 12A is prevented from coming off from between the first protruding portion 218 and the second protruding portion 228, and movement of the linear member 12A can be effectively prevented.

[0097] As shown in FIG. 13, a holding device 10B according to the first modification includes a base member 14B and a plurality of holding members 16B that hold linear members 12B.

[0098] The base member 14B has a plurality of attachment portions 22 for attaching a plurality of holding members 16B. The plurality of attachment portions 22 include a first attachment portion 200 and a second attachment portion 202. The first attachment portion 200 and the second attachment portion 202 face each other with the linear member 12B therebetween when the linear member 12B is held by the plurality of holding members 16B.

[0099] The plurality of holding members 16B are detachably attached to the plurality of mounting portions 22. The plurality of holding members 16B are attached to the first mounting portion 200 and the second mounting portion 202, respectively. Each of the plurality of holding members 16B has a plurality of holding portions 34. The plurality of holding members 16B includes a plurality of first holding members 211B attached to the plurality of first mounting portions 200 and a plurality of second holding members 212B attached to the plurality of second mounting portions 202.

[0100] The multiple first holding members 211B include first body portions 214a to 214d, each having a different length. First body portion 214a is the shortest, followed by first body portion 214b, first body portion 214c, and first body portion 214d, in that order. The multiple first holding members 211B further include first protrusions 218 provided at the tips of the first body portions 214a to 214d. The second holding member 212B includes second body portions 224a to 224d, each having a different length. Second body portion 224a is the longest, followed by second body portion 224b, second body portion 224c, and second body portion 224d, in that order. The multiple second holding members 212B further include second protrusions 228 provided at the tips of the second body portions 224a to 224d.

[0101] Next, a case where the linear member 12B is held by the holding device 10B will be described. Here, the first linear portion 121 of the linear member 12B is held at one widthwise end of the base member 14B, and the second linear portion 122 of the linear member 12B is held at the other widthwise end of the base member 14B. In addition, the linear member 12B is held in a shape (wiring layout) having a bent portion 123 in the center.

[0102] First, a holding device 10B for mounting the linear member 12B is prepared.

[0103] Among the multiple holding members 211B, the holding member 211B having the shortest first body portion 214a (hereinafter referred to as the first holding member 211B) is attached to the first mounting portion 200 closest to the front end 14F of the base member 14B among the multiple first mounting portions 200. The first protrusion 218 of the first holding member 211B is positioned closer to one widthwise end of the base member 14B than the widthwise center. The multiple first holding members 211B are attached to the first mounting portions 200 in the order of first body portion 214b, first body portion 214c, and first body portion 214d from the front end 14F to the rear end 14R of the base member 14B. In other words, among the multiple first holding members 211B, the first holding member 211B positioned closest to the rear end 14R of the base member 14B has the longest length.

[0104] In a plan view seen from the thickness direction of the base member 14B, the positions of the plurality of first holding portions 216 are arranged so as to follow the wiring layout of the line members 12B.

[0105] Among the multiple holding members 212B, the holding member 212B having the longest second main body portion 224a (hereinafter referred to as the second holding member 212B) is attached to the second mounting portion 202 closest to the front end 14F of the base member 14B among the multiple second mounting portions 202. The second protrusion 228 of the second holding member 212B is positioned closer to one widthwise end of the base member 14B than the widthwise center of the base member 14B. The multiple second holding members 212B are attached to the second mounting portions 202 in the order of second main body portion 224b, second main body portion 224c, and second main body portion 224d from the front end 14F toward the rear end 14R of the base member 14B. In other words, among the multiple second holding members 212B, the second holding member 212B positioned closest to the rear end 14R of the base member 14B has the shortest length.

[0106] In a plan view seen from the thickness direction of the base member 14B, the positions of the plurality of second holding portions 226 are arranged so as to follow the wiring layout of the line members 12B.

[0107] When the assembly robot R (see FIG. 12A ) attaches the linear member 12B to the holding device 10B, the linear member 12B is inserted between the plurality of first holding members 211B and the plurality of second holding members 212B, whereby the linear member main body 230 of the linear member 12B is held by the first protrusions 218 of the plurality of first holding members 211B and the second protrusions 228 of the plurality of second holding members 212B. The first line portion 121 of the linear member 12B is held near the front end 14F of the base member 14, and the second line portion 122 of the linear member 12B is held near the rear end 14R of the base member 14.

[0108] The first modified example has the following effects.

[0109] Depending on the wiring layout of the line members 12B, each of the plurality of first holding members 211B and second holding members 212B having different shapes can be attached to the base member 14B as appropriate, thereby enabling the wiring layout of the line members 12B to be set more effectively.

[0110] As shown in Figure 14, the holding device 10C according to the second modification includes a base member 14C and a plurality of holding members 16C. The base member 14C includes a first mounting region F1 to which a linear member 12C is attached and a second mounting region F2 to which an electrical component E is attached. The first mounting region F1 and the second mounting region F2 are adjacent to each other. The base member 14C includes a wall portion 300 between the first mounting region F1 and the second mounting region F2. The wall portion 300 is provided on a first surface 141 of the base member 14C and is substantially perpendicular to the base member 14C.

[0111] The first attachment region F1 includes a plurality of attachment portions 22C and a plurality of holding members 16C. Each of the plurality of holding members 16C has a housing portion 302 capable of housing and holding a respective one of the linear members 12C. Each housing portion 302 corresponds to the cross-sectional shape of the linear member 12C and is generally annular with a partial opening. The linear member 12C is inserted into the housing portion 302 through the opening, thereby holding the linear member 12C in the holding member 16C. The linear member 12C includes a first linear member 12C1, a second linear member 12C2, and a third linear member 12C3.

[0112] Each of the plurality of attachment portions 22C is an attachment hole. The plurality of holding members 16C includes a first holding member 211C that holds the first line member 12C1, a second holding member 212C that holds the second line member 12C2, and a third holding member 213C that holds the third line member 12C3.

[0113] Each of the first holding member 211C, the second holding member 212C, and the third holding member 213C is detachably attached to a plurality of attachment portions 22C in the first attachment region F1 of the base member 14C.

[0114] As shown in FIG. 15 , the multiple holding members 16C further include a fourth holding member 214C attached to the wall 300. The fourth holding member 214C is detachably attached to multiple attachment portions 22C provided on the wall 300. The fourth holding member 214C is disposed to protrude from the wall 300 toward the first attachment region F1. The fourth holding member 214C includes a first holding portion 216C that holds the first wire member 12C1 and a second holding portion 226C that holds the second wire member 12C2. The first holding portion 216C and the second holding portion 226C are aligned parallel to each other along the wall 300. The first holding portion 216C and the second holding portion 226C face each other in the thickness direction of the base member 14C. Therefore, the first holding portion 216C and the second holding portion 226C overlap when viewed in the thickness direction of the base member 14C. The second wire portion 122 of the first wire member 12C1 is accommodated and held in the accommodation portion 302 of the first holding portion 216C. The second wire portion 122 of the second wire member 12C2 is accommodated and held in the accommodation portion 302 of the second holding portion 226C (see FIG. 14).

[0115] As shown in FIG. 14 , an electrical component E used in the vehicle seat 100 is attached to the second attachment region F2.

The opening 306 is formed larger than the attachment hole 24. The air duct 308 is connected to an air supply pipe (not shown) through the opening 306 of the base member 14C. The air duct 308 can be efficiently inserted through the opening 306.

[0116] The wall portion 300 separates a first mounting area F1 in which the linear member 12C is held from a second mounting area F2 in which the blower 304 is disposed.

[0117] The second modified example has the following effects.

[0118] As shown in FIG. 15 , a fourth retaining member 214C for holding the linear member 12C can be attached using a wall portion 300 provided on the base member 14C. By arranging the first retaining portion 216C and the second retaining portion 226C facing each other in the thickness direction of the base member 14C, the space in the retaining device 10C can be effectively utilized. This allows for effective use of the space below the vehicle seat 100 to which the retaining device 10C is attached. Furthermore, since the fourth retaining member 214C can be positioned at a different position from the first retaining member 211C, the second retaining member 212C, and the third retaining member 213C provided on the first surface 141 of the base member 14C, the linear member 12C can be more effectively held. The wall portion 300 effectively protects the linear member 12C.

[0119] As shown in FIG. 16A , a holding device 10D according to the third modified example includes a base member 14D and a plurality of holding members 16D. The base member 14D includes a base portion 400 to which the plurality of holding members 16D are detachably attached, and a peripheral wall portion 402 extending from the outer edge of the base portion 400. The outer edge of the base portion 400 is surrounded by the peripheral wall portion 402. The upper portion of the base member 14D is open. The upper end of the peripheral wall portion 402 has an engaging protrusion 404. The engaging protrusion 404 protrudes from the upper end of the peripheral wall portion 402. The lower end of the peripheral wall portion 402 has an engaged portion 406. The engaged portion 406 is recessed from the lower end of the peripheral wall portion 402. A linear member 12D is attached to and held by the base portion 400 by the plurality of holding members 16D.

[0120] The holding device 10D is attached to the vehicle seat 100 in combination with an electrical unit 408 that houses electrical components E and a holding unit 410 that holds another wire member 12H such as a harness.

[0121] The electrical unit 408 includes a first housing 4081 and an electrical component E housed inside the first housing 4081. The first housing 4081 includes a base portion 4082 and a peripheral wall portion 4083 standing upright from the outer edge of the base portion 4082, and has the same shape as the base member 14D of the support device 10D. The electrical component E is, for example, an electrical component used in the vehicle seat 100. The electrical component E is the blower 304 that blows air to the vehicle seat 100. Note that the electrical component E is not limited to the blower 304. The electrical component E is fixed to the base portion 4082.

[0122] The holding unit 410 includes a second housing 4101 and a wire member 12H housed and held inside the second housing 4101. The second housing 4101 includes a base portion 4102 and a peripheral wall portion 4103 extending from the outer edge of the base portion 4102, and has the same shape as the base member 14D of the holding device 10D and the first housing 4081 of the electrical unit 408. The wire member 12H is, for example, a harness for supplying electrical signals to the electrical components E of the vehicle seat 100. However, the wire member 12H is not limited to a harness. The wire member 12H is fixed to the base portion 4102 by a plurality of holding members 16D.

[0123] 16A , the holding device 10D, the electrical unit 408, and the holding unit 410 can be stacked one on top of the other in the vertical direction. The electrical unit 408 is stacked on top of the holding device 10D, and the engaging protrusions 404 of the holding device 10D are engaged with the engaged portions 406 of the electrical unit 408. The holding unit 410 is stacked on top of the electrical unit 408, and the engaging protrusions 404 of the first housing 4081 of the electrical unit 408 are engaged with the engaged portions 406 of the second housing 4101 of the holding unit 410. Note that the stacking order of the holding device 10D, the electrical unit 408, and the holding unit 410 is not limited to the order of the holding device 10D, the electrical unit 408, and the holding unit 410 from bottom to top. For example, as shown in FIG. 16B, the electrical unit 408, the holding device 10D, and the holding unit 410 may be stacked in this order from bottom to top, or as shown in FIG. 16C, the holding unit 410, the holding device 10D, and the electrical unit 408 may be stacked in this order from bottom to top.

[0124] The third modified example has the following effects.

[0125] 16A , the degree of freedom in layout can be effectively improved by stacking the support device 10D in the vertical direction together with the electrical unit 408 and the support unit 410. Since the support device 10D can be efficiently stored in a storage location before being assembled to the vehicle seat 100, space can be saved.

[0126] In addition to the above disclosure, the following additional notes are disclosed.

[0127] (Supplementary Note 1) A retention device (10, 10A, 10B, 10C, 10D) retains a flexible linear member (12, 12A, 12B, 12C, 12D) attached to a vehicle seat (100). The retention device includes a base member (14, 14A, 14B, 14C, 14D) and a plurality of retention members (16, 16A, 16B, 16C, 16D) that are detachable from the base member and that retain the linear member, and the attachment positions of the plurality of retention members relative to the base member are changeable.

[0128] According to this configuration, the holding member can be attached and detached from the base member as needed, and the position of the holding member can be changed depending on the shape of the vehicle seat, thereby effectively holding the linear member in a desired shape, which is highly versatile. Furthermore, by attaching the holding member to the base after holding the linear member, the workability of holding the linear member can be improved.

[0129] (Appendix 2) In the holding device described in Appendix 1, the base member may have a plurality of mounting holes (24) for attaching a plurality of the holding members, and each of the plurality of holding members may have an engaging portion (40) that can engage with the base member.

[0138] According to this configuration, the assembly robot can grasp the gripping portion, thereby automating the attachment of the linear member to the holding device.

[0139] (Appendix 7) In the holding device described in Appendix 6, a hole portion (234) penetrating the base member 14 in the thickness direction may be formed in an area (F) of the base member that faces the gripping portion when the filamentary member is held by the multiple holding members.

[0140] According to this configuration, the base member is provided with the hole, so that contact between the assembly robot gripping the gripping portion and the base member is effectively avoided.

[0141] (Appendix 8) In the holding device described in Appendix 1, each of the multiple holding members has multiple holding portions (34), and the multiple holding portions each have multiple protrusions (218, 228) that are engageable with the linear member and protrude from the base member, and the multiple protrusions may protrude from the base member in the same direction.

[0142] According to this configuration, the protrusion can effectively suppress movement of the linear member.

[0143] (Appendix 9) In the holding device described in Appendix 8, the distance (C) between the plurality of protrusions that are located on opposite sides of the linear member when the linear member is held by the plurality of holding members in a direction perpendicular to the linear member may be smaller than the diameter (D) of the linear member.

[0144] According to this configuration, the linear member is prevented from coming off from between the protruding portions, and movement of the linear member can be effectively prevented.

[0145] (Appendix 10) In the retaining device described in Appendix 1, the retaining device may be attached to a pan frame (118) provided on a seat cushion (102) of the vehicle seat, and when viewed in the thickness direction of the pan frame, the retaining device may be positioned so as not to overlap with an airbag (AB) attached to the pan frame.

[0146] With this configuration, when the airbag is activated and deployed, contact between the airbag and the retaining device is effectively suppressed.

[0147] The present disclosure is not limited to the above disclosure, and various configurations may be adopted without departing from the gist of the present disclosure.
