Vehicle seats

Abstract

To realize a vehicle seat with a structure that makes it easy to fix predetermined components to the seat. [Solution] When attaching and fixing the fixing bracket 40 to the foot bracket 30 of the vehicle seat S, by engaging the hook portion 41 of the fixing bracket 40 with the hole portion 32a of the foot bracket 30, the movement of the fixing bracket 40 relative to the foot bracket 30 is restricted until the fixing bracket 40 is fixed to the foot bracket 30, so that the fixing bracket 40 can be suitably fixed to the predetermined position on the foot bracket 30. Furthermore, if the direction in which predetermined members (harness 60, connector 70) are attached to the fixing bracket 40 and the direction in which the hook portion 41 is engaged with the hole portion 32a are the same, the direction in which the fixing bracket 40 is attached to the foot bracket 30 and the direction in which the predetermined members are attached to the fixing bracket 40 can be aligned, making attachment and fixing easier.

Summary of the Invention

Problems to be Solved by the Invention

[0004] However, in the case of the vehicle seat of Patent Document 1 above, when fixing the heater to the foot bracket via the fixing bracket, the relative position between the fixing bracket and the foot bracket may shift, making it difficult to perform the operation of fixing the heater, which is a predetermined member, to the seat.

[0005] An object of the present invention is to provide a vehicle seat having a structure in which a predetermined member can be easily fixed to the seat.

Means for Solving the Problems

[0006] To solve the above problems, the invention according to claim 1 is A vehicle seat in which a second fixing member for fixing a predetermined member provided on the seat body is attached to a first fixing member for fixing a slide rail supporting the seat body to a vehicle body floor, The second fixing member is provided with a restricting portion that restricts the movement of the second fixing member relative to the first fixing member until the second fixing member is attached to and fixed to the first fixing member.

[0007] The invention described in claim 2 is a vehicle seat described in claim 1, The restricting portion is characterized by being a hook portion that engages with a hole provided in the first fixing member.

[0008] The invention described in claim 3 is a vehicle seat as described in claim 2, The hole is characterized in that it is provided at a lower position than the first fixing point to which the first fixing member and the second fixing member are fixed.

[0009] The invention described in claim 4 is a vehicle seat as described in claim 3, A reinforcing portion is provided near the hole in the first fixing member. The first fixing point is characterized by being located adjacent to the reinforcing portion.

[0010] The invention described in claim 5 is a vehicle seat as described in claim 2, The direction in which the predetermined member is attached to the second fixing member is the same as the direction in which the hook portion is engaged with the hole.

[0011] The invention described in claim 6 is a vehicle seat as described in claim 5, The aforementioned predetermined member includes a connector connected to the end of the harness provided on the seat body. The hook portion is characterized in that it is located further back and closer to the harness than the second fixing point where the connector and the second fixing member are fixed.

[0012] The invention described in claim 7 is a vehicle seat described in claim 1, The first fixing member is characterized by having a shape that does not overlap with the position where the predetermined member is fixed to the second fixing member.

[0013] The invention described in claim 8 is a vehicle seat as described in claim 2, The aforementioned predetermined member includes the harness provided on the seat body, The hook portion is characterized in that it is located below the third fixing point to which the harness and the second fixing member are fixed.

[0014] The invention described in claim 9 is a vehicle seat as described in claim 3, The system comprises a cover member that covers at least a portion of the first fixing member and the second fixing member, and a member that is fixed to the second fixing member and to which the cover member is attached, The attached member is characterized in that it is arranged so as to sandwich the first fixing point between itself and the hook portion.

[0015] The invention described in claim 10 is a vehicle seat as described in claim 9, The engagement point between the cover member and the attached member is characterized in that it is located in a position that does not overlap with the second fixing member in the vertical direction. [Effects of the Invention]

[0016] According to the invention described in claim 1, when attaching and fixing the second fixing member to the first fixing member, the movement of the second fixing member relative to the first fixing member is restricted by the restricting portion of the second fixing member until the second fixing member is fixed to the first fixing member, so that the second fixing member can be suitably fixed to a predetermined position on the first fixing member.

[0017] According to the invention described in claim 2, by engaging the hook portion of the second fixing member with the hole portion of the first fixing member, the movement of the second fixing member relative to the first fixing member is restricted until the second fixing member is fixed to the first fixing member, so that the second fixing member can be suitably fixed to a predetermined position on the first fixing member. In particular, as a restricting portion for restricting the movement of the second fixing member with respect to the first fixing member, by adopting a hook-shaped hook portion that can be engaged with the hole portion of the first fixing member, the positioning and movement restriction of the second fixing member with respect to the first fixing member can be easily performed.

[0018] According to the invention described in claim 3, since the hole portion of the first fixing member is provided at a position lower than the first fixing portion where the first fixing member and the second fixing member are fixed, it is easier to engage the hook portion of the second fixing member with the hole portion of the first fixing member, so that the second fixing member can be easily fixed to the first fixing member.

[0019] According to the invention described in claim 4, since the first fixing portion is located adjacent to the reinforcing portion, the rigidity in the vicinity of the first fixing portion is increased by the reinforcing portion, so that the first fixing portion where the first fixing member and the second fixing member are fixed has sufficient strength, and the posture of the second fixing member fixed to the first fixing member becomes stable.

[0020] According to the invention described in claim 5, if the direction in which a predetermined member is fixed to the second fixing member and the direction in which the hook portion is engaged with the hole portion are the same direction, the direction in which the second fixing member is attached to the first fixing member and the direction in which the predetermined member is attached to the second fixing member can be aligned, so that the attachment and fixing are easier to perform.

[0021] According to the invention described in claim 6, since the hook portion is located closer to the harness behind the second fixing portion where the connector, which is a predetermined member, and the second fixing member are fixed, the connector and the hook portion do not interfere with each other. Also, since there are a hook portion and a harness behind the second fixing portion, it becomes easier to insert, for example, a connector on the vehicle floor side into the connector on the vehicle seat side at the second fixing portion.

[0022] According to the invention described in claim 7, the shape of the first fixing member is such that there is no portion that overlaps with the position where a predetermined member is fixed to the second fixing member. Therefore, even if a part of the predetermined member protrudes from the second fixing member when the predetermined member is fixed to the second fixing member, the protruding portion will not interfere with the first fixing member, and thus the second fixing member can be reliably fixed to the first fixing member.

[0023] According to the invention described in claim 8, the hook portion is located below the third fixing point where the harness, which is a predetermined member, and the second fixing member are fixed, so that the harness and the hook portion do not interfere with each other. Furthermore, having the hook portion located below the third fixing point makes it easier to engage the hook portion with the hole, and thus easier to fix the second fixing member to the first fixing member.

[0024] According to the invention described in claim 9, since there is a first fixing point between the member to be attached and the hook portion, the member to be attached and the hook portion are spaced apart, so that the member to be attached and the hook portion do not interfere with each other. Therefore, the member to be attached does not hinder the attachment of the second fixing member to the first fixing member, and the second fixing member can be suitably attached to the first fixing member.

[0025] According to the invention described in claim 10, by positioning the attachment point between the cover member and the attached member so that it does not overlap with the second fixing member in the vertical direction, the external force acting on the cover member is less likely to be transmitted to the second fixing member, thus reducing the load on the second fixing member.

[0027] Hereinafter, embodiments of the vehicle seat according to the present invention will be described in detail with reference to the drawings. However, the embodiments described below are subject to various technically preferred limitations for carrying out the present invention, but the scope of the present invention is not limited to the following embodiments and illustrated examples. In the following explanation, we will define the front-to-back, left-to-right, and up-and-down directions. Here, the back of the seat is referred to as "rear," the opposite side as "front," the left side when seated and looking straight ahead as "left," and the right side when seated and looking straight ahead as "right." The up-and-down direction corresponds to the vertical direction. In other words, the width of the seat corresponds to the left-to-right direction.

[0028] The vehicle seat S of this embodiment has a seat body S3 that includes a seat cushion S1 as a seating area and a seat back S2 as a backrest, as shown in Figure 1, for example. The seat body S3 is supported by a slide rail 19, which will be described later, and is fixed to the vehicle floor via the slide rail 19, etc.

[0029] Inside the seat cushion S1, for example, is a cushion frame 1 as shown in Figure 2. The seat cushion S1 is constructed by covering this cushion frame 1 with a pad made of urethane foam or the like, and then covering that with a surface material made of fabric or leather. Although not shown in the diagram, the seatback S2 is similarly constructed by covering the back frame, which acts as the framework, with padding and upholstery material.

[0030] The cushion frame 1 includes, for example, a pair of left and right side frames 10, a first connecting frame 11 that connects one end of the pair of left and right side frames, and a second connecting frame 12 that connects the other ends of the pair of left and right side frames, as shown in Figure 2. This cushion frame 1 further includes a pan frame 13 positioned in front of the first connecting frame 11. The pair of left and right side frames 10 in this example have an asymmetrical shape.

[0031] The side frames 10 are frames made of metal plates and are arranged in pairs, spaced apart on the left and right sides. The first connecting frame 11 and the second connecting frame 12 are positioned spaced apart from each other in the front-to-back direction. The first connecting frame 11 is a so-called front frame made of a metal pipe with a circular cross-section, and it connects the front ends of the pair of side frames 10. The second connecting frame 12 is a so-called rear frame made of a metal pipe with a circular cross-section, and it connects the rear ends of the pair of side frames 10. The pan frame 13 is a frame made of metal plates, and it connects the front ends of a pair of side frames 10 at a position in front of the first connecting frame 11.

[0032] Furthermore, the cushion frame 1 is installed on the vehicle floor via a slide rail 19 or the like. The slide rail 19 includes a pair of lower rails 18 that extend in the front-rear direction and are spaced apart from each other on the left and right, and a pair of upper rails 17 that are slidably engaged with each lower rail 18 in the front-rear direction. The lower rail 18 is fixed to the vehicle floor (not shown) by a foot bracket 30, which will be described later, and the upper rail 17, which is slidably mounted on the lower rail 18, is fixed to the cushion frame 1. In other words, this vehicle seat S is installed on the vehicle floor so that it can slide back and forth. Furthermore, a cover member 15 is provided on the tip side of the lower rail 18, and in Figures 1 to 4, most of the foot bracket 30 that fixes the lower rail 18 to the vehicle floor is covered by the cover member 15.

[0033] In this embodiment, the slide rail 19 is an electrically operated sliding mechanism that moves the upper rail 17 along the lower rail 18 by the drive of a motor 16 located on the upper rail 17 side, thereby sliding the seat back and forth. For example, a motor 16 located on the cushion frame 1 on the upper rail 17 side rotates a pinion gear that meshes with a rack provided along the extending direction of the lower rail 18, thereby moving the upper rail 17 along the lower rail 18. The configuration and operation of the electrically operated sliding rail 19 are the same as those of conventionally known systems, so they will not be described in detail here.

[0034] Furthermore, the vehicle seat S is equipped with electrical components 20, which are installed on the cushion frame 1. The electrical component 20 installed on the cushion frame 1 is, for example, a blower for drawing air into the seat cushion S1. The predetermined components connected to this electrical component 20 and provided on the seat body S3 are the harness 60 and connector 70, which will be described later.

[0035] The vehicle seat S of this embodiment includes, for example, as shown in Figures 3 to 20, a foot bracket 30 which is a first fixing member for fixing a slide rail 19 (lower rail 18) that supports the seat body S3 to the vehicle floor (not shown), and a fixing bracket 40 which is a second fixing member for fixing a predetermined member provided on the seat body S3. The fixing bracket 40 for securing a predetermined component is attached to and fixed to the foot bracket 30. The fixing bracket 40 is provided with a restricting portion (a hook portion 41, described later) that restricts the movement of the fixing bracket 40 relative to the foot bracket 30 until the fixing bracket 40 is attached to and fixed to the foot bracket 30. Furthermore, the fixing bracket 40 also has the function of fixing a predetermined member to the foot bracket 30.

[0036] The foot bracket 30 is, for example, a member formed by press-forming sheet metal, and has a bracket body portion 31 for fixing the slide rail 19 (lower rail 18) to the vehicle floor (not shown), and a flange portion 32 for fixing the fixing bracket 40 to the foot bracket 30. A reinforcing portion 33 is provided between the bracket body portion 31 and the flange portion 32 to reinforce the flange portion 32 (see Figures 6, 7, and 14).

[0037] The bracket body portion 31 is provided with bolt holes 31a through which fixing members for fixing the foot bracket 30 to the vehicle floor (not shown) are inserted. The flange portion 32 is provided with a hole 32a into which the hook portion 41 of the fixing bracket 40 is engaged, and a bolt hole 32b (see Figure 16) through which a bolt B for fixing the fixing bracket 40 to the foot bracket 30 is inserted.

[0038] The reinforcing portion 33 is, for example, a bent portion formed by bead processing in press working. By providing this reinforcing portion 33 near the flange portion 32, the rigidity of the flange portion 32 can be increased, thereby increasing the strength of the foot bracket 30 to which the fixing bracket 40 is fixed.

[0039] The fixing bracket 40 is, for example, a component formed by press-forming sheet metal. The fixing bracket 40 is provided with a hook portion 41 which acts as a restricting portion that engages with the hole 32a of the foot bracket 30 (flange portion 32), and a bolt hole 42 (see Figure 16) through which a bolt B that fixes the fixing bracket 40 to the foot bracket 30 is inserted. The hook portion 41 is formed to have a hook shape. Furthermore, the fixing bracket 40 is provided with three mounting holes 43, 44, and 45 (see Figures 10 to 12) for attaching and fixing a predetermined component to the fixing bracket 40. In this embodiment, the specified components are the harness 60 and connector 70, which are connected to the electrical component 20 and provided on the seat body S3.

[0040] Furthermore, there are steps in the areas of the fixing bracket 40 where mounting holes 43, 44, and 45 are provided. Here, the area with mounting hole 43 is the middle section, the area with mounting hole 44 is the lower section, and the area with mounting hole 45 is the upper section. In this way, by creating a step in the area where the mounting holes (43, 44, 45) of the fixing bracket 40 are provided, it is possible to suppress the protrusion of the three predetermined members in the height direction (up and down direction) even when the sizes of the three predetermined members to be attached to the three mounting holes (43, 44, 45) are different. Specifically, as will be described later, a relatively small connector 70 is attached to the middle mounting hole 43, a relatively large connector 70 is attached to the lower mounting hole 44, and a flat harness 60 is attached to the upper mounting hole 45. This allows the height positions of the relatively small connector 70, the relatively large connector 70, and the flat harness 60 to be aligned to almost the same position, thereby reducing the thickness of the assembly formed by these components being attached to the fixing bracket 40 and preventing the assembly from becoming larger in the height direction (see Figures 6 and 7). By reducing the thickness of the assembly formed by attaching the connector 70 and harness 60 to the fixing bracket 40, it becomes possible to install the assembly in a narrow area around the foot bracket 30.

[0041] Furthermore, the fixing bracket 40 is provided with a notched recess 41a adjacent to the base of the hook portion 41 (see Figures 14 and 15). By providing a recess 41a next to the base of the hook portion 41, the rigidity of the base of the hook portion 41 is reduced, making it easier to bend, thus making it easier to form the hook portion 41. Here, in order to align the left and right positions of the base of the hook portion 41 in the front-to-back direction, a recess 41a is provided on the left side of the base of the hook portion 41. By doing so, the bending force is applied evenly to the hook portion 41, so that the hook portion 41 can be formed to a suitable degree.

[0042] Furthermore, the fixing bracket 40 is provided with two fixing end pieces 46 (see Figures 10 to 12) for fixing the attached member 50 to which the cover member 15 is attached. Furthermore, when the cover member 15 is attached to the attached member 50, the cover member 15 covers at least a portion of the fixing bracket 40, and the hook portion 41 of the fixing bracket 40 is positioned so as not to overlap with the cover member 15 when viewed from above (see Figures 3 and 4). In other words, the hook portion 41 of the fixing bracket 40 and the cover member 15 are positioned so as not to interfere with each other.

[0043] The attached member 50 is, for example, a member formed by welding together two metal rod-shaped members. Here, two metal rods are joined by a weld bead, which is a welded portion 51, to form a retained member 50 that has a roughly Y-shape. The attached member 50 is fixed to the fixed end piece 46 of the fixed bracket 40 by a welded portion 51 which is a weld bead. The attached member 50, which is made of a metal rod-shaped member, is a member that can undergo elastic deformation to the extent that the rod-shaped member bends.

[0044] Harness 60 is a so-called wire harness or cable harness, a bundle of wires used as in-vehicle wiring for power supply and signal communication in a vehicle. In the vehicle seat S of this embodiment, the harness 60 is fixed to the fixing bracket 40. One end of this harness 60 is connected to connector 70, and the other end is connected to the electrical component 20 on the seat body S3 side.

[0045] The connector 70 is connected to the end of the harness 60, which is located on the seat body S3. In the vehicle seat S of this embodiment, a relatively small connector 70 is located on the right side of the fixing bracket 40, and a relatively large connector 70 is located on the left side, and these two connectors 70 are fixed to the fixing bracket 40. This connector 70 is a so-called female connector, and a male connector connected to the end of a harness (not shown) extending from the floor side of the vehicle is inserted into the connector 70 on the seat body S3 side, thereby electrically connecting the vehicle side and the electrical components 20 on the seat body S3 side.

[0046] Next, the procedure for assembling and fixing each of the above-mentioned parts (foot bracket 30, fixing bracket 40, attachment member 50, harness 60, connector 70, cover member 15) in the vehicle seat S of this embodiment, as well as the manner in which they are fixed, will be described. Note that the order in which the above parts are fixed in place does not have to be in the order described below; any order that makes it easy to assemble and fix the parts in place is acceptable.

[0047] [Securing the foot bracket to the mounting bracket] When attaching and fixing the fixing bracket 40 to the foot bracket 30, first, the hook portion 41 of the fixing bracket 40 is engaged with the hole portion 32a of the foot bracket 30, and the fixing bracket 40 is placed on the flange portion 32 of the foot bracket 30 so that the fixing bracket 40 is aligned with the foot bracket 30. At this time, the movement of the fixing bracket 40 relative to the foot bracket 30 is restricted because the hook portion 41 of the fixing bracket 40 is engaged with the hole portion 32a of the foot bracket 30.

[0048] Next, the bolt hole 42 of the fixing bracket 40 and the bolt hole 32b of the foot bracket 30 are aligned, and bolt B is inserted through the aligned bolt holes (42, 32b). The bolt B is then screwed onto the nut N located on the lower surface of the flange portion 32 to fix the fixing bracket 40 to the foot bracket 30 (see Figure 16). At this time, the hook portion 41 of the fixing bracket 40 is engaged with the hole 32a of the foot bracket 30, so that when the bolt B is screwed onto the nut N, the movement of the fixing bracket 40 relative to the foot bracket 30 is restricted so that the fixing bracket 40 does not rotate together with the bolt B.

[0049] In this way, when attaching and fixing the fixing bracket 40 to the foot bracket 30, by engaging the hook portion 41 of the fixing bracket 40 with the hole portion 32a of the foot bracket 30, the movement of the fixing bracket 40 relative to the foot bracket 30 is restricted until the fixing bracket 40 is fixed to the foot bracket 30, so that the fixing bracket 40 can be suitably fixed to the predetermined position on the foot bracket 30. In particular, by employing a hook-shaped portion 41 that can engage with the hole 32a of the foot bracket 30 as a restricting portion for restricting the movement of the fixing bracket 40 relative to the foot bracket 30, the positioning and movement restriction of the fixing bracket 40 relative to the foot bracket 30 can be easily performed. Furthermore, since the movement of the fixing bracket 40 relative to the foot bracket 30 is restricted by the cooperation of the hole 32a of the foot bracket 30 and the hook portion 41 of the fixing bracket 40, the hole 32a of the foot bracket 30 (flange portion 32) can also be said to be a restricting portion that restricts the movement of the fixing bracket 40 relative to the foot bracket 30.

[0050] Here, the position where the fixing bracket 40 is fixed to the flange portion 32 of the foot bracket 30 with bolt B is considered to be the first fixing point P1 where the foot bracket 30 and the fixing bracket 40 are fixed together. Furthermore, the hole 32a in the flange portion 32 of the foot bracket 30 is located at a lower position than the first fixing point P1 (see Figures 7 and 16). Since the hole 32a of the foot bracket 30 (flange portion 32) is located lower than the first fixing point P1, it is easier to engage the hook portion 41 with the hole 32a of the flange portion 32, and easier to place the fixing bracket 40 on the flange portion 32 of the foot bracket 30. Therefore, it becomes possible to easily fix the fixing bracket 40 to the foot bracket 30.

[0051] Furthermore, since a reinforcing portion 33 is provided near the flange portion 32 of the foot bracket 30 and adjacent to the flange portion 32, the rigidity of the flange portion 32 is increased by the reinforcing portion 33. Although there are concerns about a decrease in the strength of the flange portion 32 of the foot bracket 30 because through holes such as hole 32a and bolt hole 32b are provided in the flange portion 32, the rigidity of the flange portion 32 is increased by the reinforcing portion 33, so the flange portion 32 has sufficient strength. Furthermore, the first fixing point P1 is located adjacent to the reinforcing part 33, and the rigidity of the flange part 32 is increased by the reinforcing part 33. Therefore, the first fixing point P1 to which the foot bracket 30 and the fixing bracket 40 are fixed has sufficient strength, and the posture of the fixing bracket 40 fixed to the foot bracket 30 becomes stable.

[0052] [Securing the attached member to the fixed bracket] The attached member 50 is a member formed by welding two metal rod-shaped members together and joining them at a welded portion 51, and has a roughly Y-shape. When fixing the attachment member 50 to the fixing bracket 40, one end of the bifurcated member is welded to the left fixing end piece 46 of the fixing bracket 40, and the other end of the bifurcated member is welded to the right fixing end piece 46 of the fixing bracket 40. Here, the bifurcated ends of the attachment member 50 are joined to the fixed end piece 46 by welding portions 51, thereby fixing the attachment member 50 to the fixed bracket 40 (see Figures 10 to 12).

[0053] The attached member 50, which is fixed to the fixing bracket 40, is positioned so as to sandwich the first fixing point P1 between it and the hook portion 41 of the fixing bracket 40 (see Figures 10 to 12). There is a first fixing point P1 between the attached member 50 and the hook portion 41, and the attached member 50 and the hook portion 41 are spaced apart, and the hook portion 41 is positioned behind the attached member 50, so the attached member 50 and the hook portion 41 do not interfere with each other, the attached member 50 does not hinder the attachment of the fixing bracket 40 to the foot bracket 30, and the fixing bracket 40 can be suitably attached to the foot bracket 30.

[0054] The procedure for fixing the attachment member 50 to the fixing bracket 40 is not limited to the above embodiment. For example, one end of one of two metal rod-shaped members may be welded to the left fixing end piece 46 of the fixing bracket 40, and one end of the other metal rod-shaped member may be welded to the right fixing end piece 46 of the fixing bracket 40. Then, the other ends of the two metal rod-shaped members may be welded together to form a retaining member 50, thereby fixing the retaining member 50, which has a roughly Y shape, to the fixing bracket 40.

[0055] [Securing the cover member to the attached member] The cover member 15 is a resin member that covers at least a portion of the foot bracket 30 and the fixing bracket 40, as shown in Figures 3 and 4, for example. On the back surface of the cover member 15, for example, as shown in Figure 13, a claw portion 15a is provided for engaging the cover member 15 with the engagement member 50. The cover member 15 in this embodiment is provided with three claw portions 15a, and the cover member 15 is fixed to the attached member 50 in such a manner that the claw portions 15a are engaged with the three arm portions of the attached member 50, which has a roughly Y-shape.

[0056] In particular, the claw portion 15a of the cover member 15 is provided on the cover member 15 such that the point where the claw portion 15a of the cover member 15 engages with the engaged member 50 is located in a position that does not overlap with the fixing bracket 40 in the vertical direction. For example, when an external force is applied to the cover member 15, such as when an occupant steps on it on the floor of a vehicle, the attached member 50 elastically deforms to absorb and release that external force. In this case, by ensuring that the attachment point between the cover member 15 and the attached member 50 is positioned so as not to overlap with the fixing bracket 40 in the vertical direction, the external force acting on the cover member 15 is less likely to be transmitted to the fixing bracket 40, thereby preventing a load from being placed on the fixing bracket 40.

[0057] [Securing the harness and connector to the mounting bracket] When attaching and securing the harness 60 and connector 70 to the fixing bracket 40, for example, as shown in Figures 5 to 12, the clips 61 provided on the harness 60 and the clips 71 provided on the connector 70 are used to secure them to the mounting holes (43, 44, 45) of the fixing bracket 40.

[0058] When attaching and securing the connector 70 to the fixing bracket 40, for example, as shown in Figures 5, 8 to 10, the projection of the clip 71 on the relatively small connector 70 is inserted into the mounting hole 43 of the fixing bracket 40 for attachment and securing, and the projection of the clip 71 on the relatively large connector 70 is inserted into the mounting hole 44 of the fixing bracket 40 for attachment and securing. Here, the direction in which the connector 70 is attached to the fixing bracket 40 is the same as the direction in which the hook portion 41 of the fixing bracket 40 is engaged with the hole portion 32a of the foot bracket 30. If the direction in which the connector 70 is attached to the fixing bracket 40 and the direction in which the hook portion 41 is engaged with the hole portion 32a are the same, the orientation of each part attached to the foot bracket 30 can be aligned, making it easier to attach and fix each part. The clip 71 provided on the connector 70 may be integrally molded with the connector 70, or it may be a separate clip 71 that is attached to the connector 70 afterwards.

[0059] Furthermore, the position where the connector 70 is fixed to the fixing bracket 40 is considered to be the second fixing point P2 where the fixing bracket 40 and the connector 70 are fixed together. Furthermore, the hook portion 41 of the fixing bracket 40 is located further back and closer to the harness 60 than the second fixing point P2 where the connector 70 and the fixing bracket 40 are fixed (see Figures 5 and 8). The hook portion 41 is located behind this second fixing point P2, preventing interference between the connector 70 and the hook portion 41. Furthermore, the presence of the hook portion 41 and harness 60 behind the second fixing point P2 makes it easier to insert the male connector (not shown) on the vehicle floor into the connector 70 of the second fixing point P2.

[0060] When attaching and securing the harness 60 to the fixing bracket 40, for example, as shown in Figures 5, 10, and 7, the protrusions of the clips 61 provided on the harness 60 are inserted into the mounting holes 45 of the fixing bracket 40 to secure it. Here, the direction in which the harness 60 is attached to the fixing bracket 40 is the same as the direction in which the hook portion 41 of the fixing bracket 40 is engaged with the hole portion 32a of the foot bracket 30. If the direction in which the harness 60 is attached to the fixing bracket 40 and the direction in which the hook portion 41 is inserted into the hole portion 32a are the same, the orientation of each part attached to the foot bracket 30 can be aligned, making it easier to attach and fix each part.

[0061] Furthermore, the position where the harness 60 is fixed to the fixing bracket 40 is defined as the third fixing point P3 where the fixing bracket 40 and the harness 60 are fixed together. At this time, the hook portion 41 of the fixing bracket 40 is located below the third fixing point P3 to which the harness 60 and the fixing bracket 40 are fixed (see Figure 7). The hook portion 41 is located below this third fixing point P3, so that the harness 60 and the hook portion 41 do not interfere with each other. Furthermore, the position of the hook portion 41 below the third fixing point P3 makes it easier to engage the hook portion 41 with the hole portion 32a, and thus easier to fix the fixing bracket 40 to the foot bracket 30.

[0062] Furthermore, the foot bracket 30 has a shape that does not overlap with the position where the harness 60 and connector 70 (in this case, the relatively small connector 70) are fixed to the fixing bracket 40, as shown in Figure 9, for example. Specifically, the flange portion 32 of the foot bracket 30 only needs to be large enough to have a hole 32a into which the hook portion 41 is inserted, and a portion into which the bolt B is screwed onto the nut N, and has a constricted shape to avoid the position (mounting hole 43) where a relatively small connector 70 is fixed to the fixing bracket 40. Because the foot bracket 30 is formed in this constricted shape, when the harness 60 and connector 70 are fixed to the fixing bracket 40, even if the protrusions of the clips (61, 71) of the harness 60 and connector 70 protrude to the lower side of the fixing bracket 40, the clips (61, 71) will not interfere with the foot bracket 30, thus ensuring that the fixing bracket 40 is securely fixed to the foot bracket 30.

[0063] Next, the procedure for fixing the fixing bracket 40, the attachment member 50, the harness 60, and the connector 70 to the foot bracket 30 will be described. Here, we will explain using the example of a case where the member to be attached 50 is already fixed to the fixing bracket 40, and the fixing bracket 40 and the member to be attached 50 are treated and fixed together as a single unit.

[0064] [Step 1] In the first step, the harness 60 and connector 70 are first fixed to the fixing bracket 40, as shown in Figure 17. Specifically, the clips 71 of the relatively small connector 70 are attached to the mounting holes 43 of the fixing bracket 40 for securing, and the clips 71 of the relatively large connector 70 are attached to the mounting holes 44 of the fixing bracket 40 for securing. In addition, the clips 61 provided on the harness 60 are attached to the mounting holes 45 of the fixing bracket 40 for securing. The order in which the harness 60 and connector 70 are fixed to the fixing bracket 40 is arbitrary; they should be fixed in any order that is easiest for the worker.

[0065] Next, as shown in Figure 18, the fixing bracket 40, to which the harness 60 and connector 70 are fixed, is secured to the foot bracket 30. As described above, after engaging the hook portion 41 of the fixing bracket 40 with the hole portion 32a of the foot bracket 30 and aligning it, the bolt B is screwed onto the nut N to fix the fixing bracket 40 to the foot bracket 30. In this way, the movement of the fixing bracket 40 relative to the foot bracket 30 is restricted until the fixing bracket 40 is fixed to the foot bracket 30, so that the fixing bracket 40 can be suitably fixed to the predetermined position on the foot bracket 30.

[0066] In this way, the fixing bracket 40 can be fixed to the foot bracket 30, as shown in Figure 5. In this first procedure, the direction in which the harness 60 and connector 70 are attached to the fixing bracket 40 and the direction in which the hook portion 41 is engaged with the hole portion 32a are the same, making it easier to fix the harness 60, connector 70 and fixing bracket 40 to the foot bracket 30, and allowing each part to be fixed in a suitable manner.

[0067] In particular, with the first procedure, the harness 60 and connector 70 can be fixed together to the foot bracket 30 along with the fixing bracket 40. This makes the fixing process easier than individually fixing the harness 60 and connector 70 in the narrow area around the foot bracket 30.

[0068] [Step 2] In the second step, first, the fixing bracket 40 is fixed to the foot bracket 30, as shown in Figure 19. As described above, after engaging the hook portion 41 of the fixing bracket 40 with the hole portion 32a of the foot bracket 30 and aligning it, the bolt B is screwed onto the nut N to fix the fixing bracket 40 to the foot bracket 30. In this way, the movement of the fixing bracket 40 relative to the foot bracket 30 is restricted until the fixing bracket 40 is fixed to the foot bracket 30, so that the fixing bracket 40 can be suitably fixed to the predetermined position on the foot bracket 30.

[0069] Next, as shown in Figure 20, the harness 60 and connector 70 are fixed to the fixing bracket 40 which is fixed to the foot bracket 30. Specifically, the clips 71 of the relatively small connector 70 are attached to the mounting holes 43 of the fixing bracket 40 for securing, and the clips 71 of the relatively large connector 70 are attached to the mounting holes 44 of the fixing bracket 40 for securing. In addition, the clips 61 provided on the harness 60 are attached to the mounting holes 45 of the fixing bracket 40 for securing. The order in which the harness 60 and connector 70 are fixed to the fixing bracket 40 is arbitrary; they should be fixed in any order that is easiest for the worker.

[0070] In this way, the fixing bracket 40 can be fixed to the foot bracket 30, as shown in Figure 5. In this second procedure, the direction in which the hook portion 41 is inserted into the hole portion 32a and the direction in which the harness 60 and connector 70 are attached to the fixing bracket 40 are in the same orientation. Therefore, it is easier to fix the fixing bracket 40, harness 60 and connector 70 to the foot bracket 30, and each part can be fixed in a suitable manner.

[0071] In particular, with the second procedure, the fixing bracket 40, harness 60, and connector 70 can be handled individually and each can be secured separately. This allows for more maneuverable fixing work in the narrow area around the foot bracket 30 compared to the first procedure, where the harness 60 and connector 70 fixed to the fixing bracket 40 are handled together.

[0072] As described above, the vehicle seat S of this embodiment has a structure that makes it easy to fix the fixing bracket 40, harness 60 and connector 70 to the foot bracket 30 which fixes the slide rail 19 (lower rail 18) supporting the seat body S3 to the vehicle floor (not shown), and the fixing bracket 40, harness 60 and connector 70 can be suitably fixed to the foot bracket 30.

[0073] In the embodiments described above, a hook portion 41 that engages with the hole 32a of the foot bracket 30 was used as an example of a restricting portion that restricts the movement of the fixing bracket 40 relative to the foot bracket 30 until the fixing bracket 40 is attached to and fixed to the foot bracket 30. However, the present invention is not limited to this, and may also be a restricting portion that utilizes a groove-and-groove fitting mechanism or a restricting portion that utilizes a magnet.

[0074] Furthermore, in the above embodiments, a harness 60 and a connector 70 were described as examples of predetermined members fixed to the fixing bracket 40, but the present invention is not limited thereto, and the predetermined members fixed to the fixing bracket 40 may be sensors that detect the load of a person sitting on the vehicle seat S.

[0075] Furthermore, in the above embodiments, the reinforcing portion 33 for reinforcing the flange portion 32 was described as a bent portion formed by bead processing in press working, but the present invention is not limited thereto, and for example, the reinforcing portion 33 may be formed by providing a thickened portion between the bracket body portion 31 and the flange portion 32. The thickened portion may be an embodiment in which additional sheet metal is fixed or an embodiment in which a weld bead is formed.

[0076] Furthermore, in the embodiments described above, the attached member 50 to which the cover member 15 is attached was described as being made by welding together two metal rod-shaped members, but the present invention is not limited thereto. Any attached member 50 that can undergo elastic deformation to the extent of bending may be used, for example, a metal wire or a thin plate, or a resin rod-shaped member, wire or thin plate.

[0077] Furthermore, it goes without saying that other specific structural details can be modified as needed. [Explanation of symbols]
