[0016] The invention according to claim 11 is the vehicle seat according to claim 10, wherein the harness movement restricting member is disposed offset to the side where the electrical component is installed in the width direction of the cushion frame.

Advantages of the Invention

[0017] According to the invention of claim 1, since the harness movement restricting member that suppresses the downward movement of the harness connected to the electrical component is provided, even if the harness becomes loose and hangs down, the harness movement restricting member can support the harness from below, and the harness does not move downward from the harness movement restricting member.

[0018] According to the invention described in claim 2, since the harness movement restraining member has a first engaging portion engaged with the pressure receiving member, the harness movement restraining member can be easily attached to the pressure receiving member.

[0019] According to the invention described in claim 3, since the pressure receiving member has a flat surface portion including a flat region and the first engaging portion is engaged with the flat surface portion, the harness movement restraining member can be easily attached to the pressure receiving member.

[0020] According to the invention described in claim 4, since a engaging hole is formed in the flat surface portion of the pressure receiving member and the first engaging portion which is a hook-shaped member is engaged with the engaging hole, the harness movement restraining member can be easily attached to the pressure receiving member.

[0021] According to the invention described in claim 5, since the harness movement restraining member has a second engaging portion engaged with the bracket of the electrical component, the harness movement restraining member can be easily attached to the bracket of the electrical component installed on the pan frame. Since the pan frame is disposed on the front side of the first connecting frame in the cushion frame, it becomes possible to attach the harness movement restraining member in a wide range in the front-rear direction, and it becomes possible to suitably support the harness extending in the front-rear direction of the vehicle seat.

[0022] According to the invention described in claim 6, since the second engaging portion is engaged at a position higher than the first engaging portion, the one end side of the harness movement restraining member disposed at a position closer to the electrical component is pulled up to a high position by the second engaging portion, so that it becomes easier to suppress the harness connected to the electrical component from moving downward.

[0023] According to the invention described in claim 7, the harness movement restraining member can be easily attached to the bracket of the electrical component by engaging the second engaging portion which is an elastic band member with the hook portion of the bracket. Furthermore, the contraction of the band member attached to the hook portion of the bracket causes one end of the harness movement suppression member to be pulled towards the bracket side of the electrical component, making it easier to suppress the downward movement of the harness connected to the electrical component.

[0024] According to the invention described in claim 8, since the harness movement suppression member is a sheet-like member made of fabric, resin sheet material, etc., it can be formed to a size and shape corresponding to the area in which the harness is routed, thereby suitably supporting the harness.

[0025] According to the invention described in claim 9, since the harness movement suppression member is a sheet-like member made of fabric, resin sheet material, etc., it can be formed to a size and shape corresponding to the area in which the harness is routed, thereby suitably supporting the harness. In particular, in the sheet-like member (harness movement suppression member), the width of one end where the second engagement portion is provided is wider than the width of the other end where the first engagement portion is provided. Since the width of one end of the harness movement suppression member positioned closer to the electrical component is wider, it becomes possible to support a wider range of harnesses connected to the electrical component.

[0026] According to the invention described in claim 10, the harness movement restraining member is smaller compared to one that covers the entire width of the cushion frame, thus enabling weight reduction and cost reduction. Furthermore, it minimizes interference with the placement of other components, thus increasing design flexibility. Additionally, installation becomes easier.

[0027] According to the invention described in claim 11, the harness movement suppression member is positioned biased toward the installation location of the electrical component to which the harness is wired, so that the harness can be supported efficiently while keeping the size of the harness movement suppression member down.

[0029] 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.

[0030] The vehicle seat S of this embodiment includes, for example, a seat cushion S1 as a seating area and a seat back S2 as a backrest, as shown in Figure 1. Inside the seat cushion S1, for example, is a cushion frame 1 as shown in Figures 2 and 3. 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.

[0031] 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 Figures 2 and 3. 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.

[0032] 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.

[0033] Furthermore, the cushion frame 1 is installed on the vehicle via a slide rail mechanism 19 and the like. The slide rail mechanism 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 floor of a vehicle (not shown), 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. In this embodiment, the slide rail mechanism 19 is an electrically operated slide type that moves the upper rail 17 along the lower rail 18 by driving 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 mechanism 19 are the same as those known to date, so they will not be described in detail here.

[0034] Furthermore, the vehicle seat S of this embodiment includes, for example, as shown in Figures 2 to 6, a cushion frame 1 having a pair of left and right side frames 10, a first connecting frame 11 connecting the front parts of the pair of left and right side frames 10, a second connecting frame 12 connecting the rear parts of the pair of left and right side frames 10, and a pan frame 13 positioned in front of the first connecting frame 11; a pressure receiving member 20 positioned between the pair of left and right side frames 10 to receive the load from the occupant; electrical components 30 installed on the cushion frame 1; a harness 40 connected to the electrical components 30; and a harness movement suppression member 50 arranged to support the harness 40 from below in order to prevent the harness 40 from moving downward.

[0035] As described above, the vehicle seat S of this embodiment is equipped with electrical components 30, and a harness movement suppression member 50 is provided to prevent the harness 40 connected to supply power to the electrical components 30 from sagging or hanging down. For example, if one end of a harness 40 is connected to an electrical component 30 installed on a cushion frame 1, and the other end of the harness 40 is connected to the floor of the vehicle, when the vehicle seat S is slid back and forth, the two ends of the harness 40 come into close proximity, causing slack in the harness 40, and a portion of the harness 40 may hang down. Even if the harness 40 becomes loose and hangs down in this way, the harness movement suppression member 50 supports the harness 40 from below, thereby preventing the harness 40 from moving below the harness movement suppression member 50.

[0036] The following describes a vehicle seat S equipped with a harness movement restraint member 50.

[0037] The pressure-receiving member 20 is a metal plate that receives the load from the seated person, with its front end 21 hooked onto the first connecting frame 11 and its rear end 22 hooked onto the second connecting frame 12, and is suspended between the first connecting frame 11 and the second connecting frame 12. Between the front end 21 and the rear end 22 of the pressure-receiving member 20, there is a receiving recess 23 capable of accommodating a pad, and a flat portion 24 including a flat area is formed on the bottom surface of the receiving recess 23. A pair of left and right locking holes 24h are formed in the flat portion 24 of the receiving recess 23 for attaching the harness movement suppression member 50. Furthermore, the area surrounding the bottom surface of the receiving recess 23, including the area from the front end 21 to the bottom surface of the receiving recess 23 and the area from the rear end 22 to the bottom surface of the receiving recess 23, is generally composed of an inclined surface that slopes downward from the edge of the receiving recess 23 to the bottom surface.

[0038] The electrical components 30 are attached to the lower surface of the pan frame 13 in the cushion frame 1 via a bracket 31. The bracket 31 is provided with a hook portion 31a for attaching the harness movement restraint member 50. The electrical component 30 in this embodiment is a blower for drawing air into the seat cushion S1. Furthermore, the electrical component 30 is positioned on the front right side of the cushion frame 1 so as not to interfere with the motor 16 of the slide rail mechanism 19.

[0039] The harness 40 is a cable for supplying power to the electrical components 30, and most of it is routed under the pressure receiving member 20. In this case, the harness 40 is arranged to extend in the front-to-rear direction of the vehicle seat S.

[0040] The harness movement suppression member 50 has, for example, as shown in Figure 7, a first attachment portion 51 that engages with the pressure receiving member 20 for attaching the harness movement suppression member 50 to the pressure receiving member 20, and a second attachment portion 52 that engages with the bracket 31 for attaching the harness movement suppression member 50 to the bracket 31 of the electrical component 30. In other words, the harness movement suppression member 50 has a first engagement portion 51 and a second engagement portion 52 for attaching the harness movement suppression member 50 to the vehicle seat S.

[0041] The harness movement restraint member 50 is a sheet-like member made of fabric or resin sheet material, and has a size that can cover a predetermined area. The harness movement suppression member 50 in this embodiment has a width that is sufficient to cover about one half (one half in the left-right direction) of the pressure receiving member 20, and is able to cover roughly the area in which the harness 40 is routed. In particular, the harness movement restraining member 50 is formed such that the width of the end on which the second engagement portion 52 is provided is wider than the width of the other end on which the first engagement portion 51 is provided.

[0042] The first engaging portion 51 is a hook-shaped member that engages with the flat portion 24 of the pressure-receiving member 20, and the hook-shaped first engaging portion 51 engages with an engaging hole 24h formed in the flat portion 24. Here, a pair of left and right first engagement portions 51 are fixed to the other end of the harness movement suppression member 50, and by engaging the pair of first engagement portions 51 with a pair of engagement holes 24h formed in the flat portion 24, the other end of the harness movement suppression member 50 can be attached to the pressure receiving member 20. This first attachment portion 51 is, for example, a hook-shaped member made of resin that has a roughly J-shape when viewed from the side, and is sewn and fixed to the other end of the harness movement restraining member 50.

[0043] The second engagement portion 52 is an elastic band member that is attached to the bracket 31 of the electrical component 30, and the second engagement portion 52, being a band member, is attached to a hook portion 31a formed on the bracket 31. Here, both ends of a band member, which is the second engagement portion 52, are sewn and fixed to one end of the harness movement suppression member 50. By engaging the handle-shaped band member (second engagement portion 52) with the hook portion 31a of the bracket 31, one end of the harness movement suppression member 50 can be attached to the bracket 31 of the electrical component 30. This second attachment portion 52 is, for example, a rubber band member, and both ends of the band member are sewn to one end of the harness movement restraint member 50 with spaced apart, so that the band member is fixed to one end of the harness movement restraint member 50 in the shape of a handle.

[0044] Furthermore, the second attachment portion 52, which is attached to the bracket 31 of the electrical component 30, is positioned higher than the first attachment portion 51, which is attached to the flat portion 24 of the pressure receiving member 20 (see Figure 5). By doing so, the second engagement portion 52 acts to pull up one end of the harness movement suppression member 50, which is positioned closer to the electrical component 30, towards a higher position, making it easier to suppress the downward movement of the harness 40 connected to the electrical component 30.

[0045] Furthermore, the width of the harness movement suppression member 50, which is a sheet-like member, on one end where the second engagement portion 52 is provided is wider than the width of the harness movement suppression member 50, which is a sheet-like member, on the other end where the first engagement portion 51 is provided. In this way, by widening the width of one end of the harness movement suppression member 50, which is provided with a second engagement portion 52 that engages with the bracket 31 of the electrical component 30, and by widening the width of one end of the harness movement suppression member 50 that is positioned closer to the electrical component 30, the harness 40 connected to the electrical component 30 can be supported over a wide range, and it becomes easier to suppress the downward movement of the harness 40 connected to the electrical component 30.

[0046] As described above, the vehicle seat S of this embodiment is equipped with a harness movement suppression member 50 that prevents the harness 40 connected to the electrical component 30 from moving downward. Therefore, even if the harness 40 becomes loose and hangs down, the harness movement suppression member 50 can support the harness 40 from below, and the harness 40 will not move below the harness movement suppression member 50. With this type of vehicle seat S, even if the harness 40 becomes loose and hangs down, it is possible to prevent the harness 40 from moving below the harness movement suppression member 50, thereby reducing the risk of the harness 40 coming into contact with the vehicle floor or other surfaces and being damaged.

[0047] In particular, this vehicle seat S uses a harness movement suppression member 50 which is a sheet-like member, and a second engagement portion 52 which is a hook-shaped member is provided at one end of the harness movement suppression member 50, and a first engagement portion 51 which is an elastic band member is provided at the other end. This relatively simple configuration makes it possible to support the harness 40 arranged in the vehicle seat S.

[0048] Furthermore, the harness movement suppression member 50 is relatively compact in size, capable of covering about half of one side of the pressure receiving member 20, making it easy to handle and facilitating installation on the vehicle seat S. Specifically, since the harness movement suppression member 50 is smaller compared to one that covers the entire width of the cushion frame 1, weight reduction and cost savings can be achieved. Furthermore, it minimizes interference with the placement of other components, improving design flexibility. In addition, installation becomes easier. Furthermore, since the harness movement suppression member 50 is positioned biased toward the installation location of the electrical component 30 to which the harness 40 is wired, the harness 40 can be supported efficiently while keeping the size of the harness movement suppression member 50 to a minimum.

[0049] Here, we will explain the procedure for installing the harness movement suppression member 50 on the vehicle seat S in order to support the harness 40 that is arranged on the vehicle seat S with the harness movement suppression member 50. First, the harness movement suppression member 50 is inserted from the front of the vehicle seat S under the seat cushion S1, and the hook-shaped member (first engagement portion 51) provided at the other end of the harness movement suppression member 50 is engaged with the engagement hole 24h formed in the flat portion 24 of the pressure receiving member 20. Furthermore, since the engagement hole 24h is formed in a flat portion 24 that includes a flat area, the hook-shaped member (first engagement portion 51) can be easily engaged with the engagement hole 24h. For example, if the engagement hole 24h is formed on a surface that has many irregularities or large undulations, the position of the hook-shaped member (first engagement portion 51) engaged with the engagement hole 24h may not be stable, which is undesirable.

[0050] Next, with the hook-shaped member (first engagement portion 51) engaged with the engagement hole 24h, the harness movement suppression member 50 is pulled toward the front of the vehicle seat S, and the band member (second engagement portion 52) provided at one end of the harness movement suppression member 50 is pulled to engage the band member (second engagement portion 52) with the hook portion 31a provided on the bracket 31 of the electrical component 30. Furthermore, since the band member (second engagement portion 52) is elastic, it can be easily attached to the hook portion 31a of the bracket 31 by stretching and then contracting the band member. Furthermore, the contraction of the band member (second engagement portion 52) causes one end of the harness movement suppression member 50 to be pulled up towards the bracket 31 of the electrical component 30.

[0051] By following these steps, the harness movement suppression member 50 can be installed on the underside of the vehicle seat S, and the harness 40 arranged on the vehicle seat S can be supported from below by the harness movement suppression member 50. Furthermore, with such a harness movement suppression member 50, the harness movement suppression member 50 can be easily installed on the underside of the vehicle seat S by attaching the hook-shaped member (first attachment portion 51) to the attachment hole 24h and the band member (second attachment portion 52) to the hook portion 31a.

[0052] Furthermore, since one end of the harness movement suppression member 50 is raised towards the bracket 31 of the electrical component 30, the downward movement of the harness 40 connected to the electrical component 30 can be effectively suppressed. Furthermore, since the width of one end of the harness movement suppression member 50, which is positioned closer to the electrical component 30, is relatively wide, the harness 40 connected to the electrical component 30 can be broadly supported by the harness movement suppression member 50, and the downward movement of the harness 40 can be effectively suppressed.

[0053] Thus, with the vehicle seat S of this embodiment, the harness movement suppression member 50 can effectively suppress the downward movement of the harness 40 connected to the electrical component 30.

[0054] The application of the present invention is not limited to the embodiments described above, and can be modified as appropriate without departing from the spirit of the invention. [Explanation of Symbols]
