Summary of the Invention

Problems to be Solved by the Invention

[0005] By the way, in a vehicle seat such as that of Patent Document 1, it has been required to suitably hold a harness for connecting an electrical device or the like inside the seat. For example, when housing a harness in a housing groove formed on the surface of a pad material, it has been required to prevent the harness from accidentally coming out of the housing groove or being displaced within the housing groove.

[0006] Furthermore, when the seat body (seat cushion) has two different pad materials, and the harness is to be housed in a receiving groove formed on the surface of the pad material, it was required to adequately hold the harness while ensuring the seating feeling of the occupant.

[0007] The present invention has been made in view of the above problems, and the object of the present invention is to provide a vehicle seat that can more favorably hold connecting members for connecting electrical devices and the like inside the seat body than in the conventional invention. Another object of the present invention is to provide a vehicle seat that can suitably hold connecting members while ensuring a comfortable seating feel. [Means for solving the problem]

[0008] The aforementioned problems are solved by the vehicle seat of the present invention, which is a vehicle seat equipped with a pad material, comprising a connecting member provided inside the vehicle seat for connecting an electrical device, wherein the pad material comprises a first pad material and a second pad material provided on the back side of the first pad material and arranged to overlap the first pad material, wherein a accommodating groove is formed on the surface or back surface of at least one of the first pad material so as to be recessed in the thickness direction of the pad material for accommodating the connecting member, the accommodating groove extends elongated along the surface of at least one of the pad material, is provided at a predetermined position in the extension direction of the accommodating groove, and has a hooking portion that protrudes from one side to the other side of the accommodating groove for accommodating the connecting member. With the above configuration, it is possible to realize a vehicle seat that can more effectively hold connecting members for connecting electrical devices inside the seat body than in conventional designs. More specifically, the receiving groove formed on the surface of the pad material has a retaining portion that protrudes from one side of the receiving groove toward the other side, securing the connecting member. Therefore, it is possible to prevent the connecting member from unintentionally coming out of the receiving groove or from shifting position within the receiving groove.

[0009] In this case, a recess that is recessed in the thickness direction of the pad material or a through hole that penetrates through the pad material is formed in a part of the bottom surface of the receiving groove, and the fastening portion is provided at a position corresponding to the recess or the through hole in the extending direction of the receiving groove, and is fastened so as to cover the connecting member. Furthermore, it is preferable that the recess or through hole is formed to protrude from the receiving groove toward the other side of the receiving groove, and that the portion of the recess or through hole formed on the bottom surface of the receiving groove is positioned to face the latching portion, and that the portion of the recess or through hole protruding from the receiving groove is positioned not to face the latching portion. Furthermore, it is preferable that the portion formed on the bottom surface of the receiving groove in the recess or the through hole extends to a position outside the ends of the latching portion in the extending direction of the receiving groove. The above configuration allows for easy assembly of connecting members to the latching portion formed in the receiving groove, despite its simple structure. More specifically, guide portions (recesses and through holes) for assembling connecting members are formed around the latching portion. Therefore, the structure facilitates the assembly of connecting members. Furthermore, with the above configuration, the latching portion latches onto the connecting member so as to cover it, which further prevents the connecting member from unintentionally coming out of the housing groove.

[0010] In this case, it is preferable that the second pad material is formed to be harder than the first pad material, and that the receiving groove is formed on the surface of the second pad material and is provided facing the back surface of the first pad material. The above configuration provides a vehicle seat that can securely hold the connecting members while ensuring a comfortable seating feel. More specifically, because the connecting member is attached to the second pad material (the vehicle-side pad material) rather than the first pad material (the seater-side pad material), the seater's seating feel can be ensured. Furthermore, because the connecting member is attached to the surface of the second pad material, which is harder than the first pad material, the connecting member can be suitably held in place by the harder second pad material.

[0011] In this case, it is preferable that a detection sensor is provided to detect the biological signals of the seated person, and that the surface of the second pad material has a housing groove and a sensor housing portion for housing the detection sensor, with one end of the connecting member connected to the detection sensor and the other end of the connecting member exposed from the second pad material and connected to the electrical device side. With the above configuration, a seat body having two pad materials with different hardness levels can be configured to enhance the sensing sensitivity of the detection sensor while ensuring a comfortable seating experience for the occupant. More specifically, because the detection sensor is positioned on the surface of the second pad material, which has high hardness, the detection sensor can effectively detect the occupant's biological signals.

[0012] In this case, the receiving groove and the sensor receiving portion are formed continuously on the surface of the second pad material, the sensor receiving portion is formed in multiple locations spaced apart in the sheet width direction, the receiving groove has a groove body portion that extends elongated in the sheet width direction, and multiple groove extension portions formed at intervals in the sheet width direction, each extending in the front-rear direction of the sheet and connecting the groove body portion and the sensor receiving portion, and the fastening portion is formed in multiple locations spaced apart in the sheet width direction and is preferably arranged between the multiple sensor receiving portions in the sheet width direction. As described above, the device is equipped with multiple latching points, allowing it to effectively hold the connecting member and the detection sensor.

[0013] In this case, the groove body extends to one end of the second pad material in the sheet width direction, and the other end of the connecting member is exposed from the one end of the second pad material and connected to the electrical device side. As described above, by extending the connecting member in the width direction of the sheet body inside the sheet and exposing it from one end in the width direction of the sheet, interference between the connecting member and other components can be suppressed, resulting in a simple arrangement pattern.

[0014] In this case, the device is equipped with a wire member for holding the second pad material, and the second pad material is preferably made of foamed resin and the wire member is insert-molded into it. The above configuration improves the rigidity of the second pad material. Furthermore, the second pad material can firmly hold the wire member.

[0015] In this case, it is preferable that the second pad material is made of expanded polypropylene, and the first pad material is made of urethane foam and placed on top of the second pad material. As described above, by using urethane foam for the first pad material on the side closer to the occupant, the seating comfort of a vehicle seat can be improved. [Effects of the Invention]

[0016] According to the present invention, it is possible to realize a vehicle seat that can more effectively hold connecting members for connecting electrical devices inside the seat body than in conventional designs. In other words, it is possible to suppress the connecting members from unintentionally coming out of the housing groove or from shifting position within the housing groove. Furthermore, according to the present invention, despite its simple structure, the connecting member can be easily assembled to the latching portion formed in the housing groove. Furthermore, according to the present invention, the connecting member can be suitably held while ensuring a comfortable seating feel. Furthermore, according to the present invention, the connecting member and the detection sensor can be held appropriately, and the sensing sensitivity of the detection sensor can be increased. According to the present invention, interference between the connection member and other components can be suppressed, and a simple layout pattern can be achieved. According to the present invention, the rigidity of the second pad material can be improved. Further, the wire member can be firmly held by the second pad material.

Embodiments for Carrying Out the Invention

[0018] Hereinafter, embodiments according to the present invention will be described with reference to FIGS. 1 to 7. This embodiment includes a connection member for connecting an electrical device inside the seat body. The pad material of the seat body has a first pad material and a second pad material. On the surface of the second pad material, a receiving groove for accommodating the connection member is formed. The receiving groove protrudes from one side portion to the other side portion of the receiving groove in order to accommodate the connection member and has a latching portion for latching the connection member. This is the invention of a vehicle seat mainly characterized by this. Note that the side where the seated person sits with respect to the seat back of the vehicle seat is the front side of the seat.

[0019] As shown in Figure 1, the vehicle seat S of this embodiment is a vehicle seat, and is, for example, a rear vehicle seat corresponding to the rear seat of an automobile. As shown in Figures 1, 4, and 7, the vehicle seat S mainly consists of a seat body having a seat cushion 1, a seat back 2, and a headrest 3; a seat-shaped detection sensor 40 attached inside the seat body to detect whether a person is seated in the seat; a connecting member 50 electrically connected to the detection sensor 40; and a control device 60 that receives signals detected by the detection sensor 40 via the connecting member 50 and processes them based on those signals.

[0020] As shown in Figures 1 to 3, the seat cushion 1 is a seating portion that supports the occupant from below, and is constructed by covering the pad material 10, which is the main body of the seat cushion 1, with a surface material 1a. As shown in Figure 1, the seat back 2 is a backrest that supports the seated person's back from behind, and is constructed by covering a pad material 2a with a surface material 2b. The seat cushion 1 is attached to the vehicle body (vehicle frame) via the wire member 13 shown in Figure 3. The seat back 2 is attached to the vehicle body via a vehicle body connecting member (not shown). In this way, the seat body is assembled to the vehicle body.

[0021] As shown in Figures 2 to 4, the pad material 10 is a pad laminate formed by stacking multiple pad materials vertically, and comprises a first pad material 11 positioned on the upper side (seater side) and a second pad material 12 that is formed harder than the first pad material 11 and positioned on the lower side (vehicle body side). The first pad material 11 is attached to the upper surface of the second pad material 12, and is attached so as to cover the second pad material from above. More specifically, when the first pad material 11 and the second pad material 12 are assembled, the first pad material 11 abuts against substantially the entire top surface, front surface, and both sides of the second pad material 12, and also abuts against a part of the rear surface of the second pad material 12. Furthermore, when the first pad material 11 and the second pad material 12 are assembled, a portion of the rear part of the second pad material 12 (the anchor-through portion 12c) is exposed upward.

[0022] As shown in Figure 2, the first pad material 11 is formed from a resin material such as urethane foam. The surface of the first pad material 11 has a first surface suspension groove 11a and a second surface suspension groove 11b formed therein for suspending the surface material 1a. The first surface suspension groove 11a is a longitudinal suspension groove formed at intervals in the sheet width direction and extending in the front-to-back direction of the sheet. The second surface suspension groove 11b is a transverse suspension groove formed on the surface of the first pad material 11 in the approximate center of the sheet in the front-rear direction and extending in the sheet width direction. The second epidermal suspension groove 11b connects to the adjacent first epidermal suspension groove 11a.

[0023] The rear end of the first pad material 11 is provided with multiple hook-shaped attachment portions 11c, spaced apart in the width direction of the sheet, for attachment to attachment portions 12b provided on the second pad material 12, and openings 11d are positioned between adjacent attachment portions 11c. The anchor-through portion 12c of the second pad material 12 is exposed upward through the opening 11d.

[0024] In the above configuration, as shown in Figure 2, the first skin suspension groove 11a and the second skin suspension groove 11b and the detection sensor 40 are arranged in different positions (non-overlapping positions) when viewed from above. By positioning the detection sensor 40 in a location that avoids being directly below the surface suspension grooves 11a and 11b, the detection performance of the detection sensor 40 in response to seating pressure can be improved. Furthermore, in a top view, the first skin suspension groove 11a and the second skin suspension groove 11b and the connecting member 50 are positioned as far apart as possible (not overlapping). In other words, the connecting member 50 is positioned to overlap with the main body portion of the first pad material 11. By doing so, it is possible to further suppress the possibility of the connecting member 50 unintentionally coming loose or becoming misaligned.

[0025] As shown in Figures 2 to 4, the second pad material 12 is formed from a resin material such as foamed polypropylene, and has a wire member 13 inserted into it. The second pad material 12 is provided on the back side of the first pad material 11 and is positioned to overlap the first pad material 11 in the vertical direction.

[0026] The surface of the second pad material 12 is provided with a sensor housing recess 12a for housing a detection sensor 40, which is recessed in the thickness direction of the pad material 10, and a housing groove 20 for housing a connecting member 50, which is provided continuously with the sensor housing recess 12a. Furthermore, the rear end of the second pad material 12 is provided with multiple convex mounting portions 12b, which are spaced apart in the sheet width direction and are for attachment to the mounting portion 11c of the first pad material 11, and anchor passing portions 12c, which are positioned between adjacent mounting portions 11c. The anchor through-hole 12c is a through-hole for passing an anchor member (extension member) not shown, and specifically, it is a through-hole for passing an anchor member for connecting a child seat. The anchor member is attached to the vehicle body and assembled so that it protrudes forward from the seat body, passing through the anchor passage 12c from the vehicle body.

[0027] As shown in Figure 3, the wire member 13 is a vehicle body assembly member for assembling the vehicle seat S to the vehicle body, and is fixed inside the front portion of the seat cushion 1. More specifically, the wire member 13 is molded (insert molded) together with the second pad material 12 and fixed inside the second pad material 12.

[0028] The wire member 13 is provided inside the second pad material 12 and has a wire body portion 13a that extends elongated in the sheet width direction, and left and right wire assembly portions 13b formed at both ends of the wire body portion 13a, protruding downward from the wire body portion 13a and exposed to the outside from the second pad material 12. The left and right wire assembly sections 13b are assembled to assembly sections provided on the vehicle body (vehicle frame), which is not shown. Furthermore, a vehicle body connecting member (not shown) is fixed to the seat back 2 (pad material 2a) for connecting to a connecting portion provided on the vehicle body. With the above configuration, the seat body is assembled to the vehicle body.

[0029] As shown in Figures 4 to 6, the accommodating groove 20 is a groove for accommodating the connecting member 50, and is formed on the surface of the second pad material 12 and is provided facing the back surface of the first pad material 11. The receiving groove 20 is formed on the surface of the second pad material 12, but is not particularly limited and may be formed on the back surface of the second pad material 12. Alternatively, it may be formed on the back surface of the first pad material 11, or on the surface of the first pad material 11.

[0030] The accommodating groove 20 comprises a groove body portion 21 that extends elongated in the sheet width direction, and a plurality of groove extension portions 22 that are formed at intervals in the sheet width direction and each extends forward from the groove body portion 21 to the sheet. A hooking portion 30 for hooking a connecting member is formed at a predetermined position in the extending direction of the groove body portion 21.

[0031] The groove body portion 21 extends from a lateral position (left side position) in the sheet width direction of the second pad material 12 to one end (right side end) in the sheet width direction. More specifically, the groove body 21 extends in a meandering manner, corresponding to the position of the detection sensor 40 located on the surface of the second pad material 12, and avoiding holes (recesses) formed on the surface of the second pad material 12. These holes (recesses) are, for example, fitting holes (fitting recesses) that fit into mounting protrusions provided on the bottom surface of the first pad material 11. Alternatively, they are guide holes (guide recesses) for routing connecting members (harnesses) other than the connecting member 50.

[0032] The groove extension 22 connects the groove body 21 and the sensor housing recess 12a. Multiple sensor housing recesses 12a are formed, specifically at the central position in the sheet width direction, the left-side position, and the right-side position. The groove extensions 22 are formed at the center, left-side, and right-side positions in the sheet width direction, corresponding to each sensor housing recess 12a.

[0033] As shown in Figures 4 to 6, the latching portions 30 are used to latch the connecting member 50, and multiple latching portions are formed at intervals in the extending direction of the housing groove 20. More specifically, the fastening portion 30 is positioned between a plurality of sensor housing recesses 12a in the sheet width direction.

[0034] As shown in Figures 5 and 6, the latching portion 30 is provided with a projection 31 that protrudes from one side 21a toward the other side 21b of the housing groove 20 (groove body portion 21) in order to accommodate the connecting member 50. Furthermore, the latching portion 30 is provided on the bottom surface of the groove body portion 21 at a position corresponding to the projection portion 31 (directly below), and includes a recess 32 formed to be recessed downward, and a through hole 33 formed on the bottom surface of the recess 32 that penetrates in the vertical direction.

[0035] The projection 31 protrudes rearward from the upper portion of the side portion 21a located on the front side of the groove body portion 21 toward the side portion 21b located on the rear side of the groove body portion 21. More specifically, as shown in Figure 6, the projection 31 protrudes further rearward from the groove body 21. Therefore, the projection 31 covers the connecting member 50 housed in the housing groove 20 from above, and the connecting member 50 can be securely hooked in place. The projection 31 may also be one that protrudes forward from the side portion 21b toward the side portion 21a of the groove body portion 21.

[0036] The recess 32 is a depression having an inner surface that slopes inward from the upper side to the lower side. In other words, the recess 32 is a depression with an inverse tapered shape. The recess 32 is provided below (directly below) the projection 31, and is formed to be wider than the projection 31 in the sheet width direction, and longer than the projection 31 in the sheet front-to-back direction. More specifically, the recess 32 is formed to protrude further rearward from the seat than the projection 31.

[0037] The through hole 33 is a rectangular hole formed in the bottom surface of the recess 32. The through-hole 33 is located directly below the projection 31 and is formed to have approximately the same width as the projection 31 in the sheet width direction. It is also formed to protrude further rearward than the projection 31. By forming the through hole 33, it is possible to visually confirm, for example, that the connecting member 50 is hooked onto the hooking portion 30 (projection portion 31) using the through hole 33.

[0038] In the above configuration, as shown in Figure 4, the projection 31 protrudes toward the rear of the seat from the side portion 21a located on the front side of the groove body portion 21. The recess 32 is formed to protrude toward the rear of the seat from the groove body portion 21. In other words, the projection 31 and recess 32 protrude from the groove body 21 toward the rear of the seat, while the groove extension 22 protrudes toward the front of the seat. By doing so, the groove body portion 21, the groove extension portion 22, the projection portion 31, and the recess portion 32 can be arranged in a balanced manner on the surface of the second pad material 12. In other words, they can be arranged on the surface of the second pad material in a way that minimizes interference with other components.

[0039] In the above configuration, as shown in Figure 5, the recess 32 is formed to protrude from the accommodating groove 20 toward the side portion 21b of the accommodating groove 20. Furthermore, the portion formed on the bottom surface of the receiving groove 20 in the recess 32 is positioned to face the latching portion 30. Also, the portion protruding from the receiving groove 20 in the recess 32 is positioned so as not to face the latching portion 30. By doing so, the connecting member 50 can be easily assembled to the latching portion 30 formed in the receiving groove 20, despite the simple structure. More specifically, a guide portion (recess 32) for assembling the connecting member 50 is formed around the latch portion 30. Therefore, the structure is designed to facilitate the assembly of the connecting member 50.

[0040] In the above configuration, as shown in Figure 5, the portion formed on the bottom surface of the receiving groove 20 in the recess 32 extends to a position outside the ends of the latching portion 30 in the extending direction of the receiving groove 20. By doing so, the recess 32 acts as a guide, making it easier to assemble the connecting member 50 to the latching portion 30.

[0041] As shown in Figures 4 and 7, the detection sensor 40 is a sheet-shaped pressure sensor that detects the seating pressure applied to the seating surface of the seat cushion 1 when a person sits on the seat, and is attached to the surface of the second pad material 12. Here, "seating pressure" refers to a value that changes periodically in accordance with the physiological activity of a person sitting on the seat cushion 1, specifically breathing, and is the target value detected by the pressure sensor. The detection sensor 40 is preferably a seat sensor that turns on or off in response to the seating pressure of the person sitting. Preferably, it is a push-switch type seat sensor.

[0042] Multiple detection sensors 40 are provided at intervals in the sheet width direction, and each is housed in a sensor housing recess 12a of the second pad material 12, positioned so as not to protrude from the second pad material 12 as much as possible. Each detection sensor 40 is positioned at or near the hip point of the seated person. Each sensor independently detects the seating pressure and outputs a detection signal based on the detected seating pressure.

[0043] As shown in Figure 4, the detection sensor 40 includes a sensor detection unit 41 for detecting the seating pressure applied by a seated person, and a transmission line 42 for outputting a detection signal when the sensor detection unit 41 detects the seating pressure. The sensor detection unit 41 is a pressure-sensitive switch that is bonded to the conductive sheet. The transmission line 42 is formed by bonding conductive wires, which serve as the transmission line, to a conductive sheet. The transmission line 42 extends from the sensor detection unit 41 to the rear of the seat and is electrically connected to the connecting member 50.

[0044] As shown in Figures 4 to 7, the connecting member 50 is a wire harness formed by bundling conductive wires and is housed in the housing groove 20. The connecting member 50 extends to be elongated in the sheet width direction and connects the detection sensor 40 and the control device 60. More specifically, one end of the connecting member 50 is connected to the detection sensor 40, and the other end is exposed from the second pad material 12 and connected to the control device 60.

[0045] Specifically, the connecting member 50 comprises a main body portion 51 that extends lengthwise in the sheet width direction, multiple extension portions 52 formed at intervals in the sheet width direction and extending forward from the main body portion 51, and a coupler 53 provided at the other end (right end) of the main body portion 51 for connecting to the control device 60.

[0046] As shown in Figure 7, the control device 60 is a device that processes biological signals detected by the detection sensor 40, and is installed inside the vehicle seat S. The control device 60 includes a communication unit 61 for receiving biological signals detected by the detection sensor 40 and transmitting them wirelessly to the outside, and a control unit 62 for processing the transmission of biological signals detected by the detection sensor 40 to the communication unit 61.

[0047] The communication unit 61 uses wireless communication technology to connect to external terminals, such as tablet devices, smartphones, PCs, and other computers and electrical equipment, and to send and receive electrical signals (data signals). The control unit 62 is equivalent to a microcomputer and comprehensively performs electrical control. The control device 60 is designed to receive power from a power source P installed inside the vehicle. The control device 60 may be installed inside the vehicle seat S, or it may be installed outside the vehicle seat S.

[0048] In the above configuration, the control device 60 is connected via a network to safety devices such as a seat belt device (not shown) and a movable device that moves part or all of the seat body, and transmits operating signals to these devices. For example, it controls the device to notify the seated person to fasten their seat belt, or to activate the movable device.

[0049] <Other embodiments> In the above embodiment, as shown in Figure 2, the pad material 10 was constructed by laminating a first pad material 11 and a second pad material 12, but it is not particularly limited. For example, the pad material 10 may be composed of three or more pad materials stacked together. In that case, it is preferable that the first pad material, which is located closest to the seated person, is relatively soft, and the second and subsequent pad materials are harder than the first pad material. In that case, it is also preferable that the detection sensor 40 be attached to the surface or back surface of the relatively hard second or third pad material.

[0050] In the above embodiment, as shown in Figure 2, the receiving groove 20 (groove body portion 21) extends to be elongated in the sheet width direction, but this is not particularly limited. For example, the storage groove 20 may extend in the front-to-back direction of the seat, or it may extend so as to intersect (incline) with the front-to-back direction of the seat.

[0051] In the above embodiment, as shown in Figure 4, the accommodating groove 20 is provided on the surface of the second pad material 12 at a position behind each detection sensor 40 on the sheet and extends to be elongated in the sheet width direction, but this is not particularly limited. For example, the storage groove 20 may be positioned in front of each detection sensor 40 on the seat. For example, if the detection sensors 40 are arranged in a line in the front-to-back direction of the sheet, the storage groove 20 may be positioned outside the detection sensors 40 in the sheet width direction.

[0052] In the above embodiment, as shown in Figure 4, the detection sensor 40 was a pressure sensor, but it is not particularly limited and can be changed to any sensor that detects a target value that changes when a person sits on the seat. For example, the detection sensor 40 may be a shape sensor that detects a value corresponding to the skeletal shape of the seated person (the skeletal shape of the part of the seated person's body that is in contact with the seat), or it may be a potential sensor that detects the body potential of the seated person.

[0053] In the above embodiment, as shown in Figure 4, the detection sensor 40 is mounted inside the seat cushion 1, but it is not particularly limited and may also be mounted inside the seat back 2. In that case, the detection sensor 40 is preferably attached to the surface or back surface of the pad material 2a of the seat back 2. Preferably, it is attached to the surface (front surface) of the second pad material located on the rear side of the seat in a plurality of pad materials 2a stacked in the front-rear direction of the seat.

[0054] In the above embodiment, as shown in Figure 5, a recess 32 is formed as a guide portion to facilitate the fastening portion 30 (projection portion 31) with the connecting member 50, but this is not particularly limited. In other words, the guide portion may have a recess or a through hole. Of course, both a recess and a through hole may be formed.

[0055] In the above embodiment, as shown in Figure 7, the connecting member 50 connects the detection sensor 40 and the control device 60, but this is not particularly limited. In other words, the connecting member 50 may connect the first electrical device (electrical component) and the second electrical device (electrical component).

[0056] In the above embodiment, a vehicle seat used in an automobile was described as a specific example, but it is not particularly limited and can be used for various types of seats, including motorcycle seats, seats in trains and buses, seats in airplanes and ships, as well as office chairs for work, wheelchairs, and children's seats in shopping carts.

[0057] In this embodiment, the vehicle seat according to the present invention was described primarily. However, the embodiments described above are merely examples to facilitate understanding of the present invention and do not limit it.
