Summary of the Invention
Problems to be Solved by the Invention
[0004] By the way, a harness connected to an automotive seat is required to adjust the length of the stored harness as the automotive seat is displaced. For this reason, there is a region (for example, a harness case) where the excess length portion of the harness is stored, and there is a demand to suppress intrusion of foreign matter into this region.
[0005] One aspect of the present disclosure is to suppress intrusion of foreign matter into a region where an excess length portion of a harness is stored in an automotive seat mounted in a vehicle.
Means for Solving the Problems
[0006] One aspect of the present disclosure is an automobile seat (1) to be mounted in an automobile, comprising a movable part (2), a harness (3), a fastener (41), and a retaining part (4). The movable part (2) includes a seat body (20) having at least a seat cushion (21), and slides with respect to the automobile together with the seat body (20). The harness (3) is directly or indirectly connected to electrical equipment provided on the movable part (2), with one end fixed to the movable part (2) and the other end fixed to the automobile. The fastener (41) extends along the longitudinal direction of the seat. The retaining part (4) is fixed to the automobile and has an opening (40) extending along the longitudinal direction of the seat, and holds the fastener (41). The fastener (41) opens and closes the opening (40). The harness (3) passes through the opening (40) and is displaced along the longitudinal direction of the seat.
[0007] With this configuration, the harness (3) is displaced along the longitudinal direction of the sheet, so that the excess portion of the harness (3) can be stored on the side opposite the sheet body (20) across the opening (40). In this configuration, the fastener (41) closes at least a part of the opening (40) provided in the holding part (4), that is, the opening (40) between the sheet body (20) and the area where the excess portion of the harness (3) is stored. Therefore, the entry of foreign matter into the area where the excess portion of the harness (3) is stored can be suppressed.
[0008] One aspect of the present disclosure is a harness slider (42) positioned in the opening (40) and displaced together with the harness (3), which may further comprise a cylindrical harness slider (42) with both ends positioned on either side of the holding portion (4). The harness (3) may pass through the opening (40) by passing through the inside of the harness slider (42).
[0009] With this configuration, the harness (3) contacts the holding part (4) via the harness slider (42), so the opening (40) can be displaced without direct contact with the holding part (4). Therefore, the load on the harness (3) during the displacement of the harness (3) can be suppressed, and the lifespan of the harness (3) can be extended.
[0010] One aspect of the present disclosure may further include two fastener sliders (43) attached to the fastener (41) for opening and closing the fastener (41). The two fastener sliders (43) may be mounted facing each other along the longitudinal direction of the sheet, sandwiching a harness slider (42). The harness slider (42) may be connected to the two fastener sliders (43).
[0011] With this configuration, the two fastener sliders (43) open the fasteners (41) in the area where the harness slider (42) is positioned, and displace the opening (40) provided in the holding part (4) together with the harness slider (42). Therefore, the displacement of the harness (3) and harness slider (42) is made smooth, while preventing foreign matter from entering the area where the excess length of the harness (3) is stored.
[0012] In one aspect of the present disclosure, the harness slider (42) may further have a locking portion (42C) configured to secure two fastener sliders (43). With this configuration, the harness slider (42) that covers the harness (3) and the fastener slider (43) that opens and closes the fastener (41) can be manufactured as separate components. Therefore, they can be easily assembled. Furthermore, this configuration prevents the two fastener sliders (43) from moving away from the harness slider (42). Therefore, it is possible to prevent the fasteners (41) in areas where the harness (3) and harness slider (42) are not located from opening, and to prevent foreign objects from entering the area where the excess length of the harness (3) is stored.
[0013] One aspect of the present disclosure may further include a fastener housing (46) configured to house a fastener (41). The fastener (41) may be configured to be housed in the fastener housing (46) when the fastener (41) is opened.
[0014] With this configuration, interference between the fastener (41), which is open in the area where the harness (3) and harness slider (42) are positioned, and the harness (3) and harness slider (42) can be suppressed. Therefore, the harness (3) and harness slider (42) can be smoothly displaced along the opening (40) provided in the holding part (4).
[0015] In one aspect of the present disclosure, the movable part (2) may further have a protruding part (23A) that protrudes toward the holding part (4). The harness slider (42) may further have a connecting part (47) that is connected to the protruding part (23A).
[0016] With this configuration, the harness slider (42) is connected to the protruding part (23A) and therefore displaces integrally with the movable part (2). In other words, since the harness (3) is displaced by displacing the harness slider (42), the harness (3) can be displaced without applying excessive force to the harness (3). As a result, the load on the harness (3) during its displacement can be suppressed, and the lifespan of the harness (3) can be extended.
[0017] In one aspect of the present disclosure, the holding portion (4) may further have an end cap (45) at the end of the opening (40). The connecting portion (47) may have a mounting portion (47A), a first support portion (47B), and a second support portion (47C). The mounting portion (47A) is configured on which the protrusion (23A) is mounted. The first support portion (47B) and the second support portion (47C) are configured to support the protrusion (23A) by sandwiching it from the sides. When the protrusion (23A) moves along the longitudinal direction of the sheet and the harness slider (42) reaches the end, the first support portion (47B) may be configured to transition to a state where it does not support the sides of the protrusion (23A) by being pressed downward by the end cap (45). As the protrusion (23A) moves further along the longitudinal direction of the sheet, the protrusion (23A) may be configured to move away from the mounting portion (47A) and beyond the end cap (45).
[0018] According to such a configuration, when the harness slider (42) reaches the end of the opening (40), the protruding portion (23A) moves away from the placement portion (47A) and is not supported by the first support portion (47B) and the second support portion (47C). That is, the connection between the protruding portion (23A) and the connecting portion (47) is released, and the protruding portion (23A) moves to a position beyond the end cap (45). Thereby, the movable portion 2 can adopt a configuration in which it slides a longer distance beyond the range in which the harness slider (42) can be displaced.

Embodiments for Carrying Out the Invention
[0020] Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. The following "Embodiments of the Invention" are examples of embodiments that fall within the technical scope of this disclosure. In other words, the features defining the invention as described in the claims are not limited to the specific configurations and structures shown in the embodiments below.
[0021] [1. Embodiments] [1-1. Structure] The automotive seat 1 shown in Figure 1 is a seat mounted in an automobile and has a sliding function relative to the automobile. The automotive seat 1 comprises a movable part 2, a harness 3, a holding part 4, and a fastener 41 (see, for example, Figure 2). The automotive seat 1 may further comprise at least one of the following: a harness case 6, a slide rail 24, a harness slider 42 (see, for example, Figure 2), and a fastener slider 43 (see, for example, Figure 4B).
[0022] The movable part 2 is a part that slides relative to the vehicle together with the seat body 20. In this embodiment, the movable part 2 is displaced in the front-rear direction of the vehicle. The movable part 2 comprises the seat body 20 and the cushion frame 23.
[0023] The seat body 20 is the part that supports the occupant when they sit in the vehicle. The seat body 20 comprises a seat cushion 21 and a seat back 22. The seat cushion 21 is the part that supports the occupant's lower body. The seat back 22 is the part that supports the occupant's upper body.
[0024] The cushion frame 23 is positioned below the seat body 20 and is a member that supports the seat body 20. At least a portion of the cushion frame 23 is positioned within the slide rail 24 and is configured to slide along the slide rail 24. The slide rail 24 is fixed to the vehicle (for example, a part of the vehicle body 50, particularly the floor material 51 in the vehicle's passenger compartment (see Figure 6)) at the point where the cushion frame 23 is positioned.
[0025] For example, the cushion frame 23 may be configured to slide by a roller provided at the bottom of the cushion frame 23 rolling within the slide rail 24. Therefore, the movable part 2 is configured to slide relative to the automobile.
[0026] In this embodiment, the automobile seat 1 comprises two cushion frames 23 and two slide rails 24. The two cushion frames 23 support the seat body 20 at both ends in the seat width direction. The two slide rails 24 are arranged parallel to each other so that their longitudinal direction aligns with the front-to-rear direction of the automobile. The cushion frame 23 may have a protruding portion 23A. The protruding portion 23A is a part that protrudes toward the holding portion 4, as shown in Figure 5A.
[0027] The harness 3 is electrical wiring for electrically connecting the electrical equipment installed on the movable part 2 to the automobile. For example, the harness 3 may include power lines connecting a motor for driving the electric seat, a seat heater, etc., to a power source such as the automobile's battery, and signal lines for controlling the electric seat. These power lines and signal lines are each insulated. One end of the harness 3 is fixed to the movable part 2, and the other end is fixed to the automobile. Here, the other end of the harness 3 may be fixed to any part of the automobile. For example, the other end of the harness 3 may be fixed to a part of the automobile body 50, or it may be fixed to the slide rail 24. The harness 3 is flexible and can be easily deformed. The harness 3 is protected by being covered with a flexible corrugated tube (not shown).
[0028] The retaining part 4 is a member that holds the fastener 41. The retaining part 4 is positioned adjacent to one of the two slide rails 24 and parallel to the slide rail 24. The retaining part 4 is positioned between the two slide rails 24. The retaining part 4 is fixed to the automobile. As shown in Figures 4A and 6, the retaining part 4 has an opening 40 that extends in the longitudinal direction of the seat. Here, the longitudinal direction of the seat refers to the direction in which the movable part 2 slides. In other words, in this embodiment, the longitudinal direction of the seat refers to the front-rear direction of the automobile. The retaining part 4 has an end cap 45. As shown in Figures 5A and 5B, the end cap 45 is formed at the end of the opening 40.
[0029] The fastener 41 is a component that opens and closes the opening 40. The fastener 41 extends in the longitudinal direction of the sheet and is attached so as to close at least a portion of the opening 40. In this embodiment, the fastener 41 is attached to the lower surface of the holding portion 4. Any fastener 41 can be used, such as a wire fastener or a hook fastener.
[0030] The harness slider 42 shown in Figures 4A and 4B is a member that slides against the holding part 4 and displaces the holding part 4. The harness slider 42 in this embodiment is formed from an upper slider 42A and a lower slider 42B. The upper slider 42A is a member that covers the harness 3 from above. The lower slider 42B is a member that covers the harness 3 from below. As a result, the harness slider 42 can be easily assembled without damaging the harness 3.
[0031] The harness slider 42 is positioned so that both vertical ends sandwich the holding portion 4. The harness slider 42 is formed in a cylindrical shape, and the harness 3 is configured to pass through the inside of the harness slider 42. In other words, the portion of the harness 3 that passes through the opening 40 is surrounded by the harness slider 42.
[0032] The harness slider 42 may have a connecting portion 47 and a locking portion 42C, as shown in Figures 5A, 5B, and 7B. The connecting portion 47 is a part of the harness slider 42 that protrudes in the displacement direction of the harness slider 42 and is connected to the protruding portion 23A. The locking portion 42C is a part that locks the connection between the fastener slider 43 and the harness slider 42.
[0033] More specifically, as shown in Figures 7A and 7B, the locking portion 42C is a pair of left and right parts configured at the connection point between the harness slider 42 and the fastener slider 43. The locking portion 42C locks the connection between the fastener slider 43 and the harness slider 42 by hooking onto the fastener slider 43. Furthermore, a snap-fit structure can be adopted for the locking portion 42C. That is, when connecting the fastener slider 43 and the harness slider 42, the pair of locking portions 42C are pushed apart to the left and right, and then return to their original position so as to hook onto the fastener slider 43, allowing for easy connection to the fastener slider 43. The connection can also be released by pushing the pair of locking portions 42C apart to the left and right. With this configuration, the locking portion 42C maintains its connection state so that the connection with the fastener slider 43 is not released when no external force is applied. In other words, the connection is locked.
[0034] The fastener slider 43 is a component that opens and closes the fastener 41. The two fastener sliders 43 are positioned opposite each other along the fastener 41, sandwiching the harness slider 42 along the front-to-rear direction of the automobile. In other words, the two fastener sliders 43 are configured to open the fastener 41 in the area sandwiched between the two fastener sliders 43, and to close the fastener 41 in the area of the opening 40 where the harness slider 42 is not present.
[0035] As shown in Figure 5B, the connecting portion 47 has a mounting portion 47A, a first support portion 47B, and a second support portion 47C. The mounting portion 47A is the portion on which the protruding portion 23A is mounted. The first support portion 47B is the portion that supports the side of the protruding portion 23A from the rear side of the automobile. The second support portion 47C is the portion that supports the side of the protruding portion 23A from the opposite side of the first support portion 47B, i.e., from the front side of the automobile.
[0036] As shown in Figure 4A below, the portion of harness 3 that is on the electrical equipment side of harness slider 42 is referred to as the first harness 3A. The portion of harness 3 that is on the automobile side of harness slider 42 is referred to as the second harness 3B.
[0037] The harness case 6 is a component that forms a storage space 6A for storing the excess length of the harness 3. As shown in Figures 2 and 6, the harness case 6 of this embodiment is located between the two slide rails 24 and in the space formed between the automobile body 50 and the floor material 51. In other words, the storage space 6A is located below the floor material 51.
[0038] The harness case 6 has the aforementioned opening 40 formed in a part of its upper surface, and the rest of its upper surface is covered by the flooring material 51. In other words, in this embodiment, the holding part 4 is provided on the upper surface of the harness case 6. The second harness 3B of the harness 3 is stored in a curved state within the storage space 6A. At least a portion of the upper slider 42A and the lower slider 42B are arranged within the storage space 6A.
[0039] As shown in Figure 6, a fastener housing section 46 may be formed at the lower part of the holding section 4, in which an open fastener 41 can be accommodated. In this embodiment, the fastener housing section 46 is formed by the holding section 4 and the harness case 6. The fastener housing section 46 is located above the storage space 6A in the vertical direction and at approximately the same height as the floor material 51 in the horizontal direction. The fastener 41, opened by the fastener slider 43, bends downward and is housed in the fastener housing section 46.
[0040] As shown in Figure 3, the movable part 2 slides along the slide rail 24. Since one end of the harness 3 is connected to the electrical equipment provided on the movable part 2, the harness 3 displaces along the opening 40 to follow the sliding of the movable part 2. Also, since the harness slider 42 is connected to the movable part 2 by the protruding part 23A, it displaces to follow the sliding of the movable part 2.
[0041] When harness 3 is displaced (for example, from A to B in Figure 3), at least a portion of the second harness 3B housed in harness case 6 is released outside harness case 6. This adjusts the length of the first harness 3A to follow the movable part 2. At this time, the curved portion of the second harness 3B housed in harness case 6 moves in the direction of the displacement of harness 3 (from X to Y as shown in Figure 2).
[0042] When the harness 3 and harness slider 42 reach the rear end of the holding part 4, the first support part 47B comes into contact with the end cap 45, as shown in Figure 5B. At this point, the displacement of the harness 3 and harness slider 42 stops. If the movable part 2 is to be slid further, the first support part 47B is pressed downward by the end cap 45, as shown in Figure 5B, and enters the space formed below the end cap 45.
[0043] As the first support portion 47B enters the space formed below the end cap 45, the first support portion 47B no longer supports the side of the protrusion 23A. In other words, the connection between the connecting portion 47 and the protrusion 23A is released. As a result, when attempting to slide the movable portion 2 further, the protrusion 23A moves away from the mounting portion 47A and displaces beyond the end cap 45.
[0044] When only the movable part 2 slides (for example, displaced from C to D in Figure 3), the length of the second harness 3B does not change. Harness 3 follows the movement of the movable part 2 due to the deformation of the first harness 3A.
[0045] When the movable part 2, with the connection between the connecting part 47 and the protruding part 23A released, slides forward of the automobile (for example, from D to B in Figure 3) and reaches the rear end of the holding part 4, the protruding part 23A reconnects with the connecting part 47. Specifically, the protruding part 23A displaces beyond the end cap 45 and reaches the upper part of the mounting part 47A.
[0046] Furthermore, when attempting to slide the movable part 2 forward of the vehicle, the protruding part 23A presses the second support part 47C forward of the vehicle. As the harness slider 42 is displaced forward of the vehicle, the first support part 47B is released from the space formed below the end cap 45. As a result, the first support part 47B ends up supporting the side of the protruding part 23A. In other words, the connecting part 47 and the protruding part 23A are reconnected.
[0047] When the movable part 2 is slid forward of the vehicle while the protruding part 23A is reconnected to the connecting part 47, at least a portion of the first harness 3A is housed inside the harness case 6. This adjusts the length of the first harness 3A to follow the movable part 2. At this time, the curved portion of the second harness 3B housed inside the harness case 6 moves in the direction from Y to X as shown in Figure 2.
[0048] [1-2. Effects] The first embodiment described in detail above provides the following effects. (1a) The movable part 2 slides relative to the vehicle together with the seat body 20. The harness 3 is directly or indirectly connected to the electrical equipment provided on the movable part 2, with one end fixed to the movable part 2 and the other end fixed to the vehicle. The holding part 4 is provided with an opening 40 that extends along the longitudinal direction of the seat and holds the fastener 41. The fastener 41 extends along the longitudinal direction of the seat and opens and closes the opening 40. The harness 3 passes through the opening 40 and is displaced along the longitudinal direction of the seat.
[0049] With this configuration, the harness 3 is displaced along the longitudinal direction of the sheet, so the excess portion of the harness 3 can be stored on the side opposite the sheet body 20 across the opening 40. In this configuration, the fastener 41 closes at least a part of the opening 40 provided in the holding part 4, that is, the opening 40 between the sheet body 20 and the area where the excess portion of the harness 3 is stored. Therefore, the entry of foreign matter into the area where the excess portion of the harness 3 is stored can be suppressed.
[0050] (1b) The above embodiment further includes a harness slider 42 positioned in the opening 40 and displaced together with the harness 3. The harness slider 42 is cylindrical with both ends positioned on either side of the holding portion 4. The harness 3 passes through the opening 40 by passing through the inside of the harness slider 42.
[0051] With this configuration, the harness 3 contacts the holding part 4 via the harness slider 42, so the opening 40 can be displaced without direct contact with the holding part 4. Therefore, the load on the harness 3 during its displacement can be suppressed, and the lifespan of the harness 3 can be extended. Here, the load on the harness 3 refers to, for example, the wear of the harness 3 caused by the displacement of the harness 3, which is in direct contact with the holding part 4, along the opening 40.
[0052] (1c) The above embodiment further comprises two fastener sliders 43 attached to the fastener 41 for opening and closing the fastener 41. The two fastener sliders 43 are mounted facing each other along the longitudinal direction of the sheet, sandwiching the harness slider 42. The harness slider 42 may be connected to the two fastener sliders 43.
[0053] With this configuration, the two fastener sliders 43 open the fasteners 41 in the area where the harness 3 and harness sliders 42 are located, while simultaneously displacing the opening 40 provided in the holding portion 4 together with the harness 3 and harness sliders 42. Therefore, it is possible to smoothly displace the harness 3 and harness sliders 42 while suppressing the entry of foreign matter into the area where the excess length of the harness 3 is stored.
[0054] (1d) In the above embodiment, the harness slider 42 further has a locking portion 42C configured to fix two fastener sliders 43. With this configuration, the harness slider 42 that covers the harness 3 and the fastener slider 43 that opens and closes the fastener 41 can be manufactured as separate components. Therefore, they can be easily assembled.
[0055] Furthermore, this configuration prevents the two fastener sliders 43 from moving away from the harness slider 42. Therefore, it is possible to prevent the fasteners 41 in areas where the harness 3 and harness slider 42 are not located from opening, and to prevent foreign objects from entering the area where the excess length of the harness 3 is stored.
[0056] (1e) The above embodiment further comprises a fastener housing 46 configured to house the fastener 41. The fastener 41 is configured to be housed in the fastener housing 46 when the fastener 41 is opened.
[0057] With this configuration, interference between the fastener 41, which is open in the area where the harness 3 and harness slider 42 are positioned, and the harness 3 and harness slider 42 can be suppressed. Therefore, the harness 3 and harness slider 42 can be smoothly displaced along the opening 40 provided in the holding part 4.
[0058] (1f) In the above embodiment, the movable part 2 further has a protruding part 23A that protrudes toward the holding part 4. The harness slider 42 further has a connecting part 47 that is connected to the protruding part 23A. With this configuration, the harness slider 42 is connected to the protruding part 23A and therefore displaces integrally with the movable part 2. In other words, since the harness 3 is displaced by displacing the harness slider 42, the harness 3 can be displaced without applying excessive force to the harness 3. As a result, the load on the harness 3 during its displacement can be suppressed, and the lifespan of the harness 3 can be extended.
[0059] (1g) In the above embodiment, the holding portion 4 further has an end cap 45 at the end of the opening 40. The connecting portion 47 has a mounting portion 47A, a first support portion 47B and a second support portion 47C. The mounting portion 47A is configured on which the protrusion 23A is mounted. The first support portion 47B and the second support portion 47C are configured to support the protrusion 23A by sandwiching it from the sides. When the protrusion 23A moves along the longitudinal direction of the sheet and the harness slider 42 reaches the end, the first support portion 47B is pressed by the end cap 45 and displaced downward, so as to transition to a state where it does not support the sides of the protrusion 23A. When the protrusion 23A moves further along the longitudinal direction of the sheet, the protrusion 23A is configured to move away from the mounting portion 47A and beyond the end cap 45.
[0060] With this configuration, when the harness slider 42 reaches the end of the opening 40, the protruding portion 23A separates from the mounting portion 47A and is no longer supported by the first support portion 47B and the second support portion 47C. In other words, the protruding portion 23A is released from the connection portion 47 and moves to a position beyond the end cap 45. As a result, the movable portion 2 can be configured to slide over a longer distance than the range of displacement of the harness slider 42.
[0061] [2. Other Embodiments] Although embodiments of the present disclosure have been described above, the present disclosure is not limited to the embodiments described above and can be implemented in various modified forms.
[0062] (2a) In the above embodiment, the retaining portion 4 had an end cap 45, but it is not limited to this. For example, the harness case 6 may have an end cap 45.
[0063] (2b) In the above embodiment, the harness slider 42 was formed from an upper slider 42A and a lower slider 42B, but is not limited thereto. For example, the harness slider 42 may be formed as a single component. (2c) The fastener 41 may be configured such that a portion of the tape extending in the longitudinal direction of the two sheets overlaps to close the opening 40. In this case, the harness slider 42 described later is not required.
