Description

Technical Field

[0001] This disclosure relates to car seats installed in automobiles. Background Technology

[0002] In the prior art, there are known techniques that can prevent foreign objects from intruding into the sliding guide rails of the sliding support mechanism of an automotive seat.

[0003] For example, Japanese Patent Application Publication No. 2007-69809 proposes a technical solution: installing a closure member in a manner that clamps the opening of the sliding guide rail, thereby preventing foreign objects from entering the interior of the sliding guide rail by closing the closure member except for the area where the sliding bracket is located. Summary of the Invention

[0004] However, the wiring harness connected to the car seat needs to have its length adjusted to accommodate the movement of the car seat. Therefore, the car seat has an area (e.g., a wiring harness box) to accommodate any excess wiring harness length, and it is necessary to prevent foreign objects from entering this area.

[0005] One aspect of this disclosure is aimed at preventing foreign objects from intruding into the storage area of ​​the excess wiring harness of an automotive seat installed in a vehicle.

[0006] One aspect of this disclosure provides an automotive seat mounted in a vehicle. The automotive seat includes a movable part, a wiring harness, a closure, and a retaining part. The movable part includes a seat body having at least a seat cushion and is used to slide relative to the vehicle together with the seat body. The wiring harness is directly or indirectly connected to electrical equipment disposed on the movable part and has a first end fixed to the movable part and a second end fixed to the vehicle. The closure extends along the longitudinal direction of the seat. The retaining part is fixed to the vehicle and is used to retain the closure. An opening extending along the longitudinal direction of the seat is provided in the retaining part. The closure is used to open or close the opening. The wiring harness is configured to pass through the opening and be displaced along the longitudinal direction of the seat.

[0007] According to the above configuration, since the wiring harness is displaced along the longitudinal direction of the seat, the excess length of the wiring harness can be stored on the opposite side of the seat body through the opening. In this configuration, the closure member closes at least a portion of the opening provided in the retaining part, that is, the opening located between the seat body and the area where the excess length of the wiring harness is stored. Therefore, the automotive seat can prevent foreign objects from entering the storage area for the excess length of the wiring harness.

[0008] In one embodiment of this disclosure, the automotive seat may further include a wiring harness slider disposed at an opening and moving together with the wiring harness. The wiring harness slider is cylindrical, with its two ends located on either side of a retaining portion. The wiring harness may be configured to pass through the opening by passing through the interior of the wiring harness slider.

[0009] With the above configuration, the wiring harness contacts the retaining part via a wiring harness slider, thus allowing it to move within the opening without direct contact with the retaining part. Therefore, automotive seats can suppress the load on the wiring harness during its movement, thereby extending its service life.

[0010] In one embodiment of this disclosure, the automotive seat may further include two closure sliders mounted on a closure and used to open or close the closure. The two closure sliders may be positioned opposite each other along the longitudinal direction of the seat, separated by a wiring harness slider. The wiring harness slider may be connected to the two closure sliders.

[0011] Based on the above configuration, the two closing member sliders can both open the closing members within the range where the wire harness slider is configured, and can also move together with the wire harness slider in the opening provided on the retaining part. Therefore, the automotive seat can smoothly realize the movement of the wire harness and the wire harness slider, and can also prevent foreign objects from entering the storage area of ​​the excess wire harness length.

[0012] In one embodiment of this disclosure, the wire harness slider may also have a locking part for securing the two closing member sliders to the wire harness slider.

[0013] Based on the above configuration, the wire harness slider covering the wire harness and the closure slider for opening / closing the closure can be manufactured as separate components. Therefore, simple assembly can be achieved.

[0014] Furthermore, based on the above configuration, it is also possible to prevent the two closing member sliders from detaching from the wiring harness slider and moving. Therefore, the automotive seat can both prevent the closing members from opening in the area where the wiring harness and wiring harness slider are not located, and prevent foreign objects from entering the storage area of ​​the excess length of the wiring harness.

[0015] In one embodiment of this disclosure, the car seat may further have a closure receiving portion configured to receive a closure. The closure may be configured such that, when the closure is opened, it is received within the closure receiving portion.

[0016] Based on the above configuration, interference between the opened closure and the wire harness and the wire harness slider within the area where the wire harness and the slider are configured can be suppressed. Therefore, the wire harness and the wire harness slider can smoothly move along the opening provided in the retaining part.

[0017] In one embodiment of this disclosure, the movable part may further have a protrusion that protrudes toward the retaining part. The wire harness slider may further have a connecting part that connects to the protrusion.

[0018] Based on the above configuration, since the wire harness slider is connected to the protrusion, the wire harness slider and the movable part can move together. In other words, the automotive seat is configured such that the wire harness is moved by displacing the wire harness slider, thus eliminating the need to apply unnecessary external force to the wire harness. Therefore, the automotive seat can suppress the load on the wire harness during displacement, thereby extending the service life of the wire harness.

[0019] In one embodiment of this disclosure, the retaining portion may also have an end cap at the end of the opening. The connecting portion may have a mounting portion, a first support portion, and a second support portion. The mounting portion is configured to mount the protrusion. The first support portion and the second support portion are configured to support the protrusion by clamping it from the side. When the protrusion moves along the longitudinal direction of the seat and the wiring harness slider has reached the end, the first support portion may be configured to be pressed down by the end cap and displaced downward, thereby changing to a state where it does not support the side of the protrusion. When the protrusion continues to move along the longitudinal direction of the seat, the protrusion may be configured to detach from the mounting portion and move past the end cap.

[0020] According to the above configuration, when the wire harness slider reaches the end of the opening, the protrusion is in a state of being detached from the mounting portion and not supported by the first support portion and the second support portion. That is, the connection between the protrusion and the connecting portion is released, and it moves to a position beyond the end cover. Therefore, the movable portion can adopt a structure that exceeds the displacement range of the wire harness slider and achieves a longer sliding distance. Attached Figure Description

[0028] The embodiments of this disclosure will now be described with reference to the accompanying drawings.

[0029] The embodiments described below are examples illustrating embodiments within the scope of this disclosure. That is, the technical solutions described in the claims are not limited to the specific structures or configurations shown in the following embodiments.

[0030] [1. Implementation Method]

[0031] [1-1. Composition]

[0032] Figure 1 The car seat 1 shown is a seat mounted on a car and has the function of sliding relative to the car. The car seat 1 includes a movable part 2, a wiring harness 3, a retaining part 4, and a closing member 41 (see, for example, reference...). Figure 2 (etc.). The automotive seat 1 may also include a wiring harness box 6, a sliding rail 24, and a wiring harness slider 42 (see, for example, reference). Figure 2 etc.), and closing slider 43 (refer to Figure 4B At least one of (etc.).

[0033] The movable part 2 is a portion that slides relative to the vehicle together with the seat body 20. In this embodiment, the movable part 2 moves along the longitudinal direction of the vehicle. The movable part 2 includes the seat body 20 and the seat cushion frame 23.

[0034] The seat body 20 is the part that supports the occupant when they are seated. The seat body 20 includes a seat cushion 21 and a seat back 22. The seat cushion 21 supports the lower body of the occupant. The seat back 22 supports the upper body of the occupant.

[0035] The seat cushion frame 23 is disposed at the lower part of the seat body 20 and is a component that supports the seat body 20. The seat cushion frame 23 is at least partially disposed within a sliding guide rail 24 and is configured to slide along the sliding guide rail 24. The sliding guide rail 24 is the portion where the seat cushion frame 23 is disposed and is fixed to the vehicle (e.g., automobile). Figure 6 The vehicle body 50 shown is part of the vehicle interior floor component 51.

[0036] For example, the seat frame 23 can be configured to slide within the sliding guide rail 24 by rollers provided at the lower part of the seat frame 23. Therefore, the movable part 2 is configured to slide relative to the car.

[0037] In this embodiment, the car seat 1 includes two seat cushion frames 23 and two sliding rails 24. The two seat cushion frames 23 support the seat body 20 at both ends in the seat width direction. The two sliding rails 24 are configured such that their longitudinal direction is parallel to each other along the longitudinal direction of the car.

[0038] The seat frame 23 may have a protrusion 23A. For example... Figure 5A As shown, the protrusion 23A is a part that protrudes toward the retaining part 4.

[0039] Wiring harness 3 is an electrical connection used to electrically connect electrical equipment installed on the movable part 2 to the vehicle. For example, wiring harness 3 may include power lines for connecting devices such as motors driving the power seat and seat heaters to a power source such as a vehicle battery, and signal lines for controlling the power seat. Both power lines and signal lines are insulated. Wiring harness 3 has a first end fixed to the movable part and a second end fixed to the vehicle. The second end of wiring harness 3 can be fixed to any part of the vehicle. For example, the second end of wiring harness 3 can be fixed to a part of the vehicle body 50. Alternatively, the second end of wiring harness 3 can be fixed to a sliding guide rail 24. Wiring harness 3 is flexible and can be easily deformed. Wiring harness 3 is protected by covering it with a flexible corrugated tube (not shown).

[0040] The retaining part 4 is a component used to retain the closure 41. The retaining part 4 is disposed adjacent to one of the two sliding guide rails 24 and parallel to the sliding guide rail 24. The retaining part 4 is positioned between the two sliding guide rails 24. The retaining part 4 is fixed to the vehicle. Figure 4A and Figure 6 As shown, an opening 40 extending along the longitudinal direction of the seat is formed in the retaining part 4. Here, the longitudinal direction of the seat refers to the direction in which the movable part 2 slides. That is, in this embodiment, the longitudinal direction of the seat refers to the front-to-back direction of the vehicle. The retaining part 4 has an end cap 45. Figure 5A and Figure 5B As shown, end cap 45 is formed at the end of opening 40.

[0041] The closure member 41 is a component used to open or close the opening 40. The closure member 41 extends along the longitudinal direction of the seat and is installed to cover at least a portion of the opening 40. In this embodiment, the closure member 41 is installed on the lower surface of the retaining part 4. The closure member 41 can be any type of fastener, such as a wire zipper, a surface zipper, etc.

[0042] like Figure 4A and Figure 4BThe wire harness slider 42 shown is a component that slides relative to and is displaced on the retaining part 4. In this embodiment, the wire harness slider 42 consists of an upper slider 42A and a lower slider 42B. The upper slider 42A is a component that covers the wire harness 3 from above. The lower slider 42B is a component that covers the wire harness 3 from below. Therefore, the wire harness slider 42 does not damage the wire harness 3 and can be easily assembled.

[0043] The wire harness slider 42 is configured such that its two vertical ends are located on both sides of the holding portion 4. The wire harness slider 42 is cylindrical and configured such that the wire harness 3 passes through the interior of the wire harness slider 42. That is, the portion of the wire harness 3 that passes through the opening 40 is surrounded by the wire harness slider 42.

[0044] like Figure 5A , Figure 5B and Figure 7B As shown, the wire harness slider 42 may have a connecting portion 47 and a locking portion 42C. The connecting portion 47 is a part of the wire harness slider 42 that protrudes in the displacement direction of the wire harness slider 42 and is connected to the protrusion 23A. The locking portion 42C is a part used to lock the connection between the closing member slider 43 and the wire harness slider 42.

[0045] More specifically, such as Figure 7A and Figure 7B As shown, the locking part 42C is a pair of left and right parts that form the connection point connecting the wire harness slider 42 and the closing member slider 43. The locking part 42C locks the connection between the closing member slider 43 and the wire harness slider 42 by hooking onto the closing member slider 43. Furthermore, the locking part 42C can adopt a snap-on structure. That is, when connecting the closing member slider 43 and the wire harness slider 42, the connection with the closing member slider 43 can be easily achieved by pushing the pair of locking parts 42C apart to the left and right, and then returning the locking parts 42C to their original position by hooking onto the closing member slider 43. Furthermore, the connection can be released by pushing the pair of locking parts 42C apart to the left and right. With the above configuration, the locking part 42C can maintain the connection with the closing member slider 43 without the application of external force, thus preventing the connection between the wire harness slider 42 and the closing member slider 43 from being released. In other words, the connection is locked.

[0046] The closing slider 43 is a component used to open or close the closing member 41. Two closing sliders 43 are configured to face each other across the wiring harness slider 42 along the longitudinal direction of the vehicle and to be arranged along the closing member 41. That is, the two closing sliders 43 are configured to open the closing member 41 within the area enclosed by the two closing sliders 43, and to close the closing member 41 within the area where the wiring harness slider 42 is not present at the opening 40.

[0047] like Figure 5B As shown, the connecting portion 47 includes a mounting portion 47A, a first support portion 47B, and a second support portion 47C. The mounting portion 47A is the portion that mounts the protrusion 23A. The first support portion 47B is the portion that supports the side of the protrusion 23A from the rear of the vehicle. The second support portion 47C is the portion that supports the side of the protrusion 23A from the opposite side of the first support portion 47B, that is, from the front of the vehicle.

[0048] In the following text, such as Figure 4A As shown, the portion of wire harness 3 located on the side closer to the electrical equipment than the wire harness slider 42 is referred to as the first wire harness 3A. The portion of wire harness 3 located on the side closer to the vehicle than the wire harness slider 42 is referred to as the second wire harness 3B.

[0049] The wire harness box 6 is a component that forms a storage space 6A, which is used to store the excess length of the wire harness 3. For example... Figure 2 and Figure 6 As shown, the wiring harness box 6 of this embodiment is disposed between two sliding guide rails 24 and in the space formed between the vehicle body 50 and the floor component 51. That is, the storage space 6A is located at the lower part of the floor component 51.

[0050] The opening 40 is formed on a portion of the upper surface of the wire harness box 6, and the remaining portion of the upper surface is covered by the floor member 51. That is, in this embodiment, the retaining part 4 is provided on the upper surface of the wire harness box 6. The second wire harness 3B in the wire harness 3 is stored in the storage space 6A in a bent state. At least a portion of the upper slider 42A and the lower slider 42B are disposed in the storage space 6A.

[0051] like Figure 6 As shown, a closure receiving portion 46 can be formed at the lower part of the holding portion 4, which can accommodate the opened closure portion 41. In this embodiment, the closure receiving portion 46 is formed by the holding portion 4 and the wire harness box 6. The closure receiving portion 46 is located above the storage space 6A in the vertical direction and at approximately the same height as the floor member 51 in the horizontal direction. The closure portion 41, which is opened by the closure slider 43, bends downward and is accommodated in the closure receiving portion 46.

[0052] like Figure 3 As shown, the movable part 2 slides along the sliding guide rail 24. Since the first end of the wire harness 3 is connected to the electrical equipment provided on the movable part 2, the wire harness 3 is displaced along the opening 40 in a manner that follows the sliding of the movable part 2. Furthermore, the wire harness slider 42 is connected to the movable part 2 via the protrusion 23A, so the wire harness slider 42 is displaced in accordance with the sliding of the movable part 2.

[0053] When harness 3 is displaced (for example, in Figure 3When the wire harness 3B is displaced from A to B, at least a portion of the second wire harness 3B housed in the wire harness box 6 is released from the wire harness box 6 to the outside. As a result, the length of the first wire harness 3A is adjusted in a manner that follows the movable part 2. At this time, the bent portion of the second wire harness 3B housed in the wire harness box 6 moves along the displacement direction of the wire harness 3 (i.e., Figure 2 (As shown, the movement is from X to Y).

[0054] When the wire harness 3 and the wire harness slider 42 reach the rear end of the holding part 4, as Figure 5B As shown, the first support portion 47B contacts the end cap 45. At this time, the displacement of the wire harness 3 and the wire harness slider 42 stops. If an attempt is made to continue sliding the movable portion 2, then as... Figure 5B As shown, the first support portion 47B is pressed downward by the end cap 45, thereby entering the space formed in the lower part of the end cap 45.

[0055] The first support portion 47B enters the space formed in the lower part of the end cover 45, and the first support portion 47B is in a state where it no longer supports the side of the protrusion 23A. That is, 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 will disengage from the mounting portion 47A and move past the end cover 45.

[0056] When only the movable part 2 slides (for example, in Figure 3 When the wire bundle 3 shifts from C to D, the length of the second wire bundle 3B remains unchanged. The wire bundle 3 follows the movable part 2 by deforming the first wire bundle 3A.

[0057] When the connection between the connecting part 47 and the protrusion 23A is released, the movable part 2 slides forward toward the front of the vehicle (for example, in...). Figure 3 When the protrusion 23A moves from D to B and reaches the rear end of the holding part 4, it reconnects with the connecting part 47. Specifically, the protrusion 23A moves past the end cover 45 and reaches the upper part of the mounting part 47A.

[0058] When attempting to slide the movable part 2 further forward towards the vehicle, the protrusion 23A presses the second support part 47C forward towards the vehicle. At this time, due to the displacement of the wiring harness slider 42 towards the vehicle, the first support part 47B is released from the space formed under the end cover 45. Thus, the first support part 47B is positioned to support the side of the protrusion 23A. In other words, the connecting part 47 is reconnected to the protrusion 23A.

[0059] When the movable part 2 is attempted to slide forward towards the vehicle with the protrusion 23A and the connecting part 47 reconnected, at least a portion of the first wire harness 3A is stored in the wire harness box 6. As a result, the length of the first wire harness 3A is adjusted to follow the movable part 2. At this time, the curved portion of the second wire harness 3B stored in the wire harness box 6 will follow... Figure 2 The movement is shown as moving from the Y to the X direction.

[0060] [1-2. Effects]

[0061] According to the first embodiment described in detail above, the following effects can be achieved.

[0062] (1a) The movable part 2 and the seat body 20 slide together relative to the vehicle. The wiring harness 3 is directly or indirectly connected to electrical equipment provided on the movable part 2, and has a first end fixed to the movable part 2 and a second end fixed to the vehicle. An opening 40 extending along the longitudinal direction of the seat is provided on the retaining part 4, and the retaining part 4 is used to retain the closing member 41. The closing member 41 extends along the longitudinal direction of the seat and is used to open or close the opening 40. The wiring harness 3 passes through the opening 40 and is displaced along the longitudinal direction of the seat.

[0063] According to the above configuration, since the wiring harness 3 is displaced along the longitudinal direction of the seat, the excess length of the wiring harness 3 can be stored on the opposite side of the seat body 20 through the opening 40. In this configuration, the closure member 41 closes at least a portion of the opening 40 provided in the retaining part 4, that is, the opening 40 located between the seat body 20 and the area where the excess length of the wiring harness 3 is stored. As a result, the automotive seat 1 can prevent foreign objects from entering the storage area of ​​the excess length of the wiring harness 3.

[0064] (1b) In the above embodiment, the automotive seat 1 further includes a wiring harness slider 42, which is disposed at the opening 40 and moves together with the wiring harness 3. The wiring harness slider 42 is cylindrical, with its two ends located on both sides of the holding portion 4. The wiring harness 3 passes through the opening 40 by passing through the interior of the wiring harness slider 42.

[0065] According to the above configuration, the wiring harness 3 contacts the retaining portion 4 via the wiring harness slider 42, thus allowing it to move within the opening 40 without direct contact with the retaining portion 4. Therefore, the automotive seat 1 can suppress the load on the wiring harness 3 during its movement, thereby extending its service life. Here, the load on the wiring harness 3 refers to, for example, the wear that occurs when the wiring harness 3, which is in direct contact with the retaining portion 4, moves along the opening 40.

[0066] (1c) In the above embodiment, the car seat 1 further includes two closing member sliders 43, which are mounted on the closing member 41 and are used to open or close the closing member 41. The two closing member sliders 43 are arranged to face each other across a wiring harness slider 42 along the longitudinal direction of the seat. The wiring harness slider 42 can be connected to the two closing member sliders 43.

[0067] Based on the above configuration, the two closing sliders 43 can both open the closing member 41 within the range where the wiring harness 3 and the wiring harness slider 42 are configured, and can also move together with the wiring harness 3 and the wiring harness slider 42 in the opening 40 provided on the holding part 41. Therefore, the automotive seat 1 can smoothly realize the movement of the wiring harness 3 and the wiring harness slider 42, and can also prevent foreign objects from entering the storage area of ​​the excess length of the wiring harness 3.

[0068] (1d) In the above embodiment, the wire harness slider 42 also has a locking part 42C, which is used to fix the two closing member sliders 43 to the wire harness slider 42.

[0069] Based on the above configuration, the wire harness slider 42 covering the wire harness 3 and the closing member slider 43 for opening / closing the closing member 41 can be manufactured as independent components. Therefore, simple assembly can be achieved.

[0070] Furthermore, based on the above configuration, it is also possible to prevent the two closing member sliders 43 from detaching from the wire harness slider 42 and moving. Therefore, the automotive seat 1 can both prevent the closing member 41 from opening in the area where the wire harness 3 and wire harness slider 42 are not located, and prevent foreign objects from entering the storage area of ​​the remaining length of the wire harness 3.

[0071] (1e) In the above embodiment, the car seat 1 also has a closure receiving portion 46, which is configured to receive a closure 41. The closure 41 is configured to be received in the closure receiving portion 46 when the closure 41 is opened.

[0072] According to the above configuration, interference between the closure 41, which has been opened within the area where the wire harness 3 and the wire harness slider 42 are disposed, and the wire harness 3 and the wire harness slider 42 can be suppressed. Therefore, the wire harness 3 and the wire harness slider 42 can be smoothly displaced along the opening 40 provided in the holding part 4.

[0073] (1f) In the above embodiment, the movable part 2 also has a protrusion 23A that protrudes toward the holding part 4. The wire harness slider 42 may also have a connecting part 47 that is connected to the protrusion 23A.

[0074] According to the above configuration, since the wire harness slider 42 is connected to the protrusion 23A, the wire harness slider 42 and the movable part 2 can move together. In other words, the automotive seat 1 is configured such that the wire harness 3 is moved by moving the wire harness slider 42, thus achieving the displacement of the wire harness 3 without applying unnecessary external force. Therefore, the automotive seat 1 can suppress the load on the wire harness 3 during its displacement, thereby extending the service life of the wire harness 3.

[0075] (1g) In the above embodiment, the retaining part 4 also has an end cap 45 at the end of the opening 40. The connecting part 47 has a mounting part 47A, a first support part 47B, and a second support part 47C. The mounting part 47A is configured to mount the protrusion 23A. The first support part 47B and the second support part 47C are configured to support the protrusion 23A in a manner that clamps the protrusion 23A from the side. When the protrusion 23A moves along the longitudinal direction of the seat and the wiring harness slider 42 has reached the end, the first support part 47B is configured to be pressed down by the end cap 45 and displaced downward, thereby changing to a state where it does not support the side of the protrusion 23A. When the protrusion 23A continues to move along the longitudinal direction of the seat, the protrusion 23A is configured to detach from the mounting part 47A and move past the end cap 45.

[0076] According to the above configuration, when the wire harness slider 42 reaches the end of the opening 40, the protrusion 23A is in a state of being detached from the mounting portion 47A and not supported by the first support portion 47B and the second support portion 47C. That is, the connection between the protrusion 23A and the connecting portion 47 is released, and it moves to a position beyond the end cover 45. Therefore, the movable portion 2 can adopt a structure that exceeds the displacement range of the wire harness slider 42 and achieves a longer sliding distance.

[0077] [2. Other Implementation Methods]

[0078] The embodiments of this disclosure have been described above, but this disclosure is not limited to the above embodiments and can be implemented in various modified ways.

[0079] (2a) In the above embodiment, the holding part 4 has an end cap 45, but it is not limited to this. For example, the wire harness box 6 may also have an end cap 45.

[0080] (2b) In the above embodiment, the wire harness slider 42 is composed of an upper slider 42A and a lower slider 42B, but it is not limited to this. For example, the wire harness slider 42 may also be formed as a single component.

[0081] (2c) Additionally, the closure 41 can be configured such that a portion of the two zipper straps extending along the longitudinal direction of the seat overlaps, and is configured to cover the opening 40. In this case, the harness slider 42 described later is unnecessary.
