Description

[Technical field]

[0001] The present disclosure relates to a vehicle seat having a function of folding a back frame forward (hereinafter also referred to as a release function or a fold-down function). [Background technology]

[0002] For example, in the vehicle seat described in Patent Document 1, when either one of two operating levers is operated, a release function is activated and the seat back folds down. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Patent No. 5895810 Summary of the Invention [Problem to be solved by the invention]

[0004] The present disclosure discloses an example of a vehicle seat that can achieve a release function with two operating levers and that can achieve this function with a simple configuration. [Means for solving the problem]

[0005] It is desirable for a vehicle seat to be installed in a vehicle to have at least one of the following configuration requirements, for example. That is, the constituent elements are a back frame (51) that constitutes the framework of the seat back (5), a cushion frame (31) that constitutes the framework of the seat cushion (3), a first recliner (61) and a second recliner (62) that connect the back frame (51) and the cushion frame (31) and that can adjust the angle of the back frame (51) relative to the cushion frame (31), a first operating lever (71) and a second operating lever (72) that are rotated by the user during a release operation to tilt the back frame (51) forward, and a release pin (8) that rotates mechanically in conjunction with the rotation of the first operating lever (71) during a release operation, and that rotates to release the first recliner (61). a release pin (8) that operates the seat backrest, a first release lever (91) that rotates integrally with the release pin (8), a first operating cable (11) connected to the first release lever (91) and that transmits the rotation of the release pin (8) to the second recliner (62) to release the second recliner (62), a second release lever (92) that is arranged on the same side as the first release lever (91) with respect to the first recliner (61) in the seat width direction and that rotates integrally with the release pin (8), and a second operating cable (12) connected to the second release lever (92) and that transmits the operation of the second operating lever (72) to the second release lever (92).

[0006] As a result, in this vehicle seat, when the first operating lever (71) is operated, the release pin (8) rotates to release the first recliner (61), and the first release lever (91) rotates to release the second recliner (62) via the first operating cable (11). Therefore, the first recliner (61) and the second recliner (62) are released by operating the first operating lever (71), thereby achieving a release operation.

[0007] In addition, when the second operating lever (72) is operated, the operation of the second operating lever (72) is transmitted to the second release lever (92) via the second operating cable (12), causing the release pin (8) to rotate and release the first recliner (61).

[0008] At this time, the first release lever (91) rotates in conjunction with the rotation of the release pin (8), and the second recliner (62) is also released via the first operating cable (11). Therefore, the first recliner (61) and the second recliner (62) are released by operating the second operating lever (72), thereby achieving a release operation. As described above, the release function can be performed with a simple configuration.

[0009] In addition, since the first release lever (91) and the second release lever (92) are disposed on the same side of the first recliner (61), the configuration on the opposite side of the first recliner (61) from the first release lever (91) can be simplified, which in turn makes it possible to easily provide a new mechanism on the opposite side.

[0010] The vehicle seat may have the following configuration, for example. That is, it is desirable that the first release lever (91) is disposed on the opposite side of the release pin (8) from the second release lever (92). This can prevent the first release lever (91) or the second release lever (92) from becoming too long in the vehicle seat.

[0011] In other words, if the first release lever (91) is positioned on the same side of the release pin (8) as the second release lever (92) and the first dimension and the second dimension are the same, the first operating cable (11) and the second operating cable (12) will interfere with each other.

[0012] The first dimension refers to the dimension from the release pin (8) to the connection between the first operating cable (11) and the first release lever (91). The second dimension refers to the dimension from the release pin (8) to the connection between the second operating cable (12) and the second release lever (92).

[0013] Therefore, in a configuration in which the first release lever (91) is positioned on the same side as the second release lever (92) with respect to the release pin (8), the first dimension and the second dimension will have to be different, and the first release lever (91) or the second release lever (92) will become longer.

[0014] In contrast, in the vehicle seat, the first release lever (91) is positioned on the opposite side of the release pin (8) from the second release lever (92), so that there is no interference between the first operating cable (11) and the second operating cable (12).

[0015] Therefore, in the vehicle seat, the first dimension and the second dimension can be made the same, so that the first release lever (91) or the second release lever (92) can be prevented from becoming too long.

[0016] It is desirable that the first release lever (91) and the second release lever (92) are disposed on the outer side in the seat width direction with respect to the first recliner (61). In this way, by disposing a cover such as a shield on the outer side, the first release lever (91) and the second release lever (92) can be hidden, thereby improving the design of the vehicle seat.

[0017] The vehicle seat also includes a regulating portion (14) that, when released, regulates the first operating cable (11) and the second operating cable (12) from being displaced in a direction intersecting the routing direction of the first operating cable (11) and the second operating cable (12).

[0018] It is desirable that the restricting portion (14) is configured to restrict the first operating cable (11) from being displaced in one direction while allowing it to be displaced in the other direction, and to restrict the second operating cable (12) from being displaced in the other direction while allowing it to be displaced in one direction, thereby making it possible to effectively restrict the displacement of the first operating cable (11) and the second operating cable (12).

[0019] Furthermore, it is preferable that the first release lever (91) and the second release lever (92) are an integral part, and that the first release lever (91) and the second release lever (92) are symmetrical in shape with respect to the release pin (8). As a result, the integral part can be attached to either the right or left side of the vehicle seat.

[0020] Incidentally, the symbols in the above parentheses are examples showing the corresponding relationship with the specific configurations etc. described in the embodiments described below, and the present disclosure is not limited to the specific configurations etc. shown by the symbols in the above parentheses.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0022] The following "embodiment of the invention" shows an example of an embodiment that falls within the technical scope of the present disclosure. In other words, the invention-specific matters described in the claims are not limited to the specific configurations and structures shown in the following embodiment.

[0023] This embodiment is an example in which a vehicle seat according to the present disclosure is applied to a seat (hereinafter, referred to as a vehicle seat) mounted on a vehicle such as a car. Arrows and diagonal lines indicating directions are provided in each figure to facilitate understanding of the relationships between the figures and the shapes of components or parts.

[0024] Therefore, the vehicle seat is not limited to the directions shown in the drawings. The directions shown in the drawings are directions in a state in which the vehicle seat according to the present embodiment is assembled to a vehicle. The drawings with diagonal lines do not necessarily show cross-sectional views.

[0025] At least one of each of the members or parts described with a reference number is provided, unless otherwise specified by "one". In other words, unless otherwise specified by "one", two or more of the member may be provided. The vehicle seat shown in the present disclosure includes at least one of the components such as the members or parts described with a reference number and the structural parts shown in the drawings.

[0026] (First embodiment) <1. Overview of vehicle seats> 1, the vehicle seat 1 includes at least a seat cushion 3 and a seat back 5. The seat cushion 3 is a portion for supporting the buttocks of a seated occupant. The seat back 5 is a portion for supporting the back of the seated occupant.

[0027] The seat cushion 3 is configured to include at least a cushion frame 31 and a cushion pad (not shown), etc. The cushion frame 31 forms the framework of the seat cushion 3. The cushion pad is an elastic member such as urethane foam.

[0028] The cushion frame 31 according to this embodiment is a frame-shaped frame including at least two cushion side frames 32, 33 and connecting members 34 to 36. The cushion side frame 32 is disposed on one end side in the seat width direction and extends in the front-rear direction of the seat.

[0029] The cushion side frame 33 is disposed on the other end side in the seat width direction and extends in the seat front-rear direction. The connecting members 34 to 36 extend in the seat width direction and connect the two cushion side frames 32, 33 together.

[0030] The seat back 5 is configured to include at least a back frame 51 and a cushion pad (not shown), etc. The back frame 51 forms the framework of the seat back 5. The cushion pad is an elastic member such as urethane foam.

[0031] The back frame 51 according to this embodiment is a frame-shaped frame including at least two back side frames 52, 53 and connecting members 54, 55. The back side frame 52 is disposed on one end side in the seat width direction and extends substantially in the vertical direction.

[0032] The back side frame 53 is disposed on the other end side in the seat width direction and extends substantially in the vertical direction. The connecting members 54, 55 extend in the seat width direction and connect the two back side frames 52, 53 to each other.

[0033] 3, the cushion frame 31 and the back frame 51 are connected via a first recliner 61 and a second recliner 62. Specifically, the first recliner 61 connects the cushion side frame 32 and the back side frame 52.

[0034] The second recliner 62 connects the cushion side frame 33 and the back side frame 53. The first recliner 61 and the second recliner 62 are mechanisms for adjusting the angle of the back frame 51 relative to the cushion frame 31.

[0035] The first recliner 61 and the second recliner 62 are configured to include a ratchet with an internal gear, and a pawl with external teeth that engages with the internal gear. This configuration is similar to that of the recliner disclosed in, for example, JP 2000-102440 A.

[0036] In addition, the rear end sides of the cushion side frames 32, 33 are curved in a substantially arc shape as shown in Fig. 2. Therefore, the cushion side frames 32, 33 have a shape in which the rear end sides are raised.

[0037] <2. Configuration for release function> The release function (also called a fold-down function) is a function for folding down the back frame 51 forward so that the seat back 5 approaches the seat cushion 3. As components for realizing the release function, the present embodiment includes at least the following components.

[0038] That is, as shown in Figures 1 to 3, the vehicle seat 1 is equipped with a first operating lever 71, a second operating lever 72, a release pin 8, a first release lever 91, a second release lever 92, a first operating cable 11, and a second operating cable 12, etc.

[0039] <2.1 Control lever> The first operating lever 71 and the second operating lever 72 are operating parts that are rotated by the user when activating the release function. The first operating lever 71 is provided in a position close to the first recliner 61 as shown in Fig. 1. The second operating lever 72 is provided on the back side of the seat back 5.

[0040] <2.2 Release pin> The release pin 8 is a shaft member that rotates mechanically in conjunction with the rotation of the first operating lever 71 when the release function is activated (hereinafter, referred to as the release operation). When the release pin 8 rotates, the first recliner 61 operates to tilt the back frame 51 forward (hereinafter, also referred to as the release operation).

[0041] Specifically, when the release pin 8 rotates, the engagement between the ratchet and the pawl of the first recliner 61 is released. As a result, the back frame 51 is caused to fall forward by the elastic force of the spiral spring (not shown).

[0042] 3, in this embodiment, the first operating lever 71 is directly connected to the release pin 8. Therefore, when a user rotates the first operating lever 71, the release pin 8 rotates in conjunction with the first operating lever 71.

[0043] <2.3 First release lever, second release lever and operating cable> 2, the first release lever 91 and the second release lever 92 are levers that rotate integrally with the release pin 8. That is, in this embodiment, the first release lever 91 and the second release lever 92 are an integral part, and the integral part is connected to the release pin 8.

[0044] As shown in FIG. 4, the first release lever 91 is positioned on the opposite side of the second release lever 92 across the release pin 8, and the integrated first release lever 91 and second release lever 92 are configured in a symmetrical shape with respect to the release pin 8.

[0045] Furthermore, the second release lever 92 is disposed on the same side as the first release lever 91 with respect to the first recliner 61 in the seat width direction. Specifically, the first release lever 91 and the second release lever 92 are disposed on the outer side with respect to the first recliner 61 in the seat width direction.

[0046] The outer side in the seat width direction with respect to the first recliner 61 refers to the side opposite the second recliner 62 across the first recliner 61 in the seat width direction. For this reason, the first release lever 91 and the second release lever 92 according to this embodiment are disposed on the left side of the first recliner 61 as shown in FIG.

[0047] 4, the first operating cable 11 is a control cable connected to the first release lever 91. The first operating cable 11 transmits the rotation of the release pin 8 to the second recliner 62 to release the second recliner 62.

[0048] Specifically, as shown in Fig. 3, the first operating cable 11 connects the first operating lever 71 and the second recliner 62 via a cable joint 13. Therefore, when the release pin 8 rotates and the first recliner 61 performs a release operation, the second recliner 62 performs a release operation in conjunction with the release operation of the first recliner 61.

[0049] 4, the second operation cable 12 is a control cable connected to the second release lever 92. The second operation cable 12 transmits the operation of the second operation lever 72 to the second release lever 92.

[0050] The first operating cable 11 and the second operating cable 12 are pull-type control cables capable of transmitting only a pulling force. The inner cable 12A of the second operating cable 12 is engaged with the second release lever 92 only when the second operating lever 72 is operated.

[0051] In other words, when the first operating lever 71 is rotated and the release pin 8 and the first release lever 91 rotate in the direction indicated by the arrow in Figure 4 (hereinafter referred to as the release direction), the inner cable 12A is not engaged with the second release lever 92.

[0052] Therefore, only the second release lever 92 rotates in the release direction. That is, when the first operating lever 71 is rotated, the first release lever 91 and the second release lever 92 rotate in the release direction.

[0053] At this time, tension acts on the inner cable 11A of the first operating cable 11, so that the operating force is transmitted to the second recliner 62 via the first operating cable 11. At this time, the inner cable 12A is not engaged with the second release lever 92, so only the second release lever 92 rotates in the release direction, and the operating force of the first operating lever 71 is not transmitted to the second operating lever 72.

[0054] 5, the cushion side frame 32 on which the first release lever 91 and the second release lever 92 are arranged is provided with a restricting portion 14. The restricting portion 14 restricts the first operating cable 11 and the second operating cable 12 from being displaced in a direction intersecting the wiring direction of the cables 11, 12 (in the vertical direction in this embodiment) during a release operation.

[0055] Specifically, as shown in FIG. 6, the regulating portion 14 regulates the first operating cable 11 from being displaced in one direction (upward in this embodiment) while allowing it to be displaced in the other direction (downward in this embodiment).

[0056] Furthermore, the restricting portion 14 restricts the second operation cable 12 from being displaced in the other direction (downward in this embodiment) and allows it to be displaced in one direction (upward in this embodiment).

[0057] That is, the restricting portion 14 has at least a partition portion 14A. The partition portion 14A is a member that is substantially perpendicular to a direction that intersects with the wiring direction (in this embodiment, the up-down direction). The first operation cable 11 is routed on the other side (in this embodiment, the lower side) of the partition portion 14A. The second operation cable 12 is routed on the one side (in this embodiment, the upper side) of the partition portion 14A.

[0058] As shown in FIG. 5, the position of partition portion 14A is shifted forward and downward with respect to at least the positions of the connection portion between first operating cable 11 and first release lever 91 and the connection portion between second operating cable 12 and second release lever 92.

[0059] <2.4 Operation of the first release lever and the second release lever, etc.> When the seat back 5 is not reclined, that is, before the release operation, if the first operating lever 71 is operated in the direction of the arrow shown in FIG. 1, the release pin 8 rotates in the release direction, and the first release lever 91 also rotates in the release direction, as shown in FIG. 4.

[0060] As a result, the first recliner 61 is released, and the first operating cable 11 is operated so as to be pulled by the first release lever 91, so that the second recliner 62 is also released.

[0061] Therefore, the seat back 5 is tilted down as shown in Fig. 7. At this time, since the inner cable 12A is not locked by the second release lever 92, only the second release lever 92 rotates in the release direction.

[0062] When the second operating lever 72 is operated while the seat back 5 is not reclined, that is, before the release operation, the inner cable 12A is pulled, and the second release lever 92 rotates in the release direction.

[0063] As a result, the release pin 8 and the first release lever 91 also rotate in the release direction, causing the first recliner 61 to be released, and the first operating cable 11 is operated so as to be pulled by the first release lever 91, causing the second recliner 62 to also be released.

[0064] <3. Features of the Vehicle Seat According to the Present Embodiment (Especially, the Configuration Related to the Release Function)> In the vehicle seat 1 according to this embodiment, when the first operating lever 71 is operated, the release pin 8 rotates to release the first recliner 61, and the first release lever 91 rotates to release the second recliner 62 via the first operating cable 11. Therefore, the first recliner 61 and the second recliner 62 are released by operating the first operating lever 71, thereby achieving a release operation.

[0065] In addition, when the second operating lever 72 is operated, the operation of the second operating lever 72 is transmitted to the second release lever 92 via the second operating cable 12, causing the release pin 8 to rotate and release the first recliner 61.

[0066] At this time, the first release lever 91 rotates in conjunction with the rotation of the release pin 8, so that the second recliner 62 is also released via the first operating cable 11. Therefore, the first recliner 61 and the second recliner 62 are released by operating the second operating lever 72, thereby achieving a release operation. As described above, the release function can be performed with a simple configuration.

[0067] In addition, because the first release lever 91 and the second release lever 92 are disposed on the same side of the first recliner 61, the configuration on the opposite side of the first release lever 91 across the first recliner 61 can be simplified. This in turn makes it possible to easily provide a new mechanism on that opposite side.

[0068] The first release lever 91 is disposed on the opposite side to the second release lever 92 across the release pin 8. This makes it possible to prevent the first release lever 91 or the second release lever 92 from becoming too long in the vehicle seat 1.

[0069] In other words, when the first release lever 91 is positioned on the same side as the second release lever 92 with respect to the release pin 8 and the first dimension L1 (see Figure 5) and the second dimension L2 (see Figure 5) are the same, the first operating cable 11 and the second operating cable 12 will interfere with each other.

[0070] The first dimension L1 refers to the dimension from the release pin 8 to the connection between the first operating cable 11 and the first release lever 91. The second dimension L2 refers to the dimension from the release pin 8 to the connection between the second operating cable 12 and the second release lever 92.

[0071] Therefore, in a configuration in which the first release lever 91 is positioned on the same side as the second release lever 92 with respect to the release pin 8, the first dimension L1 and the second dimension L2 must be different dimensions, and the first release lever 91 or the second release lever 92 becomes longer.

[0072] In contrast, in the vehicle seat 1, the first release lever 91 is positioned on the opposite side of the release pin 8 from the second release lever 92, so that there is no interference between the first operating cable 11 and the second operating cable 12.

[0073] Therefore, in the vehicle seat 1, the first dimension L1 and the second dimension L2 can be made the same, so that the first release lever 91 or the second release lever 92 can be prevented from becoming too long.

[0074] The first release lever 91 and the second release lever 92 are disposed on the outer side in the seat width direction relative to the first recliner 61. This allows the first release lever 91 and the second release lever 92 to be hidden by disposing a cover 15 (see FIG. 8) such as a shield on the outer side, thereby improving the design of the vehicle seat 1.

[0075] The regulating portion 14 is configured to regulate the first operating cable 11 against upward displacement while allowing it to be displaced downward, and to regulate the second operating cable 12 against downward displacement while allowing it to be displaced upward.

[0076] This makes it possible to effectively restrict the displacement of the first operation cable 11 and the second operation cable 12. That is, for example, when an operation force, i.e., tension, acts on the first operation cable 11, the first operation cable 11 that is routed in a curved state tends to become straight.

[0077] For this reason, in this embodiment, when an operating force acts on the first operating cable 11, the first operating cable 11 tries to be displaced upward. Therefore, it is necessary and sufficient for the restricting portion 14 to restrict the upward displacement of the first operating cable 11.

[0078] Furthermore, the first release lever 91 and the second release lever 92 are an integral part, and the first release lever 91 and the second release lever 92 are symmetrical with respect to the release pin 8. Therefore, the integral part can be attached to either the right or left side of the vehicle seat 1.

[0079] (Other embodiments) In the above-described embodiment, the second release lever 92 is disposed on the same side as the first release lever 91 with respect to the first recliner 61 in the seat width direction. However, the present disclosure is not limited to this. That is, the present disclosure may be configured such that, for example, the second release lever 92 is disposed on the opposite side to the first release lever 91.

[0080] In the above-described embodiment, the first release lever 91 is positioned on the opposite side of the second release lever 92 across the release pin 8, and the first release lever 91 and the second release lever 92 are configured to be symmetrical with respect to the release pin 8.

[0081] However, the present disclosure is not limited to this. That is, the present disclosure may be configured, for example, such that the first release lever 91 is disposed on the same side as the second release lever 92 with the release pin 8 in between, or such that the first release lever 91 and the second release lever 92 are configured to be asymmetrical with respect to the release pin 8.

[0082] In the above-described embodiment, the first release lever 91 and the second release lever 92 are disposed on the outside. However, the present disclosure is not limited to this. That is, the present disclosure may be configured such that, for example, the first release lever 91 and the second release lever 92 are disposed on the inside.

[0083] In the above-described embodiment, the first release lever 91 and the second release lever 92 are an integral part. However, the present disclosure is not limited to this. That is, in the present disclosure, for example, the first release lever 91 and the second release lever 92 may be separate parts.

[0084] In the above-described embodiment, the restricting portion 14 is provided to restrict the displacement of the two operation cables 11 and 12. However, the present disclosure is not limited to this. That is, the present disclosure may be configured such that the restricting portion 14 is eliminated, for example.

[0085] In the above-described embodiment, the first operating lever 71 is disposed coaxially with the release pin 8, and the second operating lever 72 is provided on the back surface of the seat back 5. However, the present disclosure is not limited to this.

[0086] That is, the disclosure may be configured, for example, such that the first operating lever 71 is provided on the side of the seat cushion 3, and the second operating lever 72 is provided on the shoulder of the seat back 5. In this configuration, it is preferable that the operating force of the first operating lever 71 is transmitted to the release pin 8 via a link mechanism or an operating cable.

[0087] In the above embodiment, the vehicle seat according to the present disclosure is applied to a vehicle. However, the application of the invention disclosed in this specification is not limited thereto. That is, the disclosure can be applied to, for example, seats used in vehicles such as railroad cars, ships, and aircraft, as well as stationary seats used in theaters, homes, and the like.

[0088] Furthermore, the present disclosure is not limited to the above-mentioned embodiments as long as it is consistent with the gist of the disclosure described in the above-mentioned embodiments. Therefore, the present disclosure may be a configuration in which at least two of the above-mentioned embodiments are combined, or a configuration in which any of the components illustrated or the components described with reference numerals in the above-mentioned embodiments are eliminated.
