Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, in the above prior art, the extended portion is relatively small and extends only slightly toward the door opening side and does not extend to the rear side of the seat cushion. However, there may be a case where a relatively large extended portion is provided to fill the space between the driver's seat and the passenger seat. In such a case, if a configuration is adopted in which the panel-shaped extended support portion extends from one seat side of the driver's seat and the passenger seat to the other seat side, the extended support portion becomes large, and there is room for improvement from the viewpoint of suppressing an increase in mass.

[0005] In consideration of the above facts, an object of the present invention is to obtain a vehicle seat capable of suppressing an increase in mass in a configuration in which an extended portion extending from a seat cushion is provided between a driver's seat and a passenger seat.

Means for Solving the Problems

[0006] The vehicle seat of the present invention as described in claim 1 is a vehicle seat comprising a seat of either a driver's seat or a passenger seat, and comprises a wire frame comprising: a cushion pan provided on the seat cushion of one of the driver's seat or the passenger seat and supporting a cushion pad portion from below the seat; an extended pad portion extending from the cushion pad portion toward the other seat of the driver's seat or the passenger seat; a first wire portion made of wire that supports the extended pad portion from below the seat and is fixed to the middle of the seat in the front-rear direction of the portion of the cushion pan toward the other seat, and extending in multiple ways toward the other seat to form a protruding portion; and a second wire portion fixed to the first wire portion and extending from the first wire portion toward the front and rear of the seat to form portions that support the front and rear of the extended pad portion. The first wire portion is fixed to the cushion pan via a bracket. Claim 2 The vehicle seat of the present invention described herein is a vehicle seat comprising one of a driver's seat and a passenger seat, and comprises a wire frame comprising: a cushion pan provided on the seat cushion of one of the driver's seat and the passenger seat and supporting a cushion pad portion from the lower side of the seat; an extended pad portion extending from the cushion pad portion toward the other seat of the driver's seat and the passenger seat; a first wire portion made of wire that supports the extended pad portion from the lower side of the seat, is fixed to the middle of the seat in the front-rear direction of the portion of the cushion pan toward the other seat, and extends in multiple ways toward the other seat to form a protruding portion; and a second wire portion fixed to the first wire portion and extending from the first wire portion toward the front and rear of the seat to form portions that support the front and rear of the extended pad portion. The pad, which includes the cushion pad portion and the extended pad portion, has a convex portion that enters from above the sheet into the space between the hanging portion on the front end side of the cushion pan and the portion forming the front end side of the wire frame, and fills the space.

[0007] The following are described in Claim 1 and Claim 2, respectivelyAccording to the configuration, the vehicle seat of the present invention is composed of one of the driver's seat and one of the passenger seat. In the seat cushion of one of the driver's seat and one of the passenger seat, the cushion pad portion is supported from below the seat by a cushion pan. An extension pad portion extends from the cushion pad portion toward the other seat of the driver's seat and one of the passenger seat, and this extension pad portion is supported from below the seat by a wire frame made of wire. Therefore, for example, compared to a proportional arrangement where the extension pad portion is supported from below the seat by a panel-shaped pan, it is possible to suppress the increase in mass.

[0008] Here, the wire frame is composed of a first wire section and a second wire section. The first wire section is fixed to the middle of the cushion pan in the seat-front-rear direction of the other seat-side portion and extends in multiple directions toward the other seat-side to form an overhanging portion. The second wire section is fixed to the first wire section and extends from the first wire section toward the front and rear of the seat to form a portion that supports the front and rear of the extended pad section. Therefore, compared to, for example, a wire frame that includes wires fixed to the front and rear ends of the cushion pan in the seat-front-rear direction in addition to the configuration of the wire frame of the present invention, the increase in mass is suppressed.

[0010] Also, the claim described in claim 1 According to the configuration, for example, if a sub-assembly integrating the wire frame and bracket is manufactured, the wire frame can be fixed to the cushion pan simply by fixing the bracket of the sub-assembly to the cushion pan, thus simplifying the manufacturing process.

[0012] Also, the claim described in claim 2According to the configuration, the convex portion of the pad enters from above the seat into the space between the hanging portion at the front end of the cushion pan and the portion forming the front end of the wire frame, filling the space. Therefore, when the pad is covered with a surface covering, the convex portion prevents the surface covering from becoming recessed in the corresponding area between the hanging portion at the front end of the cushion pan and the portion forming the front end of the wire frame.

[0013] Claim 3 The vehicle seat of the present invention described in claim 2 In the configuration described above, the portion of the hanging part on the front end side of the cushion pan adjacent to the convex part is a curved corner hanging part that connects the front hanging part extending in the sheet width direction at the front end of the cushion pan and the side hanging part extending in the sheet front-rear direction at the side end of the cushion pan, and the position of the lower end of the convex part is set lower on the sheet side than the position of the lower end of the corner hanging part.

[0014] According to the above configuration, the portion of the cushion pan's front end that is adjacent to the convex portion is a curved corner section that connects the front end section extending along the seat width direction at the front end of the cushion pan with the side end section extending along the seat front-rear direction at the side end of the cushion pan. Here, the lower end of the convex portion is set lower on the seat than the lower end of the corner section, so the lower end of the convex portion prevents the occupant's hand from touching the lower end of the corner section. [Effects of the Invention]

[0015] As described above, the vehicle seat of the present invention has the excellent effect of suppressing mass increase in a configuration in which an extended portion is provided between the driver's seat and the passenger seat, extending from the seat cushion.

Mode for Carrying Out the Invention

[0017] A vehicle seat according to an embodiment of the present invention will be described with reference to FIGS. 1 to 5. In these figures, the arrow FR appropriately shown indicates the front side of the vehicle seat, the arrow UP indicates the upper side of the vehicle seat, and the arrow LH indicates the left side when facing the front of the vehicle seat. Hereinafter, when simply describing the front-rear, up-down, and left-right directions, unless otherwise specified, it shall indicate the front-rear of the vehicle seat, the up-down of the vehicle seat, and the left-right when facing the front of the vehicle seat. Also, in each figure, some reference numerals may be omitted for ease of viewing the drawing.

[0018] (Configuration of the Embodiment) In FIG. 1, a part of the interior of the passenger compartment 12 in which the vehicle seat 20 according to this embodiment is arranged is shown as a simplified plan view. The vehicle 10 on which the vehicle seat 20 is mounted is, for example, a light automobile. This vehicle seat 20 is configured to include a driver's seat 14 (one of the driver's seat and the passenger seat). A passenger seat 16 (the other of the driver's seat and the passenger seat) is arranged apart in the vehicle width direction on one side (here, the left side of the seat) of the driver's seat 14.

[0019] The driver's seat 14 of the vehicle seat 20 includes a seat cushion 22 that forms a seating portion on which an occupant sits and supports the buttocks and thighs of the seated occupant, a seat back 26 that supports the back of the seated occupant, and a headrest 28 that supports the head of the seated occupant. Further, the vehicle seat 20 of the present embodiment includes an extension portion 24 extending from the seat cushion 22 toward the passenger seat 16 side.

[0020] The extension portion 24 is arranged to fill the gap between the driver's seat 14 and the passenger seat 16 and constitutes the front center portion in the vehicle compartment 12. The extension portion 24 is configured to facilitate the seat change between the driver's seat 14 and the passenger seat 16. A gap G formed between the rear portion of the seat cushion 22 and the rear portion of the extension portion 24 is for arranging a buckle device (not shown) of the seat belt device.

[0021] FIG. 2 shows a perspective view of the seat cushion 22 and the extension portion 24 of the vehicle seat 20 in FIG. 1 as viewed obliquely from above the seat. FIG. 3 shows a perspective view of a cushion pan 40, a wire frame 60, etc. provided on the seat cushion 22 and the extension portion 24 (both referred to in FIG. 2).

[0022] The seat cushion 22 shown in FIG. 2 has a cushion pad portion 32 that is a cushion material, and a cushion pan 40 (see FIG. 3) that supports the cushion pad portion 32 from below the seat. The extension portion 24 has an extension pad portion 34 extending from the cushion pad portion 32 toward the passenger seat side (the left side of the seat, which is the other seat side), and a wire frame 60 (see FIG. 3) that supports the extension pad portion 34 from below the seat.

[0023] The extended pad portion 34 is molded integrally with the cushion pad portion 32 and extends to the vicinity of the passenger seat 16 (see Figure 1). The pad 30, which includes the cushion pad portion 32 and the extended pad portion 34, is made of a foam material such as urethane foam, and the surface of the pad 30 is covered with a skin 38. In Figure 2, the skin 38 is cut out to show the pad 30 (cushion pad portion 32 and extended pad portion 34) in order to facilitate understanding of the structure of the seat cushion 22 and the extended portion 24.

[0024] The cushion pan 40 shown in Figure 3 is formed by press-forming a metal plate (for example, a high-tensile steel plate). The cushion pan 40 is formed in a concave shape with a bottom wall portion 43 at the rear. Furthermore, the cushion pan 40 is basically formed symmetrically. The cushion pan 40 will be described in detail below.

[0025] The cushion pan 40 has a rear wall portion 44 that slopes towards the rear of the sheet from the rear end of the bottom wall portion 43 toward the upper side of the sheet, an intermediate inclined portion 42 that slopes towards the front of the sheet from the front end of the bottom wall portion 43 toward the upper side of the sheet, and a front general portion 41 that is continuous with the front end of the intermediate inclined portion 42 and is generally flat. The cushion pan 40 also has a lower side inclined portion 45 that slopes outward toward the upper side of the sheet from the outer ends in the sheet width direction of the bottom wall portion 43 and the intermediate inclined portion 42 toward the upper side of the sheet, a shelf-like portion 46 that extends outward toward the sheet width direction from the upper end of the lower side inclined portion 45, and an upper inclined portion 47 that slopes outward toward the upper side of the sheet width direction from the outer end of the shelf-like portion 46 toward the upper side of the sheet.

[0026] The cushion pan 40 has a fixed portion 48 that is formed as a base-like protrusion on a part of the outer side in the sheet width direction of the front general portion 41. The fixed portion 48 and the aforementioned shelf-like portion 46 are fixed to a side frame member (not shown) located below the sheet using fasteners B. In addition, an overhang portion 50 is formed at the outer end of the cushion pan 40 in the sheet width direction, extending outward in the sheet width direction from the front part in the front-rear direction of the sheet to the middle part in the front-rear direction of the sheet. The overhang portion 50 is connected via a step to the outer end in the sheet width direction of the portion formed by the rear part of the front general portion 41 and the fixed portion 48, and is also connected to the front upper end of the upper inclined portion 47.

[0027] In the cushion pan 40, a front end hanging portion 52 is formed by hanging down from the front end of the front general portion 41 toward the seat. The front end hanging portion 52 extends along the seat width direction at the front end of the cushion pan 40. A J-hook (not shown) sewn to the front end of the outer skin 38 (see Figure 2) is attached to the lower end of the front end hanging portion 52.

[0028] Furthermore, in the cushion pan 40, a side end hanging portion 56 is formed by hanging down from the outer end of the protruding portion 50 in the sheet width direction toward the lower side of the sheet. The side end hanging portion 56 extends along the front-rear direction of the sheet at the side end of the cushion pan 40. The front end hanging portion 52 and the side end hanging portion 56 are connected by a curved corner hanging portion 54 in a plan view. Note that the lower end 52L of the front end hanging portion 52 and the lower end 56L of the side end hanging portion 56 are set to be further downward from the sheet than the lower end 54L of the corner hanging portion 54.

[0029] Next, the wire frame 60 will be described. The wire frame 60 consists of a first wire section 62 which is fixed to the middle of the front-to-rear direction of the passenger side (left side of the seat) of the cushion pan 40 and extends in multiple directions toward the passenger side (left side of the seat) to form a protruding portion, and a second wire section 70 which is fixed to the first wire section 62 and extends from the first wire section 62 toward the front and rear sides of the seat.

[0030] The first wire section 62 is composed of two wires, 64 and 66, as an example. Wire 64 has a U-shape in plan view with the cushion pan 40 side open, extends along the sheet width direction, and is bent upward on the outer side in the sheet width direction. Wire 66 is joined from below to the center of the sheet in the front-rear direction of the outer end of wire 64 in the sheet width direction, and extends inward in the sheet width direction in plan view from the end joined to wire 64, and is bent in a crank shape so that the inner part in the sheet width direction is lower than the outer part in the sheet width direction. The inner end of wire 64 in the sheet width direction and the inner end of wire 66 in the sheet width direction are aligned in the sheet width direction and joined to the bracket 80.

[0031] The bracket 80 includes a wire fixing portion 80A to which the base end of the first wire portion 62 is joined, and the wire fixing portion 80A is bent downward from the inner end in the seat width direction and further bent inward in the seat width direction. The inner portion of the bracket 80 in the seat width direction is the seating portion 80B. The bracket 80 is welded to the cushion pan 40 with the wire fixing portion 80A resting on the left protruding portion 50 of the cushion pan 40 and the seating portion 80B resting on a part of the left side of the front general portion 41 of the cushion pan 40 and a part of the left shelf-like portion 46. In other words, the first wire portion 62 is fixed to the cushion pan 40 via the bracket 80.

[0032] The second wire section 70 forms the parts that support the front and rear of the extended pad section 34 (see Figure 2), and is shaped to match the shape of the extended pad section 34. This second wire section 70 includes a second wire front section 70A that constitutes the front part of the second wire section 70 in the seat-front-rear direction, and a second wire rear section 70B that constitutes the rear part of the second wire section 70 in the seat-front-rear direction.

[0033] The second wire front portion 70A is supported at the front of the first wire portion 62, and is formed below the first wire portion 62, with a portion that is further outward in the sheet width direction than the first wire portion 62 and a portion that is further forward of the sheet than the first wire portion 62. The second wire front portion 70A is composed of three wires 72, 73, and 74, as an example.

[0034] One end of wire 72 is joined from below to the front of the outer end in the sheet width direction of wire 64 of the first wire section 62. This wire 72 extends outward in the sheet width direction from the end joined to wire 64 and is bent at multiple points to form a three-dimensional shape. The other end of wire 72 is joined via wire 73 to the portion of the front end of wire 64 of the first wire section 62 that is closer to the outer side in the sheet width direction.

[0035] Wire 73 extends forward from one end joined to wire 64, with the other end of wire 72 joined to a portion of it. Its intermediate section is bent at multiple points, and its other end is joined to the outer and front portion of wire 72 in the sheet width direction. On the other hand, one end of wire 74 is joined to the front and inner portion of wire 72 in the sheet width direction, its intermediate section is bent at multiple points, and its other end is joined to the rear outer portion of wire 72 in the sheet width direction.

[0036] The portion 72A of the front part 70A of the second wire, which is the inner end in the seat width direction and forms the front end, is positioned spaced outward in the seat width direction from the corner hanging portion 54 of the cushion pan 40. Furthermore, the lower end 72B of the front end of the second wire front part 70A is set to be lower on the seat than the lower end of the corner hanging portion 54 of the cushion pan 40. Moreover, as an example, the lower end 72B of the front end of the second wire front part 70A is set to be slightly lower on the seat and slightly rearward on the seat than the lower end of the front hanging portion 52 of the cushion pan 40.

[0037] The second wire rear portion 70B is supported at the rear of the first wire portion 62, and is formed below the first wire portion 62, with a portion that is further outward in the seat width direction than the first wire portion 62 and a portion that is further rearward from the first wire portion 62. The second wire rear portion 70B is composed of two wires 76 and 78, as an example.

[0038] Wire 76 is joined from below at one end to the rear of the outer end in the sheet width direction of wire 64 of the first wire section 62. This wire 76 extends outward in the sheet width direction from the end joined to wire 64 and is bent at multiple points to form a three-dimensional shape. The other end of wire 76 is joined to the middle part in the sheet width direction of the rear end of wire 64 of the first wire section 62. On the other hand, wire 78 is joined at one end to the front part of wire 76 on the outer side in the sheet width direction, its middle part is bent at multiple points, and the other end is joined to the rear part of wire 76 on the inner side in the sheet width direction.

[0039] Next, the relationship between the front parts of the cushion pan 40 and wire frame 60 and the front part of the pad 30 will be explained with reference to Figures 4 and 5. Figure 4 shows the seat cushion 22 and extension 24 without the surface covering 38 (see Figure 2) as viewed from the front and diagonally downward side of the seat. Figure 5 shows the same state as in Figure 4 as viewed from the rear and diagonally downward side of the seat.

[0040] As shown in Figure 4, the front end 32F of the cushion pad portion 32 is positioned further forward of the seat than the front end hanging portion 52 of the cushion pan 40, and the lower end 32L of the front end of the cushion pad portion 32 is positioned higher on the seat than the lower end 52L of the front end hanging portion 52. On the other hand, as shown in Figures 4 and 5, the front end 34F of the extension pad portion 34 is formed continuously with the front end 32F of the cushion pad portion 32 and is positioned further forward of the seat than the wire frame 60, and the lower end 34L of the front end of the extension pad portion 34 is aligned with the lower end 72B of the front end of the wire frame 60 in the vertical direction of the seat.

[0041] As shown in Figure 5, the pad 30 has a convex portion 36 that is integrally formed with the cushion pad portion 32 and the extended pad portion 34. The convex portion 36 enters from above the sheet into the space between the corner hanging portion 54 that constitutes the hanging portion on the front end side of the cushion pan 40 and the portion that forms the front end side of the wire frame 60, and fills the space. As a result, the convex portion 36 is adjacent to the corner hanging portion 54 of the cushion pan 40. The position of the lower end 36L of the convex portion 36 is set lower on the sheet than the position of the lower end 54L of the corner hanging portion 54.

[0042] (Effects and mechanisms of the embodiment) Next, the operation and effects of this embodiment will be described.

[0043] The cushion pad portion 32 shown in Figure 2 is supported from below the seat by a cushion pan 40 (see Figure 3). An extension pad portion 34 extends from the cushion pad portion 32 towards the passenger side (left side of the seat), and this extension pad portion 34 is supported from below the seat by a wire frame 60 shown in Figure 3. Therefore, compared to, for example, a case where the extension pad portion is supported from below the seat by a panel-shaped pan, it is possible to suppress the increase in mass.

[0044] Here, the wire frame 60 is composed of a first wire section 62 and a second wire section 70. The first wire section 62 is fixed to the middle of the passenger side (left side of the seat) portion of the cushion pan 40 in the seat-front-rear direction and extends in multiple directions toward the passenger side (left side of the seat) to form an overhanging portion. The second wire section 70 is fixed to the first wire section 62 and extends from the first wire section 62 toward the front and rear of the seat to form a portion that supports the front and rear of the extended pad section 34 (see Figure 2). Therefore, compared to, for example, a wire frame that includes wires fixed to the front and rear ends of the cushion pan (40) in the seat-front-rear direction in addition to the configuration of the wire frame (60) of this embodiment, the increase in mass is suppressed.

[0045] As described above, the vehicle seat 20 shown in Figure 1 of this embodiment makes it possible to suppress mass increase in a configuration in which an extended portion 24 extending from the seat cushion 22 is provided between the driver's seat 14 and the passenger seat 16.

[0046] Furthermore, in this embodiment, as shown in Figure 3, the first wire section 62 is fixed to the cushion pan 40 via a bracket 80. With this configuration, if a sub-assembly integrating the wire frame 60 and the bracket 80 is manufactured, the wire frame 60 can be fixed to the cushion pan 40 simply by welding or otherwise fixing the bracket 80 of the sub-assembly to the cushion pan 40, thus simplifying manufacturing.

[0047] Furthermore, in this embodiment, as shown in Figure 5, the convex portion 36 of the pad 30 enters from above the sheet into the space between the corner hanging portion 54 of the cushion pan 40 and the portion forming the front end of the wire frame 60, filling the space. Therefore, when the surface material 38 (see Figure 2) is placed over the pad 30, the convex portion 36 can prevent the surface material 38 from becoming recessed in the area corresponding to the space between the corner hanging portion 54 of the cushion pan 40 and the portion forming the front end of the wire frame 60, thereby improving the appearance quality.

[0048] Furthermore, in this embodiment, the lower end 36L of the convex portion 36 is set lower on the seat side than the lower end 54L of the corner hanging portion 54. Therefore, the lower end of the convex portion 36 can prevent the occupant's hand from touching the lower end 54L of the corner hanging portion 54, eliminating the need to apply protective tape to the lower end 54L of the corner hanging portion 54.

[0049] (Supplementary explanation of the embodiment) In the above embodiment, the vehicle seat 20 shown in Figure 1 is configured to include the driver's seat 14. However, the vehicle seat of the present invention may also be applied to a vehicle seat configured to include a passenger seat with an extension extending toward the driver's seat.

[0050] Furthermore, in the above embodiment, the vehicle seat 20 shown in Figure 1 is a vehicle seat installed in a light vehicle, but the vehicle seat of the present invention may also be applied to vehicle seats installed in vehicles other than light vehicles.

[0051] Furthermore, in the above embodiment, as shown in Figure 3, the first wire portion 62 is fixed to the cushion pan 40 via the bracket 80. While this configuration is preferable from the viewpoint of facilitating manufacturing, as a modification of the above embodiment, a configuration in which the first wire portion (62) is directly fixed to the cushion pan (40) by welding or the like can also be adopted.

[0052] Furthermore, in the above embodiment, as shown in Figure 5, the pad 30 has a convex portion 36 that enters from above the sheet into the space between the corner hanging portion 54 of the cushion pan 40 and the portion forming the front end of the wire frame 60 and fills the space. While a configuration in which such a convex portion 36 is provided is preferred, a configuration in which the convex portion 36 is not provided is also possible.

[0053] Furthermore, in the above embodiment, the position of the lower end 36L of the convex portion 36 is set lower on the sheet than the position of the lower end 54L of the corner hanging portion 54, and such a configuration is preferred, but instead of adopting such a configuration, a configuration in which protective tape is applied to the lower end 54L of the corner hanging portion 54 can also be adopted.

[0054] Furthermore, the above embodiments and the various modifications described above can be combined as appropriate.

[0055] Although an example of the present invention has been described above, the present invention is not limited to the above, and it is of course possible to implement it in various modified forms without departing from its spirit. [Explanation of Symbols]
