Description

Technical Field

[0001] This invention relates to a seat cushion. More specifically, it relates to a seat cushion having a cushion body that elastically supports a seated person and a seat frame that supports the cushion body from the back of the seat. Background Technology

[0002] Patent Document 1 discloses a segmented seat that elastically supports the seated person and is composed of three segmented elements: a main body of the top plate constituting the central part in the width direction of the seat and side portions of the top plate constituting the two side parts in the width direction of the seat.

[0003] Existing technical documents

[0004] Patent Document 1: Japanese Patent Application Publication No. 2020-33005 Summary of the Invention

[0005] The problem that the invention aims to solve

[0006] In the case of a mechanism for adjusting the cushion length of a seat cushion in a segmented seat arrangement as described in Patent Document 1, a structure in which the front part of the main body of the headliner moves forward relative to the rear part of the headliner is considered. In this case, when the front part of the main body of the headliner extends forward relative to the side part of the headliner, foreign objects can get stuck between them from the side, which is not preferable. Therefore, the present invention provides a seat cushion that can suppress the getting of foreign objects even when a variable cushion length mechanism is provided in the main body of the headliner that is separated from the side part of the headliner.

[0007] Methods for solving problems

[0008] As a means of solving the above-mentioned problems, the seat cushion of the present invention adopts the following means.

[0009] That is, the first technical solution of the present invention is a seat cushion, comprising: a cushion body that elastically supports a seated person; and a seat frame that supports the cushion body from the back of the seat. The cushion body is composed of three dividing elements: a top plate main body that constitutes the central portion in the width direction of the seat and top plate side portions that constitute the two side portions in the width direction of the seat. The seat frame has: a frame front portion, which supports the front portion of the top plate main body from the back of the seat, i.e., the main body front portion; and a frame rear portion, which supports the rear portion of the top plate main body from the back of the seat, i.e., the main body rear portion, and each of the top plate side portions. The seat cushion also has: a cushion length variable mechanism that extends the cushion length of the top plate main body by moving the frame front portion relative to the frame rear portion forward of the seat; and a first protrusion that extends from one of the frame front portion and the frame rear portion to the other and covers the gap formed between the two portions as the cushion length extends.

[0010] According to the first technical solution, a first protrusion extending from the front or rear of the frame covers the gap formed by the elongation of the seat cushion from the side in a planar manner. Therefore, even if the seat cushion length of the main body of the top plate, which is separated from the side of the top plate, is changed, it is possible to prevent foreign objects from getting stuck between the front and rear parts of the main body from the side.

[0011] The second technical solution of the present invention is based on the first technical solution described above. The main body of the top plate has a main pad that constitutes a seat pad and a main substrate that is installed on the back of the pad of the main pad. The first protrusion is provided at the rear of the frame in a manner that extends forward toward the seat. A second protrusion is provided at the front of the substrate that constitutes the front of the main body of the main substrate. The second protrusion extends backward toward the seat from the side together with the first protrusion in a manner that covers the gap in a planar manner.

[0012] According to the second technical solution, foreign objects can be more appropriately prevented from getting stuck between the front and rear parts of the main body from the side by means of both the first protrusion extending from the rear of the frame to the front of the seat and the second protrusion extending from the front of the substrate to the rear of the seat.

[0013] The third technical solution of the present invention, based on the first technical solution, further includes a main body portion of the top plate that constitutes a seat cushion and a main cover that covers the main body cushion from the surface of the seat. The main cover has a side surface portion that covers the main body cushion from the side in a planar manner and a side cover portion that has the gap provided by the first protrusion.

[0014] According to the third technical solution, the side cover portion becomes a structure supported from the back side of the cover by the first protrusion portion. Therefore, the "tension" supported by the side cover portion abutting against the first protrusion portion can suppress the insertion of foreign objects within a large range of the side cover portion's extension.

[0015] The fourth technical solution of the present invention is based on the third technical solution described above, wherein the main body cover has a back cover member disposed on the back side of the cover in an overlapping manner.

[0016] According to the fourth technical solution, the rigidity of the side cover can be increased, thereby more effectively preventing foreign objects from getting stuck through the side cover. Attached Figure Description

[0027] The following description uses the accompanying drawings to illustrate the methods for carrying out the present invention.

[0028] First Implementation Method

[0029] (Simplified structure of seat cushion 1)

[0030] First, use Figures 1-8 The structure of the seat cushion 1 according to the first embodiment of the present invention will now be described. Furthermore, in the following description, when referring to directions such as front-back, up-down, left-right, etc., it refers to the directions shown in the respective figures.

[0031] Furthermore, when "seat" is used to indicate directions such as "seat width direction," it refers to each direction based on the seat cushion 1. Additionally, in the following description, where no specific reference numeral is shown, or where there is no corresponding reference numeral in the reference numerals, please refer appropriately. Figures 1-8 Any one of the graphs in the image.

[0032] like Figure 1 As shown, the seat cushion 1 of this embodiment is configured as the seating portion of a car seat. Figures 1-2 As shown, the seat cushion 1 has a cushion body 2 that elastically supports the buttocks and thighs of the occupant, and a metal cushion frame 5 that supports the cushion body 2 from the back of the seat (lower side of the figure).

[0033] The seat cushion 2 is structured into three parts: a main top plate 3 forming the central portion in the width direction of the seat, and side top plate portions 4 forming the two side portions in the width direction of the seat. By dividing the seat cushion 2 in this way, it is possible to replace the parts of each part with the corresponding specifications.

[0034] like Figure 2 As shown, these headboard main bodies 3 and each headboard side body 4 are individually assembled to the seat cushion frame 5 from the seat surface (top side of the illustration). The headboard main body 3 has a main body pad 3A made of polyurethane foam and a main body substrate 3B made of resin assembled to the main body pad 3A in a manner that abuts against the back side of the pad.

[0035] Additionally, the top plate main body 3 has a fabric main cover 3C that covers the main body pad 3A. The main cover 3C covers the main body pad 3A from the surface side of the pad (upper side in the figure). The cover ends of the main cover 3C, which are the rear and left and right peripheral edges, are pulled into the back side of the main body substrate 3B (lower side in the figure) and fixed to the peripheral edge of the substrate.

[0036] Thus, the main body cover 3C is integrated with the main body substrate 3B by enclosing the main body pad 3A between itself and the main body substrate 3B. As a result, the main body substrate 3B is fixed in a state where it abuts against the back of the pad of the main body pad 3A via the main body cover 3C.

[0037] The main body of the top plate 3 is assembled to the seat cushion frame 5 in a manner in which the main body pad 3A, the main body substrate 3B, and the main body cover 3C are assembled as a single unit. Specifically, the main body of the top plate 3 is mounted such that its main body substrate 3B abuts against the seat cushion frame 5 from the seat surface and is fastened as a single unit by clips or bolts not shown.

[0038] In addition, the main body of the top plate 3 is pulled in and hooked to the back side of the seat frame 5 (see lower side of the figure) by the end of the cover on the front side of its main body cover 3C and thus fixed to the seat frame 5.

[0039] The seat cushion frame 5 has: a frame front portion 5D, which supports the front portion of the main body 3 of the top plate 3 from the back of the seat, i.e., the main body front portion 31; and a frame rear portion 5E, which supports the rear portion of the main body 3 of the top plate 3 from the back of the seat, i.e., the main body rear portion 32, and each top plate side portion 4. Specifically, the frame rear portion 5E has a pair of lower arms E1 on the left and right sides that form a skeleton along the left and right sides of the seat cushion 1.

[0040] Additionally, the rear frame portion 5E includes: a front tube E2 integrally mounted between the front portions of each lower arm E1; and a rear tube E3 integrally mounted between the rear portions of each lower arm E1. Furthermore, the rear frame portion 5E includes an inclined panel E4 positioned between the front portions of each lower arm E1 such that the panel surface faces the seat height direction.

[0041] Inclined side panels E5 are attached to the left and right sides of the inclined panel E4, extending above the upper parts of each lower arm E1. The inclined panel E4 is connected to each inclined arm E6 extending from the inclined side panels E5 to the rear of the seat in a manner that allows it to rotate relative to each lower arm E1 about an axis extending along the width of the seat.

[0042] Thus, the tilting panel E4 can adjust its seat angle relative to each lower arm E1 by rotating about an axis extending along the width direction of the seat, driven by a drive unit (not shown) connected to each lower arm E1. A frame front portion 5D is located at the front of the tilting panel E4.

[0043] like Figure 3 As shown, the seat cushion 1 also has a cushion length variable mechanism 6, which extends the cushion length by moving the front part 5D of the frame relative to the inclined panel E4 towards the front of the seat. The cushion length variable mechanism 6 has a pair of left and right sliding tubes 6A connected to the bottom of the inclined panel E4 in a manner that allows them to slide along the front-back direction of the seat.

[0044] Each sliding tube 6A is constructed of a round tube extending straight in the front-rear direction of the seat. The front end of each sliding tube 6A is welded to the bottom of each support bracket D1, which is welded to the back of the top plate of the front part 5D of the frame and is bent in a U-shape from the front view. Each support bracket D1 is positioned inside the seat width direction of each first protrusion E7, which extends from each inclined side panel E5 toward the front of the seat.

[0045] Each sliding tube 6A moves relative to the tilt panel E4 in the seat's fore-and-aft direction, driven by a drive unit (not shown) connected to the bottom of the tilt panel E4. As a result, the position of the front part 5D of the frame relative to the tilt panel E4 in the seat's fore-and-aft direction is adjusted.

[0046] By pulling the front part 5D of the frame out from the inclined panel E4 toward the front of the seat, the front part 31 of the main body located above it (see reference) Figure 2 The main body 32, located at the upper part of the inclined panel E4, is pulled out towards the front of the seat. As a result, the seat cushion length of the main body 3 of the top panel is extended.

[0047] Reference Figure 2The main body pad 3A constituting the main body part 3 is divided into two parts: a front pad A1 located on the upper part of the front part 5D of the frame and a rear pad A2 located on the upper part of the rear part 5E of the frame. Similarly, the main body substrate 3B is divided into two parts: a front substrate B1 that abuts against the back of the front pad A1 and a rear substrate B2 that abuts against the back of the rear pad A2. The front substrate B1 is fixed to the upper part of the front part 5D of the frame. The rear substrate B2 is fixed to the upper part of the rear part 5E of the frame.

[0048] The main cover 3C covers the pad from the surface side (top of the illustration) across the front portion A1 and the rear portion A2 of the pad. Furthermore, before the seat cushion length is extended, the portion of the main cover 3C covering the area between the front portion A1 and the rear portion A2 of the pad is pulled downwards from between them and held in place.

[0049] As the front portion A1 of the cushion is pulled forward towards the seat, the main cover 3C is pulled out in such a way that the portion pulled between the front portion A1 and the rear portion A2 of the cushion extends between them. Thus, the main cover 3C is positioned between the front portion A1 and the rear portion A2 of the cushion as it is pulled forward towards the seat. Furthermore, as the front portion A1 of the cushion returns to the rear of the seat, the main cover 3C is pulled back between the front portion A1 and the rear portion A2 of the cushion.

[0050] like Figure 3 As shown, each inclined side panel E5, which is connected to the left and right sides of the inclined panel E4 described above, has a first protrusion E7 in the shape of a vertical plate extending forward toward the seat. Each first protrusion E7 is formed in a shape that is symmetrical to each other. Each first protrusion E7 extends forward toward the seat than the inclined panel E4, and is formed in a vertical plate shape with its panel surface facing the width direction of the seat.

[0051] Each first protrusion E7 is positioned lower than the top plate of the front part 5D of the frame, which is shaped like an inverted L in side view, and higher than the lower edge of the front part 5D of the frame. For example... Figures 4-5 As shown, each first protrusion E7 is configured to extend directly below the top plate of the front part 5D of the frame before the seat cushion length is extended.

[0052] In this state, each first protrusion E7 is arranged to enter the inner side of the left and right protruding surfaces of the front portion B1 of the substrate assembled to the front portion 5D of the frame, i.e., the inner side of each second protrusion B3. The front portion B1 of the substrate has the following structure: it is formed into an inverted L-shaped plate covering the top plate and the front plate of the front portion 5D of the frame, and has each second protrusion B3 extending from the side edges in a way that covers the inner corner portion of the inverted L-shape in a planar manner.

[0053] Each second extension B3 is shaped as a vertical plate extending from the left and right side edges of the front panel of the front part 5D of the frame towards the rear of the seat. More specifically, each second extension B3 is shaped as a vertical plate with its panel surface facing the width direction of the seat. Each second extension B3 extends towards the rear of the seat to a position approximately equal to the rear edge of the top plate of the front part 5D of the frame.

[0054] Before the seat cushion length is extended, each of the second protrusions B3 overlaps with each of the first protrusions E7 in the fore-and-aft direction of the seat. Specifically, each of the second protrusions B3 covers the corresponding first protrusion E7 in a planar manner from the outer side in the width direction of the seat.

[0055] like Figures 6-7 As shown, each first protrusion E7 extends forward along with the length of the seat cushion and gradually separates from each second protrusion B3, which moves towards the front of the seat, towards the rear of the seat. Thus, each first protrusion E7 becomes a state in which it covers the gap T formed between each inclined side panel E5 and the front part of the frame 5D (each second protrusion B3 of the base material front part B1 assembled to the front part of the frame 5D) from the side in a planar manner.

[0056] As a result, the lateral coverage by each first protrusion E7 and each second protrusion B3 prevents foreign objects from entering between the front part 31 and the rear part 32 of the main body from the side. Figure 8 As shown, in detail, each of the first protrusions E7 and each of the second protrusions B3 is configured to have a side cover C1 covering the outer side of the main body cover 3C.

[0057] Each side cover C1 covers from the side. Figure 2 The main body pad 3A shown includes the front part A1 and the rear part A2 of the pad. Thus, even if a load such as pressing a foreign object from the outside is applied to each side cover C1, each side cover C1 is supported from the back cover side (inner side in the seat width direction) by each first protrusion E7 and each second protrusion B3.

[0058] As a result, it is possible to prevent foreign objects from entering between the front part 31 and the rear part 32 of the main body from the side. A planar back part C2 made of the same material as the side cover C1 is integrally laminated on the back of the cover of each side cover C1.

[0059] Thus, each side cover portion C1 is reinforced by each back cover member C2 in a manner that appropriately increases surface rigidity (hardness). As a result, even if an outward pressing load is applied to the portion of the gap T between each first protrusion E7 and each second protrusion B3 covering each side cover portion C1, each side cover portion C1 will not easily flex between them due to the "tension" of its contact with each first protrusion E7 and each second protrusion B3.

[0060] Alternatively, each back panel C2 can be made of a different material than the side cover C1, such as felt or non-woven fabric. Alternatively, each back panel C2 can be made of resin board.

[0061] In summary, the seat cushion 1 of this embodiment has the following configuration. Furthermore, the reference numerals marked in parentheses below correspond to the structures shown in the above embodiments.

[0062] That is, the seat cushion (1) has: a cushion body (2) that elastically supports the seated person; and a seat frame (5) that supports the cushion body (2) from the back of the seat. The cushion body (2) is composed of three dividing elements: a main body (3) of the top plate that forms the central part in the width direction of the seat and each side part (4) of the top plate that forms the two sides in the width direction of the seat. The seat frame (5) has: a frame front part (5D) that supports the front part of the main body (3) from the back of the seat, i.e., the main body front part (31); and a frame rear part (5E) that supports the rear part of the main body (3) from the back of the seat, i.e., the main body rear part (32) and each side part (4).

[0063] The seat cushion (1) also has a cushion length variable mechanism (6), which extends the cushion length of the headboard body (3) by moving the front part (5D) of the frame relative to the rear part (5E) of the frame forward. In addition, the seat cushion (1) also has a first protrusion (E7), which extends from one of the front part (5D) and the rear part (5E) of the frame toward the other (5D) and covers the gap (T) formed between one (5E) and the other (5D) with the extension of the cushion length from the side.

[0064] According to the above structure, the gap (T) formed by the elongation of the seat cushion length is covered from the side by the first protrusion (E7) extending from the front part (5D) or the rear part (5E) of the frame in a planar manner. Thus, even if the seat cushion length of the main body part (3) of the top plate, which is separated from the side part (4) of the top plate, is changed, it is possible to prevent foreign objects from getting stuck between the front part (31) and the rear part (32) of the main body from the side.

[0065] In addition, the main body of the top plate (3) has a main body pad (3A) that constitutes the seat pad and a main body substrate (3B) that is installed on the back of the pad of the main body pad (3A). A first protrusion (E7) is provided at the rear of the frame (5E) in such a way that it extends forward toward the seat. A second protrusion (B3) is provided at the front part (B1) of the substrate of the main body front part (31) that constitutes the main body substrate (3B), and the second protrusion (B3) extends backward toward the seat from the side together with the first protrusion (E7) in such a way that it covers the gap (T) in a planar manner.

[0066] According to the above structure, foreign objects can be more appropriately prevented from getting stuck between the front part (31) and the rear part (32) of the main body by means of the first protrusion (E7) extending from the rear part (5E) of the frame to the front of the seat and the second protrusion (B3) extending from the front part (B1) of the base material to the rear of the seat.

[0067] In addition, the main body of the top plate (3) also has a main body pad (3A) that constitutes the seat pad and a main body cover (3C) that covers the main body pad (3A) from the seat surface. The main body cover (3C) has a pad side that covers the main body pad (3A) from the side in a planar manner and a side cover part (C1) with a gap (T) having a first protrusion (E7).

[0068] According to the above structure, the side cover (C1) is supported from the back side by the first protrusion (E7). Therefore, the tension supported by the contact between the side cover (C1) and the first protrusion (E7) can suppress the insertion of foreign objects within a large range of the side cover (C1).

[0069] In addition, the main cover (3C) has a back cover member (C2) that overlaps with the back cover of the side cover (C1). According to the above structure, the rigidity of the side cover (C1) can be improved, and the insertion of foreign objects through the side cover (C1) can be more appropriately suppressed.

[0070] Second Implementation Method

[0071] Next, use Figure 9 The structure of the seat cushion 1 according to the second embodiment of the present invention will be described. In the seat cushion 1 of this embodiment, each first protrusion E8, which covers the gap T between each inclined side panel E5 and the front part of the frame 5D (each second protrusion B3 of the base material front part B1 assembled to the front part of the frame 5D) when the length of the cushion is extended, is configured as follows.

[0072] That is, each first protrusion E8 and each inclined side panel E5 are composed of different components. Each first protrusion E8 is integrally joined to each inclined side panel E5 by welding. Thus, each first protrusion E8 and each first protrusion E7 shown in the first embodiment (refer to...) Figure 3 Similarly, it is configured to extend from each inclined side panel E5 towards the front of the seat. The structure other than that described above is the same as that shown in the first embodiment, therefore the same reference numerals are used and descriptions are omitted.

[0073] Third Implementation Method

[0074] Next, use Figure 10The structure of the seat cushion 1 according to the third embodiment of the present invention will be described. In the seat cushion 1 of this embodiment, each first protrusion E9, which covers the gap T between each inclined side panel E5 and the front part of the frame 5D (each second protrusion B3 of the base material front part B1 assembled to the front part of the frame 5D) when the length of the cushion is extended, is configured as follows.

[0075] That is, each first protrusion E9 and each inclined side panel E5 are composed of different components. Each first protrusion E9 is integrally joined to each side edge of the inclined panel E4 by welding. Thus, each first protrusion E9 and each first protrusion E7 shown in the first embodiment (see reference) Figure 3 Similarly, it is configured to extend from each inclined side panel E5 towards the front of the seat. The structure other than that described above is the same as that shown in the first embodiment, therefore the same reference numerals are used and descriptions are omitted.
