Description

[Technical field]

[0001] The present invention relates to a vehicle seat and a method for manufacturing the vehicle seat, and more particularly to a vehicle seat having two connected seat members and a method for manufacturing the vehicle seat. [Background technology]

[0002] When a seat cushion having a cover is attached to a cushion frame, the rear end of the seat cushion is passed through a gap between a seat back and a rear pipe of the cushion frame (see Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2017-214067 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, since the size of the gap between the seat back and the rear pipe of the cushion frame is usually narrower than the height of the rear end of the seat cushion, when the rear end is inserted through the gap, it may hit the rear pipe and not pass through the gap. Therefore, when manufacturing vehicle seats, workers must insert the seat while holding the rear end to prevent it from hitting the rear pipe, which reduces workability.

[0005] Therefore, the present invention has been made in consideration of the above problems, and its object is to provide a vehicle seat and a method for manufacturing a vehicle seat in which a protrusion protruding from the end of the pad can be easily inserted between the skeletal frame and the seat member. [Means for solving the problem]

[0006] The above problem is solved by a vehicle seat according to the present invention, which is a vehicle seat having two connected seat members, each of the two seat members including a pad, a skin covering the pad, and a frame constituting the skeleton of the seat members, the pad of one of the seat members having a protruding portion disposed between the frame of the one of the seat members and the other of the seat members at a portion connected to the other of the seat members, the skin of the one of the seat members having a cylindrical body formed by an extension portion extending a predetermined distance from an end portion and covering a surface of the protruding portion, and a member joined to both sides of the extension portion and covering a part of the back surface of the protruding portion, The member covering a part of the rear surface of the protruding portion abuts against the frame of the one sheet member. This is solved by:

[0007] According to the vehicle seat of the present invention configured as described above, the protruding portion protruding from the end of the pad is covered by the extension portion and the grip portion. Therefore, when the protruding portion is passed through the gap, the protruding portion is prevented from hitting the frame, and the protruding portion can be easily inserted between the frame and the pad of the other seat member. Therefore, the workability when assembling the vehicle seat is improved.

[0008] In the above configuration, the member covering a portion of the rear surface of the protrusion may be a gripping portion that grips the protrusion. In the above configuration, both side portions of the extension portion and both side portions of the grip portion may be joined together, and the extension portion and the grip portion may form the cylindrical body. In the above configuration, the protrusion may be disposed to pass through the inside of the cylindrical body. 。 Ma In addition, in the above configuration, the one seat member is a seat cushion on which an occupant sits, and the other seat member is a seat back that is connected to a rear end of the seat cushion and supports the occupant's back, and the extension portion and the grip portion extend from a rear end of a cover of the seat cushion to cover the protruding portion of the seat cushion. With the above configuration, when the protrusion at the rear end of the seat cushion is passed between the frame of the seat cushion and the seat back, the protrusion is prevented from hitting the frame, for example a pipe member, and the protrusion can be easily passed between the frame and the seat cushion.

[0009] In the above configuration, the extension portion may have a thickness smaller than a thickness of the skin. By making the thickness of the extension portion extending from the skin thinner than the thickness of the skin, the manufacturing cost can be reduced even if the extension portion is made of the same material as the skin.

[0011] In the above configuration, the frame may have a pressure receiving portion that supports the pad, and an attachment portion that is fixed to the pressure receiving portion may be provided at an end of the skin. By providing an attachment portion at the end of the cover to be fixed to the pressure receiving portion, the pad can be easily fixed.

[0012] In the above configuration, a claw portion is formed on the frame or the pressure receiving portion, The attachment portion of the skin may be hooked onto the claw portion and fixed. By hooking the mounting part onto the claw portion and fixing it, the mounting part can be easily fixed to the frame or the pressure receiving part.

[0013] In the above configuration, the attachment portion may include a wire member that is hooked onto a plurality of the claw portions formed on the frame or the pressure-receiving portion. By hooking the wire member of the mounting part onto the claw portion, the mounting part can be fixed more easily and at a lower cost than, for example, a conventional mounting part formed in a hook shape. In the above configuration, it is preferable to include a headrest, a reclining mechanism, and a slide rail.

[0014] The above-mentioned problem is solved by a method for manufacturing a vehicle seat according to the present invention, which is a method for manufacturing a vehicle seat having two connected seat members, each of the two seat members including a pad, a skin covering the pad, and a frame constituting a skeleton of the seat members, the pad of one of the seat members having a protruding portion at a portion connected to the other seat member, the skin of the one of the seat members having a cylindrical body formed by an extension portion extending a predetermined distance from an end portion and covering a surface of the protruding portion, and a member joined to both sides of the extension portion and covering a portion of a back surface of the protruding portion, the method including a step of passing the protruding portion through the inside of the cylindrical body, and passing the protruding portion between the frame of the one of the seat members and the other of the seat members while the protruding portion is covered by the cylindrical body. The member covering a part of the rear surface of the protruding portion abuts against the frame of the one sheet member. This is solved by:

[0015] With the manufacturing method for a vehicle seat according to the present invention, the protruding portion protruding from the pad is covered by the extension portion and the gripping portion, thereby preventing the pad from hitting the frame and allowing the protruding portion to be easily inserted between the frame and another seat component, improving workability when assembling the vehicle seat.

[0016] Furthermore, in the above-mentioned method for manufacturing a vehicle seat, the frame may have a pressure-receiving portion that supports the pad, and the method may include a step of fixing the pad to the frame by hooking an attachment portion provided at an end of the skin onto a claw portion formed on the frame or the pressure-receiving portion. The pad can be easily fixed to the frame by hooking the attachment portion provided at the end of the cover onto the claw portion formed on the frame or the pressure receiving portion. Effect of the Invention

[0017] According to the vehicle seat of the present invention, the protruding portion protruding from the end of the pad is covered by the extension portion and the grip portion. This prevents the protruding portion from hitting the frame and allows the protruding portion to be easily inserted between the frame and the pad of another seat member. This improves the workability when assembling the vehicle seat. With the above configuration, when the protrusion at the rear end of the seat cushion is passed between the frame of the seat cushion and the seat back, the protrusion is prevented from hitting the frame, for example a pipe member, and the protrusion can be easily passed between the frame and the seat cushion. Furthermore, by making the thickness of the extension portion extending from the skin thinner than the thickness of the skin, the cost can be reduced even if the extension portion is made of the same material as the skin. In addition, since the protrusion passes through the inside of the cylindrical body formed by the extension portion and the gripping portion, the protrusion is prevented from shifting in the width direction of the vehicle seat when placed between the frame and the other seat component, making it easier to pass through. Furthermore, by providing an attachment portion at the end of the cover to be fixed to the pressure receiving portion, the pad can be easily fixed. Furthermore, by hooking the mounting portion onto the claw portion and fixing it, the mounting portion can be easily fixed to the frame or the pressure receiving portion. Furthermore, by hooking the wire member of the mounting portion onto the claw portion, the mounting portion can be fixed more easily and at a lower cost than, for example, a conventional mounting portion formed in a hook shape. In addition, with the manufacturing method for a vehicle seat according to the present invention, the protruding portion protruding from the pad is covered by the extension portion and the gripping portion, thereby preventing the pad from hitting the frame and allowing the protruding portion to be easily inserted between the frame and another seat component, improving workability when assembling the vehicle seat. Furthermore, the pad can be easily fixed to the frame by hooking the attachment portion provided at the end of the cover onto the claw portion formed on the frame or the pressure receiving portion.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0019] Hereinafter, the configuration of a vehicle seat according to one embodiment of the present invention (the present embodiment) will be described with reference to the drawings. However, the embodiment described below is an example for making the present invention easier to understand, and does not limit the present invention. In other words, the present invention can be modified and improved without departing from the spirit of the present invention, and of course, the present invention includes equivalents thereof.

[0020] In the following, a vehicle seat will be given as an example of a vehicle seat, and an example of the configuration will be described. However, the present invention is not limited to vehicle seats mounted on vehicles that run on ground and have wheels, such as automobiles and trains, and may also be seats mounted on aircraft, ships, and other vehicles that move on non-ground surfaces.

[0021] In the following description, the "front-rear direction" refers to the front-rear direction of the vehicle seat, which coincides with the direction of travel when the vehicle is traveling. The "seat width direction" refers to the width direction of the vehicle seat, which coincides with the left-right direction as seen by an occupant seated in the vehicle seat. The "up-down direction" refers to the up-down direction of the vehicle seat, which coincides with the vertical direction when the vehicle is traveling on a horizontal plane. In addition, in the following description, when various directions are described with the word "seat" added, such as "seat width direction" and "seat height direction", this indicates the direction relative to the vehicle seat, and when various directions are described with the word "vehicle" added, such as "inside of the vehicle" and "outside of the vehicle", this indicates the direction relative to the vehicle. In addition, the shapes, positions, postures, etc. of each part of the vehicle seat described below will be described assuming that the vehicle seat is in a seated state, which will be described later, unless otherwise specified.

[0022] <<Basic configuration of the vehicle seat according to the present embodiment>> The basic configuration of a vehicle seat according to this embodiment (hereinafter, vehicle seat S) will be described with reference to Fig. 1 and Fig. 2. Fig. 1 is a perspective view of the vehicle seat S. In Fig. 1, for convenience of illustration, a part of the vehicle seat S is illustrated with trim covers (cushion trim cover 17, back trim cover 27) removed.

[0023] The vehicle seat S is a seat that is placed on the vehicle body floor and in which a vehicle occupant sits. In this embodiment, the vehicle seat S is used as a front seat that corresponds to the front seat of the vehicle. However, the vehicle seat S is not limited to this, and may be a rear seat of the vehicle, and may also be used as a second-row middle seat or a third-row rear seat in a vehicle that has three rows of seats in the front-rear direction.

[0024] As shown in Fig. 1, the vehicle seat S mainly comprises a seat cushion S1 serving as a seating portion that supports the buttocks of a seated person, a seat back S2 serving as a backrest portion that supports the back of the seated person, and a headrest S3 disposed on the upper portion of the seat back S2 and supporting the head of the seated person. The seat cushion S1 corresponds to one seat member of the present invention, and the seat back S2 corresponds to the other seat member of the present invention. The seat cushion S1 and the seat back S2 are connected to each other with a reclining mechanism 60 sandwiched therebetween. Although not shown, a slide rail is provided on the lower portion of the seat cushion S1, and the slide rail allows the vehicle seat S to be placed on the vehicle floor in a state in which it can slide back and forth.

[0025] 2 is provided inside the vehicle seat S, and the seat frame F is mainly composed of a cushion frame 1 and a back frame 2. The cushion frame 1 forms the framework of the seat cushion S1 in the seat frame F, and the back frame 2 forms the framework of the seat back S2 in the seat frame F.

[0026] The rear end of the seat cushion S1 is connected to the lower end of the seat back S2. The seat cushion S1 is constructed by placing a cushion pad 16 on a cushion frame 1, and further covering the cushion pad 16 with a cushion trim cover 17. The seat back S2 is constructed by disposing a back pad 26 on a back frame 2, and further covering the back pad 26 with a back trim cover 27.

[0027] The cushion pad 16 and the back pad 26 are urethane base materials formed by foam molding using, for example, a urethane foaming agent. The cushion pad 16 and the back pad 26 correspond to the pads of the present invention. The cushion trim cover 17 and the back trim cover 27 correspond to the skin of the present invention, and are made of cloth, film, cloth, leather, sheet, etc., and are attached to cover the cushion pad 16 and the back pad 26 while being stretched with a predetermined tension. In this embodiment, when the cushion trim cover 17 is attached to the cushion pad 16, the ends of the cushion trim cover 17 are attached to predetermined locations, and the method of attachment will be described later.

[0028] In this embodiment, the cushion frame 1 has a substantially rectangular frame-like external shape as shown in Fig. 2. The cushion frame 1 mainly includes a pair of cushion side frames 12 constituting the left and right ends in the seat width direction, a pan frame 11 constituting the front end of the cushion frame 1, and a spring 14 (pressure receiving portion).

[0029] The two cushion side frames 12 are arranged to extend in the front-rear direction of the vehicle, spaced apart in the left-right direction, in order to define the width of the cushion frame 1. A front pipe 13a that connects the two cushion side frames 12 is attached to the front end, and a rear pipe 13b is attached to the rear end.

[0030] In addition, the pan frame 11 is fixedly joined to the front sides of the pair of cushion side frames 12, and the left and right cushion side frames 12 are connected at the front side by the pan frame 11. More specifically, the left and right ends of the pan frame 11 are fixed to flanges provided on the cushion side frames 12 by fixing means such as welding.

[0031] The pan frame 11 is intended to mainly support the thighs of a seated occupant (passenger), and is a frame formed from a metal plate material having a substantially flat upper surface and a generally rectangular shape.

[0032] A plurality of springs 14 (S springs) serving as pressure receivers are arranged in the seat width direction between the left and right cushion side frames 12. The springs 14 extend long in the seat front-rear direction. The front ends of the springs 14 are fixed to the front pipe 13a by engaging hooks 14c, and the rear ends of the springs 14 are fastened to the rear pipe 13b by engaging hooks 14d. The springs 14 are also provided with pressure receiver plates 14a.

[0033] The back frame 2 is mainly made of a pipe processed into a rectangular frame shape, and as shown in Fig. 2, the back frame 2 includes an inverted U-shaped upper frame 21, a pair of back side frames 22 forming the left and right ends in the seat width direction, and a lower frame 23 connecting the lower ends of the pair of back side frames 22. The back frame 2 is also provided with a pressure receiving plate 24 suspended from the back frame 2, and a suspension frame 25 for suspending the pressure receiving plate 24 is provided so as to span the left and right back side frames 22. A cylindrical headrest guide 21a is attached to the center of the upper end of the back frame 2. A headrest pillar 61 extending from the lower end of the headrest S3 is inserted into this headrest guide 21a, whereby the headrest S3 is attached to the seat back S2.

[0034] The components constituting the cushion frame 1 are made of materials having sufficient rigidity so as not to deform significantly when subjected to a load, such as metal materials such as steel and aluminum alloys. The components constituting the cushion frame 1 are joined together by welding, but bolts and adhesives may also be used in combination.

[0035] <<Cushion pad and cushion trim cover>> Next, the configurations of the cushion pad 16 and the cushion trim cover 17 will be described with reference to Fig. 3 to Fig. 5. In the following description, the "cushion front-rear direction" refers to the direction from the front end to the rear end of the seat cushion S1, which coincides with the front-rear direction of the vehicle seat S. In the cushion front-rear direction, the "front" refers to the side where the free end of the seat cushion S1 is located, and is not connected to the seat back S2.

[0036] As described above, the cushion pad 16 is a member that is placed on the cushion frame 1 and receives the buttocks of an occupant. In the seat cushion S1, the cushion pad 16 is provided so as to surround the cushion frame 1 that serves as a framework. In order to fix the cushion pad 16 to the cushion frame 1, the cushion pad 16 is covered with a cushion trim cover 17 and then inserted into a gap V between the seat back S2 and the rear pipe 13b of the cushion frame 1 (see FIG. 5). Therefore, the cushion pad 16 has a protruding portion 16a at the rear end of the cushion pad 16 that is inserted into the gap V. In other words, the cushion pad 16 has a protruding portion 16a that is disposed between the cushion frame 1 (more specifically, the rear pipe 13b) of the seat cushion S1 and the seat back S2 at a portion where the seat cushion S1 and the seat back S2 are connected.

[0037] The cushion trim cover 17 is a member that covers the cushion pad 16 of the seat cushion S1, and has a cover main body 17a and an extension portion 18. The cover main body 17a covers the upper surface, front surface, and both side surfaces of the cushion pad 16. As shown in FIG. 3, the extension portion 18 is provided at the rear end portion of the cushion trim cover 17, more specifically, at the rear end portion of the cover main body 17a, so as to extend rearward a predetermined distance L. The extension portion 18 covers the surface of the protruding portion 16a of the cushion pad 16.

[0038] When the cushion pad 16 is attached to the cushion frame 1, the extension 18 is inserted into the gap V together with the protrusion 16a, and the portion that extends beyond the rear pipe 13b is folded back and attached to the bottom surface side of the cushion pad 16 (see FIG. 5). More specifically, an attachment portion 18c is provided at the tip of the extension 18, and is attached to a claw portion 15c formed on the pressure-receiving plate 14a of the spring 14.

[0039] As shown in Figs. 4 and 5, the cushion trim cover 17 has a gripping portion 19 on the back side of the extension portion 18, which grips the protruding portion 16a and covers the back surface of the protruding portion 16a. The extension portion 18 extends from the cover body 17a and covers the surface of the protruding portion 16a. As shown in Figs. 4 to 6, both side portions of the extension portion 18 and both side portions of the gripping portion 19 are joined by sewing, and the extension portion 18 and the gripping portion 19 form a cylindrical body C. The protruding portion 16a of the cushion pad 16 is disposed to pass through the inside of the cylindrical body C.

[0040] A conventional cushion trim cover is not provided with a gripping portion 19 for gripping the protrusion 16a. Therefore, when attempting to pass the extension 18 and the protrusion 16a through the gap V, the protrusion 16a may hit the rear pipe 13b, and even if the extension 18 is pulled, the protrusion 16a may not pass through the gap V. Therefore, when attaching the cushion pad 16, the worker holds down the protrusion 16a to reduce the thickness of the protrusion 16a, and then inserts the extension 18 and the protrusion 16a into the gap V. Inserting the extension 18 and the protrusion 16a while holding down the protrusion 16a reduces workability.

[0041] In the cushion trim cover 17 (one of the seat members) used in the vehicle seat S of this embodiment, the gripping portion 19 grips the protruding portion 16a and covers the back surface, thereby suppressing the thickness of the protruding portion 16a. Therefore, when inserting the cushion pad 16 into the gap V, the worker can easily insert the protruding portion 16a of the cushion pad 16 into the gap V beyond the rear pipe 13b by simply pulling the extension portion 18 without holding the protruding portion 16a. In addition, after inserting the protruding portion 16a into the gap V, the worker folds back the extension portion 18 on the rear pipe 13b and hooks the attachment portion 18c (wire member 18d) of the end portion 18b onto the claw portion 15c provided on the back surface of the pressure-receiving plate 14a of the spring 14. This allows the cushion trim cover 17 and the cushion pad 16 to be attached to the cushion frame 1.

[0042] In this embodiment, as shown in Fig. 5, the thickness T1 of the extension 18 is formed to be thinner than the thickness T0 of the cover body 17a. By making the thickness T1 of the extension 18 thinner than the thickness T0 of the cover body 17a, the manufacturing cost can be reduced even if the extension 18 is made of the same material. In addition, when the extension 18 is passed through the gap V, the thinner the thickness, the easier it is to pass through.

[0043] Furthermore, as described above, by forming a cylindrical body C using the extension portion 18 and the gripping portion 19 and passing the protrusion portion 16a inside the cylindrical body C, the protrusion portion 16a is prevented from moving in the sheet width direction, and the protrusion portion 16a can be easily passed through the gap V without being misaligned.

[0044] 4, mounting portions 17c for mounting the cushion trim cover 17 to the cushion frame 1 are provided at the front and left and right end portions 17b of the cushion trim cover 17. The mounting portions 17c are realized by holding a wire member 17d at the end portion 17b of the cushion trim cover 17. The wire member 17d exposed from a cut-out portion at the end portion 17b is hooked onto claw portions 15a, 15b provided on the pair of cushion side frames 12 and the pan frame 11, whereby the mounting portions 17c are fixed to the cushion frame 1.

[0045] The wire member 17d is preferably a metal or resin wire having a rod-like, linear, tubular shape, etc. The diameter of the wire member 17d is preferably 1 to 8 mm, and more preferably 1.5 to 5 mm. The mounting portion 17c is formed by folding back the end portions 17b of the cushion trim cover 17 and sewing them together to form a bag shape, and then passing the wire member 17d through the bag and storing it therein. The wire member 17d is then hooked to the positions of the claw portions 15a and 15b formed on the cushion side frame 12 and the pan frame 11, which will be described later, to fix the cushion trim cover 17 to the cushion pad 16 with a predetermined tension.

[0046] 7, the cushion frame 1 is formed with a plurality of claws 15a, 15b for fixing the mounting portion 17c of the cushion trim cover 17. In this embodiment, the claws 15a are formed at four locations on the bottom surface of the pan frame 11 by cutting and raising the claws having an L-shaped cross section, and the mounting portion 17c provided on the front end of the cushion trim cover 17 is hooked onto the claws.

[0047] Furthermore, two claw portions 15b having an L-shaped cross section are attached by welding to each of the left and right cushion side frames 12. Mounting portions 17c provided on the left and right ends of the cushion trim cover 17 are adapted to be hooked onto the claw portions 15b. A claw portion 15c is formed by cutting and raising on the bottom surface of the pressure-receiving plate 14a of the spring 14 provided on the cushion frame 1. A mounting portion 18c (wire member 18d) provided on the end portion 18b of the extension portion 18 folded back by the rear pipe 13b is hooked onto the claw portion 15c.

[0048] The cushion pad 16 covered with the cushion trim cover 17 is placed on the cushion frame 1, and the cushion pad 16 can be fixed by hooking the wire members 17d, 18d on the ends 17b, 18b onto the claw portions 15a to 15c provided on the cushion frame 1, thereby making it easy to fix the cushion pad 16 to the cushion frame 1.

[0049] A manufacturing method of the vehicle seat S of this embodiment will be described with reference to Fig. 8. It is assumed that the seat frame F shown in Fig. 2 is prepared in advance, the back pad 26 is arranged on the seat frame F, and the back trim cover 27 for covering the back pad 26 is attached (S101).

[0050] A cushion pad 16 having a protruding portion 16a at its rear end, and a cushion trim cover 17 having an extension portion 18 and a grip portion 19 are prepared (S102). A cylindrical body C consisting of the extension portion 18 and the grip portion 19 is turned upside down, and the protruding portion 16a is passed through the turned-up cylindrical body C. Then, the cylindrical body C is returned to its original state, and the protruding portion 16a is covered with the extension portion 18 and the grip portion 19 (S103).

[0051] The cushion pad 16 covered with the cushion trim cover 17 is placed on the cushion frame 1, and the protruding portion 16a of the cushion pad 16, the extension portion 18 covering the protruding portion 16a, and the grip portion 19 are passed through the gap V between the rear pipe 13b and the seat back S2 (S104). After the protruding portion 16a is sandwiched between the rear pipe 13b and the seat back S2, the extension portion 18 of the cushion trim cover 17 is folded back by the rear pipe 13b, and the mounting portion 18c of the extension portion 18 is disposed on the bottom of the pressure receiving plate 14a. Next, the wire members 17d, 18d of the mounting portions 17c, 18c provided at the ends of the cushion trim cover 17 are hooked onto the claw portions 15a to 15c provided on the cushion frame 1 and the pressure receiving plate 14a of the spring 14. The cushion pad 16 covered with the cushion trim cover 17 is attached to the cushion frame 1, and the vehicle seat S is completed (S105).

[0052] The vehicle seat and the manufacturing method thereof according to the present embodiment have been described above with reference to the drawings. In the above embodiment, the seat cushion S1 having the protruding portion 16a passing between the seat back S2 and the cushion frame 1 has been described. However, this is only an example, and the present invention may be applied to the seat back S2. That is, a protruding portion extending downward may be provided at the lower end of the back pad 26 of the seat back S2, and the protruding portion may be disposed between the lower frame 23 of the back frame 2 and the seat cushion S1. The protruding portion is covered by an extension portion and a grip portion extending from the lower end of the back trim cover, so that the protruding portion is not pressed when the protruding portion of the seat back S2 is inserted, improving the workability of assembly.
