Description

[0001] This application is a divisional application of the patent application with the application number 201880064674.4 (PCT / JP2018 / 007689). Technical Field

[0002] The present invention relates to a seat for a vehicle, and more particularly to a seat for a vehicle having a side support portion on the side of a back support portion that supports the back of a seated person. Background Art

[0003] A vehicle seat having a side support portion on the side of a back support portion that supports the back of a seated person is already well known. For example, the seat described in Patent Document 1. In the seat described in Patent Document 1, the side support portion (labeled "seat back side portion" in Patent Document 1) is composed of a resin base member (labeled "seat back side portion main body" in Patent Document 1) and a skin that covers the base member (labeled "skin material" in Patent Document 1).

[0004] Patent Document 1: Japanese Unexamined Patent Application Publication No. 2015-137021 Summary of the Invention

[0005] However, the side support portion has a good appearance because the skin, which is a component thereof, is appropriately stretched. In particular, when a plurality of skin pieces are joined to form the skin, the appearance of the joined portion of the skin pieces is important in terms of the quality of the vehicle seat.

[0006] Therefore, the present invention has been made in view of the above problems, and an object thereof is to provide a vehicle seat having a side support portion with a good appearance.

[0007] The above problem is solved by the following means. A vehicle seat according to the present invention includes a back support portion that supports the back of a seated person, and a side support portion located on the side of the back support portion. The side support portion includes a base member that defines the outer shape of the side support portion, and a skin that covers the base member and forms the outer surface of the side support portion. The skin includes a plurality of skin pieces that are joined to each other to form the skin, and an extension portion that extends from the joined portion of the skin pieces on the inner side of the skin. In a state where the skin covers the base member, the extension portion is pulled toward the opposite side of the side where the joined portion of the skin pieces is located with respect to the base member.

[0008] In the vehicle seat of the present invention configured as described above, the extension portion attached to the joined portion of the skin pieces in the skin is pulled toward the inner side of the base member. Accordingly, the joined portion of the skin pieces is appropriately stretched. As a result, the side support portion has a good appearance.

[0009] In addition, in the seat for a vehicle of the present invention, it is preferable that the extension portion is a belt-like body, a slit hole is provided in the base member, and in a state where the skin covers the base member, the belt-like body passes through the slit hole and is pulled relative to the base member to the side opposite to the side where the portion joined to the skin piece is located.

[0010] In the above configuration, the belt-like body as the extension portion passes through the slit hole provided in the base member and is stretched. Accordingly, compared with a configuration in which the belt-like body is hung on the outer edge portion of the base member and stretched, the length of the belt-like body can be made shorter.

[0011] In addition, in the seat for a vehicle of the present invention, it is preferable that a plurality of the skin pieces are joined by sewing, and at the portion where the skin pieces are joined, the extension portion is sewn together with the plurality of skin pieces.

[0012] In the above configuration, since the extension portion is sewn together with the plurality of skin pieces, the sewing of the extension portion and the plurality of skin pieces can be performed together. As a result, the installation of the extension portion can be effectively performed.

[0013] In addition, in the seat for a vehicle of the present invention, it is preferable that a plurality of the belt-like bodies are provided along the portion where the skin pieces are joined, and one slit hole is provided in the base member for each of the plurality of belt-like bodies.

[0014] In the above embodiment, a slit hole through which the belt-like body passes is provided for each belt-like body (individually). If such a configuration is adopted, compared with a case where a relatively large slit hole through which all the belt-like bodies can pass is provided between the belt-like bodies as a common slit hole, a reduction in the strength of the base member accompanying the formation of the slit hole can be suppressed, and at the same time, the belt-like body can appropriately pass through the slit hole.

[0015] In addition, in the seat for a vehicle of the present invention, it is preferable that, in a state where the skin covers the base member, the portion of the belt-like body installed on the inner side of the skin and the portion of the base member where the slit hole is provided are juxtaposed so as to overlap each other.

[0016] If the above configuration is adopted, since the slit hole is arranged at a position juxtaposed with the belt-like body, the belt-like body can easily pass through the slit hole, and at the same time, the length of the belt-like body can be made shorter.

[0017] In addition, in the seat for a vehicle of the present invention, it is preferable that the extension portion is made of a material having lower extensibility than the material of the skin piece.

[0018] If the above configuration is adopted, since the extension portion is stabilized in the stretched state, the state where the portion where the skin pieces are joined in the skin is stretched can be appropriately maintained. As a result, the appearance of the side support portion can be made better.

[0019] In addition, in the passenger seat of the present invention, it is preferred that a groove portion is formed on the surface of the base component into which the portion to which the skin sheet is joined enters, and when the skin sheet covers the base component, the base portion of the extension portion installed on the portion to which the skin sheet is joined is arranged in the groove portion.

[0020] The portion of the skin attached to the base of the extension, that is, the portion where the skin sheet is joined, is thicker than the other portions. In the above configuration, the portion where the skin sheet is joined can be accommodated in the groove, thereby making the thicker portion of the skin less noticeable.

[0021] In addition, in the passenger seat of the present invention, it is preferred that the plurality of leather sheets include a first leather sheet located on one end side and a second leather sheet located on the other end side in the width direction of the passenger seat, and the base portion of the extension portion installed on the portion where the leather sheets are joined is installed on the portion where the leather sheets are joined while being connected to the first leather sheet, and the free end portion of the extension portion located on the opposite side of the base portion passes through the slit hole and engages with a portion of the base portion that is closer to the first leather sheet than the second leather sheet.

[0022] In the above configuration, the base portion of the extension portion and the free end portion of the extension portion are provided near the first surface sheet in the width direction of the vehicle seat.

[0023] In addition, in the passenger seat of the present invention, it is preferred that the opening of the slit hole is toward one end side in the width direction of the passenger seat, and in the extension portion, the free end portion located on the opposite side of the base portion where the skin sheet is joined extends out of the slit hole through the opening and is hung on one end portion of the base portion in the width direction.

[0024] In the above configuration, the free end of the extension extends out of the slit through the opening of the slit and is hooked on the end of the base member on the same side of the opening.

[0025] In addition, in the passenger seat of the present invention, it is preferred that a claw portion and a protrusion portion are provided on the inside of the base component, and the free end portion of the extension portion located on the opposite side of the base portion of the portion connected to the surface sheet is hung on the claw portion; the protrusion portion protrudes more than the claw portion, and engages or abuts with a part of the vehicle body when the side support portion is mounted on the vehicle body, and the slit hole is provided between the claw portion and the protrusion portion in the width direction of the passenger seat.

[0026] In the above configuration, since the claw portion and the convex portion are located on opposite sides of each other with the slit hole as the boundary, when the free end portion of the extension portion is hooked on the claw portion, interference with the convex portion can be avoided, and at the same time, the extension portion can be hooked on the claw portion more simply.

[0027] In the seat for a vehicle according to the present invention, the joint portion of the skin piece is appropriately stretched, and as a result, the side support portion can have a good appearance.

[0028] In addition, in the seat for a vehicle according to the present invention, compared with the configuration in which the belt body as the extension portion is hooked on the outer edge portion of the base member, the length of the belt body is shorter.

[0029] In addition, in the seat for a vehicle according to the present invention, since the extension portion and the sewing of the plurality of skin pieces are carried out together, the installation of the extension portion can be effectively performed.

[0030] In addition, in the seat for a vehicle according to the present invention, a reduction in the strength of the base member accompanying the formation of the slit hole can be suppressed, and the belt body can pass through the slit hole appropriately.

[0031] In addition, in the seat for a vehicle according to the present invention, the belt body can pass through the slit hole simply, and at the same time, the length of the belt body is shorter.

[0032] In addition, in the seat for a vehicle according to the present invention, the extension portion is stabilized in the stretched state, and the state in which the joint portion of the skin pieces in the skin is stretched can be appropriately maintained. As a result, the appearance of the side support portion can be made better.

[0033] In addition, in the seat for a vehicle according to the present invention, by accommodating the joint portion of the skin pieces in the groove portion, the thicker portion of the skin is made less conspicuous.

[0034] In addition, in the seat for a vehicle according to the present invention, since the base portion of the extension portion and the free end portion of the extension portion are located on the same side in the width direction of the seat for a vehicle, the length of the extension portion is shorter.

[0035] In addition, in the seat for a vehicle according to the present invention, the free end portion of the extension portion can be fixed to the base member with a simpler configuration.

[0036] In addition, in the seat for a vehicle according to the present invention, when the free end portion of the extension portion is hooked on the claw portion, interference with the convex portion can be avoided, and at the same time, the extension portion can be hooked on the claw portion more simply.

[0051] The following describes a configuration example of a passenger seat according to one embodiment of the present invention (this embodiment). In this embodiment, a vehicle seat (hereinafter referred to as seat S) is used as an example of a passenger seat. However, the present invention is also applicable to passenger seats other than vehicles, such as those installed in ships and aircraft.

[0052] In addition, in the following description, the "front-rear direction" corresponds to the front-rear direction of the seat S and is the direction consistent with the traveling direction of the vehicle on which the seat S is mounted. In addition, the "seat width direction" is the width direction (lateral width direction) of the seat S and is the left-right direction of the seat S when viewed from the front. In addition, the "up-down direction" is the up-down direction of the seat backrest 1 of the seat S and is the direction consistent with the up-down direction of the side support portion 4 that constitutes the side end portion of the seat backrest 1.

[0053] In addition, the "outer side" in the seat width direction corresponds to one end side in the seat width direction. Specifically, it represents the side closer to the vehicle door. In addition, the "inner side" in the seat width direction corresponds to the other end side in the seat width direction and represents the side closer to the center in the left-right direction of the vehicle.

[0054] In addition, when the positions of the respective parts of the seat S are described below, unless otherwise specified, the description is based on the seated person (a passenger in the vehicle) seated on the seat S.

[0055] The basic configuration of the seat S.

[0056] As Figure 1 shown, the seat S is used as a rear seat of the vehicle and has a seat backrest 1 and a seat cushion 2. Figure 1 is a perspective view of the seat S. The seat backrest 1 is the part that supports the upper body of the seated person, and the seat cushion 2 is the part where the passenger's buttocks and thighs are placed. In addition, Figure 1 the seat S shown is a two-seater seat, but it is not limited thereto, and it may also be a single-seater seat or a seat that can accommodate three or more people.

[0057] As Figure 1 shown, the seat backrest 1 has a back support portion 3 and a side support portion 4. The back support portion 3 is the main part of the seat backrest 1, is provided at the center in the seat width direction of the seat backrest 1, and supports the back of the seated person from behind. The side support portion 4 is located on the side of the back support portion 3. Specifically, it is disposed between the back support portion 3 and the vehicle door (not shown) in the seat width direction. The front surface of the side support portion 4 is located beside the seated person and supports the part from the shoulder to the waist of the seated person from the side. In addition, as Figure 1 shown, the front surface of the side support portion 4 is located more forward than the front surface of the back support portion 3. Further, the front surface of the side support portion 4 is inclined so as to be more forward toward the outer side in the seat width direction.

[0058] The side supports 4 are fixed to the vehicle body. Specifically, fastening portions (not shown) are provided in the vehicle body further rearward than the side supports 4, and the side supports 4 are fastened by these fastening portions. Furthermore, the lower ends of the side supports 4 (strictly speaking, the lower ends of the base member 10) are fixed to the vehicle body floor with bolts.

[0059] The structure of the side support portion 4.

[0060] As for the side support portion 4, Figure 2 As shown, the side support portion 4 is formed by covering the base member 10 constituting its frame from the front with the skin 30. The side support portion 4 formed in this way presents Figure 3 The exterior shown, as shown in the figure, extends sufficiently long in the up-down direction and is relatively wide in the seat width direction.

[0061] also, Figure 2 4 is a diagram showing the components of the side support portion 4. Figure 3 This is an appearance diagram of the side support portion 4.

[0062] The base member 10 is a member for defining the outer shape of the side support portion 4 and is formed of a resin molded article in this embodiment. However, the base member 10 may also be formed of a metal member, more specifically, may be formed by processing a metal plate.

[0063] The base member 10 is formed into a substantially plate-like shape, and is formed into a quadrilateral like a knife tip when viewed from the front. In addition, the front face of the base member 10 is substantially flat. The structure of the base member 10 will be described in detail later.

[0064] In the following description, in the thickness direction of the base member 10 , the side closer to the body of the occupant when the occupant is seated on the seat S is referred to as the “front side,” and the side farther from the body of the occupant is referred to as the “back side.”

[0065] like Figure 4 As shown, the skin 30 is a member that covers the surface side of the base member 10 and constitutes the outer surface of the side support portion 4. Figure 4 The cross section of the side support portion 4 is shown, specifically Figure 3 Figure 2 shows the HH cross section of the PDMS detector.

[0066] The cover 30 is made of fabric (cloth), natural leather or artificial leather or a laminate of these materials. The cover 30 has a slight thickness and gives a soft touch when the body of the seated person contacts its surface.

[0067] In addition, in the following description, in the thickness direction of the skin 30, when the seated person is seated on the seat S, the side closer to the seated person's body (in other words, the exposed side) is referred to as the "front side", and the side farther from the seated person's body (in other words, the side opposite to the base member 10) is referred to as the "back side".

[0068] In the present embodiment, the skin 30 is constituted by joining a plurality of skin pieces to each other. More specifically, the skin 30 is constituted by sewing the skin pieces divided into two in the seat width direction. That is, as Figure 4 shown, a portion where the skin pieces are joined (hereinafter referred to as the joining portion 40) is formed at the center in the seat width direction of the skin 30. At the joining portion 40, the end portions in the seat width direction of the respective skin pieces are folded back toward the back side, and the respective end portions of the folded-back skin pieces are joined by sewing.

[0069] In addition, in the following description, of the two skin pieces constituting the skin 30, the one located on the outer side (one end portion) in the seat width direction is referred to as the outer skin piece 33, and the one located on the inner side (the other end side) is referred to as the inner skin piece 34. Here, the outer skin piece 33 corresponds to the first skin piece, and the inner skin piece 34 corresponds to the second skin piece.

[0070] In addition, in the present embodiment, the skin 30 is constituted by joining two skin pieces to each other, but it is not limited thereto, and the skin 30 may be constituted by joining three or more skin pieces to each other.

[0071] The skin 30 is fixed to the base member 10 in a state of covering the base member 10. More specifically, as Figure 4 shown, the end portion on the outer side in the seat width direction of the skin 30 (hereinafter referred to as the outer end portion 31) is hung on the portion on the outer side in the seat width direction of the base member 10 (hereinafter referred to as the outer base portion 11).

[0072] In addition, the outer end portion 31 is constituted by the end portion on the outer side in the seat width direction of the outer skin piece 33. And, as Figure 4 shown, the outer end portion 31 is bent along the portion on the outer side of the outer edge of the base member 10 in the seat width direction, and is wound from the front side of the base member 10 to the back side.

[0073] As Figure 4 shown, the end portion on the inner side in the seat width direction of the skin 30 (hereinafter referred to as the inner end portion 32) is hung on the portion on the inner side in the seat width direction of the base member 10 (hereinafter referred to as the inner base portion 12), and is fitted into the fitting groove 26 provided in the inner base portion 12.

[0074] In addition, the inner end portion 32 is constituted by the end portion on the inner side in the seat width direction of the inner skin piece 34. And, as Figure 4 As shown, the inner end portion 32 is bent along the portion of the outer edge of the base member 10 that is located inside the seat width direction.

[0075] In the skin 30, the joint portion 40 is pulled and suspended on the inner side of the base member 10 (in other words, on the opposite side of the side where the joint portion 40 is located with respect to the base member 10).

[0076] The structure of the skin 30 for fixing the skin 30 to the base member 10.

[0077] Hereinafter, with reference to Figure 4 and Figure 5 The structure of the skin 30 for fixing each part of the skin 30 (specifically, the outer end portion 31, the inner end portion 32, and the joint portion 40) to the base member 10 will be described. Figure 5 This is a view showing the inner side of the skin 30.

[0078] In the outer end portion 31 of the skin 30, holes (hereinafter referred to as locking holes 36) having a cutout shape for inserting a protrusion (strictly speaking, a claw portion 16 described later) protruding from the inner side of the outer base portion 11 of the base member 10 are formed. As Figure 5 shown, a plurality of these locking holes 36 are provided at intervals in the vertical direction between the locking holes 36.

[0079] Similarly, locking holes 36 are provided in the inner end portion 32 of the skin 30. As Figure 5 shown, in the inner end portion 32, two locking holes 36 are provided at positions spaced apart in the vertical direction. Further, as Figure 5 shown, in the inner end portion 32, a decorative cord 37 extending in the vertical direction is attached to the portion between the locking holes 36 in the vertical direction. This decorative cord 37 is a fitting portion that enters a fitting groove 26 provided in the inner base portion 12 of the base member 10.

[0080] A belt body 35 as an extension portion is attached to the joint portion 40 of the skin 30. This belt body 35 is a long strip-shaped belt body that extends from the joint portion 40 in the inner side portion of the skin 30. When the skin 30 is fixed to the base member 10, the belt body 35 is pulled and suspended on the inner side of the base member 10 (in other words, on the opposite side of the side where the joint portion 40 is located with respect to the base member 10).

[0081] Further, in a state where the belt body 35 is stretched, the free end portion 35b of the belt body 35 is hung on a protrusion (strictly speaking, a claw portion 16 described later) protruding from the inside of the outer base portion 11 of the base member 10. Further, the free end portion 35b is the end portion of the belt body 35 on the side opposite to the base portion 35a mounted on the joint portion 40, and is a short side portion of the belt body 35 having a rectangular shape. Further, a hole (hereinafter, a suspension hole 35c) for inserting the protrusion of the base member 10 is formed in the free end portion 35b.

[0082] As Figure 5 shown, a plurality of belt bodies 35 ( Figure 5 five in the illustrated case) are provided at intervals between the belt bodies 35 along the joint portion 40. Further, the belt body 35 of the present embodiment is made of a material having lower extensibility than the skin pieces (that is, the outer skin piece 33 and the inner skin piece 34) constituting the skin 30, and is made of, for example, a nylon belt or the like.

[0083] Further, in the present embodiment, each belt body 35 is sewn to each skin piece (that is, the outer skin piece 33 and the inner skin piece 34) at the joint portion 40. Specifically, the base portion 35a of each belt body 35 is sewn to each skin piece. Further, as Figure 4 shown, the base portion 35a is mounted on the joint portion 40 in a state of being in contact with the outer skin piece 33.

[0084] Regarding the structure of the base member 10.

[0085] Refer to Figure 4 and Figures 6 to 12 to describe the structure of the base member 10. Figure 6 FIG. is a view of the base member 10 as seen from the front side. Figure 7 FIG. is a view of the base member 10 as seen from the back side. Figure 8 FIG. is a view of the back side portion of the base member 10 as seen from obliquely below. Fig. 9 FIG. is an enlarged view showing the upper portion of the back side portion of the base member 10. Fig.10 As Figure 6 shown, FIG. is a sectional view taken along line I-I. Fig.11 As Figure 6 shown, FIG. is a sectional view taken along line J-J.

[0086] As described above, the base member 10 is a resin molded product and has the Figure 6 and Figure 7 appearance shown in the figure. An installation portion 28 extending downward in a tongue shape is provided at the lower end portion of the base member 10. A bolt hole is provided at the top portion (lower end portion) of the installation portion 28, and the installation portion 28 is fixed to the vehicle body floor by a fastening bolt (not shown) inserted into the bolt hole.

[0087] The base member 10 is roughly divided into two parts in the seat width direction. Specifically, it has an outer base part 11 located on the outer side in the seat width direction and an inner base part 12 located on the inner side in the seat width direction. The outer base part 11 is the part closer to the outer skin piece 33 among the outer skin piece 33 and the inner skin piece 34 that constitute the skin 30 when the skin 30 is fixed to the base member 10. The inner base part 12 is the part closer to the inner skin piece 34 of the skin 30 when the skin 30 is fixed to the base member 10.

[0088] In addition, as Figure 6 shown, a storage groove part 13 formed by being recessed backward is provided on the surface of the base member 10. This storage groove part 13 is a groove part formed from the upper end to the lower end of the base member 10. And, as Figure 4 shown, in the state where the skin 30 covers and is fixed to the base member 10, the joint part 40 of the skin 30 enters the storage groove part 13 and is thus stored. That is, when the joint part 40 is suspended with respect to the base member 10, the joint part 40 enters the storage groove part 13.

[0089] Furthermore, in the base member 10, the storage groove part 13 constitutes the boundary between the outer base part 11 and the inner base part 12. The outer base part 11 is located on the outer side in the seat width direction than the storage groove part 13, and the inner base part 12 is located on the inner side in the seat width direction than the storage groove part 13. In addition, as Figure 6 shown, on the surface of the inner base part 12, at a position beside the storage groove part 13, a plurality of short rectangular holes (hereinafter referred to as a rectangular hole group 14) arranged in the vertical direction are provided. Each rectangular hole in the rectangular hole group 14 is formed for taking out the base member 10 from the mold when the base member 10 is resin molded. In addition, in the inner base part 12, the part located between the rectangular hole group 14 and the storage groove part 13 in the seat width direction, as Fig.11 shown, forms a wall thickness part 15 that is thicker than the thickness of its periphery.

[0090] As Figure 8 and Fig. 9 shown, a claw part 16 protruding backward is provided on the back surface of the base member 10. This claw part 16 is the part that hooks the outer end 31 or the inner end 32 of the skin 30 when the skin 30 is fixed to the base member 10. By hanging the outer end 31 or the inner end 32 on the claw part 16, the skin 30 covering the base member 10 is stretched.

[0091] In addition, in the present embodiment, a plurality of claw portions 16 are provided inside the base member 10. More specifically, a plurality of claw portions 16 are provided in the vertical direction inside each of the outer base portion 11 and the inner base portion 12. Hereinafter, the details of the claw portion 16 will be described.

[0092] A plurality of claw portions 16 (hereinafter referred to as first claw portions 16A) provided inside the outer base portion 11 are located at the outer end portion of the outer base portion 11 in the seat width direction and are arranged along the storage groove portion 13. In addition, in Figure 8 the case shown, six first claw portions 16A are arranged side by side at intervals. As Fig. 9 shown, the tip portions of the respective first claw portions 16A are formed so as to extend from the outer end portion of the base member 10 toward the inner end portion in the seat width direction.

[0093] Referring to Fig. 9 to describe the configuration of the first claw portion 16A, the claw portion 16 has a core portion 17 that constitutes its main body portion. As Fig. 9 shown, the core portion 17 has a rear protruding portion 17a that extends rearward from the inside of the base member 10 and a tip protruding portion 17b that is adjacent to the tip of the rear protruding portion 17a. As described above, the tip protruding portion 17b of the first claw portion 16A extends from the outer end portion of the base member 10 toward the inner end portion in the seat width direction (in other words, the direction that intersects the protruding direction of the rear protruding portion 17a). That is, the tip protruding portion 17b of the first claw portion 16A protrudes toward the central position of the base member 10 in the seat width direction.

[0094] In addition, in the present embodiment, as Fig. 9 shown, in the seat width direction, the first claw portion 16A is arranged between the portion of the base member 10 that faces the outer end portion 31 of the skin 30 and the aforementioned storage groove portion 13. Here, the portion that faces the outer end portion 31 is the portion of the inside of the base member 10 where the outer end portion 31 faces the outer end portion 31 by being folded back along the outer edge of the base member 10 (strictly speaking, the outer end portion in the seat width direction of the outer edge).

[0095] In addition, vertical direction extending portions 18 that extend in the vertical direction are provided on each of the upper and lower end faces of the core portion 17. The vertical direction extending portions 18 are provided to strengthen the core portion 17 of the first claw portion 16A. In addition, as Fig. 9 shown, the vertical direction extending portions 18 are bent in an L shape, and the portion corresponding to one side extends from the rear protruding portion 17a, and the portion corresponding to the other side extends from the tip protruding portion 17b.

[0096] In addition, an adjacent protrusion 19 is provided at the base of the rear protrusion 17a of the core 17. The adjacent protrusion 19 is provided to reinforce the first claw 16A and protrudes rearward at a position adjacent to the first claw 16A. Fig. 9 As shown, the abutment protrusion 19 extends in the seat width direction toward the outer edge of the base member 10 (strictly speaking, the outer end portion in the seat width direction of the outer edge).

[0097] like Figure 8 As shown, multiple claws 16 (hereinafter referred to as second claws 16B) provided on the inner surface of the inner base portion 12 are arranged at positions spaced apart from each other in the vertical direction. The second claws 16B have the same basic structure as the first claws 16A, and include a core 17 and vertically extending portions 18 extending from the core 17. Furthermore, adjacent protrusions 19 protrude rearwardly from the positions adjacent to the core 17 of the second claws 16B.

[0098] like Figure 8 As shown, the tip end portion of the second claw portion 16B (strictly speaking, the tip protruding portion 17b of the core portion 17) is formed so as to extend from the inner end portion to the outer end portion of the base member 10 in the seat width direction. In other words, the tip protruding portion 17b of the second claw portion 16B, like the tip protruding portion 17b of the first claw portion 16A, protrudes toward the center of the base member 10 in the seat width direction.

[0099] Returning to the description of the structure of the base member 10, a plurality of protrusions for attaching the side support portion 4 to the vehicle body are formed on the inner surface of the base member 10. Specifically, the first fastening portion 21, the second fastening portion 22, the first abutting portion 23, and the second abutting portion 24 each protrude rearward from the inner surface of the base member 10.

[0100] The first fastening portion 21 is a socket-like protrusion provided at the upper end of the inner base portion 12 of the base member 10. It is inserted into an insertion portion (not shown) mounted on the vehicle body and is configured to engage with the insertion portion. In other words, the first fastening portion 21 engages with a portion of the vehicle body when the side support portion 4 is mounted on the vehicle body.

[0101] The second fastening portion 22, equivalent to a convex portion, is a latch-like protrusion provided on the inner base portion 12 slightly below the first fastening portion 21. It is inserted into a receiving portion (not shown) mounted on the vehicle body and is configured to engage with the receiving portion. In other words, the second fastening portion 22 engages with a portion of the vehicle body when the side support portion 4 is mounted on the vehicle body.

[0102] In addition, if Fig. 9As shown, the second fastening portion 22 protrudes rearward more than the first claw portion 16A and also more than the second claw portion 16B.

[0103] The first and second abutment portions 23, 24 correspond to convex portions and are generally semicircular, cylindrical bodies. The first abutment portion 23 is located below the second fastening portion 22 within the inner base portion 12, adjacent to the receiving groove 13. The second abutment portion 24 is located at the lower end of the inner base portion 12, adjacent to the receiving groove 13. When the side support 4 is mounted on the vehicle body, the first and second abutment portions 23, 24 respectively abut against a portion of the vehicle body to position the side support 4.

[0104] In addition, if Fig. 9 As shown, the first contact portion 23 protrudes rearwardly more than the first claw 16A and also more than the second claw 16B. Similarly, the second contact portion 24 protrudes rearwardly more than the first claw 16A and the second claw 16B.

[0105] In addition, in this embodiment, if Figure 7 As shown, the second fastening portion 22, the first abutting portion 23 and the second abutting portion 24 are arranged between the first claw portion 16A and the second claw portion 16B in the seat width direction. Strictly speaking, they are arranged between the first claw portion 16A located at the outermost side and the second claw portion 16B located at the innermost side in the seat width direction.

[0106] like Figure 6 、 Figure 7 、 Figure 8 As shown, a rectangular slit 25 is formed in the receiving groove 13 of the base member 10. This slit 25 extends through the bottom 13a of the receiving groove 13 and is a hole through which the belt 35 is passed when the cover 30 covers the base member 10 and hangs the joint 40. In other words, the belt 35 passes through the slit 25 and is pulled toward the inner side of the base member 10 and hung there.

[0107] In this embodiment, a plurality of slits 25 are provided at intervals along the receiving groove 13. More specifically, the same number of slits 25 as the number of straps 35 (i.e., five) is provided. That is, in this embodiment, a slit 25 is provided in the base member 10 for each strap 35, and each strap 35 passes through a corresponding slit 25 among the plurality of slits 25.

[0108] In addition, if Figure 4As shown in FIG. 1 , each slit hole 25 is formed so that its rear end opening 25 a faces outward (door side) in the seat width direction. Therefore, when the belt 35 is passed through the slit hole 25, the free end 35 b of the belt 35 faces outward in the seat width direction.

[0109] like Figure 7 As shown, in this embodiment, each slit hole 25 is arranged between the first claw portion 16A (strictly speaking, the first claw portion 16A located outermost in the seat width direction) and the above-mentioned protrusion (specifically, the second fastening portion 22) in the seat width direction.

[0110] like Figure 7 and Figure 8 As shown, the base member 10 has an engagement groove 26 at the inner end in the seat width direction. The engagement groove 26 is a groove into which the decorative cord 37 attached to the inner end 32 of the skin 30 enters (fits) when the skin 30 is fixed to the base member 10.

[0111] The fitting groove 26 is provided in the inner base portion 12 of the base member 10. Figure 4 As shown, the inner end portion of the inner base portion 12 in the seat width direction is curved into an L-shape extending rearward. Furthermore, a fitting groove 26 is formed on the rear end surface (i.e., the inner surface) of the inner end portion of the inner base portion 12, extending elongated in the vertical direction. The inner end portion of the inner base portion 12 in the seat width direction where the fitting groove 26 is provided corresponds to the end of the base member 10 that is closer to the second claw portion 16B than the first claw portion 16A in the seat width direction.

[0112] In addition, if Figure 7 and Figure 8 As shown, the fitting groove 26 is arranged between two second claws 16B provided at positions spaced apart from each other in the up-down direction.

[0113] Furthermore, a portion of the inner wall surface of the fitting groove 26 is formed Fig.10 The fixing flange 27 is formed by protruding in the manner shown. By forming the fixing flange 27, the decorative cord 37 fitted into the fitting groove 26 can be prevented from falling out of the fitting groove 26.

[0114] Regarding the method of fixing the skin 30 to the base member 10 .

[0115] Next, refer to Figure 4 、 Fig.12 and Fig.13 A method of fixing the skin 30 to the base member 10 will be described. Fig.12 This is an explanatory diagram regarding the structure for stretching the skin 30 covering the base member 10 . Fig.13 This is a side view of the belt body 35 and the outer end portion 31 of the cover 30 hung on the first claw 16A.

[0116] When the skin 30 is fixed to the base member 10, the skin 30 is brought closer to the base member 10 from the front of the base member 10, and the skin 30 covers the surface (front side surface) of the base member 10. Figure 4 As shown, the joint portion 40 of the skin 30 enters the receiving groove 13 .

[0117] More specifically, the plurality of straps 35 sewn to the joint portion 40 are each passed through the slits 25 formed in the bottom portion 13a of the storage groove 13 and pulled toward the back side of the base member 10. Specifically, in this embodiment, when the cover 30 is secured to the base member 10, the cover 30 covers the base member 10, and in this state, the straps 35 are passed through the slits 25 and pulled toward the back side of the base member 10 (in other words, the side of the base member 10 opposite to the side where the joint portion 40 is located).

[0118] In addition, if Figure 4 As shown, in a state where the cover 30 covers the base member 10 , the base portion 35 a of the belt body 35 is housed (arranged) in the housing groove 13 together with the joint portion 40 .

[0119] In addition, if Figure 4 As shown, the opening 25a of the slit hole 25 (strictly speaking, the opening 25a located on the back side of the base member 10) faces outward in the seat width direction. In addition, the free end 35b of the belt body 35 extends outward from the slit hole 25 through the opening 25a.

[0120] In this embodiment, a plurality of belts 35 are attached to the joint portion 40 , and the base member 10 is provided with the same number of slits 25 as the number of belts 35 . The corresponding belts 35 are passed through the slits 25 .

[0121] In addition, when the cover 30 covers the base member 10, the portion where the belt 35 is attached to the back side of the cover 30 and the portion where the slit hole 25 is provided in the base member 10 are arranged in a manner that overlaps with each other. Figure 4 As shown, when the cover 30 covers the base member 10, the base portion 35a of the belt 35 attached to the joint portion 40 is positioned adjacent to the slit hole 25 through which the belt 35 passes. With this positional relationship, the length of each belt 35 required to pass through the slit hole 25 can be further shortened.

[0122] After the free end portion 35b of the belt body 35 passes through the opening 25a of the slit hole 25 and extends out of the slit hole 25, as shown in FIG. Figure 4 As shown, the belt body 35 is kept in a state of being pulled toward the inner side (i.e., the rear) of the base member 10, and is bent into an L-shape at an intermediate position (specifically, the portion of the bottom 13a of the storage groove portion 13 that faces the outer edge of the opening 25a). Accordingly, the free end portion 35b of the belt body 35 faces the outer side in the seat width direction.

[0123] On the other hand, a first claw portion 16A is provided on the inner side of the outer base portion 11 located on the outer side in the seat width direction in the base member 10. And as Figure 4 and Fig.12 shown, the free end portion 35b of the belt body 35 is hooked on the top protruding portion 17b of the first claw portion 16A on the inner side of the base member 10. Specifically, by inserting the core portion 17 and the vertically extending portion 18 of the first claw portion 16A into the hanging hole 35c formed in the free end portion 35a, the free end portion 35b of the belt body 35 is engaged with the first claw portion 16A.

[0124] In addition, the first claw portion 16A is provided at the end portion (one end portion of the base member 10) on the outer side in the seat width direction in the inner side of the outer base portion 11. That is to say, in the present embodiment, the free end portion 35b of the belt body 35 is hooked on the end portion on the outer side in the seat width direction of the outer base portion 11.

[0125] Furthermore, the opening 25a of the slit hole 25 through which the base portion 35a of the belt body 35 passes faces the outer side in the seat width direction, that is, the side where the first claw portion 16A is located. According to such a configuration, the base portion 35a of the belt body 35 can be fixed to the first claw portion 16A more simply.

[0126] And after all the belt bodies 35 are engaged with the first claw portion 16A, the joint portion 40 to which the base portion 35a of the belt body 35 is attached enters the storage groove portion 13 together with the base portion 35a of the belt body 35 and is suspended.

[0127] After the suspension of the joint portion 40 is completed, the outer end portion 31 of the skin 30 is fixed to the end portion on the outer side in the seat width direction of the outer base portion 11. More specifically, by bending the outer end portion 31 of the skin 30 along the portion of the outer edge of the outer base portion 11 that is located on the outer side in the seat width direction, the outer end portion 31 is wound from the surface side of the outer base portion 11 to the inner side. And as Fig.12As shown, the outer end portion 31 that turns toward the inner side of the outer base portion 11 is hooked on the first claw portion 16A. Specifically, in the outer end portion 31, a plurality of locking holes 36 formed at intervals in the vertical direction are inserted into the core portion 17 and the vertically extending portion 18 of the first claw portion 16A. Accordingly, the portion of the outer end portion 31 of the skin 30 that turns toward the inner side of the outer base portion 11 is hooked on the first claw portion 16A and fixed to the outer end portion in the seat width direction of the outer base portion 11.

[0128] In addition, in the present embodiment, the same number of locking holes 36 as the first claw portion 16A are formed in the outer end portion 31 of the skin 30. The corresponding first claw portions 16A are respectively inserted into the respective locking holes 36.

[0129] As described above, the belt body 35 mounted on the joint portion 40 and the outer end portion 31 of the skin 30 that turns toward the inner side of the base member 10 are hooked on the first claw portion 16A. As Fig.13 shown, the outer end portion 31 of the skin 30 is hooked on the portion of the first claw portion 16A that is closer to the tip of the first claw portion 16A (strictly speaking, the protruding portion 17b at the tip of the core portion 17) than the portion where the belt body 35 is hooked.

[0130] In a state where both the belt body 35 and the outer end portion 31 are hooked on the first claw portion 16A, the belt body 35 and the outer end portion 31 respectively apply forces in opposite directions to the first claw portion 16A. Specifically, as Figure 4 shown, in the seat width direction, among the outer edges of the base member 10, the first claw portion 16A is disposed between the portion where the outer end portion 31 of the skin 30 turns back and the slit hole 35 through which the belt body 35 passes.

[0131] Due to the above positional relationship, the belt body 35 approaches the first claw portion 16A from a position closer to the inner side in the seat width direction than the first claw portion 16A and is hooked on the first claw portion 16A. As a result, the belt body 35 applies a Fig.13 tensile load in the direction indicated by the arrow f1 in Fig.13 . On the other hand, the outer end portion 31 of the skin 30 approaches the first claw portion 16A from a position closer to the outer side in the seat width direction than the first claw portion 16A and is hooked on the first claw portion 16A. As a result, the outer end portion 31 applies a

[0132] tensile load in the direction indicated by the arrow f2 in

[0133] . Here, the above two tensile loads are forces in opposite directions. Accordingly, it is possible to prevent the tensile load acting on the first claw portion 16A from being excessively concentrated in one direction.

[0132] As described above, the outer end portion 31 of the skin 30 is fixed to the outer end portion in the seat width direction of the outer base portion 11.

[0133] On the other hand, the inner end portion 32 of the skin 30 is fixed to the inner end portion in the seat width direction of the inner base portion 12 of the base member 10. More specifically, the inner end portion 32 of the skin 30 is bent along the portion of the outer edge of the inner base portion 12 that is located on the inner side in the seat width direction. Further, a specific portion of the inner end portion 32 (specifically, the portion where the locking hole 36 is formed) is wound from the surface side of the inner base portion 12 to the inner side.

[0134] As described above, on the inner side of the inner base portion 12, two second claw portions 16B are provided at positions spaced apart vertically. And, as Figure 4 shown, the inner end portions 32 wound to the inner side of the inner base portion 12 are respectively hung on the two second claw portions 16B above and below. More specifically, the two locking holes 36 provided at positions separated vertically in the inner end portion 32 are respectively inserted into the core portion 17 and the vertically extending portion 18 of the corresponding second claw portion 16B. Accordingly, in the inner end portion 32 of the skin 30, the portion wound to the inner side of the inner base portion 12 is hung on the second claw portion 16B.

[0135] Further, in the inner end portion 32, a decorative cord 37 is installed at a portion located between the two second claw portions 16B above and below in the vertical direction. This decorative cord 37 enters (is embedded in) the fitting groove 26 formed at the inner end portion in the seat width direction on the inner side of the inner base portion 12. Thus, in the present embodiment, the inner end portion 32 of the skin 30 is hung on the two second claw portions 16B above and below, and at the same time, is embedded in the fitting groove 26 between the second claw portions 16B in the vertical direction.

[0136] Through the steps described above, each part of the skin 30 (specifically, the outer end portion 31, the inner end portion 32, and the joint portion 40) is fixed to the base member 10. And, by fixing the skin 30 to the base member 10, the side support portion 4 according to the present embodiment is constituted.

[0137] Other embodiments.

[0138] One specific embodiment of the seat for a vehicle according to the present invention has been described above. However, the above-described embodiment is merely an example for making the present invention easy to understand, and does not limit the present invention. That is, without departing from the gist of the present invention, it is obvious that the present invention includes its equivalents while being changed and improved.

[0139] In addition, regarding the configuration of each part of the seat S, it is merely an example, and as long as the effects of the present invention can be achieved (for example, achieving a good appearance of the side support portion 4), shapes different from the above-described embodiment can be used. For example, in the above-described embodiment, the side support portion 4 is constituted by directly covering the base member 10 with the skin 30. That is, as Figure 6As shown, in the above-described embodiment, the surface (front side) of the base member 10 is a flat surface, and the skin 30 is disposed directly in front thereof, but it is not limited thereto. As Fig.14 shown, a base member 100 having a fitting recess 101 in which a gasket material (not shown) is embedded on its surface may also be used, and the base member 100 in a state where the gasket member is fitted into the fitting recess 101 covers the skin 30 to constitute the lateral support portion 4. Fig.14 FIG. is a perspective view showing the base member 100 according to the modification.

[0140] In addition, in a state where the gasket member is fitted into the fitting recess 101, the base member 100 according to the modification is formed to have substantially the same structure as the Figure 6 base member 10 shown in the above-described embodiment. Further, in Fig.14 , the same portions of the base member 100 according to the modification as those of the base member 10 according to the above-described embodiment are denoted by the same reference numerals (i.e., the same reference numerals as Figure 6 those shown).

[0141] In addition, the vehicle seat according to the present embodiment includes a back support portion that supports the back of a seated person, and a lateral support portion that is located on the side of the back support portion. The lateral support portion includes a base member that defines an outer shape of the lateral support portion, and a skin that covers the base member and constitutes an outer surface of the lateral support portion. The skin includes a plurality of skin pieces that are joined to each other to form the skin. A groove portion into which a portion where the skin pieces are joined enters is provided on the surface of the base member, and a plurality of claw portions on which ends of the skin are hooked are provided along the groove portion inside the base member in order to stretch the skin.

[0142] Regarding the skin that constitutes the lateral support portion, the skin is sometimes formed by joining a plurality of skin pieces. In such a configuration, when covering the base member with the skin, it is necessary to stretch a portion where the skin pieces are joined in the skin to stretch the skin. At this time, if the skin is not properly stretched, the appearance of the lateral support portion may be affected.

[0143] In contrast, in the vehicle seat configured as described above, a portion where the skin pieces are joined in the skin enters a groove portion provided on the surface of the base member, and ends of the skin are hooked on respective claw portions provided inside the base member, so that the skin is stretched. In this configuration, since the ends of the skin are hooked on the plurality of claw portions, it is possible to prevent a portion where the skin pieces are joined in the skin from being overstretched. Accordingly, the portion where the skin pieces are joined is properly stretched, and as a result, the lateral support portion has a good appearance.

[0144] That is, according to the above-described vehicle seat, the skin can be properly stretched in the lateral support portion.

[0145] In addition, in the above-described seat for a vehicle, the claw portion has a rear protruding portion that protrudes rearward, and a tip protruding portion that is adjacent to the tip of the rear protruding portion and protrudes in a direction crossing the protruding direction of the rear protruding portion.

[0146] With the above-described configuration, it is possible to suppress the end portion of the skin caught on the claw portion from coming off the claw portion with a simpler configuration.

[0147] In addition, in the above-described seat for a vehicle, it is preferable that the tip protruding portion protrudes toward the central position of the base member in the width direction of the seat for a vehicle.

[0148] In the above-described configuration, on the one hand, the end portion of the skin is pulled toward the central position of the base member in the width direction of the seat for a vehicle and caught on the claw portion, and on the other hand, the tip protruding portion of the claw portion protrudes toward the central position of the base member. With this configuration, it is possible to effectively suppress the end portion of the skin caught on the claw portion from coming off the claw portion.

[0149] In addition, in the above-described seat for a vehicle, it is preferable that the skin has an extension portion that extends from a portion where the skin piece is joined on the inner side portion of the skin, and the extension portion is pulled toward the opposite side of the side where the skin piece is joined with respect to the base member and is caught on the claw portion, and the end portion of the skin is caught on a portion of the claw portion closer to the tip of the claw portion than the portion where the extension portion is caught.

[0150] In the above-described configuration, since the extension portion attached to the portion where the skin piece is joined on the skin and the end portion of the skin are caught on the claw portion together, a simpler configuration can be achieved compared to the case where portions for catching each component are provided separately.

[0151] In addition, in the above-described seat for a vehicle, it is preferable that a slit hole is provided in the base member, the extension portion passes through the slit hole and is pulled toward the opposite side of the side where the skin piece is joined with respect to the base member, and in the width direction of the seat for a vehicle, the claw portion is disposed between a portion where the end portion of the skin turns back on the outer edge of the base member and the slit hole.

[0152] In the above-described configuration, the end portion of the skin and the extension portion approach the claw portion from opposite sides in the width direction of the seat for a vehicle and are caught on the claw portion. With this configuration, it is possible to suppress an excessive force from acting on the claw portion on one side in the width direction of the seat for a vehicle.

[0153] In addition, in the above-described seat for a vehicle, it is preferable that the claw portion has a core portion of the claw portion and an up-and-down direction extension portion that extends in the up-and-down direction of the side support portion from the core portion.

[0154] In the above configuration, by providing an upward and downward extending portion on the claw portion, the rigidity of the claw portion can be improved.

[0155] In addition, in the above-described seat for a vehicle, it is preferable that an adjacent protruding portion that protrudes at a position adjacent to the claw portion is provided inside the base member, and the adjacent protruding portion extends along the width direction of the seat for a vehicle toward the outer edge of the base member.

[0156] In the above configuration, by providing an adjacent protruding portion around the claw portion in the base member, the rigidity around the claw portion in the base member can be improved.

[0157] In addition, in the above-described seat for a vehicle, it is preferable that a convex portion is provided inside the base member, the convex portion has a larger protruding amount than the claw portion, and engages or abuts against a part of the vehicle body in a state where the side support portion is mounted on the vehicle body.

[0158] In the above configuration, since the convex portion having a larger protruding amount than the claw portion engages or abuts against the vehicle body, damage caused by the claw portion coming into contact with the vehicle body can be suppressed.

[0159] In addition, in the above-described seat for a vehicle, it is preferable that the claw portion has a first claw portion whose tip extends from one end to the other end of the base member in the width direction of the seat for a vehicle, and a second claw portion whose tip extends from the other end to one end of the base member in the width direction, and the convex portion is disposed between the first claw portion and the second claw portion in the width direction.

[0160] In the above configuration, since the convex portion is provided between the first claw portion and the second claw portion in the width direction of the seat for a vehicle, damage caused by the first claw portion and the second claw portion coming into contact with the vehicle body respectively can be suppressed.

[0161] In addition, in the above-described seat for a vehicle, it is preferable that a plurality of the first claw portions and the second claw portions are respectively provided along the up and down direction of the side support portion, a fitting groove is formed at an end portion closer to the second claw portion than the first claw portion in the width direction in the base member, one end portion of the skin in the width direction is hooked on the plurality of first claw portions, the other end portion of the skin in the width direction is hooked on the plurality of second claw portions, and at the same time, the plurality of second claw portions enter the fitting groove in the up and down direction.

[0162] In the above configuration, one end of the cover in the width direction of the vehicle seat is hooked onto the plurality of first claws. Furthermore, the other end of the cover is hooked onto the plurality of second claws, and the cover is fitted into the fitting grooves of the base member between the plurality of second claws in the vertical direction of the side support portion. With this configuration, the vertical center portion of the cover, which is prone to wrinkling, can be appropriately stretched with a relatively simple structure, effectively suppressing the occurrence of wrinkles.
