Seat and skin fixing member

Abstract

The purpose of the present invention is to provide a seat and a skin fixing member capable of stably fixing a skin only using a fixing member. The skin fixing member (9) includes a skin attachment portion (12) and a locking portion (13). The engagement section (13) generates tension on the skin by sandwiching the engaged section between the outer engagement piece (17) and the inner engagement piece (18) and engaging the engaged section, and the inner protruding section (20) of the inner engagement piece (18) is pressed against the inner surface of the engaged section and becomes a fulcrum on the basis of the tension, and the outer protruding section (20) of the inner engagement piece (18) is pressed against the inner surface of the engaged section. A protruding portion (19) at the distal end of the outer locking piece (17) is pressed against the outer surface of the locked portion and receives a reaction force from the outer surface to serve as a force point, and the protruding portion (19) receives a reaction force in which both a rotational torque generated by tension of the skin and a rotational torque generated by a force acting on the skin attachment portion (12) are balanced.

Description

Technical Field

[0001] The invention relates to a seat with a skin covering the front surface of a base body and a skin fixing member. Background Art

[0002] Conventionally, there is known a seat mounted on a vehicle such as an automobile, which has a structure in which a cover covers the front surface of a base, and an end of the cover is locked to the base by a locking member.

[0003] For example, it is known that the rear seats in the three-row seat of the vehicle (e.g., see Figure 1 ) in the middle of the upper part of the elbow accommodating portion, when the end of the skin is clamped to the resin base using an end clamping member such as a clamp, use Fig.14 The fixing structure of the clamp 43 shown. In this fixing structure, on the base 41 above Z1 of the elbow rest accommodating portion 40 that accommodates the elbow rest AR, the end of the skin 42 covering the front surface side X1 of the base 41 is fastened to a specified point on the lower part of the base 41 using a clamp 43 (i.e., locked at the specified point). Therefore, the clamp 43 is easy to fall off due to the pulling force of the skin 42, and it is difficult to keep the tension of the skin 42 constant. In addition, since the hole for clamping the clamp is provided in the skin 42, a parting line is formed. Therefore, the appearance of the skin fixing structure is poor, and there is a high possibility that the locking member falls off.

[0004] In addition, as a locking member having a locking area larger than that of the clamping member, a fixing structure using a decorative cover (cover finisher) having a J-shaped cross-sectional shape capable of surface fixing is also known. In this fixing structure, the cover fixing member is fixed to the end of the skin, and the cover fixing member is locked in a notch formed on the base. However, this fixing structure requires a member for locking the cover fixing member in the notch of the base, and also requires a member for covering the notch. Therefore, this skin fixing structure also has a poor appearance, and the manufacturing cost is increased, and the convenience is poor.

[0005] In order to solve the above-mentioned problems (defective appearance and maintenance of locked state), a cover fixing structure capable of maintaining the locked state of the end of the cover without increasing the number of parts and without causing defective appearance is required.

[0006] In response to this requirement, for example, the following is known in Patent Document 1: Fig.15 The epidermal fixation structure shown. Fig.15 In the seat shown, a seat cushion 90 is mounted on a frame 71, and a skin 80 covers the surface of the seat cushion 90. The end of the skin 80 is fixed to the lower edge 71a of the frame 71 by a fixing member 50, and the space below the seat cushion 90 is covered by a cover member 60, so that the fixing position of the skin end is difficult to be seen from the outside.

[0007] Should Fig.15 The fixing member 50 shown is specifically a member having a Y-shaped cross section, and has an inner edge portion 51 arranged on the inner side of the frame 71, an outer edge portion 54 arranged on the outer side, and a lower protrusion 52 protruding downward. In the thin-walled portion 55 of the inner edge portion 51, the ends of the skin 80 are sewn together at the sewing portion 55a. The locking piece 53 provided on the inner edge portion 51 is locked to the lower edge portion 71a of the frame 71, and the lower edge portion 71a is clamped by the inner edge portion 51 and the outer edge portion 54, so that the fixing member 50 is locked to the lower edge portion 71a of the frame 71. The lower protrusion 52 is engaged with the upper end portion 61 of the cover member 60. Therefore, the fixing member 50 is engaged with the lower edge portion 71a of the frame 71 and the upper end portion 61 of the cover member 60, thereby maintaining the fixed state of the end of the skin 80.

[0008] but, Fig.15 When a strong pulling force A acts on the skin 80, the fixing member 50 rotates in the direction of the arrow B, and it is possible that the engagement between the locking piece 53 of the fixing member 50 and the lower edge 71a of the frame 71 is released, and the engagement between the lower protrusion 52 and the upper end 61 of the cover member 60 is also released. Fig.15 In the structure shown, there is still room for improvement in maintaining the locked state of the end of the skin.

[0029] Hereinafter, a seat and a cover fixing member according to an embodiment of the present invention will be described in detail with reference to the drawings.

[0030] (Overall structure of the seat)

[0031] As an example of an embodiment of the seat of the present invention, Figures 1-2 The seat 1 shown is a rear seat of a three-row seat of a vehicle. The seat 1 has main seats 2 on both sides and a center seat 3 in the middle. In the drawings used in this embodiment, the front-rear direction of the seat 1 is indicated by arrows X (front side X1, rear side (rear surface side) X2), the width direction is indicated by arrows Y, and the up-down direction is indicated by arrows Z (upper side Z1, lower side Z2).

[0032] like Figures 1 to 4 As shown, the central seat 3 includes a base 4 having an armrest accommodating portion 7, a headrest 5, an armrest 6, a skin 8 covering the upper portion of the base 4 (specifically, the upper side component 4b), and a skin fixing member 9 (hereinafter referred to as the fixing member 9) for fixing the skin 8 to the base 4.

[0033] like Figures 3-4 As shown, the armrest accommodation portion 7 is arranged on the outer side ( Figures 3-4 In a position adjacent to the lower side Z2). Figures 1-2 The armrest 6 shown is accommodated in the armrest accommodating portion 7 in an upright state and can support the back of the seated person. On the other hand, the armrest 6 can be taken out of the armrest accommodating portion 7 and laid down to the front side X1 to be used as an armrest for the seated persons of the main seats 2 on both sides.

[0034] like Figures 4-5 As shown in FIG. 1 , the base 4 includes a lower component 4a and an upper component 4b located at an upper side Z1 relative to the lower component 4a. The lower component 4a and the upper component 4b are integrally formed using resin to form a vertical rectangular base 4 that is a main body of the seat back that can support the back of the seated person. Figure 4 As shown, the base 4 is supported by a frame 10 , and the rear surface side X2 of the base 4 is covered by a backboard 11 and a skin 8 .

[0035] The lower component 4a is a vertical, generally plate-shaped portion that constitutes the bottom wall (the wall on the rear surface side X2) of the armrest accommodation portion 7. Figure 5 As shown, the lower component 4a of this embodiment includes a receiving portion 4a1 for receiving a distal end portion of a skin attachment portion 12 of a fixing member 9 described later, and an engaging portion 4a2 for engaging with the distal end portion.

[0036] like Figure 4 As shown, the upper component 4b protrudes toward the front side X1 relative to the lower component 4a at the upper side Z1 of the lower component 4a, and forms a step between the upper component 4b and the lower component 4a in the front-to-back direction X. By utilizing this step, the above-mentioned armrest accommodating portion 7 capable of accommodating the rectangular block-shaped armrest 6 is formed at the lower side Z2 of the upper component 4b and at the front side X1 of the lower component 4a.

[0037] A strip-shaped protrusion (reinforcement rib) 4d extending in the up-down direction Z is disposed on the front surface 4b2 of the upper component 4b. A plurality of strip-shaped protrusions 4d are arranged in a row in the width direction Y of the seat 1.

[0038] like Figures 4-5 As shown, a latched portion 4b1 is provided on the rear surface 4b3 of the upper component 4b. The latched portion 4b1 protrudes from an edge 4b31 of the lower side Z2 of the rear surface 4b3 of the upper component 4b toward the rear surface side X2. The latched portion 4b1 has an outer side ( Figure 5 The outer surface 4b11 of the lower side Z2) and the inner side ( Figure 5 The inner surface 4b12 of the upper side Z1) is formed. In addition, at the distal end portion (the end portion on the rear surface side X2) of the inner surface 4b12, an inclined surface 4b13 is formed that is inclined in the direction in which the locked portion 4b1 becomes thinner as it moves toward the distal end side (the rear surface side X2). A gap 4c is formed between the locked portion 4b1 and the lower component 4a. The fixing member 9 is embedded in the gap 4c.

[0039] like Figure 4 As shown, the skin 8 covers the front surface 4 b 2 of the upper side component 4 b of the base 4 , and covers the rear surface side X2 of the backboard 11 .

[0040] like Figure 5 As shown, the skin end 8a extends from the lower end (end on the lower side Z2) of the front surface 4b2 of the upper component 4b toward the rear surface side X2, and passes over the locked portion 4b1 toward the rear surface side X2 of the base.

[0041] (Structure of the fixing member 9)

[0042] The fixing member 9 is Figures 4-5The edge 4b31 of the rear surface 4b3 of the upper component 4b of the base 4 shown in the figure is configured so as to fix the skin end 8a to the locked portion 4b1 of the upper component 4b. Figures 5-6 As shown, the fixing member 9 includes: a skin mounting portion 12 to which the skin end portion 8a is mounted; a locking portion 13 locked to the locked portion 4b1; and a connecting arm portion 14 located between the skin mounting portion 12 and the locking portion 13 and connecting the two. The locking portion 13 is arranged on the side close to the locked portion 4b1 relative to the skin mounting portion 12 ( Figure 5 front side X1).

[0043] like Figure 6 As shown, the fixing member 9 of this embodiment is formed by a long strip-shaped member extending in the second direction D2, and the second direction D2 is perpendicular to the first direction D1 in which the skin mounting portion 12 and the locking portion 13 are arranged. Figure 5 The second direction D2 corresponds to the front-rear direction X of the seat 1 when the fixing member 9 is installed. Figure 5 The fixing member 9 corresponds to the installation state Figure 3 The width direction Y of the seat 1.

[0044] The strip-shaped member constituting the fixing member 9 has a notch 22 formed near the center portion in the second direction D2 by removing the locking portion 13 and the connecting arm portion 14 (see FIG. 2 ). Figures 6-7 ). In the portion where the notch 22 is formed, there is no locking portion 13 and the wrist connecting portion 14. When the user places the finger FR (refer to Fig.12 ) is inserted into the armrest accommodating portion 7, the surface end portion 8a is easily bent upward Z1.

[0045] The skin mounting portion 12 has a shape capable of mounting the skin end portion 8a. Specifically, Figure 5 As shown, there is a portion extending in a straight line in the front-to-back direction X, that is, a flat portion 15 that linearly guides the epidermis end portion 8a toward the rear surface side X2. The epidermis end portion 8a is fixed by sewing in a state of being wrapped around the epidermis mounting portion 12, such as the sewing fixing portion 16. The thickness of the epidermis mounting portion 12 only needs to have a thickness that allows the epidermis end portion 8a to be sewed to the epidermis mounting portion 12. In addition, the epidermis end portion 8a can also be fixed by a fixing method other than the method of sewing and fixing to the epidermis mounting portion 12, for example, by bonding or using metal parts.

[0046] The skin end portion 8a extends from the outer surface 4b11 of the locked portion 4b1 toward the outer side of the upper component 4b of the base 4 ( Figures 4-5The outer skin mounting portion 12 is attached to the locked portion 4b1 while being pulled toward the rear surface side X2 and away from the lower side Z2 of the base body 4. The distal end portion (the end portion on the rear surface side X2) of the outer skin mounting portion 12 is supported by the receiving portion 4a1 of the lower component 4a of the base body 4, and is engaged with the distal end portion by the engaging portion 4a2, so as not to be separated from the receiving portion 4a1.

[0047] The connecting wrist portion 14 has a step portion 21 that is bent in a direction away from the epidermal end portion 8a. Fig.12 ) is inserted into the armrest accommodating portion 7, the surface end portion 8a is easily bent upward Z1.

[0048] like Figure 5 As shown, the locking portion 13 has an outer locking piece 17 and an inner locking piece 18 spaced apart from each other, that is, the outer locking piece 17 abuts against the outer surface 4b11 of the locked portion 4b1 and the inner locking piece 18 abuts against the inner surface 4b12 of the locked portion 4b1. The locking portion 13 locks the locked portion 4b1 in a state where the outer locking piece 17 and the inner locking piece 18 clamp the locked portion 4b1.

[0049] The inner locking piece 18 has an inner protrusion 20 that protrudes toward the inner surface 4b12 of the locked portion 4b1. In the present embodiment, the inner protrusion 20 protrudes toward the inner side of the gap between the outer locking piece 17 and the inner locking piece 18, and is arranged at the base end of the inner locking piece 18. The inner protrusion 20 is in point contact with the inclined surface 4b13 on the distal side (rear surface side X2) of the inner surface 4b12 of the locked portion 4b1 at the position of the contact point CP.

[0050] Furthermore, the inner locking piece 18 has an inclined surface 18 a that is inclined in a direction that is away from the inner surface 4 b 12 of the locked portion 4 b 1 as it goes toward the distal end of the inner locking piece 18 .

[0051] The outer locking piece 17 has a protrusion 19 at its distal end portion 17 a as a reaction force receiving portion that receives the reaction force F2 from the outer surface 4 b 11 of the locked portion 4 b 1 .

[0052] In this embodiment, the reaction force receiving portion includes a convex portion 19 protruding from the distal end portion 17a of the outer locking piece 17 toward the outer surface 4b11 of the locked portion 4b1. The convex portion 19 protrudes toward the inner side of the gap between the outer locking piece 17 and the inner locking piece 18. The rotational moment M1 (refer to Fig.11 ), the protrusion 19 is strongly pressed against the outer surface 4b11 of the locked portion 4b1 and is sunken.

[0053] In addition, in the present embodiment, the distal end portion 17a of the outer locking piece 17 extends in the direction (in the direction in which the outer skin mounting portion 12 extends) of Figure 5 The inclined distal end portion 17a itself can also function as a reaction force receiving portion (ie, included in the reaction force receiving portion).

[0054] In the fixing member 9 of this embodiment, the locking portion 13 locks the locked portion 4b1 in a state where the outer locking piece 17 and the inner locking piece 18 sandwich the locked portion 4b1. In this state, the inner protrusion 20 of the inner locking piece 18 is in point contact with the inclined surface 4b13 on the distal side of the inner surface 4b12 of the locked portion 4b1 at the position of the contact point CP. In addition, the convex portion 19 provided at the distal end portion 17a of the outer locking piece 17 is strongly pressed against the outer surface 4b11 of the locked portion 4b1 and is sunk.

[0055] In addition, if Figure 5 As shown, in the direction along which the epidermis mounting portion 12 and the locking portion 13 are arranged ( Figure 5 The direction perpendicular to the front-to-back direction (X) Figure 5 When observed in the up and down direction Z), the planar portion 15 of the epidermis mounting portion 12 is located at a position farther away from the inner protrusion 20 of the inner locking piece 18 relative to the convex portion 19 of the outer locking piece 17 and the distal end portion 17a which function as the above-mentioned reaction force bearing portion.

[0056] The locking portion 13 is configured to lock the locked portion 4b1 in a state where the locked portion 4b1 is sandwiched between the outer locking piece 17 and the inner locking piece 18, and the tension T (see Figure 8 ), with the contact point CP of the inner protrusion 20 of the inner locking piece 18 as a fulcrum, the convex portion 19 (reaction force receiving portion) on the distal end side of the outer locking piece 17 receives a reaction force F2 (refer to Fig. 9 ) and become the force point.

[0057] like Fig.11 As shown, the convex portion 19 as the reaction force receiving portion is configured to apply a reaction force F2 received from the outer surface 4b11 of the locked portion 4b1 to the skin mounting portion 12 in a direction perpendicular to the direction of the tension T of the skin end portion 8a ( Fig.10The vertical direction Z) is the force F3 in the direction close to the stuck portion 4b1 (upward direction Z1), so that the reaction force that can balance the torque M1 and the torque M2 is applied. The torque M1 is a torque generated by the tension T of the epidermis 8 on the epidermis mounting portion 12 and has the contact point CP of the inner protrusion 20 as the rotation center, and the torque M2 is a torque generated by the force F3 acting on the epidermis mounting portion 12. The specific effects are described in detail below.

[0058] (Features of this embodiment)

[0059] (1) The seat 1 of this embodiment is as follows Figures 4-5 As shown, in Figures 1-2 The center seat 3 of the present invention is provided with a fixing member 9, and the latched portion 4b1 protrudes from the edge 4b31 of the rear surface 4b3 of the upper component 4b of the base 4 toward the rear surface side X2, and is latched to the latched portion 4b1 by the fixing member 9, thereby fixing the skin end 8a to the latched portion 4b1 of the upper component 4b. The fixing member 9 has a structure that the latching portion 13 latched to the latched portion 4b1 is difficult to be disengaged even when the skin mounting portion 12 is subjected to the tension T of the skin 8 in the direction toward the front surface 4b2 of the upper component 4b. Specifically, the latching portion 13 has an outer latching piece 17 abutting against the outer surface 4b11 of the latched portion 4b1 and an inner latching piece 18 abutting against the inner surface 4b12 of the latched portion 4b1, and the latched portion 4b1 is latched in a state where the outer latching piece 17 and the inner latching piece 18 sandwich the latched portion 4b1. The inner locking piece 18 has an inner protrusion 20 protruding toward the inner surface 4b12 of the locked portion 4b1. The outer locking piece 17 has a protrusion 19 at its distal end 17a as a reaction force receiving portion for receiving the reaction force F2 from the outer surface 4b11 of the locked portion 4b1.

[0060] like Figure 8 As shown, the fixing member 9 of this embodiment is locked to the locked portion 4b1 in a state where the skin end portion 8a mounted on the skin mounting portion 12 is pulled and the locking portion 13 clamps the locked portion 4b1 with the outer locking piece 17 and the inner locking piece 18, thereby generating a tension T in the direction (front side X1) toward the front surface 4b2 of the upper component 4b of the base 4 at the skin end portion 8a. Based on the tension T, the inner protrusion 20 of the inner locking piece 18 is pressed (refer to the pressing force F1) against the inner surface 4b12 of the locked portion 4b1 (specifically, the inclined surface 4b13 on the distal end side of the inner surface 4b12) at the position of the contact point CP to become a fulcrum.

[0061] At this time, if Fig. 9As shown, the convex portion 19 (reaction force receiving portion) on the distal end side of the outer locking piece 17 is pressed against the outer surface 4b11 of the locked portion 4b1 and receives the reaction force F2 from the outer surface 4b11, thus becoming a force point. Based on the reaction force F2, the convex portion 19 exerts a force on the skin mounting portion 12 in a direction perpendicular to the direction of the tension T ( Fig.10 denoted by the up-down direction Z1, that is, the force F3 in the direction approaching the locked portion 4b1 (upward direction Z1).

[0062] According to this, if Fig.11 As shown, the rotational moment M1 generated by the tension T of the skin 8 applied to the skin attachment portion 12 and centered at the contact point CP of the inner protrusion 20 and the rotational moment M2 generated by the force F3 acting on the skin attachment portion 12 can be balanced.

[0063] Therefore, in the fixing member 9, the two rotational moments M1 and M2 acting on the skin mounting portion 12 are balanced, so that the fixing member 9 does not rotate. Therefore, the locking portion 13 of the fixing member 9 can maintain a state of being locked to the locked portion 4b1 of the base body by clamping the locked portion 4b1 from the inside and the outside by the outer locking piece 17 and the inner locking piece 18, and the locking portion 13 will not be separated from the locked portion 4b1. Therefore, the locked portion 4b1 does not require a member for preventing it from coming off other than the fixing member 9, so there is no need to increase the number of parts of the seat 1, and the skin end 8a can be stably fixed using only the fixing member 9.

[0064] (2) In the seat 1 of the present embodiment, the reaction force receiving portion includes the convex portion 19 protruding from the distal end portion 17a of the outer locking piece 17 toward the outer surface 4b11 of the locked portion 4b1. Therefore, the convex portion 19 sinks into the outer surface 4b11 of the locked portion 4b1, thereby being able to reliably receive the reaction force F2 from the outer surface 4b11.

[0065] (3) In the seat 1 of the present embodiment, the reaction force receiving portion includes not only the above-mentioned convex portion 19 but also the inclined distal end portion 17a. According to this structure, since the reaction force receiving portion also includes the distal end portion 17a of the outer locking piece 17 which is inclined in the direction toward the outer surface 4b11 of the locked portion 4b1 relative to the direction in which the skin mounting portion 12 extends, the inclined distal end portion 17a and the above-mentioned convex portion 19 are sunk into the outer surface 4b11 of the locked portion 4b1, and the reaction force F2 can be reliably received from the outer surface 4b11.

[0066] In addition, as a modified example of the present invention, even if the outer locking piece 17 does not have the convex portion 19, Fig.13As shown, as long as the reaction force bearing portion includes the distal end portion 17a of the outer locking plate 17 which is inclined in the direction toward the outer surface 4b11 of the locked portion 4b1 relative to the direction of extension of the epidermis mounting portion 12, the inclined distal end portion 17a can be sunk into the outer surface 4b11 of the locked portion 4b1 and can be closely received by the reaction force F2 from the outer surface 4b11.

[0067] Here, in order to make the distal end portion 17a of the outer locking piece 17 inclined in the direction toward the outer surface 4b11 of the locked portion 4b1 relative to the extension direction of the epidermis mounting portion 12, the outer locking piece 17 can be arranged along a line L2, which is inclined in the direction close to the inner locking piece 18 relative to the extension line L1 of the planar portion 15 of the epidermis mounting portion 12.

[0068] (4) In the seat 1 of the present embodiment, the skin attachment portion 12 has the flat surface portion 15 that linearly guides the skin end portion 8a toward the rear surface side X2. According to this structure, since the skin end portion 8a is along the flat surface portion 15 of the skin attachment portion 12 (see Figure 5 ), thereby being able to maintain a uniform appearance of the seat 1.

[0069] (5) In the seat 1 of the present embodiment, the skin end 8a is fixed in a state of being wound around the skin mounting portion 12. According to this structure, the skin end 8a can be firmly fixed to the skin mounting portion 12. In addition, the skin end 8a is connected to other components (in the present embodiment) Figures 3-4 The line of the seam P between the lower constituent parts 4a) of the base body 4 is shown to be easily clear and neat.

[0070] (6) In the seat 1 of the present embodiment, the thickness of the skin attachment portion 12 is such that the skin end portion 8a can be sewn to the skin attachment portion 12. With this structure, it is easy to sew the skin end portion 8a to the skin attachment portion 12. Furthermore, the seam P (see FIG. 1 ) between the skin end portion 8a and the other member (the lower component 4a) is Figures 3-4 ) lines tend to be clearer and neater.

[0071] (7) In the seat 1 of this embodiment, as Figures 3-4 As shown, the base 4 has an armrest accommodating portion 7 for accommodating the armrest 6 at a position adjacent to the outer side (lower side Z2) of the skin end portion 8a. The fixing member 9 is formed by a long strip-shaped member extending along the second direction D2, and the second direction D2 is perpendicular to the first direction D1 (refer to FIG. 1 ) in which the skin mounting portion 12 and the locking portion 13 are arranged. Figure 6 The strip-shaped member constituting the fixing member 9 is formed with a notch 22 formed by removing the locking portion 13 near the center portion in the second direction D2 (the width direction Y of the seat 1 in this embodiment) (see Figures 6-7). Therefore, in order to take out the armrest 6 from the armrest storage portion 7 of the base body, the user of the seat 1 uses the user's finger FR (refer to Fig.12 ) is inserted into the gap between the elbow rest 6 and the skin end 8a, the skin end 8a bends toward the inner side (upper side Z1) of the base 4 at the position of the notch 22 of the fixing member 9, so that it is easy to insert the finger FR into the above-mentioned gap, so that the so-called finger insertion property is improved. Accordingly, the elbow rest 6 can be easily removed from the elbow rest accommodating portion 7.

[0072] (8) In the seat 1 of this embodiment, the fixing member 9 includes a connecting arm portion 14 located between the skin mounting portion 12 and the locking portion 13 and connecting the two. The connecting arm portion 14 has a step portion 21 that is bent in a direction away from the skin end portion 8a. Fig.12 As shown, when the user of the seat 1 inserts the user's finger FR into the gap between the armrest 6 and the surface end 8a in order to take out the armrest 6 from the armrest accommodating portion 7 of the base 4, the surface end 8a bends toward the inner side (upper side Z1) of the base 4 at the step portion 21 of the fixing member 9, so that the finger FR can be easily inserted into the above-mentioned gap, so that the so-called finger insertion property is improved. Accordingly, the armrest 6 can be easily taken out from the armrest accommodating portion 7.

[0073] (9) In the seat 1 of this embodiment, as Figure 5 As shown, the inner locking piece 18 has an inclined surface 18 a inclined in a direction away from the inner surface 4 b 12 of the locked portion 4 b 1 as it goes toward the distal end of the inner locking piece 18 .

[0074] According to this structure, when the locking portion 13 of the fixing member 9 is locked to the locked portion 4b1, the locked portion 4b1 is guided by the inclined surface 18a of the inner locking piece 18. Therefore, the locking portion 13 is easily clamped and locked to the locked portion 4b1 between the inner locking piece 18 and the outer locking piece 17. Therefore, the operability of the operation of locking the fixing member 9 to the locked portion 4b1 is improved.

[0075] (10) In the seat 1 of this embodiment, as Figure 5 As shown, the inner protrusion 20 is arranged at the base end of the inner locking piece 18. According to this structure, when the skin mounting portion 12 is subjected to the tension T of the skin 8 in the direction of the front surface 4b2 of the upper component 4b, the inner protrusion 20 arranged at the base end of the inner locking piece 18 is pressed against the inner surface 4b12 near the distal end of the locked portion 4b1, so that the inner protrusion 20 is in point contact with the inner surface 4b12 of the locked portion 4b1 (refer to the contact point CP) and sinks into the inner surface 4b12, thereby making it difficult for the inner protrusion 20 to deviate and being able to stably play the role of a fulcrum. As a result, the skin end 8a can be fixed more stably.

[0076] (11) In the seat 1 of this embodiment, as Figure 5 As shown, the lower component 4a of the base 4 has an engaging portion 4a2 that engages with the distal end of the epidermis mounting portion 12 of the fixing member 9. According to this structure, the distal end of the epidermis mounting portion 12 of the fixing member 9 is engaged with the engaging portion 4a2 of the lower component 4a of the base 4, thereby preventing the epidermis mounting portion 12 from detaching.

[0077] (12) As described above, the fixing member 9 of this embodiment has a structure in which the locking portion 13 locked to the locked portion 4b1 is not easily disengaged even when the skin mounting portion 12 is subjected to the tension T of the skin 8 in the direction of the front surface 4b2 of the upper component 4b. Specifically, the locking portion 13 includes an outer locking piece 17 abutting against the outer surface 4b11 of the locked portion 4b1 and an inner locking piece 18 abutting against the inner surface 4b12 of the locked portion 4b1, and the locked portion 4b1 is locked in a state where the outer locking piece 17 and the inner locking piece 18 sandwich the locked portion 4b1. The inner locking piece 18 includes an inner protrusion 20 protruding toward the inner surface 4b12 of the locked portion 4b1. The outer locking piece 17 has a convex portion 19 at its distal end portion 17a as a reaction force receiving portion for receiving the reaction force F2 from the outer surface 4b11 of the locked portion 4b1.

[0078] In the fixing member 9 of this embodiment, Figure 8 As shown, the locking portion 13 locks the locked portion 4b1 in a state where the outer locking piece 17 and the inner locking piece 18 clamp the locked portion 4b1 while the skin end portion 8a mounted on the skin mounting portion 12 is pulled, thereby generating a tension T in the direction (front side X1) toward the front surface 4b2 of the upper component 4b of the base 4 at the skin end portion 8a. Based on the tension T, the inner protrusion 20 of the inner locking piece 18 is pressed (refer to the pressing force F1) against the inner surface 4b12 of the locked portion 4b1 (specifically, the inclined surface 4b13 on the distal side of the inner surface 4b12) at the position of the contact point CP to serve as a fulcrum.

[0079] At this time, if Fig. 9 As shown, the convex portion 19 (reaction force receiving portion) on the distal end side of the outer locking piece 17 is pressed against the outer surface 4b11 of the locked portion 4b1 and receives the reaction force F2 from the outer surface 4b11, thus becoming a force point. Based on the reaction force F2, the convex portion 19 exerts a force on the skin mounting portion 12 in a direction perpendicular to the direction of the tension T ( Fig.10 denoted by the up-down direction Z1, that is, the force F3 in the direction approaching the locked portion 4b1 (upward direction Z1).

[0080] According to this, if Fig.11As shown, the rotational moment M1 generated by the tension T of the skin 8 applied to the skin attachment portion 12 and centered at the contact point CP of the inner protrusion 20 and the rotational moment M2 generated by the force F3 acting on the skin attachment portion 12 can be balanced.

[0081] Therefore, the two rotational moments M1 and M2 acting on the skin mounting portion 12 of the fixing member 9 are balanced, so that the fixing member 9 does not rotate. Therefore, the locking portion 13 of the fixing member 9 can maintain the state of clamping the locked portion 4b1 of the base from the inside and the outside by the outer locking piece 17 and the inner locking piece 18 and being locked to the locked portion, and the locking portion 13 will not be separated from the locked portion 4b1. Therefore, the locked portion 4b1 does not need a member for preventing it from coming off other than the fixing member 9, so there is no need to increase the number of parts of the seat 1, and the skin end 8a can be stably fixed using only the fixing member 9.

[0082] <Overview of Implementation>

[0083] The embodiments are summarized as follows.

[0084] The seat of this embodiment includes: a base; a skin covering the front surface of the base; and a skin fixing member that fixes the end of the skin to the base at the edge of the rear surface of the base, wherein the base has a locked portion protruding from the edge of the rear surface of the base to the rear surface side, the locked portion has an outer surface facing the outer side of the base and an inner surface facing the inner side, the end of the skin extends to the rear surface side of the base beyond the locked portion, and the skin fixing member includes: a skin mounting portion, on which the end of the skin is mounted; and a locking portion, which is arranged on a side closer to the locked portion than the skin mounting portion and is locked to the locked portion, the end of the skin is locked to the locked portion through the skin mounting portion, the locking portion has an outer locking piece abutting against the outer surface of the locked portion and an inner locking piece abutting against the inner surface of the locked portion, the inner locking piece has a locking portion facing the The inner protrusion protrudes from the inner surface of the clamped part, and the outer clamping piece has a reaction force bearing portion at its distal end portion that bears the reaction force from the outer surface of the clamped part. The clamping part is constructed as follows: the clamped part is clamped when the outer clamping piece and the inner clamping piece clamp the clamped part, and based on the tension of the epidermis, the reaction force bearing portion receives the reaction force from the outer surface of the clamped part with the inner protrusion as a fulcrum, and the reaction force bearing portion is constructed as follows: based on the reaction force, a force is applied to the epidermis mounting part in a direction perpendicular to the direction of the tension, that is, in a direction close to the clamped part, so as to bear the reaction force that can balance the rotational torque generated by the tension of the epidermis received by the epidermis mounting part and with the inner protrusion as the rotation center, and the rotational torque generated by the force acting on the epidermis mounting part.

[0085] According to this structure, the seat includes a skin fixing member that can fix the end of the skin to the base by being locked to the locked portion protruding from the edge of the rear surface of the base toward the rear surface side. The skin fixing member has a structure in which the locking portion locked to the locked portion is not easy to be disengaged even when the skin mounting portion is subjected to the tension of the skin in the direction toward the front surface of the base. Specifically, the locking portion has an outer locking piece abutting against the outer surface of the locked portion and an inner locking piece abutting against the inner surface of the locked portion. The locked portion is locked in a state where the outer locking piece and the inner locking piece clamp the locked portion. The inner locking piece has an inner protrusion protruding toward the inner surface of the locked portion. The outer locking piece has a reaction force bearing portion at its distal end portion that bears the reaction force from the outer surface of the locked portion.

[0086] The locking portion locks the locked portion when the outer locking piece and the inner locking piece clamp the locked portion, thereby generating tension in the direction toward the front surface of the base at the end of the epidermis. Based on the tension, the inner protrusion is pressed against the outer surface of the locked portion to become a fulcrum, and the reaction force bearing portion is pressed against the outer surface of the locked portion and receives a reaction force from the outer surface to become a force point. The reaction force bearing portion uses the reaction force to apply a force to the epidermis mounting portion in a direction perpendicular to the direction of the tension, that is, in a direction close to the locked portion, thereby bearing a reaction force that can balance the rotational torque generated by the tension of the epidermis received by the epidermis mounting portion and with the inner protrusion as the rotation center, and the rotational torque generated by the force acting on the epidermis mounting portion that becomes the point of action.

[0087] Therefore, in the skin fixing member, the two rotational moments acting on the skin mounting portion are balanced, so that the skin fixing member does not rotate. Therefore, the locking portion of the skin fixing member can maintain a state in which the locked portion of the base body is clamped from the inside and the outside by the outer locking piece and the inner locking piece and is locked to the locked portion, and the locking portion does not detach from the locked portion. Therefore, the locked portion does not require a member for preventing it from coming off other than the skin fixing member, so there is no need to increase the number of parts of the seat, and the end of the skin can be stably fixed using only the skin fixing member.

[0088] In the above-mentioned seat, preferably, the reaction force receiving portion includes a convex portion protruding from a distal end portion of the outer locking piece toward the outer surface of the locked portion.

[0089] According to this structure, since the reaction force receiving portion of the outer locking piece includes a convex portion protruding from the distal end portion of the outer locking piece toward the outer surface of the locked portion, the convex portion sinks into the outer surface of the locked portion and can reliably receive the reaction force from the outer surface.

[0090] In the above-mentioned seat, preferably, the reaction force receiving portion includes a distal end portion of the outer locking piece, and the distal end portion is inclined in a direction toward the outer surface of the locked portion relative to an extending direction of the skin mounting portion.

[0091] According to this structure, since the reaction force bearing portion of the outer locking piece includes a distal end portion of the outer locking piece that is inclined in the direction toward the outer surface of the locked portion relative to the direction of extension of the epidermis mounting portion, the inclined distal end portion is sunk into the outer surface of the locked portion and can reliably receive the reaction force from the outer surface.

[0092] In the above-mentioned seat, preferably, the skin attachment portion has a flat surface portion that linearly guides an end portion of the skin toward the rear surface side.

[0093] According to this structure, since the end of the skin is along the flat surface portion of the skin attachment portion, it is possible to maintain a uniform appearance of the seat.

[0094] In the above-mentioned seat, it is preferable that an end portion of the cover is fixed in a state of being wound around the cover attachment portion.

[0095] According to this structure, since the end of the skin is fixed in a state of being wound around the skin mounting portion, the end of the skin can be firmly fixed to the skin mounting portion. In addition, the seam line between the end of the skin and other members is easy to be clear and neat.

[0096] In the above-mentioned seat, preferably, the skin attachment portion has a thickness sufficient to sew an end portion of the skin to the skin attachment portion.

[0097] According to this structure, the end of the skin can be easily sewn to the skin mounting portion, and the seam line between the end of the skin and other members can be more clear and neat.

[0098] In the above-mentioned seat, preferably: the base has an armrest accommodating portion for accommodating the armrest at a position adjacent to the outer side of the end portion of the skin, the skin fixing member is formed by a long strip-like member extending along a second direction, the second direction being perpendicular to a first direction in which the skin mounting portion and the locking portion are arranged, and the strip-like member is formed with a notch formed near the center portion in the second direction by removing the locking portion.

[0099] According to this structure, a notch is formed near the center of the direction (second direction) in which the strip-shaped member constituting the skin fixing member extends. Therefore, when the user of the seat inserts a finger into the gap between the elbow rest and the end of the skin in order to take out the elbow rest from the elbow rest accommodating portion of the base body, the end of the skin bends toward the inside of the base body at the notch of the skin fixing member, making it easy to insert the finger into the above-mentioned gap, so that the so-called finger insertion property is improved. As a result, the elbow rest can be easily taken out from the elbow rest accommodating portion.

[0100] In the above-mentioned seat, preferably: the base has an elbow rest accommodating portion for accommodating an elbow rest at a position adjacent to the outer side of the end portion of the skin, and the skin fixing member also includes a connecting wrist portion located between the skin mounting portion and the locking portion and connecting the two, and the connecting wrist portion has a step portion bent in a direction away from the end portion of the skin.

[0101] According to this structure, the connecting wrist portion of the skin fixing member, which is located between the skin mounting portion and the locking portion and connects the two, has a step portion, and the step portion is bent in the direction away from the end of the skin. Therefore, when the user of the seat inserts the user's finger into the gap between the elbow rest and the end of the skin in order to take out the elbow rest from the elbow rest accommodating portion of the base body, the end of the skin is bent toward the inside of the base body at the step portion of the skin fixing member, so that the finger can be easily inserted into the above-mentioned gap, so that the so-called finger insertion performance is improved. According to this, the elbow rest can be easily taken out from the elbow rest accommodating portion.

[0102] In the above-mentioned seat, it is preferred that the inner locking piece has an inclined surface which is inclined in a direction away from the inner surface of the locked portion as it moves toward the distal end of the inner locking piece. According to this structure, when the locking portion of the skin fixing member is locked to the locked portion, the locked portion is guided by the inclined surface of the inner locking piece, so that the locking portion is easily clamped and locked between the inner locking piece and the outer locking piece. Therefore, the operability of the operation of locking the skin fixing member to the locked portion is improved.

[0103] In the above-mentioned seat, preferably, the inner protrusion is arranged at a base end portion of the inner locking piece.

[0104] According to this structure, when the skin mounting portion is subjected to the tension of the skin in the direction toward the front surface of the base, the inner protrusion disposed at the base end of the inner locking piece is pressed against the inner surface near the distal end of the locked portion, so that the inner protrusion is in point contact with the inner surface of the locked portion and sinks into the inner surface, thereby making it difficult for the inner protrusion to deviate and being able to stably function as a fulcrum. As a result, the end of the skin can be fixed more stably.

[0105] In the above-mentioned seat, preferably, the base body further includes an engaging portion that engages with a distal end portion of the skin mounting portion of the skin fixing member.

[0106] According to this configuration, the distal end portion of the skin attachment portion of the skin fixing member is engaged with the engagement portion of the base body, thereby preventing the skin attachment portion from being detached.

[0107] The cover fixing component of this embodiment fixes the cover on the front surface of the covering base body in the seat to the clamped part protruding from the edge of the rear surface of the base body toward the rear surface side. The cover fixing component includes: a cover mounting portion having a shape capable of mounting the end of the cover; and a clamping portion, which is clamped to the clamped part of the base body, wherein the clamping portion has an outer clamping piece and an inner clamping piece spaced apart from each other to clamp the clamped part from the inner and outer sides of the base body, the inner clamping piece has an inner protrusion protruding toward the inner side of the gap between the outer clamping piece and the inner clamping piece, and the outer clamping piece has a reaction force bearing portion at its distal end portion that can bear the reaction force from the clamped part, and the cover fixing component is constructed as follows: the outer clamping piece and the inner clamping piece clamp the clamped part through the clamping portion The locked portion is locked in the state of the locking portion, thereby generating tension of the skin at the end of the skin in the direction of the front surface of the base, based on the tension, the inner protrusion is pressed against the inner surface of the locked portion to become a fulcrum, and the reaction force bearing portion is pressed against the outer surface of the locked portion and receives the reaction force from the outer surface to become a force point, and the reaction force bearing portion is constructed as follows: based on the reaction force, a force is applied to the skin mounting portion in a direction perpendicular to the direction of the tension, that is, in a direction close to the locked portion, thereby bearing the reaction force that can balance the rotational torque generated by the tension of the skin received by the skin mounting portion and with the inner protrusion as the rotation center, and the rotational torque generated by the force acting on the skin mounting portion.

[0108] According to this structure, the skin fixing member that fixes the end of the skin to the base of the seat has a structure in which the locking portion that is locked to the locked portion of the base is not easily disengaged even when the skin mounting portion is subjected to tension of the skin in the direction toward the front surface of the base. Specifically, the locking portion has an outer locking piece and an inner locking piece that are spaced apart from each other to form a gap that can clamp the locked portion. The inner locking piece has an inner protrusion that protrudes toward the inside of the gap. The outer locking piece has a reaction force bearing portion at its distal end that can bear the reaction force from the outer surface of the locked portion.

[0109] In the epidermis fixing member, the locking portion locks the locked portion in a state where the outer locking piece and the inner locking piece clamp the locked portion, thereby generating a tension of the epidermis in the direction toward the front surface of the base at the end of the epidermis. Based on the tension, the inner protrusion is pressed against the inner surface of the locked portion to become a fulcrum, and the reaction force receiving portion is pressed against the outer surface of the locked portion and receives a reaction force from the outer surface to become a force point. Based on the reaction force, the reaction force receiving portion applies a force in a direction perpendicular to the direction of the tension, that is, in a direction close to the locked portion, to the epidermis mounting portion, thereby receiving a reaction force that can balance the rotational torque generated by the tension of the epidermis received by the epidermis mounting portion and with the inner protrusion as the rotation center, and the rotational torque generated by the force acting on the epidermis mounting portion.

[0110] Therefore, in the skin fixing member, the two rotational moments acting on the skin mounting portion are balanced so that the skin fixing portion does not rotate. Therefore, the locking portion of the skin fixing member can maintain a state where the locked portion of the base body is clamped from the inside and outside by the outer locking piece and the inner locking piece and is locked to the locked portion, and the locking portion does not detach from the locked portion. Therefore, the end of the skin can be stably fixed using only the skin fixing member without increasing the number of parts of the seat.

[0111] As described above, according to the seat and the cover fixing member of the present embodiment, the end of the cover can be stably fixed using only the fixing member without increasing the number of parts of the seat.
