Description

[Technical field]

[0001] The present invention relates to a vehicle seat. [Background technology]

[0002] One example of a vehicle seat includes a pair of left and right risers fixed to upper rails of left and right slide rails, and a seat cushion supported by the left and right risers via a lifter mechanism. This vehicle seat may further include a connector support member extending in the seat width direction provided between the left and right risers. For example, the connector support member may be configured by a first component fixed to one of the left and right risers, and a second component fixed to the other of the left and right risers and the first component and supporting a connector. Furthermore, the first component and the second component may be riveted together using a rivet gun.

[0003] However, when the connector support member is composed of two components, a first component and a second component, it may be difficult to rivet the first component and the second component using a rivet gun due to the shape of the connector support member.

[0004] It is conceivable to solve this problem by forming the connector support member from three members, a pair of left and right side components and one central component. In this case, the left and right side components are fixed to the left and right risers, respectively. Furthermore, for example, the left side portion of the central component is riveted to the left side component, and the right side portion of the central component is riveted to the right side component.

[0005] [Patent Document 1] JP 2001-57916 A [Patent Document 2] JP 2019-202738 A Summary of the Invention [Problem to be solved by the invention]

[0006] When riveting the side constituent parts and the central constituent part, the worker supports the central constituent part with one hand so that the rivet holes in the side constituent parts and the rivet holes in the central constituent part are concentric. Furthermore, the worker inserts rivets into each rivet hole using a rivet gun held with the other hand. When performing riveting work using a rivet gun, it is necessary to load rivets into the rivet gun. However, it is not easy to load rivets into the rivet gun using only the other hand. In other words, when the connector support member is composed of three members, a problem occurs in that it is not easy for the worker to rivet the side constituent parts and the central constituent part using a rivet gun.

[0007] In consideration of the above-mentioned facts, the present invention aims to provide a vehicle seat that can facilitate rivet fastening work by an operator when a member capable of supporting a connector is composed of a pair of side components fixed to a support member and a central component riveted to each side component. [Means for solving the problem]

[0008] The vehicle seat of the invention described in claim 1 comprises a pair of left and right side components fixed to left and right support members, respectively; a central component fixed to the left and right side components by rivets and to which a connector is fixed; and a temporary support portion capable of temporarily supporting the central component on the left and right side components when the central component is not fixed to the side components by the rivets.

[0009] The vehicle seat according to claim 1 includes a pair of left and right side constituent parts fixed to left and right support members, respectively, and a central constituent part fixed to the left and right side constituent parts by rivets and to which a connector is fixed. The vehicle seat according to claim 1 further includes temporary support parts capable of temporarily supporting the central constituent part on the left and right side constituent parts when the central constituent part is not fixed to the side constituent parts by rivets. Therefore, the worker does not need to support the central constituent part with his or her hands. Therefore, the worker can load rivets into a rivet gun using, for example, both hands. Therefore, the vehicle seat according to claim 1 can facilitate the rivet fastening work by the worker.

[0010] The vehicle seat of the invention described in claim 2 is the vehicle seat described in claim 1, wherein the temporary support portion comprises a pair of left and right first support portions provided on the left and right side constituent portions respectively, a pair of left and right first supported portions provided on the central constituent portion and placed from above on upper surfaces of the left and right first support portions respectively, a pair of left and right second support portions which are upper end surfaces of the pair of left and right first support portions, and a pair of left and right second supported portions placed from above on the pair of left and right second support portions respectively.

[0011] In the vehicle seat according to claim 2, the temporary support portion can be realized with a simple structure.

[0012] The vehicle seat of the invention described in claim 3 is the vehicle seat described in claim 1 or claim 2, in which when a cushion frame having the support member, the side constituent portion, and the central constituent portion is supported by a jig, the central constituent portion is temporarily supported on the side constituent portion by the temporary support portion.

[0013] The vehicle seat according to claim 3 can facilitate riveting work by a worker, which is performed in a state in which the cushion frame including the support members, the side constituent parts, and the central constituent part is supported by a jig. Effect of the Invention

[0014] As described above, the vehicle seat of the present invention can facilitate rivet fastening work by an operator when the member capable of supporting a connector is constructed of a pair of side components fixed to the support member and a central component riveted to each side component.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0016] A vehicle seat 20 according to an embodiment of the present invention will be described with reference to the accompanying drawings. In these drawings, an arrow FR indicates the front side of the seat, an arrow UP indicates the upper side of the seat, and an arrow LH indicates the left side in the seat width direction (left-right direction). In the following description, the front-rear direction, the up-down direction, and the left-right direction are based on a state in which the vehicle seat 20 is installed on the vehicle body floor 11, unless otherwise specified. Meanwhile, the front-rear direction, the up-down direction, and the left-right direction during the assembly work of the seat cushion 39 using a jig 97, as described later, are based on the directions shown in Figs. 6 to 13.

[0017] 1 and 2, a vehicle seat 20 is provided on a vehicle body floor 11, which is a part of the body of a vehicle 10. The vehicle seat 20 is a front seat. The vehicle seat 20 includes lower rails 21, upper rails 22, a riser (support member) 23, a lifter mechanism 25, and a seat body 37.

[0018] A pair of left and right lower rails 21 extending in the front-rear direction are fixed to the upper surface of the vehicle body floor 11. A pair of left and right upper rails 22 are slidably supported on each lower rail 21. Each upper rail 22 is further provided with a slide lock device (not shown) that restricts or allows the upper rail 22 to slide relative to the lower rail 21. Furthermore, a pair of left and right risers 23 are fixed to the left and right upper rails 22, respectively.

[0019] The left and right risers 23 are provided with a lifter mechanism 25. The lifter mechanism 25 has a pair of left and right front links 27, a connecting pin 28, a rear link 32, a connecting pin 33, a front shaft 29, and a rear shaft 34. The lower ends of the left and right front links 27 are rotatably connected to the front ends of the left and right risers 23 via the connecting pins 28 extending in the seat width direction. The lower ends of the left and right rear links 32 are rotatably connected to the rear parts of the left and right risers 23 via the connecting pins 33 extending in the seat width direction. Furthermore, both ends of a metal front shaft 29 extending in the seat width direction are inserted into mounting holes 27a provided in the left and right front links 27, respectively, and both ends are fixed to the front links 27. Furthermore, a metal rear shaft 34 extending in the seat width direction penetrates the upper ends of the left and right rear links 32 so as to be rotatable about its own axis.

[0020] An upper portion of the lifter mechanism 25 supports a seat body 37. The seat body 37 has a seat cushion 39, a seat back (not shown), and a headrest (not shown).

[0021] The seat cushion 39 has a metal cushion frame 40 that is a framework member, a cushion pad (not shown) that covers the cushion frame 40, and a bag-shaped covering material (not shown). The cushion frame 40 has a pair of left and right side frames 41, and a front frame 42 that connects front ends of the left and right side frames 41 together. Furthermore, both ends of the rear shaft 34 are fixed to rear ends of the left and right side frames 41, respectively.

[0022] A four-joint link mechanism is formed by the riser 23, the front link 27, the rear link 32 and the side frame 41, and the seat cushion 39 moves up and down relative to the left and right risers 23 as this four-joint link mechanism operates.

[0023] 2 to 7, a metallic connector support member 45 is provided at the front of the left and right risers 23. The connector support member 45 includes a first side bracket (side component) 47, a second side bracket (side component) 63, and a connector bracket (central component) 75. The first side bracket 47, the second side bracket 63, and the connector bracket 75 are all manufactured by press forming a metal plate.

[0024] As shown in Figs. 5 and 7, the first side bracket 47, which is the left bracket, includes a base 48 and a fixed portion 59. The base 48 includes a flat plate portion 49 that is substantially perpendicular to the up-down direction, and an inclined support portion 51 that is connected to the front edge of the flat plate portion 49 and is inclined with respect to the flat plate portion 49. A protrusion 53 is provided at the right end of the flat plate portion 49, and a positioning groove 54 that is a downward recess is provided on the upper surface of the protrusion 53. The planar shape of the positioning groove 54 is substantially U-shaped. More specifically, the left-right dimension of the positioning groove 54 widens toward the front (open end). Furthermore, a first rivet hole 56 and a second rivet hole 57 are provided in the flat plate portion 49 in a line in the front-rear direction. The first rivet hole 56 and the second rivet hole 57 are the same circular shape. The fixed portion 59 is substantially perpendicular to the flat plate portion 49. As shown in FIG. 4, the fixed portion 59 of the first side bracket 47 is fixed to the side surface of the left riser 23 .

[0025] As shown in Fig. 5 and Fig. 7, the second side bracket 63, which is the bracket on the right side, includes a base 64 and a fixed portion 70. The base 64 has a flat plate portion 65 that is substantially perpendicular to the up-down direction, and an inclined support portion (temporary support portion) (first support portion) 67 that is connected to the front edge of the flat plate portion 65 and is inclined relative to the flat plate portion 65. A circular rivet hole 69 is provided in the flat plate portion 65. The fixed portion 70 is substantially perpendicular to the base 64. As shown in Fig. 3, the fixed portion 70 of the second side bracket 63 is fixed to the side surface of the right riser 23.

[0026] As shown in Fig. 5, the connector bracket 75, which is the central bracket, is a plate-like member having a substantially rectangular shape elongated in the left-right direction. A first flat plate-like portion 77 and a second flat plate-like portion 86, both of which are substantially perpendicular to the up-down direction and located on the same plane as each other, are formed at the rear of the connector bracket 75. The first flat plate-like portion 77 is provided with a punched hole 78 and a locking protrusion 79 formed during press molding. The locking protrusion 79 is a portion connected to the left edge of the punched hole 78 and has a substantially L-shaped cross section. The locking protrusion 79 includes a connection portion 80 that is parallel to the first flat plate-like portion 77 and is connected to the left edge of the punched hole 78, and a locking portion 81 that extends upward from the right end of the connection portion 80.

[0027] Furthermore, the first flat plate portion 77 is provided with a first rivet hole 83 and a second rivet hole 84 aligned in the front-to-rear direction. As is clear from Fig. 7, the first rivet hole 83 and the second rivet hole 84 are both circular. The first rivet hole 83 of the connector bracket 75 has substantially the same diameter as the first rivet hole 56 of the first side bracket 47. On the other hand, the second rivet hole 84 of the connector bracket 75 has a larger diameter than the second rivet hole 57 of the first side bracket 47 and the first rivet hole 83 of the connector bracket 75. The second flat plate portion 86 is formed with a rivet hole 87 which is an elongated hole extending in the left-right direction.

[0028] 5, a connector 43 is fixed to the lower surface of the second flat plate portion 86. One end of a cable 44 is connected to the connector 43. Note that power is supplied to the cable 44 from a battery (not shown).

[0029] The front of the connector bracket 75 is formed with a front inclined portion 89 inclined with respect to the rear. Furthermore, a flange portion 89a is provided on the periphery of the front inclined portion 89. A first cutout portion 90 is formed on the left edge of the front inclined portion 89, the flange portion 89a, and the first flat plate portion 77, and a second cutout portion 91 having a bilaterally symmetrical shape with the first cutout portion 90 is formed on the right edge of the front inclined portion 89, the flange portion 89a, and the second flat plate portion 86. The end face of the portion formed on the flange portion 89a of the first cutout portion 90 is formed with a first supported portion (temporarily supported portion) (second supported portion) 90a that is substantially parallel to the left-right direction in a plan view. The end face of the portion formed on the flange portion 89a of the second cutout portion 91 is formed with a second supported portion (temporarily supported portion) (second supported portion) 91a that is substantially parallel to the left-right direction in a plan view. Furthermore, at both left and right ends of the front inclined portion 89, a first inclined supported portion (temporarily supported portion) (first supported portion) 93 and a second inclined supported portion (temporarily supported portion) (first supported portion) 94 are provided, which are inclined relative to the first flat plate portion 77 and the second flat plate portion 86.

[0030] (Action and Effects) Next, the operation and effects of this embodiment will be described.

[0031] A procedure for assembling the seat cushion 39 by one worker (not shown) using a rivet gun 98 (see FIG. 7) and a number of rivets will be described. More specifically, a procedure for fixing the connector bracket 75 to the first side bracket 47 and the second side bracket 63 using the rivet gun 98 will be described in a state in which the seat cushion 39 is supported by a pair of left and right jigs 97 installed on a work surface 96 as shown in FIG. 6. The following description of the front-rear direction, the up-down direction, and the left-right direction in the description of the assembly procedure is based on the directions defined by FR, LH, and UP shown in FIGS. 6 to 13. That is, at this time, the front shaft 29 is positioned above the rear shaft 34. Furthermore, the jig 97 restricts the left and right upper rails 22 from sliding relative to the lower rails 21.

[0032] First, as shown in FIG. 7, an operator brings both left and right ends of the connector bracket 75 held by hand close to the first side bracket 47 and the second side bracket 63 from the front.

[0033] 7 to 9, the operator places the upper part of the connector bracket 75 held by hand over the first side bracket 47 and the second side bracket 63 from above. More specifically, as shown in FIG. 8, the lower surface of the first inclined supported part 93 is placed on the upper surface of the inclined support part (temporarily supported part) (first support part) 51 while the first flat part 77 of the connector bracket 75 is moved forward away from the flat part 49 of the first side bracket 47, and the first supported part 90a of the first cutout part 90 is brought into contact with the support end surface (temporarily supported part) (second support part) 51a, which is the upper end surface of the inclined support part 51. Furthermore, although not shown in the drawings, at this time, the rear end part of the locking projection 79 (locking part 81) is located forward of the flat part 49 (positioning groove 54). Furthermore, as shown in Figure 9, with the second flat portion 86 of the connector bracket 75 moved forward away from the flat portion 65 of the second side bracket 63, the lower surface of the second inclined supported portion 94 is placed on the upper surface of the inclined support portion 67, and the second supported portion 91a of the second cutout portion 91 is brought into contact with the support end surface (temporary support portion) (second support portion) 67a, which is the upper end surface of the inclined support portion 67.

[0034] When the upper part of the connector bracket 75 is placed from above over the first side bracket 47 and the second side bracket 63 in this manner, the connector bracket 75 is temporarily supported by the first side bracket 47 and the second side bracket 63 as shown in Figures 7 to 9. Therefore, even if the worker removes both hands from the connector bracket 75, the support state of the connector bracket 75 by the first side bracket 47 and the second side bracket 63 is maintained.

[0035] Next, the worker holds the rivet gun 98 with one hand and loads one rivet into the rivet gun with the other hand. In other words, the worker can load the rivet into the rivet gun using both hands while keeping both hands away from the connector bracket 75.

[0036] Next, as shown in Fig. 10, the worker grasps the connector bracket 75 with his / her hand and moves the connector bracket 75 upward relative to the first side bracket 47 and the second side bracket 63 from the position shown in Figs. 7 to 9. Furthermore, while inserting the locking portion 81 of the locking projection 79 into the positioning groove 54 as shown in Fig. 10, the worker moves the lower surface of the first inclined supported portion 93 upward from the upper surface of the inclined support portion 51 while bringing the first flat plate portion 77 into contact with the front surface of the flat plate portion 49 as shown in Fig. 11. Furthermore, the worker moves the lower surface of the second inclined supported portion 94 upward from the upper surface of the inclined support portion 67 while bringing the second flat plate portion 86 into contact with the front surface of the flat plate portion 65 as shown in Fig. 12.

[0037] 10, the worker moves the connector bracket 75 by a small amount so that the first rivet hole 56 of the first side bracket 47 and the first rivet hole 83 of the connector bracket 75 are substantially concentric, and the second rivet hole 57 of the first side bracket 47 is positioned immediately behind the second rivet hole 84 of the connector bracket 75. The first side bracket 47 and the connector bracket 75 are designed so that the first rivet hole 56 of the first side bracket 47 and the first rivet hole 83 of the connector bracket 75 are substantially concentric when the lower surface of the locking portion 81 contacts the bottom portion 54a. However, if a manufacturing error occurs in at least one of the first side bracket 47 and the connector bracket 75, the first rivet hole 56 of the first side bracket 47 and the first rivet hole 83 of the connector bracket 75 will be substantially concentric when a small gap is formed between the lower surface of the locking portion 81 and the bottom portion 54a. Furthermore, first rivet hole 56 and first rivet hole 83 function as reference holes. That is, when first rivet hole 56 and first rivet hole 83 are substantially concentric, second rivet hole 57 of first side bracket 47 and second rivet hole 84 of connector bracket 75 are substantially concentric, as shown in Fig. 10. More specifically, second rivet hole 57 of first side bracket 47, which has a smaller diameter than second rivet hole 84 of connector bracket 75, is located more inward than second rivet hole 84. Furthermore, as shown in Fig. 10, rivet hole 87 of connector bracket 75 and rivet hole 69 of second side bracket 63 face each other in the front-rear direction.

[0038] Next, the worker uses rivet gun 98 held in the other hand to drive rivet 99A into first rivet hole 83 and first rivet hole 56 (see FIG. 13). As a result, even if the worker releases his / her hand from connector bracket 75, the relative positions of first side bracket 47, second side bracket 63, and connector bracket 75 are temporarily held in the positions shown in FIG.

[0039] Therefore, even if the worker releases connector bracket 75, there is little risk that connector bracket 75 will rotate counterclockwise in Fig. 10 around rivet 99A. Even if connector bracket 75 rotates counterclockwise in Fig. 10 around rivet 99A by a small angle, the lower surface of locking portion 81 comes into contact with bottom portion 54a of positioning groove 54, restricting further rotation of connector bracket 75.

[0040] The operator then holds the rivet gun 98 in one hand and loads a single rivet into the rivet gun with the other hand.

[0041] Next, the worker uses rivet gun 98 held in either hand to drive rivet 99B into rivet hole 87 in connector bracket 75 and rivet hole 69 in second side bracket 63 (see FIG. 13). As a result, even if the worker releases his / her hand from connector bracket 75, the rivet 99B will hold the area around rivet hole 69 in second side bracket 63 and the area around rivet hole 87 in connector bracket 75 in the state shown in FIG.

[0042] The operator then holds the rivet gun 98 in one hand and loads a single rivet into the rivet gun with the other hand.

[0043] Next, the worker uses rivet gun 98 held with either hand to drive rivet 99C into second rivet hole 84 of connector bracket 75 and second rivet hole 57 of first side bracket 47. This completes the work of fastening connector bracket 75 to first side bracket 47 and second side bracket 63 using rivets 99A, 99B, 99C. Hereinafter, the integrated body supported by jig 97 in this state will be referred to as cushion intermediate body 100.

[0044] Thereafter, the worker connects a connector provided at an end of a cable (harness) of an electric motor (not shown) for applying a driving force to the lifter mechanism 25 provided on the cushion intermediate body 100 to the connector 43. This operation is performed in a state where the cushion intermediate body 100 is supported by the jig 97, or in a state where the lower rail 21 of the cushion intermediate body 100 separated from the jig 97 is placed on the work surface 96.

[0045] Thereafter, the worker covers the cushion intermediate body 100 with a cushion pad, and further covers the surfaces of the cushion intermediate body 100 and the cushion pad with a covering material. In this way, the seat cushion 39 is completed.

[0046] Furthermore, the lower end of the seat back is connected to the rear end of the seat cushion 39, and a headrest is provided at the upper end of the seat back, thereby completing the vehicle seat 20.

[0047] As described above, the vehicle seat 20 of this embodiment includes the inclined support portion 51 (support end surface 51a), the inclined support portion 67 (support end surface 67a), the first supported portion 90a, the second supported portion 91a, the first inclined supported portion 93, and the second inclined supported portion 94, which are temporary support portions capable of temporarily supporting the connector bracket 75 on the first side bracket 47 and the second side bracket 63 when the connector bracket 75 is not fixed to the first side bracket 47 and the second side bracket 63 by the rivets 99A, 99B, and 99C. Therefore, when the connector bracket 75 is temporarily supported on the first side bracket 47 and the second side bracket 63, the worker does not need to support the connector bracket 75 with his / her hands. Therefore, the worker can load rivets into the rivet gun 98 with both hands.

[0048] 10 by rivet 99A, if the lower surface of locking portion 81 faces bottom 54a of positioning groove 54 with a small gap therebetween or the lower surface of locking portion 81 comes into contact with bottom 54a, even if the worker removes his / her hand from connector bracket 75, rivet hole 87 of connector bracket 75 and rivet hole 69 of second side bracket 63 will face each other in the front-rear direction, and second rivet hole 57 of first side bracket 47 and second rivet hole 84 of connector bracket 75 will be substantially concentric. Therefore, with his / her hand removed from connector bracket 75, the worker can drive rivet 99B into rivet hole 69 of second side bracket 63 and rivet hole 87 of connector bracket 75 using rivet gun 98 held in hand. Therefore, the worker can easily drive the rivets 99B into the rivet holes 87 of the connector bracket 75 and the rivet holes 69 of the second side bracket 63.

[0049] Furthermore, with second rivet hole 57 in first side bracket 47 positioned more inward than second rivet hole 84 in connector bracket 75, second rivet hole 57 and second rivet hole 84 are substantially concentric. This allows the worker to visually check the periphery of second rivet hole 57 in first side bracket 47 and second rivet hole 84 in connector bracket 75. This allows the worker to very easily drive rivets 99C into second rivet hole 57 in first side bracket 47 and second rivet hole 84 in connector bracket 75 using rivet gun 98 held in hand while releasing the connector bracket 75.

[0050] In this manner, the vehicle seat 20 of this embodiment can facilitate the riveting work of the first side bracket 47, the second side bracket 63, and the connector bracket 75 using the rivet gun 98 by a worker.

[0051] Furthermore, the temporary support portion is realized by a simple configuration including the inclined support portion 51 (support end surface 51a), the inclined support portion 67 (support end surface 67a), the first supported portion 90a, the second supported portion 91a, the first inclined supported portion 93, and the second inclined supported portion 94. Therefore, there is little risk that the manufacturing cost of the seat cushion 39 will increase significantly due to the provision of the temporary support portion.

[0052] Although the embodiment of the present invention has been described above, the present invention is not limited to the above embodiment.

[0053] For example, the second side bracket 63 may be secured to the riser 23 on the left side, and the first side bracket 47 may be secured to the riser 23 on the right side.

[0054] The first side bracket 47 and the second side bracket 63 may be fixed to a seat component (support member) different from the riser 23 .
