Hereinafter, embodiments of the present invention will be described with reference to the drawings. The front-rear, left-right and up-down directions follow the front-rear, left-right and up-down directions of the vehicle.

As shown in FIG. 1, the seat 1 is used as a driver's seat or a passenger seat of a vehicle, and has a seat cushion 2, a seat back 3, and a headrest 4. The seat cushion 2 is supported by a pair of left and right slide rails 6 and 6 fixed to a floor 5 of a vehicle cabin so as to be slidable back and forth. The sheet 1 also has a flexible pad 9 made of urethane foam or the like, which is arranged on the frame 7 and the support member 8 (see FIG. 2), and a skin material 10 that covers the pad 9. The slide rail 6 includes a lower rail 11 coupled to the floor 5, an upper rail 12 supported by the lower rail 11 so as to be slidable back and forth, and a rail cover 13 (see FIG. 3) that covers at least a part of the upper rail 12. ..

As shown in FIG. 2, the seat cushion 2 is supported by the frame 7 and the frame 7 so as to be positioned inside the frame 7, and the seat cushion 2 is seated via a skin material 10 and a pad 9 (see FIG. 1 ). The supporting member 8 elastically supports the load of one passenger.

The frame 7 includes a pair of left and right side members 14, 14, a front cross member 15 that connects the front end portions of the pair of left and right side members 14 and 14 to each other, and a rear end portion of the pair of left and right side members 14 and 14 to each other. It has a rear cross member 16 to be connected, and a pan frame 17 which is connected to the front end portions of the pair of left and right side members 14 and whose left and right intermediate portions are located in front of the front cross member 15. The pair of left and right side members 14 and 14 are long members made of sheet metal and long in the front and back, and flanges are formed on the upper and lower sides. The side member 14 is supported by the upper rail 12 via the base member 65 (see FIG. 3). The front cross member 15 and the rear cross member 16 are metal pipes extending in the left-right direction. The pan frame 17 is made of sheet metal and has a surface generally along the front portion of the seat surface. As shown in FIG. 4, a position sensor 19 that detects the front-rear position of the seat 1 with respect to the floor 5 is attached to the right side member 14.

As shown in FIG. 2, the support member 8 includes a plate-shaped main body 20 that extends substantially parallel to the frame 7, and a slope that extends outward from the left and right side edges of the rear portion of the main body 20 by tilting to the front side. The portion 21, the front attachment portion 22 that extends forward from the front edge of the main body 20 and engages with the front cross member 15, and the rear attachment member 22 that extends obliquely upward and rearward from the rear edge of the main body 20. And a rear mounting portion 23 for mating. The support member 8 is formed of a resin in which the metal wire 24 is insert-molded, bends under the load of the occupant, and elastically supports the occupant.

A sensor mounting portion 26 on which the pressure sensor 25 is mounted is formed on the front side of the central portion of the front portion 50 of the main body 20 in the left-right direction. The pressure sensor 25 detects the pressure applied to the seat cushion 2 in order to determine whether the occupant is seated on the seat 1. At the rear portion of the main body 20, the load of the occupant is dispersed by the inclined portion 21, so that the pressure applied when sitting is reduced. Therefore, the pressure sensor 25 is arranged at a position offset forward with respect to the inclined portion 21 so as not to be affected by the pressure distribution by the inclined portion 21. Therefore, the accuracy of the seating determination by the seating determining means (not shown) such as the ECU that receives the signal from the pressure sensor 25 is improved.

The seat 1 (see FIG. 1) employs an air ventilation system that sucks or blows air to the surface of the seat 1 to adjust the humidity. , A pair of air openings 27, 27 that are vertically penetrated to form air passages. Each air opening 27 has a rectangular shape in a plan view. A central vertical wire 24a for reinforcement, which passes along the vertical direction, is embedded in the resin portion formed by the sensor mounting portion 26 sandwiched between the pair of air openings 27, 27.

Further, in the rear portion of the main body 20, there is a through hole that locks a plurality of hooks 28 (see FIG. 5) attached to the end portion of the skin material 10 and adjusts the bending of the support member 8. A central locking hole 29 located at the center and a pair of side locking holes 30, 30 positioned on the left and right of the central locking hole 29 are provided. The central locking hole 29 and the pair of side locking holes 30, 30 each have a rectangular shape in a plan view. The center locking hole 29 and the pair of side locking holes 30 and 30 arranged in the left-right direction have the same width in the front-rear direction, but the length in the left-right direction is larger in the center locking hole 29 than in the pair. It is longer than the side engaging holes 30, 30. Therefore, the flexibility of the central portion of the support member 8 is increased, and the sitting comfort is soft. By making the length of the central locking hole 29 and the length of the pair of side locking holes 30, 30 different from each other in this way, the bending of the support member 8 is set so as to improve the seating feeling. Further, the strength of the periphery of the central locking hole 29 is reinforced by the central vertical wire 24a vertically cutting the center of the central locking hole 29 in the left-right direction. As shown in FIG. 5A, the hook 28 that is locked in the central locking hole 29 has a slot 31 that receives the central vertical wire 24 a, so that the hook 28 engages with the central locking hole 29. Becomes stronger. Further, since the slot 28 is provided, the hook 28 locked in the central locking hole 29 has a different shape and a wider width than the hook 28 locked in the side locking hole 30. By changing the shape and size of the hook 28 according to the shape and size of the locking hole to be locked in this manner, it is possible to prevent the worker from assembling the hook 28 into the wrong locking hole. Since the central locking hole 29 and the pair of side locking holes 30, 30 are separated from the rear mounting portion 23, workability is good. Since the skin material 10 can be locked to the support member 8, there is no need to provide a projecting piece or the like for forming the locking portion on the frame 7, and the frame 7 can be made smaller and lighter.

As shown in FIGS. 2 and 5, at the rear edge of the central locking hole 29 and the pair of side locking holes 30, 30 on the front side of the main body 20, there is a hook recess 32 recessed toward the back side. It is provided. The hook 28 passes through the corresponding central locking hole 29 or side locking hole 30 from the back side to the front side, and the tip of the hook 28 is received in the hook recess 32. By receiving the tip of the hook 28 in the hook recess 32, the hook 28 can be positioned with respect to the central locking hole 29 and the side locking hole 30. Instead of the hook recess 32, as shown in FIG. 5C, a hook edge wall 33 projecting to the front side is provided at the front rear edge of the central locking hole 29 so that the hook 28 has a hook. The tip may be locked (the same applies to the front edge of the side locking hole 30). By engaging the tip of the hook 28 with the hook edge wall 33, the hook 28 is prevented from coming off from the central locking hole 29 and the side locking hole 30. Further, since the central locking hole 29 and the side locking hole 30 are provided at a position aligned with the pair of left and right inclined parts 21, 21 of the main body 20, that is, at a position where the rigidity is relatively high, the central locking hole It is possible to suppress the deformation of the side locking holes 29 and the side locking holes 30 and prevent the hooks 28 from coming off from the central locking holes 29 and the side locking holes 30.

As shown in FIGS. 2, 3, and 6 to 8, the inclined portion 21 is formed with a tubular portion 34 that protrudes downward (backward in the direction perpendicular to the main body 20). The mounting hole 35 formed in the inner space of the cylinder of the cylindrical portion 34 allows a clip 37 for mounting another member to the support member 8 to be inserted therethrough. A shoulder surface 38 is formed on the inner peripheral surface of the tubular portion 34 to increase the rigidity of the tubular portion 34 and to lock the tip of the clip 37. For example, the tubular portion 34 includes a bottom wall 34a having a through hole through which the clip 37 is inserted and having a rectangular shape in a plan view, and a side wall 34b standing upward from a side portion of the bottom wall 34a. .. The upper surface of the bottom wall 34a constitutes the shoulder surface 38. Since the lower end of the tubular portion 34 is located substantially on the same plane as the back surface of the main body 20 and the extending direction of the mounting hole 35 is perpendicular to the main body 20, the clip 37 is attached to the inclined portion 21 from the back surface side. The work can be performed in the same manner as the mounting work for the main body 20. That is, the workability of attaching the clip 37 to the tubular portion 34 is improved as compared with the case where the clip 37 is attached while being inclined. Further, by having the shoulder surface 38, the tip of the clip 37 does not project from the surface of the inclined portion 21, and it is possible to prevent the clip 37 from affecting the seating feeling. The positions of the central locking hole 29 and the pair of side locking holes 30, 30 in the front-rear direction are deviated from the hanging position 10 a of the skin material 10 provided on the pad 9. Further, when the skin material 10 is fixed to the side member 14, the fixing position is displaced forward and backward with respect to the inclined portion 21.

A grid-like reinforcing portion 39 is provided on the back surface of the inclined portion 21. The lattice-shaped reinforcing portion 39 has a plurality of vertical ribs 40 projecting downward and extending in the front-rear direction, and a plurality of horizontal ribs 41 projecting downward and extending laterally along the inclined portion. Since the rigidity of the inclined portion 21 is improved by the lattice-shaped reinforcing portion 39, the deformation of the inclined portion 21 can be suppressed, and the position of the support member 8 with respect to the frame 7 is constant. The tubular portion 34 is disposed in the lattice-shaped reinforcing portion 39, and in order to compensate for the reduction in rigidity due to the provision of the mounting holes 35, some vertical ribs 40 and/or horizontal ribs 41 are connected to the tubular portion 34. It is preferable. A lower edge of a portion of the lateral rib 41 connected to the tubular portion 34, which is disposed inward of the tubular portion 34 in the left-right direction, has the same height as the lower end of the tubular portion 34 or the lower end of the tubular portion 34. Is also located below. This portion of the lateral rib 41 improves the rigidity of the entire tubular portion 34 by the vertical length. Further, this portion of the lateral rib 41 may include the rib wire 24f. The rib wire 24f is preferably located at the same height as the lower end of the tubular portion 34 or below the lower end of the tubular portion 34. Since the central locking hole 29 and the side locking hole 30 are provided with the tubular portion 34 reinforced by the vertical ribs 40 and the horizontal ribs 41 in the lateral direction, the central locking hole 29 and the side locking hole 30 are secured. The rigidity around the hole 30 is also improved.
Further, as in the modification shown in FIG. 11, in order to increase the rigidity of the inclined portion 21, the hole annular wire 24g may be arranged so as to surround the tubular portion 34. In this case, the wires 24 are preferably arranged so as to intersect the vertical ribs 40 and the horizontal ribs 41.

As shown in FIG. 4, side notches 49 are formed on the left and right side edges of the support member 8 between the main body 20 and the inclined portion 21 provided on the rear portion. The position of the position sensor 19 attached to the side member 14 in the front-rear direction is within the position of the side cutout 49 in the front-rear direction. By providing the side cutouts 49, the support member 8 can be made smaller and lighter, and the mounting state of the position sensor 19 can be easily confirmed. The side cutouts 49 may be provided only on the left and right side edges of the support member 8 on which the position sensors 19 are provided. In addition, except that the position sensor 19 is provided only on one of the left and right sides, the frame 7 and the support member 8 are substantially mirror-image symmetrical with respect to a central plane orthogonal to the left-right direction.

Since the inclined portion 21 is not provided in front of the side cutout 49, the side edge of the main body 20 is the side edge of the support member 8 in the front portion 50 of the support member 8. The front-rear length of the front portion 50 is shorter than the front-rear length of the inclined portion 21, and the lateral outer edge of the front portion 50 is located inward of the lateral outer edge of the inclined portion 21. Therefore, the load applied to the front part is reduced, and the load applied to the rear part is dispersed laterally, so that the strength of the support member is improved as a whole. Further, the front portion 50 of the main body 20 has a crank shape 50a whose front side is lower than rear side in side view, and supplements the rigidity reduced by the side cutout 49. Since the front of the crank shape 50a is lower than the rear, the load on the legs of the occupant is small. Further, when another member is attached to the back side of the lowered portion of the crank shape 50a, the influence of the tip of the clip (not shown) protruding from the front side is mitigated by the raised portion of the crank shape 50a, and the seating feeling is reduced. Is suppressed. Further, since the occupant's buttocks are supported on the rear side even if the front side is lowered, the crank shape 50a has a small influence on the buttocks support, and a reduction in seating feeling is suppressed. Further, the left and right outer vicinity portions of the pair of left and right air openings 27, 27 of the main body 20 are bent so as to be bent in a front view so as to be connected to a portion of the front portion 50 of the main body 20 lowered by the crank shape 50a. It has a part 51. The bent portion 51 extends from the vicinity of the air opening 27 to the vicinity of the front edge of the main body 20. The bent portion 51 compensates for the rigidity reduced by the pair of left and right air openings 27, 27. The crank shape 50a, the bent portion 51, and the front wall portion 50b extending outward in the left-right direction from the front end of the bent portion 51 define recesses 50c on the front sides of the left and right side portions of the front portion 50. Since the rigidity of the periphery of the recess 50c is improved, the mounting stability of the front mounting portions 22 arranged on both left and right sides to the front cross member 15 is improved. Ribs 50d extending in the front-rear direction and the left-right direction may be provided on the surface of the recess 50c.

As shown in FIGS. 3 and 4, in order to increase the rigidity of the left and right side edges of the support member 8, a flange 53 projecting to the front side is provided on the side edge of the front portion 50 of the main body 20, and the side of the inclined portion 21 is provided. A flange 54 is provided at the edge so as to project to the back side. The flange 53 is continuous at least in the front-back direction range in which the bent portion 51 extends. In order to improve rigidity, the rear end side of the flange 53 may extend to a portion of the inclined portion 21 where the side cutout 49 is formed. When a clip (not shown) is attached to the hole 55 provided near the front side edge of the main body 20, the tip of the clip projects to the front side of the main body 20. The flange 53 projecting to the front side mitigates the influence on the seating feeling due to the projection of the tip of the clip. On the other hand, since the shoulder surface 38 is provided in the attachment hole 35 of the inclined portion 21, the tip of the clip 37 attached to the attachment hole 35 does not project to the front side of the inclined portion. Therefore, the flange 54 of the inclined portion is projected to the back side so as not to affect the seating feeling.

As shown in FIG. 2, some of the wires 24 embedded in the resin forming the support member 8 extend in the left-right direction (lateral direction), and the rigidity of the periphery of the support member is increased. .. The front transverse wire 24c is arranged in front of the pair of left and right air openings 27, 27 approximately along the front edge of the main body 20, and the pair of left and right air openings 27, 27 and the central locking hole 29, A central transverse wire 24d is arranged between the left and right pair of side engaging holes 30, 30 and is generally behind the main body 20 behind the central engaging hole 29 and the left and right pair of side engaging holes 30, 30. The rear transverse wire 24e is arranged at a position along the edge. A part of the central lateral wire 24d is arranged along the front edges of the central locking hole 29 and the pair of left and right side locking holes 30, 30.

The front mounting portion 22 is engaged with the front cross member 15 from above and has three front mounting pieces 56 separated from each other for easy mounting. Similarly, the rear mounting portion 23 has three rear mounting pieces 57 that are engaged with the rear cross member 16 from above and are separated from each other for easy mounting. Both ends of the central vertical wire 24a and the side vertical wires 24b are embedded in the corresponding front mounting piece 56 and rear mounting piece 57, respectively, and reinforce the front mounting portion 22 and the rear mounting portion 23.

A front notch 58 is provided in a portion of the front edge of the main body 20 which is not connected to the front attachment piece 56. The width of the front cutout 58 in the left-right direction is smaller than the distance between two adjacent front attachment pieces 56, 56 connected to the front edge of the main body 20. Therefore, the contour of the space defined by the front edge of the main body 20 and the two front attachment pieces 56, 56 adjacent to each other has a convex shape in a plan view. By providing the front notch 58, a portion from the vicinity of the front edge of the main body 20 to the front attachment piece 56 can be largely bent, and the front attachment piece 56 can be easily attached to the front cross member 15. Become. Further, since the width of the front notch 58 is smaller than the distance between the two front mounting pieces 56 adjacent to each other, the reduction in seating feeling due to the provision of the front notch 58 is suppressed. Further, between the sensor mounting portion 26 and the central front attachment piece 56 is a connecting portion 59 in which the central vertical wire 24a is embedded. Since the air opening 27 and the front notch 58 are provided, the rigidity of the front part of the main body 20 near the center in the left-right direction is reduced, but the connection part 59 ensures the necessary rigidity. The front attachment piece 56 has a hook shape extending substantially forward from the main body 20, and the rear attachment piece 57 has a hook shape extending obliquely upward and rearward from the rear edge of the main body 20.

The front transverse wire 24c is bent because it is arranged along the front edge of the main body 20 and so as to avoid the front notch 58. The left and right ends of the front horizontal wire 24c extend forward and extend outward in the left-right direction from the bent portion 51 and along the flange 53, thereby enlarging the support member 8. The front corners of the main body 20 are reinforced without any effort.

The pad 9 (see FIG. 5) is also preferably arranged on the front attachment piece 56 (see FIG. 2) of the support member 8. In this case, since the load of the occupant is applied to the front attachment piece 56 via the pad, the engagement strength of the front attachment piece 56 engaged with the front cross member 15 (see FIG. 2) from above is increased.

As shown in FIGS. 5B and 5C, a hook receiving portion 66 that is recessed upward is formed in a portion of the pad 9 that faces the hook 28. Interference between the pad 9 and the hook 28 can be avoided by the hook receiving portion 66, and the work of attaching the hook 28 to the central locking hole 29 and the side locking hole 30 becomes easy. In order to prevent the hook 28 from falling off, the portion of the pad 9 facing the hook 28 may be pressed against the hook 28 instead of the hook receiving portion 66.

9 is a rear view of the pad 101 in the seat back 3 (see FIG. 1), and FIG. 10 is a perspective view of the side frame 102 of the seat back 3 as viewed from the front inside. Of the skin fixing members 103 for fixing the skin material 10 (see FIG. 1) to improve workability, the one provided on the upper end side of the skin material 10 is higher than the airbag 104 attached to the side frame 102. It is preferable that the attachment position 105 of the other member is separated from the attachment cloth position 106 of the airbag 104 in the vertical and horizontal directions or the front and rear directions.
