Description

[Technical field]

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

[0002] A seat pad made of foam is used as a seat cushion for a vehicle seat. The seat pad is equipped with a seat cover, or has an elastically deformable insert wire inserted inside. These seat pads and inflatable cushions are used (see, for example, Patent Document 1). The manner in which the occupant is supported by the sart wires etc. affects the seating comfort and posture stability. For example, the balance of pressure in the front-rear direction on the lower body of the occupant is appropriate, and the occupant's bones are supported. If the board can be kept upright, the seating comfort and posture stability will be improved. If this is not the case, the seating comfort and posture stability will inevitably deteriorate.

[0003] Specifically, the following cases may have a negative effect on seating comfort and posture stability. For example, if the seat pad is soft, the buttocks will not fit in and the pelvis will not drop (collectively referred to in this specification). The hips drop (called "hip drop") becomes larger, and the pelvis rotates or tilts backward, resulting in a bad posture. In addition, if the buttocks shift forward due to poor posture, etc., In writing, this is called "front slippage" of the buttocks, and it feels as if the flesh and bones of the buttocks are being pulled away, and sometimes there is a numbness. This creates a sensation that is similar to the sensation of shearing (referred to as a "shear sensation" in this specification). The breakage phenomenon tends to be more noticeable when it is accompanied by tail drop.

[0004] The above-mentioned phenomena and sensations such as "tail drop", "front slippage" and "shearing sensation" are the cause of low ratings. One of the conventional methods to improve the value is to increase the hardness of the urethane seat pad. The aim of the study was to improve these issues by [Prior art documents] [Patent documents]

[0005] [Patent Document 1] JP 2012-091544 A Summary of the Invention [Problem to be solved by the invention]

[0006] However, simply increasing the hardness of the seat pad will not improve the seating comfort and posture stability. There is a limit to how much sex can be increased.

[0007] Therefore, the present invention aims to improve the seating comfort and seating comfort by a method other than increasing the hardness of the seat pad. The object of the present invention is to provide a vehicle seat that can improve posture stability. do. [Means for solving the problem]

[0008] In order to solve this problem, the present inventors have developed a seat cushion 20' Focusing on the insert wires 40' and 50', various studies were carried out (see FIG. 16, etc.). If so, in order to prioritize seating comfort, inserts should be placed directly under the passenger's hips and pelvis. It is generally best to avoid a layout in which the wires 40' and 50' come into contact with each other. (See Figs. 16 and 17.) In addition, the front hanging part formed on the seat pad 21' The seat cover is attached to the groove 71' and the rear hanging groove 72' by engaging the hanging portion of the seat cover. If the vehicle seat is equipped with a hanging structure for hanging and supporting the seat cover, The insert wire 40' is located forward of the front hanging groove 71', and the rear insert wire 50' is located forward of the front hanging groove 71'. In general, the rear end of the rear hanging groove 72' is disposed behind the rear hanging groove 72' (see FIG. 18). The inventors have fundamentally reconsidered these conventional general ideas and technical common sense, As a result of repeated consideration without being bound by the concept, we were able to obtain new knowledge that would lead to the solution of the problem. I did.

[0009] One aspect of the present invention that has been conceived based on such findings is a vehicle seat, A seat pad and a front insert wire and a seat provided in the seat pad The seat is provided in the seat pad and is located rearward in the front-rear direction of the vehicle seat from the front insert wire. a seat including a rear insert wire attached to the seat; A backrest that can be reclined around a pivot point; The seat cover is suspended in the front and rear suspension grooves formed in the seat pad. a hanging structure for hanging and supporting the seat cover by engaging the seat cover with the seat cover; Equipped with The front insert wire, which is bent at multiple bends, is located behind the surrounding area. A front main load receiving portion having a protruding shape is provided. The rear insert wire, which is bent at multiple bends, is located forward of the surrounding area. A protruding rear main load receiver is provided. The rear insert wire is designed so that at least the rear main load receiver is forward of the rear hanging groove. It is placed in a position where The front insert wire is designed so that at least the front main load receiving part is behind the front hanging groove. It is located in a position A vehicle seat.

[0010] In such a vehicle seat, the rear main load receiving portion of the rear insert wire is within a predetermined range. The rear main load receiver and the front main load receiver of the front insert wire are located within the enclosure. By keeping the separation distance within a specified range, the front main load receiver and the rear main load receiver This makes it possible to effectively support the pelvis, particularly the area around the ischial bones, of the occupant. Even without making the seat pad harder, it suppresses the phenomenon and sensation of the occupant's hips dropping, shifting forward, and shearing. In addition to preventing shear stress and improving seating comfort, By softening the padding, it is possible to improve the feeling of comfort. It is.

[0011] In the vehicle seat as described above, at least the front main load receiving portion and the rear main load receiving portion The other one may be configured with a straight portion extending in the left-right direction of the vehicle seat.

[0012] In the vehicle seat as described above, at least the front main load receiving portion and the rear main load receiving portion The other is formed symmetrically about the center line in the left-right direction of the vehicle seat. Good too.

[0013] In the above vehicle seat, the front insert wire is In plan view, the recess may be inclined downward toward the rear.

[0014] The rear insert wire in the vehicle seat as described above is attached to the side of the vehicle seat. When viewed from the periphery of the rear main load receiver toward the rear main load receiver, The plate may be provided so as to be inclined downward along the axis of the plate.

[0015] In the vehicle seat as described above, the rear main load receiving portion is disposed in the middle of the rear insert wire. It may be located at the lowest point.

[0016] In the vehicle seat described above, the length of the front main load receiving portion in the left-right direction is It may be longer than the length of the weight receiving portion in the left-right direction.

[0024] Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings (see FIG. 1, etc.). ).

[0025] In the following, the side of the vehicle seat 10 to which the occupant faces (usually the direction of travel of the vehicle) will be referred to as the side of the vehicle seat 10 to which the occupant faces. The front side of the vehicle seat 10 is designated by the symbol F in some drawings. This refers to the rear, left and right direction (or width direction) based on this.

[0026] The vehicle seat 10 according to the present invention comprises a seat cushion (seat) 20 and a seat back ( The seat back 30 is a reclining seat that rotates around a pivot point 31. Inning operation is possible (see Figure 3, etc.). Note that Figure 3, etc. shows the internal structure, especially In order to clearly show the front insert wire 40 and the rear insert wire 50 described later, Hatching is omitted.

[0027] The seat cushion 20 is provided with a seat pad 21 made of foam. The vehicle seat 10 of this embodiment has a front hanging groove 71 formed in the seat pad 21 and After that, the hanging portions 22a, 22b of the seat cover 22 are engaged with the hanging grooves 72. A hanging structure 70 for hanging and supporting the seat cover 22 is provided (see FIG. 3, etc.). The front hanging groove 71 and the rear hanging groove 72 extend in the left-right direction. Of the three areas of the seat cushion 20 that are divided, the front one is Area 1, the middle one is Area 2, For the sake of convenience, the area in front will be referred to as area 2, and the area behind as area 3 in this specification (see FIG. 16). reference).

[0028] The seat pad 21 includes an elastically deformable insert for supporting the load of the occupant. In the vehicle seat 10 of this embodiment, an insert wire is provided. As the insert wire, the front insert wire 40, the rear insert wire 50, and the right outer wire A wire 61, a left outer wire 62, a right inner wire 63, and a left inner wire 64 are provided. (See FIG. 2, etc.) The right outer wire 61 is disposed on the right outer side of the seat pad 21, and the left outer wire 62 is disposed on the left outer side of the seat pad 21. The seat pad 21 is provided on the left outer side thereof with a center line 11 extending in the left-right direction from the front to the rear of the vehicle seat 10. The right inner wire 63 is arranged symmetrically with respect to the seat 0C (see FIG. 1, etc.). The left inner wire 64 is located inside the right outer wire 61 of the area 1 of the pad 21. The pad 21 is located on the left side of the area 1 of the pad 21, and is located on the inside of the outer wire 62. ... They are arranged symmetrically (see Figure 1, etc.).

[0029] [Front and rear insert wires] The front insert wire 40 is located near the boundary between area 1 and area 2 in this embodiment. In this case, most of the swarm is located in Area 2, and extends to the left and right (Figure 1 (See FIG. 3, etc.) The front insert wire 40 is bent at a plurality of bent portions 42 and Between the bent portions 42, a front straight portion 41 is provided at one position on each side. The front straight portion 41 is a part of the front straight portion 42. The front straight portion 41 protrudes rearward from the peripheral portion (indicated by reference numeral 48 in FIG. 7). In this embodiment, the periphery of the front straight portion 41 is The portion 48 protrudes rearward beyond the portion supported by the hanging structure 70. The area around the front straight 41 is where most of the weight of the occupants is carried. It functions as a front main load receiving portion that receives the load (see FIG. 7, etc.). The portion conveniently called the straight portion 41 is the portion that functions as the front main load receiving portion. This is just one example of a good example. Even if the shape is different, it will still function as the front main load receiver as described below. It is sufficient if it can be achieved. In this respect, being straight is a good example, but It can be said that the present invention is not limited to the above.

[0030] The rear insert wire 50 is located near the boundary between area 2 and area 3 in this embodiment. In this case, most of the swarm is located in Area 2, and extends to the left and right (Figure 1 (See FIG. 3, etc.) The rear insert wire 50 is bent at a plurality of bent portions 52 and Between the bent portions 52, there are two rear straight portions 51 extending left and right. The rear straight portion 51 has a bilaterally symmetrical shape having two in total (see FIG. 6). The rear straight portion 51 is projected forward from the peripheral portion (indicated by reference numeral 58 in FIG. 7). In this embodiment, the portion around the rear straight portion 51 is The portion 58 is so arranged as to protrude forward from the portion supported by the hanging structure 70. The area around the rear straight 51 is where most of the passenger weight is carried. In this embodiment, the rear thrust plate functions as a rear main load receiving portion (see FIG. 7, etc.). The portion conveniently called the straight portion 51 is a portion that functions as a rear main load receiving portion. This is just one example. For example, it is not straight, but has a gentle curve. Regardless of the shape, it will still function equally as the rear main load receiver as described below. In this respect, being straight is a good example, but It can be said that there is no limit.

[0031] The rear insert wire 50 extends from the pivot fulcrum 31 of the seat back 30 to the rear stretcher. The distance L1 to the port portion 51 is a predetermined length (see FIG. 3). is 155 mm or more, preferably 170 mm or more.

[0032] The front insert wire 40 is disposed between the rear straight portion 51 and the front straight portion 41. The distance L2 is preferably set to a predetermined length (see FIG. 3). 0mm or more and 70mm or less.

[0033] In the vehicle seat 10, the front insert wire 40 is inserted through the front hanging groove 71. The rear insert wire 50 is located further rearward than the rear hanging groove 72. In some cases, the structure may be as follows (see Figure 3, Figure 4A, etc.).

[0034] In the vehicle seat 10 as described above, the rear seat 11 is disposed at a predetermined position or within a predetermined range. The rear straight portion 51 of the insert wire 50 and the front straight portion of the front insert wire 40 The straight portion 41 effectively supports the pelvis H2 of the occupant's buttocks H1, especially the area around the ischium H3. As a result, the seat belt can be effectively supported (see Figs. 4A and 8). Even without making the seat cushion harder, it suppresses the phenomenon and sensation of passengers dropping their hips, shifting forward, and feeling of shear. In this respect, up until now, vehicle seats have placed emphasis on comfort. The insert wires are so loose that they come into contact with the passenger's hips (H1) or just below the pelvis (H2). Such a layout should be avoided (or, in other words, taboo). Normally, the insert wire is placed in area 1 or area 3, avoiding area 2. In this embodiment, the conventional layout is different. From the viewpoint of the above, in other words, the seating comfort performance and From the viewpoint of improving the posture stability, the rear straight section 5, which can be the main load receiving section, 1 and the front straight portion 41. Even if the configuration were to be within the range of the rear 2, it would be something like a taboo if you look at it from another perspective. The insertion wire is placed in area 2, which is a step beyond conventional wisdom. By taking advantage of a technique that had not been used in the past, we were able to realize functions that could not be realized with the previous structure. In addition, comparing the state where the tail is dropped and the state where it is not dropped, In this case, the former may have a stronger shearing sensation. The rear insert wire 50, especially the rear straight portion 51, prevents the occupant's lower body from dropping. The pelvis of the occupant is raised by optimizing the balance of pressure on the body in the front-rear direction (Good state) ) (see FIG. 19). In addition, the front insert wire 40 and the rear insert wire 50 From the viewpoint of improving seating comfort, the above-mentioned configuration allows for uniform deflection. This also helps to soften the pads (which allows them to become softer).

[0035] Based on the above viewpoint, in this embodiment, the vehicle seat 10 is further configured as follows. These will be explained in order (see Figure 3, etc.).

[0036] [Suspended structure] An example of a hanging structure 70 is shown. The hanging structure 70 of this embodiment is a seat cover 22 The suspended portion 22a (22b) is connected to the insert wire (the front insert wire 40, the rear A hanging member 74 and a hog ring (C-ring) 76 for hanging on the insert wire 50 are provided. The suspending member 74 has one end that is suspendable from the seat cover 22 (see FIG. 4B). The other end of the hanging member 74 is fixed to the hanging portion 22a (22b) by sewing or the like. The resin portion 74r of the hanging member 74 and the insert wire are The seat cover 22 is fixed to the seat cushion 2 by the hog ring 76. The slit 71 is hung in the front slit 71 (or the rear slit 72) of the slit 0 (see FIG. 4B). Although not shown in the figure, other insert wires (in the present embodiment , right outer wire 61, left outer wire 62, right inner wire 63, left inner wire 64 The hanging structures in the above are similarly configured. The positions and the number of these hanging structures 70 are is not particularly limited. As an example, in the vehicle seat 10 of the present embodiment, 1, a hanging structure 70 is provided at each of the locations indicated by circles (◯) in FIG.

[0037] [Side view of the front and rear insert wires] In the vehicle seat 10 of this embodiment, the front insert wire 40 is 10, when viewed from the side, is provided in a state in which it is inclined downward toward the rear. In addition, the rear insert wire 50 is From the peripheral portion 58 of the rear straight portion 51 toward the rear straight portion 51, The slope is set so that it slopes downwards as it approaches the ceiling (see Figure 3). The front insert wire 40 and the rear insert wire 50 are arranged so that they are spaced apart from each other as viewed downward. By arranging the seats in a narrow shape (so to speak, an inverted V shape) so that they are close to each other, When seated, the buttocks H1 can be guided to a more appropriate seating point, preventing forward slippage. This helps to improve the comfort of sitting. The side insert wire 50 supports the occupant seated in a predetermined seating position from the front and rear. The rear straight portion 51 is also useful in that it allows the user to maintain a stable posture. It may be located at the lowest point of the rear insert wire 50 (see FIG. 4A, etc.).

[0038] [Left and right length of front and rear straight sections] In the vehicle seat 10 of this embodiment, the length of the front straight portion 41 in the left-right direction is , is longer than the length of the rear straight portion 51 in the left-right direction (see FIG. 7, especially the dashed line in the drawing). Such a front insert wire 40 is attached to the front of the pelvis H2 of the occupant to the thigh. The seat is located near the base of the seat, and when the occupant's hips H1 move forward or experience a shearing sensation, When the baby is about to be born, the relatively wide front straight portion 41 provides stable support. (See Figure 8, etc.)

[0039] [Front and rear position of the front and rear straight sections] In the vehicle seat 10 of this embodiment, a front seat belt 14 is provided in front of the rear straight portion 51. These front insert wires 40 are arranged so that at least a part of the front straight portion 41 is positioned. and the rear insert wire 50 are arranged (see FIG. 9, etc.). The insert wire 40 and the rear insert wire 50 overlap each other in the width direction. This means that an area where the By ensuring as much overlapping area as possible, it is possible to increase the stability of occupant support. In addition, the front straight, which is the part that receives most of the body pressure of the occupant's pelvis H2, By overlapping the rear straight portion 41 and the rear straight portion 51 in this manner, the seating comfort is improved. It is possible.

[0040] [Number of Bends] The number of bends 42 in the front insert wire 40 and the number of bends 52 in the rear insert wire 50 Although the numbers are not particularly limited, in this embodiment, as an example, these numbers In other words, the number of bending points is the same for both sides (see Figure 10A). In this specification, the bent portion of the insert wire is called a "bent portion". " and the relevant part is indicated by a dotted circle in Figure 10A (see Figure 10A). In addition, the part indicated by the dashed oval in Figure 10B can be interpreted as the "bending part" or It is also possible to interpret the other part indicated by the dashed oval in C as the "bend" ( (See Figs. 10B and 10C). However, regardless of which interpretation is used, in this embodiment, The number of bent portions 42 of the insert wire 40 is equal to the number of bent portions 52 of the rear insert wire 50. It is as follows.

[0041] [Bending part] The bending angle at the bent portions 42 and 52 may be an obtuse angle. A part of the bent portion 52 of the insert wire 50 is bent at an obtuse angle, and the part extending from the center to the side is bent at an obtuse angle. The part is gently bent or curved, like an S-shape (see Figure 11, etc.). By making the rear insert wire 50 in this shape, the feeling of bending is made uniform and the body pressure is It is effective in equalizing the balance.

[0042] [Shape of the insert wire near the end] The terminals of the front insert wire 40 and the rear insert wire 50 (outer right The shapes of the wire 61 and the portions 44 and 54 near the left outer wire 62 are also not particularly limited. Instead, as another example of the shape shown so far, a bend is added to the terminal portions 44, 54. In such a case, for example, the foam type of the pad ( The front insert wire 40 and the rear insert wire 50 are set in the At that time, the terminal portions 44, 54 are fitted to a backing plate (not shown) or the like protruding inward in the foaming mold. By doing so, the front straight portion 41 and the rear straight portion 51 can be positioned as desired. It becomes possible to control or manage the position, depth, and angle of the water.

[0043] [If installing a heater / air conditioning mat] A vehicle seat 10 is equipped with a mat 90 that is integrated with a heater (not shown) or is air-conditioned When doing so, please take note of the following points when selecting the front insert wire 40 and the rear insert wire 50. (See FIG. 13.) First, the hanging member 74 provided on the seat cover 22 and The air conditioning mat 90 is sandwiched between the insert wire (such as the front insert wire 40) and the Doing so may result in heater disconnection, so do not insert the front insert wires 40 into these positions. Also, the front of the front hanging groove 71 is not placed in the front insert wire 50. The position P3 on the side of the seat and the position P4 behind the rear hanging groove 72 are the same as those described above. From the viewpoint of improving performance and posture stability, the front insert wire 40 and the like are provided at these positions. The rear insert wire 50 is also not arranged. When a recess 21s for providing the mat 90 is formed, the seat pad 21 The greater the thickness, the stronger the force that supports a person (the force that pushes back a person). If there is a rear end 91 of the air conditioning mat 90, the seat pad 21 will be thinner. The seat pad 21 is placed under the air conditioning mat 90 (not in the thick part of the seat pad 21). By placing insert wires in the areas where the thickness of the mat is thin, the air conditioning mat can be used for 90 minutes. The support force of the pad thickness can be supplemented by insert wires.

[0044] [Total width of insert wire] The overall width of the rear insert wire 50 is adjusted to match the styling design of the vehicle seat 10. (Length in the left-right direction) W50 should be narrower than the overall width W40 of the front insert wire 40. It can be set as follows (see FIG. 14).

[0045] [Relationship with air-conditioning mats] Among the air vents 92 of the air conditioning mat 90, those located below the buttocks H1 of the occupant are as shown in FIG. It may be placed inside the dashed rectangle in the figure (see Figure 15). If the seat is in the previous position (see Figures 16 to 18), the pelvis H2 of the passenger will drop (buttocks will drop). The size is relatively large, causing a sense of forward shift and shear, and the ventilation holes 92 are positioned exactly as intended. There was a possibility that the seating position would be misaligned with the actual seating position. The vehicle seat 10 stabilizes the seating position while improving seating comfort. Therefore, the air conditioning function expected of the vent hole 92 of the air conditioning mat 90 can be achieved. do.
