Summary of the Invention

Problems to be Solved by the Invention

[0004] Some of the bezels (side belt guides) as described above are fastened to the shoulder of the seat back with bolts. The fastening operation of such a side belt guide is performed, for example, with the seat back placed with the front or rear facing upward. During this fastening operation, after the operator inserts the strap through the side belt guide, it is necessary to pick up the bolt by hand. However, when the operator releases the hand from the side belt guide at that time, the side belt guide falls down, deteriorating the workability.

[0005] An object of the present invention is to obtain a side belt guide capable of improving the workability when fastening with bolts at the shoulder of the seat back and a vehicle seat provided with the side belt guide.

Means for Solving the Problems

[0006] The side belt guide of the first embodiment is a side belt guide fastened with bolts to the shoulder of a seat back, having a locking mechanism that engages with a striker provided on the side of the vehicle body, and the engagement is released by pulling a strap connected to the locking mechanism via a rod, and comprises a base portion having an insertion hole through which the strap is inserted, a belt guide portion extending from the base portion toward the upper side of the seat and engaging with the seat belt, and an anti-tilting portion extending from the base portion toward the inside of the seat back and facing the internal structure of the seat back from the rear side of the seat back in contact with or in close proximity to the internal structure of the seat back.

[0007] In the first embodiment, the seat back to which the side belt guide is bolted to the shoulder has a locking mechanism that engages with a striker provided on the side of the vehicle body, and the engagement is released by pulling a strap connected to the locking mechanism via a rod. In this side belt guide, the strap is inserted through an insertion hole formed in the base, and the belt guide portion extending from the base to the upper side of the seat engages with the seat belt. Furthermore, in this side belt guide, the anti-tilting portion extending from the base into the seat back contacts or is in close proximity to the internal structure of the seat back from the rear side of the seat back. Therefore, when fastening the side belt guide to the shoulder of the seat back is performed, for example, with the seat back facing forward or backward, even if the worker releases their hand from the side belt guide after inserting the strap through the side belt guide, the anti-tilting portion interferes with the internal structure of the seat back, preventing the side belt guide from tipping over. This improves the workability of the fastening operation.

[0008] In the second embodiment of the side belt guide, the anti-tilting portion extends from one side of the base portion in the left-right direction of the seat into the seat back, and within the seat back, a part of the seat back frame is positioned adjacent to the other side of the anti-tilting portion in the left-right direction of the seat.

[0009] In the second embodiment of the side belt guide, since it is configured as described above, for example, when the side belt guide is attached to the left and right shoulders of the seat back and the left and right side belt guides are formed in a symmetrical shape, it is possible to prevent the left and right side belt guides from being mixed up and incorrectly assembled to the seat back. In other words, if the left and right side belt guides are mixed up, the anti-tilting portion extending from one side of the base portion in the left-right direction of the seat, as described above, will interfere with a part of the seat back frame. As a result, it becomes impossible to assemble each side belt guide to the seat back, thus preventing the incorrect assembly of each side belt guide.

[0010] In the third embodiment, the side belt guide, in the first or second embodiment, has a strap guide portion that engages with the strap and restricts the position of the strap.

[0011] In the third embodiment of the side belt guide, the strap guide portion that regulates the position of the strap also serves as the anti-tipping portion, thus simplifying the configuration compared to a configuration in which the strap guide portion and the anti-tipping portion are provided separately.

[0012] A vehicle seat of the fourth embodiment comprises a seat cushion on which a vehicle occupant sits, a seat back that supports the occupant's back and has a locking mechanism that engages with a striker provided on the side of the vehicle body, the engagement of which is released by pulling a strap connected to the locking mechanism via a rod, and a side belt guide of any one of the first to third embodiments fastened to the shoulder of the seat back with bolts.

[0013] In the fourth embodiment of the vehicle seat, the back of the occupant seated on the seat cushion is supported by a seat back. This seat back has a locking mechanism that engages with a striker provided on the side of the vehicle body, and the engagement is released by pulling a strap connected to the locking mechanism via a rod. The side belt guide bolted to the shoulder of this seat back is of any one of the first to third embodiments, and thus the aforementioned effect is obtained. [Effects of the Invention]

[0014] As described above, the present invention makes it possible to improve the workability when bolting the side belt guide to the shoulder area of ​​the seat back. [Brief explanation of the drawing]

Mode for Carrying Out the Invention

[0016] Hereinafter, a vehicle seat 10 according to an embodiment of the present invention will be described with reference to FIGS. 1 to 15. In each figure, some reference numerals may be omitted for the sake of easy viewing of the drawing. Also, the arrows FR, LH, RH, and UP appropriately shown in each figure indicate the front, left, right, and upper directions of the vehicle seat 10, respectively. Hereinafter, when simply explaining using the front-rear, left-right, and up-down directions, it shall indicate the direction with respect to the vehicle seat 10.

[0017] As shown in FIG. 1, the vehicle seat 10 is a three-person split-foldable rear seat, and includes a seat cushion 12 on which a passenger sits, a seat back 14 that supports the back of the passenger, and three headrests 16 that support the heads of the passengers. The seat back 14 is divided into a right seat back 14R for two persons and a left seat back 14L for one person. The right seat back 14R and the left seat back 14L are each rotatably connected to the floor of the vehicle body via a hinge bracket (not shown) and can be folded forward onto the seat cushion 12.

[0018] The left and right seatbacks 14R and 14L are each provided with a locking mechanism 50 (see Figures 2 to 4) for restraining the left and right seatbacks 14R and 14L to the side of the vehicle body (not shown) in the upright position (the position shown in Figure 1; hereinafter referred to as the "upright position"), and a side belt guide 70 (not shown) for guiding the seat belt.

[0019] Each locking mechanism 50 is provided on the left and right outer sides of the left and right seatbacks 14R and 14L. Each locking mechanism 50 is connected to a strap 64 provided on the left and right outer shoulder S of the left and right seatbacks 14R and 14L via a rod 62. Each locking mechanism 50 has a latch (not shown) that engages with a striker (not shown) provided on the side of the vehicle body. This engagement restricts the rotation of the left and right seatbacks 14R and 14L relative to the vehicle body and restrains (locks) them in the upright position. Each side belt guide 70 is attached to the left and right outer shoulder S of the left and right seatbacks 14R and 14L.

[0020] Furthermore, the configurations of the locking mechanism 50 and the side belt guide 70 around the left and right seatbacks 14R and 14L are basically the same except for being symmetrical. Therefore, the configuration of the right seatback 14R will be described below, and the description of the left seatback 14L will be omitted. Also, when describing the front, back, left, right, up, and down directions below, the directions will be those when the seatback 14R is in the upright position.

[0021] The right-side seatback 14R comprises a frame 18 (see Figure 2), which is a structural member; a pad 40 (see Figure 1), which is a cushioning material; and a trim cover 42 (see Figure 1), which is the surface material. The frame 18 is constructed in a frame-like shape by joining together, for example, metal pipes or press-formed metal plates.

[0022] As shown in Figure 2, the frame 18 includes an upper frame portion 20 extending in the left-right direction at the upper end of the seat back 14R, a lower frame portion 22 extending in the left-right direction at the lower end of the seat back 14R, a right side frame portion 24 extending in the up-down direction at the right end of the seat back 14R, a left side frame portion 26 extending in the up-down direction at the left end of the seat back 14R, and an intermediate frame portion 28 extending in the up-down direction at the middle of the seat back 14R in the left-right direction.

[0023] The pad 40 is made of a foam material such as urethane foam and is attached to the frame 18. The pad 40 is roughly rectangular when viewed from the front-to-rear direction of the seat back 14R and is roughly rectangular in shape with the front-to-rear direction of the seat back 14 as the thickness direction. The trim cover 42 is formed into a bag shape by sewing together multiple surface pieces made of, for example, cloth, leather, or synthetic leather, and is placed over the pad 40 from above.

[0024] As shown in Figures 2 to 6, an upper bracket 30 made of press-formed metal plate is fixed to the right end of the upper frame portion 20 of the frame 18. A lock bracket 32 ​​made of press-formed metal plate is fixed to the upper part of the right side frame portion 24.

[0025] The upper bracket 30 is positioned above the upper frame section 20. A wire frame 36, made of bent metal wire, is fixed to the right side of the upper bracket 30. The lock bracket 32 ​​is positioned to the right of the right side frame section 24. A locking mechanism 50 is fixed to the lock bracket 32. The upper bracket 30, lock bracket 32, and wire frame 36 constitute a part of the frame 18.

[0026] The locking mechanism 50 has a housing 54 fixed to the locking bracket 32. The housing 54 is made of a press-formed metal plate and is formed in a roughly box shape with its longitudinal direction in the vertical direction and flattened in the horizontal direction. Two bolts 58 pass through the housing 54, one above and one below. The upper and lower bolts 58 are screwed into two weld nuts 34 fixed to the locking bracket 32. In this way, the housing 54, i.e. the locking mechanism 50, is fastened and fixed to the locking bracket 32, i.e. the frame 18.

[0027] Inside the housing 54 are mechanical components such as a latch (not shown). These mechanical components include a release member 60 (see Figures 3 and 4). The release member 60 is located on the upper front side of the housing 54 and is mounted so as to be displaceable relative to the housing 54. When this release member 60 is operated upward, the engagement between the striker (not shown) located on the right side of the vehicle body and the latch is released. This release releases the restriction on the rotation of the seat back 14R, allowing the seat back 14R to be tilted forward onto the seat cushion 12.

[0028] A rod 62 is connected to the unlocking member 60. The rod 62 is made of a bent metal wire. As shown in Figures 3 to 6, the rod 62 is made up of a first longitudinal extension 62A extending upward from the unlocking member 60, a first transverse extension 62B extending to the left (inward in the sheet width direction) from the upper end of the first longitudinal extension 62A, a second longitudinal extension 62C extending upward from the left end of the first transverse extension 62B, a second transverse extension 62D extending to the left from the upper end of the second longitudinal extension 62C, and a guide engaging portion 62E extending diagonally downward and rearward from the left end of the second transverse extension 62D.

[0029] The first longitudinal extension 62A constitutes the base end of the rod 62, the first transverse extension 62B, the second longitudinal extension 62C, and the second transverse extension 62D constitute the middle section of the rod 62, and the guide engagement portion 62E constitutes the tip of the rod 62. The lower end of the strap 64 is connected to the second transverse extension 62D.

[0030] The strap 64 is made of a long, strip-shaped material, such as a synthetic fiber, and is flexible. The strap 64 is inserted through an insertion hole 80 formed in the side belt guide 70. As shown in Figure 5, the side belt guide 70 is made of a main body 72 and a strap guide 84. The main body 72 is made of a resin molded product with metal parts insert-molded into it, and integrally has a base 74 fixed to the upper bracket 30 and a belt guide 76 extending upward from the base 74 towards the seat.

[0031] The base portion 74 is roughly plate-shaped with its thickness in the vertical direction and is superimposed on the upper surface of the upper bracket 30. This base portion 74 is fixed to the upper bracket 30 by means of bolt fastening or the like. The belt guide portion 76 extends outward from the front of the base portion 74 in the left-right direction from the upward side and is roughly plate-shaped with its thickness in the front-rear direction. This side belt guide 70 is positioned towards the left-right outer side at the front of the base portion 74. A slit 78 is formed in this belt guide portion 76 through which a seat belt (not shown) is inserted.

[0032] An insertion hole 80 is formed in the left-right inner portion of the front part of the base portion 74, penetrating the base portion 74 in the vertical direction. The insertion hole 80 has an oval shape with the left-right direction as its longitudinal side when viewed from the vertical direction. A strap 64 is inserted through this insertion hole 80 along the vertical direction. The lower part of this strap 64 is located inside the seat back 14R.

[0033] As shown in Figure 6, a cylindrical projection 82 protrudes downward from the edge of the insertion hole 80 on the lower surface of the base portion 74. The cylindrical projection 82, like the insertion hole 80, has an oval shape with its length in the left-right direction when viewed from above. The inside of the cylindrical projection 82 is in communication with the inside of the insertion hole 80, and the strap 64 is inserted through the cylindrical projection 82. A strap guide portion 84 is attached to this cylindrical projection 82.

[0034] The strap guide portion 84 is made of, for example, injection-molded resin and has an elongated shape with its length in the vertical direction. This strap guide portion 84 corresponds to the "anti-tipping portion" in the present invention. As shown in Figures 7 to 10, the upper part of the strap guide portion 84 is a cylindrical portion 86. The cylindrical portion 86 has an oval shape with its length in the left-right direction when viewed from the vertical direction. The upper part 86A of the cylindrical portion 86 is formed to be larger in the left-right and front-back directions than the lower part 86B of the cylindrical portion 86.

[0035] The cylindrical projection 82 of the base portion 74 is fitted inside the upper part 86A of the cylindrical portion 86. A locking claw 88 formed on the front surface of the cylindrical projection 82 is fitted into a locking hole 90 formed on the front surface of the cylindrical portion 86. This prevents the cylindrical portion 86 from falling off the cylindrical projection 82, and the strap guide portion 84 is fixed to the base portion 74. The strap guide portion 84 extends into the seat back 14R from the lower surface of the left side portion (one side in the left-right direction) of the base portion 74. Inside the seat back 14R, a wire frame 36, which is part of the frame 18 of the seat back 14R, is positioned adjacent to the right side of the strap guide portion 84 (the other side in the left-right direction of the seat). The wire frame 36 is positioned below the right side portion of the base portion 74.

[0036] A guide piece 92 extends downward from the rear of the lower part 86B of the cylindrical portion 86. The guide piece 92 is a roughly elongated plate shape with its longitudinal direction in the vertical direction and its thickness direction in the front-to-back direction. Both ends of the guide piece 92 in the left-right direction are made up of embankment portions 92A, and the middle part of the guide piece 92 in the left-right direction is made up of a recess 92B that is recessed further rearward than the left and right embankment portions 92A. The lower end of the guide piece 92 is formed in a shape that is pointed downward when viewed from the front-to-back direction.

[0037] The lower part of the strap 64, which is inserted into the cylindrical projection 82 of the base portion 74, is also inserted into the cylindrical portion 86. The lower end of the strap 64 is positioned below the cylindrical portion 86 and in front of the guide piece 92, and is inserted into the recess 92B of the guide piece 92. The second lateral extension 62D of the rod 62 is positioned in front of the guide piece 92.

[0038] The lower end of the strap 64 is wrapped around the second transverse extension 62D of the rod 62, and the portions before and after the wrapping are sewn together. In this way, the lower end of the strap 64 is connected to the second transverse extension 62D of the rod 62, and the strap 64 and the release member 60 are connected via the rod 62. When the strap 64 is pulled upward by the occupant, the rod 62 and the release member 60 are displaced upward, and the engagement between the latch and the striker is released.

[0039] As shown in Figure 4, the guide engagement portion 62E of the rod 62 engages (in this case, contacts) with the guide piece 92 from the left side (inward in the left-right direction). When the strap 64 is pulled upward, the guide engagement portion 62E slides against the left edge of the guide piece 92. This configuration restricts the displacement direction of the rod 62 to the vertical direction.

[0040] Furthermore, the lower end of the strap 64 is positioned within the recess 92B of the guide piece 92 by the rod 62. The width dimension of the recess 92B in the left-right direction is formed to be slightly larger than the width dimension of the strap 64 in the left-right direction. The left-right displacement of the strap 64 is limited by the lower end interfering with (contacting) the left and right bank portions 92A of the guide piece 92. In addition, the front-rear displacement of the strap 64 is limited by the lower end, which is wrapped around the second transverse extension 62D of the rod 62, contacting the guide piece 92 from the front.

[0041] The fastening of the side belt guide 70 to the seat back 14R in the above configuration is performed with the seat back 14R positioned with its front or rear (in this case, rear) facing upwards, as shown in Figures 11 to 13. During this fastening process, first, as shown in Figures 11 to 12, the strap 64 is inserted through the insertion hole 80 of the side belt guide 70. Then, as shown in Figure 13, the side belt guide 70 is fastened to the shoulder portion S of the seat back 14R with one or more (in this case, two) bolts 94. Each of these bolts 94 is screwed into a weld nut (not shown) fixed to the upper bracket 30.

[0042] As shown in Figures 12 and 13, when the base portion 74 of the side belt guide 70 is in contact with the shoulder portion S of the seat back 14R, as shown in Figure 14, the strap guide portion 84 of the side belt guide 70 contacts or is in close proximity to (in this case, in contact with) the second transverse extension portion 62D of the rod 62 from the rear side of the seat back 14R. This is configured to hold the side belt guide 70 in the position shown in Figures 12 and 13 before bolt fastening (i.e., it is configured to prevent the side belt guide 70 from falling in the direction indicated by arrow F in Figure 13). The rod 62 corresponds to the "internal structure of the seat back" in this invention.

[0043] In the vehicle seat 10 with the above configuration, the back of the occupant seated on the seat cushion 12 is supported by the seat back 14R. This seat back 14R is rotatably connected to the vehicle body. A locking mechanism 50 is provided on the side of the seat back 14R. When this locking mechanism 50 engages with a striker provided on the side of the vehicle body, the rotation of the seat back 14R is restricted. A strap 64 is connected to the locking mechanism 50 via a rod 62. By pulling this strap 64, the engagement is released, and the seat back 14R can be tilted forward.

[0044] In the side belt guide 70 attached to the shoulder S of the seat back 14R, the strap 64 is inserted through an insertion hole 80 formed in the base portion 74, and the seat belt (not shown) engages with the belt guide portion 76 extending upward from the base portion 74. Furthermore, in this side belt guide 70, the strap guide portion 84 extending from the base portion 74 into the seat back 14R contacts the rod 62 from the rear side of the seat back 14R. Therefore, when fastening the side belt guide 70 to the shoulder S of the seat back 14R, even if the worker releases their hand from the side belt guide 70 after inserting the strap 64 through the insertion hole 80, the strap guide portion 84 interferes with the rod 62, preventing the side belt guide 70 from tipping over (see arrow F in Figure 13). This improves the workability of the fastening operation.

[0045] Furthermore, the strap guide portion 84 extends from the left side of the base portion 74 (one side in the left-right direction of the seat) into the seat back 14R, and within the seat back 14R, a wire frame 36, which is part of the frame 18 of the seat back 14R, is positioned adjacent to the right side of the strap guide portion 84 (the other side in the left-right direction of the seat). With this configuration, as in this embodiment, when the side belt guides 70 are attached to the left and right shoulders S of the seat back 14, and the left and right side belt guides 70 are formed in a symmetrical shape, it is possible to prevent the left and right side belt guides 70 from being mixed up and assembled to the seat back 14. As a result, the work of reassembling the incorrectly assembled side belt guides 70 is eliminated, and the productivity of the vehicle seat 10 is improved.

[0046] In other words, for example, as shown in Figure 15, if the left side belt guide 70 is mistakenly installed on the shoulder joint S of the right seat back 14R, the strap guide portion 84 of the left side belt guide 70 will interfere with the wire frame 36, making it impossible to install the side belt guide 70. The same applies if the left side belt guide 70 is mistakenly installed on the shoulder joint S of the right seat back 14R, although this is not shown in the figure. As a result, incorrect installation of the left and right side belt guides 70 can be prevented.

[0047] Furthermore, in this embodiment, the position of the strap 64 is restricted by the strap guide portion 84. Specifically, the strap guide portion 84 contacts the guide engagement portion 62E of the rod 62 from the left side, thereby suppressing lateral play of the rod 62. This prevents the position of the strap 64 from fluctuating due to play in the rod 62. Also, for example, it is possible to prevent the rod 62 from tilting due to interference between the seat back 14R pad 40 and the rod 62, thus preventing the position of the strap 64 from fluctuating due to the tilt of the rod 62.

[0048] Furthermore, in this embodiment, the left and right bank portions 92A provided on the guide piece 92 of the strap guide portion 84 interfere with the strap 64 from both sides in the left-right direction. This suppresses the tilt of the strap 64 in the left-right direction, thereby suppressing variations in the position of the strap 64 due to the tilt of the strap 64 in the left-right direction. In addition, in this embodiment, the guide piece 92 of the strap guide portion 84 contacts the portion of the strap 64 that wraps around the rod 62 from the rear side, thereby suppressing the tilt of the strap 64 in the front-rear direction. This suppresses variations in the position of the strap 64 due to the tilt of the strap 64 in the front-rear direction.

[0049] Furthermore, since the strap guide section 84 that regulates the position of the strap 64, as described above, also serves as an anti-tipping section that prevents the side belt guide 70 from tipping over before fastening, the configuration can be simplified compared to a configuration in which the anti-tipping section and the strap guide section 84 are provided separately.

[0050] In the above embodiment, the strap guide portion 84 is configured as an anti-tipping portion, but the configuration is not limited to this. Alternatively, the anti-tipping portion may be provided on the side belt guide 70 separately from the strap guide portion 84, or the side belt guide 70 may not have a strap guide portion 84 and only have an anti-tipping portion.

[0051] Furthermore, in the above embodiment, the rod 62 is configured as the "internal structure of the seat back" according to the present invention, but this is not the only configuration. For example, a part of the frame of the seat back or a part of the pad may be configured as the "internal structure of the seat back" according to the present invention.

[0052] Furthermore, in the above embodiment, the strap guide portion 84 is configured to engage with the rod 62 from the right side, but the configuration is not limited to this, and the strap guide portion 84 may be configured to engage with the rod 62 from the left side or from both sides in the left and right directions. Alternatively, the strap guide portion 84 may be configured not to engage with the rod 62.

[0053] Furthermore, in the above embodiment, the strap guide portion 84 is configured to engage with the strap 64 from both sides in the left-right direction, but the configuration is not limited to this, and the strap guide portion 84 only needs to engage with the strap 64 from at least one side in the left-right direction. Also, in the above embodiment, the strap guide portion 84 is configured to engage with the strap 64 from the rear side, but the configuration is not limited to this, and the strap guide portion 84 only needs to engage with the strap 64 from at least one side in the front-rear direction.

[0054] Furthermore, the present invention can be implemented with various modifications without departing from its spirit. Of course, the scope of the present invention is not limited to the embodiments described above. [Explanation of symbols]
