[0003] [Patent Document 1] Japanese Utility Model Application Publication No. 1-145870 Summary of the Invention [Problem to be solved by the invention]

[0004] In the above-mentioned prior art, the connecting member to which the leading end of the seat belt is fastened rotates around the bolt relative to the anchor member in the fore-and-aft direction of the seat, which causes variations in the position at which the seat belt restrains the occupant's waist in the fore-and-aft direction of the seat, which may result in variations in the timing at which the seat belt restrains the occupant's waist in the event of a vehicle collision.

[0005] In consideration of the above, the present invention aims to provide a seat belt anchor member and a vehicle seat that can suppress variation in the position where the seat belt is placed on the occupant's waist in the fore-and-aft direction of the seat. [Means for solving the problem]

[0006] The anchor member of the seat belt of the first embodiment comprises a locking plate that is locked to the upper rail of the seat slide rail, and a movable plate that is rotatably connected to the locking plate around an axis along the fore-and-aft direction of the seat and to which the tip of the seat belt is locked.

[0007] According to the seat belt anchor member of the first aspect, the locking plate is locked to the upper rail of the seat slide rail, and the leading end of the seat belt is locked to the movable plate. The movable plate is connected to the locking plate so as to be rotatable about an axis along the front-rear direction of the seat. This makes it possible to suppress variation in the position where the seat belt is hooked around the occupant's waist in the front-rear direction of the seat, compared to a conventional anchor member that rotates about an axis along the left-right direction of the seat.

[0008] In the seatbelt anchor member of the second aspect, in the first aspect, at least one of the locking plate and the movable plate has a limiting portion that limits the rotation range of the movable plate relative to the locking plate.

[0009] According to the seat belt anchor member of the second aspect, the limiting portion provided on at least one of the locking plate and the movable plate limits the range of rotation of the movable plate relative to the locking plate, thereby improving workability when, for example, attaching a cover that covers the anchor member to the vehicle seat.

[0010] The seat belt anchor member of the third aspect is the same as that of the first aspect, and further includes a biasing member that biases the movable plate in an upright direction relative to the locking plate.

[0011] According to the seat belt anchor member of the third aspect, the movable plate is biased in the upright direction relative to the locking plate by the biasing member, which improves workability when, for example, attaching a cover that covers the anchor member to the vehicle seat.

[0012] The seat belt anchor member of the fourth aspect is any one of the first to third aspects, in which a rivet is fixed to the upper rail, and the locking plate is formed with an oval hole having a large diameter portion through which the head of the rivet is inserted and a small diameter portion through which the head is caught on an edge portion.

[0013] According to the seat belt anchor member of the fourth aspect, the head of the rivet fixed to the upper rail is inserted into the large-diameter portion of the pothole formed in the locking plate and hooked onto the edge of the small-diameter portion of the pothole, thereby allowing the locking plate to be locked to the upper rail without the need for tools.

[0014] A seatbelt anchor member of a fifth aspect is the fourth aspect, wherein the locking plate has a restricting portion that restricts relative movement of the rivet from the small diameter portion side to the large diameter portion side.

[0015] According to the seat belt anchor member of the fifth aspect, the restricting portion provided on the locking plate restricts the relative movement of the rivet from the small diameter portion side to the large diameter portion side of the pothole, thereby preventing the locking plate from accidentally coming off the rivet.

[0016] The seatbelt anchor member of a sixth aspect is the fourth or fifth aspect, wherein the head portion of the rivet and the large diameter portion are formed in a keyhole shape.

[0017] According to the seat belt anchor member of the sixth aspect, the head of the rivet, which is formed in a keyhole shape, is inserted into the large-diameter portion of the keyhole-shaped slot in the locking plate, which makes it possible to prevent, for example, incorrect assembly of the locking plate to the upper rail.

[0018] A vehicle seat of a seventh aspect includes a seat cushion on which a vehicle occupant sits, a seat back that supports the back of the occupant, a seat slide rail that slidably connects the seat cushion to the floor of the vehicle body, and a seat belt anchor member of any one of the first to sixth aspects, in which the locking plate is locked to the upper rail of the seat slide rail.

[0019] According to the vehicle seat of the seventh aspect, a vehicle occupant sits on a seat cushion, and the occupant's back is supported by the seat back. The seat cushion is slidably connected to the floor of the vehicle body by a seat slide rail. A locking plate provided on an anchor member of a seat belt is locked to the upper rail of the seat slide rail. This anchor member is one of the first to sixth aspects, and therefore the above-mentioned functions and effects can be obtained. [Effects of the Invention]

[0020] As described above, the seatbelt anchor member and vehicle seat according to the present invention can suppress variations in the position where the seatbelt rests on the occupant's waist in the front-rear direction of the seat. [Brief explanation of the drawings]

[0022] A vehicle seat 10 according to one embodiment of the present invention will be described below with reference to Figures 1 to 9. Note that in each figure, some reference numerals may be omitted to make the drawings easier to understand. Arrows FR, LH, RH, and UP, which are appropriately depicted in each figure, respectively indicate the front, left, right, and top of the vehicle seat 10. Hereinafter, when the front-rear, left-right, top-bottom directions are used in the description, they will indicate directions relative to the vehicle seat 10 unless otherwise specified.

[0023] 1, a vehicle seat 10 according to this embodiment includes a seat cushion 12 on which a vehicle occupant sits, a seat back 18 that supports the occupant's back, and a seat slide rail 20 that slidably connects the seat cushion 12 to the floor of the vehicle body. This vehicle seat 10 is, for example, a driver's seat in a left-hand drive vehicle. If this vehicle seat 10 is, for example, a driver's seat in a right-hand drive vehicle, the configuration will be symmetrical to that of this embodiment.

[0024] The seat slide rail 20 has a lower rail 22 fixed to the floor of the vehicle body and an upper rail 24 supported so as to be slidable in the front-rear direction relative to the lower rail 22. The lower rail 22 and the upper rail 24 are formed in an elongated shape with the longitudinal direction being the front-rear direction. The seat slide rails 20 are respectively disposed below the left and right ends of the seat cushion 12.

[0025] A cushion frame 14 that forms the framework of the seat cushion 12 is connected to upper rails 24 of the left and right seat slide rails 20 via a well-known lifter mechanism (not shown). A resin finisher 16 that forms the left design surface of the seat cushion 12 is attached to the left end of the seat cushion 12. The lower end of a seat back 18 is connected to the rear end of the seat cushion 12 via a well-known reclining mechanism (not shown).

[0026] In the vehicle seat 10 configured as described above, an occupant is restrained by a three-point seat belt device 36. The seat belt device 36 is provided with a long, strip-shaped seat belt (webbing) 38. One longitudinal end (base end) of the seat belt 38 is fastened to a winding shaft of a retractor (not shown) provided, for example, at the lower end of a B-pillar of the vehicle. An intermediate longitudinal portion of the seat belt 38 is wound around a shoulder anchor (not shown) provided, for example, at the upper end of the B-pillar, and the other longitudinal end (tip end) of the seat belt 38 is fastened to a lap anchor 40, which is an anchor member for the seat belt.

[0027] The lap anchor 40 is engaged with the rear end of the upper rail 24 (hereinafter simply referred to as the "upper rail 24") provided on the left-side seat slide rail 20. A tongue plate (not shown) is slidably attached to the middle portion of the seat belt 38 between the shoulder anchor and the lap anchor 40. This tongue plate can be connected to, for example, a buckle (not shown) attached to the rear portion of the upper rail 24 provided on the right-side seat slide rail 20.

[0028] In the seat belt device 36 configured as described above, an occupant seated on the seat cushion 12 of the vehicle seat 10 connects the tongue plate to the buckle, thereby putting the occupant in a state of wearing the seat belt 38. In this state, the portion of the seat belt 38 from the shoulder anchor to the tongue plate serves as a shoulder belt that restrains the upper body of the occupant, and the portion of the seat belt 38 from the tongue plate to the lap anchor 40 serves as a lap belt that restrains the waist of the occupant.

[0029] Although the lap anchor 40 is considered a component of the vehicle seat 10 in this embodiment, it can also be regarded as a component of the seat belt device 36. The lap anchor 40 includes a locking plate 42 that is locked to the rear end of the upper rail 24, and a movable plate 48 that is rotatably connected to the locking plate 42 about a connecting shaft 46 that extends in the front-rear direction and to which the leading end of the seat belt 38 is locked. The locking plate 42 and the movable plate 48 are manufactured, for example, by press-forming a metal plate material.

[0030] 1 to 3, 5, and 6, the locking plate 42 is an elongated plate with its longitudinal direction extending in the front-to-rear direction and its thickness direction extending in the up-down direction. The locking plate 42 is overlaid on the upper surface of the rear riser 26 (see FIGS. 1 to 4) that is fixed to the upper surface of the rear portion of the upper rail 24. The rear riser 26 is manufactured by press-molding, for example, a metal plate, and has an elongated shape with its longitudinal direction extending in the front-to-rear direction. The rear riser 26 has a fixed portion 26A that is overlaid on the upper surface of the upper rail 24, and a vertical wall portion 26B that extends upward from the inner left-right end of the fixed portion 26A.

[0031] Circular bolt holes 27 are formed in the front end and the central portion in the front-rear direction of the fixed portion 26A, respectively, penetrating the fixed portion 26A in the up-down direction. A pair of front and rear bolts 30 are inserted into these bolt holes 27 and penetrate the upper wall portion 24A of the upper rail 24 from below. These bolts 30 are threadedly engaged with a pair of front and rear nuts 32 disposed on the upper surface of the fixed portion 26A, respectively. This fastens and fixes the fixed portion 26A to the upper surface of the upper rail 24. The vertical wall portion 26B has a generally triangular shape when viewed in the left-right direction. A circular link hole 28 is formed in the upper end of this vertical wall portion 26B and penetrates the vertical wall portion 26B in the left-right direction. One end of a link member (not shown), which is a component of the lifter mechanism described above, is rotatably connected to the vertical wall portion 26B using a shaft member (not shown) inserted into this link hole 28.

[0032] A circular through-hole 29 is formed in the rear end of the fixing portion 26A, penetrating the fixing portion 26A in the up-down direction. A rivet 34 fixed to the rear end of the upper rail 24 is inserted into this through-hole 29. The rivet 34 is arranged with its axis in the up-down direction and is inserted from above into a circular rivet hole 25 formed in the rear end of the upper wall portion 24A of the upper rail 24. A flange portion 34B is formed in the middle portion of the rivet 34 in the up-down direction, and this flange portion 34B contacts the edge of the rivet hole 25 from above. The lower end of the rivet 34 is crimped to the lower side of the upper wall portion 24A of the upper rail 24. This fixes the rivet 34 to the upper rail 24.

[0033] The head 34A of the rivet 34 is positioned above the fixed portion 26A of the rear riser 26. The locking plate 42 is locked to the upper rail 24 using this rivet 34. Specifically, the locking plate 42 is formed with an armhole 44 having a large diameter portion 44A and a small diameter portion 44B that is smaller in diameter than the large diameter portion 44A. The large diameter portion 44A is positioned forward of the small diameter portion 44B and is connected to the small diameter portion 44B. When the locking plate 42 is locked to the upper rail 24, the head 34A of the rivet 34 is inserted into the large diameter portion 44A, and the locking plate 42 is placed on top of the upper wall portion 24A of the upper rail 24. In this state, the locking plate 42 is slid forward relative to the upper rail 24, and the rivet 34 is inserted into the small diameter portion 44B. In this state, the head 34A of the rivet 34 is caught from above on the edge of the small diameter portion 44B, thereby preventing the locking plate 42 from falling off the upper rail 24.

[0034] A pair of front and rear support shafts 42A are formed on the outer left and right ends of the locking plate 42. The front and rear support shafts 42A are formed by bending a portion of the locking plate 42 into a cylindrical shape, and have a cylindrical shape with the front-to-rear direction as the axial direction. The front support shaft 42A is formed in the front part of the locking plate 42, and the rear support shaft 42A is formed in the rear part of the locking plate 42. These front and rear support shafts 42A correspond to the connecting shaft 46.

[0035] The connecting shaft 46 is cylindrical with its axial direction extending in the front-rear direction and constitutes a part of the lap anchor 40. The front portion of the connecting shaft 46 is press-fitted into the front support shaft portion 42A, and the rear portion of the connecting shaft 46 is press-fitted into the rear support shaft portion 42A. This fixes the connecting shaft 46 to the locking plate 42. A limiting portion 42B is formed at the outer end of the locking plate 42 in the left-right direction. This limiting portion 42B extends integrally from the center of the locking plate 42 in the front-rear direction outward in the left-right direction, and its tip side is bent upward. The connecting shaft 46 and limiting portion 42B correspond to the movable plate 48.

[0036] As shown in FIGS. 1 to 3 and 5, the movable plate 48 has a long plate shape. A pair of front and rear bearing portions 48A are formed at one longitudinal end (lower end) of the movable plate 48. The front and rear bearing portions 48A are formed by bending a portion of the movable plate 48 into a cylindrical shape, and have a cylindrical shape with the front-rear direction as the axial direction. A middle portion of the connecting shaft 46 in the front-rear direction is rotatably inserted into these bearing portions 48A. As a result, the movable plate 48 is connected to the locking plate 42 rotatably around the connecting shaft 46 (i.e., around an axis along the front-rear direction).

[0037] The rotation range of the movable plate 48 relative to the locking plate 42 is limited by a limiting portion 42B provided on the locking plate 42. Specifically, when the movable plate 48 rotates outward in the left-right direction relative to the locking plate 42, the limiting portion 42B of the locking plate 42 comes into contact with the movable plate 48, thereby restricting the rotation of the movable plate 48. In this restricted state, the movable plate 48 is in a position where it extends obliquely upward and outward in the left-right direction from the locking plate 42.

[0038] The movable plate 48 has a shape that is inclined forward as it approaches the other longitudinal end (upper end). A substantially rectangular belt locking hole 50 that penetrates the movable plate 48 in the plate thickness direction is formed on the other longitudinal end side of the movable plate 48. The tip of the seat belt 38 is inserted into this belt locking hole 50. The parts of the tip of the seat belt 38 before and after insertion into the belt locking hole 50 are overlapped and sewn together. In this way, the tip of the seat belt 38 is locked to the movable plate 48.

[0039] (Action and effect) Next, the operation and effects of this embodiment will be described.

[0040] In the vehicle seat 10 configured as described above, the lap anchor 40 includes a locking plate 42 and a movable plate 48. The locking plate 42 is locked to the upper rail 24 of the seat slide rail 20, and the tip of the seat belt 38 is locked to the movable plate 48. The movable plate 48 is connected to the locking plate 42 so as to be rotatable about an axis extending in the front-rear direction. This makes it possible to suppress variation in the position where the seat belt 38 is hooked around the occupant's waist in the front-rear direction of the seat, compared to a configuration in which the seat belt 38 rotates about an axis extending in the left-right direction of the seat, as with conventional anchor members.

[0041] The above effects will be further explained with reference to FIGS. 7 and 8. As shown in FIG. 7, in this embodiment, the movable plate 48 rotates left and right about the connecting shaft 46 extending in the front-rear direction relative to the locking plate 42 (see arrow R1 in FIG. 7). When an occupant wears the seat belt 38, tension acts on the seat belt 38 due to the winding force of the retractor. This causes the movable plate 48 to assume an upright position, and the seat belt 38 fits well around the occupant's waist. As a result, in the event of a vehicle collision, the occupant's waist can be quickly restrained by the seat belt 38. Moreover, with the configuration in which the movable plate 48 rotates left and right, variation in the front-rear position of the seat belt 38 (i.e., the lap belt) around the occupant's waist is unlikely to occur, thereby stabilizing the above-mentioned rapid restraint performance.

[0042] In contrast, in the comparative example shown in Fig. 8, the anchor member 100 to which the tip of the seat belt 38 is anchored is supported so as to be rotatable back and forth relative to the seat slide rail 20 (see arrow R2 in Fig. 8). In this comparative example, the seat belt 38 can be fitted tightly to the waist of the occupant by rotating the anchor member 100 back and forth, but the position of the seat belt 38 in the back and forth direction that wraps around the waist of the occupant is likely to vary. As a result, there is a risk of variation in the timing at which the waist of the occupant is restrained by the seat belt 38 in the event of a vehicle collision, but this variation can be suppressed in this embodiment.

[0043] Furthermore, in the above-described lap anchor 40, a limiting portion 42B provided on the locking plate 42 limits the range of rotation of the movable plate 48 relative to the locking plate 42. When the movable plate 48 abuts against this limiting portion 42B, the movable plate 48 extends obliquely outward and upward from the locking plate 42 in the left-right direction. This limiting portion 42B prevents the movable plate 48 from falling outward in the left-right direction. This improves the ease of installation of the cover 17 when a cover 17 that covers the lap anchor 40 is attached to the seat cushion 12, as shown in FIG. 9, for example. Furthermore, even in a configuration that does not include the above-described cover 17, the appearance of the vehicle seat 10 can be improved when the seat belt 38 is not fastened.

[0044] Furthermore, in the above-described lap anchor 40, the head 34A of the rivet 34 fixed to the rear end of the upper rail 24 of the seat slide rail 20 is inserted into the large diameter portion 44A of the potbelly hole 44 formed in the locking plate 42 and hooked onto the edge of the small diameter portion 44B of the potbelly hole 44. This allows the locking plate 42, i.e., the lap anchor 40, to be locked to the upper rail 24 without the use of tools.

[0045] Next, various modified examples of this embodiment will be described with reference to Figures 10 to 15. In a first modified example shown in Figure 10, the locking plate 42 does not have the limiting portion 42B, but instead has a leaf spring 52, which is a biasing member. This leaf spring 52 spans between the movable plate 48 and the locking plate 42, and biases the movable plate 48 in the upright direction relative to the locking plate 42.

[0046] 11, the locking plate 42 does not have the limiting portion 42B, but instead has a torsion coil spring 54, which is a biasing member. The torsion coil spring 54 is wound around the outer periphery of the connecting shaft 46, and both ends thereof are engaged with the locking plate 42 and the movable plate 48, biasing the movable plate 48 in the upright direction relative to the locking plate 42.

[0047] 12, a pair of front and rear limiting portions 42C are formed on the locking plate 42 on the left-right inner side relative to the movable plate 48. The front and rear limiting portions 42C are formed by cutting and raising a portion of the locking plate 42 upward, and limit the range of rotation of the movable plate 48 relative to the locking plate 42. When the movable plate 48 abuts against these limiting portions 42C, the movable plate 48 extends obliquely upward and outward in the left-right direction from the locking plate 42.

[0048] In the above-described first to third modified examples, the workability is improved, for example, when attaching the cover 17 to the seat cushion 12. In the above-described embodiment and the third modified example, the limiting portions 42B, 42C are provided on the locking plate 42, but the present invention is not limited to this, and the limiting portions may be provided on the movable plate.

[0049] In a fourth modified example shown in FIG. 13 , the locking plate 42 includes a locking portion 42D that is locked to the upper surface of the upper rail 24 by the rivet 34, an upward extending portion 42E that extends upward from the outer lateral end of the locking portion 42D and is bent inward in the lateral direction at a vertical intermediate portion, and a pair of front and rear support shafts 42F formed at the upper end of the upward extending portion 42E. The front and rear support shafts 42F are cylindrical with their axial direction extending in the longitudinal direction. The lower end of a movable plate 48 is rotatably connected to the locking plate 42 via a connecting shaft 46 press-fitted into the support shafts 42F. The connecting shaft 46 is positioned directly above the rivet 34. The bent portion at the vertical intermediate portion of the upward extending portion 42E and the bent portion between the locking portion 42D and the upward extending portion 42E are reinforced by ribs 42G and 42H, respectively.

[0050] In the fourth modified example, the load input to the locking plate 42 via the seat belt 38 and the movable plate 48 during a vehicle collision acts directly above the rivet 34, making it easier for the upper rail 24 to rise directly upward. As a result, this contributes to suppressing deformation of the upper rail 24 and the lower rail 22, for example.

[0051] 14, the locking plate 42 has a pair of left and right leaf springs 56 as restricting parts that restrict relative movement of the rivet 34 from the small diameter portion 44B side to the large diameter portion 44A side of the pothole 44. This prevents the locking plate 42 from accidentally coming off the rivet 34.

[0052] 15, the head 34A of the rivet 34 and the large diameter portion 44A of the keyhole hole 44 are formed in a keyhole shape when viewed from above. In this sixth modified example, when the locking plate 42 is attached to the upper rail 24, the head 34A of the rivet 34, which is formed in a keyhole shape, is inserted into the large diameter portion 44A, which is also formed in a keyhole shape. This prevents the locking plate 42 from being attached to the upper rail 24 incorrectly.

[0053] Although the present invention has been described above by showing embodiments and various modifications, the present invention can be implemented in various modifications without departing from the spirit of the present invention. Furthermore, it goes without saying that the scope of the present invention is not limited to the above-described embodiments and various modifications. [Explanation of symbols]
