[0003] [Patent Document 1] JP 2010-89738 A Summary of the Invention [Problem to be solved by the invention]

[0004] Since the above-mentioned lifter lever is made of sheet metal, there is a risk that the seat belt may be damaged by the edge of the lifter lever if the seat belt comes into contact with the lifter lever during a vehicle collision.

[0005] In consideration of the above, an object of the present invention is to provide a lifter lever that can prevent damage to a seat belt even when the seat belt is placed nearby, and a vehicle seat equipped with the lifter lever. [Means for solving the problem]

[0006] The lifter lever of the first embodiment comprises a sheet metal lever body whose rear end is connected to a lifter mechanism provided on the inside of an outer cover of a seat cushion of a vehicle seat, whose middle part in the fore-and-aft direction of the seat is inserted into an opening formed in the outer cover and whose front part of the seat is positioned outside the outer cover, a resin knob whose front part of the lever body fits inside, and a resin knob cap attached to the middle part of the lever body in the fore-and-aft direction of the seat and held to the lever body by the knob, and covering the part of the lever body between the outer cover and the knob.

[0007] In the first aspect of the lifter lever, the sheet metal lever body has an end portion on the rear side of the seat connected to a lifter mechanism provided inside an outer cover of a seat cushion of a vehicle seat. The lever body has an intermediate portion in the seat front-rear direction inserted into an opening formed in the outer cover, and a portion on the seat front side disposed outside the outer cover. The portion of the lever body on the seat front side is fitted inside a plastic knob. A plastic knob cap is attached to the intermediate portion of the lever body in the seat front-rear direction. The knob cap is held to the lever body by the knob and covers the portion of the lever body between the outer cover and the knob. This makes it possible to prevent contact between the sheet metal lever body and the seat belt even when the seat belt is disposed near the lifter lever, thereby preventing damage to the seat belt.

[0008] The lifter lever of the second aspect is the lifter lever of the first aspect, wherein the knob cap has a fitting portion that fits inside the knob.

[0009] In the lifter lever of the second aspect, the fitting portion of the knob cap fits into the inside of the knob together with the seat front portion of the lever body, which effectively prevents the knob cap from falling off the lever body.

[0010] The lifter lever of the third aspect is the first or second aspect, wherein the knob cap has a rear wall that contacts the lever body from the rear side of the seat and closes the insertion port of the lever body in the knob, an upper wall that extends from the rear wall toward the front side of the seat and contacts the lever body from above the seat, and a front wall that contacts the lever body from the side opposite the rear wall and the upper wall.

[0011] In the third embodiment of the lifter lever, the rear wall of the knob cap contacts the lever body from the rear side of the seat and closes the insertion port of the lever body in the knob. The top wall of the knob cap extends from the rear wall toward the front side of the seat and contacts the lever body from the upper side of the seat. The front wall of the knob cap contacts the lever body from the side opposite the rear wall and top wall. This makes it possible to suppress rattling of the knob cap relative to the lever body in the front-to-rear and up-down directions of the seat.

[0012] The lifter lever of the fourth aspect is the same as that of the second aspect, except that a rib protruding to one side in the seat width direction is formed on the inside of the knob, and the fitting portion of the knob cap is sandwiched between the rib and the lever body.

[0013] In the lifter lever of the fourth aspect, the fitting portion of the knob cap is sandwiched between the above-mentioned rib formed on the inside of the knob and the lever body, so that rattling of the knob cap relative to the lever body in the seat width direction can be suppressed.

[0014] A vehicle seat of a fifth aspect has a lifter mechanism provided inside an outer cover, an opening formed in the outer cover, a seat cushion on which an occupant sits, a seat back supporting the back of the occupant, and a lifter lever of any one of the first to fourth aspects, in which an end of the lever body on the rear side of the seat is connected to the lifter mechanism and a middle portion of the lever body in the seat fore-and-aft direction is inserted into the opening.

[0015] In the vehicle seat of the fifth aspect, the back of an occupant seated on the seat cushion is supported by the seat back. An end of the lever body on the rear side of the seat is connected to a lifter mechanism provided on the inside of an outer cover of the seat cushion. An intermediate portion of the lever body in the front-rear direction of the seat is inserted into an opening formed in the outer cover. This lever body is that of the lifter lever of any one of the first to fourth aspects, and therefore the above-mentioned effects can be obtained. Effect of the Invention

[0016] As described above, according to the present invention, even when the seat belt is disposed near the lifter lever, damage to the seat belt can be prevented. [Brief description of the drawings]

[0018] Hereinafter, a vehicle seat 10 according to one embodiment of the present invention will be described with reference to Figs. 1 to 19B. In each drawing, some reference symbols may be omitted in order to make the drawings easier to see. Arrows FR, OUT, IN, and UP shown as appropriate in each drawing indicate the front, widthwise outward, widthwise inward, and upward, respectively, of the vehicle seat 10. Hereinafter, when the front-rear, left-right, and up-down directions are simply used in the description, they will indicate the front-rear, left-right (widthwise), and up-down directions of the vehicle seat 10.

[0019] 1, a vehicle seat 10 according to this embodiment includes a seat cushion 12 on which an occupant sits, and a seat back 14 that supports the back of the occupant. The vehicle seat 10 is, for example, a driver's seat in a so-called left-hand drive vehicle, and is disposed on the left side of the front part of the vehicle interior.

[0020] An occupant is restrained in the vehicle seat 10 by a three-point seat belt device. A base end of a seat belt 16 (see FIG. 2; not shown in FIG. 1) provided in the seat belt device is engaged with a retractor provided, for example, near the lower end of a center pillar of the vehicle, and a tip end of the seat belt 16 is engaged with a floor part of the vehicle body on the left side (here, the outer side in the vehicle width direction) of the seat cushion 12. A tongue plate (not shown) provided in the middle part of the seat belt 16 is connected to a buckle 18 provided on the right side of the seat cushion 12, so that the occupant wears the seat belt 16.

[0021] A resin outer cover (side finisher) 20 is provided on the outer side of the seat cushion 12 in the seat width direction. A recess 22 recessed toward one side in the left-right direction (inner side in the seat width direction) is formed in the middle of the outer cover 20 in the front-rear direction. A lifter lever 30 is disposed in this recess 22. Although not shown, a reclining lever for operating the reclining mechanism of the vehicle seat 10 is provided behind the lifter lever 30.

[0022] 1 to 4, the lifter lever 30 is composed of a lever body 32, a knob 34, and a knob cap 46. The lever body 32 is manufactured by pressing a metal plate, and is an elongated plate with the longitudinal direction being the front-rear direction and the plate thickness direction being the left-right direction. The intermediate part of the lever body 32 in the front-rear direction is bent downward in a substantially trapezoidal shape, and the lever body 32 is substantially V-shaped in side view (see FIG. 13).

[0023] An intermediate portion of the lever body 32 in the front-rear direction is inserted into an opening 24 formed in a rear wall 22R of the recess 22. A rear side (a portion toward the rear of the seat) of the lever body 32 is disposed inside the outer cover 20. As shown in Fig. 2, a lifter mechanism 26 is disposed inside the outer cover 20, and a connecting portion 32A provided at the rear end portion of the lever body 32 is connected to the lifter mechanism 26 by means of bolt fastening or the like.

[0024] The lifter mechanism 26 is generally cylindrical with its axis in the left-right direction, and is disposed on one side in the left-right direction (inner side in the seat width direction) of the connecting portion 32A. The frame 13 of the seat cushion 12 is disposed on the other side in the left-right direction of the lifter mechanism 26, and the lifter mechanism 26 is fixed to the frame 13.

[0025] The lifter mechanism 26 constitutes the main body of a lifter device including a plurality of lifter links (not shown) that connect the frame 13 and a seat slide rail 28 attached to the floor of the vehicle body. In this lifter device, an output shaft (not shown) provided in the lifter mechanism 26 rotates when a lever body 32 of a lifter lever 30 is rotated in the vertical direction. A pinion fixed to the output shaft is engaged with a sector gear provided on one of the plurality of lifter links, and the plurality of lifter links rotate due to the rotation of the output shaft. This allows the seat cushion 12 to rise and fall.

[0026] The front side of the lever body 32 (the portion on the seat front side) is disposed in the recess 22 of the outer cover 20, and is disposed outside the outer cover 20. The front side of the lever body 32 fits inside the knob 34. The knob 34 is manufactured, for example, by injection molding of resin, and is substantially box-shaped with the longitudinal direction being the front-rear direction, as shown in Figures 5 and 6. The vertical dimension of the knob 34 is set to be larger than the horizontal dimension, and the vertical dimension decreases toward the front.

[0027] An insertion port 36 for the lever body 32 is formed at the rear end of the knob 34. The front side of the lever body 32 is inserted into the inside of the knob 34 through this insertion port 36. As shown in Fig. 5, recesses 38, 40 are formed on the top surface and one of the surfaces in the left-right direction (the surface on the outer side in the seat width direction) of the knob 34 so that an occupant seated in the vehicle seat 10 can place his / her fingers on the knob 34 when operating the lifter lever 30.

[0028] As shown in Fig. 6, an elastically deformable locking claw 42 is provided on the front side of the knob 34. This locking claw 42 is formed on the inner wall 34A of the knob 34 on the inner side in the seat width direction. A locking hole (not shown) into which the locking claw 42 fits is formed on the front side of the lever body 32 that is inserted into the inside of the knob 34. This fitting causes the knob 34 to be locked to the lever body 32. In addition, two upper and lower abutment ribs 44 extending in the front-rear direction are formed on the inside of the knob 34 near the insertion port 36. The upper and lower abutment ribs 44 protrude inward in the seat width direction from the outer wall 34B of the knob 34 on the outer side in the seat width direction.

[0029] 2 to 4, a knob cap 46 is attached to the front-rear intermediate portion of the lever body 32. As shown in Figures 7 and 8, the knob cap 46 is manufactured by, for example, injection molding of resin, and integrally includes a rear wall 46A, a side wall 46B, an upper wall 46C, a front wall 46D, an upper covering wall 46E, and a side covering wall 46F.

[0030] The rear wall 46A has a plate shape with a vertical direction as its longitudinal direction and a plate thickness direction approximately in the front-rear direction, and is slightly inclined forward with respect to the vertical direction. The lower part of the rear wall 46A has a cutout at the inner side in the seat width direction, and the dimension in the left-right direction is smaller than that of the upper part of the rear wall 46A. The side wall 46B extends forward from the outer part in the seat width direction on the front surface of the rear wall 46A, has a plate thickness direction in the left-right direction, and is pentagonal in the left-right direction. A plurality of holes 48 for removing weight are formed in the side wall 46B. The upper side of the front edge part of the side wall 46B is inclined upward toward the rear side, and the lower side of the front edge part of the side wall 46B is inclined downward toward the rear side.

[0031] The upper wall 46C extends from the upper edge of the side wall 46B toward the inside in the seat width direction and has a plate shape with the plate thickness direction being approximately in the up-down direction. The front wall 46D extends from the lower side of the front edge of the side wall 46B toward the inside in the seat width direction. The front wall 46D is divided into a front wall main body 46D1 and a clearance-reducing flange 46D2 arranged diagonally rearward and downward from the front wall main body 46D1. A slit 50 is formed between the front wall main body 46D1 and the clearance-reducing flange 46D2. As shown in FIG. 12, two upper and lower bead portions 52 extending in the seat width direction are formed on the rear surface of the clearance-reducing flange 46D2.

[0032] The upper covering wall 46E extends rearward from the vertical center of the rear wall 46A and is a plate-like member with the vertical direction being the plate thickness direction. The side covering wall 46F extends rearward from the seat width direction inner edge of the lower part of the rear wall 46A. The upper edge of the side covering wall 46F is connected to the seat width direction outer edge of the upper covering wall 46E. The side covering wall 46F extends rearward further than the upper covering wall 46E. The lower edge of the side covering wall 46F is formed with a bent portion 54 that is bent inward in the seat width direction.

[0033] 9 to 11, the front-to-rear intermediate portion of the lever body 32 to which the knob cap 46 is attached has a horizontal portion 32B extending in the front-to-rear direction and an inclined portion 32C extending obliquely forward and upward from the front end of the horizontal portion 32B. The rear edge portion of the inclined portion 32C is inclined so as to approach the front side as it approaches the upper side, and the inclination is gentler at the upper side than at the lower side.

[0034] The rear wall 46A of the knob cap 46 contacts the lower side of the rear edge of the inclined portion 32C from the rear side, and the upper wall 46C of the knob cap 46 contacts the upper side of the rear edge of the inclined portion 32C from the rear side and above. The front wall main body 46D1 of the front wall 46D of the knob cap 46 closely faces the front edge of the inclined portion 32C from the front side and below. A claw portion 56 protruding toward the rear side and upward side is formed on the edge portion on the inner side in the seat width direction on the rear surface of the front wall main body 46D1. The claw portion 56 hooks onto the front edge of the inclined portion 32C from the inner side in the seat width direction, so that the knob cap 46 is engaged with the lever main body 32.

[0035] The two bead portions 52 formed on the clearance-reducing flange 46D2 of the front wall 46D contact the front edge of the inclined portion 32C from the front side and the lower side (i.e., the side opposite the rear wall 46A and the upper wall 46C from the inclined portion 32C). The clearance-reducing flange 46D2 is configured to bend, thereby absorbing dimensional errors of the knob cap 46 and the lever body 32, and ensuring contact between the rear wall 46A, the upper wall 46C, and the clearance-reducing flange 46D2 and the lever body 32. As a result, the knob cap 46 is configured to be prevented from rattling in the front-rear and up-down directions relative to the lever body 32.

[0036] The upper covering wall 46E faces the upper edge of the horizontal portion 32B of the lever body 32 from above in contact with or in close proximity thereto, and the side covering wall 46F faces the horizontal portion 32B from the outer side in the seat width direction in contact with or in close proximity thereto. A bent portion 54 formed on the lower edge of the side covering wall 46F faces the lower edge of the horizontal portion 32B from below in contact with or in close proximity thereto.

[0037] The front side of the lever body 32 to which the knob cap 46 is attached as described above is fitted inside the knob 34 as shown in Fig. 13. At this time, the knob 34 is brought straight toward the lever body 32 in the front-to-rear direction as shown by the arrow S in Fig. 13, and the front side of the lever body 32 is inserted inside the knob 34. Then, the locking claw 42 of the knob 34 fits into the locking hole of the lever body 32, so that the knob 34 is locked to the lever body 32.

[0038] The rear wall 46A, side wall 46B, top wall 46C and front wall 46D of the knob cap 46 form a fitting portion 47 that fits inside the knob 34. This fitting allows the knob cap 46 to be held on the lever body 32 by the knob 34, preventing the knob cap 46 from falling off from the lever body 32. In this fitted state, as shown in Figures 3 and 4, the rear wall 46A of the knob cap 46 blocks the insertion port 36 of the knob 34. Also, as shown in Figure 14, the side wall 46B that fits inside the knob 34 (i.e., the fitting portion 47) is configured to be sandwiched between the upper and lower ribs 44 formed on the outer wall 34B of the knob 34 and the lever body 32.

[0039] The upper covering wall 46E and the side covering wall 46F of the knob cap 46 are arranged between the opening 24 formed in the rear wall 22R of the recess 22 of the outer cover 20 and the knob 34, and the exposed portion of the lever body 32 between the outer cover 20 and the knob 34 is configured to be covered from the upper side and the outside in the seat width direction by the upper covering wall 46E and the side covering wall 46F.

[0040] Next, the operation and effects of this embodiment will be described. In the vehicle seat 10 configured as described above, the back of an occupant seated on the seat cushion 12 is supported by the seat back 14. A rear end of a lever body 32 of a lifter lever 30 is connected to a lifter mechanism 26 provided inside an outer cover 20 of the seat cushion 12. The lever body 32 has a front-rear middle portion inserted into an opening 24 formed in the outer cover 20, and a front side is disposed outside the outer cover 20. The front side of the lever body 32 is fitted inside a plastic knob 34. A plastic knob cap 46 is attached to the front-rear middle portion of the lever body 32.

[0041] The knob cap 46 is held to the lever body 32 by the knob 34, and covers the portion of the lever body 32 between the rear wall 22R of the outer cover 20 and the knob 34. This makes it possible to prevent contact between the sheet metal lever body 32 and the seat belt 16 even if the seat belt 16 arranged near the lifter lever 30 gets into the gap between the rear wall 22R of the outer cover 20 and the knob 34 during a vehicle collision and interferes with the lifter lever 30 (see FIG. 15). As a result, it becomes possible to prevent damage to the seat belt 16.

[0042] The above-mentioned effects will be further explained using a comparative example shown in Fig. 16A to Fig. 19B. As shown in Fig. 16A and Fig. 16B, in this comparative example, the lifter lever 30' does not have a knob cap 46, but the other configurations are the same as those of this embodiment. As shown in Fig. 17A and Fig. 17B, in the event of a vehicle collision, the tip side of the seat belt 16 (hereinafter simply referred to as "seat belt 16") is pulled forward and inward in the seat width direction by the load from the occupant (see arrows F and C), so that the outer cover 20 is crushed inward in the seat width direction, and the seat belt 16 comes into contact with the rear end surface of the knob 34.

[0043] When the seat belt 16 is further pulled forward and inward in the seat width direction in this state, the seat belt 16 enters (bites into) the gap between the rear wall 22R of the outer cover 20 and the knob 34, as shown in Fig. 18. When the tip of the seat belt 16 is further pulled forward and inward in the seat width direction in this state, the seat belt 16 interferes with the sheet metal lever main body 32, as shown in Fig. 19A and Fig. 19B. As a result, the seat belt 16 may be damaged, such as unraveled, but this can be avoided in this embodiment.

[0044] Moreover, in this embodiment, the behavior of the seat belt 16 when the seat belt 16 interferes with the knob cap 46 can be controlled by adjusting the R shape and surface roughness of the rear wall 46A, the upper covering wall 46E, and the side covering wall 46F of the knob cap 46. Also, since the knob cap 46 is a separate part from the knob 34, it is easier to attach the knob cap 46 to the lever body 32 compared to when the knob cap 46 and the knob 34 are integrated. In other words, when the knob cap 46 and the knob 34 are integrated, it is necessary to take measures such as twisting the knob 34 when inserting the front side of the lever body 32 into the inside of the knob 34, which makes the installation work complicated. However, in this embodiment, the front side of the lever body 32 to which the knob cap 46 is attached can be inserted straight into the inside of the knob 34, making the installation work easy.

[0045] In this embodiment, the fitting portion 47 of the knob cap 46 fits into the inside of the knob 34 together with the front side of the lever body 32. This makes it possible to effectively prevent the knob cap 46 from falling off from the lever body 32.

[0046] In this embodiment, the rear wall 46A of the knob cap 46 contacts the lever body 32 from the rear side and closes the insertion port 36 of the knob 34. The top wall 46C of the knob cap 46 extends forward from the rear wall 46A and contacts the lever body 32 from above. The front wall 46D of the knob cap 46 contacts the lever body 32 from the side opposite the rear wall 46A and top wall 46C. This makes it possible to suppress rattling of the knob cap 46 relative to the lever body 32 in the front-to-rear and up-down directions.

[0047] In this embodiment, upper and lower ribs 44 that protrude inward in the seat width direction are formed on the inside of the knob 34 near the insertion port 36, and a fitting portion 47 of the knob cap 46 is sandwiched between these ribs 44 and the lever body 32. This makes it possible to suppress rattling of the knob cap 46 relative to the lever body 32 in the seat width direction.

[0048] Although the present invention has been described above by way of the embodiment, the present invention can be modified and embodied without departing from the spirit and scope of the present invention. Furthermore, the scope of the present invention is not limited to the above embodiment. [Explanation of symbols]
