[0003] [Patent Document 1] Japanese Utility Model Application Publication No. 6-44629 Summary of the Invention [Problem to be solved by the invention]

[0004] In the above-mentioned prior art, a pair of handles on a plastic bag can be hooked onto the left and right hanging arms rotated to the use position, thereby holding the plastic bag in an open state. Furthermore, if the plastic bag contains, for example, a take-out drink or lunch box, the drink or lunch box can be kept horizontal. Furthermore, the left and right hanging arms can be stowed away when not in use, so they do not get in the way of passengers. However, there is room for improvement in terms of simplifying the structure.

[0005] An object of the present invention is to provide a rotary hook that can suitably hang a plastic shopping bag and has a simplified structure, and a vehicle seat equipped with the rotary hook. [Means for solving the problem]

[0006] The first embodiment of the swivel hook comprises a support shaft portion provided on the back of the seat back of a vehicle seat, and a hook portion whose shaft portion at one longitudinal end is rotatably supported on the support shaft portion, bends at a bending portion provided in the middle of the longitudinal direction, and is rotatable between a use position in which the bag hook portion at the other longitudinal end extends along the horizontal direction of the vehicle and a storage position in which the bag hook portion is stored along the back of the seat back.

[0007] According to the first aspect of the rotatable hook, a support shaft is provided on the back of the seat back of a vehicle seat. A shaft portion at one longitudinal end of the hook portion is rotatably supported on the support shaft. The hook portion is bent at a bent portion provided in the middle of the longitudinal direction. This hook portion is rotatable between a use position in which the bag hook portion at the other longitudinal end extends along the horizontal direction of the vehicle, and a storage position in which the bag hook portion is stored along the back of the seat back.

[0008] With this rotating hook, for example, if the bag hooking portion of the hook is made longer, the pair of handles of the plastic bag can be hooked apart from each other on the bag hooking portion of the hook portion rotated to the use position, allowing the plastic bag to be hung conveniently. Furthermore, because the hook portion with a bent portion is configured to rotate relative to the support shaft, it is possible to hold the hook portion in the use position by, for example, the weight of the contents inside the plastic bag hooked on the bag hooking portion. As a result, a locking member or the like for locking the hook portion in the use position is not required, simplifying the structure.

[0009] The second aspect of the rotating hook is the same as the first aspect, except that when the hook portion is in the use position, multiple protrusions that convex toward the upper side of the vehicle are spaced apart in the longitudinal direction of the bag hooking portion.

[0010] According to the second aspect of the rotating hook, the bag hooking portion of the hook portion is provided with multiple protrusions as described above, thereby preventing or suppressing the handle of a plastic bag hooked on the bag hooking portion from shifting longitudinally relative to the bag hooking portion.

[0011] The third aspect of the rotating hook is the first or second aspect, wherein the shaft portion has a convex portion that protrudes radially from the shaft portion, and the support shaft portion has a first abutment portion against which the convex portion abuts when the hook portion is positioned in the use position, and a second abutment portion against which the convex portion abuts when the hook portion is positioned in the storage position.

[0012] According to the third aspect of the swivel hook, when the hook is in the use position, the convex portion formed on the shaft of the hook abuts against the first abutment portion of the support shaft, and when the hook is in the storage position, the convex portion abuts against the second abutment portion of the support shaft, thereby making it possible to limit the rotation of the hook with a simple configuration.

[0013] A fourth aspect of the rotating hook is a rotating hook as described in claim 3, wherein in the third aspect, the support shaft portion has a first sliding contact portion that slides against the convex portion when the hook portion rotates near the use position, and a second sliding contact portion that slides against the convex portion when the hook portion rotates near the storage position.

[0014] According to the fourth aspect of the swivel hook, when the hook portion rotates near the use position, the convex portion of the hook portion slides against the first sliding contact portion of the support shaft portion, and when the hook portion rotates near the storage position, the convex portion of the hook portion slides against the second sliding contact portion of the support shaft portion. In this way, sliding resistance is generated when the convex portion slides against the first sliding contact portion and the second sliding contact portion, making it possible to prevent inadvertent rotation of the hook portion from the use position and the storage position with a simple configuration.

[0015] The fifth aspect of the rotating hook is the first or second aspect, wherein the shaft portion has a convex portion that protrudes radially from the shaft portion, and the support shaft portion has a first fitting portion into which the convex portion fits when the hook portion is in the use position, and a second fitting portion into which the convex portion fits when the hook portion is in the storage position, and each of the fittings is released by displacing the shaft portion axially relative to the support shaft portion.

[0016] According to the fifth aspect of the rotatable hook, when the hook portion is in the use position, a convex portion formed on the shank of the hook portion fits into the first fitting portion of the support shaft portion, and when the hook portion is in the storage position, the convex portion fits into the second fitting portion of the support shaft portion. This makes it possible to restrict rotation of the hook portion with a simple configuration. Furthermore, since the above-mentioned fittings are released by axially displacing the shank of the hook portion relative to the support shaft portion, the operation for rotating the hook portion is easy.

[0017] The sixth aspect of the rotating hook is any one of the first to fifth aspects, in which a groove is formed in the seat back to accommodate the bag hooking portion of the hook portion when it is positioned in the storage position.

[0018] In the rotating hook of the sixth aspect, when the hook portion is rotated to the storage position, the bag hook portion of the hook portion is accommodated in a groove formed in the seat back, which prevents the bag hook portion from getting caught on an occupant when, for example, the occupant gets in or out of the vehicle.

[0019] A vehicle seat of the seventh aspect includes a seat cushion on which an occupant sits, a seat back that supports the back of the occupant, and one or more rotating hooks of any one of the first to sixth aspects provided on the back of the seat back.

[0020] In the vehicle seat of the seventh aspect, the back of an occupant seated on a seat cushion is supported by a seat back. One or more rotary hooks are provided on the back of the seat back. The rotary hook is one of the first to sixth aspects, and therefore the above-mentioned effects can be obtained. [Effects of the Invention]

[0021] As described above, the rotary hook and vehicle seat according to the present invention can suitably hang shopping bags and can simplify the structure. [Brief explanation of the drawings]

[0023] First Embodiment A vehicle seat 10 according to a first embodiment of the present invention will be described below with reference to Figures 1 to 7. Note that in each figure, some reference numerals may be omitted to make the drawings easier to understand. Arrows FR, RH, and UP, which are appropriately shown in each figure, respectively indicate the front, 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.

[0024] 1, a vehicle seat 10 according to this embodiment includes a seat cushion 12 on which an occupant sits, a seat back 14 that supports the occupant's back, and a headrest 16 that supports the occupant's head. The vehicle seat 10 is, for example, a front seat of a vehicle.

[0025] As shown in Fig. 2, the seat back 14 includes a back frame 18 as a framework member, a back pad (not shown) as a cushion body that covers the back frame 18, and a trim cover 20 as a cover that covers the back pad. The back frame 18 is formed into a generally frame-like shape by joining together a plurality of press-molded metal plates. The back pad is formed from a foam such as urethane foam. The trim cover 20 is formed into a bag-like shape by sewing together a plurality of cover pieces made of, for example, cloth, leather, synthetic leather, or the like.

[0026] As shown in Figure 2, an upper panel 22 extending in the left-right direction is provided on the top of the back frame 18. This upper panel 22 is made of, for example, a press-formed metal plate and is disposed on the back of the seat back 14. The upper panel 22 has a rearward-inclined wall portion 22A that slopes upward as it extends rearward, and a forward-inclined wall portion 22B that extends forward and upward from the upper end of the rearward-inclined wall portion 22A. A support shaft 32 that forms part of the rotatable hook 30 is provided in the center of the rearward-inclined wall portion 22A in the left-right direction.

[0027] 2, swivel hook 30 is a hook for hanging a carrier bag such as a shopping bag 24 having a pair of handles (grip) 24A, 24B, and is composed of a support shaft 32 and a hook body 52. ​​Support shaft 32 is composed of a bearing 34 provided in the center of upper panel 22 in the left-right direction, and a rotation limiting part 38 fixed to upper panel 22.

[0028] 3 to 7, the bearing portion 34 is formed by a part of the rearwardly inclined wall portion 22A of the upper panel 22. A circular bearing hole 36 is formed in the bearing portion 34 and passes through the bearing portion 34. Note that the bearing portion 34 may be manufactured separately from the upper panel 22 and fixed to the upper panel 22.

[0029] The rotation limiting portion 38 is made of, for example, a press-formed metal plate and has a generally U-shaped cross section. The rotation limiting portion 38 is made up of a rear wall portion 38A that faces the bearing portion 34 (i.e., the rearwardly inclined wall portion 22A) from the rearward and downward sides and is spaced apart from the bearing portion 34, and left and right side wall portions 38B that extend from the left and right ends of the rear wall portion 38A toward the upper panel 22. A generally circular through-hole 40 is formed in the rear wall portion 38A. The left and right side wall portions 38B are fixed to the rearwardly inclined wall portion 22A by means of welding or the like.

[0030] 1 to 7, the hook portion 50 is made up of a hook main body 52 and a resin portion 58. The hook main body 52 is made up of, for example, a bent metal round bar material. The resin portion 58 is made up of, for example, a resin molded integrally with the hook main body 52.

[0031] One longitudinal end of the hook body 52 is a cylindrical shaft portion 52A. This shaft portion 52A is inserted into the bearing hole 36 of the bearing portion 34 and is rotatably supported by the bearing portion 34. As shown in Fig. 4, the shaft portion 52A has a flange-shaped retaining portion 52A1, which restricts axial displacement of the shaft portion 52A relative to the bearing portion 34.

[0032] The shank 52A of the hook main body 52 is inserted into a through-hole 40 formed in the rear wall 38A of the rotation limiting portion 38. The shank 52A is formed with a protrusion 54 that protrudes radially from the shank 52A. The protrusion 54 is disposed within the through-hole 40. As shown in FIG. 5 , the through-hole 40 has a large-diameter portion 40A in approximately its upper half and a small-diameter portion 40B in approximately its lower half, which is smaller in diameter than the large-diameter portion 40A. Stepped first and second abutment portions 42 and 44 are provided between the large-diameter portion 40A and the small-diameter portion 40B. The first abutment portion 42 is disposed on the left side of the shank 52A, and the second abutment portion 44 is disposed on the right side of the shank 52A.

[0033] Furthermore, in the large diameter portion 40A of the through hole 40, a first sliding contact portion 46 that protrudes radially inward of the large diameter portion 40A is provided near the first abutment portion 42, and a second sliding contact portion 48 that protrudes inward of the large diameter portion 40A is provided near the second abutment portion 44. The large diameter portion 40A is reduced in diameter at the locations where the first abutment portion 42 and the second abutment portion 44 are provided.

[0034] The hook body 52 has a longitudinal intermediate portion that penetrates the trim cover 20. A bent portion 52B is provided in the longitudinal intermediate portion of the hook body 52, and the hook body 52 is bent at this bent portion 52B. The other longitudinal end of the hook body 52 is embedded in a resin portion 58. The other longitudinal end of the hook body 52 and the resin portion 58 form a bag hooking portion 56. The resin portion 58 has a generally square bar-like outer shape that is longitudinal in the longitudinal direction of the hook body 52. ​​The resin portion 58 has a plurality of (here, four) protrusions 58A that protrude radially outward from the resin portion 58 and are spaced apart from one another in the longitudinal direction of the resin portion 58. These protrusions 58A are provided so as to protrude upward when the hook portion 50 is in a use position described below.

[0035] The hook portion 50 rotates around the axis of the shaft portion 52A relative to the support shaft portion 32, thereby rotating between a use position shown by a solid line in Fig. 2 and a storage position shown by a two-dot chain line in Fig. 2. In the use position, the bag hook portion 56 of the hook portion 50 extends in the horizontal direction of the vehicle (here, the front-to-rear direction). In the storage position, the bag hook portion 56 of the hook portion 50 is stored along the back surface of the seat back 14.

[0036] As shown in Fig. 6, when the hook portion 50 is in the use position, the protrusion 54 provided on the shaft portion 52A of the hook main body 52 abuts against the first abutment portion 42 of the support shaft portion 32. In this state, the bag hooking portion 56 extends in the front-to-rear direction on the rear side of the support shaft portion 32. As shown in Fig. 7, when the hook portion 50 is in the storage position, the protrusion 54 of the hook portion 50 abuts against the second abutment portion 44 of the support shaft portion 32. In this state, the bag hooking portion 56 extends below the support shaft portion 32 in a direction substantially vertical to the vehicle (i.e., substantially up-and-down).

[0037] The range of rotation of the hook portion 50 relative to the support shaft portion 32 is limited between the first abutment portion 42 and the second abutment portion 44. When the hook portion 50 rotates near the use position, the convex portion 54 of the hook portion 50 comes into sliding contact with the first sliding contact portion 46 of the support shaft portion 32, and when the hook portion 50 rotates near the storage position, the convex portion 54 of the hook portion 50 comes into sliding contact with the second sliding contact portion 48.

[0038] 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 single rotatable hook 30 is provided on the back of the seat back 14. In this rotatable hook 30, a support shaft 32 is provided on the back of the seat back 14, and a shaft 52A at one longitudinal end of a hook portion 50 is rotatably supported on the support shaft 32. The hook portion 50 is bent at a bent portion 52B provided in the longitudinal middle portion of the hook body 52. ​​The hook portion 50 is rotatable between a use position in which a bag hooking portion 56 at the other longitudinal end extends along the front-to-rear direction, and a storage position in which the bag hooking portion 56 is stored along the back surface of the seat back 14.

[0039] In this swivel hook 30, the bag hooking portion 56 of the hook portion 50 is formed long, so that, as shown in Fig. 2, the pair of handles 24A, 24B of a plastic bag 24 can be hooked apart from each other on the bag hooking portion 56 of the hook portion 50 rotated to the use position, allowing the plastic bag 24 to be hung in a suitable manner. In other words, for example, if the plastic bag 24 contains a take-out drink or lunch box, the drink or lunch box can be kept horizontal, preventing the drink from leaking or the lunch box from becoming unevenly distributed. Moreover, when the swivel hook 30 is not needed, the hook portion 50 can be stored in the storage position, so the swivel hook 30 does not get in the way of passengers.

[0040] Furthermore, in this rotating hook 30, the hook portion 50 having the bent portion 52B is configured to rotate relative to the support shaft 32, so that the hook portion 50 can be held in the use position by, for example, the weight of the contents inside the plastic bag 24 hung on the bag hook portion 56. As a result, a locking member or the like for locking the hook portion 50 in the use position is not required, thereby simplifying the structure.

[0041] Furthermore, in this rotating hook 30, bag hooking portion 56 of hook portion 50 is provided with a plurality of protrusions 58A that protrude upward when hook portion 50 is in the use position and are spaced apart in the longitudinal direction of bag hooking portion 56. This prevents or inhibits handles 24A, 24B of plastic bag 24 hooked on bag hooking portion 56 from shifting in position in the longitudinal direction relative to bag hooking portion 56.

[0042] Furthermore, with this rotating hook 30, when the hook portion 50 is in the use position, the convex portion 54 formed on the shaft portion 52A of the hook portion 50 abuts against the first abutment portion 42 of the support shaft portion 32, and when the hook portion 50 is in the storage position, the convex portion 54 abuts against the second abutment portion 44 of the support shaft portion 32. This makes it possible to limit the rotation of the hook portion 50 with a simple configuration.

[0043] Furthermore, with this rotating hook 30, when the hook portion 50 rotates near the use position, the convex portion 54 of the hook portion 50 slides against the first sliding contact portion 46 of the support shaft portion 32, and when the hook portion 50 rotates near the storage position, the convex portion 54 of the hook portion 50 slides against the second sliding contact portion 48 of the support shaft portion 32. In this way, sliding resistance is generated when the convex portion 54 slides against the first sliding contact portion 46 and the second sliding contact portion 48, so that it is possible to prevent inadvertent rotation of the hook portion 50 from the use position and the storage position with a simple configuration.

[0044] In the first embodiment, the hook portion 50 has the resin portion 58, but the present invention is not limited to this. The hook portion 50 may have no resin portion 58, i.e., the bag hooking portion 56 may be formed only by the other longitudinal end of the hook body 52. ​​In this case, for example, by bending the other longitudinal end of the hook body 52 into a wave shape, it is possible to prevent or suppress misalignment of the handles 24A, 24B with respect to the other longitudinal end of the hook body 52 (i.e., the bag hooking portion 56).

[0045] Next, another embodiment of the present invention will be described. Note that the same reference numerals as in the first embodiment are used for the configurations and operations that are basically the same as those in the first embodiment, and the description thereof will be omitted.

[0046] <Second embodiment> As shown in Fig. 8, in a vehicle seat 60 according to the second embodiment of the present invention, two rotatable hooks 30L, 30R are provided on the rear portion of the seat back 14. The left and right rotatable hooks 30L, 30R are arranged spaced apart in the left-right direction and are configured symmetrically. As in the first embodiment, the left and right rotatable hooks 30L, 30R are attached to the upper panel 22 of the back frame 18 (see Fig. 9). This upper panel 22 is arranged with the thickness direction of the main part oriented approximately in the front-rear direction.

[0047] 9 to 12, the left-side swivel hook 30L, like the swivel hook 30L according to the first embodiment, is composed of a spindle 32 and a hook 50. In this swivel hook 30L, the hook 50 is rotatable about the spindle 32 between a use position in which the bag hooking portion 56 extends in the horizontal direction of the vehicle (here, the left-right direction) and a storage position in which it is stored along the back of the seat back 14.

[0048] 10 and 11, when the hook portion 50 of the left rotatable hook 30L is in the use position, the convex portion 54 provided on the shaft portion 52A of the hook body 52 abuts against the first abutment portion 42 of the support shaft portion 32. In this state, the bag hooking portion 56 extends in the left-right direction on the right side of the support shaft portion 32. As shown in FIG. 12, when the hook portion 50 is in the storage position, the convex portion 54 of the hook portion 50 abuts against the second abutment portion 44 of the support shaft portion 32. In this state, the bag hooking portion 56 extends in the substantially vertical direction of the vehicle (i.e., substantially up-down direction) on the lower side of the support shaft portion 32. Although not shown in the drawings, the right rotatable hook 30R has a similar configuration to the left rotatable hook 30L, except that it is configured symmetrically.

[0049] Other than the above, this embodiment is similar in configuration to the first embodiment. In this embodiment, as shown in Fig. 8, when the hook portions 50 of the left and right rotatable hooks 30L, 30R are rotated to the use position, the handles 24A, 24B of the plastic bag 24 can be hooked onto the hook portions 50, so that the plastic bag 24 can be hung appropriately with a simple configuration. Moreover, when the rotatable hooks 30L, 30R are not needed, the hook portions 50 can be stored in the storage position, so that the rotatable hooks 30 do not get in the way of the passengers.

[0050] <Third embodiment> 13 and 14, in a vehicle seat 70 according to the third embodiment of the present invention, similar to the vehicle seat 10 according to the first embodiment, one rotary hook 30 is provided on the rear of the seat back 14. A groove 72 is formed on the rear surface of the seat back 14 to accommodate the bag hook portion 56 of the hook portion 50 when it is in the storage position. This groove 72 extends in the height direction of the seat back 14.

[0051] In the vehicle seat 70, the rear wall 38A of the rotation limiting portion 38 of the support shaft 32 is provided with a first fitting portion 74 (see FIGS. 16, 18, and 20) into which the protrusion 54 of the shaft 52A fits when the hook 50 is in the use position (see FIG. 19), and a second fitting portion 76 (see FIGS. 16, 18, and 20) into which the protrusion 54 of the shaft 52A fits when the hook 50 is in the storage position (see FIG. 15). The first fitting portion 74 and the second fitting portion 76 are notches formed in the edge of the through-hole 40.

[0052] The shaft 52A of the hook 50 is axially displaceable within a predetermined range relative to the support shaft 32, and is biased toward the upper panel 22 (diagonally upward toward the front) by a biasing member (not shown). When the hook 50 is in the use position, the convex portion 54 fits into the first fitting portion 74, thereby restricting rotation of the hook 50 relative to the support shaft 32. When the hook 50 is in the storage position, the convex portion 54 fits into the second fitting portion 76, thereby restricting rotation of the hook 50 relative to the support shaft 32.

[0053] When the occupant rotates the hook portion 50 from the storage position to the use position, the hook portion 50 is pulled diagonally downward and rearward (see arrow P1 in FIGS. 15 and 16 ), causing the protrusion 54 of the shaft 52A to come out of the first fitting portion 74, disengaging the protrusion 54 from the first fitting portion 74, and thus releasing the restriction on rotation.

[0054] When the hook portion 50 is rotated between the storage position and the use position (see arrow T in Figures 17 and 18), the protrusion 54 is disposed between the first fitting portion 74 and the second fitting portion 76, as shown in Figure 18. In this state, rotation of the hook portion 50 relative to the support shaft portion 32 is permitted.

[0055] When the hook portion 50 reaches the storage position, the protrusion 54 of the shaft portion 52A faces the second fitting portion 76, and the biasing force of the biasing member causes the protrusion 54 to fit into the second fitting portion 76 (see arrow P2 in FIGS. 19 and 20). This again restricts the rotation of the hook portion 50 relative to the support shaft portion 32.

[0056] In this embodiment, the configuration is the same as in the first embodiment except for the above. In this embodiment, too, a plastic bag 24 can be hung conveniently from hook portion 50 in the use position, and the structure can be simplified. Furthermore, in this embodiment, when hook portion 50 is in the use position, convex portion 54 of shaft portion 52A fits into first fitting portion 74 of support shaft portion 32, and when hook portion 50 is in the storage position, convex portion 54 of shaft portion 52A fits into second fitting portion 76 of support shaft portion 32. This makes it possible to restrict rotation of hook portion 50 with a simple configuration.

[0057] Moreover, the above-mentioned engagements are released by displacing the shaft 52A of the hook 50 in the axial direction relative to the support shaft 32, facilitating the operation of rotating the hook 50. Furthermore, when the hook 50 is rotated to the storage position, the bag hook 56 of the hook 50 is accommodated in a groove 72 formed in the rear surface of the seat back 14. This prevents the bag hook 56 from getting caught on an occupant, for example, when the occupant gets in or out of the vehicle.
