Summary of the Invention

Problems to be Solved by the Invention

[0004] By the way, in the configuration described in Patent Document 1 above, it is conceivable that the hook when not in use affects the appearance of the vehicle seat. <​​​​​​​​The headrest of the first embodiment includes a headrest body that supports the head of a vehicle occupant from the rear, a strap that is stored in the headrest body and pulled out from the headrest body, and a hook that is fixed to the strap and on which luggage is hung when pulled out from the headrest body together with the strap, and which is positioned along the lower part of the headrest body when the strap is stored in the headrest body.

[0007] In the first embodiment of the headrest, luggage can be hung on the hook when the hook is pulled out from the headrest body side together with the strap. When the strap is stored in the headrest body side, the hook is positioned along the bottom of the headrest body. This prevents the hook from being seen by the vehicle occupants when not in use. As a result, it is possible to prevent the unused hook from affecting the appearance of the vehicle seat.

[0008] The second embodiment of the headrest is characterized in that, in the first embodiment, a gripping portion is attached to the side of the hook opposite to the portion fixed to the strap, which is to be grasped by the occupants of the vehicle.

[0009] In the second embodiment of the headrest, the vehicle occupant can pull the hook out from the headrest body by pulling the gripping portion.

[0010] The third embodiment of the headrest is such that, in the first or second embodiment of the headrest, the strap is stored on the headrest body side, and the hook is attracted to the headrest body side by magnetic force.

[0011] In the third embodiment of the headrest, the strap is stored in the headrest body, and the hook is attracted to the headrest body by magnetic force. This suppresses vibration of the hook when not in use.

[0012] A fourth embodiment of a vehicle seat comprises a seat back that supports the back of a vehicle occupant from the rear, and a headrest of any one of the first to third embodiments supported on the upper part of the seat back, wherein the hook is positioned between the headrest body and the seat back with the strap stored on the headrest body side.

[0013] In the fourth embodiment of the vehicle seat, when the strap is stored in the headrest body, the hook is positioned along the lower part of the headrest body and between the headrest body and the seat back. This prevents the hook from being visible to the vehicle occupants when not in use. As a result, it is possible to prevent the unused hook from affecting the appearance of the vehicle seat. [Effects of the Invention]

[0014] The headrest and vehicle seat according to the present invention have the excellent effect of suppressing the impact of the hook on the appearance of the vehicle seat when not in use. [Brief explanation of the drawing]

Embodiments for Carrying out the Invention

[0016] The vehicle seat 10 according to an embodiment of the present invention will be described with reference to FIGS. 1 to 6. In the figures, the arrow FR indicates the front side of the seat, the arrow UP indicates the upper side of the seat, the arrow RH indicates the right side in the seat width direction, and the arrow LH indicates the left side in the seat width direction. Also, unless otherwise specified in the following description, when indicating the front and rear, up and down, and left and right directions, it shall indicate the front and rear in the seat front-rear direction, the up and down in the seat up-down direction, and the left and right in the seat width direction.

[0017] As shown in FIGS. 1 and 2, the vehicle seat 10 of the present embodiment includes a seat cushion (not shown) that supports the buttocks of the vehicle occupant from below, a seat back 12 that supports the back of the vehicle occupant from the rear side, and a headrest 14 that supports the head of the vehicle occupant from the rear side.

[0018] As shown in FIGS. 3 and 4, the headrest 14 includes a headrest stay 16 supported by the seat back 12 and a headrest main body 18 attached to the headrest stay 16. The headrest main body 18 includes a headrest pad 18B and a skin material 18B that covers most of the headrest pad 18B. Also, the headrest 14 includes a hook device 22 supported by the headrest stay 16 via a bracket 20.

[0019] As shown in FIG. 4, the headrest stay 16 is formed, for example, by bending a bar-shaped or cylindrical steel material. The headrest stay 16 includes a pair of left and right insertion portions 16A that are arranged at intervals in the left-right direction and extend in the up-down direction. The pair of left and right insertion portions 16A are configured to be supported in a state of being inserted into a headrest stay support portion (not shown) provided on the seat back 12 (see FIG. 1). Further, the headrest stay 16 includes a pair of left and right inclined portions 16B that extend obliquely forward from the upper ends of the pair of left and right insertion portions 16A toward the upper side. Furthermore, the headrest stay 16 includes a connecting portion 16C that connects the upper ends of the pair of left and right inclined portions 16B in the left-right direction. The shape of the connecting portion 16C when viewed from the front side is formed in a U shape with the lower side being open.

[0020] The bracket 20 is formed, for example, by performing press working or the like on a steel plate material. Both side portions in the left-right direction of the bracket 20 serve as joining portions 20A that are joined to the pair of left and right inclined portions 16B of the headrest stay 16 by welding. Also, the central portion in the left-right direction of the bracket 20 serves as a hook device attachment portion 20B that is offset downward with respect to the left and right joining portions 20A. A rectangular attachment hole 20C is formed in the hook device attachment portion 20B.

[0021] As shown in FIGS. 3, 4, 5, and 6, the hook device 22 includes a hook case 24 formed in a box shape and a spiral spring 26 supported by the hook case 24 within the hook case 24. The hook device 22 also includes a strap 28 formed in a belt shape, a hook 30 fixed to the strap 28, a gripping portion 32 fixed to the hook 30, and a plate 34 fixed to the hook case 24.

[0022] The hook case 24 is formed using a resin material as an example. In this embodiment, the hook case 24 has a split structure divided into two parts in the left-right direction. The hook case 24 includes a strap storage section 24A in which the strap 28 is stored, and a hook storage section 24B in which the hook 30 is stored.

[0023] The strap storage section 24A comprises an upper wall section 24C, a lower wall section 24D, a front wall section 24E, a rear wall section 24F, and a pair of left and right side wall sections 24G, which constitute the upper, lower, front, rear, and left and right sides of the strap storage section 24A, respectively. A space for storing the spiral spring 26 and the strap 28 is formed between the upper wall section 24C, the lower wall section 24D, the front wall section 24E, the rear wall section 24F, and the pair of left and right side wall sections 24G. The front wall section 24E and the rear wall section 24F are each provided with locking claws 24H that engage with the edges of the mounting holes 20C of the bracket 20. The hook case 24 is then attached to the bracket 20 by inserting the strap storage section 24A into the mounting holes 20C of the bracket 20 from below and engaging the locking claws 24H with the edges of the mounting holes 20C of the bracket 20. In other words, the hook device 22 is attached to the headrest stay 16 via a bracket 20. Furthermore, a pull-out hole 24J is formed in the boundary between the lower wall portion 24D and the rear wall portion 24F of the strap storage portion 24A, through which the strap 28 is pulled out.

[0024] The hook storage portion 24B protrudes rearward from the lower part of the rear wall portion 24F of the strap storage portion 24A and from the upper part relative to the pull-out hole 24J. A recess 24K for storing the hook 30 is formed in the lower part of the hook storage portion 24B. When the hook device 22 is attached to the headrest stay 16 via the bracket 20 and the headrest body portion 18 is attached to the headrest stay 16, as shown in Figure 3, the lower wall portion 24D of the strap storage portion 24A and the hook storage portion 24B are arranged along the lower part of the headrest body portion 18 and are exposed at the lower part of the headrest body portion 18.

[0025] As shown in Figures 5 and 6, the spiral spring 26 is formed by winding a strip-shaped steel plate in a spiral shape. The radially inner end of this spiral spring 26 is locked to a shaft member 36 whose axis is oriented in the left-right direction. This shaft member 36 is formed in the shape of a rod whose axis is oriented in the left-right direction. The shaft member 36 is fixed to the left and right pair of side wall portions 24G within the strap storage portion 24A, stretching between them. In this embodiment, the shaft member 36 is immobile relative to the left and right pair of side wall portions 24G.

[0026] The strap 28 is formed in a strip shape by weaving nylon or polyester threads, for example. One end of the strap 28 is locked to the radially outer end of the spiral spring 26. A stopper member 38 is fixed to the portion of the strap 28 adjacent to the portion locked to the spiral spring 26. As shown in Figure 5, the strap 28 is wound along the outer surface of the spiral spring 26 in the same direction as the spiral spring 26 is wound. As a result, most of the strap 28 is stored in the strap storage section 24A together with the spiral spring 26. The strap 28 can be pulled out to the outside of the strap storage section 24A through the pull-out hole 24J. The portion of the strap 28 to which the stopper member 38 is fixed is locked to the edge of the pull-out hole 24J, thereby restricting the pulling of the strap 28 out of the strap storage section 24A.

[0027] As shown in Figures 5 and 6, the hook 30 is formed, for example, using a resin material. The hook 30 comprises a strap fixing portion 30A fixed to the other end of the strap 28, and a luggage hanging portion 30B extending from the strap fixing portion 30A. The luggage hanging portion 30B is formed in a substantially J-shape, for example, capable of securing luggage (not shown). In addition, multiple magnets (two in this embodiment) are embedded and fixed to the luggage hanging portion 30B.

[0028] The gripping portion 32 is formed in a strip shape using the same material as the strap 28. This gripping portion 32 is fixed to the part of the luggage hanging portion 30B opposite to the strap fixing portion 30A. In this embodiment, the gripping portion 32 has an annular portion 32A into which a vehicle occupant can insert their finger.

[0029] The plate 34 is formed in a plate shape using a metal material such as steel. This plate 34 is fixed to the hook storage section 24B within a recess 24K formed in the hook storage section 24B.

[0030] (Operation and effects of this embodiment) Next, the operation and effects of this embodiment will be described.

[0031] As shown in Figures 2, 3, 4, and 5, in the embodiment described above, when most of the strap 28 is stored in the strap storage section 24A of the hook case 24, the hook 30 is stored in the recess 24K of the hook storage section 24B of the hook case 24. When the hook 30 is stored in the recess 24K of the hook storage section 24B of the hook case 24, the hook 30 is attracted toward the plate 34 side (headrest body 18 side) by the magnetic force of the magnet 40. This makes it possible to suppress vibration of the hook 30 when it is not in use.

[0032] Furthermore, when most of the strap 28 is stored in the strap storage section 24A of the hook case 24, and the hook 30 is stored in the recess 24K of the hook storage section 24B of the hook case 24, the hook 30 is positioned along the lower part of the headrest body 18 and between the headrest 14 and the seat back 12. This prevents the hook 30 from being visible to the vehicle occupants when not in use. As a result, it is possible to prevent the unused hook 30 from affecting the appearance of the vehicle seat 10.

[0033] Furthermore, when most of the strap 28 is stored in the strap storage section 24A of the hook case 24, and the hook 30 is stored in the recess 24K of the hook storage section 24B of the hook case 24, the gripping portion 32 extends rearward from between the headrest 14 and the seat back 12. Therefore, as shown in Figures 1 and 6, by pulling the gripping portion 32 rearward against the biasing force of the spiral spring 26, the vehicle occupant can pull the hook 30 out of the recess 24K of the hook storage section 24B of the hook case 24, and also pull the strap 28 out of the strap storage section 24A of the hook case 24. This allows the vehicle occupant to hang luggage on the luggage hanging portion 30B of the hook 30.

[0034] In this embodiment, an example has been described in which a gripping portion 32 is provided for gripping by the vehicle occupants, but the present invention is not limited thereto. Whether or not to provide a gripping portion 32 should be determined as appropriate, taking into consideration the impact of the gripping portion 32 on the appearance of the vehicle seat 10.

[0035] Furthermore, in this embodiment, an example was described in which the hook 30 is attracted to the headrest body 18 by magnetic force in order to suppress vibration of the hook 30 when not in use, but the present invention is not limited to this. For example, if vibration of the hook 30 is not a concern, the hook 30 may not be attracted to the headrest body 18 by magnetic force.

[0036] Although one embodiment of the present invention has been described above, it goes without saying that the present invention is not limited to the above, and can be implemented in various other ways without departing from the spirit of the invention. [Explanation of Symbols]
