  The present invention relates to a seat having a seat back and a headrest, and having a storage recess on the back surface of the seat back.

  As this type of sheet, there are, for example, Patent Document 1 and Patent Document 2. In Patent Document 1, the headrest is connected to the seat back so as to be rotatable between a use position located on the seat back and a storage position stored in the storage recess. That is, in Patent Document 1, a storage recess is provided to store the headrest. Therefore, in patent document 1, the coating | coated member which coat | covers the opening surface of an accommodation recessed part is not provided.

  On the other hand, in patent document 2, the accommodation recessed part is provided in order to accommodate accessories, such as a PET bottle and a magazine. Therefore, in patent document 2, in order to prevent the fall of the stored small article, it becomes the pocket shape by which the opening surface of the accommodation recessed part was coat | covered with the coating | coated member.

Japanese Patent Laid-Open No. 6-297899 JP 2002-238696 A

  In Patent Document 1, when the headrest is in the use position, the storage recess is just a color space and is wasted. Therefore, even when the headrest is in the use position, convenience can be improved if the storage space can be used as a pocket capable of storing small items. However, since Patent Document 1 does not include a covering member that covers the opening surface of the storage space, it cannot be used as a pocket. On the other hand, although it can utilize as a pocket in patent document 2, since the opening surface of an accommodation recessed part is always coat | covered with the coating | coated member, a headrest cannot be accommodated.

  Accordingly, the present invention solves the above-described problems, and an object of the present invention is to propose a seat in which a storage recess formed in a back surface of a seat back can be used for both storage of a headrest and storage of small items. .

  As a means for this, the present invention has a seat back and a headrest, a storage recess is provided in the back of the seat back, the use position where the headrest is located on the seat back, and the storage recess A seat member connected to the seat back so as to be rotatable between a seating position housed in the seat and a seat member capable of covering at least a lower part of an opening surface of the housing recess, the seat member and the headrest And a connecting member for interlocking with each other. In the present invention, the lower part of the opening surface means the lower half region of the opening surface. The covering member is flexible and is displaced between a covering state in which the opening surface of the storage recess is covered in a tensioned state and a retracted state in which the opening surface of the storage recess is fully opened in a slack state. Is possible. In addition, when the headrest is in the storage position, the covering member is in a retracted state, and when the headrest is rotated to the use position, the covering member is pulled upward by the connecting means, and the covering state is set. It is characterized by becoming.

  That is, when the headrest is in the retracted position, no traction force (tension) is applied to the covering member, and it is retracted in a slack state. When the headrest is rotated to the use position, the covering member is tensioned via the connecting member. By acting, it becomes a tense covering state. According to this, when the headrest is in the storage position, the opening surface of the storage recess is opened, so that the headrest can be stored in the storage recess without being obstructed by the covering member. On the other hand, when the headrest is rotated to the use position, the opening surface of the storage recess is covered with the covering member in conjunction with this, so that it can be used as a pocket for storing small items and convenience is improved.

  As a form in which the covering member and the headrest are interlocked by the connecting member, that is, a form in which the covering member is pulled by the connecting member as the headrest rotates, for example, the lower end of the connecting member is connected to the covering member. After being fixed to the upper end, the upper end of the connecting member can be fixed from the rotation center of the stay of the headrest to the rotation tip side.

  According to this, when the headrest is in the storage position, the upper end of the connecting member is below the rotation center of the stay of the headrest, so that no tension acts on the covering member. On the other hand, when the headrest is in the use position, the upper end of the connecting member comes above the center of rotation of the stay of the headrest, so that the covering member can be pulled to apply tension. In this way, the tension can be applied to the covering member by utilizing the change in the height position of the upper end fixing portion of the connecting member accompanying the rotation of the headrest.

  Further, as another form of pulling the covering member by the connecting member with the rotation of the headrest, for example, after fixing the lower end of the connecting member to the upper end of the covering member, the upper end of the connecting member is It is also possible to fix the turning trajectory of the stay of the headrest so that the upper end portion of the connecting member crosses the middle of the turning trajectory in which the headrest rotates from the storage position to the use position.

  According to this, the upper end portion of the connecting member crosses the rotation trajectory of the stay, but when the headrest is in the storage position, the stay and the connecting member do not interfere with each other. On the other hand, when the headrest is rotated from the storage position to the use position, the covering member is pushed in by the stay because the connecting member crosses the rotation trajectory of the stay in the middle portion. Thereby, a coating | coated member can be pulled by the lower end part of a connection member moving upwards.

  According to the present invention, the cover member is displaced between the cover state and the retracted state in conjunction with the rotation of the headrest, so that the storage recess formed in the back surface of the seat back can Can also be used for storage.

  Hereinafter, representative embodiments of the sheet according to the present invention will be described with reference to the drawings as appropriate.

Example 1
A first embodiment of the present invention will be described with reference to FIGS. The seat 1 is a seat for a vehicle such as an automobile, and includes a seat back 2 that serves as a backrest for the occupant, a headrest 3 that supports the occupant's head, and an unillustrated seat cushion that serves as a seat for the occupant. . A storage recess 10 is formed in the upper back of the seat back 2. Inside the seat back 2, a gate-shaped back frame 2a that forms the skeleton of the seat back 2 is provided. The headrest 3 has two left and right stays 4 protruding downward. The lower ends of both stays 4 are connected to the back frame 2a so as to be rotatable in the front-rear direction. Specifically, in the middle of the back frame 2a, a U-shaped bracket 20 in plan view is provided so as to be rotatable via left and right shaft pins 21, and the lower end of the stay 4 is joined to the inside of the bracket 20. ing. Therefore, the rotation center of the stay 4 and the headrest 3 that rotates integrally with the stay 4 is the shaft pin 21. In the upper part of the back surface of the seat back 2, vertically long grooves 5 that can receive the respective stays 4 are recessed in two places on the left and right. Each groove 5 extends from the upper surface of the seat back 2 to the upper surface of the storage recess 10. As a result, the headrest 3 can be rotated between the use position shown in FIG. 1A located on the seat back 2 and the storage position shown in FIG. ing. The storage recess 10 is formed in a size that can store at least the headrest 3.

  A rubber string 12, which is a long member having flexibility and stretchability, is routed on the opening surface of the storage recess 10 so as to reciprocate between the left and right side edges of the opening surface. Specifically, a plurality of insertion hooks 11 are vertically provided on the left and right side surfaces of the storage recess 10, and rubber strings 12 are sequentially inserted into the insertion hooks 11. The insertion hooks 11 are provided in a substantially lower half region of the opening surface, and the height positions of the left and right insertion hooks 11 are staggered. Thereby, at least the lower part of the opening surface can be covered with the rubber cord 12. The lowermost insertion hook 11 is provided facing the lower edge of the opening surface, and the lower end of the rubber cord 12 is fixed to the lowermost insertion hook 11 so that it cannot be detached. The rubber string 12 corresponds to the covering member of the present invention.

  The lower end of the non-stretchable cable 13 is connected to the upper end of the rubber cord 12 as a connecting member for interlocking the rubber cord 12 and the headrest 3. The cable 13 may be made of metal, synthetic resin, or natural material. The cable 13 is routed along the inner surface of the housing recess 10, and its upper end is fixed to the stay 4. Specifically, the upper end of the cable 13 is fixed to the rotation tip side (headrest 3 side) from the rotation center of the headrest 3. Reference numeral 14 denotes a holding plate that holds the cable 13 slidably along the inner surface of the housing recess 10. Reference numeral 15 denotes a fixing plate that fixes the upper end of the cable 13 at a certain height position. The total length of the rubber cord 12 and the cable 13 is designed to be slightly shorter than the total length of the routing route of the rubber cord 12 and the cable 13.

  Next, a usage pattern of the storage recess 10 will be described. As shown in FIG. 1A, when the headrest 3 is in the use position, the rubber cord 12 is in a covering state that covers the opening surface of the storage recess 10 in a tensioned state. Specifically, as shown in FIG. 2A, the upper end of the cable 13 is positioned above the rotation center (the shaft pin 21) of the headrest 3. And since the total length dimension of the rubber cord 12 and the cable 13 is slightly shorter than the total length of the routing route, the cable 13 is pulled upward and tension is applied to the rubber cord 12. As a result, the storage recess 10 functions as a pocket, and small articles W such as plastic bottles and magazines can be stored in the storage recess 10.

  On the other hand, when storing the headrest 3, after taking out the accessory W, as shown in FIG.1 (b), the headrest 3 is rotated back. Then, as shown in FIG. 2B, the upper end of the cable 13 moves downward from the rotation center of the headrest 3. Thereby, the tension | tensile_strength by the cable 13 is removed because a margin arises with respect to the full length of a routing path | route with the total length dimension of the rubber cord 12 and the cable 13. FIG. Then, as shown in FIG. 1 (c), the rubber string 12 is in a retracted state in which the opening surface of the storage recess 10 is fully opened while being slackened by its restoring force and its own weight, and is inhibited by the rubber string 12. The headrest 3 can be housed in the housing recess 10 without any problem. When the headrest 3 is rotated from the storage position to the use position again, the cable 13 is pulled upward and tension is applied to the rubber cord 12, so that the opening surface of the storage recess 10 is covered with the rubber cord 12. It becomes a pocket state.

(Example 2)
A second embodiment of the present invention will be described with reference to FIGS. The basic configuration of the second embodiment is the same as that of the first embodiment, and the seat back 2 having the storage recess 10 formed in the back surface, the use position located on the seat back 2 and the storage stored in the storage recess 10. And a headrest 3 connected to the seat back 2 so as to be rotatable between positions. A covering member that is reciprocated between the left and right edges of the opening surface of the housing recess 10 and that can cover at least the lower part of the opening surface; and a connecting member that interlocks the covering member and the headrest 3 The covering member is flexible, and is between a covering state in which the opening surface of the storage recess 10 is covered in a tensioned state and a retracted state in which the opening surface of the storage recess 10 is fully opened in a slack state. When the headrest 3 is in the retracted position, the covering member is in the retracted state. When the headrest 3 is rotated to the use position, the covering member is pulled upward by the connecting means to be in the covering state. Therefore, here, the difference from the first embodiment will be mainly described.

  In the second embodiment, a non-stretchable belt 16 is routed instead of the rubber cord 12 and the cable 13 of the first embodiment. The belt belt 16 is routed from the lower edge of the storage recess 10 to the stay 4, and the lower end portion functions as a covering member and the upper end portion functions as a connecting member. That is, in the second embodiment, a series of long members serving both as a covering member and a connecting member are used. The lower end of the belt belt 16 is fixed to the lowermost insertion hook 11 so as not to be detached as in the first embodiment, but the belt belt 16 is allowed to slide up and down at the folded portion. A guide 25 having a vertically long slot 25a is provided. The long hole 25a is formed from the upper and lower intermediate positions of the storage recess 10 to the lower end.

  An upper end portion (a portion functioning as a connecting member) of the belt belt 16 is routed inside the seat back 2. Therefore, a member like the holding plate 14 of Example 1 is not provided. In addition, the upper end of the belt belt 16 is fixed so that the upper end portion of the belt belt 16 crosses the rotation locus of the left and right stays 4 in the middle of the rotation locus where the headrest 3 rotates from the storage position to the use position. ing. The tip of the belt 16 may be fixed to the back frame 2a built in the seat back 2 or the back pad 2b as a cushioning material by bonding or the like. Therefore, there is no member like the fixing plate 15 of the first embodiment. The upper end portion of the belt belt 16 crosses the rotation locus of the stay 4 above the rotation center of the headrest 3. The length of the belt belt 16 is designed to be slightly longer than the entire length of the routing path.

  Next, the usage form of the storage recessed part 10 in Example 2 is demonstrated. As shown in FIG. 3A, when the headrest 3 is in the use position, the lower end portion of the belt belt 16 is in a covering state that covers the opening surface of the storage recess 10 in a tensioned state. Specifically, as shown in FIG. 4A, the upper end portion of the belt belt 16 is arranged so as to cross the rotational miracle of the stay 4, so that the upper end portion of the belt belt 16 is aligned with the left and right stays 4. Is pushed into the back of the groove 5. As a result, the belt belt 16 is pulled as a whole and is in a covered state in which tension is applied, and the storage recess 10 can be used as a pocket. In addition, since the belt belt 16 having a certain area (width dimension) is used, the opening surface can be covered in a wider range than the rubber cord 12 of the first embodiment.

  On the other hand, when the headrest 3 is rotated backward to store the headrest 3, the stay 4 moves downward from the center of rotation of the stay 4 as shown in FIG. Separate from the belt 16. Then, as shown in FIG. 3B, the belt belt 16 is lowered downward as a whole by its own weight, so that the lower end of the belt belt 16 is slackened. In addition, the folded portion of the belt belt 16 also slides downward along the long hole 25 a of the guide 25. Thereby, it will be in the retreat state which opens the opening surface of the storage recessed part 10 in the state which the lower end part of the belt belt 16 slackened. Thus, the headrest 3 can be housed in the housing recess 10 without being obstructed by the belt belt 16.

  When the headrest 3 is rotated again from the storage position to the use position, the belt belt 16 is routed in the middle of the rotation locus of the stay 4 in this direction, so that the upper end of the belt belt 16 is in the groove 5. It is pushed into the back. At this time, since the belt belt 16 has a certain area (width dimension), it can be accurately pushed by the stay 4. As a result, tension is applied to the belt belt 16, and the folded portion slides upward along the long hole 25 a of the guide 25, so that the opening surface of the storage recess 10 is in a pocket state covered with the belt belt 16. . The other parts are the same as those in the first embodiment, and the same members are denoted by the same reference numerals and the description thereof is omitted.

(Example 3)
Embodiment 3 of the present invention will be described with reference to FIG. Since the basic configuration of the third embodiment is the same as that of the first embodiment, differences from the first embodiment will be mainly described. In the third embodiment, the covering cloth 18 having the head bar 17 at the upper end edge is used as the covering member. A cylindrical portion that is open at both the left and right ends is formed at the upper edge of the covering cloth 18, and a head bar 17 having a certain rigidity is inserted through the cylindrical portion. The head bar 17 is longer than the width dimension of the covering cloth 18. Guide grooves 26 extending from the upper and lower intermediate positions to the lower end are respectively formed in the left and right side surfaces of the storage recess 10, and the left and right ends of the head bar 17 are fitted to the left and right guide grooves 26 so as to be slidable in the vertical direction. ing. The lower edge of the covering cloth 18 is sewn to the lower edge of the storage recess 10. Further, urging rubbers 19 that constantly urge the head bar 17 and the covering cloth 18 downward are connected to the left and right ends of the head bar 17. The lower end of the urging rubber 19 is fixed to the lower surface of the storage recess 10. Further, the same cable 13 as that of the first embodiment is provided at both left and right end portions of the head bar 17 as a connecting member for interlocking the covering cloth 18 and the headrest 3. Both the left and right cables 13 are fixed to the stay 4 in the same manner as in the first embodiment. Although not shown, also in the third embodiment, the cable 13 is held by the holding plate 14.

  Next, a usage pattern of the storage recess 10 will be described. As shown in FIG. 5A, when the headrest 3 is in the use position, the upper end of the cable 13 is positioned above the rotation center of the headrest 3, so that the covering cloth 18 is in a tensioned state in the storage recess. 10 opening surfaces are covered. On the other hand, when the headrest 3 is rotated backward to accommodate the headrest 3, the upper end of the cable 13 moves downward from the center of rotation of the headrest 3 as shown in FIG. Then, the head bar 17 slides downward along the left and right guide grooves 26 by the urging force of the urging rubber 19, so that the opening surface of the storage recess 10 is opened almost entirely with the covering cloth 18 slackened. To do. Thereby, the headrest 3 can be stored in the storage recess 10 without being obstructed by the covering cloth 18 or the head bar 17. When the headrest 3 is rotated again from the storage position to the use position, the cable 13 is pulled upward accordingly, so that the head bar 17 moves upward in the guide groove 26 against the urging force of the urging rubber 19. To slide. As a result, a tension is applied to the covering cloth 18, and a pocket state is formed in which the opening surface of the storage recess 10 is covered. The other parts are the same as those in the first embodiment, and the same members are denoted by the same reference numerals and the description thereof is omitted.

(Modification)
As mentioned above, although typical embodiment of this invention was described, it is not restricted to this, A various deformation | transformation is possible in the range which does not deviate from the summary of this invention. For example, also in Example 2, the rubber string 12 and the cable 13 as in Example 1 can be used. Conversely, also in the first embodiment, the belt belt 16 as in the second embodiment can be used. A belt belt having elasticity can also be used at the lower end of the belt belt 16. When using a long member having stretchability as the covering member, it may have stretchability in all of them, or by connecting a stretchable member and a non-stretchable member, It may have elasticity. In the third embodiment, the upper end of the cable 13 can be fixed in the same manner as the second embodiment.

  Moreover, a non-stretchable string member as a whole can be used as the covering member. In this case, as in Modification 1 shown in FIG. 6, the folded portion of the string member 27 is inserted into the ring 28, and the ring 28 is made of a rubber member or the like whose both ends are fixed to the inner surface of the storage recess 10. What is necessary is just to insert the elastic body 29. FIG. In this case, when the headrest 3 is in the use position, as shown in FIG. 6A, tension is applied to the string member 27, so that the folded portion of the ring 28 and the string member 27 causes the urging force of the elastic body 29. It is located above against. On the other hand, when the headrest 3 is rotated to the storage position, the tension on the string member 27 is removed, so that the ring 28 and the folded portion of the string member 27 are moved downward by the urging force of the elastic body 29 to open the opening. The surface can be opened almost entirely.

  Moreover, when using the string member 27, the form like the modification 2 shown in FIG. 7 is also employable. Specifically, a guide 30 having a long hole 30a extending obliquely in the up-down direction is provided at the folded portion of the string member 27, and the string member 27 is slidably inserted through the long hole 30a. In this case, it is preferable to connect an elastic body 31 made of a rubber member or the like that constantly biases the folded portion of the string member 27 in the vicinity of the folded portion of the string member 27. In this case, when the headrest 3 is in the use position, as shown in FIG. 7A, tension is applied to the string member 27 so that the folded portion of the string member 27 resists the urging force of the elastic body 31. The guide 30 is located at the upper end of the long hole 30a. On the other hand, when the headrest 3 is rotated to the storage position, the tension on the string member 27 is removed, so that the folded portion of the string member 27 moves downward in the long hole 31a by the urging force of the elastic body 31. The opening surface can be opened almost entirely.

  Further, when the belt belt 16 is used as the covering member as in the second embodiment, the upper end portion of the long hole 25a of the guide 25 is arranged in the routing direction of the belt belt 16 as in the third modification shown in FIG. It is preferable to incline in the direction perpendicular to the direction. According to this, the belt belt 16 having a certain width can be neatly routed without causing wrinkles or twists. In Example 2 and Modification 3, it is also preferable to connect an elastic body made of a rubber member or the like that constantly biases the folded portion of the belt belt 16 in the vicinity of the folded portion of the belt belt 16.

  Moreover, when using the elongate rubber string 12 which has elasticity as a coating | coated member like Example 1, inside the cylindrical cover 32 which has a fixed width dimension like the modification 4 shown in FIG. It is also possible to insert a rubber string 12 into a belt shape.

  Further, as in the second embodiment, the upper end portion of the belt belt 16 as the connecting member is crossed the rotation locus of the stay 4 in the middle portion of the rotation locus where the headrest 3 is rotated from the storage position to the use position. In the case of routing, it is preferable to provide a guide band 33 between the left and right grooves 5 and insert the band belt 16 through the guide band 33 as in Modification 5 shown in FIG. The guide band 33 is a flat plate member having a certain level of strength, such as leather, cloth, or synthetic resin, and has a vertically long cut 34 formed on both left and right sides. In addition, the belt belt 16 is inserted from the front surface side of the guide belt 33 through the one cut 34 to the back surface side, and is inserted through the other cut 34 from the back surface side to the front surface side. According to this, the sliding of the belt belt 16 can be stabilized.
