JP 2007-331400 A JP 2004-141409 A

  By the way, in recent years, in a vehicle in which a luggage compartment is disposed behind a rear seat, such as a station wagon, a large luggage or a long luggage (hereinafter, referred to as the rear seat) There is a tendency to prefer a so-called trunk-through structure that allows a long object or the like to be loaded in a luggage compartment.

  Here, looking at Patent Document 1, the armrest stored in the front portion of the seat back of the central seat is configured to be able to be moved forward, but the seat back is not capable of being moved forward. For this reason, in the case of the above-mentioned Patent Document 1, it is difficult to load a long object or the like extending from the cargo compartment to the rear seat in the vehicle, and the usability of the cargo compartment is significantly reduced.

  Moreover, when the armrest is moved forward on the seat cushion as in Patent Document 1, there is a problem that the height of the armrest cannot be sufficiently secured.

  Furthermore, in the said patent document 1, since it has the structure where the said armrest is stored in the front part of the seat back of a center seat, there exists a problem that thickness of an armrest cannot fully be ensured. Therefore, when the armrest is moved forward and placed at the use position, the height is inevitably lowered.

  In this way, if the height when the armrest is placed at the use position is not sufficient, the distance from the passenger's shoulder to the armrest's elbow rest surface will be long, and the passenger will feel uncomfortable when the elbow is placed on the armrest. There is a risk of burden.

  Therefore, in the above-mentioned Patent Document 1, in view of the above-described problems, a lift portion attached to the armrest body so as to be movable up and down is provided, and the height of the elbow rest surface is secured by raising the lift portion. I have to.

  However, since the height of the armrest body cannot be set high for the reasons described above, there is a limit to the height even if an attempt is made to secure the height by providing a lift portion.

  On the other hand, in the prior art disclosed in Patent Document 2, trunk-through can be realized by providing the seat back of the central seat on the seat cushion so as to be able to fall forward as described above. However, since the back portion when the seat back is moved forward on the seat cushion is used as an armrest, there is still a problem that the height of the elbow rest surface cannot be sufficiently secured.

  Therefore, in recent years, a second hinge shaft is provided in the middle of the seat back separately from the hinge shaft for moving the seat back forward, and the seat back of the seat back is rotated by the second hinge shaft as a center. There has been proposed one in which only the upper part is moved forward and this is used as an armrest.

  With such a configuration, the seatback is bent in the middle of the seatback and moved forward, so that the lower portion of the seatback becomes a leg portion having a vertical width, and as a result, the upper portion of the seatback used as an armrest is It can be installed at a high position spaced upward from the seat cushion.

  However, in this case, if the upper part of the seat back is tilted forward with the second hinge shaft as the center of rotation, the upper end becomes a free end that is not supported by any one, and the upper part of the seat back is cantilevered. It becomes the state of.

  Therefore, in order to stably support the occupant's elbow, the support rigidity of the second hinge shaft must be set high, and as a result, the weight of the seat and the configuration become complicated. .

  SUMMARY OF THE INVENTION An object of the present invention is to provide a vehicle seat device capable of ensuring a sufficient height and supporting rigidity in an armrest while improving usability of a luggage compartment disposed at the rear.

FIGS. 1 to 5 show a state in which the armrest 24 is in a use position disposed above the back surface portion 21a in a forward-turned state in which the seatback 21 is forward-fallen on the seat cushion 10. When the armrest 24 is in the use position, the front portion of the armrest 24 is supported by the hinge shaft 25 while the rear portion is in contact with and supported by the back surface portion 21a.

  In addition, the member shown with the code | symbol 8 in FIG. 5 is the front seat arrange | positioned ahead of the rear seat 1, and comprises a driver's seat or a passenger seat. And the member shown with the code | symbol 9 is the wheel house for rear wheels formed in the both sides of the luggage compartment 2a.

  As described above, when the armrest 24 is in the use position, the upper-side elbow rest surface 24a is disposed at a position higher than the back surface portion 21a of the seat back 21, and is indicated by a two-dot chain line in FIGS. The occupant X seated on the right seat 1R can place his / her left elbow Xel on the elbow rest surface 24a.

  However, the armrest 24 in use is positioned at the substantially central portion of the seat back 21 in the vehicle width direction, and thus the right elbow of the occupant seated on the left seat 1L can be put in the same manner.

  In the state where the armrest 24 is disposed at the use position, the elbow rest surface 24a is configured to extend in a substantially horizontal direction as shown in FIG. 1 and can support the arm of the occupant X in a substantially straight posture. ing.

  Moreover, in the seat back 21, as shown in FIGS. 1-4, the recessed part 26 dented toward the front side is formed in a part of back part 21a. 4 are attached to the side wall portions 26a and 26a on both sides in the vehicle width direction of the recessed portion 26, and the hinge shafts 25 and 25 described above are attached to the recessed portions 26 and 27a, respectively. The bearings 27 and 27 are supported at predetermined positions.

  Also, as shown in FIG. 1, from the bottom surface portion 26b of the recessed portion 26, the lower end side of the seat back 21 (in this case, the lower end side when the seat back 21 is in the upright state, A retreating portion 26d having a circular arc cross section is formed over the side wall portion 26c. The retracting portion 26d is formed along a locus α (a line indicated by a one-dot chain line in FIG. 1) of the end portion 24b when the armrest 24 is rotated about the hinge shaft 25.

  Further, on the side wall portion 26e on the upper end side of the seat back 21 of the recessed portion 26 (in this case, the upper end side when the seat back 21 is in the upright state, and the front end side in the forwardly tilted state). As shown in FIGS. 1 to 3, a plate-shaped cup holder 28 in which a plurality (two in this case) of positioning holes 28a and 28a are formed is provided.

  The cup holder 28 is rotatably supported via the hinge shafts 29, 29, and extends substantially horizontally in front of the armrest 24 as shown in FIGS. And the side wall portion 26e on the upper end side of the seat back 21 (in this case, the upper end side when the seat back 21 is in the upright state and the front end side in the forward-turned state). It is supported so as to be movable between the storage (non-use) position stored in the second recessed portion 26f formed in the above.

  And the cup holder 28 is always urged | biased toward the use position by the elastic member not shown with which the hinge shafts 29 and 29 were equipped, for example. For this reason, when an external force does not act on the cup holder 28, the cup CU such as a drinking water container indicated by a two-dot chain line in FIG. 1 is fitted into the positioning hole 28a, thereby positioning the cup CU at the front position of the armrest 24. It can be held.

  Further, in the recessed portion 26, the side wall portion 26e on the upper end side of the seat back 21 is formed with a second recessed portion 26f that is recessed toward the upper end portion. As shown in FIGS. 1 and 3, the cup holder 28 is disposed on both sides in the vehicle width direction corresponding to the position of the second recessed portion 26 f.

  6-8 is a figure which shows the state when the armrest 24 has been arrange | positioned in the retracted position under the front-down state of the seat back 21 of the center seat 1C, FIG. 6 is a sectional side view, FIG. FIG. 8 is a perspective view showing the central seat 1C, and FIG. 8 is a view seen from the luggage compartment 2a side. In the present embodiment, when the armrest 24 in the state where it is disposed at the use position shown in FIGS. 1 to 5 is rotated around the hinge shaft 25, both side ends 24b and 24c of the armrest 24 in the vehicle front-rear direction are Each of them is stored in the storage position in the recessed portion 26 as shown in FIGS. 6 to 8 while drawing the trajectories α and β shown by alternate long and short dash lines in FIG.

  At this time, since the recessed portion 26 has the arc-shaped retracting portion 26d described above, the interference between the end portion 24b and the bottom surface portion 26b of the recessed portion 26 is avoided, and the armrest 24 is made smooth. Can be rotated.

  In this way, when the armrest 24 is stored, the elbow rest surface 24a of the armrest 24 is directed from above the back surface portion 21a of the seat back 21 at the use position, and the bottom surface portion of the recessed portion 26 at the storage position. The direction is reversed so as to be directed to 26b, and the back surface portion 24d opposite to the elbow rest surface 24a becomes the upper surface portion and is exposed to the back surface portion 21a side.

  Further, when the armrest 24 is stored in the recessed portion 26, the position of the end portion 24 b substantially coincides with the side wall portion 26 c of the recessed portion 26, while the position of the end portion 24 c is the side wall portion of the recessed portion 26. 26e.

  Thereby, in this embodiment, when the armrest 24 is disposed at the storage position, the back surface portion 24d forms a surface substantially continuous with the back surface portion 21a of the seat back 21. Therefore, in the trunk through state, as shown in FIGS. 6 and 8, the back portions 21a and 24d of the seat back 21 and the armrest 24 and the trunk board 7 of the luggage compartment 2a are substantially flush with each other.

  Therefore, in the trunk through state, a floor surface that extends from the cargo compartment 2a to the rear seat 1 in front of the vehicle is formed, and a long object L as shown by a two-dot chain line in FIGS. Large luggage can be loaded in the luggage compartment 2a.

  Further, in the present embodiment, the width of the armrest 24 in the vehicle width direction is set so as to substantially match the distance between the side wall portions 26a, 26a of the recessed portion 26. Therefore, when the armrest 24 is in the retracted position, the armrest 24 is held in the retracted position by friction with the side wall portions 26a, 26c, and 26e of the recessed portion 26, and the seat back 21 is in the forward-turned state. Even if the armrest 24 is switched from the standing position to the standing position, the armrest 24 is held in a predetermined storage position without jumping out to the cargo compartment 2a side.

  By the way, when the armrest 24 is in the use position, the cup holder 28 is located within the rotation range of the armrest 24 (refers to an area between the trajectories α and β) as shown in FIG. For this reason, when the armrest 24 is rotated from the use position toward the retracted position, the elbow rest surface 24a of the armrest 24 comes into contact with the cup holder 28 along the way. When the armrest 24 is further rotated, the armrest 24 finally reaches the storage position while pushing the cup holder 28 against the elastic force of the elastic member.

  At this time, the cup holder 28 is rotated toward the second recessed portion 26f by the pressing force of the elbow rest surface 24a of the armrest 24, and when the armrest 24 is stored in the recessed portion 26, it is shown in FIG. Thus, the cup holder 28 is interlocked and stored in the second recessed portion 26f.

  Although not shown in FIGS. 1 to 5, an annular operating string 30 as shown in FIGS. 6 to 8 is attached to the back surface portion 24 d of the armrest 24. The operation string 30 is located on the upper end side of the seat back 21 with respect to the hinge shaft 25 when the armrest 24 is in the retracted position.

  Here, when moving the armrest 24 from the retracted position to the use position, the occupant first grasps the operation string 30 and pulls out the end 24 c of the armrest 24 to project it above the recessed portion 26. Then, by gripping the protruding end portion 24c and rotating the armrest 24, the direction of the elbow rest surface 24a is directed from the bottom surface of the recessed portion 26 to above the back surface portion 21a of the seat back 21. Can be reversed so as to be oriented.

  At this time, the cup holder 28 is moved from the non-use position shown in FIG. 5 to the use position shown in FIG. 1 by the elastic force of the elastic member provided on the hinge shaft 29 in conjunction with the rotation of the armrest 24. It is rotated toward it and returned to the use position.

  However, the present invention is not necessarily limited to this. For example, “PUSH as shown by a two-dot chain line in FIG. 7 on the end portion 24b side of the rear surface portion 24d of the armrest 24 from the hinge shaft 25 side. May be provided, and the arm rest 24 may be forcibly rotated to project the end portion 24c by pressing the instruction portion 30 '.

  As described above, in the present embodiment, the armrest 24 is provided on the back surface portion 21a of the seat back 21, and when the seat back 21 is brought forward, the arm rest 24 is disposed above the back surface portion 21a, and the seat back Since the armrest 24 is supported so as to be movable between the storage positions stored in the recessed portions 26 of the 21, the height of the elbow rest surface 24 a can be sufficiently secured at the use position of the armrest 24.

  For this reason, as shown in FIGS. 1 and 5, when the occupant X is seated, the distance from the occupant's shoulder Xs to the armrest 24a of the armrest 24 can be shortened. It is possible to reduce the uncomfortable feeling and burden when placing the elbow Xel.

  In the forward-turned state of the seat back 21, the armrest 24 can be stored in the recessed portion 26, whereby a trunk-through state in which the floor surface continues from the luggage compartment 2 a to the rear seat 1 can be achieved. For this reason, it is possible to load a long object L as shown in FIGS. 6 and 8, a large luggage, or the like in the luggage compartment 2 a, and to improve the usability of the luggage compartment 2 a.

  Further, when the armrest 24 is in the use position, the front portion thereof is supported by the hinge shaft 25, while the rear portion is supported by the back surface portion 21a of the seat back 21, so that the armrest can be provided without providing any special support means. 24 support rigidity can be secured. For this reason, the complexity and weight of the structure of the center sheet 1C can be suppressed.

  In addition, since the recessed portion 26 is provided on the back surface portion 21a of the seat back 21, the recessed portion 26 becomes an empty space when the armrest 24 is in the use position. be able to.

  Further, the armrest 24 is disposed on the seat back 21 of the central seat 1C provided between the left and right seats 1R and 1L as shown in FIG. 2 and the like, so that the armrest 24 is seated on the left and right seats 1R and 1L. It can be used as an armrest 24 for the occupant X.

  Further, the armrest 24 is supported so as to be pivotable in the vehicle front-rear direction via the hinge shaft 25, and the elbow rest surface 24a of the armrest 24 is directed above the back surface portion 21 in the use position, while being recessed in the retracted position. Since the direction can be reversed so as to face the bottom surface portion 26b of the installation portion 26, the elbow rest surface 24a can be exposed only when in the use position, in other words, when the armrest 24 is in the retracted position. 6 to 8, the elbow rest surface 24a can be concealed. For this reason, in the standing state etc. of the seat back 21 which does not use the armrest 24, the dirt and damage of the elbow rest surface 24a resulting from contact with other articles | goods etc. can be prevented reliably.

  When the armrest 24 is configured to be pivotably supported in the vehicle front-rear direction as in the present embodiment, the armrest 24 is inadvertently rotated by the occupant X putting his weight on the front side of the elbow Xel. In order not to move, the position of the hinge shaft 25 is set to the front side as much as possible in the forward-turned state of the seat back 21, that is, the upper end side of the seat back 21, so that the end 24b and the hinge shaft 25 It is preferable to shorten the distance.

  In addition, the occupant X can place the elbow Xel without a sense of incongruity by holding the elbow rest surface 24a of the armrest 24 substantially horizontally when it is in the use position.

  Further, when the armrest 24 is disposed in the retracted position in the forward-turned state of the seat back 21, the back surface portion 21a and the trunk board 7 of the luggage compartment 2a are substantially flush with each other, so that the level difference between the two can be kept small. This can reduce the burden of lifting and lowering the long object L or the like. Therefore, taking in and out the long object L and the like can be facilitated.

  Further, a cup holder 28 is provided on the side wall portion 26e at the front end portion of the recessed portion 26, and the use position that is held substantially horizontally in the forward-turned state of the seat back 21 and the storage position that is stored in the second recessed portion 26f When the armrest 24 is in the use position, the cup holder 28 can be disposed near the front of the occupant X with the elbow Xel placed on the elbow rest surface 24a. . For this reason, access to the cup CU is facilitated, and usability can be improved.

  Further, the cup holder 28 is held in the use position by the elastic member when the armrest 24 is in the use state, and uses the pressing force when the armrest 24 is rotated when the armrest 24 is stored. Thus, the cup holder 28 can be stored in the second recessed portion 26f in conjunction with the storage of the armrest 24 by being stored in the second recessed portion 26f. For this reason, it is not necessary for the occupant X to directly operate the cup holder, and the work effort can be reduced.

  In addition, when the armrest 24 is in the retracted position, friction is generated between the side wall portions 26a, 26c, 26e and the armrest 24, so that the side wall portions 26a, 26c, 26e It can be said that it has a function as a holding means for holding in position.

  Thereby, even if the seat back 21 is in the upright state, the armrest 24 can be held in the retracted position, and the armrest 24 can be prevented from becoming an obstacle when a load is loaded on the trunk board 7 of the luggage compartment 2a. Further, by preventing the armrest 24 from jumping out, there is also an advantage that the appearance from the rear of the vehicle can be secured.

  In this case, it is not necessary to separately provide a lock mechanism as a holding means for holding the armrest 24 in the storage position and a release mechanism for releasing the holding by the lock mechanism. For this reason, it is possible to hold the armrest 24 and to release the holding while having a simple configuration, and it is possible to suppress the complexity and weight of the structure of the central seat 1C.

  Further, when the armrest 24 is in the retracted position when the seat back 21 is in the retracted position, the operation string 30 is provided on the back surface portion 24d, which is the upper surface, so that when the armrest 24 is moved from the stored position to the use position, The armrest 24 can be easily rotated by the operation 30.
