Description

  The present invention relates to an armrest for a vehicle seat and a vehicle seat, and more particularly, an armrest provided in the vehicle seat and having an inclination on a mounting surface on which a seated person places an arm, and such an armrest. Relates to a vehicle seat.

  In the vehicle seat, an armrest is provided on the side of the seating portion. In this type of armrest, as shown in Patent Document 1, for example, the upper surface on which a seated person places his arm is often configured as a flat surface.

JP 2013-1292 A

  When the width of the armrest becomes narrow due to restrictions on the space in which the vehicle seat can be installed, if the upper surface is flat, the seated person may not be able to comfortably place the arm. In particular, when only one armrest is provided between a plurality of adjacent seats, such as an aircraft seat, seats on both sides put their arms on the armrest at the same time without bringing the elbows etc. into contact with each other. It is difficult to place. Moreover, both seated persons on both sides often hesitate to use armrests.

  SUMMARY OF THE INVENTION The problem to be solved by the present invention is to provide an armrest for a vehicle seat that allows a seated person sitting on the vehicle seat to comfortably place the arm even if the width of the armrest is limited, and such an armrest. It is providing the vehicle seat provided with.

  In order to solve the above problems, an armrest for a vehicle seat according to the present invention is a plane that descends toward the side facing the seating portion on the upper surface of the armrest attached to the side of the seating portion of the vehicle seat. The gist of the present invention is to have a curved or downwardly convex mounting surface.

  Here, the armrest may have two mounting surfaces described above, and the two mounting surfaces may be lowered toward both sides in the width direction.

  In this case, the armrest has a support portion and two rotating portions, and the two rotating portions each have a first surface and a second surface, and the length of the armrest is long. As described above, the first surface is supported in the first rotation state so as to be independently rotatable between a first rotation state and a second rotation state around a direction axis. The second surface is preferably a flat surface and is exposed upward in the second rotation state.

  The placement surface may be provided over the entire length of the armrest.

  The placement surface described above is a downwardly convex curved surface, and an elbow placement portion whose depth of the downward convex shape is larger than that of other portions is in a position where the elbow of the seated person seated on the seating portion comes into contact. And the depth of the downwardly convex shape is preferably smaller toward the front in the longitudinal direction than the elbow rest.

  In this case, the armrest may have the widest width in the elbow rest, and the width may be narrower toward the front in the longitudinal direction than the elbow rest.

  The gist of the vehicle seat according to the present invention includes the armrest as described above.

  The armrest of the vehicle seat according to the above invention has a flat or downward convex curved mounting surface on the upper surface, which is lowered toward the side facing the seating portion when attached to the vehicle seat. . Therefore, the area of the upper surface can be increased compared to the case where the upper surface is made of a flat surface having substantially no inclination. As a result, even when the width at which the armrest can be installed is narrow, the area of the area where the seated person seated on the seating section can place the arm increases, and the arm can be placed comfortably. In particular, when the placement surface is formed in a downwardly convex curved shape, the curved shape is along the arm, so that the arm can be supported by contacting the arm of the seated person in a large area.

  Here, when the armrest has two placement surfaces and the two placement surfaces are respectively lowered toward the both sides in the width direction, the two armrests are disposed between two adjacent seating portions. When the armrest is installed, each seated person sitting next to each other can place his / her arm on the placement surface facing the person. The possibility of the seated elbows on both sides touching each other is also reduced. Also, between the two mounting surfaces becomes the top of the upper surface of the armrest, and the two mounting surfaces partitioned by the top are lowered toward the respective seating portions, so that the armrest It can be visually recognized that it should be shared. As a result, it becomes easy to prevent the seat occupants on both sides from hesitating to use the arm rest and to prevent one seat occupant from monopolizing the arm rest.

  In this case, the armrest has a support portion and two rotating portions, each of the two rotating portions has a first surface and a second surface, and the armrest has a longitudinal axis. The periphery is supported by the support portion so as to be independently rotatable between the first rotation state and the second rotation state, and the first surface becomes a mounting surface in the first rotation state, and the second surface According to the structure which consists of a plane and is exposed upwards in the 2nd rotation state, by arrange | positioning each rotation part in a 1st rotation state, the 1st surface which descend | falls to the seated person side is made into an armrest. Can be used as On the other hand, if each rotation part is arrange | positioned in a 2nd rotation state, the flat 2nd surface exposed upwards can be utilized as an armrest of another form, or a table.

  When the placement surface is provided in the entire longitudinal direction of the armrest, the seated person can easily place a wide region of the forearm portion on the placement surface. Moreover, the shape of the whole armrest becomes simple and it is easy to manufacture by extrusion molding or the like.

  The mounting surface is a downwardly convex curved surface, and has an elbow mounting portion where the depth of the downwardly convex shape is larger than other portions at the position where the elbow of the seated person sitting on the seating portion comes into contact When the depth of the downward convex shape is smaller toward the front in the longitudinal direction than the elbow placing portion, the seated person can comfortably place the elbow on the elbow placing portion. Therefore, the entire armrest can be formed short while ensuring comfort for the seated person, and space saving and weight reduction of the armrest can be achieved.

  In this case, according to the configuration in which the armrest has the widest width in the elbow placement portion and becomes narrower in the longitudinal direction than the elbow placement portion, the elbow rest for the seated person is reduced. Since the width of the part ahead of the elbow placement portion can be narrowed while securing the placement comfort, the armrest can be further reduced in space and weight.

  Since the vehicle seat according to the invention includes the armrest as described above, the seated person sitting on the seating portion can comfortably sit on the armrest mounting surface even when the width in which the armrest can be installed is limited. Can be placed.

  Hereinafter, an armrest of a vehicle seat and a vehicle seat according to an embodiment of the present invention will be described in detail with reference to the drawings.

[Vehicle seat]
FIG. 1 shows an outline of a vehicle seat (sometimes referred to simply as a sheet in the present specification) 1 according to an embodiment of the present invention. The vehicle seat 1 is mainly installed in an aircraft, a railway vehicle, or the like, and a plurality of seating portions 2 each having a seat cushion 2a and a seat back 2b are provided adjacent to each other.

  An armrest is provided between the adjacent seating portions 2. The armrest is according to any of the embodiments of the present invention, and FIG. 1 shows a form in which an armrest 10 according to a first embodiment of the present invention described below is provided. Only one armrest 10 is provided between two adjacent seating portions 2 and 2 so as to protrude forward from a portion between two adjacent seat backs 2b and 2b. . The armrest 10 is coupled to the frame of the seating portions 2 and 2 at the rear end portion so as to be rotatable in the front-rear direction. In the state of rotating forward, the longitudinal direction is substantially in the front-rear direction as shown in FIG. In a state where it is rotated rearward and flipped up, the longitudinal direction is substantially in the vertical direction.

  In the vehicle seat 1 shown in FIG. 1, the armrest 10 is provided at a portion between the plurality of seating portions 2 and 2 provided adjacent to each other. What is necessary is just to comprise the armrest 10 in the side of a seating part, and to comprise a vehicle seat. For example, the same armrest 10 can be provided outside the seating portions 2 at both ends among the plurality of seating portions 2 provided adjacent to each other. Moreover, the same armrest 10 can be provided in the one or both sides of the seating part independent of the other seating parts.

[Armrest according to the first embodiment]
Next, a vehicle seat armrest (sometimes referred to simply as an armrest in this specification) 10 according to a first embodiment of the present invention will be described with reference to FIGS. Here, the structure of the armrest 10 will be described with reference to the direction in a state where the armrest 10 is attached to the vehicle seat 1. That is, as shown in FIG. 1, the width direction X, the front-rear direction (longitudinal direction) Y, and the up-down direction Z are defined on the basis of the state of being attached to the vehicle seat 1 and rotated forward. Moreover, let the direction which goes to the width direction center part of each armrest 10 be width direction inner side.

  The armrest 10 has an armrest frame 12 and an arm cap 11. The armrest frame 12 is made of a hard resin material and forms a skeleton of the armrest 10. The arm cap 11 is made of a cushioning material in which a skin material is provided on the surface of the urethane foam, and covers the upper surface of the armrest frame 12. The armrest 10 including the armrest frame 12 and the arm cap 11 has a uniform shape in the longitudinal direction and a symmetrical shape in the width direction except for a front end portion having a chamfered shape and a rear end portion having an attachment mechanism. Yes.

  The armrest frame 12 has a substantially horizontal lower surface 12a and two side surfaces 12b and 12b provided on both sides of the lower surface 12a in the width direction. The side surfaces 12b and 12b have an inclination in which the lower side is directed inward in the width direction.

  The armrest 10 has two mounting surfaces 11a and 11a on the upper surface where the arm cap 11 is provided. The two mounting surfaces 11a and 11a have curved surfaces that descend symmetrically from the center in the width direction toward both sides in the width direction. The curved surface shapes of the mounting surfaces 11a and 11a are convex downward, in other words, convex inward in the width direction. The downwardly convex curved surface shape of the mounting surfaces 11a and 11a is smoothly continuous from the center in the width direction of the armrest 10 to the outer edge in the width direction. And in the edge of the width direction outer side, it is smoothly joined to the surface of the side surfaces 12b and 12b of the armrest frame 12 via the outer convex shape. About the downward convex shape of mounting surface 11a, 11a, specific shapes, such as a curvature, are defined so that the roundness of a seated person's arm may be assumed.

  Members such as a control unit for controlling equipment associated with the sheet 1 may be provided on the placement surfaces 11a and 11a. For example, in the case of an aircraft, an operation panel of an in-flight entertainment (IFE) system can be provided (see FIG. 5).

  The central portion in the width direction of the arm cap 11 is a top portion 11b where the upper ends of the two downwardly projecting mounting surfaces 11a and 11a are in contact. The top portion 11b is formed as an upwardly convex curved surface, and the two convex surfaces 11a, 11a on both sides are smoothly continuous with the upward convex shape of the top portion 11b.

  One such armrest 10 is attached between the adjacent seating portions 2 and 2 of the vehicle seat 1 as shown in FIG. Then, the mounting surfaces 11a and 11a lowered respectively toward the seating portions 2 and 2 on both sides are exposed to the upper surface. Each seated person seated on the seating parts 2 and 2 on both sides can place his arms (forearm parts and elbows) on the placing surface 11a facing the seating part 2 on which he / she sits.

  Since the mounting surface 11a, 11a having a curved surface that protrudes downward is provided on the upper surface of the armrest 10, the upper surface has a gentle upward convexity due to a flat surface or a cushioning material, etc., which is not inclined as usual. The area of the surface on which the seated person can place the arm can be made larger than in the case where it is formed in a shape. In particular, a large contact area can be secured between the arm and the mounting surfaces 11a and 11a by designing the downwardly convex shape of the mounting surfaces 11a and 11a so as to correspond to the roundness of the human arm. The arms can be stably supported by the mounting surfaces 11a and 11a. Thereby, a seated person can place an arm comfortably. Even when seats on both sides simultaneously place arms on the placement surfaces 11a and 11a, the space on which both arms are placed can be secured by the downwardly convex shape of the placement surfaces 11a and 11a. Moreover, since the top part 11b functions like a partition, both elbows are difficult to contact each other.

  In an aircraft or the like, the width at which the armrest 10 can be provided is limited. In this manner, the mounting surface 11a, 11a having a downwardly convex curved surface shape is provided, thereby reducing the width of the armrest 10. In addition, the occupants on both sides can place the arms comfortably. The mounting surfaces 11a and 11a are inferior to the effect of taking a larger contact area than the downwardly convex curved surface shape, but may be formed as flat surfaces descending to the side facing the seating portions 2 and 2.

  Further, in the present armrest 10, a top portion 11b is provided at the center in the width direction, and the two placement surfaces 11a and 11a descending symmetrically toward the seating portions 2 and 2 on both sides so as to be separated from the top portion 11b. The armrest 10 is visually recognized by the occupants on both sides because the armrest 10 should be shared by the occupants on both sides. That is, it becomes easy to avoid a situation in which one or both seated persons refrain from using the armrest 10 withholding the adjacent seated person or a situation in which one seated person occupies the armrest 10.

  What is necessary is just to determine arbitrarily the shape of each part of the armrest 10 including the mounting surfaces 11a and 11a according to the installation location, purpose, etc. of the armrest 10. For example, a flat surface may be provided above or below the placement surfaces 11a, 11a, that is, at the center in the width direction of the arm cap 11 or at the end edge portion. By forming the bottom convex shape of the mounting surfaces 11a and 11a so as to reach the center and the edge of the armrest 10 in the width direction, excluding the outer convex shape and the upward convex shape for joining, Wide mounting surfaces 11a and 11a can be secured. And about each mounting surface 11a, 11a on either side, even if the width | variety of the armrest 10 is made narrow by forming the height Lz of the curved surface shape up and down longer than the width Lx, the mounting surface 11a. , 11a can be easily increased. Further, as the height Lz is increased, the function as a partition of the top portion 11b is enhanced, and the elbows come into contact with each other when the adjacent seated persons place their arms on the placement surfaces 11a and 11a. In addition, the effect of visually recognizing that the armrest 10 should be shared by the seated persons on both sides is enhanced.

  Moreover, in said armrest 10, the junction part between mounting surface 11a, 11a and side surface 12b, 12b and the junction part between the two mounting surfaces 11a, 11a equivalent to the top part 11b are outside (upper side). ) Is smoothly joined with a curved surface that is convex, so that discomfort given to the seated person by contact with these joints is reduced as compared with the case where the joints are joined at an angle.

  In the armrest 10, the side surfaces 12b and 12b are provided with an inclination in which the lower side is directed inward in the width direction. By providing such an inclination, the thigh of the seated person is less likely to come into contact with the armrest 10, and comfort in the sitting posture is combined with the comfort of arm placement by the placement surfaces 11a and 11a. Can be increased. Moreover, it can contribute to weight reduction of the armrest 10.

  Since the armrest 10 has a uniform shape in the longitudinal direction, a seated person can place a wide area of the forearm portion on the placement surfaces 11a and 11a. In addition, it can be easily manufactured by extrusion molding or the like. A separately formed arm cap 11 may be attached to the upper surface of the armrest frame 12 manufactured by extrusion molding.

[Armrest according to the second embodiment]
3 and 4 show an armrest 20 according to the second embodiment of the present invention. The armrest 20 according to the second embodiment is a modification of the armrest 10 according to the first embodiment, with particular emphasis on space saving and light weight, and mainly functions as an elbow rest (elbow rest). Is. Below, it demonstrates centering around difference with 1st embodiment, and abbreviate | omits description about a common point.

  The armrest 10 according to the first embodiment has a uniform shape in the longitudinal direction except for the front end portion and the rear end portion. However, in the armrest 20 according to the second embodiment, in the longitudinal direction. Along the mounting surfaces 21a and 21a, the width of the mounting surfaces 21a and the depth of the downward convex shape change. Specifically, as shown in FIGS. 3 (b) to 3 (d) and FIGS. 4 (a) and 4 (b), on the mounting surfaces 21 a and 21 a of the arm cap 21, on the seating portions 2 and 2 of the seat 1. Elbow rests 23 and 23 are provided, which are parts where the elbow of the seated seater contacts. As shown in the top view of FIG. 3 (c) and the AA cross-sectional view of FIG. 4 (a), in the elbow placement portions 23, 23, the placement surface 21a is the most in the entire longitudinal direction of the armrest 20. , 21a is wide, and the depth of the downward convex shape is large. And as it goes to the longitudinal direction front from the elbow mounting parts 23 and 23, the width | variety of the mounting surfaces 21a and 21a becomes narrow continuously, and the depth of the downward convex shape becomes small. Further, as shown in FIGS. 3B and 3D and FIGS. 4A and 4B, at the positions of the elbow placement portions 23 and 23, a top portion 21b separating the two placement surfaces 21a and 21a is provided. It is the highest, and the height of the top portion 21b continuously decreases from the elbow placement portions 23, 23 toward the front in the longitudinal direction. Here, as “the depth of the downward convex shape”, for example, as shown in FIGS. 4A and 4B, the same width and height as the mounting surfaces 21 a and 21 a in the cross section of each part in the longitudinal direction. The distance d from the vertex of the rectangle having the actual placement surfaces 21a, 21a can be used as the representative value.

  By providing the armrest 20 with the elbow rests 23 and 23 having such a shape, as shown in FIG. 3, the seated person moves the elbow E portion of the arm A to the elbow rest 23. It can be mounted on. Since the depths of the placement surfaces 21a and 21a are the largest in the elbow placement portions 23 and 23 and decrease toward the front, the seated person places the elbows on the elbow placement portions 23 and 23. Then, the posture is such that the elbow is bent outward and the forearm is placed inside the elbow. This posture tends to bring high comfort to the seated person. A comfortable posture can be taken without placing the entire forearm portion on the armrest 20, so that the arm rests even when the armrest 20 is shorter than the average forearm length of the seated person. It is difficult to reduce the comfort related to installation. Therefore, the total length of the armrest 20 can be made shorter than when it is assumed that almost the entire forearm is placed as in the first embodiment. Furthermore, in this armrest 20, the contact between the elbows of the seated occupants seated next to each other can be effectively suppressed by raising the top portion 21b at the position of the elbow placement portions 23, 23.

  Thus, in this armrest 20, if the width of the mounting surfaces 21a and 21a and the height of the top portion 21b in the elbow mounting portions 23 and 23 are sufficiently large, the comfort for the seated person is ensured. However, it is possible to reduce the width of the mounting surfaces 21a and 21a and the height of the top portion 21b in front of it. Moreover, the length of the armrest 20 whole can be shortened. Therefore, it is possible to reduce the space occupied by the armrest 20 as compared with the case of having a substantially uniform shape in the longitudinal direction as in the first embodiment. Moreover, since the volume of the material which comprises the armrest 20 becomes small, the armrest 20 can be reduced in weight. Particularly in an aircraft, it is important to reduce the weight of each member to be mounted.

[Armrest according to the third embodiment]
FIG. 5 shows an armrest 30 according to the third embodiment of the present invention. The armrest 30 according to the third embodiment is also a modified form of the armrest 10 according to the first embodiment, and can be used in two ways by deployment. Below, it demonstrates centering around difference with 1st embodiment, and abbreviate | omits description about a common point.

  In the armrests 10 and 20 according to the first and second embodiments, the left and right portions sandwiching the top portions 11b and 21b at the center in the width direction are made of continuous members, but the armrest according to the third embodiment. 30 has two members divided at the center in the width direction.

  Specifically, the armrest 30 includes a support portion 31 and two rotating portions 32 and 32. The support portion 31 is coupled to the frame of the seating portion 2 so as to be rotatable in the front-rear direction. And the rotation parts 32 and 32 are supported by the support part 31 so that it can respectively rotate independently around the rotating shafts 31a and 31a along the front-back direction (longitudinal direction). The rotating units 32 and 32 are moved 90 to the outer side in the width direction from the storage state (first rotation state) shown in FIGS. 5A and 5B and the storage state shown in FIGS. Rotation is possible between the separated deployment states (second rotation states). In the two rotating parts 32, 32, the rotation is locked in the retracted state and the unfolded state by a lock mechanism (not shown).

  The shape of the rotation parts 32 and 32 is demonstrated on the basis of the storage state shown to Fig.5 (a), (b). Each rotating portion 32 has three surfaces along the front-rear direction of the first surface 32a, the second surface 32b, and the third surface 32c. The second surface 32b and the third surface 32c have a planar shape parallel to each other, and extend upward from the rotation shaft 31a. The second surface 32b is located at the center in the width direction of the armrest 30. When the two rotating portions 32 and 32 are both in the retracted state, the second surfaces 32b and 32b are positioned at the center in the width direction of the armrest 30. It will be in the state which mutually opposed on both sides. The third surface 32c is located on the outer side in the width direction of the armrest 30 with the first surface 32a interposed therebetween. The second surface 32b is formed higher than the third surface 32c. The distance L1 between the second surface 32b and the third surface 32c along the width direction is shorter than the height L2 of the second surface 32b.

  The first surface 32 a is a surface provided between the upper end portion of the second surface 32 b and the upper end portion of the third surface 32 c, and has a curved surface shape that is convex toward the inside of the rotating portion 32. Since the upper end of the second surface 32b is higher than that of the third surface 32c, the first surface 32a is a downwardly convex curved surface that descends outward. A control unit 33 such as an operation panel of the IFE system is provided on the first surface 32a.

  Thus, when the rotation part 32 is in the retracted state, the first surface 32a exposes a curved surface shape that protrudes downward on the upper surface. That is, the first surface 32a functions as a mounting surface having the same configuration as the mounting surface 11a in the armrest 10 according to the first embodiment.

On the other hand, when the rotating portion 32 is rotated 90 ° outward from the retracted state to the expanded state shown in FIGS. 5C and 5D, the second surface 32b faces upward and is substantially horizontal with no inclination. To expose a flat surface. The first surface 32a faces sideways with the lower side having an inclination toward the center in the width direction.

  Thus, in the retracted state, the first surface 32a is exposed upward to form a mounting surface having a curved slope, and can be used by a seated person to mount the arm. On the other hand, in the unfolded state, the second surface 32b exposes a flat surface without an inclination upward. The seated person can also use this flat second surface 32b to mount the arm. The second surface 32b can also be used as a small table. Thus, by selecting the rotation state of the rotation unit 32, one of the first surface 32a and the second surface 32b can be selected and exposed upward to be used for arm placement or the like. . In addition, since the two rotating parts 32 and 32 rotate independently, the seated persons on both sides are independent of the state of the rotating part 32 on the other seated person's side, and the rotating part 32 on its own side. Can be freely selected.

  As described above, in each rotation part 32, the distance L1 between the second surface 32b and the third surface 32c is shorter than the height L2 in the retracted state of the second surface 32b. The width occupied by 32 is smaller in the retracted state than in the unfolded state. That is, if the rotating part 32 is set in the retracted state, the movement of the seated person is less likely to be hindered by the armrest 30 when sitting or leaving the seat. On the other hand, in the unfolded state, although the space occupied by the armrest 30 becomes large, it is possible to place an arm or the like on the wide second surface 32b with a relatively large margin. In the unfolded state, the first surface 32a serving as a side surface has an inclination, so that the armrest 30 does not easily come into contact with the thigh of the seated person on the side even if the width of the second surface 32b is wide. ing.

  In order to place the entire forearm portion on the armrest 30, from the viewpoint that the second surface 32b in the deployed state should be used instead of the first surface 32a in the stored state, the first surface 32a in the stored state is Thus, it is not necessary to have such a width that the entire forearm portion can be placed. For example, the first surface 32a in the retracted state only needs to have a width that can be used as an elbow rest (elbow rest) on which only the elbow part is placed. Then, the width | variety of the armrest 30 in a retracted state can be designed narrowly rather than the case where the armrest 10 which does not take a deployment state can be utilized for mounting of a forearm part like 1st embodiment. Therefore, the space saving of the armrest 30 can be further reduced than in the first embodiment. In some cases, such as when the seated person is large, the unfolded state may not be used depending on the situation of the seating unit 2, but even in such a case, the first surface 32a in the retracted state should be a minimum elbow rest. Easy to use.

[Other Embodiments]
In the above-described three embodiments, the armrests 10, 20, and 30 are assumed to be provided between a plurality of adjacent seating portions 2, and from the center in the width direction to both sides so that seaters on both sides can easily share. It had a mounting surface. However, in the armrests provided on the outside of the seating parts at both ends of the plurality of seating parts provided adjacent to each other or on the side of the seating parts independent of other seating parts, only one user uses the armrest. Therefore, there is no need to provide a mounting surface inclined in two directions.

  In such a case, it suffices to provide only one flat or downwardly convex mounting surface that is lowered toward the side facing the seating portion on the upper surface of the armrest. In that case, the mounting surface may be formed over the entire width direction of the armrest or may be formed in a partial region.

  As mentioned above, although embodiment of this invention was described in detail, this invention is not limited to the said embodiment, A various change is possible in the range which does not deviate from the summary of this invention.
