Description

  The present invention relates to an armrest, and more specifically, a first member in which a pivot member provided on one end side of a base member constituting a vehicle interior member is pivotally provided, and the other end side is close to the base member. The present invention relates to an armrest that is displaceable to a posture and a second posture separated from the base member.

  In various automobiles such as passenger cars, in the case of a vehicle in which the left and right front seats (driver's seat and front passenger seat) are installed at appropriate intervals, for example, as illustrated in FIG. 17, on the floor adjacent to the front seat S, There are many forms in which a floor console FC, which is a vehicle interior member, is installed. The floor console FC mainly includes a console body 10 having a shift lever SL, a parking brake lever PL, and the like provided on the front upper surface and an article storage portion 12 provided in the rear side. A console lid 16 that pivotably closes the upper opening 14 of the article storage unit 12 is pivotally provided at the upper part. Further, since the console lid 16 is located on the side of the front seat S, the upper surface of the console lid 16 also has a function as an armrest AR.

Here, when the occupant seated on the front seat S adjusts the above-described armrest AR to a height position where it can be used appropriately, for example, when the parking brake lever PL is gripped and pulled up to operate the parking brake, The elbow) may come into contact with the front end portion of the armrest AR, and proper lever operation may be impaired. Further, because the height position of the armrest AR that is optimal for each occupant varies depending on the physique difference of the occupant seated on the front seat S, a tilt-up function is required. Therefore, conventionally, as illustrated in FIG. 17, the console lid 16 and the armrest AR are separated from each other, the console lid 16 is used as a base member, and the rear end side of the armrest AR is rotatably attached by the pivot 18. A type, a type that moves up and down in a substantially horizontal posture although not shown, and the like have been proposed. The armrest AR illustrated in FIG. 17 is in a first posture (indicated by a two-dot chain line in the figure) in which the front end side is brought close to the console lid 16 when the parking brake lever PL is operated or in a low posture, and in a high posture. A second posture (shown by a solid line in the figure) is lifted by separating the front end side from the console lid 16. In addition, the technique regarding the armrest which can change attitude | position is disclosed by the cited reference 1, etc., for example.

  By the way, in the conventional tilt-up type armrest AR which is the above-described rotation type, the pivotal support portion 18 for realizing the rotational displacement is located on the rear end side of the armrest AR as described above. The so-called “cantilever type” was mostly used. That is, since it is supported by the console lid 16 only at the rear portion, when it is pulled up to the second posture, the front end side is lifted and is not supported at all by the console lid 16. In other words, the conventional support structure for the armrest supports the load generated when the own weight and the occupant put the arm (elbow) on only the above-described pivot portion 18, and thus the pivot portion 18 has a large number of rigidity. Therefore, it is necessary to form a strong structure from a strong part (metal part or the like) having the above-mentioned problem, and there is a problem that causes an increase in weight and cost due to a part related to the pivot part 18.

  Since the armrest AR is installed at a position adjacent to the front seat S or on the upper surface of the rear seat, for example, an occupant moving on the seat or in the passenger compartment may hold his / her posture by holding his / her hand or arm. When collapsed, a considerable load may be applied. In this way, when considering an excessive load significantly exceeding the normal use state, it is necessary to design and manufacture the above-described pivotal support portion 18 more firmly. It was even bigger. Note that the console lid disclosed in Patent Document 1 described above also has a similar problem because it has a structure that supports a load by a link shaft.

A reciprocating guide portion 101 extending substantially perpendicularly to the upper surface of the lid body 20 from the lowest point P1 to the branch point P5, a first guide portion 102 extending from the branch point P5 to the uppermost point P2, A second guide part 104 extending from the uppermost point P2 to the intermediate point P3, a third guide part 106 extending obliquely from the intermediate point P3 to the passing point P4, and extending from the passing point P4 to the aforementioned branch point P5 The fourth guide unit 108 is divided. Among these, the 1st guide part 102 and the 2nd guide part 104 comprise the bent outward guide groove used as the movement path of the guide pin 78, when displacing the armrest AR from a 1st attitude | position to a 2nd attitude | position, The third guide part 106 and the fourth guide part 108 constitute a bent return path guide groove that becomes a movement path of the guide pin 78 when the armrest AR is displaced from the second position to the first position.

  Here, the above-mentioned “bent shape” defined by the present application means that the extending direction of the outward guide groove and the backward guide groove such as “inverted V shape” or “heavy shape” exemplified in the present embodiment is abrupt. It includes a refraction form that changes, a curved form in which the extending directions of the forward guide groove and the backward guide groove gradually change, such as “inverted U-shape” or “upward convex arc shape”.

  The reciprocating guide portion 101 is set to have the same width as the boss guide groove 98 from the lowest point P1 to the middle, and is set so that the width gradually decreases from the middle toward the branch point P5. The first guide portion 102 extends from the branch point P5 to the uppermost point P2 in a state of being gently bent at a substantially middle portion, and is set to have a width such that the guide pin 78 is in sliding contact. The second guide portion 104 extends from the uppermost point P2 to the intermediate point P3 while being gently bent at a substantially intermediate portion so as to be symmetric with the first guide portion 102, and the guide pin 78 is in sliding contact with the first guide portion 102. The width is set. Accordingly, the forward guide groove formed of the first guide portion 102 and the second guide portion 104 extends so as to be refracted at an angle slightly smaller than a right angle at the uppermost point P2.

  Further, the third guide portion 106 linearly extends obliquely upward from the intermediate point P3 toward the passing point P4 located directly below the uppermost point P2, and is set to have a width that allows the guide pin 78 to slide. ing. Further, the fourth guide portion 108 linearly extends obliquely downward from the passing point P4 toward the branch point P5, and is set to have a width such that the guide pin 78 is in sliding contact. Therefore, the return path guide groove including the third guide portion 106 and the fourth guide portion 108 extends so as to be refracted at an angle slightly larger than a right angle at the passing point P4. The depth of the fourth guide unit 108 is set to be appropriately smaller than the depths of the reciprocating guide unit 101 and the first guide unit 102. When the armrest AR arrives at the first posture, the guide pin 78 arrives at the lowest point P1, and when the armrest AR arrives at the second posture, the guide pin 78 arrives at the intermediate point P3. Is set.

  Further, at the boundary portion between the first guide portion 102 and the second guide portion 104, the boundary portion between the second guide portion 104 and the third guide portion 106, and the boundary portion between the third guide portion 106 and the fourth guide portion 108 Are formed with first to third protrusions 110, 112, 114 having an inclined surface 116 and a vertical surface 118, respectively. As shown schematically in FIG. 8, in the first protrusion 110, when the guide pin 78 moves from the first guide portion 102 to the second guide portion 104, the guide pin 78 that contacts the inclined surface 116 moves backward. The movement of the guide pin 78 from the second guide unit 104 to the first guide unit 102 is restricted by the vertical surface 118. Further, as schematically illustrated in FIG. 8, the second protrusion 112 allows the guide pin 78 to move from the second guide portion 104 to the third guide portion 106 by the inclined surface 116, and from the third guide portion 106 to the second guide portion 106. 2 The movement of the guide pin 78 to the guide unit 104 is restricted by the vertical surface 118. Similarly, as schematically shown in FIG. 8, the third protrusion 114 allows the movement of the guide pin 78 from the third guide portion 106 to the fourth guide portion 108 by the inclined surface 116, and from the fourth guide portion 108. The movement of the guide pin 78 to the third guide portion 106 is restricted by the vertical surface 118. Therefore, when the armrest AR is displaced from the first posture to the second posture, the guide pin 78 moves from the reciprocating guide portion 101 → the first guide portion 102 → the second guide portion 104, and the armrest AR is moved from the second posture to the second posture. When displacing to one posture, the third guide unit 106 → the fourth guide unit 108 → the reciprocating guide unit 101 is moved.

  That is, since the armrest AR of the present embodiment includes the support mechanism 60 having the above-described configuration, when the armrest AR is displaced from the first posture to the second posture, the armrest AR is temporarily lifted upward from the second posture and then the second posture. By returning to the posture, the second posture is suitably stopped and supported. Specifically, when the armrest AR stopped in the first posture is tilted up by pulling up the front end side while grasping the finger hook portion 48, the guide pin 78 is moved in the process of the upward movement of the support member 62. However, as illustrated in FIG. 9 and FIG. 10, after the reciprocating guide 101 is moved upward from the lowest point P1, the first guide 102 in the forward guide groove is moved through the branch point P5, and the first guide After passing through the protrusion 110, it arrives at the uppermost point P2. At this time, since the guide boss 76 abuts against the wall surface of the boss guide groove 98, the armrest AR is restricted from further upward rotation.

  When the lifting operation on the armrest AR is released here, the biasing force of the first torsion spring 46 acts on the armrest AR, so that the movement toward the first guide portion 102 is restricted by the first protrusion 110. The guide pin 78 moves from the uppermost point P2 in the second guide portion 104 in the outward guide groove, and after passing through the second protrusion 112, arrives at the intermediate point P3. Accordingly, the support member 62 is gradually rotated backward while moving upward as the guide pin 78 moves in the forward guide groove (the first guide portion 102 and the second guide portion 104) of the pin guide groove 100. Since the posture is displaced, the first contact surface portion 64 contacts the first contact receiving surface portion 68 of the lid body 20 and the second contact surface portion 66 contacts the second contact receiving surface portion 70 of the armrest body 32. The state is sandwiched between the armrest AR and the console lid 16. As a result, the armrest AR is stopped and stably held by the console lid 16 via the support member 62 under the biasing force of the first torsion spring 46.

  On the other hand, when the armrest AR is displaced from the second posture to the first posture, the armrest AR is preferably returned to the first posture if the armrest AR is once lifted up and appropriately returned from the second posture. Specifically, when the armrest AR stopped in the second posture is slightly tilted up by pulling up the front end side while grasping the finger hook portion 48, the guide pin is moved in the process in which the support member 62 is moved up and down. 78, as illustrated in FIGS. 11 and 12, since the second protrusion 112 restricts the movement of the second guide portion 104 toward the second guide portion 104, the third guide portion 106 in the return guide groove from the intermediate point P3 is changed. After moving and passing through the third protrusion 114, it arrives at the passing point P4. At this time, since the guide pin 78 abuts against the wall surface of the pin guide groove 100, the armrest AR is restricted from further upward rotation.

  When the lifting operation on the armrest AR is released here, the urging force of the first torsion spring 46 acts on the armrest AR, so that the guide pin 78 moves from the passing point P4 to the fourth guide portion 108 in the return path guide groove. Then, the fourth guide unit 108 moves to the branch point P5 and returns to the reciprocating guide unit 101, and the reciprocating guide unit 101 moves downward to arrive at the lowest point P1. Accordingly, the support member 62 moves forward while moving downward by moving the reciprocating guide portion 101 after the guide pin 78 moves in the backward guide groove (the third guide portion 106 and the fourth guide portion 108) of the pin guide groove 100. Since the posture is displaced so as to rotate gradually, the contact between the first contact surface portion 64 and the first contact receiving surface portion 68 and the contact between the second contact surface portion 66 and the second contact receiving surface portion 70 are released. Is done. As a result, the armrest AR returns to the first posture under the urging force of the first torsion spring 46 and is stably held in this first posture.

  Further, the armrest AR of the present embodiment is configured so that when the console lid 16 approaches the console body 10 (floor console FC) (closed state), the armrest AR is displaced from the first posture to the second posture and the second Displacement from the posture to the first posture is allowed, and when the console lid 16 is separated from the console body 10 (floor console FC) (open state), the armrest AR is displaced from the first posture to the second posture and A lock mechanism 120 that restricts displacement from the two postures to the first posture is provided. As shown in FIGS. 1, 3 and 6, the locking mechanism 120 is provided at the front side portion of the console lid 16 so as to be capable of displacement in posture, and is a projecting pin that can contact the console body 10 of the floor console FC. The lock member 122 has a locking portion 126 facing the contact portion 124 and the armrest AR. The above-described upper wall portion 82 of the support member 62 attached to the back side member 34 of the armrest AR functions as a first locking portion that locks the locking portion 126 so that the locking portion 126 is detachable when the armrest AR is in the first posture. In addition, the above-described lower wall portion 83 of the support member 62 functions as a second locking portion for locking the locking portion 126 so that the locking portion 126 is detachable when the armrest AR is in the second posture.

  The lock member 122 is an L-shaped member that is pivotally supported on the lid body 20 by using a pivot shaft 122A, and is on the distal end side of a substantially horizontal portion that extends toward the front of the console lid 16. Is further divided into two branches. Further, the above-described projecting pins 124 and 124 facing the openings 22A and 22A provided in the cover member 22 project downward from the lower surface of the respective tip portions divided into two. An upper wall portion (first locking portion) 82 and a lower wall portion (second locking portion) provided on the support member 62 are provided at the front end side of a substantially vertical portion extending upward of the console lid 16. The above-described locking portion 126 that is detachably locked to the 83 is provided. As illustrated in FIG. 1 and the like, the lock member 122 is elastically urged counterclockwise in FIG. 1 by the second torsion spring 128 disposed between the protrusion 20D and the opening 22A. , 22A projecting downwardly and projecting pins 124, 124 are projected downward, and the latching portion 126 is elastically biased toward the first state where the latching portion 126 is latched to the upper wall portion 82 or the lower wall portion 83 provided on the support member 62. Has been.

  According to such a locking mechanism 120, in the closed state (FIGS. 1 and 3) in which the console lid 16 is brought close to the console body 10 (floor console FC), the projecting pins 124 facing the openings 22A and 22A, Since 124 abuts on the upper surface of the console main body 10, the lock member 122 is rotated and displaced rearward against the urging force of the second torsion spring 128 and displaced to the second state. As a result, the locking state between the upper wall portion 82 or the lower wall portion 83 provided on the support member 62 and the locking portion 126 is released, so that the armrest AR is displaced from the first posture to the second posture, or second. Displacement from the posture to the first posture is allowed.

  On the other hand, in the opened state in which the console lid 16 is separated from the console body 10 (floor console FC), as illustrated in FIGS. 13 and 14, the contact of the console body 10 with the projecting pin 124 is released. The lock member 122 is rotationally displaced forward by the urging force of the second torsion spring 128 and displaced to the first state. As a result, the upper wall portion 82 or the lower wall portion 83 provided on the support member 62 and the locking portion 126 are locked, so that the armrest AR is displaced from the first posture to the second posture or the second posture. The displacement from the first posture to the first posture is restricted.

  That is, when the console lid 16 is opened in a state where the armrest AR is stopped in the first posture, the engaging portion 126 of the lock member 122 displaced in the first state is supported by the support member 62 as illustrated in FIG. Since the support member 62 is restricted from being displaced, the displacement of the armrest AR to the second posture is restricted. Further, when the console lid 16 is opened in a state where the armrest AR is stopped in the second posture, as illustrated in FIG. 14, the engaging portion 126 of the lock member 122 displaced to the second state is the support member 62. Since the support member 62 displaced upward is restricted, the displacement of the armrest AR to the first posture is restricted.

  The armrest AR of the present embodiment configured as described above has a support member 62 and a lid that are formed in a block shape and have high rigidity when the armrest AR tilted upward from the console lid 16 reaches the second posture. The main body 20 comes into contact with the support member 62 and the armrest main body 32 comes into contact with the main body 20. That is, since the armrest AR is supported by the console lid 16 via the support member 62, for example, when an excessive load is applied from above to the elbow receiving portion on the upper surface, the armrest AR is supported by the support member 62 and the console lid 16. As a result, excessive stress is not applied only to the pivot 38. Accordingly, since the armrest AR is appropriately supported by a simple configuration in which the pivotal support portion 38 and the support member 62 having a simple structure are provided, the armrest AR can suitably cope with an excessive load while reducing the weight and cost. Can do. In particular, since the support member 62 is disposed below the portion of the armrest AR where the load is most likely to be applied, the structure can support the load appropriately. Further, since the first contact surface portion 64 and the second contact surface portion 66 are formed as substantially parallel surfaces, when a load is applied to the armrest AR, the back surface member 34 and the support member 62 Slip is unlikely to occur between the support member 62 and the lid body 20, and the load can be efficiently supported.

  The support member 62 is attached to the armrest body 32 of the armrest AR so as to be rotatable, and is attached to the lid body 20 of the console lid 16 so as to be slidable. The armrest AR displaced to the second posture can be preferably supported at the same time. In addition, the support member 62 is displaced by an amount necessary for avoiding interference between the first contact surface portion 64 and the first contact receiving surface portion 68 when the armrest AR is displaced between the first posture and the second posture. The posture is always controlled to stand up toward the console lid 16. As a result, the storage area for the support member 62 provided on the console lid 16 (lid body 20) can particularly minimize the size in the front-rear direction, leading to an increase in the size of the console lid 16 and the armrest AR. There is nothing. Further, the posture displacement defect of the support member 62 is less likely to occur.

  Further, in the armrest AR of the present embodiment, the armrest AR is provided on the support member 62 attached to the back member 34 when the armrest AR is displaced from the first posture to the second posture and when the armrest AR is displaced from the second posture to the first posture. Since the guide pin 78 slides along the pin guide groove 100 of the guide member 96 provided on the lid body 20 of the console lid 16, the posture of the support member 62 is appropriately controlled in accordance with the posture displacement of the armrest AR. The In addition, the pin guide groove 100 includes an outward guide groove formed by the first guide portion 102 and the second guide portion 104 that serve as a movement path of the guide pin 78 when the armrest AR is displaced from the first posture to the second posture, When the AR is displaced from the second position to the first position, the AR is divided into a return guide groove formed by a third guide part 106 and a fourth guide part 108 that serve as a movement path of the guide pin 78. For this reason, after the guide pin 78 moves from the first guide portion 102 to the second guide portion 104 and reaches the uppermost point P2 in the middle of displacing the armrest AR from the first posture to the second posture, It is possible to prevent the inconvenience of going back. Similarly, in the middle of displacing the armrest AR from the second posture to the first posture, the guide pin 78 moves from the third guide portion 106 to the fourth guide portion 108 and reaches the passing point P4. It is possible to prevent the inconvenience of going back.

  Furthermore, in the armrest AR of the present embodiment, by providing the lock mechanism 120, the armrest AR is changed from the first posture to the second posture in the opened state in which the console lid 16 is separated from the console body 10 (floor console FC). Or the displacement from the second posture to the first posture can be regulated. This suitably prevents the armrest AR from being inadvertently displaced with respect to the console lid 16 in a state where the console lid 16 is opened when an article is taken in and out of the article storage portion 12 of the console body 10. obtain. Only when the console lid 16 attached to the console main body 10 of the floor console FC is closed and stably held on the console main body 10 is the displacement of the armrest AR from the first posture to the second posture and Since the displacement from the second posture to the first posture is allowed, the safety when using the armrest is improved. In particular, since the support member 62 is fixed regardless of whether the armrest AR is in the first posture or the second posture, the armrest AR is appropriately fixed in both the first posture and the second posture. Furthermore, in the open state where the console lid 16 is separated from the console body 10 of the floor console FC, the lock member 122 is held in the first state by the second torsion spring 128, so that the armrest AR with respect to the console lid 16 is held. Fixed holding is ensured.

  The support member 62 may be attached to the lid main body 20 of the console lid 16 so as to be rotatable and to be slidably attached to the rear side member 34 of the armrest AR, contrary to the above-described embodiment. In the case of such an attachment configuration, the support member 62 can be displaced in a posture in which the support member 62 is always erected from the console lid 16 toward the armrest AR. The guide member 96 is attached to the lower surface of the armrest main body 32 of the armrest AR so as to extend downward. With respect to the pin guide groove 100 formed in the guide member 96, the first guide portion 102 and the second guide portion 104 are provided. The bent outward guide groove formed of a V shape, an inverted heft shape, a U shape, or a downwardly convex arc shape, and a bent return guide groove formed of the third guide portion 106 and the fourth guide portion 108 , V-shaped, inverted heft-shaped, U-shaped, or downward convex arc shape. Even if the mounting manner of the support member 62 is such, the posture of the armrest AR with respect to the console lid 16 can be suitably allowed, and at the same time, the armrest AR displaced to the second posture can be suitably supported. Further, when the armrest AR is displaced between the first posture and the second posture, the support member 62 is displaced by an amount necessary for avoiding interference between the first contact surface portion 64 and the first contact receiving surface portion 68. Therefore, the storage area for the support member 62 provided in the armrest AR (back side member 34) can minimize the size in the front-rear direction, and thus the armrest AR and the console lid 16 are increased in size. There is nothing to do.

  In the above-described embodiment, the first locking portion and the second locking portion that are locked by the locking portion 126 of the lock member 122 are the upper wall portion 82 and the lower wall portion 83 of the support member 62. You may make it provide a 1st latching | locking part and a 2nd latching | locking part in either the armrest main body 32 or the back side member 34 which comprises the armrest AR. Even in such a configuration, the armrest AR can be securely fixed to the console lid 16 in the opened state in which the console lid 16 is separated from the console body 10.

  Further, in the above-described embodiment, the console lid 16 that opens and closes the article storage unit 12 by being attached to the floor console FC provided with the article storage unit 12 so as to be able to approach and separate is exemplified as the base member. Although explained as a case of functioning as a lid of the article storage unit 12, the base member is not limited to this. For example, as illustrated in FIG. 16, the base member may be a seat constituent member 130 attached to an automobile seat (rear seat) S or the like, and an armrest AR attached to the seat constituent member 130 so as to be rotatable. In contrast, the above-described support structure can be suitably implemented. The seat constituent member 130 to which the armrest AR is attached is displaced in this way, so that the armrest AR is positioned on the seat S when the armrest AR is used, and is retracted from the seat S when the armrest AR is not used. The armrest AR itself can be stored in the seat S.

  An armrest according to the present invention is disposed so as to be rotatable by a pivotal support provided on one end side with respect to a base member constituting a vehicle interior member, and a first posture in which the other end side is close to the base member and the base member The armrest is displaceable in a second posture separated from the armrest, and can be implemented in an armrest equipped in various vehicles such as an automobile.
