  By the way, in the case of an occupant with a small physique such as a woman or a child, inconvenience such as difficulty in reaching the armrest while sitting on the vehicle seat may occur. An armrest that can be moved indoors is also desired. On the other hand, measures such as attaching a separate armrest cover to the existing armrest and changing the width in the vehicle interior / exterior direction have been taken, but there is room for improvement in terms of design and economy. In consideration of the location of the armrest, the impact at the time of a vehicle-side collision, etc., a very complicated mechanism is not preferable from the viewpoint of occupant protection.

  This invention is completed based on the said situation, Comprising: It aims at providing the armrest for vehicles which can implement | achieve the smooth movement of an elbow rest surface by a comparatively simple method.

  In order to solve the above-described problems, a vehicle armrest according to the present invention includes an armrest upper surface portion constituting an occupant's elbow rest surface, and an armrest side surface extending downward from the armrest upper surface portion and constituting a vehicle interior side surface of the armrest A first armrest member, a first facing portion that faces the armrest upper surface portion, and a second facing portion that faces the armrest side surface portion, and is separate from the first armrest member. A vehicle armrest that includes a second armrest member that supports the first armrest member from below, and the first armrest member is movable relative to the second armrest member in a vehicle width direction. The first armrest member is engaged with the second armrest member on the back surface of the upper surface of the armrest. A plurality of guide pins extending in a direction following the relative movement direction of the first armrest member toward the second armrest member on the back surface of the side surface portion of the armrest. The portion is provided with a locked portion that locks the locking portion in a state in which the movement of the first armrest member in the vehicle width direction is allowed while the movement in the vertical direction is suppressed. Guide holes through which the guide pins are inserted are respectively provided in the facing portions, and an inflatable and deflated air bag is disposed between the armrest side surface portion and the second facing portion. And

  According to such a vehicle armrest, the guide pin provided in the direction following the relative movement direction (vehicle width direction) of the first armrest member on the back surface of the armrest side surface portion, and the first armrest member relative to the back surface of the armrest upper surface portion. The relative movement direction of the first armrest member can be more reliably guided by the locking portion provided in a movable state. Further, since the locking portion is configured to be locked in a state in which the movement of the first armrest member in the vertical direction is suppressed, the first armrest member can be moved relative to the second armrest member in the vehicle width direction. However, it is possible to restrict the movement in the vertical direction. As described above, in the configuration in which the first armrest member is relatively moved by the expansion / contraction function of the air bag disposed between the first armrest member and the second armrest member, the guide pin and the locking portion may The first armrest that regulates unwanted vertical movement while guiding the movement in the vehicle width direction of the first armrest member with the elbow rest surface without being affected by the bulging or shrinking bias Smooth movement of the member can be realized.

  In the vehicle armrest, an elastic member that is elastically deformed in a relative movement direction of the first armrest member may be interposed between the first armrest member and the second armrest member. According to such a vehicle armrest, it is possible to promote the contraction of the air bladder by the elastic member, and the movement of the first armrest member toward the outside of the passenger compartment becomes smooth.

  The vehicle armrest may be provided in a door trim, and the door trim may be provided with an insertion hole through which an outer end portion of the first armrest member that moves relative to the upper end of the armrest is inserted. . According to such a vehicle armrest, the first armrest member is configured to relatively move in the vehicle width direction, but in the inflated and contracted state of the air bag, between the outer end of the armrest and the door trim at the upper surface of the armrest. Since no gap is generated, the design of the entire door trim can be maintained.

  ADVANTAGE OF THE INVENTION According to this invention, the armrest for vehicles which can implement | achieve the smooth movement of an elbow rest surface by a comparatively simple method can be provided.

In front of the armrest 50, a pull handle 6 having an upper opening and a switch 7 for operating a window are provided so that a passenger can insert a hand when opening and closing the vehicle door from the vehicle interior side. . As shown in FIGS. 2 to 4, the armrest 50 is separated from the first armrest member 10 and the first armrest member 10. The second armrest member 20 supports the first armrest member 10 from below. It is comprised including. The first armrest member 10 is attached to the second armrest member 20 so as to cover the second armrest member 20 from the upper side of the vehicle and the vehicle interior side and to be movable relative to the second armrest member 20 in the vehicle width direction (FIGS. 3 and 4). reference).

  The first armrest member 10 includes a first armrest member side upper surface portion 11 (corresponding to an “armrest upper surface portion”) that extends substantially horizontally and constitutes an occupant's elbow rest surface, and a vehicle on the first armrest member side upper surface portion 11. The first armrest member side vehicle interior side surface portion 12 (corresponding to the “armrest side surface portion”) that extends downward from the indoor side end portion 11T and constitutes the vehicle interior side surface is substantially L-shaped in cross section. (See FIGS. 3 and 4). As shown in FIG. 3, the first armrest member 10 includes a base material 15 that serves as a base, a cushion material 16, and a skin material 17. The skin material 17 is configured by integrally including a urethane slab foam layer 18 on the back surface 17B. A plurality of locking portions 40 (40 </ b> A, 40 </ b> B, 40 </ b> C) that lock the first armrest member 10 with respect to the second armrest member 20 are provided on the back surface 11 </ b> B of the upper surface portion 11 on the first armrest member side. . Each of the locking portions 40 is a member that can slide in the vehicle width direction within a slide rail 44 provided in the second armrest member 20, and is provided with three pieces spaced apart from each other in the vehicle front-rear direction (FIG. 2). reference).

  Further, the rear surface 12B (the vehicle exterior side surface) of the side surface portion 12 of the first armrest member side vehicle interior follows the relative movement direction (vehicle width direction) of the first armrest member 10 toward the second armrest member 20. A plurality of guide pins 30 extending to the outdoor side are provided. These guide pins 30 are respectively inserted into guide holes 30 </ b> H provided in the second armrest member 20 described later, and the first armrest member 10 is attached to the second armrest member 20. The guide pin 30 includes a front guide pin 30F provided near the vehicle front and a rear guide pin 30R provided near the vehicle rear. The front guide pin 30F is a pair of a guide pin 31 disposed below and a guide pin 32 disposed above the guide pin 31, and the rear guide pin 30R is also relatively below. A guide pin 33 disposed on the guide pin 33 and a guide pin 34 disposed above the guide pin 33 form a pair.

  The second armrest member 20 is a substantially box-shaped board member that is integrally provided in an armrest recess 55 formed at the boundary between the middle board 2 and the lower board 3 (see FIG. 2). The second armrest member 20 includes a second armrest member-side upper surface portion 21 (corresponding to a “first opposing portion”) that extends substantially horizontally and faces the first armrest member-side upper surface portion 11, and the second armrest member-side upper surface. The second armrest member-side vehicle interior side surface portion 22 ("the second opposing portion") extends downward from the vehicle interior-side end portion 21T of the portion 21 and faces the vehicle interior side and faces the first armrest member-side vehicle interior side surface portion 12. For example).

  A slide rail 44 (44A, 44B, 44C) for locking a locking portion 40 (40A, 40B, 40C) provided on the first armrest member 10 ("locked") is provided on the upper surface portion 21 on the second armrest member side. Corresponding to “parts”) are provided at corresponding positions. Each slide rail 44 is provided so as to extend in the vehicle width direction, and the vehicle intersects with the relative movement direction while allowing each locking portion 40 to move in the relative movement direction (vehicle width direction) of the first armrest member 10. It is set as the structure which latches in the state which suppressed the movement to an up-down direction, respectively. That is, the first armrest member 10 is attached to the second armrest member 20 so as to be movable relative to the second armrest member 20 by the above-described guide pins 30 and the locking portions 40.

  Further, the guide hole 30H (31H, 32H, 33H, 34H) through which the guide pin 30 (31, 32, 33, 34) provided in the first armrest member 10 is inserted in the second armrest member side vehicle interior side surface portion 22 is provided. ) Are formed in the corresponding positions in the vehicle width direction. Each guide pin 30 (31, 32, 33, 34) is provided with a spring 60 (corresponding to an “elastic member”) in a state where the guide pin 30 is inserted into the corresponding guide hole 30H. The one end 62 is connected to the tip 39 in the standing direction of each guide pin 30 (see FIG. 3).

  The length of each spring 60 is designed so that the spring 60 is in a steady state in the accommodated state of the first armrest member 10 shown in FIG. In other words, the length of each spring 60 in the steady state is the portion of each guide pin 30 that is exposed to the vehicle compartment outside from the back surface 22B of the second armrest member side vehicle interior side surface portion 22 in the accommodated state of the first armrest member 10. Designed to roughly correspond to the length of It can be said that a spring 60 that elastically deforms in the relative movement direction of the first armrest member 10 is interposed between the first armrest member 10 and the second armrest member 20. The position where the spring 60 is provided is not limited to this, and can be changed as appropriate.

  An air bag 70 that can be inflated and contracted between the first armrest member 10 (first armrest member side vehicle interior side surface portion 12) and the second armrest member 20 (second armrest member side vehicle interior side surface portion 22). (See FIGS. 2 to 4). The air bag 70 has a longitudinal shape that follows the shape of the armrest 50 and a substantially rectangular shape in plan view, and is formed of a relatively hard resin with flexibility that allows expansion and contraction. An air inflow port 77 connected from the bag main body portion 75 into which air flows is formed at a position which is substantially the center in the longitudinal direction of the air bag 70 and which is located below the armrest 50 (see FIG. 2). On the other hand, an air inflow opening 57 is formed in the bottom wall 59 of the armrest recess 55, and an air inflow port 77 of the air bag 70 can be inserted. The tip of the air inflow port 77 inserted into the air inflow opening 57 is connected to an actuator (not shown) so that air can flow into the bag main body 75.

  Further, an insertion hole 51 through which the vehicle interior outer end portion 11P of the first armrest member side upper surface portion 11 is inserted is provided in the vehicle interior outer wall 56 of the armrest recess 55 which is a part of the door trim. Note that the length in the vehicle width direction of the first armrest member side upper surface portion 11 is always inserted into the insertion hole 51 when the passenger compartment outer end portion 11P is in the housed state and the bulged state of the first armrest member 10. It is set to be a configuration.

Then, the movement aspect of the 1st armrest member 10 is demonstrated.
When air flows into the bag main body 75 from the air inlet 77 by the operation of the actuator, the bag main body 75 expands and the entire air bag 70 pushes the first armrest member 10 toward the vehicle interior side, and the first The 1 armrest member 10 is in an expanded state (the expanded state of the air bag 70, see FIG. 4). Accordingly, each guide pin 30 provided in the first armrest member 10 also slides in each guide hole 30H of the second armrest member 20 in the vehicle interior side along the standing direction of the guide pin 30. At this time, the tip 39 of each guide pin 30 moves toward the vehicle interior side, so that the spring 60 disposed on the pin 30 contracts with the back surface 22B of the second armrest member side vehicle interior side surface portion 22. Is done.

  In addition to such sliding of the guide pins 30 toward the vehicle interior side, the locking portions 40 provided on the first armrest member 10 are moved in the slide rails 44 provided on the second armrest member 20. By sliding in the indoor side direction, the movement of the first armrest member 10 in the vehicle interior side direction is accurately guided. Since the air bag 70 and the first armrest member 10 have a longitudinal shape, if unevenness occurs in the way in which the bag body 75 swells when air flows in, the first armrest member 10 tends to rattle when the first armrest member 10 bulges. With such a configuration, the first armrest member 10 can be moved relatively smoothly in a substantially horizontal direction without being affected by how the bag body 75 swells.

  Moreover, since each latching | locking part 40 is latched by each guide rail 44 in the state which suppressed the movement to the up-down direction of the 1st armrest member 10, the swelling process and the bulging state of the 1st armrest member 10 are carried out. In this case, undesired movement of the first armrest member 10 to the upper side of the vehicle is restricted. Further, since the air bag 70 has a bag shape, as shown in FIG. 4, in the inflated state, the substantially center in the vertical direction is the back surface 12B of the first armrest member side vehicle interior side surface portion 12 and the second armrest member side. The vehicle interior side surface portion 22 is almost in a hit state. In such a point-scoring state, the posture of the first armrest member 10 supported by the air bag 70 tends to be unstable, but the first armrest member is caused by the guide pins 30 and the locking portions 40 described above. Ten stable postures can be maintained.

  On the other hand, when a valve (not shown) in the actuator is opened and the air in the air bag 70 gradually escapes, the first armrest member 10 is pulled in the vehicle cabin outside direction by the elastic return of each spring 60 and enters the housed state ( The contracted state of the air bag 70. See FIG. Even during the housing, the guide pins 30 and the locking portions 40 accurately guide the movement of the first armrest member 10 toward the outside of the passenger compartment, similarly to the time of inflation (when the air bag 70 is inflated). Will be. Further, the action of each locking portion 40 to restrict undesired movement of the first armrest member 10 to the upper side of the vehicle in the housing process and the housing state of the first armrest member 10 is the same as that at the time of swelling.

<Action and effect>
According to the armrest 50 as described above, the armrest 50 is provided on the back surface 12B of the armrest side surface (first armrest member side vehicle interior side surface portion 12) so as to follow the relative movement direction (vehicle width direction) of the first armrest member 10. Provided on the guide pin 30 (31, 32, 33, 34) and the back surface 11B of the armrest upper surface portion (first armrest member side upper surface portion 11) in a state allowing the movement of the first armrest member 10 in the relative movement direction. The relative movement direction of the first armrest member 10 can be more reliably guided by the locking portions 40 (40A, 40B, 40C). Moreover, since the latching | locking part 40 (40A, 40B, 40C) is also the structure latched in the state which suppressed the movement to the up-down direction of the 1st armrest member 10, the 1st armrest member 10 is the 2nd armrest member 20. On the other hand, it is possible to restrict movement in the vertical direction while being relatively movable in the vehicle width direction. As described above, in the configuration in which the first armrest member 10 is relatively moved by the expansion / contraction function of the air bag 70 disposed between the first armrest member 10 and the second armrest member 20, the guide pins 30 (31, 32) are used. , 33, 34) and the locking portion 40 (40A, 40B, 40C), the upper surface on the side of the first armrest member constituting the elbow rest surface without being affected by the bias of the air bag 70 inflating or shrinking. The first armrest member 10 including the portion 11 can be moved smoothly in the vehicle width direction, and the first armrest member 10 can be smoothly moved while restricting unwanted movement in the vertical direction.

  In addition, since an elastic member 60 that elastically deforms in the relative movement direction of the first armrest member 10 is interposed between the first armrest member 10 and the second armrest member 20, the air bag 70 is formed by the elastic member 60. The first armrest member 10 can move smoothly in the direction toward the outside of the passenger compartment.

  Further, a vehicle compartment outer side wall 56 in the armrest recess 55 which is a part of the door trim 100 is provided with a vehicle compartment outer side end portion 11P in the armrest upper surface portion (first armrest member side upper surface portion 11) of the first armrest member 10 which is relatively moved. Since the first armrest member 10 is configured to move relatively in the direction toward the passenger compartment, the passenger compartment in the armrest upper surface portion 11 is in the expanded and contracted state. Since no gap is generated between the outer end portion 11P and the vehicle interior outer wall 56, the design of the entire door trim 100 can be maintained.

  The armrests exemplified in the above embodiments are not limited to vehicles such as automobiles, but are trains and play vehicles as ground vehicles, airplanes and helicopters as flight vehicles, ships and submersibles as marine and underwater vehicles. It can be mounted on various vehicles.
