  However, in the armrest described above, the position of the airbag is not regulated, and the height of the upper surface of the armrest is adjusted only by its expansion / contraction function. There is a risk of rattling when the upper surface is raised or lowered. In addition, when the airbag is repeatedly inflated and contracted, the mounting position is also displaced, and the smooth upward or downward movement of the upper surface of the armrest having the elbow rest surface may be hindered, and there is room for improvement. there were.

  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 attached to the second armrest member so as to be movable relative to the second armrest member in a vertical direction. The back surface of the upper surface of the armrest has a first armrest member facing the second armrest member. A plurality of guide pins extending in a direction following the moving direction is provided, and a locking portion for locking the first armrest member to the second armrest member is provided on the back surface of the armrest side surface portion. Guide holes through which the guide pins are inserted are respectively provided in the one opposing portion, and the locking portion is provided in the second opposing portion while allowing the first armrest member to move in the vertical direction. A locked portion that locks in a state in which movement in the width direction is suppressed is provided, and an inflatable and deflated air bag is disposed between the armrest upper surface portion and the first facing portion. It is characterized by.

  According to such a vehicle armrest, the guide pin provided in the direction following the relative movement direction (vertical direction) of the first armrest member on the back surface of the armrest upper surface portion, and the relative movement of the first armrest member on the back surface of the armrest side surface portion By the engaging portion provided in a state where the first armrest member is capable of being guided, the relative movement direction of the first armrest member in the vertical direction can be more reliably guided. Further, since the locking portion is also configured to lock in a state in which the movement of the first armrest member in the vehicle width direction is suppressed, the first armrest member can be moved relative to the second armrest member in the vertical direction. However, it is possible to restrict the movement in the vehicle width direction. Thus, in the structure which raises / lowers the 1st armrest member by the expansion / contraction function of the air bag arranged between the 1st armrest member and the 2nd armrest member, the inflation of the air bag is caused by the guide pin and the locking portion. Of the first armrest member that restricts the movement in the undesired vehicle width direction while guiding the vertical movement of the first armrest member provided with the elbow mounting surface without being influenced by the bias of the direction or the shrinkage. Smooth movement is possible.

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 FIG. 2, the armrest 50 includes a first armrest member 10 and a second armrest member 20 that is separate from the first armrest member 10 and supports the first armrest member 10 from below. It is configured. 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 vertical 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 guide pins 30 extending downward toward the second armrest member 20 are provided on the back surface 11B of the upper surface portion 11 on the first armrest member side, following the relative movement direction (the vehicle vertical direction) of the first armrest member 10. ing. 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 that is relatively disposed on the vehicle interior side and a guide pin 32 that is disposed on the vehicle exterior side of the guide pin 31. The rear guide pin 30R is also a pair of A pair of guide pins 33 relatively disposed on the vehicle interior side and guide pins 34 disposed on the vehicle exterior side of the guide pins 33 are paired. A plurality of locking portions 40 (40A, 40A, 40A, 40A, 40B) that lock the first armrest member 10 with respect to the second armrest member 20 are provided on the rear surface 12B (vehicle compartment outer surface) of the first armrest member side vehicle interior side surface portion 12. 40B, 40C). Each of the locking portions 40 is a member that can slide in the vertical direction within a slide rail 44 provided in the second armrest member 20, and is provided in three spaced apart from each other in the vehicle longitudinal direction (see FIG. 2). ).

  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). Guide holes 30H (31H, 32H, 33H, 34H) through which guide pins 30 (31, 32, 33, 34) provided in the first armrest member 10 are inserted correspond to the second armrest member side upper surface portion 21, respectively. In the position to be penetrated, it is formed to penetrate in the vertical direction.

  Each guide pin 30 (31, 32, 33, 34) is provided with a spring 60 in a state where the guide pin 30 is inserted into the corresponding guide hole 30H, and one end 62 of each spring is provided at one end 62. 30 is connected to the tip 39 in the standing direction. The length of each spring 60 is designed so that the spring 60 is in a steady state in the lowered state of the first armrest member 10 shown in FIG. That is, the length of each spring 60 in the steady state is the length of the portion of each guide pin 30 exposed below the back surface 21B of the upper surface portion 21 on the second armrest member side in the lowered state of the first armrest member 10. It is designed to be roughly equivalent. The position where the spring 60 is provided is not limited to this, and can be changed as appropriate.

  Further, slide rails 44 (44A, 44B, 44C) for locking locking portions 40 (40A, 40B, 40C) provided on the first armrest member 10 are provided on the side surface 22 of the second armrest member side vehicle interior side ( "Corresponding to" locked portions ") are provided at corresponding positions. Each slide rail 44 is provided so as to extend in the vertical direction, and the vehicle width that intersects the relative movement direction while allowing each locking portion 40 to move in the relative movement direction (vehicle vertical direction) of the first armrest member 10. It is set as the structure which latches in the state which suppressed the movement to a direction, respectively. That is, the first armrest member 10 is attached to the second armrest member 20 so as to be relatively movable in the vertical direction by the guide pins 30 and the locking portions 40 described above.

  Between the first armrest member 10 (first armrest member side upper surface portion 11) and the second armrest member 20 (second armrest member side upper surface portion 21), an inflatable and contractible air bag 70 is disposed. (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 to the bag main body portion 75 into which air flows is formed at a position that is substantially in the center in the longitudinal direction of the air bag 70 and that is outside the passenger compartment when it is disposed on the armrest 50 ( (See FIG. 2). On the other hand, an air inflow opening 57 is formed in the vehicle interior outer wall 56 of the armrest recess 55, so that 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.

Then, the movement aspect of the 1st armrest member 10 is demonstrated.
When air flows into the bag body 75 from the air inlet 77 by the operation of the actuator, the bag body 75 expands and the entire air bag 70 lifts the first armrest member 10 and the first armrest member 10 rises. The air bag 70 is in an inflated state (see FIG. 4). Accordingly, each guide pin 30 provided in the first armrest member 10 also rises while sliding upward in the vehicle along the standing direction of the guide pin 30 in each guide hole 30H of the second armrest member 20. . At this time, the tip 39 of each guide pin 30 rises, so that the spring 60 disposed on the pin 30 contracts with the back surface 21B of the second armrest member side upper surface portion 21. In addition to such upward sliding of each guide pin 30, each locking portion 40 provided on the first armrest member 10 slides inside the slide rail 44 provided on the second armrest member 20 upward in the vehicle. By doing so, the movement of the first armrest member 10 upward of the vehicle 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 is likely to rattle when the first armrest member 10 is lifted. With such a configuration, the first armrest member 10 is relatively moved upward in a substantially horizontal posture without being affected by how the bag body 75 swells, in a substantially uniform manner in the vehicle front-rear direction and the vehicle width direction. be able to.

  Moreover, since each latching | locking part 40 is latched by each guide rail 44 in the state which suppressed the movement to the vehicle width direction of the 1st armrest member 10, in the raising process and the raising state of the 1st armrest member 10 The undesired movement of the first armrest member 10 toward the vehicle interior side is restricted. Further, since the air bag 70 has a bag shape, as shown in FIG. 4, in the inflated state, the substantial center in the vehicle width direction is up and down, and the back surface 11B of the first armrest member side upper surface portion 11 and the second armrest member. It will be in the state which substantially hits each with respect to the side upper surface part 21. FIG. In such a point-scoring state, the posture of the first armrest member 10 supported from below by the air bag 70 tends to be unstable, but the first pin 30 and the locking portion 40 described above cause the first armrest member 10 to be unstable. The stable posture of the armrest member 10 can be maintained.

  On the other hand, when the valve (not shown) in the actuator is opened and the air in the air bag 70 is gradually removed, the first armrest member 10 that loses support from below is pulled downward by the elastic return of each spring 60 and is in a lowered state. (The contraction state of the air bag 70. See FIG. 3). That is, the first armrest member 10 is lowered by its own weight and the elastic return of each spring 60. Even at the time of the lowering, each guide pin 30 and each locking portion 40 accurately guide the movement of the first armrest member 10 to the lower side of the vehicle, similarly to the time of the rising (when the air bag 70 is inflated). Become. In addition, the action of each locking portion 40 to restrict undesired movement of the first armrest member 10 toward the vehicle interior side in the lowering process and the lowering state of the first armrest member 10 is the same as that at the time of ascent. .

<Action and effect>
According to the armrest 50 as described above, the guide pin 30 (31, 31) provided on the back surface 11B of the armrest upper surface portion (first armrest member side upper surface portion 11) in a direction following the relative movement direction of the first armrest member 10. 32, 33, and 34), and similarly provided on the back surface 12B of the armrest side surface portion (first armrest member side vehicle interior side surface portion 12) in a state allowing the movement of the first armrest member 10 in the relative movement direction. The relative movement direction (vertical direction) of the first armrest member 10 can be more reliably guided by the stop 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 vehicle width direction of the 1st armrest member 10, the 1st armrest member 10 is the 2nd armrest member 20 in it. However, it is possible to restrict movement in the vehicle width direction intersecting with the relative movement direction while being capable of relative movement in the vertical direction. In this manner, the guide pin 30 (31, 32, 33, 34) and the locking portion 40 (40A, 40B, 40C) are not affected by the bias of the air bag 70 inflating or shrinking, and the elbow While guiding the relative movement direction of the first armrest member 10 having the first armrest member side upper surface portion 11 constituting the placement surface, the movement of the first armrest member 10 in the vehicle width direction intersecting with the movement direction is regulated. The ideal movement of the first armrest member 10 can be realized.

  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.
