Description

  The present invention relates to an armrest device, and more particularly to an armrest device provided with an armrest main body that can move to an appropriate position in accordance with the posture of an occupant.

Conventionally, an armrest for supporting the vicinity of an occupant's elbow portion and maintaining a comfortable posture is mounted in the passenger compartment.
However, the occupant's body shape varies from person to person. For example, the size may differ greatly between adults and children, women and men.
In this case, if the armrest is fixed, if the armrest does not match the occupant's body shape, there is a possibility that the armrest may get in the way or a comfortable posture cannot be maintained.

  In order to solve such a problem, it can be stored when not in use, and can appear when used, and its position can be adjusted according to the occupant's body shape, posture, usage situation, etc. An armrest device that can be used has been proposed (see, for example, Patent Documents 1 to 6).

Patent Document 1 discloses an armrest provided in a rear seat.
The armrest is stored in a storage portion formed on the seat back when not in use, and can be developed from the storage portion when in use.
The armrest is divided into a front part and a rear part, and the length in the front-rear direction can be adjusted by pulling out the front armrest with respect to the rear armrest.
Patent Document 2 also discloses an armrest whose length can be adjusted in the front-rear direction as in Patent Document 1.

Patent Document 3 discloses an armrest for an automobile seat.
This armrest is configured so that it can be folded when not in use, and can be deployed and used when in use.
The armrest is disposed on a guide rail extending in the vertical direction so as to be slidable in the vertical direction, and the armrest is moved up and down by driving a motor by a switch operation.
Patent Document 4 and Patent Document 5 also disclose an armrest whose height can be adjusted in the vertical direction as in Patent Document 3.

Furthermore, Patent Document 6 discloses an armrest.
The armrest is divided into two parts by a diagonal line, and is divided into a lower member and an upper member having a substantially right triangle shape in cross section.
The lower member and the upper member are coupled by a pair of link members. When the upper member is moved along the inclined surface that is the laminated surface of the lower member via the link member, the upper member is inclined upward. It is configured to overhang.
That is, the upper member is displaced obliquely upward, and the arm placement surface of the armrest is simultaneously displaced in the front-rear direction and the up-down direction.

However, in the techniques disclosed in Patent Documents 1 to 5, the armrest can move only in the front-rear direction or the vertical direction, and cannot flexibly cope with the physique and posture of the occupant.
In addition, there is a problem that the operability is not good because of the stage switching.
Furthermore, in the technique disclosed in Patent Document 6, although the armrest moves slightly in both the front-rear direction and the up-down direction, the range of motion is limited due to its structure, and it is flexible to the physique and posture of the occupant. It ’s hard to say that it ’s enough.
Further, the range of movement in the front-rear direction is considerably small due to the structure.

  An object of the present invention is to solve the above-mentioned problems, and it is possible to store it when not in use and to perform a stepless adjustment that can sufficiently displace the position in the front-rear direction and the up-down direction during use. The present invention relates to an armrest device.

  An object of the present invention is to provide an armrest device for a vehicle according to the present invention. The armrest device is held on a seat in a vehicle and is deployed when used, and the armrest device is a movable armrest that supports a part of an occupant's arm. A drive mechanism unit that drives the armrest movable unit, a connecting member that couples the drive mechanism unit and the armrest movable unit, and an armrest support unit that supports the drive mechanism unit and the armrest movable unit. The drive mechanism portion pushes the armrest movable portion to the front side of the vehicle and moves it to the upper side of the vehicle by moving the connecting member obliquely upward to the vehicle front side. It is solved by moving in a stepless manner.

As described above, in the present invention, the drive member moves the connecting member diagonally upward on the front side of the vehicle, so that the armrest movable portion connected to the connecting member is expanded diagonally upward on the front side of the vehicle.
Since it is configured in this way, the armrest movable part can be pushed forward and the vehicle can be moved upward with a single drive source at the same time, and the armrest movable part is moved steplessly. be able to.
Moreover, the movement range of the armrest movable part can be sufficiently secured, and the occupant's physique and posture can be flexibly dealt with.

The pinion gear meshes with the rack gear, and when the pinion gear rotates, the rack gear moves obliquely upward on the front side of the vehicle, and the armrest movable portion connected to the rack gear is It is preferable to be configured to be pushed out to the front side of the vehicle and to be continuously moved to the upper side of the vehicle.

If comprised in this way, the rotation output from the motor which is a drive source can be converted into a linear motion, and can be transmitted by the combined motion of a pinion gear and a rack gear.
Therefore, the rotation output from the motor is converted into a linear motion, the rack gear as a connecting member is moved obliquely upward on the front side of the vehicle, and the armrest movable portion connected to the rack gear is linearly moved to the front side of the vehicle and the upper side of the vehicle. Can be exercised steplessly.

  Further, at this time, a slide member is disposed in the armrest movable portion, and a slide hole that is aligned with a movable locus of the armrest movable portion is formed on a side surface of the armrest support portion. The member is slidably disposed in the slide hole, and the armrest movable unit is guided to draw a predetermined locus when the slide member slides on the slide hole. It is preferable.

If comprised in this way, since an armrest movable part can slide along a slide hole, it can move to a predetermined locus image stably.
For this reason, an armrest movable part can be moved smoothly, without generating rattling and noise.

Further, at this time, the slide hole forms an obtuse angle with the horizontal slide portion from the horizontal slide portion extending in the direction in which the armrest movable portion is pushed out, and the armrest movable portion moving side end portion of the horizontal slide portion. And an oblique slide portion that extends.
For this reason, the slide hole is formed in a substantially square shape, and the armrest movable portion draws a track along the substantially square shape.
Therefore, the trajectory can perform a so-called push-out operation and ascending operation simultaneously.
For this reason, it is possible to execute both operations with a single drive mechanism.
Further, by changing the length of the oblique slide portion and the angle of the oblique slide portion formed with the horizontal slide portion, the pushing movement distance and the height adjustment distance of the armrest movable portion can be easily changed.
Therefore, variations can be easily increased according to the vehicle type and seat on which the armrest device is mounted.

  Further, at this time, the armrest device is stored in a recess formed in the seat, and the drive unit detects that the armrest device is pulled out from the recess, and the armrest movable unit is moved to the armrest device. Pushing forward in the vehicle, waiting in the middle of reaching the fully deployed position, and receiving the ascent command, the armrest movable part is moved up to the vehicle forward and moved to the fully deployed position. It is preferable to be configured.

  Since it is configured in this way, the armrest movable part is automatically pushed out to a certain position when it is pulled out from the recess, and further height adjustment can be performed if necessary by giving an ascent command. it can.

  Further, at this time, the armrest movable portion is provided with a slide member, and the side surface of the armrest support portion is aligned with the movable locus of the armrest movable portion and extends in the direction in which the armrest movable portion is pushed out. A slide hole having a horizontal slide portion and an oblique slide portion extending at an obtuse angle with the horizontal slide portion from an end portion of the horizontal slide portion on the moving side of the armrest movable portion is formed. The slide member is slidably disposed in the slide hole, and the armrest movable portion is guided so as to draw a predetermined locus by sliding the slide member on the slide hole, The armrest device is housed in a recess formed in the seat, and the drive unit is pulled from the recess by the armrest device. When the armrest movable part is detected, the armrest movable part is pushed out to the front side of the vehicle, waits in the middle of reaching the fully deployed position, and when the ascent command is received, the armrest movable part is moved forward of the vehicle. The vehicle is moved up to the fully deployed position while being lifted upward, and the midway point is a point where the slide member has reached the substantially central part of the oblique slide part, so-called an average appropriate position. It is suitable because it can be automatically developed and fine adjustment can be performed by giving a command if necessary.

  Further, at this time, if the slide hole is configured to be formed on the side surface of the armrest support portion in parallel with the direction in which the armrest movable portion is pushed out, the armrest movable portion is reliably guided. This is preferable.

According to the present invention, by moving the connecting member obliquely upward on the vehicle front side by the drive mechanism, the armrest movable portion connected to the connecting member is developed obliquely upward on the vehicle front side.
Since it is configured in this way, the armrest movable part can be pushed forward and the vehicle can be moved upward with a single drive source at the same time, and the armrest movable part is moved steplessly. be able to.
Moreover, the movement range of the armrest movable part can be sufficiently secured, and the occupant's physique and posture can be flexibly dealt with.
Therefore, it is possible to provide an armrest device with a simple configuration that can be stored when not in use and that can sufficiently displace the position in the front-rear direction and the up-down direction when in use.

The rack gear 33 is supported by a rack gear restraining member G that spans the central axis M and the guide wall 22.

The movement of the armrest device S according to the present embodiment will be described with reference to FIGS.
As shown in FIG. 3, the armrest device S according to the present embodiment can be stored in a recess R <b> 1 formed in the central portion of the backrest of the rear seat R.

When the armrest device S is unnecessary, the occupant can use the seat surface widely by storing the armrest device S in the recess R1.
When the armrest device S is necessary, the armrest device S can be pulled out on the seat surface by tilting the armrest device S in the direction of the arrow 1.

  In addition, a proximity switch K1 is disposed on the surface of the recess R1 of the rear seat R facing the armrest movable portion 1, and in the vicinity of the boundary with the backrest of the seat surface of the rear seat R (when the armrest movable portion 1 is deployed). A proximity switch K2 is disposed at a position (covered by the armrest movable portion 1).

When the armrest device S is pulled out from the recess R1 of the rear seat R, a signal is detected from the proximity switch K1 by a controller (not shown) (detecting the falling of the signal).
In response to this signal, the controller drives the motor 31 to deploy the armrest movable unit 1 to the standby position.
The “standby position” is a position when the guide pins 13a and 13a reach the position provided at the standby point F (the midpoint of the oblique slide portion 22b) of the slide guide 22A.

Next, the armrest movable portion 1 of the armrest device S can be moved in the arrow 2 direction by rotating the motor 31 of the drive mechanism portion 3 in the forward direction or the reverse direction by an operation switch (not shown).
That is, the position of the armrest movable part 1 can be finely adjusted by this switch operation.

At this time, the switch is composed of, for example, a swing-type switch that can be operated in two steps, and is disposed at a position (for example, the rear seat side door trim, the center portion of the seat surface of the rear seat R, etc.) that can be operated by a passenger in the vehicle interior. It is installed.
This operation switch has a deployment switch, a return switch, and an auto switch. When the occupant operates the operation switch, a command signal for operating the armrest device S is output to a controller (not shown).

Specifically, when the operation switch is operated to one end side by one step, the expansion switch is turned on, and a normal expansion command signal for causing the armrest device S to perform a normal expansion operation (that is, the expansion operation only during the operation). Output to the controller.
Further, when the operation switch is operated in one step toward the other end, the return switch is turned on, and a normal return command signal for causing the armrest device S to return to the normal position (that is, return to the standby position only during operation). Is output to the controller.

Further, when the operation switch is operated in two steps toward one end, both the expansion switch and the auto switch are turned on, and the automatic operation for causing the armrest device S to perform the automatic expansion operation (that is, the expansion operation to the full expansion position even if the operation is stopped). Outputs a deployment command signal to the controller.
Further, when the operation switch is operated in two steps toward the other end, both the return switch and the auto switch are turned on, and the auto switch for automatically returning the armrest device S (that is, returning to the standby position even if the operation is stopped) is performed. Outputs a close command signal to the controller.

While receiving the normal deployment command signal from the operation switch (while the operation switch is being operated), the controller drives the motor 31 in the forward direction via the drive circuit to cause the armrest device S to perform the normal deployment operation. .
On the other hand, the controller drives the motor 31 in the reverse direction via the drive circuit while receiving the normal return command signal from the operation switch (while the operation switch is operated), and moves the armrest device S to the standby position. Until normal recovery is performed.

Further, when the controller receives an auto-deployment command signal from the operation switch, the controller drives the motor 31 in the forward direction via the drive circuit and causes the armrest device S to auto-deploy to the fully deployed position.
On the other hand, when the controller receives an automatic return command signal from the operation switch, the controller drives the motor 31 in the reverse direction via the drive circuit to cause the armrest device S to automatically return to the standby position.

Further, when the armrest device S is pulled up from the standby position in the direction of the recess R1, a signal is detected from the proximity switch K2 by a controller (not shown) (detection of the fall of the signal).
In response to this signal, the controller drives the motor 31 in the reverse direction to return the armrest movable portion 1 so that it can be stored in the recess R1.

FIG. 4 shows the state at the full return position.
In this state, when the armrest device S is pulled out from the recess R1 of the rear seat R to the seating surface, the motor 31 is driven, and the armrest movable portion 1 of the armrest device S starts to expand in the direction of the arrow, that is, the vehicle front direction.
When the armrest movable unit 1 is further expanded by the switch operation after waiting once at the standby position, the armrest movable portion 1 is expanded to the entire expansion position of FIG.

FIG. 5 shows a state at all deployment positions.
Thus, in this state, the armrest movable portion 1 protrudes toward the vehicle front side and rises upward in the vehicle.
In this state, when the switch is operated in the return direction, the motor 31 is driven in the reverse direction, and the armrest movable unit 1 starts to return to the standby position while descending in the vehicle rearward direction.
When the armrest device S is lifted from the seating surface, the motor 31 is driven in the reverse direction, and the armrest movable unit 1 returns to the full return position (that is, the state shown in FIG. 4).

Next, the movement of the drive mechanism unit 3 will be described with reference to FIGS.
6 is an explanatory diagram of the position of the armrest movable unit 1 before deployment, FIG. 7 is an explanatory diagram of the standby position, and FIG. 8 is an explanatory diagram of the fully deployed position.

FIG. 6 is a view showing a state in which the armrest device S is pulled out from the recess R1.
At this time, the armrest movable part 1 is not developed.
A worm gear 32a is connected to the output shaft of the motor 31, and the worm gear 32a meshes with the worm wheel 32b. Power is transmitted to a pinion gear 32c provided coaxially with the worm wheel 32b (center axis M). Thus, the speed reduction part 32 is configured.

The pinion gear 32c meshes with teeth formed at the vehicle front side end portion of the linear rack gear 33.
A rack shaft 33a is formed at the vehicle upper end of the rack gear 33. The rack shaft 33a is pivotally supported by a rack support member 11A formed on the inner side of the top surface of the armrest movable portion 1. ing.
The rack gear 33 is supported by a rack gear restraining member G spanning the central axis M and the guide wall 22 so as not to swing in the vehicle width direction.

In this state, when the armrest movable part 1 is pulled out from the recess R1 of the rear seat R and the motor 31 rotates in the forward direction, this rotational output is transmitted to the worm gear 32a, the worm wheel 32b, and the pinion gear 32c.
In response to this transmission, when the pinion gear 32c rotates in the direction of the arrow, the rack gear 33 is sent out in the direction of the arrow.

As the rack gear 33 moves, the armrest movable unit 1 connected to the rack gear 33 via the rack support member 11A starts to expand in the same direction.
At this time, the guide pins 13a and 13a formed on the inner wall of the side surface 13 of the armrest movable portion 1 also move in the same direction. The guide pins 13a and 13a are slide guides 22A formed on the guide wall 22. , 22A, the guide pins 13a, 13a move along the slide guides 22A, 22A.
That is, the armrest movable part 1 moves along a locus along the shape of the slide guides 22A and 22A.

FIG. 7 shows a state where the armrest movable unit 1 is in the standby position.
Thus, as the rack gear 33 is moved by the drive of the motor 31 and the guide pins 13a and 13a are moved along the slide guides 22A and 22A, the armrest movable portion 1 has the shape of the slide guides 22A and 22A. It moves by drawing a trajectory along.

The state where the guide pins 13a and 13a have reached the standby point F that is the midpoint of the oblique slide portion 22b of the slide guides 22A and 22A is the standby position.
When the motor 31 is further rotated forward by the switch operation at this standby position, the guide pins 13a and 13a are further raised along the oblique slide portions 22b of the slide guides 22A and 22A, and the armrest movable portion 1 is further moved forward of the vehicle. Continue to expand while rising in the direction.

FIG. 8 shows a state in which the armrest movable unit 1 has completely reached the deployed position.
Thus, in the deployed position, the pinion gear 32c meshes with the vehicle rear side end portion of the rack gear 33, and the guide pins 13a and 13a are disposed at the upper end portions of the slide guides 22A and 22A.

Since the oblique slide portion 22b of the slide guides 22A and 22A is inclined upward in the vehicle, the armrest movable portion 1 is pushed forward along the slide portion 22b and lifted upward in the vehicle. To do.
Further, when the armrest device S is lifted from the seating surface, the motor 31 rotates in the reverse direction, follows the reverse path, and moves while descending to the vehicle rear side.

The operation from the standby position to the fully deployed position can be performed by a switch operation by the occupant.
That is, the occupant can adjust the position (length and height in the vehicle front-rear direction) of the armrest movable unit 1 by operating the switch.
For this reason, the adjustment according to a passenger | crew's body shape, attitude | position, etc. can be performed finely.

Further, the armrest device S can be automatically operated by the proximity switches K1 and K2.
For this reason, a complicated operation is unnecessary and a highly convenient armrest device can be provided.

FIG. 9 shows the position displacement state of each member.
As shown in this figure, the guide pin 13a moves from the full return position X1 to the full deployed position X3.
After passing through the intermediate point X2, the armrest movable part 1 moves up while moving forward between the intermediate point X2 and the entire deployed position X3.

That is, the height is increased by H2.
Further, the position is adjusted between the standby point F and the entire deployed position X3 by a switch operation by the occupant.
That is, the height H1 can be adjusted by operating the switch.

FIG. 10 shows a configuration example of the slide guide 22A.
The armrest device S according to the present embodiment can change the movement of the armrest movable unit 1 by changing the configuration of the slide guide 22A.
As shown in FIG. 10A, when the angle formed by the oblique slide part 22b and the horizontal slide part 22a of the slide guide 22A is changed, the horizontal movement distance and the vertical movement distance of the armrest movable part 1 are changed.

That is, if the angle formed by the oblique slide portion 22b and the horizontal slide portion 22a is reduced (that is, θ ′ <θ), the armrest movable portion 1 is moved horizontally even if the oblique slide portion 22b has the same length. The distance decreases and the vertical movement distance increases.
That is, L2 ′ <L2 and H2 ′> H2.

Also, as shown in FIG. 10B, when the length of the oblique slide portion 22b is changed without changing the angle formed by the oblique slide portion 22b and the horizontal slide portion 22a of the slide guide 22A, the armrest The horizontal movement distance and the vertical movement distance of the movable part 1 change.
That is, when the length of the oblique slide portion 22b is increased, the horizontal movement distance and the vertical movement distance of the armrest movable portion 1 increase even if the angle formed by the oblique slide portion 22b and the horizontal slide portion 22a is the same. .
That is, L2 ″> L2 and H2 ″> H2.
At this time, in this embodiment, the standby point F is changed to the standby point F ″.

Of course, if the length of the horizontal slide portion 22a is increased, the horizontal movement distance of the armrest movable portion 1 increases, and if the angle is increased or the length of the oblique slide portion 22b is decreased, the phenomenon occurs. Is the opposite.
Moreover, the horizontal direction and the vertical direction of the armrest movable part 1 are increased / decreased by combining and increasing / decreasing the angle formed by the oblique slide part 22b and the horizontal slide part 22a and the lengths of the oblique slide part 22b and the horizontal slide part 22a. The amount of displacement can be adjusted as necessary.

  As described above, according to the armrest device S according to the present embodiment, the movement of the armrest movable unit 1 can be changed only by a simple configuration change, that is, only by changing the configuration of the slide guide 22A.
