Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to an armrest device for a motor vehicle, which includes an armrest member that is tiltable and whose height can be adjusted.

PRIOR ART Armrest devices for automobiles on which the occupants can rest their elbows have been well known so that occupants can maintain a comfortable posture. Adjustable armrest devices are also already known.

However, conventional devices of this type have a drawback in that the mechanism for adjusting the height position of the armrest member and tilting it, as well as the operation thereof, are complicated, and improvements have been desired for some time.

Purpose This invention was made based on the above recognition,
It is an object of the present invention to provide an armrest device of the type mentioned at the outset, which is simple in structure and operation and low in cost.

Configuration In order to achieve the above object, the present invention comprises two racks arranged at a distance from each other and each driven vertically by a separate reversible motor, and a rack pivotally attached to the upper part of the rack. The rack and the armrest member are pivotally connected so that when one rack is raised or lowered, the armrest member can rotate around a pivot joint between the other rack and the armrest member. We propose the configuration of an armrest device.

Embodiments Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 shows an armrest device 2 mounted on a door 1 of a motor vehicle, which device 2 has a support 3 fixed to the door 1 and an armrest member 4 located above it.

The support 3 has a hollow interior as shown in FIGS. 2 and 3, and has two racks 7, 7a slidable in the vertical direction through holes 6, 6a in the upper wall 5. is inserted, and the upper part of each rack 7, 7a projects outside the support. Both racks 7,7
a are spaced apart from each other.

Also, the armrest member 4 shown as an example in the figure
is composed of a core material 8 made of a rigid body and a cushion material 9 with a skin fixed thereon, and the above-mentioned two racks 7,
The upper part of 7a is pivotally connected via pins 10 and 10a. At this time, the hole 11 of the rack 7 into which one of the pins 10 fits is a long hole, and the pin 10 fitted into the core member 8 can slide inside this long hole 11 in the longitudinal direction. ing.

Inside the support 3 are two reversible motors 1.
2, 12a are fixed, and worm gears 13, 13a are fixed to their respective output shafts, and worm wheels 14, 14a that mesh with each worm gear 13, 13a are connected to brackets 15, 15a fixed to the support 3. It is fixed to rotating shafts 16, 16a which are rotatably supported. Further, pinions 19, 19a are fixed to these rotating shafts 16, 16a, respectively.
are meshed with the teeth of each rack 7, 7a, respectively.

When the reversible motors 12, 12a are inactive, the armrest member 4 also stands still, allowing the occupant to rest his or her elbows on it and take a comfortable posture.

When adjusting the height position of the armrest member 4 according to the occupant's physique or preference, the occupant simultaneously operates both motors by pressing a switch (not shown) for the two reversible motors 12, 12a. . At this time, the pinions 19, 19a are driven to rotate in opposite directions, for example, the pinion 19a on the left side (front side of the automobile) in FIG.
When rotating clockwise in the figure, the other pinion 19 is rotated counterclockwise. As a result, racks 7, 7a and armrest member 4
can be translated upward or downward to adjust the armrest member 4 to a desired height. By stopping the operation of the reversible motors 12, 12a, the armrest member 4 can be fixed at a desired position, and the elbow can be placed on it without any problem.

When tilting the armrest member 4, for example, only the switch (not shown) for the reversible motor 12a on the left side of FIG. 2 is operated to operate only the motor 12a and rotate the pinion 19a clockwise. As a result, only one rack 7a is raised, and the armrest member 4 is tilted as shown by the chain line in FIG. In this case, the hole 11 at the pivot point between the other rack 7 and the armrest member 4 is a long hole, and the pin 1
Since the armrest member 4 can move through the elongated hole 11, the armrest member 4 can be tilted smoothly without any trouble.

By reversing the rotational direction of the reversible motor 12a, the armrest member 4 can be returned to the horizontal state shown by the solid line in FIG.

Of course, it is also possible to operate only the other reversible motor 12 to move the rear end side (the right end side in FIG. 2) of the armrest member 4 up and down.

In the above embodiment, the hole 11 of the rack 7 is made into a long hole, so that when one rack 7 or 7a is raised or lowered, the armrest member 4 is pivoted between the other rack 7a, 7 and the armrest member 4. However, the hole 11 of the rack 7 has a mating hole, that is, the hole formed in the core material 8, is made into a long hole, or the pin 10a of the rack 7a is fitted. The same function can be obtained by using the hole formed in the core material 8 or the hole formed in the core material 8 as a long hole.

It goes without saying that the present invention can be applied not only to automobile doors but also to armrest devices provided on vehicle bodies, seats, and the like.

Effects According to the present invention, it is possible to provide an armrest device that is not only simple in structure but also easy to operate and is low in cost.
