Description

[Detailed Description of the Invention] [Industrial field of application] The present invention is a position display device for a slide rail that is mounted on a slide rail that moves the seat back and forth and sets the front and rear positions of the seat, and displays the position. Regarding

[Prior Art] In a seat of a vehicle or the like, a slide rail that allows the seat to move forward and backward and sets a seated passenger's favorite position so that the front and rear positions can be adjusted according to the body shape and taste of the seated person It is provided.

As the slide rails, for example, a pair of upper rails that are separated from each other left and right and fixed to the lower surface of the seat cushion, and fixed to the floor surface of the vehicle facing the upper rails.
A configuration including a pair of lower rails slidably supporting the upper rail is well known.

In a known slide rail, for example, a swingable operation lever having a lock piece formed at one end is attached to an upper rail, and a series of engageable lock holes of a lock piece of the operation lever is provided on, for example, a lower rail. It is formed on the fixed lock plate at a predetermined pitch. Then, the occupant operates the operation lever to move the lock piece away from the lock hole, and then moves the seat to lock the slide rail by engaging the lock piece and the lock hole at the optimum position of the seat. , Set the optimal front and rear position of the seat.

[Problems to be solved by the device]

However, since the known slide rail is arranged on the lower surface of the seat, it is difficult to accurately determine the lock position of the slide rail, that is, the position of the seat, visually. Therefore, the seated person relies on his or her own sense to set the optimum position of the seat.

Here, in a car driven by a plurality of drivers, for example, a car owned by a company or a car shared by a family, the seat is located at an optimum position for each driver.
It is set each time. In other words, even if the optimum position is set once, the position will be changed by another driver, and the driver must reproduce the position of the seat to the optimum position each time the driver drives the vehicle.

However, the seat position is set only by the judgment of the driver. In other words, even when the optimum position of the seat is reproduced, it is set only by the driver's feeling, so the optimum position of the seat cannot be easily reproduced and the seat may be set at a position slightly deviated from the optimum position. is there. In such a case, the work of setting the position of the seat is repeatedly performed, or the vehicle is operated while being deviated from the optimum position. In particular, when the seat is set out of the optimum position, the driver drives while feeling uncomfortable with the seat, which may distract the driver's attention and hinder safe driving, which is not preferable.

The present invention aims to provide a slide rail position display device that allows a driver to visually judge and optimally and quickly reproduce the optimum position of a seat.

[Means for Solving the Problem] In order to achieve this object, according to the present invention, a slide switch as a position detecting means for detecting the lock position of the slide rail is provided between the upper rail and the lower rail. There is.

The slide switch includes a plurality of released fixed contacts and a movable contact fixed to the slider, and the slider slides in the slide switch body in conjunction with the upper rail. Therefore, when the movable contact slides with the slider and sequentially contacts each fixed contact, the pair of fixed contacts is short-circuited.

The sequence circuit is set for each position of the fixed contact, and when the fixed contact is short-circuited, the signal of the sequence circuit is output to the display unit to display the lock position on the display unit.

〔Example〕

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

As shown in FIGS. 1 and 2, in the slide rail position display device 10 according to the present invention, the pair of slide rails 12 themselves disposed on both sides of the seat have a known structure. That is, the slide rail 12 includes an upper rail 14 for mounting a seat frame (not shown) together with a seat cushion and a lower rail 16 fixed to the floor surface of the vehicle. A steel ball 22 is juxtaposed between an inner flange 18 formed at the lower end of the upper rail 14 and an outer flange 20 formed at the upper end of the lower rail 16. Further, the roller 24 is arranged between the upper rail 14 and the lower rail 16. In the above configuration, the pair of steel balls 22, the upper rail 14,
The roller 24 bears the load in the horizontal direction between the lower rails 16 and the load in the vertical direction, so that the slide of the upper rail with respect to the lower rail is ensured.

In addition, a pin 30 installed between the side walls of the bracket 29 fixed to the side of the upper rail 14 allows the operation lever to be operated.
28 is swingably attached, and a lock piece 26 is provided at one end of the operation lever. And, for example, lower rail
The lock plate 34 fixed to the lower surface of the 16 is provided with a series of lock holes 32 capable of engaging the lock pieces, and the lock pieces of the operation lever.
It is formed so as to face 26 and be separated by a predetermined pitch. Here, for example, a biasing means (not shown) such as a torsion spring so as to bias the lock piece 26 toward the lock hole 32.
Is provided on the operation lever 28. Then, the lever lock piece 26 provided on the upper rail 14 and the lower rail
By engaging with the lock hole 32 of the lock plate provided in 16, the slide rail 12 is locked at an appropriate position and the seat position is set.

Then, for example, the position detecting means 36 is fixed to the extending end 34a formed integrally with the lock plate 34. As the position detecting means 36, for example, a slide switch can be used, and the slide switch includes a slide switch body 38 and a slider 40 slidable in the slide switch body. The slide switch body 38 is formed, for example, in a substantially U-shape, and has an elongated hole 42 formed in the upper surface. Then, in the opening of the slide switch body 38, a board 4 having a pair of fixed contacts 44, 45
8 is stuck. As shown in FIG. 3, the pair of fixed contacts 44 and 45 correspond to the lock holes 26 formed in the lower rail 16 of the slide rail at the same pitch, for example, 9
Row, installed. Also, the slider 40 has a pin 50 on the upper end, and this pin is a long hole of the slide switch body.
It is loosely fitted in the slide switch 42 and is disposed in the slide switch body 38. Then, the pin 50 of the slider is, for example, the hole 53 of the support plate 52 fixed to the upper surface of the upper rail.
Is loosely fitted to. Further, the slider 40 has a movable contact 54 on the surface facing the pair of fixed contacts 44, 45 so as to contact the fixed contact and short-circuit the pair of fixed contacts. With such a configuration, the slider 40 slides in the slide switch body 38 integrally with the upper rail 14 of the slide rail. The movable contact 54 of the slider is fixed contacts 44-1 to 44-9, 45-1 to 45-9 of the slide switch body 38.
And the pair of fixed contacts are short-circuited at each position. Here, in order to ensure the contact between the fixed contacts 44, 45 and the movable contact 54, for example, a spring 55 may be arranged in the slider 40 so that the movable contact is always biased in the fixed contact direction. preferable. As the spring 55, for example, a compression coil spring can be used.

As can be seen clearly from FIG. 4, for example, each fixed contact 44 is connected with a sequence circuit 56 which outputs a signal corresponding to each position. The fixed contact 45 is connected to a display unit 58 that displays the signal output from the sequence circuit 56, and the position of the fixed contact that the movable contact 54 contacts is displayed on the display unit. Here, it is preferable that the sequence circuit 56 is connected to the battery via the ignition switch 60, and the voltage is applied by turning on the ignition switch. The display unit 58 is preferably provided at a position where the driver can easily confirm it, that is, on an instrument panel (instrument panel) 62 as shown in FIG. Also, as the display unit 58,
For example, a seven segment fluorescent tube digital display can be used, and each position can be displayed numerically.

As shown in FIGS. 3 and 4, in the slide rail position display device 10 having such a configuration, the lock hole 32 is provided.
Is assumed to be 1, 2, 3, ... From the left, and accordingly, it is assumed that the numbers corresponding to the position numbers are preset in order from the sequence circuit 56-1. Then, it is assumed that the lock piece 26 is engaged with the lock hole 32-5 and the movable contact 54 of the slider comes into contact with the fixed contacts 44-5 and 45-5 to short-circuit them. In such a state, the voltage is applied to the sequence circuit 56-5, and the signal preset in the sequence circuit 56-5 is output to the display unit 58 via the movable contact 54. Then, the sequence circuit output to the display unit 58
For example, “5” is displayed on the display unit 58 by the signal 56-5, and the position of the seat is clarified. Also,
From this state, when the lock pieces 26 and the lock holes 32 are unlocked and the upper rail 14 is moved, the slider 40 is moved integrally with the upper rail and the movable contact 54
Is released from the fixed contacts 44-5, 45-5 to release the short circuit, and "5" displayed on the display unit disappears once. Then, for example, the lock piece 2 is inserted into the lock hole 32-6 shown in FIG.
Assuming that 6 is engaged, the slider movable contact 54 contacts the fixed contacts 44-6 and 45-6 to short-circuit them, and applies a voltage to the sequence circuit 56-6, as described above. Then, a signal preset in the sequence circuit 56-6 is output to the display unit 58, and, for example, “6” is displayed on the display unit by the signal of the sequence circuit 56-6. In other words, whichever position of the lock hole 32 the lock piece 26 is engaged with, the corresponding sequence circuit 56 will be used.
Is output to the display unit 58 and each position number is displayed on the display unit.

As described above, according to the present invention, the movable contact 54, which moves integrally with the slide rail 12, contacts the fixed contacts 44 and 45 to short-circuit them, so that the position of the slide rail is detected, An appropriate display is displayed on the display unit 58 in response to the signal from the sequence circuit 56 that operates. Therefore, the position of the slide rail is displayed on the display unit 58 for clarity. Then, for example, by having each driver memorize the number displayed on the display unit 58 at the optimum position for that driver,
The optimum driver position can be set quickly and easily. In other words, the lock of the slide rail can be visually judged not by the driver's feeling but by the display of the mechanically detected position. Therefore, the optimum position of the driver can be set quickly and easily, and the driver is relieved of the trouble of setting the position of the slide rail. Further, according to the slide switch 36 as described above,
The signal of the sequence circuit 56 is output to the display unit 58 and displayed on the display unit only by the movable contact 54 contacting the fixed contacts 44 and 45 without engaging the lock piece 26 with the lock hole 32. Therefore, the driver can recognize the position of the slide rail 12 while moving the seat, and can quickly and easily move to the position to be set. The slide rail position display device 10 having such a configuration
When used in a vehicle shared by a plurality of drivers, can be particularly effectively used.

In the embodiment, the position detecting means 36 is embodied as a slide switch, but the point is that the slide rail is
It suffices that the sequence circuit 56 be sequentially switched depending on each of the 12 positions, and the present invention is not limited to this. For example, the position detecting means 36 may be configured by combining a slider 40 that moves integrally with the upper rail 14 and a micro switch fixed to the lower rail 16 corresponding to the lock hole 32. Further, the position detecting means 36 may be configured using a photo sensor. The display on the display unit 58 is a number indicating the position number of the slide rail, but the present invention is not limited to this.
It suffices if the position of can be clearly judged, and it may be displayed by the change of the alphabet or color, or the shading. Further, in the embodiment, the numbers of the lock holes 32 and the fixed contacts 44, 45, that is, the positions of the slide rails 12 are embodied as nine, but the number is not limited to this.

The above-described embodiments are for explaining the present invention, and are not intended to limit the present invention in any way, and all modifications and alterations within the technical scope of the present invention are also included in the present invention. Needless to say.
