Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a vehicle seat device.
[0002]
[Prior art]
Vehicle seats are often slidable in the front-rear direction, and in particular, the rear row seats located behind the front row seats constituting the driver's seat and the passenger seat can be slid greatly in the front-rear direction. There is.
[0003]
In some cases, a long guide rail extending in the front-rear direction is used to guide a plurality of front and rear seats in the front-rear direction using the same guide rail (for example, Japanese Utility Model Publication No. 61-80132). The above publication also discloses that a plurality of front and rear seats can be double-faulted on the same (common) guide rail.
[0004]
[Problems to be solved by the invention]
When a plurality of front and rear seats are guided by the same guide rail, a slider is provided for each seat with respect to the guide rail so that the front and rear seats can be independently slidably adjusted. In this case, when each sheet is double-faulted, the minimum distance between the double-faulted sheets is when the front and rear sliders are closest to each other, but there is a limit to the proximity of the sliders (the same guide rail). Therefore, in relation to guiding a plurality of sliders, the state in which the sliders are in contact with each other in the front-rear direction is the closest), and there is a limit to reducing the space between the double-faulted sheets in the front-rear direction. This limits the expansion of the longitudinal length of the passenger compartment obtained by double faulting.
[0005]
The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a vehicle seat device in which a vehicle compartment can be greatly enlarged in the front-rear direction when a plurality of front and rear seats are double-faulted. Is to provide .
[0006]
[Means for Solving the Problems]
In order to achieve the above object , the following solution is adopted in the present invention. That is, as described in claim 1 in the claims,
In a vehicle seat device in which a plurality of front and rear seats are guided to be slidable in the front-rear direction by the same guide rail extending in the front-rear direction, and each of the front and rear seats can be double-faulted,
A number of sliders corresponding to the plurality of sheets are slidably held in the front-rear direction on the guide rail, and set so that one sheet is engaged with one slider,
At least one of the front and rear sheets is detachable from one slider corresponding to the one of the sliders, and the other slider is engaged with the other. Can be engaged,
The one sheet is detached from the one slider and engaged with the other slider so that the front and rear sheets can be double-faulted while being engaged with the other slider. It is. Preferred embodiments based on the above solution are as described in claims 2 to 5 in the claims.
[0007]
【The invention's effect】
According to claim 1, when a plurality of front and rear sheets are double-faulted, a plurality of sheets are double-faulted on one slider, so that the double-faulted state is achieved as compared with the case of double-faulting on each slider. The length in the front-rear direction of the plurality of sheets is sufficiently shorter than that in the prior art, and this loading chamber can be greatly expanded in the front-rear direction.
[0008]
Also, using the removal of the sheet from the slider, the removed sheet can be easily engaged with another slider for a double fault.
According to the second aspect , a plurality of double-faulted seats can be gathered forward in the vehicle compartment, and the cargo compartment formed behind the double-faulted seat can be enlarged in the longitudinal direction.
According to the third aspect of the present invention, the seat can be stably supported in the front-rear direction, which is the sliding direction, by engaging the seat with the slider at two front and rear positions. Further, by making the length between the front and rear engaging portions of the front slider longer than the thickness in the front and rear direction of the rear sheet when double-faulted, the double-faulted rear sheet can be stably and reliably placed on the front slider. Can be supported.
[0009]
According to the fourth aspect of the present invention, the seat can be stably supported in the front-rear direction, which is the sliding direction, by engaging the seat with the slider at two front and rear positions. In addition, the rear engagement portion of the front slider can be effectively used as a swing center when the rear seat is double-faulted on the front slider.
According to the fifth aspect , it is possible to prevent the front and rear double-faulted sheets from being inadvertently moved in the front-rear direction only by fixing one double-faulted sheet.

Note that the recess 56 is used as a foot space or as a container, depending on whether or not an occupant is seated on the second row seat 12 and the third row seat 13 or by changing the slide position in the front-rear direction. When the third row seat 13 is slid the most forward, the concave portion 56 is covered with the third row seat 13 and used exclusively as a container (not seated on the third row seat 13). In the case of using the back as a cargo room).
[0020]
The cross-sectional shape of the main body 54a in the guide rail 54 is as shown in FIG. 6, but the front and rear ends thereof are closed. A slit 54d extending in the front-rear direction is formed on the upper surface of the main body 54a, and the front and rear ends of the slit 54d are closed. A slider 61 is fitted and held in the main body 54a so as to be slidable in the front-rear direction. The slider 61 is integrated with the front locking pin 24 at the front end thereof, and is integrated with the rear locking pin 25 at the rear end thereof. Each locking pin 24, 25 constitutes a connecting portion between the locking metal fitting 22 and the slider 61, that is, the guide rail 54, and extends short in the vehicle width direction. The slider 62 is the same as the slider 61.
[0021]
The locking fitting 22 is formed with a locking recess 22a that opens downward, and the locking recess 22a is locked by bringing the locking fitting 22 close to the locking pins 24 and 25 through the slit 54d. The pins 24 and 25 are engaged. The details of the connecting portion with the locking pins 24 and 25 will be described with reference to FIGS. 8 and 9, focusing on the connecting portion with the locking pin 24, including the locking mechanism. In addition, the connection between the locking bracket 22 and the locking pin 25 is configured in the same manner as the connection portion between the locking bracket 22 and the locking pin 24. This means that the front and rear sliders 61 and 62 and the front and rear seats are connected. The same applies to the relationship with 12 and 13.
[0022]
First, a striker (locking member) 41 is rotatably held by a pin 42 in the locking metal fitting 22. When the locking pin 24 is engaged with the locking recess 22a and the striker 41 is rotated largely counterclockwise as shown in FIG. 8, the opening end of the locking recess 22a is released. Then, by disengaging the locking metal member 22 relative to the locking pin 24, the engagement between 22 (22a) and 24 can be released (lock release state). When the striker 41 is rotated largely in the clockwise direction as shown in FIG. 9 with the engagement pin 24 engaged with the engagement recess 22a, the opening end of the engagement recess 22a is the striker 41. The lock pin 24 is in a locked state in which it is impossible to disengage the lock pin 24 from the lock recess 22a.
[0023]
The striker 41 is urged toward the locked state shown in FIG. By manually operating the striker 41, for example, the unlocked state shown in FIG. In order to achieve this unlocked state, the cam plate 45 that is rotated according to the swing of the operation lever 44 that is manually operated is rotated by the mounting pin 46 with respect to the third row seat 13 (frame thereof ). It is held freely. A cam hole 45a is formed in the cam plate 45, and a pin member 47 that is slidably fitted in the cam hole 45a is fixed to the striker 41. The cam hole 45a is set so that the distance from the mounting pin 46 gradually changes along the circumferential direction.
[0024]
When the operation lever 44 is swung counterclockwise in FIG. 8, the cam plate 45 is swung counterclockwise in FIG. 8 about the mounting pin 46, and the striker 41 is counterclockwise in FIG. Is swung in the direction (movement in the unlocking direction). When the unlocking operation force is released from the operation lever 44, the spring 43 returns to the locked state shown in FIG. The operation lever 44 is linked to the front striker via a link mechanism or a linkage mechanism such as a wire, so that the front and rear strikers 24 can be simultaneously unlocked by simply operating one operation lever 44. At the same time, the lock position can be obtained. In addition, about one sheet | seat, the latching recessed part 22a of the latching metal fixture 22 located in the front can also be set so that it may open toward the front.
[0025]
By engaging the front and rear locking fittings 22 (the locking recesses 22a thereof) with the front and rear locking pins 24 and 25, they are slid in the front-rear direction along the guide rails 54. In order to lock the sheets 12 and 13 at a desired position, a known appropriate mechanism may be used. For example, the projections and recesses are formed on the side surfaces of the guide rails 54 at predetermined pitches, and on the sheets 12 and 13, locking claws that are engaged and disengaged with the projections and depressions may be provided. Further, the sliders 61 and 62 are electrically driven by a motor, and the locking function of the motor can be used as a locking mechanism for the seats 12 and 13 at a desired position. Of course, the distance between the left and right of the locking bracket 22 in the seats 12 and 13 is set to correspond to the distance between the pair of left and right guide rails 54.
[0026]
In order to achieve a double fault, it is only necessary to release the engagement with the rear locking pin 25 and perform forward rotation about the front locking pin 24. Double when the second row sheet 12 is moved forward on the front slider 61 with the front locking pin 24 as the center, and the third row sheet 13 is moved forward on the rear slider 62 with the front locking pin 24 as the center. The fault state is the state shown in FIG.
[0027]
After removing the third row sheet 13 from the rear slider 62 and engaging the front locking bracket 22 at the front portion of the third row sheet 13 with the rear locking pin 25 of the front slider 61, FIG. 4 shows a state when the third row sheet 13 is moved forward with the pin 25 as a center and double-faulted. At this time, the front-rear direction spacing of the front and rear locking pins 24 and 25 in the front slider 61 is double so that the double-faulted third row sheet 13 does not interfere with the double-faulted second row sheet 12. The thickness is set so as to be larger than the thickness in the front-rear direction of the third row sheet 13 when it is faulted.
[0028]
Here, as shown in FIG. 4, a holding stay 63 as a fixing means is provided on the lower surface of the seat cushion 13 </ b> A of the third row seat 13 so that the third row seat 13 double-faulted is not rearward. It is possible to prevent the situation of moving to the ready. Thereby, it is controlled that the 2nd row sheet 12 also moves back carelessly. Regardless of the rearward movement of the second row sheet 12 and the third row sheet 13 can also be performed by restricting only the second row sheet 12 by a fixing means. An appropriate method is adopted as the fixing means, such as fixing the second row seat 12 or the third row seat 13 so as not to move to the vehicle body side using a band (string) as the fixing means. obtain.
[0029]
Although the embodiment has been described above, the present invention is not limited to this, and includes the following cases, for example. The two sheets 12 and 13 may be double-faulted on the rear slider 62 (when securing a long luggage compartment in the front-rear direction immediately after the first row sheet 11). In this case, the second row sheet 12 may be removed from the front slider 61 and engaged with the front locking pin of the rear slider 62 (the sheets 12 and 13 in the state of FIG. The state that was moved to.) The purpose of the present invention is not limited to what is explicitly stated, but also implicitly includes providing what is substantially preferred or described as an advantage.
