Lower pitch locked type seat locking device in vehicle

TECHNICAL FIELD The present invention relates to a seat locking device, and more particularly to a seat locking device of a low stage pitch lock type.

In general, the seat seated by the passenger is equipped with a locking device for fixing the adjustment state while being able to adjust while moving the seat in the forward and rearward directions as the physical condition of the passenger is different.

Such a locking device is typically provided with an upper rail mounted on a cushioning part on which a passenger is seated and moved forward and backward when the lock is released, and a bottom of the vehicle body to guide when the upper rail is moved forward and backward. A lower rail fixed to the floor panel is provided, and the upper rail is movable when the lock is released, and a locker assembly is coupled to the lower rail when locked.

In addition, a built-in rail is provided with an operating lever for operating the locker assembly when unlocking.

Accordingly, when the passenger operates the operation lever, the locker assembly releases the lock on the lower rail, and such unlocking between the lower rail and the locker assembly enables the upper rail to move forward and backward. The passenger will be able to adjust the upper seat rail mounted on the cushioning area along the lower rail to adjust the optimum seat clearance.

However, the locker assembly which enables the movement and fixation of the seat thus corresponds to the locking hole in which the locking plate for locking and releasing action is formed at equal intervals in the lower rail, that is, the pitch of the locking hole spacing of the lower rail. As the movement distance of the seat is completed only when the insertion stage formed at the bottom of the locking plate coincides with (Pitch), it is inconvenient to match the coupling position of the locking hole of the lower rail and the locking plate during the operation process. .

In addition, the locker assembly locking structure, which causes inconvenience in pitch matching during operation, does not have a margin for dimensional error between the locking plate and the lower rail, and in a deformation state caused by long time use. The tendency of incomplete locking may also increase during seat adjustment.

In view of the above, the present invention has been invented, and between the upper rail mounted on the seat cushion and the lower rail fastened to the floor of the vehicle, a locker assembly having a locking and releasing action is provided. As the locking plate is composed of a plurality of overlapping widths (lateral directions) between the lower and upper rails, the space occupied by the locker assembly positioned between the lower and upper rails is reduced as much as possible, It is an object of the present invention to provide a seat locking device capable of preventing a reduction in strength of the lower rail while minimizing the reduction of the bite cross-section of the lower rail by fitting a plurality of locking plates to the lower rail.

In addition, the seat locking device of the present invention is composed of a plurality of locking plates in which a locker assembly, which is fitted to the lower rail and forms a fixing force, overlaps in the width (lateral direction) between the lower and upper rails, As the pitches of the plurality of locking plates may be formed differently with respect to the pitches of the locking plates, some of the locking plates fitted to the lower rails during the locking action after the seat adjustment are selectively coupled to form a fixing force. In addition, some locking plates, which were not fitted to the lower rail when the seat is readjusted, are selectively engaged again, so that the pitch of the locking plate is always stable while the pitch of the locking rail spacing of the lower rail is short. The purpose is to keep it locked.

The present invention for achieving the above object, the seat locking device is mounted on the seat cushion and the upper rail which is moved forward and backward with the cushion;

A lower rail having a plurality of locking holes opened at equal intervals from each other to be processed so that the upper rails fitted in a state fixed to the floor of the vehicle body are moved forward and backward;

The upper part is positioned on the upper rail side and the lower part is joined to the lower rail side, so that the upper and lower rail widths (lateral direction) can be released and locked against the locking hole of the lower rail when the upper rail moves due to seat adjustment. A locker assembly composed of a plurality of locking plates that are overlapped with each other and overlap with each other at one side with a clearance gap;

A handle assembly embedded in the upper lower rail so that the locking plate can be lifted to move the seat adjustment to unlock the locker assembly to the lower rail and can be operated by hand;

. ≪ / RTI >

For this purpose, the locker assembly is composed of a plurality of first, two, three, and four locking plates that are alternately overlapped with each other with a shorter gap than a pitch, which is an interval between a plurality of locking holes of a lower rail,

The first, second, and third locking ends having the same spacing as the pitch interval between the locking holes are formed so as to be fitted into the locking holes of the lower rail as the lower end portions of the first, second, third, and fourth locking plates.

According to the present invention, as the locker assembly is inserted into the lower rail constituting the seat locking device to form a fixing force (locker assembly) consists of a plurality of locking plates overlapping in the width (lateral direction) between the lower upper rail, When assembling, the occupied space of the locker assembly is reduced to the maximum, and the reduction of the bite section of the lower rail can be minimized to prevent the overall decrease in strength, and the pitch of the multiple locking plates against the pitch of the lower rail Since the pitches may be formed differently, the pitch of the locking plate may be shortened with respect to the pitch, which is the interval between the locking holes of the lower rail, and the stable locking state may be maintained at all times.

The locker assembly 3 is formed of a plurality of first, two, three, and four locking plates 4, 5, 6, and 7 overlapping in the width (lateral direction) between the lower upper rails 2 and 1. In the seat adjustment, the locking of the lower rail 2 is performed after the adjustment of the first, second, third, and fourth locking plates 4, 5, 6, and 7 is completed. Selected to each other in the hole 2a (for example, the first and second locking plates 4 and 5, the second and third locking plates 5 and 6, or the third and fourth locking plates 6 and 7). As it is fitted, the pitch, which is the interval between the multiple locking holes 2a of the lower rail 2, is reduced to 1 / n (the pitch is reduced to 1/4 for four locking plates) by the number of locking plates. I can give it.

To this end, the first, second, third, and fourth locking plates 4, 5, 6, and 7 are arranged so that the first, second, third, and fourth locking plates 4, 5, 6, and 7 have overlapping clearance intervals c as shown in FIGS. On the basis of the locking plate 4, the second, third and fourth locking plates 5, 6, and 7 are superposedly overlapped at overlapping clearance intervals c, respectively.

Further, the first, second, third, and fourth locking plates 4, 5, 6, and 7 are formed in the lower part with a plurality of engaging ends that fit in the locking holes 2a of the lower rail 2 in the same shape. The locking stages include first and second locking stages 4a, 5a, 6a, 7a, 4b, 5b, 6b, 7b, 4c, 5c, and 6c having the same interval as the pitch interval between the locking holes 2a. And 7c), respectively.

That is, the first, second and third locking ends 4a, 5a, 6a, 7a, 4b, 5b, 6b, 7b, 4c, 5c, 6c, and 7c are the first locking ends 4a, 5a, 6a, and 7a. The second locking ends 4b, 5b, 6b, and 7b are formed at the same interval as the pitch interval between the locking holes 2a with respect to the second locking ends 4b, 5b, 6b, and 7b. The third locking ends 4c, 5c, 6c, and 7c are also formed at the same interval as the pitch interval between the locking holes 2a.

It has a locker guide that is assembled while receiving as a medium, the handle lever for holding and operating by hand inside the seat is provided with a spring providing elastic force, this handle assembly 10 structure is seat locking for seat adjustment It will have a conventional configuration applied to the device.

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

The seat locking device of the present invention is installed between upper and lower rails (1, 2) provided between the seat and the bottom of the vehicle body, respectively, and locker assembly for releasing the lock state by operating the handle assembly (10) during seat adjustment. (3), wherein the locker assembly (3) forms a plurality of locking ends that fit into the locking holes (2a) of the lower rail (2), and pitch intervals between the locking holes (2a) There is a feature consisting of a plurality of locking plates (4, 5, 6, 7) arranged in the width (lateral direction) of the lower rail (2) while being staggered with each other to have a overlapping clearance gap (c) which is a shorter interval. do.

With this feature, the occupancy length of the locker assembly 3 with respect to the upper lower rails 1 and 2 in the assembled state of the seat locking device is shortened, and the locking of the lower rail 2 after the seat adjustment operation is performed. Due to the overlap clearance gap c of the first, second, third, and fourth locking plates 4, 5, 6, and 7 that are selectively fitted to each other with respect to the pitch, which is the spacing of the holes 2a, the upper In the case of four locking plates, the moving distance of the rail 1 is reduced to a pitch of 1/4 to reduce the cushion movement adjustment at shorter intervals, but also to form a stable locking state at all times.

To this end, the seat locking device of the present invention, as shown in Figure 1, is mounted between the upper rail (1) and the lower rail (2) fixed to the vehicle floor (Floor) is mounted on the seat cushion and moved forward and backward with the cushion A plurality of first, two, three, four lockings positioned and exiting to the locking holes 2a formed in the lower rail 2 while being moved through the handle assembly 10 which is held and operated by hand when adjusting the seat. It consists of a locker assembly 3 which consists of plates 4, 5, 6 and 7.

The locker assembly 3 is able to maintain a stable locking state while reducing the adjustment interval of the sheet shortly when adjusting the seat, which is the locker assembly 3 as shown in Figure 2 the lower rail (2) A plurality of first and second arrays arranged in the width (lateral direction) of the lower rail 2 while overlapping at overlapping clearance intervals c at intervals shorter than the pitch Pitch, which is an interval between the plurality of locking holes 2a, respectively. 3 and 4 locking plates 4, 5, 6 and 7.

Due to this, the adjustment movement distance of the seat may be shorter when the seat is adjusted, that is, the first and second locking plates 4 and 5 in the locking hole 2a of the lower rail 2 as shown in FIG. When the handle assembly 10 is manipulated to readjust the seat in the state of being fitted and fixed, the locker assembly 3 locks the locking hole 2a of the lower rail 2 as shown in FIG. The upper rail 1 is pushed out by the force exerted by the force on the seat.

As described above, the first, second, third, and fourth locking plates 4, 5, 6, and 7 of the rocker assembly 3 detached from the lower rail 2 are moved relative to the lower rail 2, Due to this positional movement, as shown in Figs. 3 (b) and (c), the first, second, third, and fourth locking plates (4, 5, 6) fitted into the locking holes (2a) of the lower rail (2). , 7 becomes different, i.e., if the first and second locking plates 4 and 5 are fitted into the locking holes 2a of the lower rail 2 before the movement, the locking holes 2a of the lower rail 2 after the movement. ), The second and third locking plates 5 and 6 are fitted, and when the cushion is adjusted again, the third and fourth locking plates 6 and 7 are fitted.

The selective coupling action of the locking plates 4, 5, 6, and 7 is based on the pitch between the locking holes 2a of the lower rail 2, which has a preset length. (7) is reduced, i.e., overlapping with overlapping clearances (c) at intervals shorter than the pitch (Pitch) between the locking holes (2a), for example, lower in the locked state after the seat adjustment Compared to the first and second locking plates 4 and 5 fitted into the locking hole 2a of the rail 2, the third and fourth locking plates 6 and 7 are located at the flesh portion between the locking holes 2a. Because it has.

The above-described operation between the first, second, third, and fourth locking plates 4, 5, 6, and the lower rail 2 will be described in detail. In the case where one locking plate 4 is used, the lower rail will be described. 4 (a) to (c) as the pitch (P) which is the interval (b) between the locking holes 2a of (2) and the pitch (P) which is the interval (a) of the locking plate 4 coincide with each other. As shown in FIG. 2, the moving distance of the locking plate 4 when the seat is moved is limited to a pitch, which is a distance b between the locking holes 2a of the lower rail 2, which is a movement for adjusting the seat. There is a limit that can only be increased in the interval between the locking holes (2a) of the rail (2).

However, when the two first and second locking plates 4 and 5 are used as shown in FIGS. 5 (a) and 5 (c), the interval a, pitch 'a') coincides with the pitch P which is the interval b between the locking holes 2a of the lower rail 2, but the first and second locking plates 4 and 5 are shifted from each other. By overlapping to form the overlap clearance gap c, the first, second and third locking ends 4a, 4b and 4c of the first locking plate 4 are fitted into the locking holes 2a of the lower rail 2. On the other hand, the first, second, and third locking ends 5a, 5b, and 5c of the second locking plate 5 are maintained at positions of the flesh between the locking holes 2a of the lower rail 2.

As such, the mismatch between the first and second locking plates 4 and 5 is such that when the sheet moves, the first and second locking ends 5a, 5b and 5c of the second locking plate 5 are located in the lower rail 2. It means that only the gap that can be fitted to the locking hole 2a of the movement, i.e., overlaps the clearance gap c, is shorter than the pitch formed between the locking holes 2a of the lower rail 2. It can be seen that the first and second locking plates 4 and 5 overlap with the clearance gap c.

Since the overlap clearance gap c of the plurality of overlapping locking plates depends on the number of overlaps of the locking plates, the lower rail in the case of the first, second, third, and fourth locking plates 4, 5, 6, and 7 The overlapping clearance gap c is formed to have a quarter interval shorter than the pitch formed between the locking holes 2a of (2), so that the locking hole 2a of the lower rail 2 during sheet adjustment is provided. The pitch can be adjusted while moving a short distance at a quarter interval compared to the pitch formed.

In this way, when the front and rear gap adjustment of the seat is completed and the handle assembly 10 is returned to its original position, the first and second locking plates 4 and 5 that are fitted into the locking holes 2a of the lower rail 2 are pulled out. At the same time, the second and third locking plates 5 and 6 are switched to the fitted state to maintain the fixing force. Then, in the next adjustment step, the second and third locking plates 5 and 6 are pulled out and the third and third locking plates 5 and 6 are removed. The four locking plates 6 and 7 are switched to the fitted state so that the upper rail 1 and the lower rail 2 can be fixed to each other.
