Abstract

The conventional heavy duty driver's seat frame of an automobile or an excavator has a structure in which an operating lever (tilting lever) is rotatably mounted on the side of the frame so as to press the upper portion of the holder bracket on the principle of a simple lever to release the ruler. The operating lever consists of two seats for front adjustment and rear adjustment, which makes it inconvenient to use and in the case of a narrow body space such as a small passenger car or an excavator, the operating lever is in close contact with the car body, The present invention for solving the problem that was difficult to operate is provided with a single operation lever to devise a way to easily and easily manipulate the seat tilting and seat height with this operating lever.

Description

Car Driver Position Control

The present invention relates to the structure of the seat lower frame structure of the driver's seat of an automobile or a heavy equipment. The structure of the frame fixedly mounted on the vehicle body to support the seat is conventionally composed of an upper frame and a lower frame in which the seat is fixed. The height adjustment and tilting device is connected to the holder bracket mounted on the side of the upper frame integrally with the lever to enable the rotation operation.

That is, the two left and right operating levers are fixed to the side of the upper frame, and by using the principle of the lever to press the upper portion of the holder bracket to release the locking device.

As described above, the conventional frame is equipped with two operating levers on the left and right, respectively, so that the structure is complicated, the manufacturing cost is high, and the driver's seat of the small passenger car or the heavy-duty vehicle, which has a narrow interior, is very narrow so that the operating lever located in the lower part of the seat can be used. Not only was it inconvenient, but also the backrest was tilted and there was no device for adjusting the height of the seat.

The present invention as described above based on the accompanying drawings as a configuration to devise the tilting of the seat and the height of the seat as one operation lever to eliminate the inconvenience as described above.

In the left and right of the position where the operating lever 2 of the quadrilateral lower frame 1 fixed to the vehicle driver's seat body is installed symmetrically between the locking section 3 and 3a. 4a) is coupled to the hinge (6) (6a) to be freely rotated to the left and right ends of the main wall (5) of the pair of lower frame (1). And the lower side of the "c" type operation | movement operation | movement 7 (7a) inside the board | substrate 4 (4a) couple | bonded with this hinge 6 (6a) also hinged like the board | substrate 4 (4a). (6) (6a), and the upper frame 10, which is slightly larger than the lower frame 1, is coupled to the freely rotatable upper part of the lower frame 1, and the inner bulkhead 11 of the upper frame 10 is positioned. (11a) Four connecting rods 12, 12a (two remaining not shown) are symmetrically connected to the hinge 6j at the left and right ends, and the connecting rod 12 on the side where the operating lever 2 is located. (12a) The engaging pieces 3b and 3c located on the upper side of the engaging pieces 3b and 3c protrude outwardly, and the engaging pieces 3b and 3c are formed through holes formed at both ends of the inner partition wall 11. It penetrates (13) and protrudes outward.

Then, two long holes 14 and 14a of a predetermined length are cut in the inner partition wall 11 in the longitudinal direction of the inner partition wall 11, and a plurality of planar ratchets 15 are formed on the upper surfaces of the long holes 14 and 14a, respectively. The holder brackets 16 and 16a, which are 15b) protruding from the top edge and the inner bulkhead 11 and the hinges 6b and 6c, are installed, and the holder brackets 16 and 16a are hinged approximately at the middle part. 6e) is freely engaged with the intermediate upper surface of the actuating lever 2 and the projections 17 and 17a of the end portions bent upward.

In addition, a tension spring 18 is interposed between the holder bracket 16 and the holder bracket 16a, and as shown in FIG. 2, the inner side of the inner partition 11 is fixed in the longitudinal direction of the inner partition 11. A guide rail 19 having a width is formed to include two guides 20 and 20a which slide on the guide rail 19 so that this guide 20 (20a) is connected to the upper end of the span 4 and 4a. Engaging pieces (3) (3a) protruding from the through pieces, and engaging pieces (3) (3a) protruding through the guides (20) and (20a) and locking pieces (3b) protruding from the inner partition wall (11). The tension springs 18a and 18b are interposed between (3c).

And between the four projections 21, 21a (not shown) protruding from the four corners of the lower frame (1), the "c" type between the operation (7) (7a) to the speech between the operation (7) The lower edge portion of the 7a and the projections 21 and 21a are rotatably coupled to the hinges 6f and 6g, respectively, and the inner central portion and the lower frame 1 of the inner partitions 11 and 11a are rotated. Speak the support rods 22 and 22a so as to be freely rotatable between the protrusions 21 and 21a protruding from the upper side, and the upper side is joined by the hinges 6h and 6i and the lower side is the hinge 6f and 6g. To combine.

In addition, the entire configuration of the present invention is made by connecting the upper end and the front end of the four "c" type operation (7) (7a) (the other two are not shown) by the coupling rods (23) (23a).

Referring to Figure 3a attached to the operating state of the present invention configured as described above, Figure 3 is a front operating state diagram of the vehicle driver seat position adjustment device is implemented according to the present invention "A" figure is the upper seat frame 10 is horizontal A ratchet in which the engaging pieces 3, 3a protruding from the upper side of the interlocking sections 4, 4a interposed symmetrically on the left and right sides as raised state front views are cut in the holder brackets 16, 16a, respectively. (15) (15a) is engaged with the outermost ratchet and the operating lever 2 is in a horizontal state, and when the operating lever 2 is pushed downward, the operating lever (2) as the tip and the hinge (6e) The holder bracket 16 coupled with the hinge 6d protruding from the projection lever 17 protruding from the center of the actuating lever 2 centers on the hinge 6e extending from the holder bracket 16a and the hinge 6b. The locking piece 3 engaged with the ratchet 15 of the holder bracket 16 while being inclined downward is attached to the ratchet 15. At the same time, it is pushed out by the tension restoring force of the spring 18a that has been compressed, and pushes the catching piece 3 addressed to the tip of the spring 18a. (4) the hinge 6 coupled to the lower end is inclined downward with respect to the axis so that one side of the upper frame 10 is tilted as shown in FIG. On the contrary, when the actuating lever 2 is raised, this time is engaged with the ratchet 15a of the holder bracket 16a as opposed to Fig. 3b with the hinge 6d protruding from the actuating lever 2 in the middle of Fig. 3c. When the latching piece 3 at the tip of the railing section 4a that has been disengaged from the ratchet 15a is uniformly pressed against the driver's seat fixed to the upper surface of the upper frame 10 in this state, the upper frame 10 in FIG. 3d. This will descend horizontally.

On the contrary, when the upper frame 10 is raised, the operation lever 2 is pushed and then raised in the same manner as the lowering as described above. If the upper frame 10 is not loaded, the springs 18 and 18a are lifted. The restoring force of 18b causes the return to the initial state of FIG. 3a.

As described above, the operation lever on the side of the conventional seat is positioned forward from the side to raise and lower the upper frame 10 by one operation lever (2), so that a sufficient space is secured and the operation is easy and the structure is relatively simple. The operation is simple and clear, and the manufacturing cost is reduced.
