Description

Structure for coupling a hinge and a knuckle of a second seat for RV vehicle}

The present invention relates to a coupling structure of a hinge and a nucleus in a center of a two-row seat of a recreational vehicle, and more particularly, in the case of a 6: 4 seat, which is a two-row seat structure of a recreational vehicle, The hinge structure of the two-row seat of the recreational vehicle which can improve the economics and productivity of the vehicle by reducing the parts and processes to be assembled is related to the combined structure.

In recent years, vehicles have become widespread, and the demand for leisure vehicles has also increased steadily. Unlike ordinary cars, recreational vehicles are arranged in a first-row seat with a driver and a passenger seat and two-row and three-row seats, which are multi-purpose seats for passengers to ride and load. The two-row and three-row seats of the recreational vehicle have a folding function to fold and unfold the seats of the vehicle, and the two-row and three-row rows of seats are freely arranged so that they can be changed for various purposes.

In addition, unlike the 5: 5 seat structure of a general passenger vehicle, a two-row seat of a recreational vehicle adopts a 6: 4 seat structure. The 5: 5 seat structure of a car is an even arrangement of the left and right seats, and the 6: 4 seat structure is divided into 6 and 4 ratios of left and right seats. A place is a seat structure arranged so that one person can ride. Thus, the folding of most recreational vehicles is also a 6: 4 arrangement.

On the other hand, such a combination of two rows of 6: 4 seats of the recreational vehicle is conventionally shown in the first, the second row of seats 10 of the recreational vehicle corresponds to the backrest of the two seats and the first backrest ( 20); A first knuckle arm 30 for adjusting the number of stages of folding; A second backrest 40 corresponding to the backrest of one seat; A second knuckle 50 for adjusting the number of stages of folding; A hinge plate 60 that interlocks and supports the first and second knuckles 30 and 50 when adjusting the number of folding stages; A connection bracket 70 connecting the first nucleus 30 and the hinge plate 60; A cushion support frame 80 connected to the connection bracket 70 to support the seat; And a seat frame 90 coupled to the vehicle body and finally supporting various loads of the seat, wherein the middle of the 6: 4 seat has a side surface of the first backrest 20. And the lower part is coupled to the connecting bracket 70 and the connecting bracket is coupled to the hinge bracket 60 at the same time. The hinge bracket 60 is coupled to the second backrest 40. In addition, the connecting bracket 70 is connected to the cushion support frame 80 at the bottom, and the cushion support frame is connected to the seat frame 90 and supported. The first knuckle 30 and the hinge of the middle portion of the 6: 4 seat are supported. A cross-sectional view of the coupling of the plate 60 and the connecting bracket 70 and the cushion support frame 80 is shown in detail in FIG. 2. As shown, the first knuckle 30 and the hinge plate are internally inward by the U-shaped connecting bracket 80 and fastened with bolts 31, and the connecting bracket 80 is cushioned frame downward. It is fastened with the bolt 31 perpendicular to the 80.

The order of this fastening process is to place the connecting bracket 70 on the cushion support frame 80 and fasten with bolts 31. After the first knuckle 30 is fastened with the bolts 31, the first backrest 20 is folded, and then the hinge plate 60 is fastened with the bolts 31.

However, in the two-row seat coupling structure 10 of such a conventional recreational vehicle, due to the shape of the connection bracket 70, there was a complexity of the process of carrying out work while folding and unfolding the seat at the time of fastening, and also consumed. The bolts are also consumed a lot, due to the increase in unit cost and weight, the workability during the tightening operation is lowered, the productivity is lowered, thereby lowering the economy.

The present invention is to solve the above disadvantages, to reduce the bolts consumed by removing the connection bracket, improve the ease of fastening work, the hinge of the two-row seat of the leisure vehicle that can increase the productivity and economics The purpose is to provide a combined structure of and knuckles.

-Explanation of symbols for the main parts of the drawing-

30, 110: Knuckle 31: Bolt

60, 120: hinge 70: connecting bracket

80: cushion support frame

In order to achieve the above object, the hinge structure of the two-row seat of the leisure vehicle provided by the present invention provides a coupling structure

A first backrest for two back seats;

2nd backrest for backrest of 1 seat;

A cushion support frame for supporting the load in the middle of the seat;

A first nucleus coupled to the side of the first backrest; And

The lower portion includes a hinge plate coupled to the cushion support frame and the upper side coupled to the second backrest.

Also preferably, the coupling may be bolted to the first knuckle and the hinge plate, the hinge plate may be welded to the cushion support frame.

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

3 is a perspective view of the center hinge connection of the two-row seat of the recreational vehicle according to an embodiment of the present invention, the central hinge connection 100 of the two-row seat of the recreational vehicle is the first backrest for two persons Backrest 20;

A second backrest 40 for backrest of a one-person seat;

A cushion support frame 80 for supporting a load in the middle of the seat;

A first nucleus 110 coupled to the side of the first backrest 20; And

The lower part includes a hinge plate 120 welded to the cushion support frame 80 and the upper side is connected to the second backrest 40, and the first nucleus 110 and the hinge plate 120 are bolted (not shown). ), The hinge plate 120 is coupled to the cushion support frame (80).

4 shows a detailed cross-sectional view of the first nucleus 110, the hinge plate 120, and the cushion support frame 80. As shown, the end portion of the first knuckle 110 in the detailed cross-section 200 is bent in a L-shape and is provided in step (S) shape stepped. The opposite side is provided with a hinge plate 120, the end of which is formed to be stepped in an L shape.

The first knuckle 110 and the hinge plate 120 are each closely contacted with each other and are coupled by the bolt 31. In addition, the combined hinge plate 120 is attached to the cushion support frame 80 and the attachment surface is welded 130 is coupled to the process.

The sequence of the above assembly process is as follows. First, the hinge plate 120 is attached to the upper portion of the cushion support frame 80 and then welded. The first knuckle 110 is then fastened with a bolt 31 penetrating the hinge plate 120. Therefore, preferably, the total process can be composed of two processes.

As described above, the coupling structure of the hinge and the knuckle of the two-row seat of the recreational vehicle according to the present invention directly removes the connecting bracket and fastens the first knuckle 110 and the hinge plate 120 directly with bolts 31. In addition, the number of bolts for fastening the cushioning frame to the hinge plate 120 to which the first knuckle 110 is coupled is reduced, thereby greatly shortening the process of joining parts and components, thereby improving productivity and economy of the vehicle.

Accordingly, the present invention is a leisure that can improve the economics and productivity of the vehicle by greatly reducing the parts and processes for assembling the left and right seat backrests in the combination of the hinge and the neck of the two-row seat of the recreational vehicle. It provides a combination of hinges and knuckles in a two-row seat of a vehicle.
