Description

[Detailed Description of the Invention] The present invention relates to an improvement of a lumbar support consisting of a plurality of air bladders attached to an automobile seat, etc., in which a seat spring stretched on a seatback frame is The purpose of this product is to provide a lumbar support that is easy to assemble and can function satisfactorily when the body pressure of a seated person is applied, regardless of whether the seat back is stretched in the height or width direction. There is.

A lumbar support with a structure in which multiple air bladders that are selectively inflated are hung horizontally in parallel is already known, but this one has a lumbar support in front of a seat spring stretched in the height direction of the seat back. Since the air bag is arranged and received perpendicularly, and the seat pad is placed on the front side of the air bag, the seat spring is attached to the seat bag that is stretched in the width direction of the seat bag, that is, in the lateral direction. When applied, when the body pressure of a seated person acts on the lumbar support, the air bladder tends to roll between the seat springs stretched in the lateral direction, resulting in the disadvantage that sufficient lumbar support function cannot be achieved. have.

The present invention provides a lumbar support that does not have the above-mentioned drawbacks and is easy to assemble by adopting the configuration described in the claims of the utility model registration.

The configuration of the illustrated example will be described below.

The lumbar support 1 according to the present invention is shown in FIG.
As shown in FIG. 6, it is arranged on the front side of the seat pad 3 of the seat bag 2.

The seat bag 2, as shown in FIG.
In order to achieve a design effect, a concave portion, usually called a suspension 4, is formed in the skin material 5, and as shown in FIG. A seat pad 3 having a structure as shown in FIG. 4 is fitted onto a stretched barrel seat spring 7, and a seat pad 3 is formed in advance at the position where the suspension 4 is formed by penetrating the front and back sides of the seat pad 3. It is formed by utilizing the opening 8 and pulling and fixing the skin material 5 toward the seat spring 7 using a fastener.

The lumbar support 4 according to the present invention is assembled using the seat pad 3 that can form the suspension 4 as described above.

That is, as shown in FIG. 5, extending shoulder pieces 13 and 14 are formed on both upper edge shoulders of the base sheet 12 on which a plurality of air bags 9, 10, and 11 are horizontally suspended in parallel. Mounting holes 15 and 16 are formed in the base sheet 12, and the base sheet 12 is placed on the front side of the seat pad 3 shown in FIG.
3 and 14 are pulled out to the seat spring 7 side from the opening 8 for forming the suspension 4 of the seat pad 3.

Then, as shown in FIG. 6, the skin material 5 is pulled with a hanging cotton cloth 17 through the opening 8 of the seat pad 3 toward the seat spring 7, and the hanging cotton cloth 17 is attached to the seat spring with a fastener 18 called a so-called hog ring. 7, the fasteners 18 are also engaged with the mounting holes 15 and 16 of the extending shoulder pieces 13 and 14, and both the skin material 5 and the base sheet 12 are fixed to the seat spring 7 side. This completes the assembly of the lumbar support 1.

As shown in FIGS. 7 and 8, in a seat bag having a structure in which the suspensions 19 and 20 corresponding to the suspension 4 are formed using buttons 21 and 22, the buttons 21 and 22 are attached to the seat springs using fasteners 23. 2
4 is attached to the base sheet 27 of the lumbar support 26.
This is an example in which the base sheet 27 is fixed to the seat spring 24 along with the skin material 30 and the button 22 by inserting it into the mounting hole 29 of the shoulder extension 28, and the lumbar support 26 is arranged on the front side of the seat pad 31. The structure is the same as that shown in FIGS. 1 and 6 above.

In each of the embodiments described above, the seat spring 7
Alternatively, the seat spring 24 is stretched in the width direction of the seat bag, but it goes without saying that the seat spring may be stretched in the height direction of the seat bag. In FIG. 1, reference numeral 32 is a manual pump, and reference numeral 33 is an air bag 9, 10, 1 into which air is to be pressurized.
1 selection and switching button device.

The present invention has the above-mentioned configuration, and since the lumbar support is located directly under the skin material on the front side of the seat pad and is received by the thick seat pad, it is completely unrelated to the orientation of the seat spring, and the lumbar support No matter which direction the body pressure is applied, sufficient lumbar support function can be exerted without causing rolling or the like, and since the body pressure is applied at a position close to the body, the texture is sharp.

In addition, in order to create a design effect, the base sheet of the lumbar support is fixed to the seat spring side together with the skin material using the fasteners that fix the skin material to the seat spring, so the seat back of the conventional seat is fixed. It also has the advantage that it can be easily assembled without requiring any structural changes.
