Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a mattress, particularly a multilayer mattress.

[Conventional technology]

This type of mattress is commonly known as being placed between a pine tress and a sheet.

[Problem that this invention attempts to solve]

The object of the present invention is to provide a multilayer mattress that has an orthopedic function and, in particular, aids in the proper rest of the back and legs of the sleeper.

[Means to solve the problem]

In order to solve the above-mentioned problem, the present invention has been developed so that the transverse quilting seams extending transversely to the longitudinal direction of the mattress are narrower in the head and waist regions than the transverse quilting seams in the shoulder and leg regions. It is characterized by having.

[Effect of the invention] This cross-quilting seam prevents the various layers of stuffing from shifting and clumping together.
Furthermore, the mattress is divided into sections with different elasticity and filling volume.

〔Example〕

Next, one embodiment of the present invention will be described using the accompanying drawings.

In FIG. 1, the entire mattress is indicated by 1, 2 is the head area, 3 is the shoulder area, 4 is the waist area, and 5 is the leg area. Dividing the mattress 1 into respective areas 2-5 are transverse quilting seams 6.

FIG. 2 shows a part of the mattress according to FIG. 1, and the layers that make up the mattress can be clearly seen. In the middle of the mattress there is, as the main element, a core 7 made of foam material and having a protrusion 8 on the top. These protrusions 8 create a kind of pine surge effect on the sleeper and allow ventilation between the protrusions, thereby improving the ventilation of the mattress 1. A covering cloth 9 is provided above the core 7 made of a foam material,
A core 7 made of a foam material and a cotton filling 10 are separated. In this way, the cotton stuffing 10 is prevented from getting between the protrusions 8 and interfering with ventilation. The cotton padding 10 helps the sleeping person's skin breathe.

Synthetic wool 11 is below the core 7 made of foam material.
, which increases the cushioning effect of the mattress. Each type of mattress 1 has a common cotton cover 12.

The thickness and firmness of the mattress 1 differs in each region 2 to 5 depending on the arrangement of the transverse quilting seams 6. That is, in the head region 2, the intervals between the transverse quilting seams 6 are narrower, so
For example, compared to the waist region 4, in which the interval between the transverse quilting seams 6 is set larger than that of the head region 2, there are fewer irregularities and less elasticity. On the other hand, since there are no transverse quilting seams in the shoulder area 3 and leg area 5, the elasticity of the mattress 1 in these areas is large, and especially in the leg area 5, it is better for each layer of the mattress 1 to have high elasticity. Calf.

In this way, a relatively smooth and firm rug is provided for the pillow in the head area 2. In contrast, the shoulder area 3 is softer due to the absence of transverse quilting seams 6. There are transverse quilting seams 6 in the waist region 4, but they are more spaced apart than in the head region 2, so the cushioning is medium. In the leg region 5, since there is no transverse quilting seam 6, the mattress is sufficiently inflated, and the height of the sleeper's legs is set so as to help proper lying down and facilitate blood circulation. Such suitable leg height is also related to the placement of the transverse quilting seams 6 in the head region 2 and waist region 4. The mattress 1 has a longitudinally extending longitudinal quilting seam 14 which, as an aid to the transverse quilting seam 6, prevents the layers within the mattress 1 from shifting and deforming.

Next, embodiments of the present invention will be listed.

(1) Horizontal quilting seam 6
The mattress according to claim 1, wherein the spacing is narrower in the head region 2 than in the waist region 4.

(2) The mattress according to claim 1 or the above-mentioned item 1, characterized in that a transverse quilting seam 6 extending laterally only in the head region 2 and waist region 4 is provided.

(3) Claim 1, characterized in that vertical quilting seams 14 extending in the longitudinal direction are provided at intervals from both longitudinal edges of the futon 1, and the above-mentioned clause 1 or 2. The mattress mentioned.

(4) A core 7 made of a foam material with a protrusion 8 formed on one surface, and an upholstery 9 provided on the core 7,
The various layers of the mattress 1 have a common cotton cover 12, with a cotton padding 10 provided on the upholstery and a synthetic wool 11 provided below the foam material 7. The mattress according to claim 1 or any one of claims 1 to 3 above, characterized by:

Claims (1)

[Scope of utility model registration request] It is characterized in that the transverse quilting seams 6 extending transversely to the longitudinal direction of the mattress have a narrower spacing in the head region 2 and waist region 4 than the transverse quilting seams in the shoulder region 3 and leg region 5.
