Abstract

The utility model discloses a novel seat back cushion which is composed of a base body and a top layer in a folding manner, wherein a transparent section is arranged at the middle part of the base body; the novel seat back cushion can adapt to the physiological features of a human body with bent back spine by the transparent section; concentrated oppression on the spinal column is reduced; and the back cushion can evenly bear the back of a user. Therefore, the use comfort is improved.

Description

A kind of Novel seat backrest pad

Technical field

The utility model is about a kind of seat, and is special relevant with the back cushion of seat.

Background technology

Backrest plays the effect at support human body back, be lined with soft pad on the backrest of some seats to improve comfort level, usually pad is to adopt high-density sponge or other soft material one monoblock to make, this back cushion relatively is fit to the normal people in back and uses, but for personage bow-backed, spinal curvature, because backbone is crooked, therefore general back cushion can't be carried whole back uniformly, spinal curvature, bossing bear larger compressing, take for a long time and feel uncomfortable, this case namely improves for this deficiency.

The utility model content

The utility model provides a kind of Novel seat backrest pad, can adapt to human body back spinal curvature person's physiological characteristic, improves the comfortableness of using.

For achieving the above object, solution of the present utility model is: a kind of Novel seat backrest pad, to being combined into, the middle part of this matrix is provided with hollow part to this back cushion by matrix and top layer.

The both sides of this matrix stretch out and form two catch, and this top layer is provided with the bend that cooperates with matrix two catch.

This matrix adopting hardness is HW80 degree～HW100 degree, and density is 80～100Kg/m ³Sponge make.

It is HW40 degree～HW60 degree that this top layer adopts hardness, and density is 20～30Kg/m ³Sponge.

Further, this back cushion also is provided with both sides back-up block and a lumbar support piece between matrix and top layer.

This both sides back-up block symmetry is bonded in the both sides of matrix hollow part.

It is HW60 degree～HW80 degree that this both sides back-up block adopts hardness, and density is 40～60Kg/m ³Sponge.

This lumbar support piece is bonded in the below of matrix hollow part.

It is HW50 degree～HW70 degree that this lumbar support piece adopts hardness, and density is 30～50Kg/m ³Sponge.

It mainly is to utilize the hollow part of matrix can adapt to human body back spinal curvature person's physiological characteristic that the utility model back cushion adopts said structure, reduces the concentrated compressing to backbone, makes back cushion can carry uniformly user's back, improves comfort.

The specific embodiment

Below in conjunction with accompanying drawing and implementation the utility model is explained.

As shown in Figures 1 to 4, be a kind of Novel seat backrest pad of the present utility model, this back cushion is to form by the sponge of some different hardness and density is bonding, specifically comprise a matrix 1, both sides back-up block 2, a lumbar support piece 3 and a top layer 4, matrix 1 is involutory with top layer 4 front and back, and both sides back-up block 2 and lumbar support piece 3 are located between matrix 1 and the top layer 4;

Wherein, this matrix 1 has the effect of certain support as bottom, and adopting hardness is HW80 degree～HW100 degree, and density is 80～100Kg/m ³Sponge, the middle part of matrix 1 is provided with hollow part 11, the position of these hollow part 11 corresponding human body back backbones, the both sides of matrix 1 stretch out and form two catch 12 again, the side locations of these two catch, 12 corresponding person plays certain supporting role;

These both sides back-up block 2 symmetries are bonded in the both sides of matrix hollow part 11, and the position, both sides of its corresponding human spine is that employing hardness is HW60 degree～HW80 degree, and density is 40～60Kg/m ³Sponge;

This lumbar support piece 3 is bonded in the below of matrix hollow part 11, the position of its corresponding human body waist, and adopting hardness is HW50 degree～HW70 degree, density is 30～50Kg/m ³Sponge;

This top layer 4 is as outermost layer, and integral coating is on matrix 1, both sides back-up block 2 and lumbar support piece 3, and adopting hardness is HW40 degree～HW60 degree, and density is 20～30Kg/m ³Sponge, the most soft, for and the human body soft contact, this top layer 4 is provided with the bend 41 that matches with matrix two catch 12 again.

The utility model back cushion adopts said structure can reach following beneficial functional:

1, mainly utilizes the hollow part of matrix can adapt to human body back spinal curvature person's physiological characteristic, reduce the compressing to backbone;

2, provide preferably support by both sides back-up block and lumbar support piece to human spine both sides and waist position;

3, by the catch of matrix both sides, can play to the sidepiece of human body the effect of support when laterally inclined at health.

The above, it only is the utility model preferred embodiment, when not limiting the scope that the utility model is implemented with this, any equivalence of doing according to the utility model claims and description changes and modifies, and all should belong in the scope that the utility model patent contains.
