Abstract

The utility model relates to a chair back structure capable of twist deformation. The chair back structure is characterized in that a plurality of penetration holes are formed on a chair back made of compound plastic material; each penetration hole takes the shape that the diameter of the middle is larger than the diameters of the two ends; each penetration hole and adjacent penetration holes on the sides are arranged in a staggered manner; the chair back is arc-shaped and raised from two sides to the center and in the direction from the front side of the chair back to the back side; and the part from the center of the chair back to lower section part of the bottom and in the direction from the back side of the chair back to the front side are arc-shaped and raised to form a waist rest part. The chair back structure capable of twist deformation can fit the curve of the back of a human body leaning back, conforms to ergonomics and achieves the effect of more comfortableness in sitting and leaning.

Description

But the back structure of torsional deformation

[technical field]

But the utility model relates to a kind of back structure of torsional deformation, and especially a kind of have soft to be back curve when meeting that human body reclines, to be to take the back structure innovative design that reclines more comfortable.

[background technology]

Chair tool on the market can be provided with the chair back in the cushion rear end of Gong taking usually for the comfortableness when taking is provided, and makes the occupant when taking during this chair tool; Can its back be posted by this chair back; Make the back under the support of the chair back, alleviate human vertebra and bear human weight, and more comfortable person.

The material that the chair back of general plastic cement system is selected for use usually is all comparatively hard, and leans on portion for being wholely set waist, so that can't produce docile effect with human body back, does not meet ergonomics, and can't reach the effect of effective support human body back; Moreover; The chair back of these plastic cement systems is because of considering structural strength; So any perforation is not set on the chair back of these plastic cement systems, thus when human body back when being posted by this chair back, be to be close-fitting state between human body back and this chair back; Do not possess ventilation effect, so occupant's back is not easy to feel sultry uncomfortable.

Therefore, if can provide a kind of has softness and supportive concurrently, and the chair back of air ventilation effect, can make the occupant more comfortable on taking, the present, Given this creator promptly is, so found out the utility model.

[utility model content]

But the main purpose of the utility model is to provide a kind of back structure of torsional deformation; This chair back has good supporting property and flexibility; Can be with the curve deformation of human body back, and and produce good docile state between human body back, and have good ventilating permeability effect.

The purpose of the utility model is achieved in that a kind of structure that leans against of chair tool; It is the chair back that adopts plastic cement composite integral production to form; A plurality of perforation are set on this chair back; Each perforation all is little and the shape that the aperture, two ends is big of median pore radius, and between adjacent each perforation of side for being crisscross arranged;

In the said structure, this chair back is convexly equipped with setting toward middle towards the positive direction arc that points to the back side of the chair back by both sides;

In the said structure, the direction arc that points to the front to the past chair back back side, the hypomere position of bottom in the middle of this chair back is convexly equipped with to form waist and leans on portion.

The beneficial effect of the utility model is: this chair back is because of being to adopt plastic cement to meet material; And itself has the little and perforation of the shape that the aperture, two ends is big of a plurality of median pore radius; Add between the perforation of adjacent each of side to being crisscross arranged, make this chair back have the effect of soft distortion and support, and the curve can further recline in response to human body back the time; With ergonomic, reach and take effect more comfortable when reclining, that ventilate.

But Fig. 2 is the left view of the back structure of the utility model torsional deformation

But Fig. 3 is the vertical view of the back structure of the utility model torsional deformation

Among the figure: 1, the chair back 2, first direction 3, second direction 4, waist lean on portion 11, perforation

[specific embodiment]

For the technological means that makes the utility model, create purpose and reach effect and have more complete and clearly disclose, now in specifying down, and please consult the diagram and the component symbol of announcement in the lump.

See also Fig. 1 to Fig. 3, it is respectively front view and left view, the vertical view of the back structure of the utility model.The chair back 1 of the utility model forms to have flexible for adopting plastic cement composite integral production; This chair back 1 itself is convexly equipped with setting toward middle towards first direction 2 (the positive direction of pointing to the back side of the chair back) arc by both sides; Following section side to low side in the middle of this chair back 1 is convexly equipped with setting toward these first direction 2 opposite second direction 3 (positive direction is pointed at the chair back back side) arcs, and forms waist according to this by portion 4; A plurality of perforation 11 are set on this chair back 1, and each perforation 11 all is little and the shape that the aperture, two ends is big of median pore radius, and 11 of adjacent each perforation of side are for being crisscross arranged.

When the plate face that when recline with the human body back chair back 1 and the chair back 1 is bore and lies by power, the material of itself selecting for use by the chair back 1 had flexible, and the set little and big shape in aperture, two ends of median pore radius that is on the collocation chair back 1; And adopt the adjacent a plurality of perforation 11 that are crisscross arranged of side, make this chair back 1 have can elastic bending effect, and with human body back curve and applying; Provide lie by the time elasticity comfortableness; Especially the chair back 1 is provided with at corresponding human body waist place toward the waist of second direction 3 protrusion and leans on portion 4, can push up and paste the human body waist, makes when taking human body waist acquisition support and feels comfortably cool; More increase the characteristic of this chair back 1 ergonomic; Even the perforation 11 that sees through the chair back 1 is provided with, further provide lie by the time gas permeability, unlikelyly feel sultry.

The preferred embodiment that is merely the utility model described above, above-mentioned specific embodiment are not the restrictions to the utility model.In the technological thought category of the utility model, various distortion and modification can appear, and the retouching that all those of ordinary skill in the art make according to above description, revise or be equal to replacement, all belong to the scope that the utility model is protected.

Claims

1. but the back structure of a torsional deformation; It is characterized in that: it is the chair back that adopts plastic cement composite integral production to form; A plurality of perforation are set on this chair back, and each perforation all is little and the shape that the aperture, two ends is big of median pore radius, and between adjacent each perforation of side for being crisscross arranged.
