Abstract

The utility model relates to a headrest or waist-rest framework structure for a chair. The headrest or waist-rest framework structure is provided with a backrest base plate and is characterized in that a tongue-shaped structure with certain elasticity is transversely arranged at a headrest position or/and a waist-rest position; the tongue-shaped structure is a U-shaped section with two asynchronous edges; and the short edge of the U-shaped section is connected with the backrest base plate and the long edge of the U-shaped section is suspended. The tongue-shaped structure has certain elasticity; therefore, when the framework is coated with a soft cushion, the appearance and the shape of the chair are enriched; the elasticity of important positions of the chair, such as the headrest and the waist-rest, is improved, so that people feel comfortable; moreover, the headrest or waist-rest framework structure for the chair has an attractive appearance and a simple structure.

Description

Seat headrest or waist lean on skeleton structure

Technical field

The utility model relates to a kind of furniture, relates in particular to the skeleton structure of a kind of head-rest or back of the body pad.

Background technology

It is tired that traditional office seating very easily makes labourer's muscle produce static(al), and produce malaise symptoms such as the small of the back ache, not only influenced operating efficiency, and labourer's body and mind has been caused certain injury.Along with the raising of living standards of the people, people are also increasingly high to the requirement of the comfortableness of thing to sit on and aspect such as attractive in appearance.Be meeting the market requirement, therefore, develop a kind of office chair comfortable, simple in structure, good looking appearance that is seated, become furniture design personnel's maximum wish.

Summary of the invention

The utility model main purpose is: lean on skeleton structure for furniture market provides a kind of be seated seat headrest or waist comfortable, simple in structure, good looking appearance.

The above-mentioned technical problem of the utility model mainly is able to solve through following technical proposals: a kind of seat headrest or waist lean on skeleton structure; Has the backrest substrate; It is characterized in that: the headrest of said backrest substrate or waist lean on or headrest leans on the position setting to have certain flexible tongue structure with waist, and said tongue structure is asymmetric U-shaped cross sections, both sides, and its minor face is connected with said backrest substrate; Long limit is unsettled, makes it to produce certain elasticity.

The technical scheme of the utility model can also be further perfect:

As preferably, said tongue structure is a lateral arrangement.

As preferably, said tongue structure is provided with waling.

Another preferred version is: the width of tongue structure adapts to the radian of backrest substrate.Simultaneously, on the width of tongue structure longitudinal groove is arranged, make whole tongue structure have better elasticity.

As preferably, its short brink of said U-shaped cross section is provided with outside bending, to increase the elasticity of tongue structure.

As preferably, the material of said tongue structure adopts the rubber-like engineering plastics.

The beneficial effect of the utility model is:

Because be provided with asymmetric U-shaped cross section, both sides tongue structure on the backrest substrate, its minor face and backrest substrate are connected, long limit is unsettled; Make tongue structure produce certain elasticity, like this, after cushion is wrapped in the skeleton outside; Can enrich the face shaping of seat, increase the elasticity of seat critical positions such as resting the head on, waist leans on, the comfort level that is seated is improved; Its good looking appearance, simple in structure.

The specific embodiment

Below through embodiment and combine accompanying drawing, the technical scheme of the utility model is further specified.

Embodiment 1:

Seat headrest or waist shown in Fig. 1-3 lean on skeleton structure; Has backrest substrate 1; The headrest positions lateral arrangement of said backrest substrate has certain flexible tongue structure 2, and said tongue structure is asymmetric U-shaped cross sections, both sides, and the minor face 22 of its tongue structure is fixedly connected with said backrest substrate 1; The long limit 21 of tongue structure is hanging shape, makes circular arc portion produce certain elasticity; Tongue structure is provided with waling, to strengthen tongue structure intensity.

Embodiment 2:

Has backrest substrate 1; The headrest positions of said backrest substrate and waist lean on the position lateral arrangement to have certain flexible tongue structure 2; Said tongue structure is asymmetric U-shaped cross sections, both sides; The minor face 22 of its tongue structure is fixedly connected with said backrest substrate 1, and the long limit 21 of tongue structure is hanging shape, makes circular arc portion produce certain elasticity; Tongue structure is provided with waling, to strengthen tongue structure intensity.

Embodiment 3:

Have backrest substrate 1, the waist of said backrest substrate leans on the position lateral arrangement to have certain flexible tongue structure 2, and other are identical with embodiment 1.

Embodiment 4:

Said tongue structure is asymmetric U-shaped cross sections, both sides, and minor face 22 sides of its tongue structure are provided with outside bending 23, on the width of tongue structure longitudinal groove are arranged, and make whole tongue structure have better elasticity.Other and previous embodiment are together.
