Description

Lazy chair for waist

Technical Field

The utility model relates to the technical field of lazy chair equipment, in particular to a waist-supporting lazy chair.

Background

The traditional chair generally has a seat for a human body to sit down, when the human body sits on the seat, the body weight is supported by the seat, the human body physiological structure shows that the spine of the human body bears the upper body of the human body such as the head, the back and the like, and the load is quite large because the lumbar is at the lowest position of the spine, and the junction of the movable section and the fixed section is easier to be damaged. If the sitting posture of the human body is incorrect, the human body is easy to have soreness and backache except for looking mentally, even the spine and the nerve are pressed, and the health is finally affected.

Due to the curve of the spine of a human body, a gap is reserved between the backrest of a common chair and the waist of the human body, so that the chair cannot well support the waist, and the waist is uncomfortable after long-time sitting. A lumbar support unit for a seat as disclosed in chinese patent CN202021420985.0 comprises: waist back shore component and rather than rotate the waist centre gripping component of being connected, waist centre gripping component can for waist back shore component rotates the switching that realizes open mode and closed state, though above-mentioned patent also mentions waist support structure, the structure is comparatively complicated, and it is also comparatively loaded down with trivial details to launch this function simultaneously

To this end, we propose a waist-up lazy chair.

SUMMERY OF THE UTILITY MODEL

(III) advantageous effects

The embodiment of the utility model provides a lazy chair for pushing waist. The method has the following beneficial effects:

1. the utility model solves the problem that the prior function does not have the function of supporting the waist or the structure of the function of supporting the waist is too complex, can conveniently and quickly achieve the effect of supporting the waist through simple structural combination, can quickly switch the supporting waist and the conventional state, has low manufacturing cost and strong practicability.

2. Can better support the waist of the human body. When human back was faced back, can drive the back and rotate to the rear this moment, and torque spring's one end can be crooked this moment, simultaneously because the hypomere joint is fixed motionless, consequently will make the ejector pin that torque spring cup jointed more tend to the physiology curve of laminating waist, then can support the waist better.

3. Can perform a certain massage function on the waist. In the repeated action of continuous backward bending, the ejector rod repeatedly supports and breaks away from the waist, which is equivalent to realize a massage effect on the waist, and can improve the discomfort of the waist to a certain extent.

4. Through the opening and closing of the joint upper lock catch, the chair can be folded, and the chair is convenient to store.
