Embodiment

[0012] 1. If Figure 1 to Figure 2 As shown, a combined seat lumbar support frame assembly includes a movable lumbar pad (1), a plastic buckle (2), a bracket beam (3), a multi-stage hinged movable rod (4), and a multi-stage hinge joint (5). ), a multi-stage twisted fixed rod (6), a movable casing (7), an outer casing (8), a connecting rod (9), and a straight-line pull (10). It is characterized by:

[0013] A combined seat lumbar support frame assembly, wherein a movable lumbar pad (1) is formed by compounding a hard plate and an elastic material, and the elastic material is directly supported on the waist of a human body. A pair of plastic clips (2) are fixed on the hard plate of the movable lumbar pad (1) with screws, the bayonet of the plastic clips (2) is stuck to the bracket beam (3), and the movable lumbar pad (1) passes through the plastic clips. The buckle (2) can be rotated around the bracket beam (3) at a certain angle, so that the movable lumbar pad (1) can adapt to...

Abstract

The invention relates to a combined seat waist support frame assembly and proposes a scheme to overcome the defect that an integral backrest of a conventional chair cannot provide effective support and health care effects for a human body: an independent movable waist cushion (1) capable of moving independently is arranged on a health care chair body; and the waist cushion can perform arc rotation, front-back swing and lifting motion around a fulcrum respectively, provides accurate position support for the human body, and can perform local pressing health care motion. The combined seat waist support frame assembly comprises the movable waist pad (1), a plastic buckle (2), a bracket cross beam (3), a multi-stage hinge movable rod (4), a multi-stage hinge joint (5), a multi-stage hinge fixed rod (6), a movable sleeve (7), an outer sleeve (8), a connecting rod (9) and a linear puller (10). The combined seat waist support frame assembly has the advantages of being reasonable in structural design, high in practicability and capable of being accurately adjusted to the lumbar vertebra part for continuous supporting and pressing health care.

Description

technical field [0001] The invention belongs to the technical field of seats, in particular to a combined seat waist support frame assembly. Background technique [0002] In modern life, people spend more and more sedentary time in the office and relatively less time to participate in physical exercise. As a result, people are prone to lumbar and cervical spine diseases. Therefore, there are many kinds of improvements to traditional chairs, such as electric massage health chairs, which can perform electric massage movements on the lower back and cervical vertebra of the human body, but the products are expensive and expensive, and cannot be widely used. Most office chairs are traditional chairs with fixed backrests. The fixed backrest of chairs is generally insufficient in design, but only provides support for the back, but lacks support for the waist. People sitting for long periods of time will cause the waist to be involved, which is also the main reason for lumbar muscl...
