Detailed Description

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below.

Embodiments of the present invention will now be described in detail with reference to the accompanying drawings. Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.

Further, although the terms used in the present invention are selected from publicly known and used terms, some of the terms mentioned in the description of the present invention may be selected by the applicant at his or her discretion, the detailed meanings of which are described in relevant parts of the description herein.

Furthermore, it is required that the present invention is understood, not simply by the actual terms used but by the meaning of each term lying within.

Fig. 1 is a schematic structural view of the self-adaptive waist support of the utility model mounted on the backrest of the chair. Fig. 2 is an enlarged view of a portion a in fig. 1.

As shown in fig. 1 and 2, the present invention discloses a self-adaptive waist support, which is installed at the lower part of a suspension frame 10 of a seat back, the self-adaptive waist support comprises a waist support main body 20, a plurality of first hooks 21, a plurality of second hooks 22 and a positioning rope cable 30, both ends of the positioning rope cable 30 are fixed on an outer frame 40 of the seat back, and the lower part of the suspension frame 10 is spanned. Wherein, both ends of the lumbar support body 20 are inserted into both ends of the suspension frame 10, and cross over the lower portion of the suspension frame 10. The first hooks 21 are respectively disposed at the upper and lower ends of the lumbar support main body 20, and are connected to the suspension frame 10. The second hook 22 is transversely arranged on the waist support main body 20 and is connected with the positioning rope 30. When the occupant is offset from the seat center O1, the adaptive lumbar support moves along the positioning cable 30 until the seat back is fully supported.

Preferably, the suspension frame 10 includes left and right vertical rods 11 arranged longitudinally in parallel and a plurality of suspension springs 12, the suspension springs 12 being laterally connected between the left and right vertical rods 11 in spaced and parallel relation to each other. The suspension spring 12 is here preferably a wire suspension spring.

The suspension frame 10 further includes a positioning rod 13, and the positioning rod 13 is fixed to the suspension spring 12 in the vertical direction. The positioning rod 13 is preferably a plastic tube here, and the positioning rod 13 is located at the center position of the suspension frame 10.

Further, the first hooks 21 extend outward along the upper and lower ends of the lumbar support body 20, respectively, to form hook portions, through which the suspension springs 12 are connected. The second hook 22 is connected to a positioning cable 30, where the positioning cable 30 is preferably a steel cable.
