Problems solved by technology

[0003] However, because these hinges are made of metal material, the weight of the foldable cushion will be greatly increased, which is not conducive to carrying, and if it is used outdoors or in a wet place, such as grass, the hinges will be prone to damage. Rust reduces the service life of the foldable cushion
For related technical problems, no effective solutions have been proposed

[0028] Before the present invention is described in detail, it should be noted that in the following description, similar elements are designated by the same reference numerals.

no. 1 example

[0029] see Figures 1 to 3 , The first embodiment of the foldable seat cushion 1 of the present invention includes a seat cushion mechanism 2 and a connecting mechanism 5 .

[0030] The seat cushion mechanism 2 includes a plate-shaped seat cushion unit 21 and a seat back unit 22 which are placed side by side along a transverse folding line L2, and two are respectively disposed between the seat cushion unit 21 and the left side of the seat back unit 22 and the armrest unit 23 between the right side. The seat cushion unit 21 has two seat cushion plates 211 that lie side by side along a first longitudinal fold line L1 intersecting the transverse fold line L2, and the seat back unit 22 has two left and right sides along the first longitudinal fold line L1. Each armrest unit 23 has two armrest panels 231 that lie side by side along the transverse folding line L2. The seat cushion boards 211 , the seat back boards 221 , and the armrest boards 231 are all plate-shaped in appearance...

Abstract

A foldable chair cushion comprises a chair cushion mechanism and a connecting mechanism. The chair cushion mechanism comprises a plate-shaped seat cushion unit and a plate-shaped chair back unit which can lean against each other along a transverse folding line. The connecting mechanism comprises a first annular rope and a second annular rope which extend through the transverse folding line and are flexibly arranged on the cushion unit and the chair back unit. And the first ring rope and the second ring rope can be pulled and supported by the cushion unit and the chair back unit which are relatively unfolded along the transverse folding line, and are matched to position the cushion unit and the chair back unit in an unfolded state in which a preset angle is formed between the cushion unit and the chair back unit. Due to the fact that the first ring rope and the second ring rope have the advantages of being light in weight, easy to install and free of rusting, the foldable chair cushion has the advantages of being convenient to store, easy to carry and not prone to being rusted and damaged.

Description

technical field [0001] The invention relates to the technical field of chair cushions, in particular to a foldable chair cushion. Background technique [0002] A conventional foldable seat cushion includes a plurality of plates that are adjacent to each other along a folding line and a plurality of hinges connected and arranged between the plates, and the plates of the foldable seat can pass through The hinges swing and unfold relative to the folding line, and are located in an unfolded state by leaning against each other at a specific angle. The foldable seat pad can be driven to fold and fold the plates in half along the fold line to change from the unfolded state to a folded state. [0003] However, because the hinges are made of metal material, the weight of the foldable seat cushion will be greatly increased, which is not convenient for carrying, and if used outdoors or in wet places, such as grass, the hinges will be easily damaged. rust and reduce the service life o...
