the utility model provides a bamboo spring sofa seatpad, locates the seatpad cover in the seatpad body outside including seatpad body and cover, the seatpad body includes the elastic layer and the sponge surrounding layer that the elastic layer outside was located to the cover, the elastic layer includes bamboo spring matrix and the first non-woven fabrics layer of parcel in the bamboo spring matrix outside, bamboo spring matrix is including a plurality of non-woven fabrics bagging bamboo springs that are the matrix arrangement, a plurality of non-woven fabrics bagging bamboo springs include bamboo spring and parcel respectively and are in the second non-woven fabrics layer in the bamboo spring outside.

Further, the free height of the bamboo spring is 180 mm-200 mm, and the diameter of the bamboo spring is 30 mm-40 mm.

Further, the thickness of the sponge outer wrapping layer is larger than or equal to the free height of the bamboo spring.

Furthermore, the bamboo spring is manufactured by gluing and assembling a plurality of bamboo split pieces, winding and coiling the bamboo split pieces, and finally placing the bamboo split pieces into an oven for molding.

Furthermore, the non-woven fabric bagged bamboo springs are respectively provided with activated carbon.

Further, the active carbon is bagged active carbon.

Further, the height of the bagged activated carbon is less than or equal to the height of the bamboo spring in limit compression.

Further, the sponge outer wrapping layer is formed by bonding sponge blocks.

Compared with the prior art, the utility model has the advantages of it is following:

1. the utility model adopts the novel bamboo spring to replace the traditional metal spring material, the bamboo spring material has low cost, light weight, safety and environmental protection, can not rust and can not cause harm to the health of human body, thereby improving the environmental protection performance of the mattress, lightening the quality of the mattress and reducing the cost of the mattress; 2. each bamboo spring adopts the non-woven fabric independent packaging technology, so that each bamboo spring is stressed independently, the sofa is stressed more uniformly, the friction among the springs is reduced, and the noise generated by the friction is reduced, so that the sofa cushion has the advantages of silence, comfort, good anti-seismic performance and durability, and the springs can cooperate to provide required support for the body while independently operating and contracting; 3. the setting of the active carbon makes the sofa cushion of the utility model have the effects of moisture absorption, ventilation, deodorization and adsorption.

Detailed Description

The invention will be further described with reference to specific embodiments. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.

The present invention will be further explained with reference to the drawings and examples.

As shown in fig. 1 to 4, the bamboo spring sofa cushion comprises a cushion cover 1 and a cushion body, wherein the cushion cover 1 is sleeved outside the cushion body. The cushion cover 1 can be made of cotton cloth, real leather or microfiber artificial leather.

The seat cushion body comprises a sponge outer cladding layer 6 and an elastic layer, and the sponge outer cladding layer 6 is wrapped on the outer side of the elastic layer.

The elastic layer comprises a bamboo spring matrix and a first non-woven fabric layer 2, and the first non-woven fabric layer 2 is wrapped outside the bamboo spring matrix.

The bamboo spring matrix is formed by arranging a plurality of independent non-woven fabric bagged bamboo springs according to a matrix, and each non-woven fabric bagged bamboo spring is composed of a bamboo spring 4 and a second non-woven fabric layer 3 wrapped on the outer side of the bamboo spring 4. Adopt the solitary bamboo spring of non-woven fabrics parcel, every bamboo spring can atress alone, lets the atress more even, has reduced the friction between each spring, has eliminated the noise that the friction produced, makes the seatpad have the effect of silence, has also prolonged the life of seatpad simultaneously, provides soft comfortable sitting and sleeping experience for the people of different sizes.
