Technical Field

The present invention relates to a seat cushion, and more particularly, to a composite seat cushion.

Background

The cushion is used for automobiles, steamships, airplanes and the like, such as a cushion used on a fixed seat, the use time of a user is long, and the cushion is particularly used for medical instruments such as a wheelchair and a cushion on a walking aid, besides the comfort requirement, the cushion also has high requirements in the aspect of health care, such as fatigue resistance and reduction of bedsore risk caused by long-time sitting.

Disclosure of Invention

Utility model purpose: the utility model aims at providing a can compromise compound seatpad that the travelling comfort of a long time is sat and gas permeability, holding power are strong.

The technical scheme is as follows: compound seatpad, including seatpad core and the seatpad overcoat of parcel outside the seatpad core, the seatpad core is including elastic layer, filament 3D macromolecular layer and the thick silk 3D macromolecular layer of arranging in proper order, elastic layer, filament 3D macromolecular layer and thick silk 3D macromolecular layer thickness ratio are 3 ~ 4: 2: 2, the density ratio of the thin filament 3D high polymer layer to the thick filament 3D high polymer layer is 2-3: 4.

wherein, the elastic layer is a sponge layer or a latex layer, the density of the elastic layer is at least 85 kg/cubic meter, and the sitting feeling of a user can be comfortable.

Wherein, the elastic layer thickness is 30 ~ 40mm, can not too soft when can bring comfortable sitting to feel for the user, leads to the holding power not enough.

Wherein, the elastic layer is covered with a mesh cloth cover, and the mesh cloth cover is provided with a zipper, which is convenient for cleaning and replacing the elastic layer.

Wherein, the density of the filament 3D polymer layer is 40-60 kg/cubic meter, and the air permeability is good.

Wherein, filament 3D polymer layer and thick silk 3D polymer layer are POE polyolefin elastic material, and filament 3D polymer layer silk diameter is 0.4 ~ 0.6mm, and thick silk 3D polymer layer silk diameter is 0.8 ~ 1.0mm, can provide sufficient softness, holding power and gas permeability, through sewing up fixed connection, avoids the drunkenness between the two-layer.

Wherein, the side of the seat cushion outer sleeve is mesh cloth, the back is wear-resistant anti-skidding oxford cloth, and the surface is breathable cloth, so that the breathability of the seat cushion is improved.

Wherein, the back of the seat cushion outer sleeve is sewed with a cross-shaped hair surface paste, which is convenient for fixing the seat cushion and the seat.

Wherein, the seat cushion jacket is sewed with a zipper or a hidden zipper, which is convenient for replacing and cleaning the seat cushion core.

Has the advantages that: compared with the prior art, the utility model, its advantage is: 1. the cushion layer contacting with the human body is made of latex or high-elastic sponge, is soft in texture, is independently coated with a breathable cloth cover and contacts with the human body, and the riding comfort is ensured; 2. 3D high polymer materials with different hardness are utilized to provide enough support for the elastic layer, meanwhile, the sitting pressure can be dispersed, the integral air permeability of the seat cushion is enhanced, the damp and heat are quickly discharged, and the risk of bedsore generation is reduced; 3. the cost is lower, and the maintenance is convenient.

Drawings
