Abstract

The utility model relates to a new structural design of a seat-back cushion, which has a double-layer structure that is compounded by two foamed plastic layers of different stiffness. A surface layer adopts harder material (such as EVA), and the upper side of the surface layer is provided with round table-shaped or cylindrical bulges and air holes. A bottom lining layer adopts flexible material (such as urethane) and is also distributed with corresponding air holes. The whole body of the utility model, therefore, has moderate stiffness with good air permeability, and especially massage heads that are arranged at the top ends of the bulges can simultaneously achieve the effect of massage.

Description

Ventilating massage seat, back cushion

This utility model belongs to a kind of daily living article, specifically is used for and seat or the supporting articles for use of sofa.

High-grade seat (comprising sofa) has been widely used in family, office, car, ship, aircraft and occasion that all have the people to have a rest and stop.At present, attractive in appearance and the luxurious style of outward appearance is not only paid attention in the popular design of society institute, more comfort and the health care during the emphasis use.Yet traditional design adopts leather, fabric and the urethane fat base material as seat, back cushion more at present.Its breathability is relatively poor, and softness is had a surplus, and elasticity is relatively poor and cause user displacement difficulty.Human body easily produces local pyrexia and perspires, increased sense of discomfort with seat, the back cushion contact area is too big.Life-time service easily produces fatigue, and summer, its shortcoming was particularly remarkable.

The purpose of this utility model provides a kind of seat, structural design that back cushion is new, and make it not only have air permeability and good, and can make the function that produces part massage allaying tiredness and health-care recovery, the soft or hard appropriateness, comfortable durable.

For eliminating the disadvantage in the design in the past, this utility model has taked to have different elasticity and the compound structure of soft degree foamed plastic especially.Its surface layer should be taked elastic modelling quantity higher material, for example EVA.It is big to overcome contact area by its direct contact human body, the disadvantage of displacement difficulty.The end liner layer is positioned at takes more softish material to make below the surface layer, and for example potassamide acid second fat can replenish the not enough defective of surface layer pliability like this, makes the whole comfortable sensation of not losing.The bonded double-decker of soft or hard can overcome shortcoming in the past, does not lose original advantage again.Surface layer takes EVA and so on that the material of higher elasticity modulus is arranged, can also on the shaped design of surface layer, add equally distributed projection, cause with the multiple spot of human body and contact, and be distributed with pore, so not only can further reduce the contact area of human body and seat, back cushion, but also can improve the permeability of material by pore, the person has more ideal impression to make the life-time service.So the end liner layer also should be evenly distributed with pore, and corresponding with the surface layer pore, with the permeability of the whole seat cushion of effective improvement.Two-layer compound can directly the gummed, also integral body can be formed complete seat, a back cushion with the lining envelope.

How further specify the purpose of this utility model below in conjunction with accompanying drawing realizes.

Fig. 1 is the view during this utility model uses.

Fig. 2 is the attached cutaway view of looking of a seat, back cushion.

Fig. 3 is that the A-A of Fig. 2 is to view.

Fig. 4 is the massage head structural representation.

Wherein 1 be meant seat, back cushion, the 2nd, surface layer, 2A are the truncated cone-shaped projections, and 2B is the round platform cavity, and 2C is a pore, and 2D is a cylindrical protrusion, 2D4 is a massage head, the 3rd, end liner layer, 3A are pores, the 4th, lining.

From accompanying drawing as can be seen, surface layer 2 is provided with two kinds of projections among the design, truncated cone-shaped 2A and right cylindrical 2D, and round platform 2A can be designed to hollow form, has promptly had cavity 2B.Pore 2C promptly designs in cavity 2B coaxial, concentric with round platform 2A.Whole truncated cone-shaped projection 2A becomes the strong point that mainly bears body weight at surface layer 2 uniform distribution.Pore 2C and 3A are coaxial, and corresponding the distribution constitutes distinctive penetrating depressed structure.

Right cylindrical projection 2D can increase the area of grantee's body weight, can also embed the massage head 2DA that hard material is made on the straight cylinder top in addition.Suitably distribution can make the effect that produces massage on the seat when taking a seat, and can lessen fatigue, and prevents sitting and the multiple occupation disease that forms.

Seat, the every layer of bionical shape that can make middle nick of back cushion are coincide buttocks or back curve with it, can increase comfort effectively, liked by the people.

By the seat that above structural design is made, its soft or hard appropriateness, ventilative good, can produce massage effect, make to be specially adapted to car and boat driver and clerk by the degree of fatigue of taking for a long time that significantly reduces that the excellent popularization prospect will be arranged.

Claims
