Abstract

A seat comprises a seat face and seat feet arranged under the seat face. A supporting cushion body made of independent bubble foam materials is arranged above the seat face. A gel layer is arranged above the supporting cushion body. A connecting layer (medium/foam) capable of connecting the gel layer and the supporting cushion body is arranged between the gel layer and the supporting cushion body. A coating layer arranged above the gel layer can coat the supporting cushion body, the connecting layer and the gel layer above the seat face to form a seat cushion. The seat cushion is durable and environment friendly, and enables the seat to be excellent in rebound resilience, support property and loose pressure cushion property.

The specific embodiment

At first see also Fig. 1, a kind of embodiment of armchair structure improvement of the present utility model, the structure that has wherein shown a kind of seat comprises: seat 10 and the chair pin 20 of being located at the below of seat 10, what seat 10 adopted is for example plank of hard material, metal, plastic cement or other similar material manufacturings, basic condition is to possess the structural strength that is enough to grantee's body weight.Wherein, the top of seat 10 have adopt that the separated foam expanded material makes one support buffer body 30(as shown in Figure 4), above supporting buffer body 30, has a gel layer 40, between gel layer 40 and support buffer body 30, also has an articulamentum 50, can and support buffer body 30 with gel layer 40 links together, above gel layer 40, also has a clad 60 in order to will support buffer body 30, the top that articulamentum 50 and gel layer 40 are coated on seat 10 becomes chair cushion, and then it is good to allow seat have a kind of rebound performance, supportive and the loose resiliency of pressing are good, and have the chair cushion of environmental protection and the effect such as durable.

And the structure-improved of above-mentioned chair cushion part also applicable to the chair back 70 in order to the support human body back, has seat or the sofa of the chair back 70 as shown in Figure 2, and the office seats with chair back 70 shown in Figure 3.

A kind of embodiment structure according to the improvement of the utility model armchair structure, the support buffer body 30 of wherein being located at seat 10 tops is a kind of independent thermoplasticity foaming body basically, in other words be exactly a kind of expanded material with separated foam, support buffer body 30 and can be wherein any of crosslinked foaming polyethylene (PE) or cross-linked and foamed polypropylene (PP), compare with traditional perforating expanded material, crosslinked foaming PE and crosslinked foaming PP are a kind of expanded materials with separated foam, have good resilience and supportive, durable, lightweight and environmental protection.

Support buffer body 30 and can adopt wherein any of crosslinked foaming polyethylene (PE) with 3 to 30 times of foam volumes or cross-linked and foamed polypropylene (PP), can reach the good effect of lightweight quantification and supportive; At a kind of embodiment structure of the present utility model, the thickness that supports buffer body 30 can be between 1 to 10 centimetre, in order to cooperate the kind of seat and need to do suitable collocation, particularly, supporting buffer body 30 can be to only have single single layer structure (as shown in Figure 4), also can be the sandwich construction (as shown in Figure 5) that a plurality of support buffer bodies 30 are stacked, look closely the required thickness of chair cushion and determine.

A kind of embodiment structure according to the improvement of the utility model armchair structure, wherein at gel layer 40 with support articulamentum 50 between the buffer body 30, its function is as can and supporting the medium that buffer body 30 links together with gel layer 40, a kind of embodiment of articulamentum 50 is that to select foam be material, gel layer 40 can cohere a side surface at articulamentum 50 by the mode of gluing, support buffer body 30 same also be to cohere opposite side surface at articulamentum 50 by the mode of gluing, so, just gel layer 40 firm sticking together can be fixed on the top of supporting buffer body 30, because gel layer 40 is to be made by gel (Gel), has excellent loose pressure buffer effect, the support buffer body 30 that cooperates again the below, in human body sits thereon, can provide excellent loose pressure buffering effect and good supportive, and gel rubber material has refrigerant and nice and cool characteristic comfortable body sense more can be provided.And binder couse 50 is the foam material, has equally loose effect of pressing concurrently.

Clad 60 can select dermatine (such as polyvinyl chloride (PVC) or polyurethane (PU) dermatine), staple fibre cloth and natural fiber cloth any material wherein to make.

Fig. 6 is a kind of embodiment structure of the utility model armchair structure improvement, wherein between gel layer 40 and clad 60, also has a tissue layer 80, tissue layer 80 can select the similar material with telescopic resilience ability of knitted or woven fabrics or adhesive-bonded fabric or other wherein any, in order to comfortable and better sense of touch to be provided.

Fig. 7 is a kind of embodiment structure of the utility model armchair structure improvement, support buffer body 30 wherein also has a plurality of air-vents 31, these air-vents 31 axially can to bear the direction of weight parallel or vertical with chair cushion, clad 60 also has perforation 61 in the position that communicates with air-vent 31, when chair cushion is subject to the external force extruding, just the gas in the air-vent 31 can be discharged or sucked via perforation 61, and then reach the effect of ventilative heat radiation; Because support buffer body 30 is to adopt crosslinked foaming polyethylene (PE) or cross-linked and foamed polypropylene (PP) any material wherein to make, has good resilience, support buffer body 30 a plurality of air-vents 31 when being subject to the external force extruding, can not produce too large distortion yet, therefore the effect of ventilative heat radiation can be provided.

Armchair structure improvement of the present utility model can be applied to couch or office chair or other chair tools, and indefinite seat applications field.

Although the utility model discloses as above by the above embodiments; so it is not to limit the utility model; anyly have the knack of alike skill person; within not breaking away from spirit and scope of the present utility model; when can doing a little change and retouching, do not break away from the modification that spirit of the present utility model does in every case and all should be included in the utility model scope required for protection.
