Abstract

The utility model relates to a human body supporting device, comprising a supporting bottom board. A torsion balancing device is supported on the surface of the supporting bottom board. The torsion balancing device comprises a C-shaped plastic board spring. A plastic tube is integrally formed on the middle part of the bottom of the plastic board shape spring along transverse direction. The plastic tube is contacted with the supporting bottom board. The plastic board shape spring comprises two free ends, and a pressure-bearing surface is formed on each free end. The utility model has very few components, strong integrity and convenient manufacture.

Description

Human body support equipment

The utility model relates to a kind of human body support equipment, particularly seat and back cushion.

Existing seat and back cushion can not provide uniform supporting to the human body that presses thereon, its main cause is that the human body back appearance is irregular curved surface, some back cushion, contacts with fixed bearing thereby promptly form many projectioies human body entire back when human body presses on it in the predetermined fixed position of back cushion so that provide more uniform supporting to human body by following manner.Yet above-mentioned fixed back cushion can not form any reaction pressure when the supporting human body.

The purpose of this utility model is to provide a kind of novel human body support equipment, thereby this equipment can provide uniform supporting to human body to the human body generation reaction force that presses thereon, and this equipment used unit is few in addition, makes simple.

Above-mentioned purpose of the present utility model is to realize by the human body support equipment of following structure, this equipment comprises bearing plate, this plate surface is provided with the torsion balance device, this device comprises c-shaped plastic plate shape spring, this spring comprises first and second free ends of relative extension, wherein each free end is formed with and can bears the pressure-bearing surface of being exerted pressure, and laterally becomes integral body to be formed with plastic tube along it in this plastic plate shape spring bottom surface, and this pipe contacts with bearing plate.

On bearing plate, can be supported with a plurality of torsion balance devices.

Its fore-and-aft tilt relatively of the both ends of the surface of above-mentioned plastic tube, above-mentioned plate shape spring inner face is formed with reinforcement.

Be installed with fixed bar in the above-mentioned plastic tube, these bar two ends are fixed on the bearing plate.

The advantage of human body support equipment of the present utility model is that entire equipment includes only two kinds of parts, i.e. bearing plate and torsion balance device, and used unit is few, and globality is strong, and is simple in structure, easy to make, and whole in addition spring is made of plastics, thereby can reduce cost.

Below in conjunction with accompanying drawing the utility model is described in detail.

Fig. 1 is the perspective view of the torsion balance device in the human body support equipment of the present utility model;

Fig. 2 is the plane of human body support equipment of the present utility model;

Fig. 3 is the elevation of human body support equipment shown in Figure 2;

Fig. 4 is the side view of human body support equipment shown in Figure 2.

The torsion balance device 3 that shown in Figure 1 is in the human body support equipment of the present utility model, this device 3 comprises that C moulds flitch shape spring part 4, this spring part 4 comprises two opposed free ends 5,5 ', these two free ends form the plane pressure-bearing surface so that the supporting to human body to be provided, become integral body to be formed with plastic tube 7 near this middle part, spring part 4 bottom surfaces, shown in Fig. 2～4, this pipe 7 is positioned on the bearing plate 2, two end faces of this pipe 7 are the scarf 8 that relative spring part 4 bottom surfaces tilt, 8 ', see this scarf 8 from Fig. 2,8 ' is ellipsoid, thereby adopt above-mentioned shape can make spring part 4 produce comfort when making the people press thereon along laterally having necessarily to rock, why adopt pipe 7 to be because when needed can be by penetrating the fixed bar of this pipe 7, and spring part 4 can not be produced the mode that this fixed bar is fixed in bearing plate 2 to move relative to bearing plate 2.The advantage of the human body support equipment of said structure is only to comprise generally speaking two kinds of parts, makes simple and conveniently, and cost is low.

Human body support equipment of the present utility model can be widely used in used for vehicle chairs such as sofa, chair, Wheelchair, automobile, train, steamer or aircraft, and hospital's training (physiotherapy, massage, dentistry) is with chair or bed, hairdresser's chair, pillow, general mattress.Thereby it also can be made back cushion separately and can be placed on the existing human body support device and use in addition.
