Abstract

The utility model relates to human body supporting equipment, 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, a spring and a swing member. The swing member is arranged between the spring and the supporting bottom board. The top of the swing member is provided with a convex part. The spring comprises two free ends, and each free end is provided with a pressure-bearing surface. A hole is formed near the middle part of the spring on one side opposite to the free ends, and the convex part of the swing member can be embedded in the hole. The utility model has very few members 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 the external pressure of being exerted pressure, in the spring with the middle part of an above-mentioned free-ended relative side near form porose, between plastic plate shape spring and bearing plate, be provided with and wave parts, this bottom surface of waving parts is supported on the bearing plate, this end face that waves parts has protuberance, and this protuberance embeds in the hole that forms in the above-mentioned spring.

On bearing plate, can support a plurality of torsion balance devices.

The above-mentioned parts bottom surface of waving can curved.

The advantage of human body support equipment of the present utility model is to adopt the monoblock type flat spring, thereby simple in structure, easy to make, 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 elevational schematic view of human body support equipment;

Fig. 2 is the perspective exploded view of the torsion balance device in the human body support equipment.

As illustrated in fig. 1 and 2, human body support equipment 1 of the present utility model comprises bearing plate 2, bearing plate 2 upper supports have torsion balance device 3, this device 3 comprises that C moulds flitch shape spring part 4, this spring members 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, in this spring part 4 with free end 5, have hole 6 near 5 ' the relative middle side part, be provided with between spring members 4 and bearing plate 2 and wave parts 7, this waves parts 7 bottoms is arc surfaced, its end face has protuberance 8, and this protuberance embeds in the hole 6 in the above-mentioned spring part 4.

Human body support equipment of the present utility model can be widely used in sofa, chair, Wheelchair, used for vehicle chairs such as 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.

Claims
