Abstract

The utility model relates to a wheelchair back cushion, specifically an improved structure of a wheelchair back cushion; the improved structure of a wheelchair back cushion can be clamped and fixed on a main body of a wheelchair, and can be quickly separated from the main body of the wheelchair while the wheelchair is not influenced in being folded. The utility model mainly comprises a back cushion body (40), a column grommet (30), a rotating shaft part member (50), a buckling member (60) and a fixing member (70). The back cushion body (40), which has a physiological radian, is provided with a plurality of ventilation slots (45); the rotating shaft member (50) and the buckling member (60) are both fixed to the back cushion body (40) through the fixing member (70). Because having simple structure, quick assembly and disassembly, good ventilation performance, convenient disassembly and cleaning, and a user can replace the different back cushion body (40) according to different physiological radians, the utility model has convenience, comfortableness and practicability.

Description

The improvement structure of wheel seat back pad

This utility model relates to a kind of seat back pad of taking turns, and specifically is meant a kind of can being fixed and sharp separation with the wheelchair body, and does not influence the improvement structure of the wheel seat back pad of wheelchair folding.

The existing seat back pad body of taking turns means the back pad body that is provided with on the wheelchair body, and this back pad system is made by spongy body cooperation leather or cloth products and formed, and can be convenient to the folding of wheelchair body; Yet for the user that long-term dependance on wheel chair is ridden instead of walk, this back pad body Support Position is generally not good, and regular meeting makes and causes injuries such as back pain even generation decubital ulcer by the user local compression, can't meet the needs of wheelchair user's life-time service; So someone proposes a kind of way of solution, promptly take turns between seat back pad body and user back original, insert a movable insertion type back pad, the pressure that is born with the back of releiving; Though yet this product has the effect of the local compression of slowing down, some problems of having derived also, the insertion type back pad is used often and is changed its position with moving of user health, user often need in time be adjusted the relevant position of insertion type back pad, for for the disabled patient, this product is not good design for most user; Moreover, the insertion type back pad between between the back pad body of user back and wheelchair, that is outside the wheelchair body, establish assemblies again more; when pre-folding wheelchair; as if many again burdens and burdensome for user, its practicality also reduces greatly, again; often utilize soft things such as sponge in the insertion type back pad; after used at contact user back, regular meeting was because of using position not good sultry the sweating of ventilating, and produced abnormal flavour after causing insertion type back pad absorbing sweat; produce the problem of health aspect, extremely undesirable.

The purpose of this utility model provides a kind of back pad body and is separable form, and is simple in structure, can assemble fast and dismantle, and can select draughty improvement structure of taking turns seat back pad for use according to the physiologic radian demand collocation of user.

Design of the present utility model is: it mainly includes back pad body, cylinder orifice ring, shaft element, buckle element and retaining element, back pad body tool physiologic radian, it is provided with several ventilation grooves, Gu the post orifice ring is fixedly set on the vertical pole of wheelchair body, be used with the shaft element, it is L shaped that the shaft element slightly is, and buckle element is provided with the circular arc of the vertical pole of a cooperation wheelchair body, fasten with vertical pole, shaft element and buckle element are all fixed with retaining element and back pad body.

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

The 70-retaining element

Embodiment:

Referring to Fig. 1, user uses the insertion type back pad (10) of unpack format more on existing wheelchair is used, and promptly between original back of taking turns seat back pad and user, inserts a movable insertion type back pad (10), the pressure that is born with the back of releiving; Yet many problems of but having derived.

Referring to Fig. 2-Fig. 5, this utility model mainly includes back pad body (40), shaft element (50), buckle element (60), cylinder orifice ring (30) and retaining element (70).Back pad body (40), it is moulded to be its feature with the tool physiologic radian, which is provided with several ventilation grooves (45), back pad body (40) is made by the alternate material of soft or hard matter such as foam, engineering plastic; Cylinder orifice ring (30) is fixedly set on the vertical pole (20) of wheelchair body, with welding, be spirally connected or the mode of gluing together is fixed, is used with shaft element (50) on the back pad body (40); Shaft element (50) slightly is L shaped; Vertically be a cylinder (52), laterally be that a plate (55), plate (55) are provided with circular hole (58), pass through and shaft element (50) is fixed on the back pad body (40) for retaining element (70); Buckle element (60) is provided with the circular arc of the vertical pole (20) of a cooperation wheelchair body, fastens with vertical pole (20), is holding section (65); The plate of buckle element (60) side is provided with circular hole (62), passes through and buckle element (60) is fixed on the back pad body (40) for retaining element (70); Retaining element (70) can be the retaining element that screw, rivet etc. are suitable for.

By learning in the diagram, back pad body (40) is via the collocation of shaft element (50), buckle element (60) assembly, after being installed on the cylinder orifice ring (30) on the vertical pole (20) of wheelchair body, nationality by the buckle effect of buckle element (60), make back pad body (40) firmly to be disposed on the wheelchair body to use; When the folding collection is used, is carried out in the termination of chance wheelchair, only need back pad body (40) is pushed into to the inside the vertical pole (20) of holding section (65) the disengaging wheelchair body of buckle element (60) this moment, the wheelchair body is the action of feasible folding, maybe can back pad body (40) be pulled down from the wheelchair body according to the actual needs that use.

This utility model is because simple in structure, back pad body (40) can be assembled and dismounting, performance of ventilating are good, it is easy to clean to unpick and wash, user can be changed different back pad bodies (40) according to different physiologic radians rapidly, make it to have convenience, comfortableness and practicality.
