Description of the invention (/) [Technical Field] (Please read the precautions on the back before filling this page) The present invention relates to a tailor-made wheelchair cushion and back The manufacturing method and device of the cushion, in particular, a finished cushion and back cushion are made entirely according to the curve of the body curve of the patient's actual ride, in order to improve the comfort of the patient when sitting in 5 seats and provide good support. Manufacturing method and device of tailor-made wheelchair cushion and back cushion for avoiding bedsores in patients who have been in wheelchairs for a long time. [Previous technology] The cushions and back cushions of conventional wheelchairs are usually mass-produced, and their dimensions are exactly the same. When patients ride on the cushions and back cushions, the cushions and back cushions are not designed according to the actual body shape of the patient. As a result, the patient's body cannot fully contact the seat cushion and the back cushion, so that when a patient with no mobility or severely deformed torso rides on the wheelchair for a long time, certain parts of the patient's long contact with the seat cushion and the back cushion are: It is easy to produce bedsores, or skin peeling due to excessive pressure on the ride. Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs to improve the above-mentioned shortcomings, a cushion and a back cushion made according to the patient's actual sitting posture and body shape arc came out. It uses sponges with different hardness to artificially tailor the patient's The cutting posture of the sitting posture makes the finished cushion and back cushion show the shape of the patient when riding. However, because this method is made by manual cutting, some radian parts of the human body cannot be accurately cut. The size and arc of the finished cushion and back cushion and the curve of the actual sitting and lying body curve of the patient do not fit, making the patient unable to make full contact with the cushion and back cushion, allowing the patient to ride on the cushion and back It is impossible to reach the goal of equalizing pressure at the time ___ This paper size is applicable to Chinese National Standard (CNS) A4 (210 X 297 mm) 558440 Printed by A7 B7, Employee Cooperative of Intellectual Property Bureau of the Ministry of Economy — PA020152.TWP-4 / 12 V. Description of the invention (2). In order to create a seat cushion and back cushion that can fully contact the patient's body, the use of CNC computer-assisted lathe cutting technology came out, which uses a computer to scan to obtain the patient's sitting posture and curvature when riding; ran 5 However, although this method is more advanced than the manual production method, its production cost is quite expensive. The producers need to buy related equipment and computer scanning devices before they can make seat cushions and seat cushions, which cannot be popularized. It can be seen that there are still many shortcomings in the above-mentioned conventional articles. They are not a good designer and need to be improved. 10 In view of the various shortcomings derived from the conventional wheelchair cushions and back cushions, the inventor of this case has been eager to improve and innovate. After years of painstaking and meticulous research, he has finally successfully developed this tailor-made wheelchair cushion and back cushion. Manufacturing method and device. [Objective of the Invention] 15 The purpose of the present invention is to provide a wheelchair cushion and a back cushion which are made according to the actual sitting posture and curvature of the patient, so that the patient's body can fully contact the cushion and the back cushion for comfort. Manufacturing method and device of tailor-made wheelchair cushion and back cushion for riding and equalizing purposes. A secondary objective of the present invention is to provide a tailor-made wheelchair cushion and back cushion with a good support force for 20-seat and back cushions to increase the patient's riding stability, provide the best riding condition and prevent joint deformation from deteriorating.

In the process of extracting the gas, the manufacturer can mold the mold taking device into the posture of the patient when riding. Once the gas extraction is completed, the mold taking device will be shaped and present the patient. The posture and radian of the actual ride; 3. Cover the plaster with the outer surface of the molding device to form a female 10 mold; 4_ Take another foaming box, which has an upper cover and a bottom cover. The bottom cover is provided with a hole for hanging the top cover. The female mold of step 3 is placed in a foaming box, and the containing space of the female mold corresponds to the hole in the bottom cover; 15 5. Cover the female mold with an isolation mold, and the area of the spacer mold is larger than that of the hair mold. The area of the bubble box, and plastic particles are placed on the isolation mold. The plastic particles can fill the gap between the female mold and the foaming box, so that the positioning of the female mold will not move arbitrarily. Cover the upper cover, and then turn the foam box so that the bottom 20 cover is facing up, so that the manufacturer can inject the foam into the female mold through the hole in the bottom cover to foam, and the foaming is completed to form the wheelchair cushion and back; 7. Put a woven fabric or leather on the cover of the seat cushion and back cushion, so that the seat cushion and back cushion of the wheelchair are completed.
