改良型椅背Improved seat back

本創作係關於一種改良型椅背，尤指一種可與椅座組合為椅子之椅背。This creation is about a modified seat back, especially a chair back that can be combined with a seat.

為提供使用者不同需求的椅子，近年來市面上可見及的椅子型態相當多樣，除了藉由各種可調整的機構，使椅子及扶手之高低可調整外，更可見及以舒適性佳作為訴求的椅子，因此，在椅背與椅座之銜接處普遍設有彈性構件，以使乘坐者背部頂靠於椅背時，藉由彈性構件，使身體能適當的伸展。In order to provide chairs for different needs of users, the types of chairs that can be seen on the market in recent years are quite diverse. In addition to the adjustable heights of the chairs and armrests, the visibility and comfort are better. Therefore, the elastic member is generally provided at the junction between the seat back and the seat so that the occupant can properly extend the body by the elastic member when the back of the seat is placed against the back of the seat.

惟因長時間乘坐椅子時，通常是背部最易產生酸痛，故須適時加諸背部舒緩力，以減緩身體的疲憊感，但目前的彈性構件係設置於椅背與椅座之銜接處，若要使椅背前後搖動而使背部適時伸展，因彈性構件係位於椅背之下端處，故背部須施以較大的推力來能使椅背搖動，方能使身體伸展，因此反而造成身體另種負擔。However, when you are riding a chair for a long time, it is usually the back that is most prone to soreness. Therefore, it is necessary to add back relief to the body to relieve the fatigue of the body. However, the current elastic members are placed at the joint between the seat back and the seat. To make the back of the chair rock forward and backward so that the back stretches at the right time, because the elastic member is located at the lower end of the back of the chair, the back must be applied with a large thrust to shake the back of the chair, so that the body can stretch, thus causing the body to a burden.

因此即有業者希藉由高彈性之材質來製造椅背，或是使椅背為彈性帶、彈性布之型態，藉此增加椅背的彈力，然不論是藉由材料之特性或是彈性帶、彈性布，乘坐一段時間後，因彈性疲乏的緣故，即使椅背的彈力逐漸降低，而無法使其舒適性得以持續。Therefore, the manufacturer has to use the material of high elasticity to make the back of the chair, or to make the back of the chair elastic and flexible, thereby increasing the elasticity of the back of the chair, whether by the characteristics or elasticity of the material. Belt, elastic cloth, after a period of riding, due to the fatigue of the elastic, even if the elastic force of the back of the chair is gradually reduced, it can not make its comfort continue.

故鑑於目前椅子之椅背無法提供適當的彈力，使乘坐者無法舒適地乘坐，本創作者乃思及，若能將椅背之結構進一步研發，使椅背之彈力提昇，即可使乘坐時更加舒適。Therefore, in view of the fact that the back of the chair can not provide the appropriate elastic force, so that the occupant can not ride comfortably, the creator thinks that if the structure of the seat back can be further developed, the elasticity of the back of the chair can be improved, so that the ride can be made. More comfortable.
