【物品用途】;本創作係提供一背墊，尤指一種放置於椅背上用於提供乘坐者背部抵靠之背墊。;【設計說明】;從各視圖觀之，主要其外觀上之特徵為：本創作之背墊呈板狀形成有一頂端與一底端，而該背墊之頂端與底端皆形成有圓弧曲線，且該背墊之頂端面積略小於該底端面積，使該頂端與底端之間的兩側外凸形成如同有大肚子之背墊外觀，又該背墊正面的中央由頂端至底端凹設有一凹槽，而該凹槽內凸設有三個圓形凸粒，並由凹槽將背墊對稱分隔兩相同形狀，該背墊最外凸的位置凸設有橫向弧形凸條，且該兩弧形凸條之間以一小段板片跨過凹槽而形成連接，並由連接端向外側體積漸大，又於該背墊鄰近頂端處形成有二個呈平面狀之凸部，且該兩凸部於外觀上近似人體肺部之造型，另於該弧形凸條與凸部之間皆凸設有一銳角三角形之凸體，使該背墊正面間隔形成有多處的相對內凹部位，而該弧形凸條表面與凸部處各凸設有二個圓形凸粒，使其外觀有別於一般之簡單設計，誠為一獨特穩重之新式樣設計，應已符合設計專利成立要件，爰依法提出申請，懇祈鈞局早日惠准專利，至感德便。[Use of article]; This creation provides a back cushion, especially a back cushion placed on the back of a chair to provide support for the rider's back. ;[Design Description];From each view, the main appearance features are: the back cushion of this creation is plate-shaped with a top and a bottom, and the top and bottom of the back cushion are both formed with arcs Curved, and the area of the top of the back pad is slightly smaller than the area of the bottom, so that the two sides between the top and bottom are convex to form the appearance of a back pad with a big belly, and the center of the front of the back pad is from top to bottom. The recess is provided with a groove, and three circular protrusions are protruding in the groove, and the groove symmetrically separates the back pad into two identical shapes. The outermost protruding position of the back pad is protruding with a transverse arc-shaped convex strip. And the two arc-shaped protrusions are connected by a short section of plate across the groove, and the volume becomes larger from the connecting end to the outside, and two planar convex parts are formed near the top of the back pad. , and the two convex parts are similar in appearance to the shape of human lungs, and an acute-angled triangular convex body is protruding between the arc-shaped convex strip and the convex part, so that the front surface of the back pad is spaced to form multiple opposite positions. The concave part, and the surface of the arc-shaped convex strip and the convex part are each provided with two round convex grains, making its appearance different from the ordinary simple design. It is a unique and stable new style design that should have complied with To establish the requirements for a design patent, you must apply in accordance with the law. We sincerely pray that the bureau will grant the patent as soon as possible.
