Abstract
Description
本發明係一種涉及於傢俱的技術領域,尤指座椅設置諸如腰靠墊、頭枕墊的結構,具有可調整高低位置的功能。The invention relates to the technical field of furniture, in particular to the structure of a seat such as a lumbar cushion and a headrest cushion, and has the function of adjustable height position.
人們為乘坐椅子舒適,座椅的功能設計不斷依照人體工學不斷推陳出新,比如座椅可調整高度,座椅在椅背設置有腰靠墊,腰靠墊是供背部自然向後靠時,提供腰部的支撐,緩解脊柱上的壓力,防止由於坐姿不當而產生不舒適應,比如證書號M368366「座椅之腰靠調整結構」新型專利案(下稱:專利引證前案一),其係座椅的腰靠組體,包含一靠背主體設置一支持部,支持部貫穿一縱向孔,該孔靠前方位其兩旁凹設數道間距承置部,可允許一頂推組件的兩凸部作切入於間距承置部,另對靠背主體的縱向孔靠後方其外周緣凹設一截環槽以允許按押件容置其間;藉以組設在靠背主體其間的腰靠在調整高度時,以手部按壓靠背主體後側的按押組件,以帶動頂推組件內移一併驅使其兩凸部承置部,以在調整至適合高度即放鬆按押組件,達到調節腰靠高度的目的。People are comfortable in riding the chair, and the function design of the seat is constantly updated according to ergonomics. For example, the seat can be adjusted in height, the seat is provided with a lumbar cushion on the back of the seat, and the lumbar cushion is for the back of the back to provide a lumbar support. To relieve the pressure on the spine and prevent discomfort due to improper sitting posture, such as the new patent case of certificate number M368366 "Recumbent structure of the seat of the seat" (hereinafter referred to as: Patent Prosecution Case 1), which is the waist of the seat The support body is provided with a support portion, and the support portion is inserted through a longitudinal hole. The hole is recessed on the two sides of the hole in the front direction, and the two convex portions of the thrust pushing assembly are allowed to cut into the spacing. The receiving portion further has a truncated ring groove recessed on the outer peripheral edge of the longitudinal hole of the backrest main body to allow the pressing member to be accommodated therebetween; thereby, the lumbar portion disposed between the backrest main body is adjusted by the hand, and is pressed by the hand. The pressing component on the rear side of the backrest body drives the pushing assembly to move the two convex portion bearing portions to adjust the height to the pressing component to adjust the waist height.
固然專利引證前案一讓腰靠可以方便調整高低位置,但是腰靠與按押組件是倚靠一連結件予以插穿結合,連結件一端是螺固接合於腰靠,因此腰靠與椅背之間僅有連結件的單點結合處。由於人體乘坐於座椅並非姿勢長久不動,而身體調整姿勢動作當中,腰靠與椅背的連結呈現連結件截面積的單點型態,故腰靠會隨著姿勢調整甚至座椅動作而晃動,讓乘坐者感覺腰靠的墊靠性不夠穩定,產生心理上的不舒適感;再者,腰靠的單點結合於椅背型態是採取螺紋接合,而腰靠長期被人體壓迫擠動的外力,難以避免螺紋接合有出現鬆動的顧慮,結構穩固性存有潛在性的不穩定。Although the patent citation case allows the lumbar support to easily adjust the height position, the lumbar support and the push-on assembly are inserted and joined by a connecting piece, and one end of the connecting piece is screwed to the lumbar support, so the lumbar support and the back of the chair There is only a single point of joint between the joints. Since the human body is seated in the seat, the posture is not moving for a long time, and the body is adjusted in the posture, and the connection between the waist and the back of the chair presents a single point type of the cross-sectional area of the connecting piece, so the lumbar support will be shaken with the posture adjustment or even the seat movement. The occupants feel that the cushioning of the lumbar support is not stable enough, resulting in psychological discomfort; in addition, the single point of the lumbar support combined with the back of the chair is threaded, and the lumbar support is squeezed by the human body for a long time. The external force is difficult to avoid the loosening of the threaded joint, and the structural stability has potential instability.
