The invention discloses a mechanical triggering type seat backrest side wing adjusting mechanism, and relates to the field of seat backrests. The mechanical triggering type seat backrest side wing adjusting mechanism comprises two side wing supporting plates arranged on the two sides of a seat backrest frame respectively and triggering plates in one-to-one correspondence with the side wing supporting plates, and the two triggering plates are oppositely arranged on the inner side of the seat backrest frame. The two ends of each trigger plate are connected with the two ends of the corresponding side wing supporting plate through swing arms respectively, the swing arms are hinged to the seat backrest frame respectively, the two trigger plates are connected through at least one elastic piece, and when the trigger plates move under extrusion force towards the rear portion of the seat backrest frame, the elastic pieces are connected through the elastic pieces. The swing arms drive the corresponding side wing supporting plates to rotate towards the middle of the seat backrest frame to support the side portions of the human body. The mechanical triggering type seat backrest side wing adjusting mechanism triggers the side wing supporting action by means of the pressure naturally and backwards applied to the seat backrest by the back when a passenger sits on the seat backrest, the starting action operated by a user is omitted, and the mechanical triggering type seat backrest side wing adjusting mechanism has the advantages of being simple and reliable in structure and low in cost.
一种机械触发式的座椅靠背侧翼调节机构,涉及座椅靠背领域。机械触发式的座椅靠背侧翼调节机构包括两个分别设于座椅靠背框架两侧的侧翼支撑板及与侧翼支撑板一一对应的触发板,两个触发板相对布置地设于座椅靠背框架的内侧,每个触发板的两端分别通过摆臂与对应的侧翼支撑板两端连接,各个摆臂分别与座椅靠背框架铰接,两个触发板之间通过至少一个弹性件连接,触发板受到朝向座椅靠背框架后方的挤压力移动时,使摆臂带动对应的侧翼支撑板向座椅靠背框架中部转动支撑人体侧部。机械触发式的座椅靠背侧翼调节机构依靠乘员乘坐时背部自然向后对座椅靠背施加的压力来触发侧翼支撑动作,省去用户操作的启动动作,具有结构简单可靠、成本低廉的优点。
