一種汽車(chē)座椅頭枕調(diào)節(jié)機(jī)構(gòu)
本技術(shù)涉及汽車(chē)座椅配件領(lǐng)域,尤其是涉及一種汽車(chē)座椅頭枕調(diào)節(jié)機(jī)構(gòu)。
技術(shù)介紹
現(xiàn)有的頭枕前后調(diào)節(jié)方式主要有兩種:一種是通過(guò)頭枕?xiàng)U頂部直端的軸心旋轉(zhuǎn),無(wú)極調(diào)節(jié)或棘輪式有級(jí)前后旋轉(zhuǎn)調(diào)節(jié)。缺點(diǎn)是隨著頭枕調(diào)節(jié)角度的變化,改變了頭枕與乘員頭部的接觸部位的高度和接觸面積,和頭枕對(duì)頭部支撐力的方向和角度,在車(chē)輛后撞的鞭撻中將會(huì)使人體頭部在與頭枕撞擊使產(chǎn)生不利于頸椎的發(fā)作用力,從而使人體頸椎受到較大的外力損傷。第二種是平行四邊形四連桿裝置實(shí)現(xiàn)頭枕的前后平移,缺點(diǎn)是使用棘輪裝置實(shí)現(xiàn)有級(jí)調(diào)節(jié),零部件較多,結(jié)構(gòu)復(fù)雜;且,其只能實(shí)現(xiàn)從后向前的單方向調(diào)節(jié),操作體驗(yàn)不人性化。因此,實(shí)有必要設(shè)計(jì)一種汽車(chē)座椅頭枕調(diào)節(jié)機(jī)構(gòu),以克服上述問(wèn)題。
技術(shù)實(shí)現(xiàn)思路
為解決上述問(wèn)題,本技術(shù)提供了一種設(shè)計(jì)緊湊,強(qiáng)度更高,能夠無(wú)級(jí)調(diào)節(jié)頭枕的前后位置,從而對(duì)使用者達(dá)到較好的頭部的支撐,同時(shí)有向前和向后的限位裝置,防止頭枕調(diào)節(jié)范圍過(guò)度,另一方面,也降低在車(chē)輛后撞時(shí)的頭部鞭撻損傷;同時(shí),也將使得駕乘者在車(chē)內(nèi)休息時(shí)通過(guò)調(diào)節(jié)頭枕前后位置使頭頸得到更加舒適的承托和支撐的汽車(chē)座椅頭枕調(diào)節(jié)機(jī)構(gòu)。本技術(shù)提供的一種汽車(chē)座椅頭枕調(diào)節(jié)機(jī)構(gòu),包括:頭枕?xiàng)U、殼體、安裝座、左安裝板、右安裝板、前傳動(dòng)板、后傳動(dòng)板、彈簧片;所述彈簧片下端活動(dòng)套設(shè)在所述頭枕?xiàng)U上端;所述安裝座固定在所述頭枕?xiàng)U上端,且所述安裝座活動(dòng)安裝在所述彈簧片上;所述前傳動(dòng)板下端鉸接在所述安裝座前端,所述后傳動(dòng)板下端固定在所述彈簧片上;所述左安裝板和所述右安裝板左右相對(duì)設(shè)置,所述左安裝板和所述右安裝板兩個(gè)安裝板上端通過(guò)前軸銷(xiāo)和后軸銷(xiāo)兩個(gè)軸銷(xiāo)連接;所述前傳動(dòng) ...
