具体实施方式
下面将参考附图阐述本发明几个不同的最佳实施例,其中不同图中相同的标号代表相同的部件。下面结合附图,详细阐述本发明的实施例。
本发明的汽车安全座椅具有安全带自动调整装置,当小孩就坐后,扣上安全带扣具后,安全带可自动收紧,无需手动调整。
如图1、2所示,该汽车安全座椅1包括座椅体11以及套设在座椅体11上的座垫12。如图所示,与安全带扣具13连接的安全带10包括胯带101、腰带102及肩带103。安全带扣具13与安全带自动调节装置2中的安全带扣具固定件21(图3)扣合连接。
如图3所示,安全带自动调节装置2安装在汽车安全座椅1的座椅体11的底座111中,而安全带扣具固定件21则突出于座椅体11及底座111。如图3所示,该安全带自动调节装置2包括安全带扣具固定件21、安全带卷收器22以及设于安全带扣具固定件21和安全带卷收器22之间的连动件23。具体地,该安全带扣具固定件21包括安装件211、安装于安装件211上的转动轴212以及与转动轴212连接的插入件213。该安装件211安装在座椅底座111上,插入件213可转动地安装在安装件211上,该插入件213与安全带扣具13相扣合。
连动件23设在安全带扣具固定件21和安全带卷收器22之间,具体地,连动件23的一端固定在安全带扣具固定件21的转动轴212上,另一端延伸至安全带卷收器22并与之连接。随着安全带扣具固定件21的转动,连动件23向前或向后移动,从而将安全带卷收器22的安全带锁定或释放。下面将有详细说明。
如图4、6所示,该安全带卷收器22包括卷收器安装件221、供安全带缠绕的转轴222、位于转轴222两端的第一棘轮223以及第二棘轮224。具体地,第一棘轮223和第二棘轮224均与转轴222固定,其中第一棘轮223和第二棘轮224的齿轮开设方向相反,在第一棘轮223被锁定时,第二棘轮224呈释锁状态;在第二棘轮224被锁定时,第一棘轮223呈释锁状态。
如图4所示,安全带卷收器22上设有用于限制安全带在预定方向上的滚动的锁定件220,较佳地,该锁定件220包括第一锁定件225以及第二锁定件226。具体地,如图3-6所示,在转轴222之侧设置第一锁定件225,该第一锁定件225通过弹性件,如扭簧225a可摆动地安装在卷收器安装件221上。在一个实施例中,第一锁定件225呈片状,可由金属片形成,其一端形成有凸部2251以与第一棘轮223的凹部2231相啮合,另一端形成有配合面2252以与连动件23的端部的顶推平面231相抵接。可选择地,第一锁定件225在连动件的驱动下与第一棘轮223相啮合或脱离。在转轴222的另一侧,靠近第二棘轮224的位置处的卷收器安装件221上安装第二锁定件226,该第二锁定件226通过弹性件,如扭簧226a可摆动地装在卷收器安装件221,并在连动件23的推动下,可选择性地与第二棘轮224相啮合或脱离。具体地,第二锁定件226的中部通过枢轴安装在卷收器安装件221上,一端部与连动件23连接,另一端部与第二棘轮224相配合。
具体地,在小孩未就座于安全座椅,安全带扣具固定件21未被扣上(即扣具释锁)的情况下,安全带自动调整装置2的状态如图3所示。此时,安全带扣具固定件2朝向座椅前方,连动件23的末端与第一锁定件225紧贴抵顶,第一锁定件225与第一棘轮223呈脱离状态,如图4所示;第二锁定件225一端与连动件23连接,另一端与第二棘轮224啮合,此状态下,第二棘轮224的顺时针转动受限,逆时针转动不受限,同样地,第一棘轮223可随第二棘轮224逆时针转动。即,安全带卷收装置可逆时针转动,此时,被释放而可被任意拉出。当小孩就座时,安全带扣具固定件21被扣上,即,如3图所示,安全带扣具固定件被沿箭头方向推至如图5所示的位置,此过程中,连动件沿箭头方向向前推动,失去顶推力的第一锁定件225在扭簧225a的作用下向第一棘轮223的方向翻转,实现与第一棘轮223的啮合,与此同时,第二锁定件226被驱动远离第二棘轮224而脱离其啮合,如图6所示。在此状态下,第一棘轮223的逆时针转动受限,顺时针转动不受限;而第二棘轮224则可随第一棘轮223顺时针转动。即,安全带卷收器22可顺时针转动,此时安全带被自动卷收而将肩带拉紧,从而实现自动拉紧安全带。
综上所述,本发明的安全带自动调节装置2通过安全带扣具固定件21的状态改变来实现安全带卷收器22的自动锁定或释锁,从而自动锁定或释锁安全带,当小孩就坐扣上安全带扣具后,安全带可自动收紧,无需手动调整,结构简单、操作方便,且安全可靠,适于推广应用。
以上所揭露的仅为本发明的较佳实施例而已,当然不能以此来限定本发明之权利范围,因此依本发明申请专利范围所作的等同变化,仍属本发明所涵盖的范围。
