The invention provides a comfortable safety belt winder which is characterized in that a barrel shaft at one end of a belt winding barrel extends into a spring box cover, and a driving flat spiral spring and an auxiliary spring are axially arranged close to the shaft end of the barrel shaft in the spring box at an interval; in the process of pulling the safety belt, the middle-rear section driving flat spiral spring and the auxiliary spring provide elastic force to drive the safety belt to move in opposite directions. The auxiliary spring is additionally arranged, and the elastic force direction provided by the auxiliary spring is consistent with the force application direction of pulling the safety belt by hands, so that the effect of assisting in pulling the safety belt is achieved; therefore, the labor-consuming feeling that a user needs to exert more effort along with the longer pull-out length of the safety belt due to the elastic force which is purely provided by the active flat spiral spring and used for retracting and rolling the safety belt is improved, and the comfort of pulling the safety belt is improved.

    本发明提供一种舒适性安全带收卷器,卷带筒的一端筒轴延伸至弹簧盒盖内,位于弹簧盒内的筒轴轴端轴向临近间隔布置主动平面涡卷弹簧、助力弹簧,抽拉安全带过程的中后段主动平面涡卷弹簧、助力弹簧提供弹力驱使安全带的移动方向相反。本发明增设了助力弹簧,助力弹簧提供的弹力方向与人手抽拉安全带的施力方向一致,起到了助力抽拉安全带的作用,从而改善了主动平面涡卷弹簧单纯提供的回缩收卷安全带的弹力随着安全带拉出长度越长使用者就需要越用力的费力感受,从而提高了抽拉安全带的舒适感。
