The invention discloses a fabric belt type brake automobile seat with a torsion spring. The automobile seat comprises an upper track assembly, a lower track assembly, a scissor arm assembly, a gas spring, a control part and a winding mechanism, wherein the upper track assembly and the lower track assembly are respectively connected to the upper and lower ends of the scissor arm assembly, and the upper track assembly and the lower track assembly are similar in structure; and the upper track assembly comprises two symmetrically-arranged upper U-shaped tracks and a first connecting plate locatedat the ends of the two upper U-shaped tracks. The automobile seat has the beneficial effects that when the seat vibrates upwards by 40 mm from a balance position, gas for a control valve is disconnected, the winding mechanism is locked, and then the seat slowly drops to the balance position; and when a driver gets up, an air bag pushes the seat to move upwards by 40 mm, gas for the control valve is disconnected, the winding mechanism is locked, and then the seat slowly drops to the balance position. The torsion spring of the seat is used for reducing the impact caused by the fabric belt contraction on a power device when the seat rises.
本发明公开了一种带有扭簧的织带制动汽车座椅,包括上轨道组件、下轨道组件和剪式臂组件、气弹簧、控制部件和卷收机构;所述上轨道组件和下轨道组件分别连接在剪式臂组件的上下两端,上轨道组件和下轨道组件组件结构类似,其中上轨道组件包括两条对称设置的上U型轨道和位于两条上U型轨道端部的第一连接板;本发明的有益效果是:当座椅处于平衡位置向上震动行程40mm时,控制阀断气,卷收机构锁止,之后座椅缓慢下降到平衡位置;当驾驶员起身时,气囊推动座椅向上行程40mm时,控制阀断气,卷收机构锁止,之后座椅缓慢下降到平衡位置;本发明的扭簧用于减少座椅上升时织带收缩对动力装置的冲击。
