The invention relates to vehicle parts, and provides a seat, an unlocking device thereof and a vehicle. The seat comprises a cushion part (11), a backrest part (1) and a locking piece (8), the unlocking device comprises a telescopic arm assembly and a driving piece (9), and the driving piece (9) can be manually operated to drive the telescopic arm assembly to rotate between a first position and a second position. In the process that the telescopic arm assembly rotates from the first position to the second position, the length of the telescopic arm assembly is gradually increased, and the torque of the telescopic arm assembly acting on the locking piece (8) is gradually increased. According to the unlocking device of the seat, the telescopic arm assembly with the variable length can allow the torque acting on the locking piece to be increased under the condition that the applied acting force is basically unchanged, the characteristic that the unlocking acting force of the locking piece is gradually increased can be better adapted, the locking piece can be unlocked more easily, and the user experience is improved.

    本发明涉及车辆部件,提供一种座椅及其解锁装置以及车辆,其中,所述座椅包括坐垫部(11)、靠背部(1)以及锁定件(8),所述解锁装置包括伸缩臂组件、驱动件(9),所述驱动件(9)能够手动操作以驱动所述伸缩臂组件在第一位置和第二位置之间转动,在所述伸缩臂组件从所述第一位置转动所述第二位置的过程中,所述伸缩臂组件的长度逐渐增加,并且所述伸缩臂组件作用于所述锁定件(8)的扭矩逐渐增加。本发明所述的座椅的解锁装置中,长度可以变化的伸缩臂组件可以允许在施加的作用力基本不变化的情况下作用于锁定件的扭矩增加,可以更好地适应锁定件的解锁作用力逐渐增加的特性,可以更容易地使得锁定件解锁,提升了用户体验。
