The invention discloses a vehicle, a vehicle seat backrest rigidity adjusting device and a control method. The device comprises a retractor, a driving assembly and at least one supporting belt. The driving assembly at least can drive the reel to rotate so as to wind part of the supporting belt on the reel when the vehicle has a head-on collision, and the supporting belt exerts certain acting force on the seat backrest while the supporting belt is partially stored on the reel, so that the seat backrest is integrally tensioned, the rigidity of the seat backrest is increased, and the service life of the seat backrest is prolonged. Especially when a vehicle has a frontal high-speed collision, the rigidity of the seat backrest is increased, so that the impact of heavy objects in the trunk on rear-row passengers due to inertia can be reduced, and the comfort of the rear-row passengers is improved.
本发明公开了一种车辆、车辆座椅靠背刚性调节装置及控制方法,该装置包括卷收器、驱动组件和至少一条支撑带;本文中的驱动组件至少能够在车辆发生正面碰撞时驱动卷轴转动以将部分支撑带收卷于卷轴,在支撑带部分收纳与卷轴上同时,支撑带也将施加一定的作用力于座椅靠背,进而将座椅靠背整体拉紧,增大座椅靠背的刚度,尤其对于车辆发生正面高速碰撞时,座椅靠背刚度增大可以减小行李箱中重物由于惯性对后排乘员产生的冲击,提高后排乘坐人员舒适性。
