The invention discloses a safety belt pre-tightening device and a vehicle and relates to the technical field of vehicle engineering. The pre-tightening device comprises a pre-tightening plate and a gas generator, wherein the pre-tightening plate is movably arranged on a stand column inner plate of a vehicle body, an inserting block mechanism is arranged between the pre-tightening plate and an inner side wall of the stand column inner plate, the inserting block mechanism comprises a moving part arranged on the pre-tightening plate and a fixed part arranged on the stand column inner plate, the moving part and the fixed part are in pluggable fit, the gas generator is fixed to the stand column inner plate and electrically connected with an airbag controller, an end of a movable push rod of thegas generator is connected with the pre-tightening plate, and the pre-tightening plate can be driven to move in the direction close to the stand column inner plate. The pre-tightening device is advantaged in that the pre-tightening plate is driven to move through the gas generator while the air bag is started, a safety belt braid is pressed between the movable part and the fixed part which are matched in an inserted and pulled mode, pre-tightening of the safety belt is achieved, and a driver and passengers are protected against injuries of the air bag.
本发明公开了一种安全带预紧装置及车辆,涉及车辆工程技术领域,包括:预紧板,可移动地设置在车身的立柱内板上,预紧板与立柱内板的内侧壁之间设置有插块机构,插块机构包括设置于预紧板上的移动部和设置于立柱内板上的固定部,移动部与固定部形成插拔式配合;气体发生器,固定在立柱内板上,与气囊控制器电性连接,气体发生器的活动推杆端部与预紧板相连接,能够带动预紧板向靠近立柱内板的方向移动;该预紧装置在气囊启动的同时通过气体发生器带动预紧板移动,将安全带织带压入插拔配合的移动部和固定部之间,实现安全带的预紧,保护司机和乘客不受气囊的伤害。
