The invention provides a pre-tightening force limiting safety belt, which belongs to the technical field of automobile safety belts. The problem that an existing safety belt cannot provide matched pre-tightening force for passengers with different body types is solved. The pre-tightening force limiting safety belt comprises a controller, a pre-tightening motor, a reel and a braid wound on the reel, the controller can control the pre-tightening motor to work, the pre-tightening motor can drive the reel to rotate, and the pre-tightening force limiting safety belt further comprises a gravity sensor capable of detecting the weight of a passenger, the gravity sensor can transmit a detected passenger body weight signal to the controller, and the controller can control the pre-tightening motor to drive the reel to rotate by a certain number of turns according to the received passenger body weight signal so that the braid can provide pre-tightening force matched with the body weight of a passenger. The pre-tightening force limiting safety belt not only ensures the riding safety of passengers, but also ensures the riding comfort of the passengers.

    本发明提供了一种预紧限力安全带,属于汽车安全带技术领域。它解决了现有的安全带无法对不同体型乘客提供相匹配的预紧力的问题。本预紧限力安全带,包括控制器、预紧电机、卷轴和缠绕在卷轴上的织带,控制器能够控制预紧电机工作,预紧电机能够驱动卷轴转动,本预紧限力安全带还包括能够检测乘员体重的重力传感器,重力传感器能够将检测到的乘员体重信号输送给控制器,控制器能够根据接收到的乘员体重信号来控制预紧电机驱动卷轴转动一定的圈数使得织带提供与该乘员的体重相匹配的预紧力。本预紧限力安全带既保证了乘员的乘坐安全性,又保证了乘员的乘坐舒适性。
