Description

Vehicle safety belt propelling movement reminding device

Technical Field

The invention relates to the technical field of vehicle safety, in particular to a vehicle safety belt pushing reminding device.

Background

Safety belts are a very critical component of vehicle safety systems. During normal high-speed running of the vehicle, the sitting posture of the passenger can shake due to the change of traffic and road conditions, such as braking and turning, or acceleration generated by the change of the road surface. Without the seatbelt restraint, the occupant may collide with the vehicle interior components when the acceleration is large. In extreme cases, such as a vehicle crash, the occupant may be thrown out of the vehicle due to extreme acceleration if there is no seatbelt restraint. When the air bag is ejected and unfolded, the body of a passenger moves forwards due to acceleration, the passenger is contacted with the air bag which is not completely unfolded, and the passenger is subjected to more serious injury due to overlapping impact. Therefore, when riding a high-speed vehicle, it is necessary to fasten a seat belt.

Currently, most of the vehicle occupants, such as the driver and the passenger seat, are equipped with a seatbelt apparatus, which includes: the safety belt, the safety belt lock catch, the reminding module and the like. When the passenger thinks that the restraint of the safety belt is uncomfortable due to insufficient safety consciousness, the passenger may choose not to fasten the safety belt, and the reminding module gives out a reminding sound when the passenger is detected to be seated on the seat but the safety belt is not fastened.

Most of conventional vehicles can generate a warning sound when a passenger or a driver does not fasten a seat belt after the vehicle is started, but the warning sound is low in volume and is not easy to be perceived, so that the passenger or the driver can easily drive the vehicle without fastening the seat belt. Because the safety belt is arranged at the inner sides of the B column and the C column of the vehicle and extends out of the outlet, after a passenger or a driver finds that the passenger or the driver needs to turn the upper half body to take the safety belt lock catch, the safety belt fastening operation is complicated, and the safety belt fastening operation is inconvenient and inconvenient.
