Description

Convertible passenger protection system and vehicle Technical Field The utility model relates to the technical field of automobile safety, in particular to a convertible passenger protection system and a convertible passenger protection vehicle. Background The convertible car is a car with a folding openable roof, and because the car does not have a traditional car roof, a corresponding rolling frame is usually arranged on the car to form a convertible car passenger protection system, and a supporting space is formed above passengers. In order to ensure safe driving of an automobile and ensure safety of personnel in the automobile, the prior automobile is basically provided with an air bag in a seat, wherein the air bag in the seat is usually a side air bag, and the two sides of a front and back driving seat are close to the position of a B column. However, in terms of the vehicle body structure, the convertible vehicle has a certain safety hazard, and if the convertible vehicle turns over at a high speed, the probability of injury of passengers is far higher than that of a closed passenger vehicle. During a roll over of the vehicle, the occupant is not restrained in the seat, thereby increasing the chance of injury to the occupant. In order to make the automobile more attractive and comfortable, a sheath is usually additionally arranged on a seat and a headrest, but the explosion opening of the safety air bag is blocked, so that the safety air bag cannot be sprung open, and the safety air bag cannot play a role in protection in time. Accordingly, there is a need for a convertible occupant protection system and a vehicle that address the above-described issues. Disclosure of utility model The utility model aims to provide a convertible vehicle passenger protection system, an anti-rolling frame ejects out of a headrest and breaks a headrest sheath, then an air bag ejects out of the anti-rolling frame forwards, and the inflated air bag is positioned above the top of the head of a passenger, so that the top of the head of the passenger is effectively protected.
