Vehicle device, vehicle collision protection seat and acceleration and deceleration protection safety belt device

Abstract

The invention discloses a vehicle device, a vehicle collision protection seat and an acceleration and deceleration protection safety belt device.The vehicle device comprises a cushion, fixed rotating shafts are fixedly arranged on the front side and the rear side, close to the left end face, of the cushion, lacing belts are fixedly arranged on the fixed rotating shafts, and the cushion is bound to the vehicle seat through the lacing belts; a sleeve is rotatably arranged on the fixed rotating shaft, a connecting seat is fixedly arranged on the sleeve, a backrest supporting frame used for supporting is fixedly arranged on the connecting seat, a soft backrest is fixedly arranged on the right side end face of the backrest supporting frame, and notches are formed in the front side and the rear side of the cushion correspondingly. And a blocking cylinder is arranged outside the cushion. According to the utility model, the requirements of comfort and natural activity of the pregnant woman in the riding process can be met; the vehicle protection seat and the vehicle collision protection and acceleration and deceleration protection device are used for protecting a passenger and reducing the extrusion of a vehicle safety belt on the abdomen of the pregnant passenger in a mode of decomposing inertia buffering.

Description

technical field [0001] The invention relates to the technical field of vehicle seats and vehicle engineering, in particular to a vehicle device, a vehicle collision protection seat and a safety belt device for acceleration and deceleration protection. Background technique [0002] As the basic protective device for protecting drivers and passengers during a car collision, the seat belt was born earlier than the car. As early as 1885, seat belts appeared and were used on carriages to prevent passengers from falling from the carriage. In a car race held in New York on May 20, 1902, a racer tied himself and his companion to the seat with several belts in order to prevent being thrown out of the car at high speed. During the race, the car they were driving crashed into the crowd of spectators by accident, killing two people and injuring dozens of others. However, these racers narrowly escaped death because of the belt. These belts have become the embryonic form of car seat bel...

Problems solved by technology

[0003] Nowadays, the most mainstream seat belt is the three-point seat belt, which protects the human body from the inertia caused by the emergency braking of the vehicle by restraining the chest and abdomen of the human body. In daily use, the seat belt does protect many people, but according to Studies have shown that many female passengers are reluctant to wear seat belts during pregnancy due to comfort and to prevent harm to the fetus due to the compression of the seat belt on the abdomen. The fatality rate is 3.5%, otherwise it is 25%. When there is no traffic accident, because emergency braking will also cause the impact of extrusion on the fetus, this example aims to design a car that can meet the needs of the baby when riding a car. Under the requirements of the comfort and natural mobility of pregnant women when riding in the car, the vehicle protection seat, vehicle collision protection and acceleration and deceleration protection are used to protect passengers by decomposing inertial cushioning and reducing the pressure of vehicle seat belts on the abdomen of pregnant passengers device
