Embodiment 1

[0022] exist figure 1 In the shown embodiment 1, a kind of rear impact protection air bag device is arranged on the seat of the car, and the air bag device includes an inflatable air bag 1 for constraining the driver and passengers by inflating and expanding and for The inflatable airbag provides the gas generator 2 of gas, the inflatable airbag and the gas generator are all arranged on the top of the seat 4, the safety airbag device also includes a collision sensor and a controller 5, and the collision sensor is arranged at the rear of the automobile , the controller is connected to the collision sensor 6 and the gas generator; when the car has a rear collision, the collision sensor sends a collision signal to the controller, and the controller turns on the gas generator to inflate the inflatable airbag through the air pipe 3, and the inflatable airbag pops up and expands , the inflated airbag after deployment is located between the head 7, neck 8 of the driver and passenger,...

Embodiment 2

[0024] The inflatable airbag and the gas generator of embodiment 2 are all arranged on the lower part of the headrest. When the inflatable airbag pops up, the main body of the inflatable airbag is located at the junction of the seat back and the headrest; The left and right ends of the seat extend to the front of the seat and constitute the blocking portion 13 that restrains the driver and occupant's head both sides (see Figure 4 ); the rest are the same as in Example 1.

Embodiment 3

[0026] The airbag device of embodiment 3 also includes a distance-measuring radar and an alarm device, and the distance-measuring radar includes a forward radar 14 arranged at the front of the automobile and a rearward radar 15 arranged at the rear of the automobile (see figure 2 ), the forward radar and the backward radar are both connected to the controller; the alarm device includes a sound alarm device 16 and a light alarm device 17, the alarm device is connected to the controller, and the controller is connected to the automobile ECU (automobile driving computer); the rest are identical to embodiment 1 or embodiment 2.

[0027] In the control method of the rear collision protection airbag device of embodiment 3, the forward radar and the backward radar are respectively used to measure the real-time distances between the vehicle and the vehicle in front and between the vehicle and the rear vehicle, and the controller receives the distance between the vehicle and the vehicle ...

Abstract

The invention discloses a rear collision protection safety airbag device and method. The rear collision protection safety airbag device comprises an inflatable airbag and an air generator. The inflatable airbag and the air generator are arranged on the upper part of a seat, and the air generator and a collision senor arranged on the tail part of a car are connected with a controller. When the carappears rear collision, the controller turns on the air generator to inflate the inflatable airbag, and the spread inflatable airbag is located between the head and neck of a driver and passenger anda headrest and the upper part of a backrest of the seat. The rear collision protection safety airbag device and method can effectively solve the safety problem of the passenger in the rear collision of the car and effectively protect the head and neck of the driver and passenger, and high practical value is achieved.

Description

technical field [0001] The invention relates to the technical field of automobile safety, in particular to a rear-collision protection airbag device and method capable of avoiding automobile rear-end collision damage to the greatest extent. Background technique [0002] Automobiles in the prior art are not equipped with airbags for rear collision occupant protection, the torso of the driver and occupant is supported by the seat back and the occupant's head is in conflict with the seat headrest. However, the heads of most drivers and occupants do not completely touch the headrest of the seat when they are seated. When the car is rear-ended, the driver and occupant will move relative to the seat to the rear of the car due to inertia, and the torso will directly squeeze the seat. If the backrest of the chair is used, the head will first move backwards relative to the seat until it touches the headrest and then squeezes the headrest. At this time, the head moves a large amount r...
