Description

Rear seat passenger air bag

The present invention relates to an airbag for protecting passengers in the event of a collision of a vehicle, and more particularly to a rear seat passenger airbag installed in the seatback of the front seat so as to protect passengers in the rear seat. .

An air bag is a device that protects passengers by inflating the bag in the event of a car crash before the passengers cause a second crash.

The airbag consists of a collision sensor and diagnostic circuit for detecting a collision and an airbag module. The collision sensor and diagnostic circuit is mainly attached to the vehicle body. In the case of the airbag module, the driver's seat is mounted on a steering wheel. The passenger seat is divided into a downward installation type which is stored in the lower part of the instrument panel, an upward installation type in which the module is mounted almost horizontally rearward on the upper part of the instrument panel, and an upward installation type in which the module is installed on the upper surface of the instrument panel and the deployment direction of the bag is inclined upward. .

In this way, the collision sensor detects the collision during the collision of the vehicle, the diagnostic circuit determines the deployment of the bag by diagnosing the size and type of the collision detected by the collision sensor. If it is determined that the bag is to be deployed in the diagnostic circuit, the diagnostic circuit signals the air bag module to deploy the bag and thus protects the occupant by preventing the bag from being deployed in the air bag module to cause a secondary collision. .

However, in the related art, since the air bag as described above has been applied only to the driver's seat and the passenger seat, there has been a problem that there is no consideration of passengers of the rear seat. That is, since the airbag is not provided to the rear seat passengers, there is a serious problem of the injuries of the occupants on the rear seats when the car crashes.

Accordingly, the present invention has been made to solve the above problems, the object of the present invention is to provide a rear seat occupant airbag installed on the back of the seat back of the front seat to protect the rear seat occupant in the event of a car collision have.

1 is a perspective view showing a rear seat passenger air bag installed in the seat back of the front seat according to the present invention.

* Description of the symbols for the main parts of the drawings *

1: Air bag module 2: Front seat

2a: Seat back 3: Rear seat

The above object is composed of a collision sensor, a diagnostic circuit and an air bag module, the air bag for protecting the passenger by preventing the secondary collision of the passenger by the deployment of the bag during the collision of the vehicle, the seat back of the front seat It is achieved by the rear seat occupant airbag according to the present invention, characterized in that it is installed to be able to protect the passengers in the rear seat in the event of a vehicle crash.

Here, the collision sensor and the diagnostic circuit is preferably used in common with the driver's seat and the passenger seat air bag.

In addition, it is preferable that an operation switch is provided to determine whether to operate the bag so that the bag is not deployed when there are no passengers in the rear seat.

{Example}

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 shows a rear seat occupant airbag in accordance with the present invention.

The rear seat occupant airbag according to the present invention is composed of a collision sensor (not shown), a diagnostic circuit (not shown), and an airbag module 1 like the conventional driver's and passenger's airbags, and as shown, The air bag module 1 is installed on the back of the seat back 2a of the seat 2.

Here, the collision sensor and the diagnostic circuit are used in common with the driver's seat and the passenger seat airbag (not shown), and the operation switch (not shown) so that the airbag does not operate when there is no passenger in the rear seat 3 on the instrument panel. Is installed.

In the rear seat passenger air bag according to the present invention configured as described above, the bag is deployed from the rear of the seat back (2a) of the front seat (2) during the collision of the car, so that the passengers on the rear seat (3) collide secondary It is possible to protect the passengers in the rear seat (3) by preventing the occurrence of. In addition, when a passenger does not board the rear seat 3, the airbag module 1 installed at the rear of the seat back 2a of the front seat 2 may be operated by operating a switch installed in the instrument panel.

The present invention as described above, the air bag module is installed on the back of the seat back of the front seat, there is an advantage that can safely protect the occupants in the rear seat during the collision of the vehicle.

Claims (3)
