AIRBAG DEVICE AND PASSENGER PROTECTING DEVICE - A simplified explanation of the abstract

This abstract first appeared for US patent application 18378715 titled 'AIRBAG DEVICE AND PASSENGER PROTECTING DEVICE

Simplified Explanation

The patent application describes an airbag device with a unique design to protect passengers in a vehicle. Here are the key points of the innovation:

  • The airbag device includes an airbag with a front-rear chamber and an airbag main body.
  • The front-rear chamber has left and right front-rear extending portions that inflate towards the seat front side, passing by the passenger's head.
  • A connecting portion links the front end portions of the extending portions in a seat left-right direction.
  • The airbag main body inflates towards the passenger's side at the seat rear side, after the front-rear chamber inflates.
  • When the passenger is restrained, the airbag main body compresses in a seat front-rear direction while stretching the front-rear chamber in the seat front-rear direction.
      1. Potential Applications

This technology can be applied in various vehicles to enhance passenger safety during collisions or accidents.

      1. Problems Solved

This innovation addresses the issue of providing effective protection to passengers in vehicles by deploying airbags in a strategic manner.

      1. Benefits

The airbag device offers improved safety measures for passengers by deploying airbags in a sequence that maximizes protection.

      1. Potential Commercial Applications

This technology can be utilized by automotive manufacturers to enhance the safety features of their vehicles, potentially increasing consumer interest and trust.

      1. Possible Prior Art

One possible prior art could be the traditional airbag systems that deploy in a single direction without the unique front-rear chamber design described in this patent application.

        1. Unanswered Questions
        1. How does the airbag device determine the appropriate timing for deploying the airbag main body after the front-rear chamber?

The patent application does not provide specific details on the mechanism or sensors used to determine the timing of deploying the airbag main body.

        1. Are there any limitations to the design of the airbag device that could impact its effectiveness in certain types of collisions?

The patent application does not mention any potential limitations or scenarios where the airbag device may not provide optimal protection for passengers.


Original Abstract Submitted

An airbag device has an airbag. The airbag has a front-rear chamber and an airbag main body. The front-rear chamber has a left and right pair of front-rear extending portions that pass by respective left and right sides of a head of a passenger seated in a vehicle seat and inflate and deploy toward the seat front side, and a connecting portion connecting front end portions of the pair of front-rear extending portions in a seat left-right direction. The airbag main body inflates and deploys toward a side of the passenger at a seat rear side of the connecting portion, later than the front-rear chamber. At a time when the passenger is restrained, the airbag main body is compressed in a seat front-rear direction while stretching the front-rear chamber in the seat front-rear direction.
