Description

Backpack-type airbag device for two-wheeled vehicle occupants {BACKPACK TYPE AIR-BAG APPARATUS FOR BICYCLE OCCUPANT}

The present invention relates to a backpack-type airbag device for two-wheeled vehicle occupants, and more specifically, to a two-wheeled vehicle rider's backpack-type airbag device that can safely protect two-wheeled vehicle occupants from external shocks and collisions in the event of a two-wheeled vehicle accident, and can be easily and conveniently used by two-wheeled vehicle occupants. It is about airbag devices.
This invention is the result of research conducted as a 2020 technology holding company subsidiary R&BD support project supported by the Korea Institute for Advancement of Technology. (Project number: S2911219, Research project name: Technology Holding Co., Ltd. subsidiary R&BD)

Generally, a two-wheeled vehicle refers to a vehicle with two wheels, but recently, it refers to a means of transportation with two wheels front and back, regardless of whether there is an engine or not. For example, representative two-wheeled vehicles include bicycles and motorcycles.

In particular, the use of bicycles has recently been expanding due to the growing interest in leisure sports as a means of physical training and health promotion, and the growing need for transportation that does not cause air pollution.

However, it is known that riders of two-wheeled vehicles have a higher risk of injury and death due to accidents than those of automobiles. In other words, riders of two-wheeled vehicles are directly exposed to external shocks or collisions in the event of a motorcycle accident due to the structure and riding type of the two-wheeled vehicle, so compared to cars that prevent or buffer external shocks or collisions in various ways, the degree of injury and death rate of two-wheeled vehicle riders This has to be very high.

Therefore, the number of deaths of bicycle riders due to collisions with automobiles is comparable to the number of deaths due to railway or marine accidents, and is more than twice the number of deaths in air accidents.

In fact, in 2018 alone, there were 7,618 traffic accidents involving bicycles in Korea, and 121 people died and 7,773 were injured in these accidents. Therefore, the number of deaths per 100 accidents is 1.6, which is more than three times higher than the 0.5 deaths in passenger cars. Just looking at these statistics, you can see that bicycles are a more dangerous means of transportation than cars in Korea. In addition, the number of deaths due to bicycle traffic accidents is gradually increasing as the penetration rate and use of bicycles increases.

Meanwhile, cars are equipped with various safety devices to protect the safety of occupants from traffic accidents. For example, cars are equipped with seat belts and airbag devices.

On the other hand, due to structural problems, it is limited or impossible to install safety devices such as seat belts and airbag devices on two-wheeled vehicles, including bicycles. Therefore, it is very important for motorcycle riders to wear helmets or protective clothing for safety.

The main cause of death related to two-wheeled vehicles as described above is head injuries, which frequently occur in traffic accidents involving bicycles and motorcycles. Therefore, a helmet is the best way to reduce the likelihood of head injury in the event of a two-wheeler collision. However, despite encouragement and warnings to use helmets, the helmet utilization rate is still low, especially among bicycle riders.

Because there are so many different types of bicycle use, there are many different types of accidents. For example, bicycles are used in various forms according to various purposes such as commuting to work, leisure, sports, etc., or are used in various forms depending on the type of road, location such as a mountain, and the age and gender of the passenger.

Recently, clothing equipped with an airbag device has been developed to ensure the safety of two-wheeled vehicle occupants. In other words, safety clothing for two-wheeled vehicle riders is manufactured in the same shape as regular clothing, but has an airbag device placed in important parts of the safety clothing. Therefore, in the event of a two-wheeled vehicle accident, the airbag device installed in the occupant's safety suit operates to protect the occupant's important parts with the airbag.

However, the safety clothing equipped with the existing airbag device is too large in weight and size, making it less comfortable to wear and use. Due to the structure of the safety clothing, it is more uncomfortable to move than everyday clothes or sportswear, and it is prepared in advance as clothing to wear the safety clothing. There is a problem that needs to be addressed. In particular, safety clothing equipped with existing airbag devices must be prepared individually according to the body type of the two-wheeled vehicle rider, so motorcycle riders of various body types must personally purchase them in advance, and additionally various types must be provided depending on hot or cold weather. There is also a problem.

Therefore, when a two-wheeled vehicle accident occurs, there is an urgent need for a safety device for two-wheeled vehicle occupants that safely protects the rider of the two-wheeled vehicle from external shocks and collisions while providing high usability and ease of use.
