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 a two-wheeled vehicle occupant, and more particularly, to a backpack-type airbag device for a two-wheeled vehicle occupant that can safely protect the two-wheeled vehicle occupant from external impact and collision in the event of a motorcycle accident, and that the two-wheeled vehicle occupant can use easily and conveniently. It is about an airbag device.

In general, a two-wheeled vehicle refers to a vehicle having two wheels, but recently refers to a means of transportation having two front and rear wheels regardless of the presence or absence of an engine. For example, representative two-wheeled vehicles include bicycles and motorcycles.

In particular, the use of bicycles has recently been further expanded due to the increasing interest in physical training and health promotion, increased interest in leisure sports, and the expansion of the need for transportation that does not cause air pollution.

However, it is known that a rider of a two-wheeled vehicle is at higher risk of injury and death due to an accident than a rider of a vehicle. In other words, because motorcycle occupants are directly exposed to external shock or collision in the event of a motorcycle accident due to the structure and riding type of the motorcycle, the degree of injury and mortality rate of motorcycle occupants is comparable to vehicles that prevent or buffer external shock or collision in various ways. It has to be very high.

Therefore, the number of deaths of cyclists 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 due to air accidents.

In fact, in 2018 alone, 7,618 traffic accidents involving bicycles occurred in Korea, resulting in 121 deaths and 7,773 injuries. 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. Looking at these statistics alone, it can be seen 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 distribution rate and use of bicycles increase.

On the other hand, automobiles are provided with various safety devices to protect the safety of occupants from traffic accidents. For example, automobiles are equipped with seat belts and airbag devices.

In contrast, two-wheeled vehicles including bicycles have limitations or are impossible to install safety devices such as seat belts and airbag devices due to structural problems. Therefore, it is very important for riders of motorcycles to wear helmets or protective clothing for safety.

The main cause of death related to two-wheeled vehicles is head injury, which frequently occurs in traffic accidents involving bicycles and motorcycles. Therefore, a helmet is the best way to reduce the possibility of head injury in the event of a motorcycle crash. However, despite the encouragement and warnings for helmet use, the helmet utilization rate is still low, especially among cyclists.

Because the types of bicycle use are very diverse, the types of accidents are also very diverse. For example, bicycles are used in various forms according to various purposes such as commuting, leisure, sports, etc., or are used in various forms depending on the type of road, places such as mountains, and the age and gender of passengers.

Recently, clothing to which an airbag device is applied has been developed in order to secure the safety of the occupant of the two-wheeled vehicle. That is, the safety clothing for the occupants of the two-wheeled vehicle is manufactured in the same shape as the normal clothing, but has a structure in which an airbag device is disposed in an important part of the safety clothing. Therefore, in the event of an accident of a two-wheeled vehicle, an airbag device installed in a safety suit of a passenger operates to protect important parts of the occupant with the airbag.

However, the existing safety clothing equipped with an airbag device is too large in weight and size, so the fit and ease of use are poor, and due to the structure of the safety clothing, it is more inconvenient to move than everyday clothes or sportswear, and it is prepared in advance as a clothing for wearing the safety clothing. There is a problem that needs to be addressed. In particular, since the existing safety clothing equipped with an airbag device must be prepared individually according to the body shape of the motorcycle occupant, motorcycle occupants of various body types must individually purchase in advance, and additionally various types must be provided according to hot or cold weather. There are also problems with

Therefore, there is an urgent need for a safety device for two-wheeled vehicle occupants with high usability and usability while safely protecting the occupant of the two-wheeled vehicle from external impact and collision when an accident occurs.
