Description

Wearable devices, systems, and methods of manufacture for neck protection Technical Field The present invention relates to a wearable safety device and a method of manufacturing the same, and more particularly, to an airbag device for neck protection of a human body, a method of manufacturing the same, and a control unit for the same. Background Automotive airbag devices have been implemented for many years as protection devices for drivers and passengers in the event of a traffic accident. However, motorcycle safety equipment is not provided with an airbag. On the other hand, motorcycles account for a large proportion of traffic accidents, and head and neck injuries in serious fatal car accidents related to the traffic accidents account for a large proportion. Although the helmet has a better protection effect on the head of the motorcycle user, the helmet cannot effectively protect the neck of the motorcycle user, and a safety blind spot which is easy to ignore is formed. Disclosure of Invention The invention is used for an airbag for providing protection for the neck, so as to improve the safety of motorcycle users. The wearable safety devices described herein include a helmet and a protective airbag mounted to a bottom edge of the helmet, and a corresponding control device. In the event of an accident, for example when driving a motorcycle in a collision with another object, the air-bag is activated to inflate, forming a cushion air-bag around the neck portion of the motorcycle user. The air bag is inflated instantaneously after an accident and can be separated from the helmet to independently encircle the neck of a user, the air bag surrounds the neck of the user and is supported on the shoulders, the front chest and the lower edge of the helmet, and the inflated air bag protects the head and neck of the motorcycle user before the motorcycle user falls down or is thrown out of the motorcycle to strike surrounding objects, so that the injury degree is greatly reduced. The wearable safety device comprises a helmet and an openable soft air bag bin arranged on the inner side of the bottom edge of the helmet, and an air bag is folded and stored in the air bag bin. An electronic control unit is arranged along the outer side of the lower edge of the bottom of the helmet and comprises a sensor, an integrated circuit board, a controller, a battery, an air source, an air pipe and the like. The space required by the air bag bin can be manufactured by changing the soft lining of the helmet on the premise of not changing the rigid shell of the existing helmet. When an accident occurs and a motorcycle user collides with an object, the sensor detects the change of the movement condition of the motorcycle user through the acquired measurement data and evaluates the damage degree to the neck. The data is transmitted to the controller to determine if a predetermined threshold is reached, and if so, the bladder is activated and inflated to form a cushion bladder loop that closely surrounds the neck portion of the motorcycle user. The air bag can be rapidly inflated at the moment of accident, for example, within one hundredth of a second after the accident, so that the neck of the motorcycle user is protected before the accident hurts the motorcycle user, and the fatal injury to personnel is greatly reduced. According to one aspect, the invention provides a wearable device for neck protection, comprising an air bladder made of flexible and airtight material webs comprising a first main web and a second main web, each having a partially annular main body portion, an outer peripheral edge, an inner peripheral edge, a first end portion, a second end portion, and an airway portion, the outer peripheral edge of the first main web being in airtight engagement with the outer peripheral edge of the second main web, the inner peripheral edge of the first main web being in airtight engagement with the inner peripheral edge of the second main web, the first end portion of the first main web being in airtight engagement with the first end portion of the second main web, the second end portion of the first main web being in airtight engagement with the second end portion of the second main web, the airway portion of the first main web being in airtight engagement with the airway portion of the second main web constituting an air inlet. The airbag is deformable from a folded state in which a main body portion of the first main panel is in contact with the main body portion of the second main panel to an inflated state in which the main body portion of the first main panel is separated from the main body portion of the second main panel to constitute a gas accommodating space therebetween. Optionally, the air channel portion includes a first air channel portion, a second air channel portion and a third air channel portion, the first air channel portion is located in a middle portion of a main body portion of the first main material shee
