Description

Helmet Technical Field The present invention relates to helmets, and more particularly to helmets that can remove liners associated with the interior of the helmet in emergency situations. Background For two-wheeled vehicles, there is a high risk of the impact being directly transferred to the passengers in the event of an accident. It is thus required that the passenger of the two-wheeled vehicle must wear a riding helmet, i.e., a helmet, for protecting the head. Generally, a helmet includes an outer shell that first protects a wearer's head from an external impact, and a pad coupled with an inner side of the outer shell. In this way, the pad provided in the outer case is closely attached to the head of the wearer to provide a wearing stability, and prevents the helmet from falling off easily when the helmet is worn. On the other hand, when an accident occurs and a user needs to be rescued, the helmet needs to be detached from the head of the user. However, the cushion closely attached to the head of the wearer causes difficulty in separating the helmet, and secondary injury occurs in the neck of the wearer during forced separation of the helmet. There is thus a current need to develop a helmet in which the pad is stably fixed to the inside of the helmet, providing a comfortable wearing feeling, and which can be easily removed in case of accident, in order to easily separate the helmet from the wearer's head. (Existing literature) korean patent No. 1995947, "helmet with removable liner for emergency", grant bulletin of 7/3/2019 Disclosure of Invention Technical problem The present invention has been made to solve the above-described problems of the prior art, and an object of the present invention is to provide a helmet that can effectively remove a pad disposed between an outer shell and a wearer's head in combination with an inside by a force having a specific direction, and can be easily separated from the wearer's head in an emergency. Solution to the problem According to one embodiment of the present invention, there is provided a helmet including a helmet body, a pad coupled to an inside of the helmet body, and a fastening unit configured to detachably couple the helmet body and the pad, wherein the fastening unit includes an outer fastening member disposed in one of the inside of the helmet body and the pad, and an inner fastening member disposed in the other of the inside of the helmet body and the pad, the outer fastening member having a first inclined surface at a portion inserted and fixed to the inner fastening member, the inner fastening member having a second inclined surface corresponding to the first inclined surface, and when the outer fastening member is coupled to the inner fastening member, an external force is applied to the pad in a first direction to separate the outer fastening member from the inner fastening member, the first inclined surface moves along the second inclined surface to separate the pad from the helmet body. In this case, the outer fastening member may include a base portion attached to one of the inside of the helmet body and the pad, an extension portion protruding from one surface of the base portion and having the first inclined surface on one side, and an expanded end portion at least a portion of which is expanded outward in a direction perpendicular to an extending direction of the extension portion and is provided at an end portion of the extension portion in the extending direction. The portion of the extension portion having the first inclined surface in the middle thereof may protrude further outward than the expansion end portion in a direction perpendicular to the extension direction. The helmet may further include a cover plate disposed to cover one surface of one of the pad and the inside of the helmet body, and the base portion may be attached to the cover plate. The cover plate may have a through hole formed in a size that prevents the base portion from passing therethrough, the base portion may be disposed inside the helmet body or between the pad and the cover plate, and the extension portion may extend through the through hole. The extending portion may include a first extending portion extending through the through hole, and a second extending portion disposed between the first extending portion and the expansion end portion, and having the first inclined surface on one side. The helmet may further include a fixing portion fixed to the cover plate, and a play preventing member including a play preventing portion connected to the fixing portion so as to be fastened to the extension portion to prevent play of the outer fastening member. The second extension portion may include a fastening portion for fastening the play preventing portion, and the play preventing portion may be fastened to the fastening portion. The inner fastening member may include a main body having a receiving space for receiving at least a part of the extension portion and the
