Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a helmet hooking structure for a motorcycle or a scooter type motorcycle, and more particularly, to a hook protruding from a vehicle body and an openable and closable attachment to the vehicle body. It is related to the structure that locks the helmet so that it will not come off.

[Conventional technology]

2. Description of the Related Art Conventionally, motorcycles and three-wheeled vehicles have adopted a helmet retaining structure for retaining the helmet so as not to come off when getting off the vehicle and preventing the helmet from being stolen. As a first conventional example of such a helmet hooking structure, the hook of the helmet is engaged with a hook protruding from the upper surface of the vehicle body, and the seat is locked in this state to prevent the helmet from coming off. (For example, the actual public Sho 49
-38850 and 58-41682. Further, as a second conventional example, there is one in which a hook is provided so as to project from the upper surface of the vehicle body and an insertion concave portion into which the hook is inserted when the seat is closed is formed on the bottom plate of the seat (see Japanese Utility Model Publication No. 49-38851).

[Problems to be solved by the invention]

However, the hook is generally made of resin, and cannot be so large because of the structure for locking the latch, and therefore the rigidity cannot be so great. Therefore, in the above-mentioned first conventional example, there is a problem that the hook easily bends against external force, and as a result, the helmet is easily removed by pushing and bending the hook from the outside. On the other hand, in the second conventional example, if the insertion length into the insertion recess is made longer, the hook is less likely to bend, and the helmet can be held securely. However, in the second conventional example, the substantial thickness of the insertion recessed portion of the seat is reduced by the lengthening of the insertion length, which causes a problem of impairing cushioning properties.

The present invention has been made to solve such a conventional problem, and the hook length is short, the helmet can be reliably prevented from coming off, and the cushioning property of the seat is not impaired. ， The purpose is to provide a helmet hooking structure for a tricycle.

[Means for solving problems]

The present invention relates to a helmet hooking structure for a motorcycle, in which a seat having a flange portion bent downwardly around a bottom plate is openably opened and closed by a hinge at a front end portion. In the vicinity of the rear side of the hinge, a hook for hooking the helmet is provided so as to extend upward in a substantially straight line, near the boundary between the bottom plate and the flange portion of the seat, and the hook when the seat is closed. A hook receiving portion that engages is formed, and the hook receiving portion has a substantially tubular shape including a main body portion protruding downward from the vicinity of the boundary and a part of the flange portion, and an upper end portion of the hook when the seat is closed. It is characterized by having a shape that substantially surrounds the circumference of.

[Action]

According to the helmet hooking structure for a motorcycle according to the present invention, the hook is extended substantially linearly upward, and the hook receiving portion, the main body portion integrally formed with the flange portion, and one of the flange portion Since the upper part of the hook enters into the hook receiving part when the seat is closed, the hook is short and the bending strength of the hook itself is improved, and the hook has a cylindrical shape. Since it is hard to come off from the hook receiving part, the hooking force of the helmet can be greatly improved and theft can be prevented. Further, since the hook receiving portion is formed into a substantially cylindrical shape by utilizing a part of the flange portion, the hook receiving portion can be made compact. Furthermore, the substantial thickness of the seat is substantially the same in the seat receiving portion and other portions, and the cushioning property of the seat is not significantly impaired.
