DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a helmet of the full face type, and more particularly to a helmet for detachably attaching a cheek pad which is in contact with a cheek portion of a wearer.

[0002]

2. Description of the Related Art Conventionally, a full face type helmet has
For example, as proposed in Japanese Patent Publication No. 5-19293, a shock absorbing liner made of styrene foam or the like is fitted on the inner surface of the shell, and a cushion material made of sponge or the like is provided inside the shock absorbing liner to improve air permeability. It is configured with an interior pad covered with a highly elastic front cover. Also, in this type of full face type helmet, of the interior pads attached to the inside of the shock absorbing liner, the left and right cheek pads abutting on the wearer's cheek are divided and detachably attached to the shock absorbing liner. There is also known a full-face type helmet in which the cheek pad can be easily removed when the cheek pad is washed or the fitting is adjusted.
Japanese Patent Publication No. 4-61082 is known as such a full-face type helmet with a detachable cheek pad. As shown in FIG. 9, as shown in FIG. 9, a concave portion 3 for attaching the cheek pad 2 is formed on the inner surface of the shell 1, and a tongue piece 4 and a convex member 5 are formed on both ends of the cheek pad 2. An elastic body 6 that is elastically deformed in the horizontal direction is provided therein, and a plug receiving portion 7 that engages with the tongue piece 4 and the convex member 5 and a concave material 8 are formed on the opposite surface of the concave portion 4. Then, while inserting the tongue piece 4 of the cheek pad 2 into the insertion receiving portion 7 of the concave portion 3, the convex member 5 of the cheek pad 3 is fitted to the concave material 8 of the concave portion 3, and the elastic body provided inside the cheek pad 3 6 restores the cheek pad 2 to the recess 3.

A full face type helmet has a window opening in the front and a narrow chin cover formed in a lower portion of the window is open to the lower surface of the helmet continuously with the helmet body. Structurally, the lower end side of the helmet, that is, the periphery of the lower surface opening of the shell into which the wearer inserts the head is more easily deformed than the periphery of the window hole. For this reason, when the helmet is worn, if the left and right chin belts fixed to the inner surface of the shell are pulled outward, the opening at the lower surface of the shell tends to be deformed to have a larger diameter when the helmet is worn. Such deformation of the lower opening of the shell has the advantage that the helmet can be easily worn, but the above-mentioned Japanese Patent Publication No. 4-6.
As with the helmet proposed in No. 1082, when the cheek pad is removably attached to the inner surface of the shell, there is a surface where the cheek pad is easily dislodged due to deformation of the shell when the helmet is attached. In particular, the above-mentioned Tokuhei 4
In a configuration in which an elastic body 6 that is elastically deformed in the horizontal direction with respect to the shell 1 is provided inside the cheek pad 2 as in Japanese Patent No. When the lower surface opening of the shell 1 is deformed to have a large diameter when the helmet is worn, not only the fixation of the cheek pad 2 is loosened, but also when the helmet is worn, the wearer is inevitably inserted into the helmet from the lower surface opening of the shell 1 When the wearer's head is to be inserted inside the helmet in a state where the cheek pad 2 attached to the lower surface opening of the shell 1 and the wearer's head are in contact with each other, There is a possibility that the pad 2 is pulled upward and the cheek pad 2 comes off.
