Helmet
First Claim
1. A helmet comprising a cap body including a shock-absorbing liner fitted inside a shell made of synthetic resin and a chin belt attached to the cap body, wherein a support portion is integrally formed on an inner surface of said shell for supporting a folded-back portion of said chin belt,wherein said shock-absorbing liner has a belt hole through which said chin belt is passed, in correspondence to said support portion of said shell to assist in fitting said liner to said shell,wherein a peripheral edge of a lower end of said shell is formed into a wave shape, while a wave-shaped upwardly-directed step with which the peripheral edge of said lower end of said shell is to be engaged is formed on an outer surface of said shock-absorbing liner,wherein said chin belt comprises a pair of left and right front belt elements, and a single rear belt element folded back at a central portion thereof, and said support portion is provided on an inner surface of said shell at each of three points:
- left and right side points and a rear point, folded-back portions at upper ends of said left and right front belt elements being supported by said support portions and said central portion of said rear belt element being supported by said support portion at said rear point, andwherein each of said left and right front belt elements has an adjusting plate attached to an intermediate portion thereof, each of left and right opposite ends of said rear belt element being connected to corresponding one of said adjusting plates for adjustment of the length of said rear belt element.

Abstract
Support portions are integrally molded on an inner surface of a helmet shell made of synthetic resin for supporting folded-back portions of a chin belt, and belt holes, through which the chin belt is passed, are provided in a shock-absorbing liner in correspondence to the support portions. Thus, the chin belt can be simply attached to a cap body without use of any separate support plate and rivet, thereby providing a cost reduction and a better external appearance.
