Status Attainment of Costa Rican Males: A Cross-Cultural Test of a Model.

A protective-type helmet expressly for use by a motorcyclist and unique in that a pair of manually controlled spring-loaded door-like lids or ear flaps are hingedly installed for coaction with hearing holes located in line with the user's ears. When fully open, the ear flaps stay put until intentionally closed by the wearer. Being spring-biased and correctly aligned and pivotally mounted they stay normally closed. Each door or flap embodies a suitable rubber gasket inside to provide and to insure a reliable airtight seal while the motorcycle is in motion. A smaller but similar spring-loaded pivoted door or flap is mounted on the median lower portion of the helmet's rear wall to permit an appropriate normally spring-loaded door to be used in a convenient manner to fasten and anchor the helmet on a part of the motorcycle which is not being ridden. All three doors may be basically alike in construction and general manner of use.
