HEAD REST

摘要

PROBLEM TO BE SOLVED: To telephone or listen to music in a comfortable position in a passenger car. SOLUTION: A stereophonic speaker 3 is embedded in a head rest 2 so as to correspond to the position of the ear of a person seated in a seat. The head rest 2 is electrically moved upward and downward so as to correspond to the seated height of the person and width or angle can be also adjusted. A microphone embedded in the head rest or an elbow rest is used to speak without employing a hand. When listening to music, the speaker 3 of the head rest 2 is connected in place of a headphone. The sound of the speaker 3 of the head rest 2 does not hardly leak, so that the speech is not heard by other passengers or not causes them trouble.
