Abstract

A driver'"'"'s seat having a vibration generator connected to the driver'"'"'s seat and controls for turning the vibration generator on and off for vibrating the driver'"'"'s seat so that when a driver feels drowsiness coming on, the driver can operate the controls for switching on-off the vibration generator so that the driver'"'"'s seat can be vibrated and prevent the driver from dozing during driving and prevent an accident from occurring.

Claims

1. An apparatus for vibrating a seat comprising:

a driver'"'"'s seat;

means for vibrating said driver'"'"'s seat; and

means for controlling the vibration of said means for vibrating the driver'"'"'s seat,

wherein said means for vibrating said driver'"'"'s seat comprises a motor elastically connected to a pulley base, a power transmission shaft and a belt operably connecting an output shaft of said motor and said power transmission shaft,

wherein said means for vibrating said driver'"'"'s seat further comprises an eccentric load mounted on said power transmission shaft and extending along at least a part of a length thereof, and

wherein said pulley base is mounted beneath said driver'"'"'s seat, said power transmission shaft being operably coupled to walls of said pulley base, wherein said motor is mounted beneath said pulley base.

2. The apparatus for vibrating a seat as in claim 1, further comprising a seat base mounted directly beneath said driver'"'"'s seat, wherein said pulley base is directly mounted beneath said seat base.

3. The apparatus for vibrating a seat as in claim 2, wherein said walls of said pulley base have apertures for respectively accommodating therein opposing end portions of said power transmission shaft which extends along a length of said pulley base.
