Abstract
A massage system is provided that includes a motor having an output shaft and at least one sliding block connected to the output shaft. The massage system also includes at least one bellows. Each bellows is connected to a corresponding one of the sliding blocks and is moveable between an extended position and a retracted position. When each bellows is moved from the extended to the retracted position air is expelled from the bellows. Similarly, when each bellows is moved from the retracted to the extended position air is taken into the bellows. Operation of the motor causes each sliding block to move between a first position and a second position, such that in the first position each sliding block compresses a corresponding one of the bellows to the retracted position and in the second position each sliding block releases said corresponding one of the bellows to the extended position.
