Massage system for a vehicle seat

A massage system of a vehicle seat comprising:

• first, second, and third air cells adapted to inflate upon receipt of air;
• a common supply line in direct fluid communication with each one of the first, second, and third air cells, and adapted to flow air in supply flow direction to inflate the first, second, and third air cells, wherein the first air cell is located upstream of the second air cell and the second air cell is located upstream of the third air cell with respect to the supply flow direction;
• a first flow restrictor located in the common supply line upstream of the first air cell with respect to the supply flow direction;
• a second flow restrictor located in the common supply line upstream of the second air cell, and between the first and second air cells, wherein air flowing through the second flow restrictor in the supply flow direction is supplied by the first flow restrictor;
• and
• a third flow restrictor located in the common supply line upstream of the third air cell, and between the first and second air cells, wherein air flowing through the third flow restrictor in the supply flow direction is supplied by the second flow restrictor.

A massage system comprising:

• a common line adapted for the flow of supply air and the opposite flow of venting air, the common line including and extending between first and second portions;
• first and second flow restrictors arranged in series along the common line for controlling the flow of the supply air and the venting air;
• an air pump adapted to provide the supply air and in fluid communication with the second portion;
• a first pair of air cells in fluid communication with and individually branching off from the first portion;
• and
• a second pair of air cells in fluid communication with and individually branching off from the common line between the first and second portions, wherein the second flow restrictor is disposed between the second pair of air cells and the pump, and the first flow restrictor is disposed between the first and second pairs of air cells.
