Pneumatic and vibration providing device for vehicle seat

A pneumatic and vibration generating device for a vehicle seat, the pneumatic and vibration generating device comprising:

• a first air bladder mounted in a seatback and configured to be inflated and deflated in the seatback;
• a vibration motor disposed on a front portion of the first air bladder and configured to selectively generate vibration;
• and
• wherein the vibration motor has a fusion sheet provided on one surface side thereof, wherein the fusion sheet has an edge portion entirely fixed to the first air bladder by thermal fusion, and
• wherein a rear portion of the first air bladder has a first bladder connection portion and a front portion of the second air bladder has a second bladder connection portion, wherein the rear portion of the first air bladder and the front portion of the second air bladder are coupled to each other through the thermal fusion of the first and second bladder connection portions performed at an outer location of the vibration motor, and the first and second bladder connection portions have first and second air communication ports each formed to be perforated at central portions of the first and second bladder connection portions and configured to enable the air to flow between the first air bladder and the second air bladder,
• a second air bladder provided on a rear end surface of the first air bladder and configured to be inflated and deflated, wherein the second air bladder is operatively connected to the first air bladder so as to enable air to flow therebetween,
• wherein the vibration motor has a fusion sheet provided on one surface side thereof,
• wherein the fusion sheet has an edge portion entirely fixed to the first air bladder by thermal fusion, and
• wherein a rear portion of the first air bladder has a first bladder connection portion and a front portion of the second air bladder has a second bladder connection portion, wherein the rear portion of the first air bladder and the front portion of the second air bladder are coupled to each other through the thermal fusion of the first and second bladder connection portions performed at an outer location of the vibration motor, and the first and second bladder connection portions have first and second air communication ports each formed to be perforated at central portions of the first and second bladder connection portions and configured to enable the air to flow between the first air bladder and the second air bladder.
