Automotive & Aerospace Seating
Seating systems are growing in complexity as manufacturers look to incorporate additional safety features with improved comfort and performance. Lumbar support and massage systems improve passenger comfort and combat driver fatigue.
Typical systems use a single pump connected to a series of bladders via an array of valves. Due to its large size, the pump is normally mounted beneath the seat and away from the passenger; this also helps to limit the transmission of noise and vibration to the passenger. The pump is then connected to the bladders via a complex system of pipework that is often internally reinforced to prevent kinking.
Owing to its ultrasonic operation, Disc Pump™ is silent and vibration free. This offers a greatly-enhanced user experience and allows the pump to be positioned anywhere in the seat. This opens up the option for a 'distributed pump' architecture, offering improved reliability through redundancy and reduced duty cycle. Each pump can be mounted directly to a corresponding bladder, removing the need for complex interconnecting pipework, simplifying the design process and eliminating a frequent source of leaks.
At just 5g (1/5 oz), Disc Pump's compact and lightweight form factor help to keep the seat weight to a minimum. This is of particular importance in aircraft seating.
