Vacust is a support with stabilized shape and memory achieved using a vacuum process and can change from being soft to being rigid, and they create a negative mold of what they are in contact with.
Through the use of small electric pumps capable of also producing a vacuum with a special 
foam coupled with different materials with closed or very open cells, we create new intelligent material where we can have the e control of the shapes, the energies of the foam, where the volumes can grow but also decrease, offering a performance not known until now that allows dozens of possible interesting applications.
The seat can become narrower, it can freeze the user’s shape, it can become softer or more rigid, and it can offer a new type of massage or an anti-fatigue, anti-decubitus, anti-cellulite, and lymphatic drainage system. All this can be managed by a user in manual mode, or completely automatically.
Foamvac is a solution that transforms a stupid foam into an intelligent foam, and it finds application in many areas of the vehicle interior, it can be on the driver’s seat but also on the rear seats, in the headrest, armrest, and even in the door panel. Foamvac is a smart surface that is able to move shapes and soften on demand.
With the press of a single button, the seat will change from its ergonomic asset, ideal for long trips, to its race asset. The seat will be wrapped around its user, and it will be integral to his body like the best Formula One seat. Under vacuum the softness of the seat changes.
You can consider stiffening a normal seat to make it wrap like a racing car seat. But we can also break the current comfort/performance limits in both directions: we can have a large, super soft seat as a standard setting, and then cross all the intermediate softness levels till the point where we get a super stiff seat.
Foamvac is represented by the use of foam inside the lumbar support bladder. The “D” shape that the foam is able to remember and maintain perfectly fills the lordosis cavity, offering a large contact surface and a softness that increases with increasing volume. A super advanced lumbar allows control of four independent volumes. It works as a normal lumbar, high support, low support, and massage system.
Foamvac Features in Lumbar Seats:
- Foamvac support has a D shape that fills the lordosis with a large contact surface.
- The lumbar support filled with foam can count on the constant bearing capacity of the polyurethane and will offer greater resistance near the greater load, offering real support.
- The foam that recovers its volume coming out of the vacuum state recovers its softness. The increase in the volume of Foamvac has an increase in softness.
- Without volume has the same contact area
Health & Wellness: With the press of a single button, the seat will change from its ergonomic asset, ideal for long trips, to its race asset. The seat will be wrapped around its user, and it will be integral to his body like the best Formula One seat. Under vacuum the softness of the seat changes.
The golden rule of sciatica prevention is to avoid sitting for hours. Walking for 30 minutes a day increases blood flow to the nerve and reduces inflammation around it. With our system, we simulate a walk-by alternatively decompressing the buttocks.
The sciatic nerve is located under the piriformis muscle which is located under the buttocks. When the piriform strains pinch the sciatic nerve, tingling or numbness is felt. To reduce this pain is necessary to massage the irritated areas of the piriformis muscle, as well as the muscles of the lower back.
The Vacsar system, tiredness of the legs, tingling, and pain in the buttock are prevented. The need to stop the vehicle to get off and walk is no longer foreseen. The evolved Lumbar Foamvac system offers greater support with great volume and softness in the lordosis area. The lumbar in four sections allows a perfect adjustment of volumes according to the height of the occupant. An alternating volume increase function with an oblique orientation greatly helps to relax the back muscles, relieving fatigue in a very pleasant and gradual way.
VCM: Vacust control module board can manage up to 9 different channels, activate timed ignition sequences, monitor the external pressure and the negative pressure inside the FoamVac pads, record individual adjustments, and compensate for pressure changes due to altitude changes. It is able to communicate with any device, from the PC to the tablet with a dedicated app.
Starting from a standard seat, able to integrate the different functionalities of the FoamVac 
and Vacust technologies. The process involves defining the performance that the customer wants to achieve and our advice on the type of integration.
There is an intermediate phase of testing and trimming of the volumes and lift to be shared with the comfort team and ergonomics and then proceed to the choice of materials and seat upholstery. The pneumatic systems and related controls and activation procedures are another part of shared development for which we are able to offer the desired advice and functionality.
Intelligent anti-fatigue adaptive seat with subjective self-adjusting in real-time
A smart seat connected to a smartphone monitors the users and moves the seat according to the body’s needs.
