SINTEC announces global campaign for turning the SeatBridge patented solution into a production reality


Italian SINTEC is starting a worldwide communication campaign to raise awareness about the SeatBridge solution, which has been granted the Italian Patent N. 102016000060616 and is expected to complete the European patenting process in late 2019.

SeatBridge offers an effective solution to the issues that characterize the conventional seat mounting system, in which seats are connected to the floor through a pair of rails.

Consisting of a bridge-shaped structure that raises the position of the rails and frees up the space underneath, and can integrate the center tunnel into a single module, the SeatBridge solution can be fully adopted in any production line with additional benefits in terms of process simplification.

At the moment SINTEC is the sole owner of the exclusive rights to produce, use, market, sell or import on the Italian national territory.

In order to turn this concept into a production reality that could benefit the entire automotive industry and car passengers from all over the world, SINTEC is advancing the negotiations currently in place as well as looking for new companies and organizations willing to incorporate this solution into their production lines or to invest for reserving exclusive rights for licensing once the solution is implemented - which in SINTEC's point of view will happen in the next future due to the objective advantages it brings.

SINTEC founder Claudio Buccini commented "The current standard seat mounting solution has reached a high level of standardization but has not progressed in decades and still suffers from the same problems: it leaves little space for rear passengers' legs and feet, and with its cluttered, primitive look, it detracts from the elegance and design of any car interior - even on luxury vehicles."

"For this reason, and also due to the revolution that electric cars will bring in terms of platform architecture, it's only a matter of time until the SeatBridge solution is widely implemented."

"SINTEC already owns exclusive rights for Italy and will soon be granted the European patent. We are actively speaking with several companies to move to the production phase, because we believe this will solution ultimately benefit not only car passengers, but also car manufacturers and suppliers.”

"Today there is an opportunity for those companies that are willing to invest for either developing the technology or ensure licensing rights for the future. Negotiations are in place but as it happens in these cases it's likely to be a first-come, first-serve deal: that is why our message for this communication campaign is “...if you don’t choose SeatBridge...someone else will do it !”"

The Italian Ministry of Economic Development has issued the Patent for the SINTEC SeatBridge car seats innovative mounting solution


The Problem

Most, if not all, of the front seats of production cars are currently mounted separately on two rails directly connected to the floor.

These rails provide an easy way for adjusting the seats longitudinal position, but have a major drawback: they significantly reduce the foot space available to the rear passengers, also reducing the comfort and without any aesthetic as well.

The goal was to find a solution to this problem in order to give rear passengers a much larger foot space and to achieve a better, uncluttered look.

The Solution

The proposed solution is to raise the position of the front seats sliding elements by inserting a"bridge" structure made of a folded metal sheet (or equivalent functional element).

The patent pending solution, that integrates the front seats mountings as well as the center console.

The structure is connected to the car’s structure in the door sills and center tunnel areas.


Save your feet - and your Shoes!

Experience a better travel comfort and never scratch your shoes again

Clean, elegant look

No more ugly metal rails, but a minimal, uncluttered look with full-size carpets

More usable space for your things

Use the taller space under the seats to store a bag, or whatever you like

For passengers

  • Aesthetic
  • Feet comfort and space, + 40%
  • Easier cleaning
  • Single removable carpet each seat

For seat makers

  • Innovation
  • Higher market volume
  • Value increase of delivered good: not only seats but also central consolle and accessories
  • No constraint for geometries

For car makers

  • Simplified production line: one side only to assemble front seats
  • A single configuration item, i.e.: the Front SeatBridge Assembly, which includes: left seat, right seat, central console, wirings, left rail, right rail, safety belts lock, etc.
  • Lower production costs: one robot only, less items to be installed, less wiring, etc.
  • Lower logistics costs: only one item to be purchased, received, stored, managed
  • Innovation

Production Improvements

Possible Applications

Two-seat city car

D-Segment Passenger Car

Today: under the driver’s seat of a D-Segment passenger car (2013 model)

Tomorrow: a much more uncluttered design, without doing any modification to the seat components

Note: the sliding device is not part of the patent; the Patent Application document shows possible and easy solutions

Premium SUV

Today: under the driver’s seat

Tomorrow: the SeatBridge enables to have a free, usable space

Driver Seat - Rear View


Without the rails

Tomorrow: with the SeatBridge

Premium SUV

From a "workshop look"... to a "Sitting Room look"

Today: the mounting system of the driver’s seat

Tomorrow: much bigger foot room, cleaner, more premium look

Questions and Answers

For the sake of clearness and transparency, hereinafter we include some possible concerns that could be raised by this solution, as it always happen when innovation has to be assessed.

  • The hip position is not correct: The hip position is totally in the hands of the designer
  • The strength of the car can be decreased: The car strength does not depend on current front seats mounting systems. SeatBridge makes it possible the creation of a transversal reinforcement under the front seats, hence dramatically increasing, if needed, lateral impacts resilience.
  • The cost is too high: The cost of the SeatBridge itself is only a little bit higher than the present-day rails solution, but the cost of the car decreases due to the much easier installation of the whole Front Seats Assembly which includes also the Central Console and all wirings for: safety belts, passenger presence sensor, lighting, heating, A/C, other Car Controls.
  • The solution could implicate some weight increase: True, but it is in the 1-8 kg range only, starting from an aluminum solution for a Fiat 500, to a steel solution for a Mercedes-Benz S Class.
  • The adoption of the suggested solution needs modifications to the car floor: To be studied case by case of course, but new car floors will be more simple of current ones; proper solutions can be easily studied for existing car floors.
  • The Bridge Structure could disturb the legs of passengers when seats are moved full forward or backward: It is a matter of design and trade off to be managed according to the car size, easy to be solved
  • Seat structures will have to be modified: not so much, because all mechanical/electric parts of the seat are today “included” into the seat; SeatBridge will not modify them.
  • The connection between the seats and the SeatBridge is not part of the patent; anyhow the patent application includes some specific proposals that show the ease of the assembly.

SeatBridge is a win-win-win solution:

  • Users win: more space, aesthetics and comfort
  • Cars Makers win: cars are build with less time and cost due to easier logistics and installation
  • Seats Makers win: higher turnover due to the additional labour that they will supply with the Front Seats Assembly
