  • Padding for a vehicle seat
    Patent number: 6206474
    Abstract: A car seat is provided with upholstery with liquid-filled chambers in which the liquid also has elastic bodies. The chambers are connected to one another through passages, so that a liquid exchange can take place among the individual chambers. The damping and resilience properties of the upholstery can be influenced by liquids of different viscosity and/or passages of different shape and size. The upholstery can be used over the full surface of a car seat or selectively in certain areas thereof.
