  • Arrangement for damping oscillating movements in vehicle seats
    Patent number: 4195883
    Abstract: A vehicle seat is carried on a frame which is pivotably mounted on a base frame that is secured to the vehicle floor. The seat can pivot around an axis that is essentially horizontal and transverse to the vehicle direction of travel. There is provided at least one damping element for damping pivotations around said axis. In this way disturbing thrusts transferred to the back of a person via the back support portion of the seat are eliminated.
