Abstract:
A damping device according to one embodiment includes a base member fixed to a vibration suppression target, a first coil spring, a second coil spring, and a weight member. The first coil spring includes a first fixed-side end turn portion supported on a first support portion of the base member, a first effective portion, and a first movable-side end turn portion. The second coil spring includes a second fixed-side end turn portion supported on a second support portion of the base member, a second effective portion, and a second movable-side end turn portion. Each of the first coil spring and the second coil spring is deflected in a longitudinal direction along the axis, and a transverse direction perpendicular to the axis. The weight member is arranged between the first coil spring and the second coil spring, and moves in the longitudinal direction and the transverse direction.

Claim (Index 12):
A damping device arranged in a vehicle seat comprising a seat cushion and a seat back, a first resonance frequency in a vertical direction of the seat back being greater than a second resonance frequency in a front-to-back direction of the seat back, and the damping device comprising:\n a base member including a main body portion including an axis, a first support portion provided on one side of the main body portion in an axial direction thereof, and a second support portion provided on the other side of the main body portion in the axial direction, the base member being fixed to the seat back such that the axis is parallel to a width direction of the seat back; a first coil spring formed of a first wire, the first coil spring including a first fixed-side end turn portion supported on the first support portion, a first effective portion extending in a direction toward the second support portion helically from the first fixed-side end turn portion, and a first movable-side end turn portion formed at a distal end of the first effective portion, the first effective portion including a first end-turn adjoining portion whose contact with the first fixed-side end turn portion is controlled, and a second end-turn adjoining portion whose contact with the first movable-side end turn portion is controlled, such that a number of active turns of the first wire of the first effective portion when deflection occurs in the front-to-back direction of the seat back becomes greater than a number of active turns of the first wire of the first effective portion when deflection occurs in the vertical direction of the seat back; a second coil spring formed of a second wire, the second coil spring including a second fixed-side end turn portion supported on the second support portion, a second effective portion extending in a direction toward the first support portion helically from the second fixed-side end turn portion, and a second movable-side end turn portion formed at a distal end of the second effective portion, the second effective portion including a third end-turn adjoining portion whose contact with the second fixed-side end turn portion is controlled, and a fourth end-turn adjoining portion whose contact with the second movable-side end turn portion is controlled, such that a number of active turns of the second wire of the second effective portion when deflection occurs in the front-to-back direction becomes greater than a number of active turns of the second wire of the second effective portion when deflection occurs in the vertical direction of the seat back; and a weight member arranged between the first coil spring and the second coil spring in a state of compressing the first coil spring and the second coil spring, the weight member including a first end portion supported on the first movable-side end turn portion, and a second end portion supported on the second movable-side end turn portion, and being moved in at least the width direction, the front-to-back direction, and the vertical direction of the seat back, wherein a spring constant of each of the first coil spring and the second coil spring when the weight member moves in the front-to-back direction of the seat back is smaller than a spring constant derived when the weight member moves in the width direction and the vertical direction of the seat back.
