HEADREST AND VEHICLE SEAT PROVIDED THEREWITH

摘要

It is obtained a headrest and a vehicle seat provided therewith, capable of obtaining attenuating effect characteristics with respect to oscillation at two resonant frequencies with a simple configuration. A mass body is supported by an elastically deformable first urethane member configuring part of a headrest pad inside a headrest cover of a vehicle seat. Namely, a dynamic damper is configured including the first urethane member and the mass body. The center of gravity of the mass body is set at a position offset in the seat width direction with respect to the elastic center of the first urethane member.

主权项

1. A headrest comprising:
a headrest pad disposed inside a headrest cover, and including an elastically deformable cushion portion configuring part of a dynamic damper; and a mass body configuring part of the dynamic damper and supported by the cushion portion with a center of gravity of the mass body set at a position offset with respect to a elastic center of the cushion portion, wherein the headrest pad includes a first cushion material configuring the cushion portion and a second cushion material with a higher elastic modulus than the first cushion.
