HEADREST AND VEHICLE SEAT PROVIDED THEREWITH, AND METHOD OF MANUFACTURING HEADREST

摘要

It is obtained a headrest and a vehicle seat provided therewith and a method of manufacturing a headrest, that can reduce load to a neck portion of a vehicle occupant at a time of a rear collision while ensuring NV performance. A first urethane and a second urethane are disposed at an inner side of a headrest skin of a vehicle seat, and structure a headrest pad. The first urethane is embedded in the second urethane, and is elastically deformable, and supports a mass body. An elastic coefficient of the second urethane is set to be higher than that of the first urethane.

主权项

1. A headrest comprising:
a headrest stay that has leg portions that are supported at a seat back and that extend in a seat height direction; a first cushion material that is disposed at an inner side of a headrest skin, that supports a mass body and is formed of an elastically deformable urethane, and that is fixed to the headrest stay by adhesive force of the urethane itself; and a second cushion material that is disposed at the inner side of the headrest skin, that structures a headrest pad together with the first cushion material, and that is formed of a urethane having a higher elastic coefficient than the first cushion material.
