A method of manufacturing a headrest including a stay, a skin material, a cushion material, and a dynamic damper is provided. The method includes arranging the skin material in a molding die, arranging the stay, to which an air bag is attached in such a manner as to cover the dynamic damper, inside the skin material, and injecting a foamable synthetic resin raw material into the skin material to foam-mold the injected foamable synthetic resin raw material integrally with the stay.

Headrest and method of manufacturing the headrest

A headrest includes a stay, a skin material, a cushion material and a dynamic damper. The cushion material is foam-molded integrally with the stay inside the skin material, and has a hollow portion therein. The dynamic damper is attached to the stay, and is disposed in the hollow portion in such a manner as not to abut on the cushion material.

A vehicle seat includes a seat back, and a headrest that is provided above the seat back. The headrest includes a pair of stays that form a part of a skeleton of the headrest, a pair of panel members that sandwich parts of the pair of stays from front and rear or above and below so as to connect the stays with each other, and are joined to each other through outer peripheries so as to form a space inside and form a part of the skeleton of the headrest, a cushion material that covers the pair of panel members and the parts of the pair of stays, and a dynamic damper arranged inside the space.

Headrest and vehicle seat having headrest

A vehicle seat includes a skeleton member, panel members that are attached to the skeleton member and has a space inside, and a dynamic damper that is provided with a weight and an elastic body and arranged inside the space. The weight is fixed by being fitted into a fitting part, the fitting part being provided in the elastic body and formed so as to encircle and be able to be fitted to a part of an outer periphery part of the weight. A part other than the fitting part in the elastic body is fixed to the panel members.

Vehicle seat

A vehicle seat includes a seat back and headrest provided with a stay, a pair of panel members that sandwich a part of the stay from front and rear or above and below, and joined to each other through outer peripheries so as to form a space inside, a cushion material formed so as to cover the panel members and the part of the stay, and a dynamic damper arranged inside the space. The dynamic damper has a weight, and an elastic body that fastens the weight and has a leg part extending in a direction away from the weight. A part of the leg part is attached to the pair of panel members by being sandwiched by the pair of panel members.
