The heating element circuit cover member 14 has opened portions 14a and 14a for not covering connection end portions 12a and 12a and their surroundings. The connection end portions 12a and 12a and their surroundings, and portions of the lead wires 17 and 17 above the base member 10 are covered through a heat-resistant adhesive 20 with an end portion cover member 22 provided separately from heating element circuit cover member 14.

Abstract: In a bored headrest, a garnish includes a front garnish and a rear garnish that are attached to a through-hole of a skin member in front and rear directions of the through-hole to seal an opening. The front garnish has a first holding portion that can hold a first skin edge portion, and a first connecting portion formed at a near side to the rear garnish. The rear garnish has a second holding portion which can hold a second skin edge portion, and a second connecting portion formed at a near side to the front garnish. The rear garnish has a second connecting portion. Therefore, a bored headrest is provided having a high quality of appearance and whose quality of appearance can be kept constant.

Abstract: A flexible heating sheet is composed of two heat fusible aromatic polyimide films and an electric heating element having an electric source-connecting terminal at each end which intervenes between the heat fusible aromatic polyimide films, in which each heat fusible aromatic polyimide film is covered with a heat resistant aromatic polyimide film.
