Abstract: In an attachment structure of an EA component, the EA component composed of a synthetic resin such as rigid urethane foam is attached to a trim serving as a member, with a first locking part therebetween. The first locking part includes a cylindrical part, an anchor, a flange, and a plurality of projections. The anchor has a flange shape extending from the rear end of the cylindrical part toward the outside. The flange extends from the leading end of the cylindrical part toward the outside. The projections protrude from the leading end of the cylindrical part in the direction parallel to the axis of the cylindrical part. The EA component is attached to the trim by setting the EA component on the trim while the projections are inserted in an opening.

Abstract: A mounting structure for an EA material is provided in which the EA material can be easily mounted to a member such as a trim, and EA materials of various shapes, sizes, and hardness degrees can be securely mounted to the member. An EA material 1 made of a synthetic resin such as rigid urethane foam is mounted to a trim 2, which serves as a member, via a rib 3 and a clip 4. The EA material 1 is mounted to the trim 2 by applying the EA material 1 to the trim 2 while inserting the rib 3 into a concave slit 7. When the EA material 1 is pressed against the trim 2, ribs 3 and 3A are pressed into concave slits 7 and 7A while sliding against the leading ends of respective pawls 5. Then, the leading ends of the respective pawls 5 dig into the side circumferential surfaces of the ribs 3 and 3A, and the ribs 3 and 3A are prevented from escaping from the concave slits 7 and 7A. Thereby, the EA material 1 is mounted to the trim 2.

A clip 20 has a flange 21 to be positioned at the surface of an EA member, a shaft 22 projecting from the flange 21 toward an EA-member side, an anchor 23 spreading from an end of the shaft 22 and to be embedded in the EA member, a cut 24 provided in the anchor 23, and a locking section 30 projecting from the flange 21 on a side opposite the shaft 22. The locking section 30 has a cylindrical upright segment 31 standing upright from the flange 21, and a locking piece 32 projecting laterally from the side surface of the upright segment 31 and resiliently thrustable and retractable in its projecting direction.

Abstract: An EA component and an attachment structure thereof capable of absorbing a positional error between a projection or the like on a side of a component such as a trim or the like, and a clip of the EA component. An EA component 1 is the one in which a clip 4 is integrally formed with an EA component body 3 formed from hard urethane foam via an elastically deformable component 20. The elastically deformable component 20 is provided with a hole 21 where a tubular portion 6 of a clip 4 made of hard synthetic resin is inserted, shallow and round concave portions 22 respectively provided in both end surfaces, and a slot 23.
