Attachment for vehicle interior material

An attachment for a vehicle interior material to be mounted on a mounting hole for attaching a first component to the mounting hole formed in the vehicle interior material, the first component including a body portion and a head portion protruded from the body portion in a flange configuration, the body portion having at least one catch claw disposed therein, the at least one catch claw elastically displaceable in a radial direction of the body portion, the attachment for the vehicle interior material comprising:

• an abutment plate portion having dimensions that do not permit the abutment plate portion to be inserted into the mounting hole of the vehicle interior material, the abutment plate portion including an insertion hole formed in a middle portion thereof;
• at least one first retaining portion disposed on a back side of the abutment plate portion, the at least one first retaining portion insertable into the mounting hole of the vehicle interior material;
• and
• at least one second retaining portion disposed on the back side of the abutment plate portion, the at least one second retaining portion insertable into the mounting hole of the vehicle interior material,
• wherein a second component that has larger dimensions than the first component includes a body portion and a head portion protruded from the body portion in a flange configuration, the body portion having at least one catch claw disposed therein, the at least one catch claw elastically displaceable in a radial direction of the body portion, the second component can be attached to the mounting hole in the vehicle interior material by engaging the catch claw with a peripheral edge portion of the mounting hole,
• wherein the at least one first retaining portion and the at least one second retaining portion are inserted into the mounting hole with the second retaining portion aligned with a position at which the catch claw of the second component is engaged with the peripheral edge portion of the mounting hole, the abutment plate portion is abutted against the peripheral edge portion of the mounting hole in the vehicle interior material from a front side and the at least one first retaining portion is engaged with the peripheral edge portion of the mounting hole from the back side, and thereby the attachment is mounted on the mounting hole,
• wherein the insertion hole of the abutment plate portion is formed with dimensions that permit the body portion of the first component to be inserted thereinto and that do not permit the head portion of the first component to be inserted therein, and
• wherein the body portion of the first component is inserted into the insertion hole, the head portion of the first component is abutted against the abutment plate portion and the at least one catch claw of the body portion of the first component is engaged with the at least one second retaining portion, and thereby the first component is attached to the attachment.
