Door trim fastener assembly

Claim 2

A door trim fastener assembly, comprising, in combination, a fastener having a head portion and a neck portion of smaller size than the head portion, a trim panel including a planar backing layer and a resilient layer beneath the backing layer, the backing layer having a slot with a closed end and an open end through which the neck portion of the fastener is receivable and having a width less than the width of the head portion of the fastener, the planar backing layer further including a flap hinged thereto of a width sufficient to receive the fastener head portion through the backing layer as the head portion moves the flap between a first position substantially coplanar with the backing layer and at least partially traversing the slot to block removal of the neck portion of the fastener from the slot and a second position resiliently compressed into the resilient layer as the fastener is moved substantially perpendicularly to the backing layer to allow insertion of the neck portion of the fastener through the open end of the slot, the flap moving back to first position under the resiliency of the resilient layer to retain the fastener.

Claim 3

A door trim fastener assembly comprising, in combination, a fastener having a head portion and a neck portion of smaller size than the head portion, a trim panel including a planar backing layer and a resilient layer beneath the backing layer, the backing layer having a first slot with a closed end and an open end through which the neck portion of the fastener is receivable and having a width less than the width of the head portion of the fastener, whereby the head portion lies inwardly of the planar backing layer to either side of the first slot when the neck portion is received in the first slot, the planar backing layer further including a second slot opening to the open end of the first slot and of a size to receive the head portion of the fastener therethrough to allow the fastener to be inserted into the first slot while remaining generally perpendicular to the backing layer, the backing layer further including a flap hinged thereto and coextensive with the second slot and movable by the head portion of the inserted fastener between a first position substantially coplanar with the backing layer and blocking the open end of the slot to trap the neck portion of the fastener between the end of the flap and the closed end of the slot, and a second non-coplanar position with respect to the backing layer resiliently compressed into the resilient layer to allow movement of the head portion of the fastener through the second slot and into inwardly lying relationship to the backing layer to either side of the first slot, the resiliently compressed flap moving back to first position after fastener insertion to retain the fastener.

Claim 4

A door trim fastener assembly comprising, in combination, a fastener having a head portion and a neck portion of smaller size than the head portion, a trim panel including a planar backing layer and a resilient layer beneath the backing layer, the backing layer having a first slot with a closed end and an open end through which the neck portion of the fastener is receivable and having a width less than the width of the head portion of the fastener, whereby the head portion lies inwardly of the planar backing layer to either side of the first slot when the neck portion is received in the first slot, the planar backing layer further including a second slot opening to the open end of the first slot and of a size to receive the head portion of the fastener therethrough to allow the fastener to be inserted into the first slot while remaining generally perpendicular to the backing layer, the backing layer further including a flap hinged thereto and coextensive with the second slot and movable by the head portion of the inserted fastener between a first position substantially coplanar with the backing layer and blocking the open end of the slot to trap the neck portion of the fastener between the end of the flap and the closed end of the slot, and a second non-coplanar position with respect to the backing layer resiliently compressed into the resilient layer to allow movement of the head portion of the fastener through the second slot and into inwardly lying relationship to the backing layer to either side of the first slot, the resiliently compressed flap moving back to first position after fastener insertion to retain the fastener.

Claim 5

A door trim fastener assembly comprising, in combination, a fastener having a head portion and a neck portion of smaller size than the head portion, a trim panel including a planar backing layer and a resilient layer beneath the backing layer, the backing layer having a first slot with a closed end and an open end through which the neck portion of the fastener is receivable and having a width less than the width of the head portion of the fastener, the planar backing layer further including a second slot opening to the open end of the first slot and colinear therewith and of a size to receive the head portion of the fastener therethrough to allow the fastener to be inserted into the first slot while remaining generally perpendicular to the backing layer, the backing layer further including an integral flap integrally hinged thereto for movement between a first position substantially coplanar with the backing layer and blocking the open end of the first slot to trap the neck portion of the fastener between the flap and the closed end of the first slot and locate the head portion of the fastener lying inwardly of the backing layer to either side of of the slot, and a second position compressed into the resilient layer by the head portion of the inserted fastener to allow movement of the head portion of the fastener through the second slot and into inwardly lying relationship to the backing layer to either side of the first slot, the flap being die cut from the backing layer and being frictionally retained in the first position by engagement with the backing layer as the flap resiliently returns to first position.

Claim 6

A door trim fastener assembly comprising, in combination, a fastener having a head portion and a neck portion of smaller size than the head portion, a trim panel including a planar backing layer and a resilient layer beneath the backing layer, the backing layer having a first slot with a closed end and an open end through which the neck portion of the fastener is receivable and having a width less than the width of the head portion of the fastener, the planar backing layer further including a second slot opening to the open end of the first slot and colinear therewith and of a size to receive the head portion of the fastener therethrough to allow the fastener to be inserted into the first slot while remaining generally perpendicular to the backing layer, the backing layer further including an integral flap integrally hinged thereto for movement between a first position substantially coplanar with the backing layer and blocking the open end of the first slot to trap the neck portion of the fastener between the flap and the closed end of the first slot and locate the head portion of the fastener lying inwardly of the backing layer to either side of of the slot, and a second position compressed into the resilient layer by the head portion of the inserted fastener to allow movement of the head portion of the fastener through the second slot and into inwardly lying relationship to the backing layer to either side of the first slot, the flap being die cut from the backing layer and being frictionally retained in the first position by engagement with the backing layer as the flap resiliently returns to first position.
