Abstract

A trim retainer assembly having a clip portion with a base and a molded housing having a keyhole and an opening. The keyhole in the doghouse is smooth for improved molding and elimination of tuning since there are no detents in the bore to tune or maintain. The base is provided with a pair of arms that are flexible and each arm having a self detent feature that passes through the opening in the housing to provide clip retention and, at the same time, float for tolerance variations is provided. The pair of arms also include nominal centering detents. The keyhole bore, opening, and clip portion provides clip detent, consistent retention effort, float, centering and anti-rotation.

First claim

What is claimed is:

1. A trim retention assembly, comprising:
a housing having an opening;
a clip portion having a base with a flexible portion insertable in a longitudinal clip load direction of a longitudinal axis into the opening;
at least one self detent feature located at a leading terminal end of the flexible portion to insert the flexible portion through the opening in the housing and to keep the flexible portion within the opening;
at least one protruding stop located on the base a predetermined distance from the at least one self detent feature, wherein the distance between the at least one self detent feature and the at least one protruding stop provides a length of allowed movement of the flexible portion, while within the opening, with respect to the longitudinal axis to accommodate tolerance variations;
an aperture located on the housing;
a neck area formed on the clip portion transverse to the longitudinal axis of the flexible portion, wherein the neck area of the clip portion is slidable within the aperture while the flexible portion is moving longitudinally within the opening; and
at least one centering detent formed in the base to center the clip portion.

2. The trim retention assembly of claim 1 , wherein the aperture includes a bore that is smooth.

3. The trim retention assembly of claim 2 , wherein the bore has a predetermined width wider in relation to the neck area to provide the neck area with side to side movement within the bore to accommodate tolerance variations when the flexible portion is within the opening.

4. The trim retention assembly of claim 1 , wherein the neck portion is coupled to a larger diameter portion that is located outside the aperture when the base is located inside the housing.

5. The trim retention assembly of claim 1 , wherein the at least one self detent feature is a pair of self detent features, wherein the flexible portion is a pair of flexible arms, each having one of the self detent features, and the opening is a detent-pass through opening to receive the self detent features of the pair of flexible arms.

6. The trim retention assembly of claim 5 , wherein the at least one centering detent is a pair of centering detents protruding from each flexible arm.

7. A trim retention arrangement, comprising:
a housing having an opening and an aperture with a smooth bore;
a clip portion having a base with a flexible portion, wherein the flexible portion has a pair of flexible arms;
a self detent feature formed at a leading terminal end of each flexible arm to compress the pair of flexible arms inward for passing the pair of flexible arms into the opening in the housing and to keep the pair of flexible arms within the opening;
a protruding stop formed on each side of the base at a distance away from the self detent features to allow the pair of flexible arms to slide back and forth within the opening, with respect to a longitudinal axis, with the amount of back and forth that is allowable being the length of the distance between the self detent feature and the protruding stop to absorb tolerances;
a neck portion formed on the clip portion transverse to the longitudinal axis, wherein the neck portion slides within the aperture when the pair of flexible arms slide within the opening;
wherein the bore has a predetermined width wider than the neck portion to provide side to side movement of the neck portion within the bore to absorb tolerances when the pair of flexible arms are within the opening.

8. The trim retention assembly of claim 7 , wherein the flexible arms are arranged parallel to one another.

9. The trim retention assembly of claim 7 , further comprising adjacent centering detents formed on the pair of flexible arms.

10. The trim retention assembly of claim 9 , wherein the adjacent centering detents are a pair of centering detent spaced a predetermined distance apart and located transverse to the longitudinal axis of each flexible arm.

11. The trim retention assembly of claim 10 , wherein the pair of centering detents are protrusions or raised ridges or ribs.

12. A trim retention assembly for an automotive trim component, comprising:
a molded doghouse having a slot on an end of the molded doghouse and having an aperture transverse to the slot, wherein the aperture has a smooth bore with a predetermined width;
a clip portion having a pair of flexible arms and a neck portion, said neck portion disposed between a base and a larger diameter portion of the clip portion and selectively slid into and retained in the bore, wherein the neck portion is narrower than the width of the bore to provide the neck portion with space to move in either direction transverse to a longitudinal clip load direction of the neck portion into the bore to accommodate any tolerance in the attachment of the trim component;
a pair of centering detents on each flexible arm; and
a self detent feature formed at a terminal end of each flexible arm, each self detent feature being ramped for passing through the slot in the molded doghouse and returning to an outward position to keep the pair of flexible arms within the slot.

13. The trim retention assembly of claim 12 , wherein the clip portion does not rotate relative to the molded doghouse once the self detent feature is passed through the slot in the molded doghouse and returns to the outward position.
