One-piece actuation button for vehicle seat recliner

摘要

One-piece plastic actuation button for a vehicle seat adjuster providing ready snap-in interlocking capture of the button in a panel elongated opening while permitting smooth reciprocal travel therein. The button comprises an elongated head portion having its undersurface formed with a coextensive guide channel sized to receive therein a tongue portion of a seat adjust lever. The channel cooperates with upper and lower vertically spaced stem portions projecting normally from the button face to swing the tongue and operate the release lever. The upper stem portion is a push-in retainer comprising bifurcated mirror-image hook-halves defining a slotted intermediate space therebetween and two opposed outwardly divergent slopes terminating in a pair of undercut locking shoulders. The hook-halves are resiliently deformable between a normal inserted locking condition wherein the tongue portion is received in the intermediate space and a compressed condition wherein the slopes permit push-in insertion in the panel opening.
