Embodiment Construction

[0015] Referring now to the accompanying drawings, the figure 1 An actuation rod assembly, generally indicated at 10, is shown in . The actuation lever assembly 10 includes a lever arm 12 supported on a base structure (not shown) for pivotal movement between different positions. For example, the actuator lever assembly 10 may be pivotally mounted on a steering column module (not shown) of a vehicle to selectively operate turn signals, headlight beams, wipers, and the like. To facilitate movement between the different positions, the illustrated actuator rod assembly 10 includes a plunger-type actuator assembly, generally indicated at 20 . The actuator assembly 20 works within a detent mechanism to bias the lever arm 12 to a desired position. The actuator assembly 20 also provides tactile feedback to the user when pivoting the lever arm 12 between different positions. It should be understood, however, that the scope of the present invention is generally not limited to the use...

Abstract

A plunger-style actuator assembly for use in a detent mechanism includes a guide post and an external plunger sleeve supported for sliding movement over the guide post. The external plunger sleeve rides along bearing surfaces that longitudinally extend between the guide post and the external plunger sleeve.

Description

technical field [0001] The present invention generally relates to plunger actuator assemblies that may be used, for example, to bias an actuation rod assembly to different pivot positions. In particular, the present invention relates to a plunger actuator assembly having a guide post and an outer plunger sleeve supported for sliding movement over the guide post. Background technique [0002] A typical actuation lever assembly, such as in a multi-function toggle lever assembly, for example, includes a lever arm supported for pivotal movement on a base structure. In order to bias the lever arms to different positions, a plunger actuator assembly may be provided on the actuation lever assembly. A typical plunger actuator assembly includes a hollow guide post extending from a lever arm and having an open distal end. The inner plunger member is supported for sliding movement within the hollow guide post, and the distal end of the plunger member extends from the open end of the ...
