Abstract

Abstract A resilient lever assembly which incorporates spring action whereby the resilient portion of the assembly constantly urges a rigid lever against a lever movement resistance member connected to the lever. The action is accomplished by securing the resilient support to a fixed member in a rotational position such that the resilient support is stressed in the proper direction. In one form, the resilient support and its securing components comprises a rubber bushing between two sleeves, one fixed to the lever and the other to the fixed member. In another version of the invention, the resilient support is in the form of an extension of the lever having spring-like properties and secured at its outer end to the fixed member. The lever movement resistance member may be in the form of a stop adjacent the rigid lever. In another version, the lever movement resistance member could comprise the valving of a vehicle brake booster against which the lever is urged.
