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 the fixed member in a rotational position such that the resilient support is stressed in the proper direction. The resilient support is in the form of an extension of the lever having spring-like properties and secured at its outer end to a fixed member. The lever movement resistance member may be in the form of a stop adjacent the rigid lever, or the valving of a vehicle brake booster against which the lever is urged. In one version of the invention, the resilient lever extension is secured to the fixed member by means of a U-shaped bracket. In another version, the resilient lever extension is secured directly to the fixed member. The resilient lever extension may be integrally formed with the lever as a unitary member or may be rigidly secured thereto.
In a motor vehicle brake assembly comprising a brake actuating element, the improvement comprising a resilient lever assembly comprising a rigid lever and a resilient support at one end thereof, stop means cooperable with said lever and resisting movement thereof in one direction to define a normal position, a fixed member, said resilient support comprising an elongated spring-like element connected to said lever at one end and to said fixed member at its other end, and means securing said resilient support to said fixed member in a rotational position such that said support will be stressed in a direction constantly urging the lever against said stop means, said spring-like element having sufficient resilience to deflect when an operator depresses said lever to actuate said brake actuating element and to return said lever to its normal position when operator pressure is released.
A rigid elongated automotive brake pedal lever assembly or the like mounted on a vehicle having a firewall between an engine and passenger compartment, said lever assembly comprising an elongated spring-like element having an upper end and a lower end, means rigidly securing the upper end of said element to said vehicle firewall, the element extending downwardly in curved fashion from said securing means, a rigid lever secured to and extending downwardly from the lower end of said spring-like element and carrying a brake pedal at a lower end thereof, a rod connected at one end to said lever assembly and extending through said firewall, a stop adjacent said lever, and means holding the stop in a position such that the spring-like element will be stressed in a direction constantly urging the lever against the stop.
