Hood overslam bumper for automobiles
First Claim
1. The combination of a hood overslam bumper, a chassis and a hood of an automobile, comprising:
- a first bumper member mounted to a lower surface of the hood and having elasticity; and
a second bumper member which comprises a compressible cushion member mounted to a top surface of an upper member of the chassis at a position corresponding to said first bumper member, thus being brought into elastic contact with the first bumper member when the hood is slammed down, said cushion member being hollow, thus having a cavity;
a rod interiorly set in a top center of said hollow cushion member and vertically extending downward within said cavity of the cushion member;
a cup-shaped housing set in said hollow cushion member, thus defining a lower portion of the cavity and structurally supporting the cushion member; and
a biasing member positioned in said cavity of the cushion member and being stopped by the rod and the housing, thus normally biasing a top wall of said cushion member upwardly.

Abstract
A hood overslam bumper for automobiles has an elastic member, which is mounted to a hood inner panel, and a spring-biased hollow cushion member which is mounted to the upper member of a chassis. The spring of the cushion member is selected from a compression coil spring, a pneumatic spring and a hydraulic spring. When a hood is slammed down, the hood is made to slowly close with the elastic member gradually compressing the spring-biased top wall of the hollow cushion member. Therefore, the hood overslam bumper of this invention effectively absorbs and reduces the slamming impact noises and vibrations occurring in the slamming of a hood, thus allowing a car to be almost completely free from such noises and vibrations.
