Patent ID: 7618088

Claim:
An automobile hood bumper, comprising: a seat comprising a sleeve which has an axial passage, and an external thread adapted to be screwed into a hole of a support; an upper segment having a rest head and a shank; a connection member that releasably joins the shank to the seat to release said shank when an axial force acting on the upper segment exceeds a predetermined magnitude, whereby the shank moves into the axial passage until the rest head comes to rest at an associated end of said seat; and a deceleration element configured at least one selected from the group consisting of (i) an outside of the shank, and (ii) an inside of the axial passage, to generate a decelerating force by at least one selected from the group consisting of (a) friction, (b) elastic deformation, and (c) plastic deformation, and to decelerate the movement of the shank into the axial passage; wherein the decelerating element is configured such that the decelerating force remains approximately constant when the rest head is displaced until resting against the seat.
