Vehicle tailgate dampener and lift assist system
First Claim
1. A control mechanism for controlling movement of a vehicle gate between a first position and a second position, the control mechanism comprising:
- a dampener assembly having a first dampener component mountable to a vehicle structure and a second dampener component supportable by a vehicle gate mounted for movement relative to the vehicle structure wherein said first dampener component and said second dampener component cooperate to control vehicle gate speed as the vehicle gate is moved from the first position to the second position; and
a lift assembly including a spring operatively coupled to said dampener assembly to reduce lifting effort as the vehicle gate is moved from the first position to the second position wherein at least said second dampener component and said spring are mountable to the vehicle gate wherein said first dampener component comprises a cable and said second dampener component comprises a piston slidably received within a cylinder with said cable being attached to said piston with a rod.

Abstract
A control mechanism for controlling movement of a vehicle gate between a first and a second position comprises a dampener assembly and a lift assembly that are incorporated within the gate. The dampener assembly has a first component mountable to a vehicle structure and a second component supportable by the vehicle gate mounted for pivotal movement relative to the vehicle structure. The first and second components cooperate to control vehicle gate speed as the vehicle gate is moved from the second position to the first position. The lift assembly includes a spring operatively coupled to the dampener assembly to reduce lifting effort as the vehicle gate is moved from the first position to the second position.
