Spring support struts for vehicle rear door has pair of spring struts with paired springs in each strut adjusted by electric motor

摘要

The spring support for a motor vehicle rear door has two spring struts (200) with internal springs acting between the vehicle bodywork (600) and the door (400). The spring resistance varies along the closing movement of the door. The differential spring action can operate through two springs with an electric motor to operate a variable preload on the springs. The springs can be in rows or in parallel.
