Power assist device for a vehicle door
First Claim
1. A power assist device for a vehicle, comprising:
- a door pivotally coupled to a vehicle body, the door having a door panel;
a hinge assembly coupled between the vehicle body and the door to define a hinge axis for the door;
a motor coupled to the door panel having a drive shaft extending outwardly therefrom;
a first spool disposed on the drive shaft for rotation therewith as powered by the motor;
a second spool mounted on the hinge assembly at a spool axle; and
a cable operably coupling the first spool to the second spool, wherein the motor is configured to drive the first spool in a rotational movement and the cable is configured to translate the rotational movement of the first spool to the second spool, and further wherein the movement of the second spool drives an opening and closing movement of the door at the hinge axis.

Abstract
A power assist device for a vehicle includes a door is pivotally coupled to a vehicle body. A hinge assembly is coupled between the vehicle body and the door to define a hinge axis for the door. A motor is coupled to the door and includes a drive shaft extending outwardly from the motor. A first spool is disposed on the drive shaft for rotation therewith. A second spool is mounted on the hinge assembly at a spool axle. A cable is operably couples the first spool to the second spool and the motor is configured to drive the first spool in a rotational movement, and the cable is configured to translate the rotational movement of the first spool to the second spool. The movement of the second spool drives an opening and closing movement of the door at the hinge axis of the hinge assembly.
