## Abstract

A vehicle door handle assembly includes a handle trigger including: an articulated end so that the handle trigger can be movable around the articulated end between a rest position and an open position when a user pulls on the handle trigger, an activation end at the opposite side of the articulated end, to release a latch of the vehicle door, a handle structure intended to be fixed to the panel of the vehicle door, wherein the vehicle door handle assembly further includes a flexible bellow gasket housed into the handle structure and arranged between the activation end of the handle trigger and the handle structure.

## Claims

### Claim 1

A vehicle door handle assembly comprising:
a handle trigger comprising:
an articulated end so that the handle trigger can be movable around the articulated end between a rest position and an open position when a user pulls on the handle trigger, and
an activation end at an opposite side of the articulated end, to release a latch of the vehicle door, the activation end including a rod with a fastening mean configured to be fastened to a flexible cable, the fastening mean being disposed on a free end of the rod;
a handle structure intended to be fixed to the panel of the vehicle door, the handle trigger being connected to the handle structure, a first end of the handle structure including a through-housing intended to pass through a hole of the panel of the vehicle door, allowing the flexible cable to be fastened to the fastening mean of the activation end, and a second end of the handle structure including a cavity which houses a rotation spindle mounted in a cylindrical cavity of the articulated end of the handle trigger; and
a flexible bellow gasket housed into the handle structure and arranged between the activation end of the handle trigger and the handle structure,
wherein a first end of the flexible bellow gasket is fixed to the activation end around the rod and a second end of the flexible bellow gasket is arranged at an opening of the through-housing inside the handle structure, and
wherein the flexible bellow gasket is squeezed in the rest position and is expanded in the open position.
