• the present invention relates to a sash handle assembly for a vehicle and to a method for unlocking this sash handle assembly.
• Some luxury vehicles are fitted with a handle built into their door. These handles provide an improved aesthetic effect because they merge with the rest of the door. They are very discreet.
• Known sash handle assemblies conventionally comprise a base intended to be fixed on the door and a handle connected to the base by a hinge.
• the joint can be horizontal or vertical, which is more common.
• the handle is movable in rotation relative to the base between a rest position in which it is positioned substantially parallel to the base and embedded in the door, and a door open position in which it is inclined relative to the base and therefore deployed.
• the sash handle assemblies also include a handle actuation device housed in the base for bringing it to the open position.
• the actuating device comprises a motor driving the handle by means of gears to bring it towards the open position.
