1. A door handle assembly, comprising:
a frame to be mounted to a door, the frame including a housing portion and an exterior surface having a cavity;
a mechanical deployment unit disposed in the housing portion, the mechanical deployment unit including a leading actuation component, a trailing actuation component, and a biasing mechanism; and
a handle disposed in the cavity and operably coupled to the mechanical deployment unit, the handle being pivotable within the frame such that the handle is moveable between an undeployed position, in which the handle is flush with the exterior surface, and a deployed position, in which the handle protrudes from the cavity,
wherein, when the handle is in the undeployed position, the leading actuation component and the trailing actuation component abut opposite sides of an actuator member of the handle,
wherein a first actuation on the handle moves the handle toward the frame, the leading actuation component and the biasing mechanism move the handle from the undeployed position to the deployed position after release of the first actuation, and the handle moves from the deployed position to the undeployed position by the trailing actuation component and the biasing mechanism after release of the handle from the deployed position,
wherein the mechanical deployment unit is configured to hold the handle in the undeployed position before the first actuation and after a second actuation, and
wherein only the actuator member of the handle extends into the housing portion of the frame when the handle is in the undeployed position and the deployed position.
