Abstract

A door handle for a door of a vehicle includes a handle portion and a housing or base portion. Preferably, the handle portion is assembled to the base portion by a snap fit of a pair of snap clasps onto a corresponding pair of axles or cross members attached to the housing. The snap clasps engage the cross members via a tapered opening to guide the cross members into the snap clasps, thereby easing the assembly process of the handle assembly. The snap clasps are snapped onto the cross members marked by an audible click to pivotally secure the handle portion to the housing, such that pivotal movement of the handle relative to the housing may be operable to open the door of the vehicle. Preferably, a biasing member is included to bias the handle portion toward its closed position relative to the housing, while the handle and the housing comprise polymeric materials. Also, the handle preferably comprises a soft touch material molded along an inner or back side of the handle to improve comfort of the handle to a user thereof when the user grasps the handle to open the door, and a heating element may also be included. One or more illumination sources may be provided at the housing or otherwise adjacent to the handle to provide illumination of the handle in response to electrical signal.
