Claim:
A vehicle inside door handle assembly, comprising: a housing securely fastened to a door inner panel positioned opposite to a door trim while being fit into a mounting aperture of the door trim, the housing having a hollow space defined therein; a door inside handle installed so as to pull a rod member positioned opposite to the door trim such that a door latch is unlocked, wherein the handle is formed at one end with a hole for inserting a hinge pin thereto and an extended piece bent pointing to the inner space of the housing at a given angle with respect to the hinge pin, the extended piece having a connection pin formed at one end thereof, the handle being mounted in the housing to be pivotally moved inwardly into the inner space of the housing about the hinge pin to its unlatched position by means of a pushing force of a driver or passenger exerted toward the interior of the housing and to be returned to its latched position by means of a resilient restoration force of the spring when the pushing force is released; and a linkage mechanism connected between one end of the handle and one end of the rod member via a through-hole of the housing, for converting the pivotal force of the handle exerted toward the interior of the housing into the pulling force of the rod member; wherein the linkage mechanism includes: a first linkage rod connected at one end to the extended piece of the handle, the first linkage rod being longitudinally formed at both ends thereof with opposite guide slots and at a central portion thereof with a first pin mounting hole for inserting a first hinge pin for fixedly mounting to the housing, so that the first hinge pin is fit into the first pin mounting hole of the first linkage rod to allow the first linkage rod to pivotally rotate about the first hinge pin while the first connection pin of the extended piece being slidably guided in a guide slot formed at one end of the first linkage rod; and a second linkage rod connected at one end to the other end of the first linkage rod and connected at the other end to one end of the rod member, the second linkage rod being formed at the central portion thereof with a second pin mounting hole for inserting a second hinge pin for fixedly mounting to the housing and formed at one end with a second connection pin, so that the second hinge pin is fit into the second pin mounting hole of the second linkage rod to allow the second linkage rod to pivotally rotate about the second hinge pin while the second connection pin is slidably guided in a guide slot formed at the other end of the first linkage rod, whereby when the handle is pivoted inwardly into the inner space of the housing to its unlatched position the first and second linkage rods are pivotally rotated about the first and second hinge pins, respectively, in an opposite direction to each other to thereby pull the rod member.
