Patent number: 7036857Abstract: A vehicle inside door handle assembly has an inside door handle pivotally mounted to a mounting bracket. A biasing element is operatively disposed between the handle and the mounting bracket to urge the handle from a latch releasing position to a latching position. The handle has an operating portion and a counterweight portion. The counterweight portion is configured to counteract pivoting of the handle when a lateral force is applied to the handle in a plane substantially perpendicular to a pivot axis of the handle and substantially opposite to an urging force on the operating portion of the handle by the biasing element. The mounting bracket has an upper flange with an abutment surface disposed outwardly relative to the counterweight portion to prevent a door trim panel from being deflected against the counterweight portion of the handle.Type: GrantFiled: December 22, 2003Date of Patent: May 2, 2006Assignee: Nissan Technical Center North America, Inc.Inventor: Takehito Ichino

Patent number: 6942277Abstract: A door hinge assembly is mounted between a door mounting pillar of the vehicle body and a door to swingably mount the door to the door mounting pillar. The door hinge assembly includes an upper hinge and a lower hinge with a double pivot pin arrangement, and a torsion bar extending substantially vertically between the upper and lower hinges. The upper and lower hinges are fastened at interior fastening points on an inner side wall of the door mounting pillar and at exterior fastening points on an exterior wall portion of the door mounting pillar with longitudinal fastening axes that extend in a substantially orthogonal direction to the inner side wall and the exterior wall portion of the door mounting pillar. The interior fastening points are disposed rearwardly of the torsion bar and the exterior fastening points are disposed forwardly of the torsion bar.Type: GrantFiled: December 22, 2003Date of Patent: September 13, 2005Assignee: Nissan Technical Center North America, Inc.Inventors: Nandkumar Rangnekar, William Bowes, Gary Nylander, William Spencer Evans, Takehito Ichino
