Patent number: 11686130Abstract: Embodiments of systems and methods for operating a power tailgate system include overload checking a tailgate latched by a latch that is in a full-latching position, connected with a latch actuator, and activated by the latch actuator for non-revertible movement in a latching direction. Overload checking the tailgate includes operating the latch actuator to over-stroke the latch, identifying an over-stroking load on the latch actuator, and based on the over-stroking load on the latch actuator, determining whether the tailgate is overloaded or not overloaded. Over-stroking the latch includes moving the latch in the latching direction from the full-latching position to an over-stroking position, and the over-stroking load on the latch actuator is associated with its operation to over-stroke the latch.Type: GrantFiled: December 17, 2019Date of Patent: June 27, 2023Assignee: Aisin Technical Center of America, Inc.Inventors: Koji Nagase, Daisuke Yamada, Emiko Okuma, Yasuo Imatomi

Patent number: 8328250Abstract: A door handle for a door of an automotive vehicle having a first gasket attached at a distal end of the door handle and a second gasket attached at a proximate end of the door handle. The first gasket and second gasket have an inner surface facing the outer surface of the door and an outer surface facing the respective ends of the door handle. The first gasket and the second gasket also include a lip formed of a resilient material, which protrudes outwardly relative to the outer surface of gaskets and extends longitudinally along the edge of the gaskets to sealingly engage the ends of the door handle. The lip is embossed so that it is recessed relative to the inner surface of the gasket to accommodate compression of the lip as the handle is displaced towards the door. A flattened portion extends from an end of the lip on the first gasket to dampen noise due to impact between the distal end of the door handle and an outer surface of the door.Type: GrantFiled: October 22, 2009Date of Patent: December 11, 2012Assignees: Toyota Motor Engineering & Manufacturing North America, Inc., Aisin Seiki Co., Ltd., Aisin World Corp. of AmericaInventors: Eric M.
