Patent number: 11603683Abstract: A lid opening and closing device for a vehicle includes a restriction member that is operable between a restriction position at which the restriction is applied and a restriction release position at which the restriction is released, an electric motor that drives the restriction member between the restriction position and the restriction release position in response to a door switching between a locked state and an unlocked state, a case that houses the restriction member and the electric motor, and an emergency operation member that can move the restriction member to the restriction release position when the electric motor malfunctions, wherein an operating force-acting direction conversion mechanism is provided between the emergency operation member and the restriction member, the operating force-acting direction conversion mechanism converting the operating force from the emergency operation member into a force that causes operation from the restriction position toward the restriction release position.Type: GrantFiled: February 25, 2019Date of Patent: March 14, 2023Assignee: Kabushiki Kaisha Honda LockInventors: Kohei Hirotani, Takashi Yamamoto, Naruhiko Maeda

Patent number: 11279224Abstract: A lid opening and closing device for a vehicle which includes a restriction member that can operate between a restriction position at which movement of a rod at the lid closed position is restricted and a restriction release position at which the restriction is released, an electric motor that operates for a predetermined time in response to a door switching between a locked state and an unlocked state for driving the restriction member, and a case that houses the restriction member and the electric motor, wherein at least the restriction release position of the restriction member is resiliently held by a holding mechanism. Thus, even when the restriction member stops at position halfway between the restriction release position and the restriction position, convenience is enhanced by carrying out an operation of locking the door by moving the rod to the lid closed position without requiring an unlocking operation.Type: GrantFiled: February 25, 2019Date of Patent: March 22, 2022Assignee: Kabushiki kaisha Honda LockInventors: Kohei Hirotani, Hiroyuki Kouzuma, Takashi Yamamoto
