The branching point is between the pair of the spots. The protective member is formed from a resin. The fixing strip portions is smaller in thickness than the protective sheet portion.
Abstract: A lever-type connector includes a first connector, a second connector, and a lever. The lever is mounted on the first connector, and is configured to pull the first connector and the second connector to each other so as to engage the first connector and the second connector with each other by fitting, due to a rotational manipulation of the lever from a lever rotation start position to a lever rotation completion position. The first connector has a support shaft. The second connector has a cam groove, and a temporary locking projection disposed at an inlet of the cam groove. The lever has a bearing portion which is rotatably supported on the support shaft, and a cam boss which engages with the cam groove. A projection having a tapered portion is formed on an outer side of the cam boss in a connector removal direction.
Abstract: Audio control system and audio control method that can appropriately control sound volume of an audio part while preventing inaccurate determination regarding condition of a passenger are provided. An audio control system includes an audio part installed in a compartment of a vehicle, a photographing part that photographs the compartment from a front side reference position in the compartment and obtains a photographed image also representing distance to an object within a photographing range in the compartment, a determination part that determines, based on the photographed image obtained by the photographing part, at least one of whether or not a passenger other than a driver in the vehicle is asleep and whether or not the passenger is making a call on a mobile phone, and a control part that turns down sound volume of the audio part if the determination part determined the passenger is asleep or making a call.
