  • Patent number: 10414310
    Abstract: In the case of a seat with an armrest on an automobile, an armrest lock mechanism may be released by, for example, the gravitational acceleration (G) in the event of vehicle collision. Accordingly, it is necessary to provide an anti-G spring for biasing to prevent the lock mechanism from being easily released. The purpose of the present invention is to provide an armrest unlocking device that enables a decrease in size of the anti-G spring. In order to solve the problem, provided is an armrest unlocking device in gear, the device operating such that the locking of the lock gear and the sector gear can be released by operating a lever link bracket so as to raise the lock gear, wherein the lock gear has a center of rotation thereof aligned with the position of the center of gravity.

  • Patent number: 10391888
    Abstract: A seat moves along a rail in the front-back direction of a vehicle. A juxtaposed member (receiving member) extending in the front-back direction of the vehicle is joined to a floor or the seat so as to be located next to the rail. A detected portion is provided either to the juxtaposed member or to a member which is located on the floor side or the seat side which moves relative to the floor or the seat to which the juxtaposed member is coupled. A sensor that detects the detected portion is provided either to the juxtaposed member or to the member located on the floor side or the seat side. As a result of this configuration, the installation position of the sensor is less spatially restricted than the case in which the sensor is provided to the rail.
