  • Patent number: 7055872
    Abstract: A door lock device includes a latch mechanism, a lift lever, an open lever, a lock lever, an open member including a link member having an operation input portion connected to the open lever and an acting portion engageable with the lift lever, and an elastic member connecting the link member and the lock lever. When the open member is in the unlocked position, the open member engages with the lift lever by an operation of the open lever in one direction thereby allowing an operation of the lift lever. When the open member is in the locked position, the open member idly engages with the lift lever by the operation of the open lever and then becomes engaged with the lift lever in the other direction thereby prohibiting the operation of the lift lever when the open member is switched to the unlocked position from the locked position.

  • Publication number: 20060107767
    Abstract: In a seat load detecting device, sensor bodies are interposed between an upper rail and respective lower brackets. Each sensor body includes an annular strain portion which axial line extends vertically, an outer peripheral holder which is mounted to the upper rail and which holds an outer peripheral edge of the strain portion, and an inner peripheral holder which is mounted to the lower bracket and which holds an inner peripheral edge of the strain portion. Strain gauges for detecting a load applied to a seat on the basis of a strain amount between an outer periphery and an inner periphery of each strain portion are disposed on each strain portion. A second clamping member of each inner peripheral holder has a mounting hole which is formed through the second clamping member in a widthwise direction thereof and which rockably connects the lower bracket.

  • Patent number: 7021681
    Abstract: A door lock device includes a latch mechanism, a lift lever, an open lever, a lock lever including a main lever and a sub lever mounted on the main lever so as to relatively rotate thereto, a biasing member disposed between the main lever and the sub lever, and an open member. When the open member is in the unlocked position, the open member engages with the lift lever by an operation of the open lever in one direction thereby allowing the lift lever operable. When the open member is in the locked position, the open member idly engages with the lift lever by the operation of the open lever and then becomes engaged with the lift lever in the other direction thereby prohibiting the lift lever operable when the open member is switched to the unlocked position from the locked position.
