  • Patent number: 6470746
    Abstract: An object of the present invention is to obtain an acceleration sensor that can reliably detect acceleration when inclination of an inclining member is within a fixed range, and that can reduce unnecessary movement of relevant members when inclination of the inclining member is outside of the range, so that space efficiency in an inner portion is high. In the present invention, a gear of a fixed gear fixed at a seat cushion is formed in only a portion in the circumferential direction, and a portion at which the gear is not formed is a sliding surface. One of teeth among a plurality of teeth of a pinion of a revolving gear is short, to form a notched tooth portion. In a state in which the forward-collapsed angle of a seatback exceeds a predetermined angle, the notched tooth portion faces the sliding surface and the revolving gear body no longer rotates. At this time, since a bracket at which a sensor ball is mounted also does not rotate, the bracket is held at a fixed position relative to a frame plate.

  • Publication number: 20020137115
    Abstract: As a cGMP-visualizing probe capable of detecting and quantifying cGMP easily and accurately even in vivo and for a method of detecting and quantifying cGMP by using the same, a cGMP-visualizing probe comprising a polypeptide, which binds specifically to cGMP, and two chromophores having different fluorescence wavelengths each linked respectively to the two terminals of said polypeptide is provided.

  • Patent number: 6312014
    Abstract: A shoulder anchor position adjusting device is provided in which assembly of a position adjusting mechanism, which adjusts a position of a shoulder anchor, is easy. The shoulder anchor is fixed to a slider. The slider is slidably mounted to a slide rail by the position adjusting mechanism which has a lock pin and a release lever. The release lever is placed on the slider in which a stepped groove is formed. The release lever is swingably held due to engagement of an anchor plate of a cover case with a cut-out groove. A flange portion is formed at the lock pin, and is supported by a step forming portion of the stepped groove. Due to a coil spring, a shaft portion of the lock pin is inserted through an insertion hole of the slider and is fit into an engagement hole formed in the slide rail.

  • Patent number: 5351908
    Abstract: A webbing retractor winds-up a webbing by a winding shaft. A lock ring rotates according to movement of the winding shaft. A rotational delay of the lock ring with respect to the winding shaft is generated when the webbing is rapidly drawn-out. The rotational delay of the lock ring causes a lock plate to prevent the webbing from being drawn-out. An engaging member is movable to a separated position where the engaging member is separated from the lock ring, and to an engaging position where the engaging member engages the lock ring to generate rotational delay. Further, the engaging member is urged in one of the direction of the separated position and the direction of the engaging position when the engaging member is separated from a neutral position disposed at an intermediate portion between the separated position and the engaging position. A moving member moves with the winding shaft and rotates.
