  • Publication number: 20160052488
    Abstract: In a through anchor (10), a guide piece (24) is molded in an area around a through hole (16) in an anchor plate (12), webbing (30) is inserted through an insertion hole (26) in the guide piece (24) in such a way that the webbing is movable along a lengthwise direction, and the webbing (30) is slidably supported on a sliding surface (28) of the guide piece (24). Here, the guide piece (24) is placed only on the whole circumference of the through hole (16) in the anchor plate (12) and allows an entire outer peripheral end surface (12C) of the anchor plate (12) to be exposed. For this reason, the use amount of molding resin of the guide piece (24), which is molded from a relatively high-grade resin, and the cost of the through anchor (10) can be reduced.

  • Publication number: 20160039386
    Abstract: In an anchor (10), an insertion hole (42) is formed piercing through an anchor main body (36), and a belt is inserted through the insertion hole (42). A projection (44) is formed at the anchor main body (36) around the entire periphery of the insertion hole (42), and the projection (44) configures an outer peripheral face of the insertion hole (42). The projection (44) projects out toward the radial direction outer side of the insertion hole (42). The surface area of a portion configured by the projection (44) at the outer peripheral face of the insertion hole (42) can accordingly be increased, and the contact surface area of the belt with the outer peripheral face of the insertion hole (42) can be increased, even when the plate thickness dimension of the anchor main body (36) is reduced. This thereby enables the plate thickness dimension of the anchor main body (36) to be reduced.

  • Publication number: 20150192774
    Abstract: The invention relates to a device that supports work of picking an article from a warehouse and the like, which allows the picking work to be carried out accurately and quickly. The device includes: a camera (20) that photographs an automatically-readable identifier (10) that is attached to a storage location of an article; an information processing unit (40) that detects the identifier from an image photographed by the camera and processes the image of the identifier; and a display (50) that displays information such as image information and text information. The information processing unit processes, based on the detected identifier and picking work order information, image on a specific identifier, and the processed image is displayed on the display at a location related to the identifier.

  • Publication number: 20090260913
    Abstract: A steering apparatus for a vehicle capable of executing a steer-by-wire (SBW) mode in which road wheels are steered by a steering mechanism mechanically disconnected with a steering device. The steering apparatus comprises: a connecting mechanism which can connect the steering device and the steering mechanism mechanically; and an SBW control unit which sets the connecting mechanism to a disconnected state to control the steering mechanism based on an operating amount of the steering device under the steer-by-wire mode, and sets the connecting mechanism to a connected state to switch a steering mode from the steer-by-wire mode to a steer-by-wire backup mode when it has been determined that the steer-by-wire mode cannot be executed properly. The connecting mechanism is set to the disconnected state while being energized and set to the connected state while being non-energized.

  • Publication number: 20060118352
    Abstract: A variable steering angle mechanism for a steering apparatus is comprised of a differential gear unit which includes first through fourth bevel gears, an input shaft, an output shaft and a differential gear casing. The output shaft is aligned with the input shaft. The differential gear casing supports the third and fourth bevel gears meshed with the first and second bevel gears and is rotatable on the axis of the input shaft. A motor rotates the differential gear casing around the axis of the input shaft to vary a ratio between a rotation angle of the input shaft and a rotation angle of the output shaft.
