In a mechanical fastening work method in an augmented reality space, a mechanical fastening part and a mechanical fastening part virtual body correspond one-to-one, and a tool and a tool virtual body correspond one-to-one. An augmented reality configuration system generates an augmented reality space including: a camera that captures a real space; a server that analyzes an image captured by the camera and generates the augmented reality space; and a tool that acquires torque information observed when tightening or loosening the mechanical fastening part and transmits and receives the torque information to and from the server. The mechanical fastening work method includes a step of, when the tool detects torque information that the mechanical fastening part is to be tightened or loosened, defining the mechanical fastening part virtual body corresponding one-to-one to the mechanical fastening part, and making the defined mechanical fastening part virtual body appear in the virtual space.

An airbag includes: a first inflatable section that is inflated and deployed forward from the upper portion of a seat back through the left side of a head of an occupant; a second inflatable section that is inflated and deployed forward from the upper portion of the seat back through the right side of the head of the occupant; and a third inflatable section that is continuous with lower portions of front portions of the first inflatable section and the second inflatable section and that is inflated and deployed in front of the chest of the occupant. The front portions of the first and second inflatable sections extend in directions intersecting the vehicle front-rear direction so as to be closer to each other toward the front side. The front portions meet each other at a front end of the airbag.

In an operation management system in the related art, it is necessary to add an identification mark such as an RFID tag to each component to be managed and prepare a fastening tool having an antenna. In contrast, a mechanical fastening unit management method is provided using an augmented reality space generated by superimposing a virtual space on a real space. In the augmented reality space where a real fastening unit (RBn) and a virtual fastening unit (IBn) are in a one-to-one correspondence, information that the real fastening unit is selected as a fastening target is acquired with a camera or the like, and analyzed by an augmented reality server connected to the camera. Accordingly, it is possible to easily record that a predetermined operation is progressing as scheduled, and to provide a high quality mechanical fastening unit management method or system that is low in operation cost.

Provided is an occupant leg restraint device suitable for restraining legs of an occupant when an automobile has an oblique collision. An occupant leg restraint devicehas an airbagthat inflates in front of legs of an occupant in a front seat of an automobile, and an inflatorfor supplying gas to the lower part of the airbagto inflate the airbagThe airbaghas a first paneon the occupant side and a second panelon the side opposite thereto. A plurality of pocketsrecessed from the first panelin the direction away from the occupant are provided in the upper part of the airbagKnees N of the occupant enter the pocketsand fit into and engage with the pocketsand the lateral movement of the knees N is thereby restrained.

Occupant leg restraint device

Provided is an occupant's leg restraint device suitable for restraining the legs of an occupant when an automobile has an oblique collision or an offset barrier collision. The occupant's leg restraint device has an airbag and an inflator for supplying gas to the lower part of the airbag to inflate the airbag, and the airbag has a first panel on the occupant side and a second panel on the side opposite thereto. An upper part of the inside of the airbag is divided into small chambers by vertical separating panels that are joined to the first panel and the second panel and that extend vertically. In a state where the airbag has inflated, recessed portions having a depth of 20 to 40 mm are formed in the occupant-side surface of the airbag along the vertical separating panels.

To provide an airbag device and a steering wheel capable of improving the operational feeling of horn. An airbag device comprises: an airbag unithaving an airbag, an inflatorfor inflating the airbag, and a coverwhich is disposed to cover said airbag in the folded state, wherein as the coveris pressed, the airbag unitis moved in the pressing direction; a supporting platewhich is fixed to a steering wheel; three springs-for biasing the airbag unitin a direction opposite to the pressing direction; and three horn switches-which are located outside of the springs-in the radial direction of the steering wheel and close to the surface of the coverin relation to the springs-

Airbag device and steering wheel

An airbag, airbag device and method provides a folded airbag that inflates leftward or rightward first and then inflates to a fully deployed shape. An airbag is folded along vertical folding lines into a band-shaped folded body that extends vertically, and the band-shaped folded body is folded along horizontal folding lines into a folded body. When the airbag inflates, a right half portion inflates faster than a left half portion.

Folded airbag and airbag device

A flangeis provided on a plate by bending the plate, the flange being substantially orthogonal to the plate, and a recessed portion, where the flange is missing, is provided between two flanges. A flangeis provided by bending another plate, and a raised portion is provided which protrudes from a parallel sideto flangeat an end portion of flange. An end portion of flangeand end portion of flangeare abutted, and end portion of plateis abutted to an outer side of the circular arc portion of flangefrom the plate. The raised portion is abutted to the recessed portion, and respective abutted portions are welded.
