  • Publication number: 20040262903
    Abstract: In the occupant protection device according to the present invention, a restraint body joined with a driving mechanism is located near a target area of a seated occupant while being surrounded by an interior decoration member. Upon predicting a collision of the vehicle, the driving mechanism is actuated to protrude the restraint body from an opening in the interior decoration member for restraining the movement of the target area upon collision by its side facing the occupant, and when the collision is avoided, the driving mechanism returns the protruded restraint body in the opening of the interior decoration member. The restraint body is provided in the vicinity of its outer periphery with a retaining hole, a clip to be inserted in and retained by the retaining hole, and a guide surface for guiding the clip into the retaining hole for helping the restraint body to return in the opening of the interior decoration member.

  • Publication number: 20040074688
    Abstract: A pedestrian protection airbag system includes a control unit, an airbag, an inflator, a movement unit for moving a cover member to thereby allow the airbag to thrust out from an airbag storage portion smoothly, and a drawing unit for drawing out the airbag. The control unit receives signals from sensors, and can perform detection in two stages. In one of the stages the control unit performs touch detection such that the control unit can anticipate that a vehicle will touch a pedestrian, while in the other stage the control unit performs approach detection before the touch detection such that the control unit detects the pedestrian approaching the vehicle. The movement unit and the drawing unit are actuated by the control unit detecting a pedestrian approaching the vehicle. The inflator is actuated by the control unit detecting calculated touch to the pedestrian.

  • Publication number: 20040066022
    Abstract: A vehicle includes an air bag device for an occupant seated in a rearmost seat. The air bag device includes an air bag, which is accommodated at the rear end portion of the roof of the vehicle in a folded state, and an inflator, which supplies gas to the air bag. The air bag is unfolded downward to be inflated between the rearmost seat and a rear window glass. The air bag device has several functions to effectively protect an occupant seated in the rearmost seat, such as a function to apply a predetermined tension to the inflated air bag, a function to properly restrict the thickness of the air bag, and a function to properly control the unfolding direction of the air bag.

  • Patent number: 6641076
    Abstract: A webbing take-up device that can prevent unintended and unnecessary switching from an ELR mode to an ALR mode. In a webbing take-up device, a cam protrusion and a tongue portion are provided at a cam member that interlocks with a take-up shaft, and a breaking operational portion and an intermediate holding surface are provided at a disc control member. When a switch is made from the ELR mode to the ALR mode, unwinding and taking-up operations of the webbing are each preformed twice in succession so that the webbing take-up device is switched to the ALR mode, in which an ALR pawl engages with an outer-tooth ratchet wheel of a locking wheel. Accordingly, unless the aformentioned switching is carried out by conscious volition of a vehicle occupant, unintended and unnecessary switching from the ELR mode to the ALR mode does not occur.

  • Publication number: 20030195685
    Abstract: A first airbag apparatus of the present invention has an airbag module, which includes an airbag and an inflator, and a displacement mechanism, which displaces the airbag module. The displacement mechanism displaces the airbag module from an original position to a predetermined position when a collision of the vehicle is predicted and displaces the airbag module from the predetermined position to the original position when the predicted collision is avoided. A second airbag apparatus of the present invention has the airbag module and the displacement mechanism, which displaces a support member. The support member displaces the airbag from the original position to the predetermined position before the airbag is deployed. The deployed airbag is supported between the support body that is displaced to the predetermined position and an occupant.

  • Patent number: 6530252
    Abstract: A plurality of closing cylinder devices are provided between a bolster of a press machine and a bed containing a lower mold of a hydroforming device. An upper mold is attached to a slide of the press machine. The upper mold and lower mold come together to form a cavity having the shape of the exterior of the desired molded product. A closing block, being movable between a first position which is between the slide and a crown of the press machine, and a second position, which avoids the slide, permitting free movement of the slide from the crown to the lower mold. When a material to be hydroformed is place in the lower mold, the upper mold is lowered. The closing block is fit into its first position, thereby restricting movement of the slide in the vertical direction. A inner work pressure is provided by a fluid inside the material to be molded.

  • Patent number: 5029770
    Abstract: A webbing retractor wherein a take-up shaft supporting a webbing worn by a seat occupant of a vehicle is rotated in a webbing taking-up direction by an urging force of a take-up mechanism connected to the take-up shaft. The rotation of the take-up shaft in a webbing drawing-out direction is stopped upon detection of a predetermined acceleration of the vehicle, whereupon the take-up shaft is moved by the webbing drawing-out force to lock an intermediate portion of the webbing drawn out from the take-up shaft. The take-up shaft and the take-up mechanism are connected together via a pair of mutually meshing gears. One of the gears is moved together with the take-up shaft in a state in which its engagement with the other gear is maintained when the take-up shaft is moved. Accordingly, the take-up mechansim is not moved when the take-up shaft is moved.

  • Patent number: 4585251
    Abstract: A seatbelt system automatically fastens a webbing to an occupant of a vehicle after he has entered the vehicle and seated in a seat. The wind-up force of a webbing retractor for winding up the webbing is temporarily reduced by a control means in the course of the operation for fastening the webbing to the occupant. Thus, it is possible to eliminate the possibility that the webbing may rub against the body of the occupant during the operation for automatically fastening the webbing to the occupant.
