    Abstract: In an automobile hood, further enhancement of pedestrian protection properties when a pedestrian collides with a rear part of the automobile hood is enabled. An inner panel 2 of an automobile hood 1 includes: a pedestal 7 arranged on an inner side of the inner panel 2 relative to an outer circumferential portion 5 of the inner panel 2; a plurality of units 9 each including an inclined wall 12 rising from the pedestal 7, and a flange 11 continuous with an upper end of the inclined wall 12; and beads 21 and 22 including at least one of a structure for connecting together outer end portions 55 of the inner panel 2 in a height direction Z perpendicular to a sheet thickness direction of the inner panel 2 and a structure for connecting an outer circumferential portion 73 of the pedestal 7 and the outer end portion 55. A plurality of the beads 21 and 22 are provided, and are arranged on a rear portion 1a side of the inner panel 2 in a vehicle length direction (longitudinal direction Y) of a vehicle in which the automobile hood 1 is installed.

    Abstract: In an automobile hood 1, an outer panel 3 and an inner panel 2 are joined together by a plurality of spot-shaped joints 20. The automobile hood 1 has a first-direction joint row 30 in which a plurality of the joints 20 are arranged at an interval from each other in a cross direction X, and a second-direction joint row 40 in which a plurality of the joints 20 are arranged at an interval from each other in a longitudinal direction Y that is perpendicular to the cross direction X. A curvature 1/R1 in a direction along the first-direction joint row 30 in a region of the outer panel 3 corresponding to the first-direction joint row 30 is smaller than a curvature 1/R2 in a direction along the second-direction joint row 40 in a region of the outer panel 3 corresponding to the second-direction joint row 40. An interval X1 between the joints 20 in the first-direction joint row 30 is greater than an interval Y2 between the joints 20 in the second-direction joint row 40.

    Abstract: A composite liftgate (10; 100) for a vehicle comprising:
    an inner panel (12; 102) formed of composite material;
    at least one second panel (14, 16; 104, 106), the at least one second panel (14, 16; 104, 106) being infrared welded to the inner panel (12; 102);
    at least two weld joints (114, 116, 118) each having a weld between the inner panel (12; 102) and the at least one second panel (14, 16; 104, 106), wherein a first (114, 116) of the at least two weld joints (114, 116, 118) is a flat to flat configuration where the weld joint is between a flat surface on the inner panel (12; 102) and a first flat surface on the at least one second panel (14, 16; 104, 106) and a second (118) of the at least two weld joints (114, 116, 118) is a rib to flat configuration where the weld joint is between ribs (120) formed on the inner panel (12; 102) and a second flat surface of the at least one second panel (14, 16; 104, 106).

    Abstract: The hood structure for a vehicle includes: an outer panel defining external appearance; an inner panel provided on a prime mover chamber side of the outer panel; and a stiffener provided in a front portion of the inner panel. The inner panel has: an upper surface section located on a center side of the outer panel; a coupling surface section extending downward from a ridgeline located at a peripheral edge of the upper surface section; and a lower surface section extending from a peripheral edge end of the coupling surface section to an edge side of the outer panel. The stiffener has: a reinforcing surface section joined to the outer panel; and a rear-side fixed section extending rearward from the reinforcing surface section. The rear-side fixed section is fixed to the vicinity of the ridgeline.

    Abstract: A work vehicle of the present invention includes: a hood swingable in the up-down direction between (i) an open position, in which the hood stands to expose the engine room, and (ii) a closed position, in which the hood lies to close the engine room; and at least one damper urging the hood toward the side of the open position. The hood can be opened and closed with a small force. The work vehicle of the present invention is arranged such that the damper (22) is swingable in the up-down direction to (i) rise toward a standing position in response to the hood (20) being swung from the side of the closed position to the side of the open position and (ii) fall toward a lying position in response to the hood (20) being swung from the side of the open position to the side of the closed position. The work vehicle includes an urging mechanism (23) configured to, while the damper (22) is in a position on the side of the lying position relative to an intermediate position (C) at a particular angle, apply to the hood (20) an urging force for urging the hood (20) from the side of the closed position toward the side of the open position against the load of the hood (20).
